Missed UK Tax Returns: US REIT Dividends for UK Residents

A US-listed REIT dividend that the IRS divides into four differently taxed parts is, for a UK resident, generally a single foreign dividend taxable in full. Missed UK tax returns usually arise here because the Form 1099-DIV was treated as the whole answer and the UK position was never computed, or was computed in the wrong category.

This guide is written for UK-resident Americans who hold shares in US-listed real estate investment trusts through a US brokerage account. Despite the name, these are listed property companies taxed as corporations, and this guide deals only with them as ordinary portfolio shareholdings. It sets out how the US return treats each box of Form 1099-DIV, how the same cash is characterised for UK purposes, which country gives credit for the other's tax under the treaty, how to convert to sterling, and how earlier UK returns that omitted or misclassified the income are put right. It is a different subject from UK REITs and their property income distributions, which follow their own statutory regime and which we cover separately in our guides library.

Why do US REIT dividends cause missed or wrong UK tax returns?

At Jungle Tax we see the same four patterns repeatedly when preparing catch-up returns for clients with substantial US portfolios:

• The income was never reported in the UK at all. The US brokerage account pre-dates the move to the UK, the dividends are reinvested automatically, no sterling ever arrives in a UK bank account, and the client assumed the US return dealt with it.
• Only box 1a was reported. The preparer picked up ordinary dividends but left out capital gain distributions and nondividend distributions because they are not ordinary income on the US return.
• The income was reported in the wrong UK category. US REIT distributions were entered as overseas property income, or the capital gain distributions were entered on the capital gains pages. Both produce the wrong rate of tax.
• The calendar year was used. The 1099-DIV totals for January to December were dropped into a UK return that runs from 6 April to 5 April.

None of these is unusual, and all are correctable. The first step is to understand why the two systems see the same payment so differently.

How does the US tax a REIT distribution on Form 1099-DIV?

A US REIT generally pays no corporate tax on income it distributes, so US law looks through to the character of what was distributed. The broker reports the result on Form 1099-DIV, and a single quarterly payment is commonly split across several boxes once the REIT publishes its year-end tax allocation.

Box 1a and box 5: ordinary dividends and section 199A dividends

Most REIT income falls in box 1a as ordinary dividends. Very little of it normally appears in box 1b as qualified dividends, because the REIT itself has not paid corporate tax on the underlying rents. Ordinary REIT dividends are therefore taxed at the shareholder's ordinary federal rates rather than the preferential 15% or 20% rates.

The compensation is box 5. Section 199A dividends qualify for a deduction of up to 20% of the amount, claimed on Form 8995 or Form 8995-A, provided the shares were held for more than 45 days in the 91-day period beginning 45 days before the ex-dividend date. For a taxpayer in the top 37% bracket, the deduction brings the effective federal rate on those dividends to 29.6% before the net investment income tax. The deduction was originally due to expire after 2025 and has since been made permanent.

Box 2a and box 2b: capital gain distributions and unrecaptured section 1250 gain

When a REIT sells property at a gain and distributes the proceeds, it can designate part of its dividend as a capital gain distribution. That amount appears in box 2a and is long-term capital gain in the shareholder's hands regardless of how long the shares have been held. Box 2b is a subset of box 2a: the portion attributable to depreciation previously claimed on real property, known as unrecaptured section 1250 gain, which is taxed at a maximum federal rate of 25% rather than 20%.

Box 3: nondividend distributions

Because depreciation reduces a REIT's earnings and profits without reducing its cash, REITs frequently distribute more cash than their tax earnings. The excess is reported in box 3 as a nondividend distribution, often called a return of capital. It is not taxed in the year of receipt. Instead it reduces the shareholder's basis in the shares, and once basis reaches zero any further amount is taxed as capital gain. The practical effect is deferral: the tax is collected when the shares are sold.

The net investment income tax

Above the statutory income thresholds, the 3.8% net investment income tax applies to dividends and capital gains, including REIT income. It sits outside the regular income tax, and the IRS position is that foreign tax credits cannot be used against it. Some taxpayers have litigated treaty-based claims to the contrary, with mixed results, so this is a point for the return preparer to address deliberately rather than by default.

