Authorised Deposit-taking Institutions Supervisory Levy Imposition Act 1998

The Act operates through a small number of interlinked statutory concepts and defined terms that determine who pays, who decides, how much is payable, and how the cap is adjusted.

• ADI. The Act uses the term ADI and expressly adopts the definition from the Banking Act 1959 (s5). The Act therefore applies to any entity that meets that definition under the Banking Act; the Act does not itself restate the definition.

• Levy components. The payable levy for an ADI in a financial year equals the restricted levy component plus the unrestricted levy component (s7(1)). The restricted component is calculated as the restricted levy percentage of an ADI’s levy base, subject to a floor (minimum restricted levy amount) and a ceiling (maximum restricted levy amount), all of which the Treasurer determines for each financial year (s7(1A), (3)). The unrestricted component is the unrestricted levy percentage of the ADI’s levy base, again with the percentage set by the Treasurer (s7(1B), (3)).

• Levy base. The Act delegates to the Treasurer the method of working out an ADI’s levy base, including the reference day for the levy base (s7(3)(d); s7(5)). The reference day rules in s7(5) set default windows: if an ADI existed continuously from 17 March of the previous financial year to 30 June, the Treasurer must pick a day between that 17 March and the following 14 April; otherwise the levy base is to be worked out as at the day after 17 March on which the ADI became an ADI.

• Levy imposition day. The day on which the imposition takes effect for an ADI in a year is the ADI’s levy imposition day: 1 July for ADIs that are ADIs on that date, or the day in the financial year on which the ADI becomes an ADI (s5). That day drives the pro‑rata calculation where relevant (s7(2)).

• Statutory upper limit and indexation. The Act defines a statutory upper limit that caps the Treasurer’s maximum restricted levy amount. For the financial year commencing 1 July 2020 the statutory upper limit is $10,000,000; for later years it is indexed by multiplying the previous year’s statutory upper limit by an indexation factor (s5 statutory upper limit; s7(4)). The indexation factor is calculated from CPI index numbers and includes a fixed uplift of 0.030 (3 percentage points) added to the CPI change, with prescribed rounding rules to three decimal places (s8).

• Delegated rulemaking. The Act contemplates significant secondary lawmaking: Treasurer determinations to be made by legislative instrument (s7(3)), and regulations for commencement-year modifications (s2(3); s9). The Act does not itself set out procedural detail for the making of those secondary instruments beyond identifying their subject matter.

• Interaction with collection Act. The imposition is declared to be payable in accordance with subsection 8(1) of the Financial Institutions Supervisory Levies Collection Act 1998 (s6). The present Act therefore sets the substantive liability and leaves collection, timing and enforcement to the other statute.

These concepts allocate substantive rulemaking power to the Treasurer, fix certain timing and calculation mechanics in primary legislation, and provide an indexed cap subject to a specific CPI‑derived indexation factor and uplift.

Primary payers. The Act applies to authorised deposit‑taking institutions, adopting the Banking Act 1959 definition of ADI (s5). Any entity that is an ADI under the Banking Act is in the statutory class of liable persons. The Act does not create alternative liability categories; liability is therefore focused on the ADI cohort.

Timing of exposure. An entity’s exposure for a financial year depends on its levy imposition day (s5). If the entity is an ADI on 1 July of a financial year, the levy imposition day is 1 July and the entity is fully subject to that year’s levy regime (s5 levy imposition day). If an entity becomes an ADI later in the financial year, the levy imposition day is the day it becomes an ADI and the Act prescribes a pro‑rata calculation for that year (s7(2)). The statutory mechanics therefore capture both incumbents and entrants, but impose a pro‑rata obligation on entrants within their first partial year.

Who decides amounts. The Treasurer determines the numeric and methodological parameters that fix each ADI’s liability for a given financial year by legislative instrument: the restricted levy percentage, the unrestricted levy percentage, the minimum and maximum restricted levy amounts, and the method for calculating the levy base including the reference day (s7(3)). A Treasurer decision therefore directly affects all ADIs’ obligations.

Geographic scope. The Act binds the Crown in each of its capacities (s3), and extends to each external Territory (s4). Entities operating in external Territories that are ADIs under the Banking Act are therefore within the Act’s territorial reach. The binding of the Crown means that Crown entities that are ADIs would be within the levy net; the Act does not carve out Crown immunity.

