Does an employer pension contribution reduce my GILTI or net CFC tested income?

Generally yes, to the extent the contribution is deductible under US tax principles in that year. It is entered as a deduction on Schedule I-1 line 5, reducing tested income on line 6. Because section 404A cannot apply to a plan for a US citizen director, the timing of the US deduction must be checked under the general section 404 rules, and it may not match the UK accounts or the UK corporation tax deduction.

Where do employer pension contributions go on Form 5471?

There is no dedicated pension line. The contribution appears within expenses on Schedule C, the US GAAP income statement in functional currency. Any difference between the book charge and the US tax deduction is adjusted on Schedule H, normally on line 2i with a statement. The allowable deduction then reduces tested income on Schedule I-1, and the Schedule M treatment needs a documented case-by-case decision.

Is a contribution to my SIPP or SSAS reported on Schedule M?

Schedule M has five specific related-person columns, and a pension scheme is not obviously any of them. Some preparers treat the contribution as compensation to the director on line 21 in column (b); others conclude it is outside Schedule M. The instructions do not address pensions directly, so the decision should be made case by case and documented. If reported as another amount paid, line 29 requires a statement.

Can my UK company deduct pension contributions it pays for me as a director?

Usually yes. HMRC's BIM46035 says employer contributions to a registered pension scheme for a director are allowable unless there is a non-trade purpose, and the overall package must be wholly and exclusively for the trade. The deduction is given in the period the contribution is paid, not when accrued, and very large increases in contributions can require the deduction to be spread over several periods.

Is the employer contribution taxable to me in the US as a US citizen living in the UK?

Article 18(5) of the US-UK treaty can stop employer contributions being treated as US taxable income for a US citizen resident in the UK whose UK employment is borne by a UK resident employer. The relief is limited to contributions qualifying for UK relief, capped at what a corresponding US scheme would allow, and depends on competent authority agreement. Form 8833 disclosure may be required for the treaty position.

Does the UK annual allowance limit what my company can contribute?

The annual allowance limits what you can receive without a personal tax charge, not what the company can deduct. GOV.UK states it is 60,000 pounds for the current tax year, counts employer contributions, allows carry-forward from the previous three years, and is tapered where threshold income exceeds 200,000 pounds and adjusted income exceeds 260,000 pounds. Contributions above your allowance trigger an annual allowance charge on you.

Form 5471: Employer Pension Contributions for US Directors

Form 5471 does not have a dedicated line for pension contributions, but when a US citizen's UK limited company pays large employer contributions into a SIPP or SSAS for its director, those payments flow straight through the return: they reduce the profit shown on Schedule C, they feed the earnings and profits calculation on Schedule H, they can reduce tested income on Schedule I-1, and they raise a related-party question on Schedule M. The short answer is that the contribution is usually a genuine deduction for the company in the UK, but the US side of the deduction has to be built on US tax principles, and the timing and amount do not automatically match what the UK accounts show.

This guide works through the company side first, because that is where we see the errors in the returns we prepare for owner-directors. The personal side, meaning whether the director is taxed in the US on the contribution, gets one short section only; we cover that topic in depth in a separate post on employer contributions to a UK SIPP. Everything below follows the current Instructions for Form 5471 at https://www.irs.gov/instructions/i5471, revised December 2025.

Why do employer pension contributions matter for Form 5471?

An employer pension contribution is a payment by the company, not by the director, into a registered pension scheme for the director's benefit. For a UK owner-manager it is a standard extraction route alongside salary and dividends, because HMRC generally allows it as a corporation tax deduction.

For a US citizen who controls the company, the same payment also sits inside a controlled foreign corporation. Category 4 of Form 5471 covers a US person who had control of a foreign corporation during its annual accounting period, so a US citizen owning more than half of a UK limited company is usually a Category 4 filer. If the same person also meets Category 5a as a US shareholder of the CFC, the filer checks Category 4 only on the form, while still completing the schedules the filing chart requires. Filing requirements and updates are at https://www.irs.gov/form5471.