How does the UK tax the same distribution?

The UK starts from a different question. It does not ask what the company's underlying income was. It asks what the shareholder received and from what kind of entity.

A dividend from a non-UK company, not property income

A US REIT is a corporation. A distribution on its shares is, for a UK-resident individual, generally a dividend from a non-UK resident company, charged to income tax as foreign dividend income. The UK legislation that converts REIT distributions into profits of a property business, the property income distribution regime, applies only to companies within the UK REIT rules. There is no equivalent deeming provision for an overseas REIT.

This matters because the rates differ materially. For 2026-27 dividend income is taxed at 10.75%, 35.75% and 39.35% after a £500 dividend allowance, whereas property income is taxed at the main rates of 20%, 40% and 45%. For 2025-26 and the two preceding years the dividend rates were 8.75%, 33.75% and 39.35%. Readers should be aware that informal guidance, including replies on HMRC's own community forum, has at times suggested that distributions from non-UK REITs belong on the overseas property pages. We regard the statutory analysis above as the better view for a US corporate REIT, but where earlier returns were filed on the other basis the point should be reviewed rather than assumed.

Capital gain distributions are still dividends in the UK

The fact that a dividend was funded from the company's capital gains does not make it a capital receipt of the shareholder. A box 2a capital gain distribution, including the box 2b unrecaptured section 1250 element, is normally taxed in the UK as dividend income at the rates above. It does not belong on the capital gains pages, it does not benefit from the annual exempt amount, and it is not taxed at the 18% or 24% capital gains rates. For an additional rate taxpayer that is 39.35% of UK tax on income the US taxes at 20% or 25%.

Return of capital: usually income in the UK

This is the point most often missed. The foreign dividend charge excludes dividends of a capital nature, and HMRC's guidance at SAIM5210 explains that the test is whether the shareholder's underlying asset is left intact after the payment, determined by reference to the mechanism used under the company law of the territory concerned. A box 3 amount is not a return of share capital in that corporate-law sense. It is an ordinary cash dividend that exceeds earnings and profits as measured by US tax rules, largely because of depreciation. The shares are untouched.

The general result is that a box 3 nondividend distribution is taxable dividend income in the UK in the year it is paid, even though the US taxes nothing that year. Only where a payment is genuinely capital under the relevant corporate law, such as a distribution in a liquidation or a formal reduction of capital, would it fall instead into the capital gains rules as a capital distribution treated as a part disposal of the shares.

The base cost divergence nobody tracks

A consequence follows on sale. The US basis in the shares has been reduced by every box 3 distribution, while the UK base cost has not, because the UK already taxed those amounts as income. On disposal the US gain is larger than the UK gain, quite apart from exchange rate differences. The sterling base cost is also fixed using the exchange rate at acquisition and the proceeds at the rate on disposal, so a dollar loss can be a sterling gain and vice versa. Records kept only in dollars, and only on the US basis, will produce the wrong UK capital gains figure years later.

Which country gives the credit under the US-UK treaty?

A UK-resident American is taxed on the same dividend by both countries: by the UK on the basis of residence and by the US on the basis of citizenship. The treaty's saving clause preserves the US right to tax its citizens as if the treaty did not exist, so the relief has to come from the special rules for citizens in Article 24. The treaty and its technical explanation are published on the gov.uk USA tax treaties page.

Step one: the UK credits US tax only up to the treaty rate

The UK is required to credit only the US tax that the treaty would permit the US to charge a UK resident who is not a US citizen. For a portfolio investor in a publicly traded REIT, Article 10 generally caps that at 15% of the gross dividend, provided the conditions for REIT dividends are met; broadly, for a listed REIT, a holding of no more than 5% of the relevant class of shares. The UK foreign tax credit is therefore normally 15% of the gross dividend or the UK tax on that dividend if lower, whatever the actual US tax paid by the citizen.