Operational actors. The Financial Institutions Supervisory Levies Collection Act 1998 handles collection, because the levy is imposed as payable in accordance with subsection 8(1) of that Act (s6). The collection Act therefore involves administrative actors and mechanisms that ADIs must engage with for payment, although those mechanics are not set out here.

Secondary rule‑makers. The Act empowers the Governor‑General to make regulations for the start‑year modifications required if the Act commences mid‑financial year (s2(3); s9). Those regulations can affect obligations in the commencement financial year for ADIs.

Information sources. The indexation factor depends on CPI index numbers published by the Australian Statistician for specified quarters (s8(1)(a)-(b), (3)(a)). ADIs with multi‑jurisdictional operations must therefore monitor published CPI data and the Treasurer’s timing for determinations.

In sum, the Act targets ADIs as defined in the Banking Act; exposure depends on timing of ADI status; the Treasurer’s subordinate instruments determine most of the numeric parameters; collection is governed by a separate Act; and the Crown and external Territories are caught.

Statutory duties. The Act imposes a duty on ADIs to pay a supervisory levy. The levy payable is the sum of a restricted component and an unrestricted component set out in s7(1) to (1B). The restricted component is the restricted levy percentage applied to the ADI’s levy base, subject to the minimum and maximum restricted levy amounts determined by the Treasurer for each financial year (s7(1A), (3)). The unrestricted component is the unrestricted levy percentage applied to the ADI’s levy base, with the percentage also determined by the Treasurer for each year (s7(1B), (3)). Where an ADI’s levy imposition day is after 1 July in a financial year, the Act provides a specific pro‑rata formula to scale the amount for that financial year (s7(2)).

Payment and collection obligations. The Act declares the levy payable “in accordance with subsection 8(1) of the Financial Institutions Supervisory Levies Collection Act 1998” (s6). That cross‑reference means ADIs must comply with the timing, filing and payment procedures established under the collection Act; those procedural obligations are not reproduced here.

Ministerial rulemaking duties. The Treasurer has a statutory duty to make determinations by legislative instrument regarding: the maximum and minimum restricted levy amounts for each financial year; the restricted levy percentage; the unrestricted levy percentage; and the method for working out an ADI’s levy base including the reference day (s7(3), (5)). Those determinations are mandatory tasks for the Treasurer in each financial year in which levies are to be imposed. Section 7(5) contains specific constraints on the reference day selection, distinguishing ADIs that existed continuously from 17 March to 30 June and those that did not.

Rights and constraints on executive action. The Act limits the Treasurer’s discretion by imposing a statutory upper limit on the maximum restricted levy amount for a financial year (s7(4)). The statutory upper limit is itself specified for 1 July 2020 as $10,000,000 and indexed for later years by the indexation factor provided in s8 and by the statutory upper limit definition in s5. The Treasurer’s determination of the maximum restricted levy amount must not exceed that statutory upper limit (s7(4)). The Act also requires that determinations about the levy base include the timing of the base calculation according to the rules in s7(5), so that the Treasurer cannot select an arbitrary reference date outside those limits for ADIs that meet the continuity condition.

Administrative law implications. Determinations are made by legislative instrument (s7(3)). The Act does not itself spell out review or appeal rights against a determination; the use of a legislative instrument implies that ordinary statutory controls applicable to legislative instruments will apply, but the Act as supplied does not specify those mechanisms or any special review rights for affected ADIs.

Record‑keeping and calculation duties. Because the levy base and the timing of its measurement are specified by Treasurer determinations and s7(5), ADIs will have a practical duty to prepare and maintain the specified records as at the relevant reference day, and to apply the restricted and unrestricted percentages, and minimums and maximums, to those figures.

Commencement‑year modifications. If the Act commences in a financial year but not on 1 July, regulations may be made for modifications to how the Act applies in that financial year (s2(3); s9). This delegates to the Governor‑General the power to alter the Act’s application in the commencement year, which is a potential source of differential treatment in the first year of operation.

Limits on penalties and enforcement in the Act. The Act itself does not set penalties or enforcement procedures; it relies on the collection Act for procedural enforcement. The absence of express penalty provisions in this Act means that enforcement rights and obligations will depend on the content of the collection Act and the Treasurer’s determinations.

Statutory allocation of collection. The Act imposes the levy (s6) but defers the procedural mechanics of collection to the Financial Institutions Supervisory Levies Collection Act 1998 by expressly making the levy payable “in accordance with subsection 8(1)” of that Act (s6). The present text therefore separates substantive liability from enforcement mechanics, and does not itself provide details of time for payment, interest on overdue amounts, penalties, registration or administrative recovery powers.

