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:
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:
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.
