US Tax Return Preparation for Expats Leaving a UK LLP

An American member leaving a UK LLP faces two tax systems that describe the same exit in different terms. Sound US tax return preparation for expats splits every exit payment under section 736 into property payments and ordinary income, rebuilds basis in dollars, and then matches UK tax on the final profit share through the foreign tax credit.

That is the short answer. The longer one is that the leaving documents are written by the firm's UK lawyers for UK purposes. They talk about a final profit allocation, repayment of capital, release of the tax reserve and, sometimes, a payment for goodwill or a period of continuing payments. None of those labels is a US tax category. The Internal Revenue Code asks its own questions, on its own calendar, in its own currency. This guide, from the cross-border team at Jungle Tax, sets out how the exit of a US citizen or green card holder from a UK law, accounting, consulting or fund management LLP is reported on both sides, and where the two returns have to be reconciled.

It assumes the LLP is classified as a partnership for US federal tax purposes. If you have not confirmed that, or are unsure whether you have ever had a filing obligation, start with our guide to Form 8865 for UK LLP members.

What actually happens, in tax terms, when you leave a UK LLP?

A typical leaving agreement delivers some or all of the following:

• your share of profit up to the leaving date, often finalised months later when the accounts are signed;
• repayment of your capital account, frequently in instalments and sometimes applied first to repay a partner capital loan;
• the balance on your current account and any tax reserve the firm has held back from drawings;
• in some firms, a fixed sum or a share of future profit for a period after you leave;
• less often, an identified payment for goodwill.

The UK treats the first as trading income, the second and third as your own money coming back, the fourth according to its legal character, and the fifth as a capital disposal. The US starts from a different place. If the LLP itself pays you out, the transaction is a liquidation of your entire partnership interest, and section 736 governs every dollar. If instead the continuing members buy your interest from you directly, it is a sale under section 741 with section 751(a) applying to the ordinary element. The members' agreement, not the covering letter, tells you which it is. Most professional LLP exits are redemptions by the firm, and the rest of this guide follows that pattern.

How does section 736 treat payments to a withdrawing partner?

Section 736 applies only to payments made by the partnership in liquidation of a partner's entire interest. It sorts each payment into one of two classes, and the classification drives the character of the income, the timing, the self-employment tax and the foreign tax credit basket.

Section 736(b): payments for your interest in partnership property

Amounts paid in exchange for your share of the partnership's property are treated as distributions. The ordinary distribution rules then apply: under section 731, money received reduces your outside basis first, and gain is recognised only when money exceeds that basis. Any gain is generally capital. A loss is recognised only where the liquidating distributions consist solely of money, unrealized receivables and inventory, and only once the final payment has been made. Relief from your share of partnership liabilities counts as money received under section 752(b), which matters for an LLP carrying bank debt or a large property lease liability on a US-principles balance sheet.

Section 736(a): everything else

Whatever is not a payment for partnership property falls into section 736(a). If the amount is determined by reference to partnership income, such as a percentage of profit for three years, it is a distributive share. If it is fixed without regard to income, it is a guaranteed payment under section 707(c). Both are ordinary income to you. In broad terms a distributive share reduces what the continuing members are allocated, and a guaranteed payment is deductible by the partnership.

The professional firm rule that changes the answer

For most businesses, unrealized receivables and goodwill are partnership property and payments for them sit in section 736(b). There is a special rule where capital is not a material income-producing factor for the partnership and the withdrawing partner was a general partner. In that case, payments for unrealized receivables, and payments for goodwill unless the partnership agreement expressly provides for a goodwill payment, are removed from section 736(b) and taxed as ordinary income under section 736(a).

Law, accounting and consulting LLPs are the textbook case of capital not being a material income-producing factor. The harder question is whether a member of a UK LLP is a general partner for this purpose. Every member has limited liability under UK law, yet full equity members manage the business and are in substance the partners the rule was written for. There is no settled authority that maps a UK LLP member onto the US distinction, and the position taken should be consistent with how the same member has been treated for self-employment tax. A fund management LLP needs a separate look, because capital may well be material in a vehicle holding co-investment or carried interest. This is a judgement your preparer should document, not assume.