Absence of penalties in primary text. The Act supplied does not contain provisions that create civil penalties, criminal offences, or express powers to recover unpaid levies in this instrument. The Act also does not prescribe interest, enforcement agencies, distraint powers, charging orders, insolvency consequences, or administrative garnishment powers. Practitioners must accordingly treat the Financial Institutions Supervisory Levies Collection Act 1998 as the necessary source of enforcement mechanisms; the present Act is silent on those modalities (s6).

Role of Treasurer determinations in enforcement context. The Treasurer determines the amounts and percentages which create the formal liability for each ADI (s7(3)). The absence of internal administrative appeal rights or merits review in the present Act means that any mechanisms for dispute about amounts, estimated bases, or eligibility will depend on the collection Act, any public guidance associated with the Treasurer’s legislative instruments, and general administrative law principles outside the present text. The Act does require that the Treasurer’s determination of the maximum restricted levy amount not exceed the statutory upper limit (s7(4)), but it does not provide a private right to challenge a Treasurer determination within the Act itself.

Compliance risk and timing. Because the indexation factor uses CPI numbers published up to the most recent quarter as at the start of the day the Treasurer makes the first determination for the financial year (s8(1)(a)), timing of the Treasurer’s first determination has a direct effect on the calculated indexation factor and therefore on the statutory upper limit cap (s8(1)(a); s5 statutory upper limit). Timely publication of the Treasurer’s legislative instruments will therefore affect ADIs’ ability to predict their liability and to plan payment in accordance with collection processes in the collection Act.

Territorial and Crown enforcement. The Act binds the Crown (s3) and extends to external Territories (s4). The binding of the Crown means that if the Crown or a Crown entity meets the ADI definition, then the levy regime applies to them; the Act does not provide special Crown immunity or enforcement carve‑outs. How enforcement against Crown entities would proceed is not addressed in this Act.

Regulatory and criminal enforcement outside the Act. The Act’s silence on enforcement mechanisms does not prevent other statutes or regulatory regimes from imposing sanctions related to failure to pay levies, but any such interaction would fall outside the scope of the supplied text and must be located in the collection Act or other relevant statutes.

Direct references to other statutes. The Act incorporates or cross‑refers to several external legal instruments. It defines ADI by reference to the Banking Act 1959 (s5), it makes the levy payable according to subsection 8(1) of the Financial Institutions Supervisory Levies Collection Act 1998 (s6), and it requires CPI index numbers published by the Australian Statistician for indexation calculations (s8(1)(a), (3)). Those references mean that the reach, definition and procedural aspects of the levy are guided by the content of those external instruments.

Delegation and subordinate law. The Act vests significant subordinate lawmaking authority in the Treasurer by requiring determinations “by legislative instrument” for multiple variables (s7(3)). Those instruments will sit within the framework of federal legislative instruments and will interact with the legislative instrument regime and any applicable disallowance, tabling or transparency requirements that arise under the Acts Interpretation Act or other statutes. The Act itself does not restate those procedural constraints; it simply prescribes the content of instruments to be made by the Treasurer.

Collection Act dependency. The Act’s statement that the levy is payable “in accordance with subsection 8(1) of the Financial Institutions Supervisory Levies Collection Act 1998” (s6) delegates collection, payment timing, notice requirements, and likely enforcement measures to that Act. The two statutes operate as companion provisions: this Act creates the liability and the collection Act supplies the mechanisms to collect it. Any obligations relating to notices, deadlines, adjustments, enforcement, dispute resolution about liability, or recovery will therefore be found in the collection Act rather than in this Act.

Regulatory instruments for commencement modifications. Section 2(3) permits the Act to have effect in a financial year with modifications specified in regulations if the Act commences during a financial year but not on 1 July. The Governor‑General may make regulations for that purpose (s9). The interaction here is with the regulations power, enabling the executive to tailor the Act’s operation for first‑year implementation effects; those rules will interact with the Treasurer’s legislative instruments to determine practical application in the commencement year.

Indexation and statistical data. The indexation factor is computed from CPI index numbers published by the Australian Statistician (s8(1)(a), (3)). The Act thereby depends on the Australian Statistician’s CPI publications and their timing. Section 8(3) restricts calculation to index numbers published under the most recently published index reference period, and disregards replacement indices except in cases where the replacement takes account of changes in reference period. This interacts with any changes the Australian Statistician may adopt in reference periods and with how substituted CPI numbers are administered.