How do the contributions appear on Schedule C of Form 5471?

Schedule C is the income statement. The instructions say to report all information in the foreign corporation's functional currency in accordance with US GAAP and to translate using US GAAP translation principles. For a UK limited company, the functional currency is usually sterling, and the UK statutory accounts are normally prepared under UK accounting standards rather than US GAAP, so the Schedule C figures are a GAAP-conformed version of the UK profit and loss account, not a copy of it.

The employer pension contribution sits inside the company's expenses on Schedule C. There is no specific pension line, so it is carried within the ordinary expense lines along with salaries and other employment costs. Two points matter in practice.

Book timing. The UK accounts usually recognise the pension cost on an accruals basis, so a contribution agreed before the year end but paid after it can appear as an expense in the accounts. Schedule C follows the book figure under US GAAP, so the starting point is the accounting charge, not the cash paid.
Tax line separation. Schedule C line 21 is for income tax expense under US GAAP, split between current and deferred. The corporation tax saving produced by the pension deduction shows up there, not netted into the pension expense.

The Schedule C figure can therefore differ from the deduction HMRC allows for the same year. That gap is not an error; it signals that a Schedule H adjustment may be needed.

How do pension contributions affect E&P on Schedule H?

Schedule H reports the foreign corporation's current-year earnings and profits for US tax purposes. The instructions say the amounts on lines 1 through 5c are entered in the CFC's functional currency, and that adjustments required by Regulations section 1.964-1(b) and (c) are made to the line 1 net book income to arrive at current-year E&P. Those adjustments conform foreign book income to US GAAP and to US tax accounting principles, and they can be positive or negative.

This is where an employer pension contribution needs genuine thought, because US tax accounting principles have their own rules for deferred compensation. Section 404A of the Internal Revenue Code allows a special regime for qualified foreign plans, and it expressly governs how such plans affect the earnings and profits of a foreign corporation. However, the statutory definition at section 404A(e) requires that 90 percent or more of the amounts taken into account under the plan be attributable to services performed by nonresident aliens whose compensation is not subject to US tax. A SIPP or SSAS funded for a single US citizen director cannot meet that test, so section 404A is not available for the director's own scheme.

That pushes the analysis back to the general deferred compensation rules in section 404. Under section 404(a)(5), for a plan that is not a US qualified plan, the employer's deduction falls in the taxable year in which an amount attributable to the contribution is includible in the employee's gross income, and where more than one employee participates, only if separate accounts are maintained for each employee. Inclusion in the US director's income depends partly on the treaty position discussed later, so the E&P deduction cannot simply be lifted from the UK accounts; we analyse it case by case and document it every year.

If the analysis supports a deduction in the same year and amount as the book charge, no Schedule H adjustment is needed for the pension cost.
If US principles defer or deny part of the deduction, the difference is an adjustment to book income. Where it does not fall within the specific items on lines 2a through 2h, the instructions route it to line 2i, which requires a separate statement listing the additional adjustments.
Any difference between the income tax expense on Schedule C line 21 and the taxes that reduce US E&P belongs on line 2g, so the tax effect of the pension deduction is reconciled separately from the deduction itself.

Does an employer pension contribution reduce tested income and the net CFC tested income inclusion?

Usually yes, to the extent the contribution is deductible under US tax principles in that year. Schedule I-1 is where the CFC's tested income is computed. The instructions describe line 1 as the CFC's gross income, line 2 as the exclusions in Regulations section 1.951A-2(c), and line 5 as the deductions, including taxes, properly allocable to gross tested income under section 951A(c)(2)(A)(ii) and Regulations section 1.951A-2(c)(3). Line 6 is tested income or tested loss, converted from functional currency to US dollars at the CFC's average exchange rate for the year.

