Pay-roll Tax Assessment Regulations 2003

The Regulations articulate and operationalise several recurring legal and administrative concepts from the Act. These include the following.

• Wages and specified taxable benefits. The Regulations expand the Act’s statutory definitions by prescribing that certain employer payments are to be treated as wages (for example, amounts under ship or boat building procurement contracts, reg 5) or as specified taxable benefits (contributions to redundancy benefits schemes and portable long service leave funds, rr 11, 13). For those specified benefits the Regulations also fix valuation rules: the value equals the amount of the contribution (rr 12, 14) and wages paid to an employee are exempt to the extent the employer can recover amounts from the scheme or fund (r 15).

• Fringe benefits and remote location exceptions. The Regulations implement a set of exemptions for fringe benefits provided in remote locations, tying the payroll tax treatment to the FBTA Act’s valuation and reduction rules. They prescribe that certain expense payment, property and residual fringe benefits provided in respect of dependants’ education costs or domestic water, residential fuel, housing, electricity, gas or remote area holiday transport are exempt to the extent the FBTA Act would reduce their taxable value (rr 8-10).

• Motor vehicle allowance measurement methods. The Regulations set out two measurement regimes for motor vehicle allowances: the continuous recording method and the averaging method (rr 32-36). They prescribe when each method may or must be used, how to select a recording period (r 36), how to calculate the BK percentage and average business kilometres (r 35), record requirements (r 34), and transitional rules when vehicles are replaced or odometers recalibrated (rr 37-38).

• Actuarial determinations for superannuation contributions. Where superannuation contributions are taken to be wages under s 9CB of the Act, employers must ensure an actuarial determination is in force for the return period (r 41). The Regulations set who may supply determinations (an actuary), allow category‑based notional averaging (r 42), define required content (r 44), and limit the duration of determinations to three years unless replaced earlier (r 45).

• Record keeping and retention. Regulation 46 prescribes the categories of documents employers must keep to satisfy s 44(1)(a) of the Act and the kinds of wages/benefits to which this applies (r 46(1)-(2)). It also prescribes documentary evidence required when claiming certain leave related exemptions (r 46(3A)) and sets retention periods (r 46(4)).

• Electronic lodgement and payment. Regulation 47 prescribes the manner of lodging returns and paying payroll tax as the electronic online systems provided by the Commissioner and authorised methods of electronic funds transfer. The Commissioner may approve exceptions in writing (r 47(2)-(4)).

• Commissioner discretion and administrative direction. Multiple provisions grant the Commissioner powers to direct employers (for example, to require continuous recording r 32(2)(c), to specify deemed kilometres r 32(4)(b), to approve non‑electronic lodgement r 47(2), and to require a new actuarial determination r 41(3)). These are working administrative controls that affect measurement and compliance.

• Statutory linkage to federal instruments. The Regulations explicitly adopt federal measures in two ways: by treating some fringe benefit exemptions as contingent on reductions under the FBTA Act (rr 9-10) and by prescribing a Commonwealth wages subsidy under a named Deed as a “disability wages subsidy” for s 41C purposes (r 16). The Regulations also contain notes on Commonwealth modification schemes for application in Commonwealth places (Glossary and Notes referencing 1M and 1MC modifications).

These concepts establish the measurement rules that determine payroll tax base adjustments, valuation points, employer record obligations, and administrative levers available to the Commissioner. Each concept is tightly specified in the cited regulations and in the Glossary definitions (Gl. entries such as BK percentage, business kilometre, vehicle, continuous recording period) which the Regulations rely on for technical meaning.