Crown and external Territories. The Act binds the Crown (s3) and extends to external Territories (s4). These provisions ensure that other Commonwealth statutes and obligations that apply to the Crown or to territories will need to be read alongside this Act if an entity is an ADI. The Act does not remove or modify other liability regimes, but subjects Crown ADIs and ADIs in external Territories to the levy regime as written.

Administrative law. Decisions under the Act (e.g. legislative instruments by the Treasurer) are administrative acts. The Act does not itself create internal merits review or appeal channels against those instruments; general administrative law remedies and judicial review could apply to decisions taken under the Act, but those remedies and their availability are not addressed in the text supplied.

In sum, the Act is structured to work in tandem with the Banking Act 1959 for definitional scope, with the Financial Institutions Supervisory Levies Collection Act 1998 for collection and enforcement, with the Australian Statistician’s CPI publications for indexation, and with the legislative instrument and regulations regime for detail and commencement‑year modifications.

The text supplied does not include an express legislative amendment schedule or a formal history of amendments. The Act as presented contains provisions that fix certain figures and set indexation rules; these provisions are within the Act’s body rather than a schedule of amending instruments in the supplied text. Notable internal content that affects inter‑year change without requiring amendment of the principal Act is the statutory upper limit and its indexation mechanism.

• Statutory upper limit. The Act defines a statutory upper limit that is fixed for the financial year commencing 1 July 2020 at $10,000,000, and for later financial years is calculated by multiplying the statutory upper limit for the previous financial year by the indexation factor for the later financial year (s5 statutory upper limit). The presence of a specific dollar amount for 1 July 2020 is part of the current text; the Act then provides a formulaic, automatic mechanism to move that limit forward year to year without requiring a primary legislation amendment.

• Indexation mechanics. Section 8 prescribes the indexation factor calculation: it uses a CPI change over 12 months based on the most recent quarter for which CPI is published at the start of the day when the Treasurer makes the first determination for the financial year, and then adds 0.030 (3 percentage points) to that change. It also prescribes rounding to three decimal places with a rounding‑up rule if the fourth decimal place is more than 4, and specifies which CPI index numbers are to be used (s8(1)-(3)). These mechanistic rules are embedded in the Act and will produce automatic annual changes in the statutory upper limit without primary amendment.

• Delegation of numeric setting. The Act delegates to the Treasurer the power, by legislative instrument, to fix the restricted and unrestricted percentages, and the minimum and maximum restricted levy amounts, each financial year (s7(3)). That design minimises the need to amend primary legislation for year‑to‑year numeric changes and instead relies on subordinate instruments.

• Commencement contingencies. Section 2 contains a backstop automatic commencement rule if the Act is not proclaimed within 24 months of Royal Assent (s2(2)), and allows for regulations to modify the Act’s operation if the Act commences in a financial year but not on 1 July (s2(3); s9). Those provisions address constitutional practicalities of commencement, and permit regulation‑making to handle transitional matters in the first year.

Because the supplied text does not contain a historical log of enacted amendments, users seeking the legislative amendment record, such as dates of amendments, text changed, or historical versions, will need to consult an authoritative legislative history source. The Act itself, however, embeds mechanisms (indexation and Treasurer determinations) that reduce the frequency with which primary amendment is likely to be needed for routine numeric adjustments.

The supplied Act text contains no references to case law, court decisions, or litigation outcomes. There are no schedules or notes within the text that record judicial interpretation, declaratory judgments, or contested applications of the Act. The Act sets out legal mechanics and delegations but does not include any statutory provision describing remedies or rights of appeal specific to determinations made under it.

Given that the Act delegates considerable discretion to the Treasurer via legislative instruments (s7(3)) and relies on another statute for collection and enforcement (s6), any litigation relating to the operation of this regime would likely arise in respect of:

• challenges to Treasurer determinations made by legislative instrument, including procedural or jurisdictional grounds, or the ambit of the Treasurer’s power under s7(3);

• disputes about the levy base methodology as implemented under the Treasurer’s determinations, including how the levy base reference day is selected under s7(5);

• challenges connected to indexation calculations under s8, particularly where timing of determinations affects the “most recent quarter” used in s8(1)(a);

• disputes arising from procedures in the Financial Institutions Supervisory Levies Collection Act 1998 applied to collection, enforcement, interest and penalties, as the present Act defers enforcement mechanics to that statute (s6).