Two practical points follow. First, a US citizen holding through a US broker typically has no tax withheld at source at all, so the 15% is a computed figure taken from the US return, not a figure on the brokerage statement. Second, for a basic rate UK taxpayer the dividend rate is below 15%, so the credit is capped at the UK tax and no UK tax is payable on that slice.

Step two: the US credits the remaining UK tax

The US then allows a foreign tax credit for the UK tax actually paid, net of the credit the UK gave. To make that work, the treaty treats the dividend as foreign source to the extent necessary, and the credit is computed on Form 1116 in the separate category for income re-sourced by treaty. The US is not required to reduce its tax below the 15% it could have charged a non-citizen.

A worked illustration

Assume an additional rate UK taxpayer in the top US bracket receives a section 199A dividend equivalent to £10,000 in 2026-27, with the dividend allowance already used.

• UK tax at 39.35%: £3,935.
• UK credit for US tax at the 15% treaty rate: £1,500. UK tax payable: £2,435.
• US regular tax after the 20% deduction, at 37% on £8,000: £2,960.
• US tax above the 15% floor: £1,460. This is sheltered by the £2,435 of net UK tax, subject to the Form 1116 limitation.
• Residual US regular tax: broadly the £1,500 the UK has already credited, plus any net investment income tax.

The combined burden is close to the higher of the two countries' rates rather than the sum, but only if both returns are prepared together. Where the UK return was never filed, the US return will usually have paid full US tax with no credit, and the missed UK filing then triggers an amended US return to claim it. Our US-UK tax accountants prepare both sides as one computation for exactly this reason.

Where the mismatches bite

• Capital gain distributions. UK tax at up to 39.35% exceeds US tax at 20% or 25%, generating surplus UK tax that can only be used within the same Form 1116 category, subject to the carryback and carryforward rules.
• Return of capital. The UK taxes it in the year of payment; the US taxes it, in effect, on sale. There is no US tax in the year to credit, and no US income in the re-sourced category against which the UK tax can be absorbed that year. Timing mismatches of this kind are a principal reason foreign tax credits expire unused.

Sterling conversion and the tax year mismatch

The UK return is prepared in sterling for the year to 5 April. Each dividend is taxable when it is paid and should be translated at the rate for that date. HMRC publishes monthly and yearly average exchange rates, and a reasonable method applied consistently is generally accepted. The US return, by contrast, translates UK tax paid into dollars for a calendar year.

The reliable approach is a dividend-by-dividend schedule built from the brokerage statements, with the payment date, the dollar amount, the sterling equivalent and, once the REIT has published its final allocation, the split between ordinary, capital gain and nondividend components. January to early April dividends belong to the earlier UK tax year even though they appear on the later 1099-DIV. Year-end reallocations by the REIT, sometimes issued on a corrected 1099-DIV, change the US figures but generally not the UK total, because the UK taxes the whole payment as a dividend in any event.

How do you correct UK returns that omitted or misclassified US REIT income?

The route depends on whether a return was filed, how long ago, and whether tax was underpaid or overpaid.

Returns that were filed but are wrong

• Within the amendment window. A Self Assessment return can be amended within twelve months of the 31 January filing deadline. The 2024-25 return, due 31 January 2026, can generally be amended until 31 January 2027.
• Outside the window, tax underpaid. The correction is made by disclosure. Because the income arises outside the UK, HMRC expects the Worldwide Disclosure Facility to be used: the taxpayer notifies, and then has 90 days to submit the computation, the behaviour assessment and payment.
• Outside the window, tax overpaid. Where dividends were reported as property income at 40% or 45%, the correction may produce a repayment. Overpayment relief must be claimed within four years of the end of the tax year concerned.

Misclassification does not always run in the taxpayer's favour. Capital gain distributions reported as capital gains will have been undertaxed, and unreported box 3 amounts are additional income. A single revised computation should net these effects year by year.

Returns that were never filed

A UK resident with untaxed foreign income must notify HMRC of chargeability by 5 October following the end of the tax year. Where that did not happen, the catch-up involves registering for Self Assessment and either filing the outstanding returns or including the years in a disclosure. Where returns were issued and not filed, the fixed and tax-geared late filing penalties run separately: an initial £100, daily penalties after three months, and further penalties at six and twelve months.