The Regulations primarily affect employers who are taxpayers under the Pay-roll Tax Assessment Act 2002, and more specifically employers who:

• pay or account for fringe benefits, motor vehicle allowances, accommodation allowances, shares or options taken to be wages under ss 9DA or 9DG, employer superannuation contributions treated as wages under s 9CB, or make contributions to redundancy benefits schemes or portable long service leave funds (r 46(2));

• pay motor vehicle allowances to employees and therefore must adopt and document either the continuous recording or averaging method, with the related odometer and journey purpose records (rr 30, 32-38, Glossary definitions);

• rely on or administer remote location benefits or fringe benefits linked to the FBTA Act’s remote area provisions, including employees who live and work in remote areas and their employers (rr 7-10, Glossary definitions such as dependant, remote area housing fringe benefit);

• make contributions to redundancy benefits schemes or portable long service leave funds; the Regulations treat those contributions as specified taxable benefits and prescribe valuation (rr 11-15);

• make employer superannuation contributions that the Act treats as wages under s 9CB; these employers must ensure an actuarial determination is in force and updated where significant events occur (rr 41-45);

• claim exemptions for maternity, parental or adoption leave under s 41A(2); such employers must retain prescribed documentary evidence (r 46(3A));

• lodge returns or pay payroll tax; r 47 prescribes electronic lodgement and payment processes, subject to Commissioner approval for exceptions (r 47(2)-(4)). Employers with low annual payroll liability may be exempt from monthly returns if below the prescribed $150,000 threshold (r 48).

The Commissioner of State Revenue (the Commissioner) is a central decision maker under the Regulations. The Commissioner approves departures from electronic lodgement (r 47(2)), may direct employers to change recording methods (r 32(2)(c), r 36(2)), may specify deemed business kilometres or allow estimates (r 32(4)), and may direct employers to obtain new actuarial determinations where circumstances change materially (r 41(3)). These powers allocate administrative discretion to the revenue authority.

Schedule 1 lists a set of public bodies and departments that are prescribed for the purpose of s 40(2)(q) of the Act (reg 4 and Schedule 1). That list affects those bodies by prescribing them as exempt in specified circumstances set out in the Act. Regulation 4 also contains an operative date applying to the Health and Disability Services Complaints Office from 1 September 2018.

Accountants, payroll officers and in‑house counsel of affected employers will bear the principal operational burden of implementing the record keeping, measurement and lodgement requirements found through Part 3 (motor vehicle allowances), Part 4 (superannuation actuarial rules), Part 5 (records), and Part 6 (returns). Actuaries and advisors are the professionals called on to supply actuarial determinations under regs 41-45.

The Regulations therefore affect a wide range of employers from private businesses hiring employees and procuring contractor labour under reg 5 to public sector agencies listed in Schedule 1 that are prescribed for particular exemptions.

The Regulations create specific duties and confer practical rights as follows.

Key duties on employers

• Determine and document whether payments fall within prescribed classes of wages or specified taxable benefits. For example, amounts under ship or boat building procurement contracts are wages where the contract procures labour primarily for design, construction, fit‑out or maintenance of a ship or boat (reg 5). Certain contracts are explicitly excluded (reg 6). Contributions to redundancy benefits schemes and to portable long service leave funds are specified taxable benefits and must be valued as the amount of the contribution (rr 11-15).

• Maintain specified records. Under reg 46 employers must keep documents and records evidencing provision of wages or benefits listed in r 46(2), records used in valuation calculations, and other records required by the Regulations. Employers claiming the leave‑related exemption in s 41A(2) must retain medical certificates or statutory declarations as prescribed (r 46(3A)). Employers using the estimated value method for WA fringe benefits must keep the last actual value record and retain it for five years subject to r 46(4).

• Follow motor vehicle allowance measurement rules. Employers paying vehicle allowances must calculate business kilometres using one of the specified methods. Where the continuous recording method is used, they must keep odometer readings for each business journey and document the purpose of each journey (r 34). Where the averaging method is used, they must establish a BK percentage over at least 12 consecutive weeks, and comply with the transition rules and five‑year durability for a BK percentage (r 35).

• Ensure actuarial determinations are in place where superannuation contributions are taken as wages. Employers must ensure an actuarial determination is in force for the return period and obtain a new determination after a significant event that could reasonably be expected to affect the prior determination’s accuracy. The Commissioner may direct a new determination (r 41(1)-(4)). The content and duration of determinations are prescribed in regs 42-45.

