Taxation (Interest on Overpayments and Early Payments) Regulations 2018

The central concept is “correlative relief”, defined in section 3A of the Act as a right to interest when a DTA provision is applied in a manner that adjusts profits of a permanent establishment, requiring a compensating adjustment in the other Contracting State. The Regulations merely prescribe which applications of which Articles trigger that right. Two forms of double taxation are addressed. “Juridical double taxation” arises when the same income is taxed in both States because each treats the permanent establishment’s profits differently. “Economic double taxation” arises when related enterprises in two States have their profits adjusted (e.g. under transfer pricing rules) and no compensating adjustment is made in the other State; regulation 7 uses the Vietnam agreement’s Article 9(3) as the prescribed standard for that situation. A key distinction lies in the two types of Article 7 provisions. The table in regulation 6(3) covers DTAs that follow the OECD Model Convention’s standard Article 7, which limits attribution to profits actually derived through the permanent establishment. The table in regulation 6(5) covers nine DTAs (Argentina, Fiji, Indonesia, Kiribati, Mexico, Papua New Guinea, Philippines, Sri Lanka, Thailand) whose Article 7 includes a “force of attraction” rule: if the resident carries on business activities in the other State that are similar to those conducted through the permanent establishment, profits from those activities are also attributed to the permanent establishment. This broader attribution enlarges the pool of profits that can trigger correlative relief. The term “primary foreign country” from section 3A(2) of the Act means a country with which Australia has no DTA. Regulations 7 and 8 use that concept but then prescribe provisions of the Vietnam agreement as the operative standard, which is a curious drafting technique: they create a notional provision derived from an actual DTA to fill the gap where no DTA exists. This imposes a uniform default rule for all such no‑DTA countries, rather than leaving the matter open. The Regulations also define “resident of Australia” and “taxpayer” by reference to the Income Tax Assessment Act 1936, and “permanent establishment” and “Contracting State” by reference to the International Tax Agreements Act 1953. Because these definitions are incorporated by reference, any amendment to those Acts automatically affects the scope of these Regulations without any amending instrument. That is a notable delegation of legislative power.

The Regulations directly affect taxpayers who have a permanent establishment in a Contracting State and whose profits have been adjusted by a tax authority in a manner that falls within the prescribed provisions. This includes Australian residents with outward permanent establishments in any of the 44 listed countries, and non-residents with inward permanent establishments in Australia. The practical impact is on multinational enterprises, particularly those operating through branches or offices in treaty countries. The split between the standard Article 7 list and the force-of-attraction list means that taxpayers in the nine countries with the broader rule (Argentina, Fiji, Indonesia, Kiribati, Mexico, Papua New Guinea, Philippines, Sri Lanka, Thailand) have a wider pool of profits that can generate correlative relief. That could be beneficial if their sales or similar business activities are subject to attribution under the DTA, but it also introduces greater uncertainty because the force-of-attraction rule is applied to a wider set of facts. For taxpayers operating in countries with which Australia has no DTA, the Regulations apply a default prescribed method using the Vietnam agreement provisions. This only helps if the foreign country is a “primary foreign country” meaning no DTA is in force. The Commissioner of Taxation is indirectly affected because these Regulations define when the Act’s interest obligation arises: if a prescribed provision has been applied in the described manner, the Commissioner must treat the adjustment as giving rise to an overpayment and pay interest under the Act. Tax practitioners, accountants and in-house tax lawyers need to be familiar with which DTA is in force for a given country and which list (standard or force-of-attraction) applies. The Regulations also affect the ATO’s compliance and refund systems, as they determine when interest must be calculated and paid. The retrospective operation in regulation 9(2) adds a further compliance dimension: for income derived before 15 September 2018, practitioners must check whether the relevant DTA was then in force and whether it was listed in the 1992 Regulations. If not, the 2018 Regulations now cover that period, potentially entitling the taxpayer to interest that was not previously available. That creates a need to review historic adjustments for pre-2018 years.