Payment on exit	Usual section 736 class	US character	Self-employment tax
Repayment of capital account	736(b)	Return of basis, then capital gain	No
Share of fixed assets and cash	736(b)	Return of basis, then capital gain	No
Share of unbilled work in progress and uncollected fees (professional firm, general partner)	736(a)	Ordinary income	Generally yes
Goodwill, agreement silent (professional firm, general partner)	736(a)	Ordinary income	Generally yes
Goodwill, agreement expressly provides for it	736(b)	Capital gain above basis	No
Fixed continuing payments for a set period	736(a)(2)	Guaranteed payment, ordinary	Generally yes
Share of future profits for a set period	736(a)(1)	Distributive share, ordinary	Generally yes

What are section 751 hot assets in a professional services LLP?

Section 751 exists to stop ordinary income being turned into capital gain on the way out of a partnership. Its targets are unrealized receivables and inventory. In a professional firm, the receivable that matters is the value of work done and not yet taxed: unbilled time and uncollected fees, to the extent they have not already been included in income under the method the US computation uses.

The mechanics differ by route, but the result is the same:

• In a professional firm where the special rule applies, payments for your share of unrealized receivables are pushed into section 736(a) and taxed as ordinary income directly.
• Where the special rule does not apply, for instance because capital is a material income-producing factor, the receivables remain partnership property, but section 751(b) treats a disproportionate distribution as a deemed sale and produces ordinary income on your share.
• On a sale to the continuing members, section 751(a) carves out the ordinary element before capital gain is measured.

The UK accounts add a wrinkle. UK firms recognise revenue on work in progress under UK GAAP or IFRS, so much of what an American would call an unrealized receivable has already been taxed in the UK as profit. Whether it has been taxed in the US depends on how your distributive share has been computed each year. If past US returns simply followed the UK profit figure, that income has probably been reported already and should not be taxed again on exit. If they were built on a cash method, it has not. The exit year is where an inconsistent history comes to light.

How is the return of your capital account taxed?

In sterling terms the answer looks obvious: you put in 300,000 pounds, you get 300,000 pounds back, there is nothing to tax. The US return does not work in sterling terms.

Your outside basis is a dollar figure built up over your whole membership. It starts with capital contributed, translated at the rate when it was paid in. It rises with your share of income as computed on US principles and with your share of partnership liabilities. It falls with drawings and with deductions and losses. Because UK taxable profit and US taxable income are not the same number, and because drawings rarely equal either, the dollar basis at exit will not match the sterling capital account. Three issues come up repeatedly:

• No basis record exists. A UK LLP does not keep one. It has to be reconstructed year by year from admission, using partnership statements, drawings schedules and capital account ledgers.
• Currency. Capital contributed when sterling stood at one rate and repaid at another can produce a dollar gain or loss with no sterling profit at all. The currency rules for partnership interests are technical, and the treatment should be decided deliberately.
• The partner capital loan. Many members fund capital with a bank loan that the firm repays directly out of the exit proceeds. For US purposes you have still received the money and repaid a personal debt, and the interest paid over the years has its own tracing analysis.

Where the capital account is repaid in instalments, the default rule lets you recover basis in full before recognising any gain on the section 736(b) element. The regulations also allow an election to spread the gain rateably over the fixed payments. Where each instalment contains both classes, a fixed-payment arrangement is allocated between section 736(a) and section 736(b) in proportion, unless the parties agree a different allocation that does not push more than the total property value into section 736(b).

Is US self-employment tax due on continuing payments after you leave?

Often it is, on the face of the Code. A section 736(a) payment to a former partner in a firm carrying on a trade or business is generally net earnings from self-employment, whether it takes the form of a distributive share or a guaranteed payment, and even though you perform no services in the year you receive it. Section 736(b) payments are not. A narrow statutory exclusion exists for certain lifelong periodic payments made under a written partnership plan, but fixed-term exit payments under a UK members' agreement will not normally meet its conditions.

Two further points matter for a UK LLP member.

First, the exclusion in section 1402(a)(13) for a limited partner's distributive share is under active dispute. The Tax Court has applied a functional test that looks at what the partner actually does, and that approach has been challenged on appeal. A member who has claimed that exclusion during membership needs to consider whether the same position is being taken on exit, and whether it is consistent with being a general partner for section 736.

Second, and more useful in practice, a US citizen resident in the UK is normally protected by the US-UK social security agreement, under which a self-employed person is subject to the social security laws of the country of residence only. The exemption is claimed on the return and supported by a certificate of coverage from HMRC. Do not assume the certificate obtained during membership covers the payout years. Self-employment tax in 2026 is 12.4% on net earnings up to the social security wage base plus 2.9% Medicare tax on all net earnings, with the 0.9% Additional Medicare Tax above the threshold, and the foreign tax credit cannot offset any of it.