• Lodge returns and pay payroll tax electronically by the Commissioner’s systems, unless the Commissioner approves an alternative in writing (r 47(1)-(4)). The Commissioner’s approval remains in force until the end of the first 30 June following the approval date (r 47(3)).

• Provide the Commissioner with a copy of any amended FBTA Act assessment they receive within 30 days of receipt. Failure attracts a penalty of $5,000 (r 27).

Key administrative powers and rights

• Commissioner direction. The Commissioner may require employers to change recording methods for vehicles (r 32(2)(c)), may accept reasonable employer estimates of business kilometres or specify deemed numbers where methods cannot be used (r 32(4)), may direct employers to obtain new actuarial determinations (r 41(3)), may direct selection of another continuous recording period (r 36(2)), and may approve exceptions to electronic lodgement (r 47(2)). Those are regulatory powers to preserve measurement integrity.

• Averaging method durability. Once an employer establishes a BK percentage under r 35(2) it may use that BK percentage for up to five years unless specified conditions occur (r 35(4)). That creates a limited entitlement to stability in the averaging measurement.

• Express linkage to federal reductions. The Regulations provide that certain remote area fringe benefits are exempt to the extent they would be reduced under specific FBTA Act provisions, and in one case (remote area holiday transport reduced under s 60A of the FBTA Act) the exemption equals twice the reduction (r 10(5)). This is a drafting choice that ties payroll tax treatment to federal valuation mechanics.

Statutory limits and durations

• Actuarial determinations must specify contributions for each return period during the three years after the determination is made and remain in force for three years unless replaced earlier (rr 44-45).

• BK percentages established for a vehicle are usable for five years from the end of the continuous recording period unless usage changes materially or the Commissioner directs otherwise (r 35(4)).

Record retention

• Certain records must be kept for at least five years, including records made under r 37 regarding replacement vehicles and records held after a change from the actual to estimated value method for WA fringe benefits (r 46(4); r 37(4)).

These duties and rights are concrete inputs to employers’ compliance operations: they determine what documentation must be held, what measurement method applies to motor vehicle allowances, when to commission actuarial work, how to treat specified employer contributions, and how to make returns and payments.

The Regulations contain a limited number of explicit penalties and a broader set of enforcement mechanisms that vest operational discretion in the Commissioner.

Explicit penalty

• Failure to give the Commissioner a copy of an amended FBTA Act assessment within 30 days attracts a fixed penalty of $5,000 (r 27). The scheme frames this as a stand‑alone criminal or civil penalty attached to a specific reporting duty. No other monetary penalties are specified within the Regulations text provided.

Administrative enforcement and discretionary powers

• Direction powers. The Commissioner may issue directions that affect measurement and compliance. Notable examples include power to direct an employer to use the continuous recording method for vehicle allowance calculations (r 32(2)(c)), to direct the selection of another recording period under r 36(2), and to direct an employer to obtain a fresh actuarial determination where a determination is no longer accurate (r 41(3)). Those directions are enforceable duties under the Act and Regulations; the text does not set out internal appeal rights in the Regulations themselves, so enforcement would proceed under the Act’s general compliance and appeal provisions.

• Deemed values and allowances for estimates. Where an employer cannot use either the continuous or the averaging method, the Commissioner may allow a reasonable estimate to be used (r 32(4)(a)), or may specify a number that is taken to be the business kilometres (r 32(4)(b)), or otherwise the kilometres may be taken as zero (r 32(4)(c)). This provides the Commissioner with a tool to remedy non‑compliance or measurement gaps, but it also places employers at risk of the Commissioner imposing deemed values (which may be unfavourable) where no reasonable estimate is accepted.

• Approval of non‑electronic lodgement. The Commissioner may approve, in writing, particular employers not complying with the mandatory electronic lodging and payment rules (r 47(2)). An approval remains in force until the end of the first 30 June after the approval is given (r 47(3)).

