Introduction: Why Guaranteed Payments Matter to an American Partner in Britain
Guaranteed payments are fixed amounts a US partnership or multi-member LLC pays a partner for services or for the use of capital, calculated without reference to the firm's profits. Most American guides treat them as a bookkeeping question about self-employment tax and the qualified business income deduction. For a US citizen who lives in London and holds an interest in a Delaware or New York LLC, however, the choice between guaranteed payments and an ordinary profit share decides something far larger. It decides whether the same dollar is taxed once at roughly 45%, or twice at close to 70%.
The reason is a structural mismatch. The IRS sees a multi-member LLC as a transparent partnership, while HMRC generally sees it as an opaque company. Consequently, a profit share is taxed in America as it arises and taxed again in Britain as a dividend when it is paid out, with no reliable credit linking the two. Guaranteed payments for work performed in Britain behave differently on both sides of the Atlantic, and that difference is the planning opportunity this guide explains.
At TaxYork, we prepare US and UK returns for partners in consulting firms, investment managers, family businesses and professional practices who have moved to Britain while keeping their American entity. In our experience, very few of them have restructured their LLC agreement for life in the UK. This guide covers the US rules, the UK rules, the treaty, social security, timing, reporting and a full worked case study with 2026 figures.
What Guaranteed Payments Are Under Section 707(c)
The statutory definition sits in section 707(c) of the Internal Revenue Code. It says that payments to a partner for services or the use of capital, to the extent they are determined without regard to partnership income, are treated as made to a non-partner for two purposes only: inclusion in the recipient's gross income and deduction by the partnership. In every other respect, the recipient remains a partner. Therefore, a member who receives guaranteed payments is never an employee of the LLC for US purposes, receives no Form W-2 and has no income tax withheld.
The Treasury regulation at 1.707-1(c) adds the timing rule. The partner includes the payment in the tax year in which the partnership's year ends, whatever date the cash actually arrives. Furthermore, a minimum guarantee works differently: if an agreement promises a partner 30% of profits but never less than $100,000, only the shortfall the firm tops up is a guaranteed payment, and the rest remains a distributive share.
How They Differ From Distributions and a Profit Share
A distribution is simply cash leaving the partnership, and it is not taxable in itself because the partner has already been taxed on the underlying profit. A distributive share, by contrast, is the partner's allocated slice of partnership income, taxed whether or not any money changes hands. Guaranteed payments sit between the two. They are taxable as ordinary income, they reduce the partnership's profit before it is shared out, and they do not depend on whether the firm makes money at all.
The IRS partnership guidance and the Schedule K-1 instructions show where each element appears. Guaranteed payments for services go in box 4a, guaranteed payments for capital in box 4b and the total in box 4c. Meanwhile, the partner's share of ordinary business income appears in box 1. That separation matters enormously once the partner lives abroad, because each box can carry a different source, a different basket and a different UK characterisation.
How the IRS Taxes Guaranteed Payments for a Partner in the UK
The IRS taxes a US citizen on worldwide income wherever they live, so moving to London changes nothing about the obligation to file. What changes is the source of the income, and source drives the foreign tax credit and the foreign earned income exclusion.
Sourcing: Where the Work Is Done Decides Everything
A distributive share takes its source from the partnership's own income. Under section 702(b), the character and source of each item flows through unchanged, so a US consulting LLC with American clients produces US-source income for every partner, including one sitting in Mayfair. The IRS's own audit training material makes the same point: a partner in a US service partnership who performs all of their work abroad may still find a large part of their profit share is US-source and ineligible for the exclusion.
Guaranteed payments for services are different. The Tax Court in Miller (52 T.C. 752, 1969) and the Court of Claims in Carey (427 F.2d 1014, 1970) held that a guaranteed payment to a partner working outside America is compensation for personal services, sourced where the services are performed. The IRS followed those decisions, and a Tax Adviser analysis of guaranteed payments versus distributive shares summarises the three conditions: the payment must be fixed in amount, paid for services performed abroad and payable regardless of profits. Consequently, a fixed payment for work done in London is foreign-source income, even when a New York LLC pays it into a New York bank account.
The Foreign Earned Income Exclusion Option
Because guaranteed payments for services performed in Britain are foreign earned income, they qualify for the foreign earned income exclusion. For 2026 the exclusion is $132,900, and the housing exclusion for London can shelter qualifying housing costs up to a cap of $68,600. A profit share from US-source business income cannot use either relief, however long the partner has lived abroad. The statutory test in section 911 requires either a full UK tax year of bona fide residence or 330 days abroad in a 12-month period.