How far back, and what penalties?

HMRC's ordinary assessment window is four years from the end of the tax year, six years where the loss of tax was careless and twenty where it was deliberate. For offshore income, which includes dividends from US companies, a twelve-year window can apply even without deliberate behaviour. Liabilities for 2015-16 and earlier that were not corrected by 30 September 2018 may also fall within the separate failure to correct regime, which carries substantially higher penalties.

For later years, penalties are a percentage of the tax understated, set by behaviour and by whether the disclosure was unprompted. The United States is a Category 1 territory, so the standard ranges apply without the offshore uplift: up to 30% for careless inaccuracies, reducible to nil for a full unprompted disclosure, and higher bands for deliberate behaviour. A reasonable-care argument is often available where a qualified adviser was engaged and given full information. Interest runs on all late-paid tax regardless.

New arrivals: the four-year regime needs a claim

From 6 April 2025 the remittance basis was replaced by the foreign income and gains regime. An individual in the first four tax years of UK residence after at least ten consecutive years of non-residence can claim relief so that foreign income, including US REIT dividends, is not charged to UK tax. The relief is not automatic. It must be quantified and claimed on a Self Assessment return by 31 January in the second tax year after the year of claim, and it costs the personal allowance and the capital gains annual exempt amount. A missed return can therefore mean a missed claim, which is a strong reason to bring recent years up to date promptly. For earlier years, the remittance basis may be relevant for those who were not UK domiciled and did not bring the income to the UK.

What about the US side: is anything missed there?

Usually the US returns have been filed, since the broker reports the 1099-DIV to the IRS. The US issues tend to be consequential:

• Unclaimed foreign tax credits. Once UK tax is paid for earlier years, amended US returns can claim credit. A claim for refund based on foreign taxes generally benefits from an extended ten-year period.
• Basis tracking. Box 3 distributions must have reduced US basis year by year; if the broker's cost basis records are incomplete for older lots, the gain on sale will be wrong.
• Information reporting. A brokerage account at a US institution is not a foreign account for FBAR or Form 8938 purposes. UK accounts are. Where those have also been overlooked, the US side may call for the streamlined procedures; see our IRS streamlined filing page.

US REIT shares held directly are also simpler than pooled funds in one respect: as shares in a US operating corporation they are not passive foreign investment companies for US purposes, and a conventional closed-ended listed REIT would not normally be expected to fall within the UK offshore fund rules that affect US mutual funds and exchange-traded funds. That should still be confirmed holding by holding, since funds that merely invest in REITs are a different matter.

A practical catch-up sequence

1. Obtain every Form 1099-DIV, including corrected forms, and the monthly brokerage statements back to the year UK residence began.
2. Build a dividend-by-dividend schedule by payment date and allocate each payment to the correct UK tax year.
3. Convert to sterling on a consistent, documented basis.
4. Recompute UK tax treating the full distribution as foreign dividend income, unless a specific payment is demonstrably capital under the relevant company law.
5. Compute the UK credit at the treaty rate and the residual UK tax.
6. Decide the UK route for each year: amendment, disclosure, late return or overpayment relief claim.
7. Recompute the US foreign tax credit and amend the US returns where a refund or carryover results.
8. Establish sterling base cost records for every lot so that future disposals are reported correctly in both countries.

Our UK tax services and US tax services teams prepare these computations side by side, which is the only way to be confident that the credit claimed in one country matches the tax actually paid in the other.

Key takeaways

• The 1099-DIV split is a US concept. For a UK resident the whole US REIT distribution is generally foreign dividend income.
• Capital gain distributions and return of capital are usually taxable in the UK as dividends, at up to 39.35%.
• The UK credits US tax at the treaty rate, generally 15%; the US credits the rest of the UK tax.
• UK base cost and US basis diverge, and must be tracked separately.
• Errors can run in either direction, so a full recomputation should precede any disclosure.