Record retention enforcement

• The Regulations mandate record keeping and retention (r 46). The Act contains wider compliance, audit and penalty provisions (not reproduced here). The Regulations’ retention periods (for example five years in r 46(4); r 37(4)) create an evidentiary burden that enforcement officers may rely on during audits.

Indirect enforcement via measurement rules

• The rules on valuation (rr 12, 14: value equals amount of contribution) and exemptions (r 15: wages exempt to the extent the employer is entitled to recover from the scheme or fund) create legal entitlement rules that inform assessments and potential reassessments by the Commissioner. The Commissioner’s power to direct actuarial determinations affects timing and content of valuations and thereby enforcement assessments.

Limits in the Regulations

• The Regulations themselves do not set out an exhaustive penalty schedule. Apart from r 27, monetary sanctions, interest on unpaid tax, criminal sanctions, and objection and appeal processes are matters dealt with in the Act rather than in the Regulations. The Regulations, however, set the compliance obligations the Commissioner will enforce, and give the Commissioner powers to specify or substitute measurement where employers cannot comply with methods set out in the Regulations.

In summary, enforcement under the Regulations operates through a mix of a single explicit fine, record‑keeping obligations, and significant administrative discretion that the Commissioner can use to require particular measurement methods, accept or reject estimates, and mandate actuarial re‑determinations. Employers therefore face both prescriptive compliance obligations and the operational risk of the Commissioner exercising statutory direction powers where measurements are deficient or circumstances change.

The Regulations are explicitly drafted to operate alongside the Act and to reference Commonwealth legislation where federal valuation or subsidy rules are relevant. The text itself creates multiple linkages.

Linkage to the Pay-roll Tax Assessment Act 2002

• The Regulations implement, clarify and prescribe details required by provisions of the Act. They repeatedly cite the Act as the enabling source: reg 4 prescribes organisations for s 40(2)(q) of the Act; reg 5 prescribes a class of contract as wages for s 9AA(1)(c); regs 11-15 operate for purposes of ss 45 and 9BI; regs 30 and following implement s 9FA(2) on motor vehicle allowances; regs 41-45 implement actuarial determination duties where s 9CB takes superannuation contributions to be wages; r 46 addresses records for s 44(1)(a) and s 41A(2); r 47 implements s 28A(1) on manner of lodging returns; r 48 prescribes the amount for s 29(1aa)(b). The Regulations therefore must be read in conjunction with the Act to identify the full compliance and enforcement framework.

Linkage to the FBTA Act (federal fringe benefits rules)

• Several exemptions for remote location fringe benefits are drafted to depend on reductions under specified sections of the FBTA Act. Regulation 9(1) refers to reductions under s 59 of the FBTA Act for residential fuel; reg 10(3)-(5) reference ss 60, 61 and 60A of the FBTA Act in relation to remote area housing, utilities and holiday transport. The Regulations therefore import federal valuation adjustments to determine WA payroll tax exemptions. Practically, employers must be familiar with the FBTA Act valuation rules to apply payroll tax treatment correctly.

Linkage to Commonwealth programmes and Deeds

• Regulation 16 prescribes that a Commonwealth “wages subsidy provided under the Deed entitled ‘Disability Employment Services Deed’” is a “disability wages subsidy” for s 41C(1)(b) of the Act. This explicitly recognises a federal funding arrangement as relevant to state payroll tax treatment, and sets an operative date for wages paid or payable on or after 4 March 2013.

Linkage to industrial relations instruments and other Acts

• Regulation 6 excludes from reg 5 contracts covered by an industrial award, contracts under the (now expired) Workplace Agreements Act 1993, employer‑employee agreements under Part VID of the Industrial Relations Act 1979, and contracts where a registered employer is liable to pay payroll tax under the Act (reg 6(b)-(e)). The Glossary defines “industrial award” to include awards and similar instruments under the Industrial Relations Act 1979 and similar laws. Thus the Regulations operate in a regulatory space that overlaps industrial relations and award coverage.