For high earners, the exclusion is rarely the best answer. Excluded income pushes the remaining income into higher US brackets under the stacking rule, and any UK tax paid on the excluded amount is lost as a credit. In practice, a partner earning several hundred thousand dollars of guaranteed payments taxed by HMRC at up to 45% does better with the foreign tax credit, which we turn to next.
The Foreign Tax Credit and the General Basket
UK income tax on guaranteed payments for London work is a creditable foreign tax on foreign-source income. It falls in the general category on Form 1116, alongside salary. Because UK rates of 40% and 45% exceed the top US federal rate of 37%, the credit usually wipes out the US tax on that income completely and leaves an excess credit to carry back one year or forward ten.
That excess has a second use. It can absorb US tax on other general-category foreign income, such as a UK bonus or director's fee, in the same year. In contrast, US-source profit share income sits outside the limitation fraction altogether, so even large excess credits cannot reach it unless a treaty re-sourcing rule applies. Our US tax returns for expats service models both the exclusion and the credit before choosing, because the choice binds for later years if you revoke the exclusion.
How HMRC Taxes the Same Guaranteed Payments
HMRC does not apply section 707(c). It analyses the payment by its own rules, and the starting point is how it classifies the LLC itself.
The Opaque LLC Starting Point
HMRC's International Manual at INTM180030 lists foreign entities and how HMRC classifies them, and a US LLC is generally treated as opaque, much like a company. On that view, a member's profit share is not their income as it arises. Instead, HMRC taxes the member only when the LLC distributes cash, and it treats that distribution as a dividend charged at 10.75%, 35.75% or 39.35% for 2026/27.
The Supreme Court's decision in Anson v HMRC (2015) allowed one UK-resident member of a Delaware LLC to treat his profit share as his own income and claim credit for US tax. However, HMRC regards Anson as confined to its facts and warns that claimants risk dispute. Our guide to the US LLC hybrid entity problem for UK residents covers that history in detail. The result, for most members, is that the US taxes the profit share at up to 37% as it arises while Britain taxes the same money again at 39.35% on distribution.
Why Guaranteed Payments Escape the Dividend Trap
Guaranteed payments for services do not look like a dividend to HMRC. They are a fixed reward for work, paid whether or not the LLC is profitable, and they are paid to someone performing that work in Britain. HMRC therefore taxes them as income from the work itself, and the only question is which category applies.
If the member holds an office or works under terms resembling employment, HMRC is likely to treat the payment as employment income under ITEPA 2003, taxed on the receipts basis. If the member acts more like an independent professional, the payment becomes self-employment income taxed as trading or professional profits. If the member successfully argues Anson transparency, the payment is part of their partnership profit share, because UK partnership law treats a partner's "salary" as a prior allocation of profit. All three routes produce the same essential result: income tax at the standard UK income tax rates of 20%, 40% and 45%, on income sourced in Britain, and never dividend tax on top of a US charge.
Employment or Self-Employment: The Category Still Matters
The category affects collection and National Insurance rather than the headline rate. Employment income from an overseas employer with no UK presence may require a direct collection PAYE arrangement or payment through Self Assessment, and employee Class 1 contributions can arise. Self-employment income attracts Class 4 National Insurance at 6% between £12,570 and £50,270 and 2% above that.
In our experience, HMRC rarely challenges a well-documented self-employment analysis for a genuine LLC member who shares in profits, bears risk and votes on the business. Nevertheless, the agreement should be drafted so the payment reads as a partner's reward for services, not as a wage, and the UK return should present it consistently every year.
Self-Employment Tax, National Insurance and the Totalisation Agreement
Social security is where many partners overpay, because American software and American guides assume the 15.3% self-employment tax is unavoidable.
Guaranteed Payments Are Always Self-Employment Income in US Law
Section 1402 of the Code defines net earnings from self-employment. Subsection (a)(13) excludes a limited partner's distributive share, but it expressly keeps guaranteed payments for services within the charge. That carve-back survived the January 2026 decision of the Fifth Circuit in Sirius Solutions v Commissioner, which held that a state-law limited partner with limited liability can use the exclusion for their profit share even while working in the business. The court's published opinion created a split with the Tax Court's earlier functional test in Soroban, and LLC members remain in uncertain territory.
For 2026, self-employment tax is 12.4% on net earnings up to the $184,500 wage base plus 2.9% Medicare without limit, and a further 0.9% applies above $200,000 for a single filer. Notably, at least one widely read 2026 guide still quotes the 2025 wage base of $176,100. On $400,000 of guaranteed payments, the federal self-employment charge runs to about $35,000.