How does the UK tax your final year as a member?

The UK position is simpler in structure but has two features that directly affect the US return.

Final-year profit allocation

Since 2024-25, trading profits have been taxed on a tax year basis. In the year you leave, you are taxed on your share of the LLP's profit arising between 6 April and the date you cease to be a member, apportioned from the firm's accounting periods where the year end is not 31 March or 5 April. That share is reported on the LLP's partnership return and on your own self assessment return, and it carries Class 4 National Insurance. Our guide to the SA800 partnership return explains the firm-level filing, and the guide to priority profit share covers how fixed first-slice allocations are treated.

The feature most often missed is transition profit. Members of firms with a non-aligned year end had an additional slice of profit brought into charge in 2023-24 under basis period reform, spread by default over five tax years to 2027-28. Leaving the partnership counts as ceasing your notional trade, and any transition profit not yet taxed is generally charged in full in the year of departure. That produces UK tax in the exit year on income the US taxed years ago, or will never tax as a separate item at all.

Repayment of capital and current account

Repayment of your capital account and of undrawn profits is not income. HMRC's Capital Gains Manual also confirms, in its worked examples on partners joining or leaving a partnership, that a leaving partner who simply withdraws the balance on capital account is not, for that reason alone, receiving consideration for partnership assets. Release of the tax reserve is the return of your own post-tax profit, held back by the firm to meet your liabilities.

Capital gains on goodwill

Under Statement of Practice D12, a leaving partner disposes of a fractional share of each partnership asset, normally at balance sheet value so that no gain arises. Most professional LLPs carry no goodwill in the accounts and pay nothing for it. Where the continuing members do make a payment outside the accounts for your share of goodwill, that payment is disposal consideration and a chargeable gain arises. For 2026-27 the main rates are 18% and 24%, the annual exempt amount is 3,000 pounds, and Business Asset Disposal Relief, where its conditions are met, applies an 18% rate up to the 1 million pound lifetime limit.

Post-cessation receipts

Sums that arise from the trade but reach you after you have ceased to carry it on can be taxed in the UK as post-cessation receipts, in the tax year of receipt, with an election available to carry them back to the year of cessation. Whether a particular continuing payment is a post-cessation receipt, a continuing share of profit or something else depends on the drafting of the members' agreement. The UK character matters for the US return because it fixes which UK tax year the tax belongs to, and therefore which US year can credit it.

US and UK treatment compared

Item	US / IRS treatment	UK / HMRC treatment
Profit share to leaving date	Distributive share on Schedule K-1 principles, ordinary income for the partnership year ending in your calendar year	Trading profit arising in the tax year to the leaving date, plus any untaxed transition profit
Repayment of capital	Section 736(b) distribution against dollar outside basis; gain if money exceeds basis	Not income; no capital gains disposal where only the capital account balance is withdrawn
Unbilled work in progress and fees	Ordinary income under section 736(a) or section 751	Already within trading profit under UK accounting
Goodwill payment	Ordinary under section 736(a) unless the agreement provides for goodwill, then capital	Capital gains disposal at 18% or 24%, subject to reliefs
Continuing payments after exit	Section 736(a): distributive share or guaranteed payment; you remain a partner until the last payment	Depends on legal character; may be post-cessation receipts taxed on receipt
Social security	Self-employment tax on section 736(a) amounts unless the social security agreement applies	Class 4 National Insurance on trading profit
Reporting	Form 1040 with Schedule E, Form 1116, Form 8938 and, where a category applies, Form 8865 with Schedule K-1 and Schedule P	Self assessment return with partnership pages and, where relevant, capital gains pages
Tax year	Calendar year	6 April to 5 April

How do the UK tax year and the US calendar year fit together on exit?

This is where a well-prepared exit return differs most from a transcribed one. Three timing rules collide.

The partnership year rule. You include your distributive share for the partnership tax year that ends with or within your own calendar year. If the LLP's year for US purposes ends on 31 March or 30 April, your Form 1040 has always been reporting profits on a lag.

The closing-of-the-year rule. When a partner's entire interest is liquidated, the partnership tax year closes with respect to that partner on that date. If you leave on 30 September 2026 and are paid out in full at once, your 2026 return can pick up the full partnership year to 31 March 2026 and the stub period from 1 April to 30 September 2026: eighteen months of profit in one US year. If payments continue, you remain a partner under the regulations until the last one, section 736(a) amounts follow the partnership's year, and section 736(b) amounts are taken into account when received.