Commonwealth places and modifications

• The Notes and Glossary contain modification markers (1M and 1MC) indicating that modifications apply when the Act and Regulations are applied as Commonwealth laws in Commonwealth places under the Commonwealth Places (Mirror Taxes Administration) Act 1999 and Commonwealth Places (Mirror Taxes) Act 1998. The Regulations therefore interact with federal machinery to ensure consistency in Commonwealth places.

Operational overlaps and practitioner implications

• The multiple cross‑references mean that an employer or adviser must treat the Regulations as part of a suite comprising the Act, the FBTA Act, and sometimes Commonwealth agreements or Deeds. For remote area fringe benefits, an employer needs to compute the FBTA Act taxable value reductions to determine payroll tax exemption (rr 8-10). For superannuation contributions taken to be wages under s 9CB, actuarial determinations must be prepared in the form prescribed by regulations 41-45, which refer to the Act for the triggering mechanism.

The Regulations therefore act as the State link between the Act and federal valuation or subsidy rules and between payroll tax and industrial law boundaries. Practitioners must read the Regulations in their statutory network context to apply valuation, exemption and record‑keeping rules correctly.

The Regulations have been amended repeatedly since their first publication. The compiled notes in the source list a chronology of regulations, reprints and amendments; a concise summary follows, grounded in the compilation table and in the embedded amendment notes.

Origins and initial commencement

• The Pay‑roll Tax Assessment Regulations 2003 were published 27 June 2003 and commenced 1 July 2003 (see r 2).

Reprints and periodic amendment

• The compilation shows multiple amendment instruments and reprints: amendments in 2003, 2004, 2005 and 2006 with Reprint 1 as at 13 Oct 2006. Further amendments and reprints followed: Reprint 2 as at 14 Aug 2009 and Reprint 3 as at 4 May 2012. The compilation table records amendment regulations in 2006 (multiple), 2007, 2009, 2010 (amendment Act Part 3 assented 25 Jun 2010), 2011 (Public Sector Reform consequential amendments), 2013, 2015, 2016, 2019, 2020, 2021 and 2022.

Notable insertions, deletions and timings

• Division 4A and regulation 16 were inserted 11 October 2013 (Gazette 11 Oct 2013 p. 4624) to prescribe the Commonwealth Deed subsidy for s 41C(1)(b) (r 16).

• Regulation 4 was amended by SL 2021/115 r 4, which also added the Health and Disability Services Complaints Office to Schedule 1 with effect to wages paid or payable on or after 1 September 2018 (see r 4(2) and Schedule 1 amendment notes).

• Regulation 48 was inserted by SL 2022/91 r 8 prescribing the $150,000 amount for s 29(1aa)(b) (see compilation table entry for 2022).

• Several provisions were deleted in the 2010 amendment package: regs 17-18 and regs 19-26 are shown as deleted by Act No. 15 of 2010 s 32 and s 33 respectively. Division 2 (rr 39-40) and other smaller provisions were deleted as part of Act No. 15 of 2010 (see r 38 note).

• Reg 27 (employer to give copy of amended FBT Act assessment to Commissioner) is present and carries a penalty. Reg 47 on electronic lodgement was inserted 2 May 2006 (Gazette 2 May 2006 p. 1711).

• Several amendments and insertions are recorded in the Schedule 1 amendment history, with changes across years 2004, 2006, 2011, 2015, 2020 and 2021.

Modification markers and Commonwealth places

• The Regulations include modification markers 1M and 1MC to indicate provisions that are modified or inserted for application in Commonwealth places under Commonwealth mirror taxes legislation (see Notes and Glossary references to 1M and 1MC). Those marks reflect federal‑state interaction rather than internal WA amendment.

Administrative notes

• The compilation table lists specific instruments that effected amendments and their publication and commencement dates. The compilation also records that the amendments set out in the Pay‑roll Tax Assessment Amendment Regulations 2010 are not included in the compilation because equivalent amendments were made by the Pay‑roll Tax Assessment Amendment Act 2010 Part 3.

