Exit Tax UK Pension Rules: What Renouncing Americans File

A UK pension can do two jobs in a renunciation: push you over the net worth line, then be taxed in one lump as ineligible deferred compensation. Here is how it is valued, what the exclusion does not shelter and a worked example.

Exit tax UK pension: an introduction

The exit tax UK pension rules matter only if you are a covered expatriate, but they bite hard if you are. A UK pension counts towards the $2 million net worth test. If you are then covered, the pension is usually an ineligible deferred compensation item. That means its present value is treated as received on the day before you expatriate, and taxed as income. The exit tax exclusion amount does not shelter it. So the pension can matter twice.

This article supports our guide to IRS Streamlined Filing from the UK, because compliance comes first. Our expatriation service covers the filings around renunciation. For the overall charge, see our article on the US exit tax.

Why the exit tax UK pension question is different

Most assets go through a deemed sale, with gain above an exclusion amount being taxed. Pensions take a separate route in section 877A(d). It applies to interests in a foreign pension plan or similar arrangement. Therefore, you cannot read general exit tax guidance and assume your pension simply adds to your gains.

How does a UK pension count in the covered expatriate tests?

It counts in the net worth test as part of your assets. You need to work through all three on Form 8854.

The three tests

The Form 8854 instructions give the tests. For 2025, you are covered if your average annual net income tax for the prior five years exceeds $206,000. You are also covered if your net worth is $2 million or more on the expatriation date. Finally, you are covered if you do not certify five years of compliance. The first figure is indexed each year, while the $2 million figure is not.

Why pensions often tip the balance

A person with a London home and a good workplace pension can reach $2 million without feeling wealthy. A strong pound makes that easier, since the test is measured in dollars. Valuing a defined benefit pension also surprises people, because a modest annual income can imply a large capital value. Notice 2009-85 refers back to Notice 97-19 for the status tests. Pension-specific net worth valuation is less clear, so we record the method used.

The dual citizen exception

Some people who were dual citizens from birth, or who are certain minors, can avoid the first two tests if they meet the conditions. They must still certify compliance. So a British-American who qualifies might have a large pension and no pension charge. Our article on dual citizens renouncing explains that exception. Check it before any other work.

Is a UK pension eligible or ineligible deferred compensation?

Almost always ineligible. An eligible item requires a US payor, or one that elects to be treated as one, plus a notification and treaty waiver from you. A UK pension provider is very unlikely to do this.

What eligible treatment would mean

For eligible items, the payor withholds 30% of each taxable payment, and there is no lump-sum charge. You notify the payor on Form W-8CE and give an irrevocable treaty waiver on Form 8854. A US 401(k) can fit this model, which is why US and UK plans can come out so differently on one person's Form 8854. Our pensions service deals with both.

What ineligible treatment means

Section 877A(d)(2) treats you as receiving the present value of your accrued benefit on the day before expatriation. It is included in your final return for the part of the year that includes your expatriation date. Fortunately, no early distribution tax applies because of this treatment. Nevertheless, it is ordinary income in a single year, regardless of when the pension will actually pay.

Not a specified tax deferred account

Section 877A(e) deals with specified tax deferred accounts, such as individual retirement plans. They are treated as fully distributed on the day before expatriation. The statute's list starts with US-style accounts, and foreign pensions appear instead in the deferred compensation definition. Therefore, a UK SIPP is generally analysed as a foreign pension plan or similar arrangement. A Roth or traditional IRA goes the other way, even if held by a UK resident.

The annual statement from a UK pension scheme is the starting point for the value that goes on Form 8854.

How is the present value worked out?

It depends on the type of plan. A defined contribution value is straightforward, whereas a final salary or career average pension needs an actuarial calculation.

Defined contribution pensions and SIPPs

Notice 2009-85 says that for a defined contribution plan, the present value of the accrued benefit is the account balance. So you take the balance on the day before expatriation, converted to dollars. Get a written valuation for that date rather than relying on your last annual statement.

Defined benefit pensions

For a defined benefit plan, the notice uses the method in section 4.02 of Rev. Proc. 2004-37. A UK scheme will not normally produce that figure for you. Therefore, expect to obtain the scheme's benefit details and use an actuary. The scheme's own cash equivalent transfer value is a UK measure, and it may differ. We use it as a reasonableness check, not as the answer.

The UK tax-free lump sum

The UK's tax-free pension lump sum is a UK relief, and the exit tax rules do not carve it out. The whole present value generally enters the US calculation. In addition, any investment in the contract matters. Treaty relief on contributions means many Americans in UK plans have little basis, so the figure needs real evidence. Practice on foreign pension basis varies, and we take the cautious approach.

What does a worked example show?

The result can turn on one test. Consider a typical case with invented figures and an assumed rate of $1.30 to the pound.

The facts

Oliver is a US citizen, born in Ohio, who has lived in Bristol for decades. He is not a dual citizen from birth, and his five years of filings are complete. He holds £750,000 of home equity, a £600,000 SIPP and £200,000 of savings. His average US tax is low, because UK tax is credited. He plans to renounce in 2026.

The test

His net worth is £1,550,000, or $2,015,000 at the assumed rate. That passes the $2 million line by a slim margin. If the SIPP were not counted, he would be well below it. So his pension alone makes him covered, and exchange rates could change the answer.

The charge

The SIPP is ineligible, so $780,000 is treated as received the day before expatriation. Suppose his effective US rate on that income is about 35%, which is an assumption. The charge is then about $273,000. His $780,000 is ordinary income, and the mark-to-market exclusion of $890,000 for 2025, which is indexed, applies to net gain on his other property, not to this. Furthermore, the UK has charged no tax that year, so he may have little foreign tax credit to use.