The Regulations do not impose duties directly; they are enabling provisions that trigger a right to interest under the Act. The key right is the taxpayer’s entitlement to have an overpayment treated as having arisen under section 3A of the Act when a prescribed DTA provision is applied in the specified manner. That right is valuable because interest on overpayments is payable by the Commissioner at the rate set under the Act, which can be significant for large adjustments spanning multiple years. The duty falls on the Commissioner to pay that interest once the prescribed condition is satisfied. The Regulations themselves do not create a duty on the taxpayer to apply for relief or to provide information, but in practice the taxpayer must demonstrate that the DTA provision has been applied in the prescribed manner. The manner of operation is defined purely by reference to whether the application of the provision increases or decreases profits attributable to a permanent establishment (or, in the force-of-attraction list, also profits from sales of similar goods or similar business activities). The taxpayer has the right to rely on the Regulations to claim interest, but the burden of proof that the adjustment falls within the prescribed description rests with the taxpayer. There is no duty on the tax authority of the other Contracting State to make a correlative adjustment; the Regulations only address the Australian side. If the foreign adjustment is not followed by a corresponding Australian adjustment, the taxpayer might have a right to interest on the Australian tax overpaid as a result of the double tax relief mechanism. Note that the Regulations do not address the situation where the DTA provision is applied in a manner that decreases profits for a non-resident or increases profits for a resident - those are the mirror situations prescribed in regulations 6(1)(b) and 6(1)(a) and 6(4)(b) and 6(4)(a). The right to interest therefore runs both ways, depending on which side of the border the taxpayer sits. However, the Regulations do not confer any discretion: if the prescribed condition is met, the Act’s operation is triggered.

The Regulations themselves contain no penalty provisions. Enforcement of the interest obligation is a matter for the Act, which sets out how interest on overpayments is calculated and paid. If the Commissioner fails to pay interest when a prescribed provision has been applied in the required manner, the taxpayer may seek review or appeal under the taxation objection and appeal provisions. There is no penalty for a taxpayer who incorrectly claims relief, other than the normal shortfall interest charge and potential administrative penalties under the Taxation Administration Act 1953 if the claim is made recklessly or fraudulently. The lack of penalties in the Regulations is unsurprising because they merely operationalise the Act. However, the practical enforcement risk lies in the Commissioner taking a narrow view of what constitutes “applied in a manner which increases the profits … attributable to a permanent establishment”. If the Commissioner disputes that the adjustment falls within the prescribed manner, the taxpayer may need to litigate. The Regulations give no guidance on how to measure the increase or decrease in profits; that remains a factual question under the relevant DTA article. The force-of-attraction provisions in regulation 6(4) may be particularly contested because they require establishing that sales or business activities are “of the same or similar kind” as those carried on through the permanent establishment. That is a vague standard that invites disagreement. Taxpayers who rely on the broader head of relief bear the risk of an adverse ruling and potential costs. There is also an indirect enforcement dimension: the Regulations effectively create an entitlement to interest that the government must fund. If the Commissioner resists payment, the taxpayer’s only remedy is to pursue the matter through the courts. The Regulations provide no alternative dispute resolution or deeming provisions.

The Regulations sit entirely within the framework of the Taxation (Interest on Overpayments and Early Payments) Act 1983. They prescribe matters “for the purposes of paragraph 3A(1)(b)” and “for the purposes of paragraph 3A(2)(b)” of that Act. That means they are subordinate legislation that gives content to the primary law’s concept of “manner of operation” of DTA provisions. If the primary Act were amended, these Regulations would need to be updated or would become obsolete. The Regulations also interact heavily with the International Tax Agreements Act 1953. They adopt definitions from section 3(12) of that Act for “Contracting State” and “permanent establishment”. Furthermore, they refer to DTAs by the names listed in sections 3AAA or 3AAB of that Act. Any change to those listing provisions (a new DTA, a termination, or a protocol) would not automatically update the Regulations; a new regulation would be required to add or remove an entry. The incorporation by reference to the Income Tax Assessment Act 1936 for the definition of “taxpayer” means that if that definition changes, the scope of who can claim correlative relief shifts automatically. This is a delegation of legislative power that could have unintended effects. The Regulations also repeal and replace the earlier 1992 Regulations. Transitional regulation 9(3) preserves the effect of the 1992 Regulations for income derived before 15 September 2018 in respect of DTAs that were already covered by them. This avoids a retroactive loss of rights but creates a dual system: practitioners must apply the 1992 Regulations for older periods where the DTA was listed, and the 2018 Regulations for later periods or for DTAs newly listed. The force-of-attraction list in regulation 6(5) has no equivalent in the 1992 Regulations; that list is entirely new. The Regulations do not interact with state or territory laws. They are purely Commonwealth tax regulations. They do not affect the Taxation Administration Act 1953 directly, but the interest paid under the Act (triggered by these Regulations) will be assessable or deductible depending on the taxpayer’s circumstances. The Regulations also do not interact with the Corporations Act or other commercial legislation, except insofar as they affect a company’s tax position and thus its financial statements.