Practitioner takeaway

• The Regulations have been updated over time to respond to federal linkages, administrative modernisation (electronic returns), and sectoral or programmatic developments (for example, the disability wages subsidy and new prescribed public bodies). Key recent changes in the compilation include the 2020-2022 instruments that updated Schedule 1 and introduced the $150,000 threshold for the exemption from monthly returns. Always consult the compilation table and reprint notes in the published instrument for precise commencement dates of particular amendments.

The text of the Regulations provided does not record or cite any litigation or cases that have interpreted these specific Regulations. The compilation and Notes sections include amendment and reprint histories but do not list judicial decisions. Therefore, from the source provided there is no litigation history embedded in the Regulations document.

Practitioners should treat the absence of recorded litigation in this source as silence rather than proof of absence: the Regulations interact with the Act, the FBTA Act and administrative decisions by the Commissioner, and disputes arising from assessments, valuation methods, or alleged non‑compliance would ordinarily be litigated under the Act’s objection and appeal framework or in judicial review proceedings. To establish whether any decisions, tribunal determinations, or court judgments have interpreted these Regulations, consult case law databases, tribunal records and recent decisions that address payroll tax, fringe benefit valuation, actuarial determinations or Commissioner directions.

Specific points where litigation might arise

• Determination of whether a contract is within the class prescribed by reg 5, or excluded under reg 6, may be contested where contractual form and reality diverge.

• Disputes about the Commissioner’s exercise of direction powers (for example, directing continuous recording, specifying deemed business kilometres, or directing new actuarial determinations) could give rise to merits review or judicial review claims.

• Challenges could arise concerning valuation of specified taxable benefits where regs 12 and 14 fix value equal to contribution amount and reg 15 exempts wages to the extent recoverable from schemes or funds; factual disputes about recoverability may then engage the Act and these Regulations.

• Record‑keeping disputes and penalties relating to failure to provide documents (including failure to provide an amended FBTA Act assessment within 30 days under r 27) may lead to administrative reviews or litigation over penalty imposition.

Because the Regulations do not include a litigation history section, advisers must check external legal databases and the Commissioner’s published objections and appeals decisions for any authoritative interpretations.

The Regulations contain several technical traps and procedural points that commonly cause compliance errors. Each “gotcha” below is grounded in the relevant regulation.

• Obligations when using motor vehicle allowance averaging method. Employers may only adopt the averaging method if they have used continuous recording for at least 12 consecutive weeks immediately before switching (r 32(3)(a)). They must keep odometer readings at the beginning and end of that continuous recording period and be able to show that journey patterns during the recording period can reasonably be expected to continue for the next five years (r 32(3)(b)-(c)). Failure to comply with those preconditions precludes use of the averaging method and may expose employers to the Commissioner specifying a deemed number of kilometres or accepting zero (r 32(4)).

• Record detail under the continuous recording method. The continuous recording method requires odometer readings at the beginning and end of each business journey, and a record of the purpose of each journey (r 34(a)-(b)). This is operationally demanding where employees make many short trips. Employers must ensure payroll or fleet processes capture the requisite granularity, not simply aggregate odometer changes.

• Retention of records on vehicle replacement. When a vehicle is replaced, the employer must record odometer readings of both vehicles at the time of replacement, record the nomination in writing in the return period in which replacement occurs, and retain all records made under r 37 for five years from the end of the last return period during which allowance relating to journeys before replacement is paid (r 37(2)-(4)). Failure to retain records for the required period can complicate audits.

• Cross‑jurisdictional valuation via the FBTA Act. Several remote location exemptions are expressly conditional on reductions under particular sections of the FBTA Act (rr 9-10). Employers must apply the FBTA Act’s valuation rules and reductions to determine payroll tax exemption. If employers are unfamiliar with the FBTA Act, they may misapply the payroll tax exemptions.

• Actuarial determinations: currency and triggering events. Employers must ensure an actuarial determination is in force where superannuation contributions are taken as wages (r 41(1)). The employer must obtain a new determination as soon as practicable after an event reasonably expected to significantly affect the determination’s accuracy (r 41(2)). The Commissioner may also require a new determination and such directions affect future return periods (r 41(3)-(4)). Employers that neglect to monitor material changes risk producing incorrect payroll tax returns.