However, none of those litigation themes are documented in or confirmed by the text supplied. The Act does not carve out special judicial review procedures, nor does it refer to any tribunal jurisdiction. Practitioners interested in litigation history will therefore need to consult court records and decision repositories to identify any cases that involve the application or interpretation of this Act or of the Treasurer’s subordinate instruments made under it.

The absence of litigation notes in the Act’s text does not imply an absence of legal disputes in practice, but the primary instrument provided here contains no record, and does not constrain or prescribe litigation remedies specific to this Act beyond the ordinary legal framework.

Several practical traps and operational frictions emerge directly from the text of the Act. These are concrete mechanics that can create uncertainty or additional administrative work for ADIs and their advisers.

1. Heavy reliance on Treasurer determinations. The core numeric parameters are not set in the Act but are to be fixed annually by legislative instrument: restricted/unrestricted percentages, and minimum/maximum restricted levy amounts (s7(3)). This produces year‑to‑year uncertainty until the instrument is published; ADIs cannot know their levy exposure for a year until those determinations are made public.

2. Statutory cap mechanics and indexation timing. The statutory upper limit for the maximum restricted levy amount is indexed by an indexation factor that depends on the CPI quarter “as at the start of the day on which the Treasurer makes the first determination under subsection 7(3) of an amount or percentage for the financial year” (s8(1)(a)). The indexation factor also adds a 0.030 uplift (s8(1)(c)). The timing of the Treasurer’s first determination therefore alters which CPI quarter is the “most recent quarter” and so affects the indexation. It creates a tactical interaction between the timing of Treasurer action and the effective statutory upper limit.

3. Fixed uplift in indexation factor. The indexation factor adds 0.030 (i.e. 3 percentage points) to the CPI change (s8(1)(c)). That is not a pure CPI link; it guarantees an extra uplift in the statutory upper limit beyond CPI increases. Entities forecasting exposure must model that uplift.

4. Reference day complexity for levy base. The Treasurer’s determination of “how an ADI’s levy base is to be worked out” must include a day as at which the levy base is measured, but s7(5) constrains that day depending on whether the ADI existed continuously from 17 March to 30 June of the prior financial year. The rule differentiates incumbent ADIs and more recent entrants (s7(5)(a)-(b)). Small differences in corporate events around 17 March (e.g. mergers, authorisation dates) can change which part of s7(5) applies and therefore the reference day, with potentially material levy consequences.

5. Pro‑rata formula for part‑year ADIs. If the levy imposition day is later than 1 July, s7(2) prescribes a formula to scale the levy for the part year. The formula depends on the levy imposition day and on the annual amount that would otherwise be payable. Operationally, ADIs that become ADIs mid‑year must ensure accurate record‑keeping to apply the formula.

6. Delegated floor and ceiling. The restricted levy component is subject to a floor and a ceiling determined by the Treasurer (s7(1A), (3)). The maximum restricted levy amount is further capped by the statutory upper limit (s7(4)). Those overlapping caps, floors and percentages can produce non‑linear effects on marginal levy incidence. For example, increases in an ADI’s levy base may not translate into higher restricted levies if the cap is binding.

7. Dependence on collection Act for enforcement. Enforcement, penalties and payment mechanisms are not set out in this Act; they derive from the Financial Institutions Supervisory Levies Collection Act 1998 (s6). ADIs must therefore coordinate compliance with two statutes and cannot find enforcement detail here.

8. No bespoke appeal or review provisions in the Act. The Act is silent on merits review or internal appeal against Treasurer determinations, calculation of levy base, or levies imposed, potentially increasing reliance on general administrative law remedies and external litigation, with attendant cost and uncertainty.

9. Commencement‑year adjustments by regulation. If the Act commences during a financial year and not on 1 July, the Governor‑General may make regulations modifying the Act’s effect for that financial year (s2(3); s9). That introduces a potential one‑off variation in treatment in the commencement year that may create transitional complexity for ADIs affected.

10. Binding the Crown and external Territories. The Act binds the Crown (s3) and extends to external Territories (s4). Entities with complex ownership structures involving Crown entities or operations in external Territories should not assume exclusion from the levy net.

These elements require ADIs and advisers to track Treasurer instruments, CPI publications, and the collection Act closely, and to maintain precise records for the relevant levy base reference day and for any corporate status changes around 17 March.

Practical compliance under this Act requires operational monitoring, accurate record keeping as at specified dates, and coordination with the Treasurer’s instruments and the collection Act. The steps below set out a practical compliance checklist based solely on the Act’s text.

