A UK reporting fund is an offshore fund that HMRC has approved for reporting status and that reports its income to investors every year. It matters because, once you are UK tax resident again (2026/27 rules), gains on reporting funds are generally taxed as capital gains, while gains on non-reporting funds are generally taxed as income. For a higher rate taxpayer that can mean 24% rather than 40% or 45%, subject to your other income and any reliefs.

What counts as an offshore fund

Many funds set up outside the UK can be offshore funds for UK tax. That includes many funds domiciled in Ireland, Luxembourg, the Channel Islands and the US, as well as funds held inside international investment platforms. Expats often build portfolios of these funds while abroad, sometimes without knowing whether they have UK reporting status, because it makes little difference while living in a country such as the UAE.

How the two types are taxed for UK residents

HMRC's guidance sets out the difference:

  • Reporting funds. You pay income tax on distributions you receive plus your share of any income the fund retains, known as excess reportable income. On disposal, the gain is generally taxed under capital gains tax, provided the fund had reporting status throughout your holding.
  • Non-reporting funds. You pay income tax on distributions. On disposal, the whole gain is generally treated as an "offshore income gain" and taxed as income, at your marginal income tax rate.

For 2026/27, capital gains tax is 18% or 24% with a GBP 3,000 annual exempt amount. Income tax in England, Wales and Northern Ireland runs at 20%, 40% and 45% (Scotland has different bands), and the capital gains annual exempt amount does not apply to offshore income gains. The aim of the rules is to stop income being rolled up offshore and then taken as capital.

If a fund gained or lost reporting status part way through your holding, the calculation becomes more complex.

Why it matters on your return

While you are non-resident, the UK generally does not tax gains on these funds, subject to the temporary non-residence rules. The question becomes live when you become UK resident again. Points to bear in mind:

  • Gains already built up. Generally, when a UK resident disposes of a non-reporting fund, the whole gain since purchase can be an offshore income gain, including growth that built up while abroad. Some people review their holdings before returning for this reason.
  • Temporary non-residence. If you left after being UK resident in at least four of the seven tax years before departure and return within five years, offshore income gains made while abroad can be taxed in the year you return.
  • Long absences. If you have been non-resident for at least 10 consecutive tax years, you may be able to claim the four-year foreign income and gains regime in your first years back, depending on the type of income or gain. Check carefully whether it covers your holdings before relying on it.
  • Ongoing reporting. Reporting funds require you to include excess reportable income on your tax return each year, even if you received no cash.

How to check a fund

HMRC publishes a list of approved reporting funds, updated monthly. Match each holding against the list, using its fund name and identifier. Fund managers often confirm reporting status in their factsheets or annual reports too.

Illustrative example only, not a real client. Tom has a GBP 100,000 gain on an offshore fund he bought in Dubai. He sells it a year after returning to England, in a tax year when his only other income is a GBP 60,000 salary. Assumptions: 2026/27 rates for England, Wales and Northern Ireland, no other gains, no losses, no temporary non-residence charge and no foreign income and gains relief. If the fund had reporting status throughout, the gain after the GBP 3,000 exempt amount (GBP 97,000) would be taxed at 24% because his salary already uses the basic rate band: GBP 23,280. If it was non-reporting, the GBP 100,000 would be added to his income. His total income tax would rise from GBP 11,432 to GBP 58,203, an extra GBP 46,771, partly because his personal allowance would be withdrawn above GBP 100,000 of income.

Common mistakes

  • Assuming a well-known fund must have UK reporting status.
  • Selling a non-reporting fund just after becoming UK resident rather than reviewing beforehand.
  • Forgetting to declare excess reportable income on the tax return.
  • Overlooking the five-year temporary non-residence rule.