• Documentary proof for leave‑related exemptions. Employers claiming exemptions under s 41A(2) for maternity, parental or adoption leave must retain specific documentary proof: medical certificates for maternity leave or statutory declarations for parental/adoption leave (r 46(3A)). Casual or undocumented practices may fail audit scrutiny.

• Electronic lodgement is default. The default mode for lodging returns and paying payroll tax is the Commissioner’s electronic online system and electronic funds transfer methods (r 47(1)). The Commissioner can approve exceptions in writing, but approvals are time‑limited to the first 30 June following the approval (r 47(3)). Employers that cannot meet electronic lodgement requirements must obtain written approval in advance and understand the temporary nature of that approval.

• Effect of Commissioner’s discretionary specifications. Where employers cannot use prescribed methods for calculating business kilometres, the Commissioner may accept an employer’s estimate if considered reasonable, or may specify a deemed number of kilometres, or otherwise treat the number as zero (r 32(4)). This exposes employers to adverse deemed figures if they cannot justify estimates.

• Narrow express penalty. The Regulations include a specific $5,000 penalty only for failure to give the Commissioner a copy of an amended FBT assessment within 30 days (r 27). Practitioners often expect a broader schedule of penalties in the Regulations and may overlook this narrow but significant specific penalty.

• Contract class and exclusions for ship/boat builder procurement. Regulation 5 treats amounts paid under specified procurement contracts as wages; reg 6 provides multiple exclusions, including fixed fee contracts and contracts covered by industrial awards. The legal characterisation of a contract determines payroll tax treatment; misclassification can result in liability or missed deductions.

• Time limits on averaging method durability. The BK percentage established for a vehicle can be used for five years from the end of the continuous recording period unless interrupted by non‑use for 12 consecutive weeks or a Commissioner direction to revert to continuous recording (r 35(4)). Employers assuming indefinite durability of BK percentages risk non‑compliance after five years or when business usage changes.

These procedural and documentary technicalities are concrete compliance risk areas that require systems, processes and professional input to manage. The Regulations prescribe both the measurement methods and the documentary standards that an audit will test.

The Regulations prescribe a set of operational steps employers must follow. Below is a practical, regulation‑rooted compliance checklist for the principal areas covered by the Regulations, with the authoritative provision noted for each action.

Records and documentation (r 46)

• Keep and retain documents evidencing provision of wages or benefits listed in r 46(2): contributions to redundancy schemes (r 46(2)(a)), portable long service leave funds (r 46(2)(b)), value calculations for shares and options taken as wages (r 46(2)(c)), WA fringe benefits (r 46(2)(d)), motor vehicle and accommodation allowances (r 46(2)(e)-(f)), and amounts taken to be wages under s 9CB (r 46(2)(g)).

• If claiming leave‑related exemptions under s 41A(2), obtain and retain required documentation: medical certificates for maternity leave or statutory declarations for parental or adoption leave (r 46(3A)).

• Retain records required under the Regulations for at least five years where specified: for example records after changing from actual value method (r 46(4)) and records relating to vehicle replacement (r 37(4)).

Motor vehicle allowances (rr 30, 32-38; Glossary)

• Decide which method to apply for each vehicle. Use the continuous recording method unless you meet the preconditions for the averaging method (r 32(2)-(3)).

• If using continuous recording, record odometer readings at the beginning and end of each business journey and document each journey’s purpose (r 34(a)-(b)). At the end of each return period, calculate business kilometres using those odometer readings (r 34(c)).

• If you intend to move to the averaging method, complete a continuous recording period of at least 12 consecutive weeks and retain odometer readings at the start and end of that period (r 35(2)(a)-(b), r 36(1)). Use the formula in r 35(2)(c) to establish BK percentage and r 35(3) to calculate average business kilometres in subsequent return periods. Maintain the BK percentage for up to five years unless the conditions in r 35(4) require reversion.

