RAM Expanded: A More Practical Approach to Taxing Foreign Shares
This is a subtitle for your new post
New Zealand’s foreign investment fund (FIF) rules have long caused problems for migrants holding overseas shares, particularly US citizens and Green Card holders living in New Zealand.
The United States generally continues to tax these individuals on their worldwide income even when they are tax resident in New Zealand. At the same time, New Zealand’s FIF rules can impose tax on deemed income that does not match the income or gains recognised in the United States.
This mismatch can create cash flow problems and, in some cases, double taxation because the tax paid in one country may not be available as a credit in the other.
A new revenue account method (RAM) was introduced to address these concerns. However, the original rules were narrowly targeted. Following lobbying from tax advisers, migrants, investors and others affected by the rules, the Government announced a significant expansion as part of Budget 2026.
These changes have already been widely discussed. In this article, we explain what they mean, particularly for US citizens living in New Zealand, and provide an update on where they have reached in the legislative process.
Why are the FIF rules difficult?
The FIF rules generally apply when a New Zealand tax resident holds shares in a foreign company.
The most commonly used calculation method is the fair dividend rate (FDR) method. Broadly, FDR taxes 5% of the opening market value of a foreign share portfolio, together with an adjustment for certain shares bought and sold during the year.
This can produce taxable income even where:
- no shares have been sold;
- no dividends have been received;
- the investment has produced no cash; or
- the investment has ultimately fallen in value or failed.
This can be particularly harsh for people holding shares in an overseas private company or start-up. Tax may be payable each year on deemed income, even though the company has not paid a dividend and the shares cannot readily be sold to fund the tax.
It is also problematic for US citizens. New Zealand may impose tax each year under FDR, while the United States may not tax the gain until the shares are sold. Because the two countries are taxing different amounts at different times, effective foreign tax credits may not be available.
RAM: a “pay when you sell” method
The new RAM taxes qualifying foreign shares on a realisation basis.
Instead of being taxed each year on deemed income, an eligible taxpayer is generally taxed on:
- dividends received; and
- 70% of the gain realised when the shares are sold.
A corresponding 70% of a realised loss may be recognised, although the use of RAM losses is restricted. For example, if an eligible taxpayer receives a $1,000 dividend and realises a $100,000 gain, their taxable RAM income would generally be:
- $1,000 dividend + 70% of the $100,000 gain = $71,000.
- RAM does not impose tax at a flat rate of 70%. Rather, 70% of the gain is included in the person’s taxable income and taxed at their applicable marginal tax rate.
This approach is much closer to the capital gains regimes familiar to migrants from countries such as the US. It also means the taxpayer generally has cash from the sale available to fund the resulting tax.
RAM was introduced but the initial rules were narrow
The original RAM legislation applies from 1 April 2025.
However, it is broadly limited to recent migrants and returning New Zealanders who:
- became fully subject to New Zealand tax on or after 1 April 2024; and
- had been non-resident for at least five years before becoming resident.
Ordinary RAM generally applies only to qualifying unlisted foreign shares acquired before the person became a New Zealand tax resident.
An extended version of RAM can cover listed and unlisted shares held by people who remain liable to tax in another treaty country because of their citizenship or right to live and work there. This is principally aimed at US citizens and Green Card holders.
However, under the enacted rules, these individuals must still satisfy the recent-migrant requirements. This excludes US citizens who have already lived in New Zealand for several years, even though they face the same double-tax problem.
Budget 2026 proposes a major expansion
Following lobbying by the tax industry and people directly affected by the rules, the Government announced a broader RAM regime in Budget 2026.
The changes would:
- allow all New Zealand residents to use RAM for qualifying unlisted foreign shares;
- allow qualifying US citizens and others subject to citizenship-based taxation to use extended RAM for listed and unlisted foreign shares, regardless of when they migrated to New Zealand; and
- increase the FIF de minimis threshold from $50,000 to $100,000.
The removal of the recent-migrant restriction from extended RAM will be particularly helpful for US citizens and Green Card holders who have lived in New Zealand for many years.
Once enacted, these taxpayers should be able to align their New Zealand tax more closely with the time at which the United States recognises the gain. This should reduce cash flow problems and the risk of tax being paid in both countries without an effective foreign tax credit.
The expansion of ordinary RAM will also help New Zealand residents holding shares in overseas private companies. Instead of potentially paying tax each year on an investment that produces no cash, tax would generally arise when a dividend is received or the shares are sold.
The de minimis threshold is also increasing
Individuals generally do not have to apply the FIF rules where the total cost of their relevant foreign investments does not exceed $50,000.
The Government proposes increasing this threshold to $100,000 from 1 April 2026. This should remove many smaller investors from the FIF regime, significantly reducing their compliance costs.
The Budget changes are not yet law
The expanded RAM rules and the $100,000 de minimis threshold were not included in the Budget night legislation and have not yet been enacted. We expect these changes to be included in the 2026–27 Annual Rates Bill later in 2026. If enacted as proposed, they should apply from 1 April 2026.
The detailed legislation will be important. In particular, it should confirm the final eligibility requirements and whether the expanded RAM will be available to companies as well as individuals and qualifying trusts.
Until then, taxpayers should distinguish between:
- the original, narrowly targeted RAM rules, which are already law; and
- the broader Budget 2026 changes, which remain proposals.
Is RAM necessarily the best method?
RAM will not always produce the lowest amount of New Zealand tax.
FDR may be more favourable where an investment increases significantly in value because annual FIF income is generally based on 5% of opening value. Under RAM, 70% of a realised gain becomes taxable when the investment is sold.
The method chosen can also have longer-term consequences. It may not be possible to move freely between RAM and the existing FIF methods, and leaving RAM may trigger a deemed disposal.
The choice should therefore be made after considering:
- the nature and expected performance of the investments;
- whether the shares are listed or unlisted;
- when they were acquired;
- the taxpayer’s New Zealand residency history;
- the taxpayer’s US tax obligations;
- the availability and timing of foreign tax credits; and
- the treatment of losses.
A welcome and practical change
The proposed expansion of RAM is a welcome response to concerns raised by the tax industry and the people directly affected by the FIF rules.
It should reduce the risk of taxpayers having to fund tax on income they have not received, provide much-needed relief for long-term US citizens living in New Zealand and make New Zealand a more attractive place for migrants and returning New Zealanders to live and invest.
However, the rules are complex, and the choice of method matters. US citizens and other affected investors should review their portfolios before preparing their FY26 tax returns and obtain coordinated New Zealand and overseas tax advice. Contact us if you need assistance.
