Simplifying the Flat Rate Tax Credit System - In Time For Our First Year End Reporting?

Angela Hodges • 29 September 2024

How Upcoming Tax Changes Could Streamline Reporting for Short-Stay Accommodation Providers

When we presented on the new flat rate tax credit system earlier this year, we quickly worked out the income tax implications were going to be complicated – and costly for clients. 


For income tax purposes, the flat-rate GST credit for non-GST registered suppliers of short-stay accommodation, such as those using platforms like Airbnb, was treated as excluded income for income tax purposes. 

While this approach provided a simplified treatment on the income side, it led to considerable complexity when it came to expense deductions. Suppliers were required to apportion their expenses between GST-exclusive and GST-inclusive costs, depending on how their income was earned.


Income Tax Treatment of the Flat-Rate Credit:

Under the current rules, the flat-rate GST credit received by non-registered suppliers is excluded income for income tax purposes. This means that any expenses incurred in relation to this income have to be treated accordingly.


For suppliers who rented their property both through online platforms and privately, this meant that costs such as cleaning, maintenance, and utilities had to be apportioned based on how the property was used. This apportionment could be complex and time-consuming, as suppliers needed to calculate which expenses applied to online marketplace bookings and which applied to other types of bookings.


Specifically:

  • Marketplace rentals: Expenses associated with nights rented via an online marketplace were deductible on a GST-exclusive basis. E.g. expenses related to AirBnB bookings.
  • Non-marketplace rentals: Expenses associated with other rental nights were deductible on a GST-inclusive basis, as no flat-rate credit applied. E.g. expenses related to bookings directly from the supplier’s own website.


When expenses were shared across both types of rental nights, suppliers had to allocate or apportion their expenses proportionally, adding a layer of complexity to their year-end tax filings.


A New Option:

To simplify this process, the Taxation (Annual Rates for 2024–2025, Emergency Response, and Remedial Measures) Bill proposes an amendment that would allow non-registered suppliers to treat the flat-rate GST credit as assessable income for income tax purposes. 


If a supplier elects this option, they will no longer need to apportion their costs. Instead, all expenses related to short-stay accommodation, including those booked through online platforms, can be deducted on a GST-inclusive basis. It eliminates the need to apportion costs, which many short-stay providers and advisors found difficult and confusing.

If enacted, this proposal will remove the need for apportionment and allow for more straightforward tax filings. Draft rulings have already been prepared by Inland Revenue based on the assumption that this amendment will be passed into law.  


Why This Sounds Familiar:

The proposed approach bears a strong resemblance to our original discussions to treat the flat-rate GST credit as a negative expense. This suggestion was based on the understanding that the flat-rate credit serves as a pseudo-GST component, reflecting the portion of expenses related to the supply on which GST is effectively being paid. By treating it as a negative expense for income tax purposes, or now as assessable income, it should align the GST component of income and expenses, making tax reporting much simpler for non-registered suppliers.


This treatment is optional, and some taxpayers may prefer to treat the flat rate tax credit as non-assessable income and complete any apportionment of expenses required.  


My Perspective:

Had these changes not been introduced, many short-stay accommodation providers might have struggled to comply with the existing rules. The cost and effort involved in meeting the detailed requirements for apportioning expenses would have been a significant burden, particularly for smaller operators. This simplification is a practical solution. By making the system easier to navigate, it increases the likelihood that providers will comply with the new flat rate tax credit rules.