• If replacing a vehicle used for an allowance, nominate the replacement in writing within the return period and record odometer readings for both vehicles at replacement time (r 37(2)-(3)). Keep related records for five years from the end of the last return period during which an allowance relating to journeys before replacement is paid (r 37(4)).

• If an odometer is replaced or recalibrated, record readings immediately before and after the change and account for them when calculating kilometres for the allowance period (r 38).

Actuarial determinations for superannuation contributions (rr 41-45)

• Where s 9CB of the Act takes a superannuation contribution to be wages, ensure an actuarial determination is in force for each relevant return period (r 41(1)). A determination may be made for each member individually or for categories of members (r 42).

• Commission an actuary to produce a determination that specifies contribution amounts for each member or category of member for each return period during the three years after the determination (r 44(1)). If a significant event affects accuracy, obtain a new determination as soon as practicable (r 41(2)). The Commissioner may direct a new determination and such a directive takes effect for return periods commencing after the direction (r 41(3)-(4)).

• Ensure the actuarial determination’s expression of contributions is compatible with operational payroll systems; r 44(4) allows dollar amounts or variables (for example, percentages of salary).

Fringe benefits and remote location exemptions (rr 7-10)

• For remote location fringe benefits, confirm whether the FBTA Act reductions apply and calculate exemption extent accordingly. The Regulations make employer exemption contingent on the FBTA Act’s reduction rules in the specified sections (rr 8-10).

• Where a remote area holiday transport fringe benefit has taxable value reduced under s 60A of the FBTA Act, note that the Regulation provides an exemption equal to twice the amount of that reduction (r 10(5)).

Specified taxable benefits and recoverability (rr 11-15)

• Treat contributions to redundancy benefits schemes and portable long service leave funds as specified taxable benefits and value them as the amount of the contribution (rr 11-14). If an employer is entitled to recover amounts from the scheme or fund, wages provided or payable are exempt to the extent of the amount recoverable (r 15).

Lodgement and payment (r 47; r 48)

• Lodge payroll tax returns and pay payroll tax using the Commissioner’s electronic online systems and approved electronic funds transfer methods unless you obtain a written approval from the Commissioner not to do so (r 47(1)-(2)). Apply in advance for any exception and keep the approval record, noting it expires at the end of the first 30 June following approval (r 47(3)).

• Check whether you qualify for exemption from lodging monthly returns under s 29(1aa)(b) using the prescribed $150,000 amount (r 48).

Reporting amended FBT assessments (r 27)

• If you receive an amended assessment under the FBTA Act, provide a copy to the Commissioner within 30 days of receipt to avoid the $5,000 penalty (r 27).

Administrative interactions and Commissioner directions

• Monitor communications from the Commissioner. The Commissioner may direct you to change vehicle recording methods, specify deemed kilometres, or require new actuarial determinations (rr 32(2)(c), 32(4)(b), 41(3)). Document compliance with any such directions.

Operational controls and systems

• Put in place payroll, fleet and record retention systems that capture odometer start and finish readings, journey purpose, ticketing or invoices supporting remote area exemptions, certificates and statutory declarations for leave exemptions, and copies of any actuarial determinations.

• Engage professionals where required: an actuary for actuarial determinations (r 42-44), tax advisers familiar with FBTA Act valuations for remote area fringe benefits, and payroll systems providers to support the Commissioner’s electronic lodgement requirements.

Record retention and audit readiness

• Keep a compliance file for each tax year showing the method used for vehicle calculations, any BK percentages established and their recording periods, copies of continuous recording logs, actuarial determinations and supporting calculations for contributions treated as wages, and documentation supporting any exemptions claimed.

Following these steps will align operational practice with the Regulations’ prescriptions. Review periodic changes documented in the compilation table and any Commissioner practice statements to ensure continuing compliance, especially where the Commissioner may exercise direction powers or where federal valuation rules under the FBTA Act affect payroll tax treatment.