The instrument was made on 13 September 2018 and took effect on 15 September 2018 (the day after registration). It has not been amended. The text provided shows no subsequent amendments. The original 1992 Regulations that it repeals had been in force for over 25 years. The 2018 Regulations were not made to change substance dramatically but rather to update the list of DTAs and to restructure the instrument. The major substantive change is the addition of the force-of-attraction table in regulation 6(5) for nine DTAs. The 1992 Regulations had only a single list of Article 7 provisions for all DTAs. The 2018 Regulations also introduced the use of the Vietnam agreement as the default for no‑DTA countries (regulations 7 and 8) - a concept not present in the 1992 Regulations. Another change is the inclusion of a transitional provision (regulation 9) that preserves the old regime for pre‑2018 income where the DTA was already covered. That transitional provision was necessary to avoid taxpayers losing existing entitlements. Because the instrument is a legislative instrument made under the Act, it is subject to disallowance by either House of Parliament, but there is no record of disallowance. The amendment history is therefore limited to its making and commencement. Any future amendment would be required to add new DTAs (such as those with the United Kingdom after Brexit or new treaties) or to remove terminated agreements. The lack of amendment history does not suggest stability; it merely indicates that the list of DTAs has not changed since 2018 in a way that required regulatory amendment. Practitioners must check whether any later amending instruments exist because the published text here is only the original.

There is no reference to any litigation in the instrument itself. The Regulations have not been the subject of reported court decisions. That is not surprising: regulations of this type are rarely litigated directly. Instead, disputes about correlative relief typically arise under the relevant DTA article or under section 3A of the Act. The Regulations merely prescribe the manner of operation, so any challenge would likely be to the Commissioner’s refusal to pay interest on the basis that the DTA provision was not applied in the prescribed manner. The lack of litigation history means there is no judicial guidance on key interpretive questions: what does “applied in a manner which increases the profits … attributable to a permanent establishment” mean? Does it require a formal adjustment notice, or can it be a de facto application of the article? The force-of-attraction phrase “same or similar kind” is also untested in this context. Because the Regulations are relatively new (2018), and because correlative relief cases are infrequent, it may take years before a court interprets these provisions. Taxpayers should be aware that the absence of caselaw creates legal risk: the ATO may take a restrictive view, and the taxpayer would have to fund litigation to resolve it. The force-of-attraction provisions in particular involve nine DTAs that may operate differently in practice. The use of the Vietnam agreement as a default for no‑DTA countries (regulations 7 and 8) is also untested. In principle, a taxpayer might argue that the prescribed manner does not apply because the foreign country is not Vietnam, but the regulations deliberately use those articles as a proxy. That drafting choice could be challenged as ultra vires if it goes beyond the Act’s delegation, but no court has considered this. Overall, the litigation history is a blank slate, which is neither good nor bad but does counsel caution.