The recently introduced Tax Bill includes significant tax changes for remote workers, including surprising tax reforms granting digital nomads a brand-new tax concession intended to reflect the visitor visa conditions. A New Tax Exemption for “Non Resident Visitors” Currently the NZ tax residency rules are not aligned with immigration visa conditions, which has led to unexpected tax consequences for many visitors. Individuals who spend 183 days or more in NZ may be deemed tax resident from the first day of their stay. Likewise, salary earned from a non-resident employer could be taxable in NZ, without a foreign tax credit recognising tax paid offshore. We have worked with many individuals who have had significant and unexpected tax liabilities because of these rules. The Proposal A pivotal change is the introduction of a new “non-resident visitor” tax status which will provide an exemption from the 183-day test. Under the proposed law, individuals who meet the following requirements should not become NZ tax residents, despite their extended stay: • are in NZ for 275 days or fewer within any 18 month period, • were not NZ tax residents or transitional residents immediately before arrival, • are lawfully present, • are not receiving a family scheme entitlement, and • remain tax residents of a foreign jurisdiction that imposes an income tax substantially similar to NZ’s. This exemption lifts them out of the 183-day rule that would traditionally trigger tax residency. Key Conditions: • Work must be exclusively for overseas clients or employers. • No on-site services to NZ individuals/businesses. • Work must not require the person to be physically present in NZ. • Must not undertake promotional work in NZ for NZ businesses. Interestingly, the carve-out for work that requires a person to be physically present in NZ uses an example of an influencer. The influencer is required to be physically present in NZ for her work, for example, a travel blogger. Such a person would not qualify for the exemption. Income Exemptions Clarified Under the proposed rules, certain categories of income are explicitly exempt for non-resident visitors: • Personal or professional services income earned while in NZ, provided it meets the non-resident visitor criteria. • Business income earned by a non-resident business or self-employed person that might otherwise be sourced in NZ due to a visitor’s presence is also exempt, unless it arises from a permanent establishment. • Income earned by a public entertainer is not covered by the proposed tax exemptions. Importantly, the activities of a non-resident visitor will be disregarded when determining whether a foreign entity has a permanent establishment in NZ. These proposals should ensure that remote work for foreign clients doesn’t inadvertently trigger NZ tax or permanent establishment issues. GST Registration Becomes Optional The Bill also proposes making GST registration optional for remote workers providing zero-rated services to overseas clients, even if their (zero-rated) turnover exceeds NZD 60,000. Looking Ahead If enacted from 1 April 2026, these proposals represent a significant shift in how New Zealand taxes visiting individuals and their non-resident employers. By aligning the tax rules with the conditions of visitor visas, the reforms introduce a welcome simplification and surprising tax relief.

Among the biggest winners from the Government’s proposed Foreign Investment Fund (FIF) reforms are likely to be US citizens living in New Zealand. The proposed Revenue Account Method, which is set to take effect from 1 April 2025, offers significant relief from the sometimes harsh and often unfair outcomes created when the US and NZ tax systems collide. The Double Tax Problem for US Citizens Unlike most countries, the United States taxes individuals based on citizenship, not residency. This means that US citizens remain fully taxable by the IRS no matter where in the world they live. When they become New Zealand tax residents, they are subject to NZ’s FIF rules – which tax unrealised gains each year. The problem is that these deemed gains are not recognised by the US tax system, which only taxes actual income or realised gains. This mismatch creates a common scenario where a US citizen in NZ pays tax to New Zealand on phantom FIF income (including unrealised capital gains) but then pays US tax again when the investment is eventually sold – with no US tax credit for the NZ tax already paid. The result is real, permanent double taxation. How the Revenue Account Method Helps The proposed Revenue Account Method addresses these challenges by bringing New Zealand’s tax treatment of FIF investments more in line with the US tax system, as it only taxes: Tax is only triggered when dividends are received or capital gains are realised, allowing US citizens to align taxable events across both jurisdictions. Capital gains are only partially taxed in NZ (70%), and foreign tax credits may be available in the US when realisation occurs (US tax advice will be required). For example, under current rules, FIF income is often calculated using the Fair Dividend Rate (FDR) method – which taxes 5% of the opening value of most foreign shares annually, even if no income is actually received. While this is straightforward from a compliance perspective, it does not align well with US capital gains tax rules, which only tax gains when they are realised. This mismatch can lead to several problems: Double taxation : US citizens in New Zealand can be taxed on notional income under the FIF regime that doesn’t correspond to any US tax liability, meaning no foreign tax credit is available in the US. Compliance complexity : The requirement to use different tax bases (realisation for US purposes, deemed accrual/unrealised gains in NZ) creates extra complexity for reporting and record-keeping. Cash flow issues : As no cash is received under FDR (and potentially CV), taxpayers may be forced to fund NZ tax from other sources or liquidate investments earlier than intended. For US citizens holding private equity, start-up shares, or unlisted interests acquired prior to NZ tax residency, this new method could make a substantial difference. It removes the need to fund NZ tax liabilities out of pocket for income never actually received. The new Revenue Account Method should be especially attractive to US citizens holding equity in start-ups, employee share schemes, or private investment vehicles, where growth potential is high but cash flow is minimal. However, it is important to remember that ultimately this method will still tax capital gains on these offshore investments, as well as taxing dividends. The Revenue Account Method should not be a default go-to for new residents, as some taxpayers may have more favourable outcomes with the existing FIF methods. See our more detailed article on the new Revenue Account Method here. Planning Tips for US Citizens and Advisors If you or your clients are US citizens becoming NZ tax residents, consider the following planning steps: Document asset values on entry : For investments eligible for the Revenue Account Method, the cost base will be the value at the time NZ tax residence begins. A formal valuation may be required to substantiate this. Review eligibility : Confirm that the taxpayer became fully tax resident in NZ on or after 1 April 2024 and that investments were acquired before residency (or pursuant to pre-residency arrangements). Coordinate with US tax advisors : Cross-border alignment is key. A coordinated strategy that considers both US and NZ tax consequences will reduce surprises and improve outcomes.