The Certificate of Coverage Removes the US Charge Entirely
The US-UK totalisation agreement assigns a self-employed person to the social security system of the country where they live. Therefore, a US citizen resident in Britain who receives guaranteed payments pays UK National Insurance and owes no US self-employment tax at all, provided they hold a certificate of coverage from HMRC and attach a statement to Form 1040 each year. The IRS page on self-employment tax for businesses abroad confirms that the foreign earned income exclusion never reduces this charge, so the certificate is the only route out.
Importantly, UK National Insurance is a social security contribution rather than an income tax, so it generates no foreign tax credit. The agreement replaces the credit. Our guide to self-employment tax for Americans in the UK explains how to request the certificate from HMRC's Newcastle office rather than through the CA9107 service, which is designed for people leaving Britain.
Guaranteed Payments for Capital Follow Different Rules
Guaranteed payments for the use of capital resemble interest. They are not foreign earned income, so the exclusion cannot apply, and the IRS has never issued clear sourcing rules for them. The cautious position treats them like interest from the US payer, which makes them US-source and outside the general basket. Additionally, the section 1411 regulations treat them as net investment income, so the 3.8% surtax can apply, and UK tax charged on them is generally not creditable against that surtax.
On the UK side, a fixed return on capital paid by an opaque LLC is likely to be taxed as interest or miscellaneous income at the saving rates. Consequently, converting a profit share into guaranteed payments for capital rarely helps a UK-resident partner. The planning value lies almost entirely in payments for services performed in Britain.
Timing, the Treaty and the Hidden Risks
The rate arbitrage is clear, but three practical issues decide whether it survives contact with a real LLC agreement and an HMRC enquiry.
Matching the US Calendar Year to the UK Tax Year
Under the regulation, the partner includes guaranteed payments in the US year in which the LLC's year ends, which for most LLCs means the calendar year. Britain taxes employment income when it is paid or when the partner becomes entitled to it, and self-employment income on the tax-year basis that applies from 2024/25. Neither aligns neatly with an American calendar year.
The US foreign tax credit then adds its own timing rule. A cash-method taxpayer claims UK tax in the year it is paid, while an accrual-method claimant takes it in the US year with or within which the UK tax year ends. The 2026/27 UK year ends on 5 April 2027, so its tax accrues in the US 2027 year, not 2026. Therefore, a partner should model monthly payment dates, consider the irrevocable section 905(a) accrual election and rely on the one-year carryback where needed. Making the payments monthly and evenly, rather than as a year-end lump, keeps the two systems closest together.
The Treaty Does Not Fix the Profit Share
The US-UK income tax treaty gives Britain the primary right to tax income from work done in Britain by a UK resident, and its savings clause preserves America's right to tax its citizens. The United States then relieves the double charge through the foreign tax credit, which works smoothly for guaranteed payments because they are foreign-source income.
The treaty offers far weaker help on the profit share. That income is US-source, so the US credit cannot reach it, and HMRC's view that a dividend differs from a share of profits blocks UK relief. Article 24(6) re-sourcing can sometimes help, but it requires its own separate Form 1116 and careful argument. Our tax treaty optimisation work frequently starts by converting as much of the profit share as is commercially defensible into guaranteed payments for London services.
Permanent Establishment and Corporate Residence Risk
A partner running the business from London creates risks for the LLC as well as for themselves. If HMRC treats the LLC as opaque and the member habitually concludes contracts or manages the business from Britain, the LLC can have a UK permanent establishment, and in extreme cases its central management and control can make it UK-resident for corporation tax. Those outcomes would tax the LLC's own profits in Britain.
Guaranteed payments do not cause this risk, but they document it, because they record that valuable work is done in London. The answer is to define the London role carefully, keep strategic decisions and board meetings in America where that reflects reality, and price the payment at a level a third party would accept. Furthermore, the other members must agree, because every dollar of guaranteed payments deducted by the LLC reduces the profit shared among them.
The Reform Proposal and Other US Consequences
Two further developments affect the arithmetic, and both should be reviewed before an LLC agreement is redrafted.
HMRC's 2026 Consultation on US LLC Members
On 10 June 2026 the government published a consultation on reforming the taxation of UK-resident members of US LLCs. It proposes automatic transparency for individual members of qualifying LLCs, which would tax a profit share as it arises and allow credit for US tax. The consultation closed on 31 July 2026, and no draft legislation or start date has been published, so the current opaque treatment still applies.
If the reform is enacted, the advantage of guaranteed payments narrows for federal tax but does not vanish. The profit share would remain US-source for American purposes, so a US citizen would still need re-sourcing to credit UK tax on it. Our analysis of the reverse hybrid reform for US LLCs sets out who qualifies.
The Qualified Business Income Deduction
Guaranteed payments are never qualified business income, so they cannot benefit from the 20% section 199A deduction, which the 2025 legislation made permanent. The IRS guidance on the qualified business income deduction confirms that reasonable compensation and guaranteed payments are excluded.