The UK payment cycle. UK income tax for 2026-27 is paid through payments on account on 31 January and 31 July 2027 and a balancing payment on 31 January 2028. On a paid basis, those credits land in US years that do not contain the income.

Foreign tax credit matching in the final years

Most UK-resident members should be claiming foreign tax credits on the accrued basis, under which UK tax for a tax year ending 5 April is treated as accruing in the US calendar year that contains that date. On the facts above, UK tax for 2025-26 accrues in 2026 and UK tax for 2026-27, including tax on accelerated transition profit, accrues in 2027, when your US return may show little or no partnership income. The one-year carryback of excess credits exists for exactly this pattern, and the ten-year carryforward absorbs the remainder. The election to use the accrued basis is binding for later years, so it should be made on purpose.

The capital element needs separate care. Gain on a section 736(b) payment is generally not taxed in the UK at all where only the capital account is repaid. For a US citizen living abroad, gain on personal property is treated as foreign source only if a foreign income tax of at least 10% is actually paid on it. Untaxed UK capital repayments that produce a dollar gain are therefore likely to be US source, with no credit available and none needed. Where the UK does charge capital gains tax on a goodwill payment that the US taxes as ordinary income, the same receipt is capital on one side and ordinary on the other, and the credit has to be traced into the correct basket. The 3.8% net investment income tax is a further layer that the Code does not allow foreign tax credits to reduce.

Final Form 8865 and Schedule K-1 reporting

What you file depends on which category you have been in, as set out in the IRS guidance on Form 8865.

• Category 1 or 2 filers file for the partnership year in which the interest ends, with the Schedule K-1 marked as final where the interest has been fully liquidated, and Schedules K-2 and K-3 where required.
• Category 4. A disposition that takes a 10% or greater direct interest below 10% is a reportable event under section 6046A, reported with Schedule P. The penalty for failing to report it is 10,000 dollars, with continuation penalties after notice.
• No category. A member of a large firm with a fraction of one percent files no Form 8865. The section 736 analysis is still required, and is reported on Form 1040 through Schedule E, Schedule D and Form 8949 where there is gain, Schedule SE or the agreement exemption statement, and Form 1116.

Because you remain a partner for US purposes until the final payment, the interest also stays reportable on Form 8938 during the payout period where the thresholds are met, and any signature authority over firm accounts should be checked for the last FBAR year. IRS Publication 541 is the primary plain-language source on liquidating payments and is worth reading alongside the leaving agreement.

A worked sequence for the exit year

1. Confirm the LLP's US classification and its US tax year.
2. Establish from the members' agreement whether the exit is a redemption by the LLP or a purchase by continuing members.
3. List every payment due, with dates, and whether each is fixed or profit-dependent.
4. Decide whether the professional firm rule applies: is capital a material income-producing factor, and were you a general partner in substance?
5. Check whether the agreement expressly provides for a goodwill payment.
6. Rebuild outside basis in dollars from admission, including your share of liabilities.
7. Allocate each payment between section 736(a) and section 736(b), and identify any section 751 ordinary element.
8. Settle the self-employment tax position and renew the certificate of coverage if payments continue.
9. Map UK tax by tax year, including transition profit, to US years on the accrued basis and plan the carryback.
10. Test the Form 8865 categories for the exit year and each payout year, then Form 8938 and FBAR.

If the exit has already happened and was not reported correctly

We regularly see exits reported on the US return as a single line of foreign earned income, or not at all because the capital repayment was thought to be tax-free. If US returns were filed but an international information return was missed, a delinquent filing with a reasonable cause statement is usually the route. If income was omitted or returns were not filed, and the conduct was non-willful, the Streamlined Foreign Offshore Procedures are available to those who meet the non-residency test, and our IRS streamlined filing specialists prepare those submissions. Where the UK side also needs correcting, our UK tax team handles the self assessment amendments so that the two filings tell the same story.

Speak to us before the leaving agreement is signed

The best time to prepare the exit-year return is before the exit. Whether a goodwill payment is named in the agreement, whether continuing payments are fixed or profit-linked, and the dates on which capital is repaid all change the US result, and none of them can be changed afterwards. We do not design the terms; we prepare the returns, and we tell you in advance what each version of the terms will mean on Form 1040 and on your UK self assessment. Our US-UK tax accountants act for members of law, accounting, consulting and fund management LLPs at every stage, including those who left some years ago. To review your position in confidence, contact our cross-border team for a private consultation. Nothing is filed until you have seen the full analysis and agreed it.