Several traps await the unwary. First, the force-of-attraction list in regulation 6(5) is easy to overlook because it appears in a separate subsection and table. A practitioner working with a taxpayer in one of those nine countries might assume the standard Article 7 rule applies, missing the broader attribution that could either benefit the taxpayer (more profits eligible for relief) or create a risk that the ATO uses the force-of-attraction rule to deny relief if the taxpayer fails to demonstrate similarity of sales. Second, the definitions cross-reference to other Acts that may change without notice. For example, the definition of “resident of Australia” from the Income Tax Assessment Act 1936 has been the subject of legislative amendments (such as the modernisation of the corporate residency test). A change in the definition could expand or contract the class of taxpayers who qualify as residents for these Regulations, without any amendment to the Regulations themselves. Third, the transitional provisions in regulation 9 create a dual regime. For income derived before 15 September 2018, you must check both whether the DTA was in force at that time and whether the 1992 Regulations covered it. A DTA that was in force pre-2018 but not listed in the 1992 Regulations is now covered by the 2018 Regulations under regulation 9(2). That means a taxpayer who was denied interest under the old regime might now have a valid claim for the pre-2018 period. Fourth, the use of the Vietnam agreement as the default for no‑DTA countries in regulations 7 and 8 is unusual. The Act refers to a “primary foreign country” (a country with no DTA), but the Regulations prescribe a specific DTA article as the standard. That might be legally valid, but it creates a fiction: the taxpayer must show that Article 7 of the Vietnam agreement has been applied in a manner that increases or decreases profits attributable to a permanent establishment in that primary foreign country. It is unclear how the Commissioner will treat a request for relief under that provision when no Vietnam agreement applies to the foreign country. The regulation may be interpreted as using the Vietnam wording as a template rather than requiring the actual application of that treaty. Fifth, the phrase “applied in a manner” is ambiguous. It could mean that the tax authority of the other Contracting State applied the DTA provision in its assessment. But the taxpayer may not have a formal assessment from that foreign authority; the taxpayer might self-assess under the DTA. The regulations do not clarify this. Sixth, the instrument does not address the rate of interest or the period for which it is payable; that is left to the Act. Practitioners must read the Act and any determinations made under it separately.

Compliance is passive for the taxpayer in the sense that the Regulations do not require any filing or reporting. However, to benefit from the interest entitlement, the taxpayer must be able to demonstrate that the prescribed condition is satisfied. The practical steps are these. First, identify whether the taxpayer has a permanent establishment in a Contracting State listed in either table. Check the 35 DTAs in regulation 6(3) (standard Article 7) and the nine DTAs in regulation 6(5) (force-of-attraction). Note that Singapore is under regulation 6(3) with Article 5 (Singapore uses a different article number). Second, determine whether the foreign tax authority or the taxpayer (under self-assessment) has applied the relevant DTA article in a manner that increases or decreases the profits attributable to the permanent establishment. If the taxpayer is an Australian resident, they need an increase in profits of the PE in the other State; if a non-resident, a decrease in profits of the PE in Australia. For the force-of-attraction DTAs, also check whether sales of similar goods or similar business activities are involved. Third, if there is no DTA with the foreign country, check if it qualifies as a “primary foreign country” under the Act. If so, the prescribed provisions are Article 9(3) of the Vietnam agreement for economic double taxation and Article 7 of that agreement for juridical double taxation. The taxpayer must be able to show that the foreign adjustment falls within the manner described in those articles. Fourth, keep contemporaneous records of the foreign tax assessment or the self-assessment basis, including any correspondence with the foreign tax authority. The Commissioner may request evidence that the DTA provision was actually “applied” in the relevant manner. Fifth, for historic periods (pre-15 September 2018), check whether the 1992 Regulations covered the DTA at the time. If not, the 2018 Regulations may now apply retroactively. Sixth, file an objection or amendment request under the Act if the Commissioner has not paid interest on the overpayment that results from the correlative relief. The entitlement to interest arises automatically if the condition is met, but in practice the Commissioner may not pay until the taxpayer claims it. Seventh, monitor changes to the list of DTAs or to the definitions in the International Tax Agreements Act 1953 and Income Tax Assessment Act 1936, as those changes may affect eligibility without any amendment to these Regulations. Finally, seek professional advice because the Regulations are dense and cross-reference multiple other instruments. The absence of litigation history means there is no settled guidance on many interpretive issues.