For a partner in America, losing that deduction is a genuine cost. For a UK-resident partner, the loss is usually irrelevant, because UK tax credits already eliminate US tax on the converted income. Accordingly, the deduction should stay with the US-source profit share, where it still reduces a real US liability.
Reporting Both Sides Correctly
The US return carries the K-1 boxes on Schedule E, Form 1116 for the UK tax, Form 2555 if the exclusion is chosen, and the totalisation statement in place of Schedule SE. The UK return carries the income on the employment or self-employment pages, and any distributions from the opaque LLC on the foreign pages. Bank accounts in Britain that receive the payments belong on the FBAR filed with FinCEN and, above the thresholds, on Form 8938.
Missed reporting is common here. Many partners who moved several years ago have filed US returns showing their K-1 income but never claimed the credit correctly, never obtained the certificate of coverage and never reported their UK accounts. Our FBAR and FATCA reporting team regularly repairs those missed US tax returns and missed FBAR filings for LLC partners.
Case Study: A Consulting Partner Who Moved to London
The following illustrative case uses 2026 figures, an exchange rate of $1.3333 to £1 and simplified assumptions: no US state tax, no itemised deductions and full distribution of profits.
The Position Before Restructuring
Daniel is a US citizen and a 25% member of a New York consulting LLC with American clients. In 2026 the LLC earns $2,000,000 of profit, so Daniel's distributive share is $500,000, all US-source. He moved to London in 2024 and now runs the firm's European client work from there. The LLC pays him no guaranteed payments, and it distributes his full share.
US federal tax on $500,000 is about $143,800, and no UK tax can be credited against it because the income is US-source. HMRC treats the LLC as opaque, so the $500,000 distribution (about £375,000) is a dividend taxed at up to 39.35%, roughly $195,000. Daniel's total tax is therefore about $339,000, an effective rate near 68%. He also paid around $35,000 of self-employment tax, because no one had requested a certificate of coverage.
The Restructured Agreement
The members amend the operating agreement. Daniel receives $400,000 of guaranteed payments for services performed in London, and his profit percentage falls to 6.25% of the remaining $1,600,000, which is $100,000. His total economics stay at $500,000, and the other members' combined share stays at $1,500,000.
In Britain, the $400,000 (£300,000) is self-employment income. UK income tax is £121,200, about $161,600, and Class 4 National Insurance adds £7,260, about $9,700, which replaces US self-employment tax once the certificate is in place. In America, the US tax on $500,000 is still about $143,800 before credits. The general-basket limitation allows a credit of 400/500 of that, about $115,000, leaving roughly $28,800 of US tax on the US-source $100,000 profit share and an excess UK credit of about $46,600 to carry forward. The $100,000 distribution then bears UK dividend tax of about $39,400.
The Result
Daniel's total tax falls from about $339,000 to about $229,800, a saving of roughly $109,000 a year, and his effective rate drops from 68% to 46%. Adding the self-employment tax recovered through the certificate, the annual improvement exceeds $140,000. In addition, the three-year refund window let him reclaim self-employment tax for 2023 and 2024 on amended returns.
The case also shows the limits. The remaining $100,000 profit share is still double-taxed, the payment must be defensible as arm's-length pay for genuine London work, and the excess credit only has value if Daniel has other general-category income to absorb it.
How TaxYork Can Help
TaxYork prepares both the US and the UK returns for American partners in US LLCs and partnerships, so the same figures, dates and characterisations appear on both sides. We review the operating agreement, model the split between guaranteed payments and profit share across both tax systems, and quantify the foreign tax credit, exclusion and National Insurance position before any change is made.
We also request the certificate of coverage, prepare the totalisation statement, file Form 1116 with any re-sourcing claim and complete the UK employment, self-employment or foreign pages. Where earlier years were filed incorrectly, we correct them through amended returns, restore missed FBAR and Form 8938 reporting, and reclaim overpaid self-employment tax within the refund window. Our cross-border team works with high-net-worth partners, fund principals and business owners who expect both returns to be right the first time.
Conclusion
For an American partner in Britain, guaranteed payments are not a footnote on Schedule K-1. They are the main tool for turning US-source profit, taxed twice at close to 70%, into foreign-source pay for London work, taxed once at Britain's income tax rates with a matching US credit. They also unlock the foreign earned income exclusion where it helps, and, with a certificate of coverage, they carry no US self-employment tax at all.
However, the structure only works when the LLC agreement, the UK classification, the timing of payments and both returns tell the same story. The reform consultation may soften the dividend trap in future, but it has not yet become law. Therefore, any UK-resident member of a US LLC should review their agreement now, before the next profit allocation is fixed.