What happens to later UK tax

In later years, he draws the pension in the UK and pays UK income tax. Section 877A(d)(2)(C) requires adjustments to later distributions, to reflect the tax already imposed. As a non-US person, though, he will generally have no further US return on it. Consequently, his later UK tax does not obviously reach back to credit the earlier US tax. A one-year carryback rule offers little here. Therefore, the sequence is a true cost that needs modelling.

What should you do before renouncing?

Work in this order, because each step feeds the next. The US State Department handles the oath, but the tax outcome is set by what is true on the expatriation date.

Step one: confirm compliance

You must certify five years of compliance on Form 8854, or you are covered regardless of your wealth. Missed UK pension reporting is a common problem. Our article on the UK pension on the FBAR covers one part of it. The IRS Streamlined Filing Compliance Procedures may help non-wilful taxpayers catch up first.

Step two: build a dollar balance sheet

List every asset, including the pension at a defensible value, and every debt. Convert it all at the expatriation-date rate you expect, then test sensitivity. An exit near the $2 million line deserves particular care.

Step three: model the outcome

We model what your Form 8854 and final return show with the pension counted, at several exchange rates. Decisions about your assets are yours and your financial adviser's. What we provide is a clear figure for what would be filed. Our expatriation service prepares these forms.

Step four: gather the evidence

Request a dated valuation from each scheme, your contribution history and any employer records of basis. Keep them for the file. A deemed distribution figure that cannot be supported is a poor position with the IRS.

Does the US-UK treaty remove the charge?

Do not assume so. The US-UK treaty has articles on pensions and a saving clause that keeps much US taxing power over citizens, and in some cases former citizens. Whether a treaty position can reduce an exit tax UK pension charge is contested.

The cautious approach

Section 877A was enacted after the treaty, and it is written as a deemed receipt rather than a real pension payment. Some advisers argue that the pension article should still apply. We treat any such claim as a position to examine with specialist legal input, disclose on Form 8833 if taken, and never as the default. Therefore, the model you use for your decision should assume no treaty relief.

The US contributions question

The treaty relief you may have used on pension contributions is a separate matter. It changes your past US income, and so your investment in the contract, rather than this year's charge. Consequently, past returns need reading alongside the current calculation. A careful exit tax UK pension file includes both.

What stays the same in the UK?

Almost everything. HMRC does not change its treatment of your pension because you gave up a US passport.

UK income tax on drawdown

UK tax on pension income continues under normal rules, and your annual allowance and contribution rules also continue. Renouncing brings no UK relief. Moreover, it does not change your UK residence, which turns on separate tests. Our UK tax services page covers the wider position.

Filing dates to keep in mind

You file your final US return for the year of expatriation with Form 8854, and the deemed amount goes on that return. The IRS expatriation tax page summarises the regime, and the US State Department handles the legal act of renouncing. These run separately, so the citizenship date can arrive some time before the tax return. Reserve cash for the charge from the moment you book the appointment. Our article on how to renounce US citizenship sets out the process.

A second person in the household

A US spouse who stays American, or who renounces later, has a separate test and a separate pension. The exit tax UK pension position is personal to each of you. Assets moved between spouses before an expatriation date need separate review, and transfers to a non-citizen spouse have their own rules. We prepare each person's Form 8854 from the same schedule, so the two sets of figures are consistent.

When the exit tax UK pension charge does not arise

Many people who renounce from Britain are not covered, and then no deemed distribution applies. Their pension simply stays in the UK system. An exit tax UK pension review may therefore end with a short, reassuring answer. You still need the tests worked through and recorded on Form 8854, even when the result is no charge.

How US UK Tax Experts can help

US UK Tax Experts prepares and files your final US return, Form 8854 and your UK returns from one file, so the two agree. For an exit tax UK pension question, we work out the tests, gather scheme values and prepare the reporting of the deemed amount. We do not give investment, financial or pension advice. We work with your own advisers, and we do not promise an outcome.

Conclusion

The pension can make you covered and then be taxed at once as income. For an exit tax UK pension position, confirm first whether you can avoid being covered at all, through compliance or the dual citizen exception. Next, value each scheme for the date itself and model the charge. Finally, remember that the exclusion amount does not help, and that later UK tax may not offset it.

Frequently asked questions

Yes, your pension is an asset for that test. A SIPP or a workplace pension can push a homeowner over the line, and the test is measured in dollars. Exchange rates on the expatriation date can therefore matter.

It is usually an ineligible deferred compensation item under section 877A(d). Its present value is treated as received on the day before you expatriate, and it is included as income on your final return. No early distribution tax applies to that deemed amount.

No, the exclusion amount applies to net gain on the deemed sale of your other property. An exit tax UK pension amount is separate deferred compensation income. The exclusion was $890,000 for 2025 and is indexed each year.

Generally no, because eligible treatment needs a US payor or one that elects to be treated as US. A UK provider is unlikely to do that. Form W-8CE mainly works for US plans such as a 401(k), and its notification has its own timing rule.

Notice 2009-85 uses the method in section 4.02 of Rev. Proc. 2004-37 for defined benefit plans. A UK scheme will not usually provide this, so an actuary is often needed. A transfer value is useful as a check, but it may differ.

Probably yes, because the UK taxes the pension when you draw it. An exit tax UK pension charge happens years earlier, so later UK tax may not reduce it. That timing gap is a real cost to model before you decide.