1. Confirm ADI status. Establish whether the entity is an ADI as defined in the Banking Act 1959 (s5). If status is uncertain, verify the entity’s accreditation date under the Banking Act, because that date determines levy imposition day and potential pro‑rata treatment (s5 levy imposition day; s7(2)).

2. Monitor Treasurer legislative instruments. The Treasurer will determine annually, by legislative instrument, the restricted levy percentage, the unrestricted levy percentage, the maximum and minimum restricted levy amounts, and how the levy base is to be worked out (s7(3)). Ensure a process to detect publication of these instruments promptly, because they fix the numeric parameters for the financial year.

3. Determine levy imposition day. Record whether the entity was an ADI on 1 July of the financial year; if so, the levy imposition day is 1 July (s5). If the entity became an ADI after 1 July, note the date it became an ADI, because s7(2) prescribes a pro‑rata formula using the levy imposition day.

4. Identify levy base reference day. The Treasurer’s determination of how the levy base is worked out must include a reference day (s7(3)(d); s7(5)). Apply s7(5) rules to determine the reference day window: if the ADI existed continuously from 17 March of the previous financial year to 30 June, the reference day must be between 17 March and the following 14 April; otherwise the reference day is the day after 17 March when the ADI became an ADI (s7(5)). Maintain records and data snapshots for the reference day specified.

5. Compute the levy base. Using the method set by the Treasurer, calculate the levy base as at the reference day. The Act leaves the detailed method to the Treasurer; ensure your internal accounting and reporting systems can provide the specified metrics as at the nominated date.

6. Calculate restricted and unrestricted components. Apply the restricted levy percentage to the levy base to compute the prima facie restricted levy component, then apply the minimum and maximum restricted levy amounts determined by the Treasurer for the financial year to ensure the component is within the statutory floor and ceiling (s7(1A), (3)). Separately apply the unrestricted levy percentage to the levy base to compute the unrestricted component (s7(1B), (3)). Sum the two components to arrive at the annual levy amount (s7(1)).

7. Apply pro‑rata formula if relevant. If the levy imposition day is later than 1 July, apply the pro‑rata calculation provided in s7(2) to scale the annual amount to the part year. Ensure accurate day counts and calendar arithmetic when applying the formula.

8. Track indexation for statutory upper limit. If the Treasurer’s maximum restricted levy amount approaches the statutory upper limit, be aware the limit for years after 2020 is multiplied by the indexation factor calculated under s8. Note that s8 uses CPI quarters as at the start of the day the Treasurer makes the first determination for the year and adds 0.030 to the CPI change; maintain awareness of CPI release dates and the Treasurer’s timeline (s5 statutory upper limit; s8(1)(a)-(c)).

9. Coordinate with collection Act obligations. The levy is payable in accordance with subsection 8(1) of the Financial Institutions Supervisory Levies Collection Act 1998 (s6). Confirm payment dates, invoicing, remittance methods, and any reporting or certification required by the collection Act. Keep records demonstrating timely payment in accordance with the collection Act.

10. Prepare for regulatory or transitional modifications. If the Act commences during a financial year and not on 1 July, regulations may modify its application for that year (s2(3); s9). Be ready to implement modifications specified by regulations affecting the commencement financial year.

11. Record keeping and audit trail. Retain contemporaneous records as at the levy base reference day, records of ADI status changes around 17 March, and copies of the Treasurer’s legislative instruments and any relevant regulations. Keep documentation that supports calculations in case of queries or audits.

12. Legal and administrative review. Because the Act delegates substantive settings to the Treasurer and defers collection to another Act, set up legal review checkpoints when legislative instruments are published, to assess whether the Treasurer’s determinations are within the Act’s constraints (for example the maximum restricted levy amount must not exceed the statutory upper limit, s7(4)). Consider whether administrative review or judicial avenues are needed if a determination appears inconsistent with the Act.

13. Internal forecasting. Model levy exposure under different Treasurer determination scenarios and be explicit about the effects of the indexation factor’s 3 percentage point uplift and rounding rules (s8(1)(c); s8(2)). This assists budgeting and capital planning.

14. Consider corporate events timing. Transactions, restructures, mergers or disposals that affect ADI status around 17 March should be planned with the reference day and levy imposition rules in mind, because they can alter which calculation path in s7(5) applies and therefore the levy base and imposition timing.

Following the steps above will align an ADI’s internal controls with the statutory mechanics in this Act. Because enforcement and procedural detail are in the separate collection Act, coordination with the collection Act’s requirements is necessary to complete the compliance picture.