A deductible employer pension contribution therefore sits on line 5 and reduces line 6. For a trading company with active income, that is a direct reduction of the amount that flows to the shareholder's annual inclusion. If the US analysis defers the deduction, line 5 is lower in the contribution year and higher in the year the deduction is eventually allowed.

Terminology has changed. Section 70323 of Public Law 119-21 renamed global intangible low-taxed income as net CFC tested income in section 951A and removed the net deemed tangible income return, effective for taxable years beginning after 31 December 2025. The December 2025 Form 5471 instructions, which cover 2025 years, still use the GILTI and section 951A inclusion language, and still refer to qualified business asset investment, because those rules applied for 2025. For 2026 years onward, the shareholder's inclusion is net CFC tested income and the tangible asset offset no longer applies, so every deductible pound of expense, including pension contributions, matters more. The shareholder-level computation is made on Form 8992, described at https://www.irs.gov/forms-pubs/about-form-8992.

Two related points often decide whether the pension contribution changes the US tax bill at all.

Section 962 election. The instructions note that certain noncorporate US shareholders may elect under section 962 to be taxed at corporate rates on section 951(a) and section 951A amounts, so as to claim a credit for foreign taxes paid by the CFC. A pension deduction lowers both the tested income and the UK corporation tax attributable to it, so the effect on a 962 computation is not one-for-one.
High-tax exclusion. The instructions refer to the high-tax exclusion in Regulations section 1.951A-2(c)(7), under which qualifying high-taxed tested income can be excluded. Whether UK income qualifies depends on the effective foreign rate computed under US principles. A pension deduction that is taken in different years in the UK and the US can move that effective rate up or down, so the election needs to be tested after the pension adjustment is settled, not before.

Does a pension contribution to a SIPP or SSAS go on Schedule M?

Schedule M reports transactions between the CFC and its shareholders or other related persons, and the instructions say every Category 4 filer must file it. The schedule does not ask about related persons in the abstract; it has five specific columns: (b) the US person filing the return, (c) any domestic corporation or partnership controlled by that person, (d) any other foreign corporation or partnership controlled by that person, (e) any other 10 percent or more US shareholder of the CFC, and (f) any 10 percent or more US shareholder of a corporation controlling the CFC. Amounts are translated at the average exchange rate for the year, and an accrual-method company uses accrued payments and receipts.

A registered pension scheme is not obviously any of those five persons. Neither a SIPP nor a SSAS is normally a corporation or partnership controlled by the director, or a US shareholder of the company, so on that reading the contribution is not a payment to a column (b) to (f) person. The opposing view is that the contribution is remuneration for the director's services paid for the director's benefit, and the closest line is line 21, compensation paid for technical, managerial, engineering, construction or like services, in column (b). The director's salary is clearly a column (b) item.

The current instructions do not address pension contributions on Schedule M, so we do not state a single rule. In our practice we review the scheme documents, the board minute and the payroll treatment case by case. Where the conclusion is that the amount belongs on Schedule M other than as compensation, line 29 is for other amounts paid, and the instructions require an attached statement describing the type of payment, analysed across the columns and tied to a totals line. Whatever the conclusion, the reasoning belongs in the workpapers, because Schedule M is the schedule an examiner reads first when looking at value leaving a controlled company.

How does HMRC treat employer contributions for a director?

On the UK side the starting point is simpler. HMRC's Business Income Manual at BIM46035 says a pension contribution by an employer to a registered pension scheme for any director or employee is an allowable expense unless there is a non-trade purpose for the payment: https://www.gov.uk/hmrc-internal-manuals/business-income-manual/bim46035. Where the contribution is part of a remuneration package paid wholly and exclusively for the purposes of the trade, it is deductible.

The risk area for a controlling director is an excessive package. BIM46035 says that where the remuneration is excessive for the value of the work done, HMRC considers whether the overall package, not just the pension contribution, was paid wholly and exclusively for the trade, and only the non-trade part is disallowed. A package comparable with that paid to unconnected employees doing work of similar value is accepted.

Timing differs from the accounts. BIM46010 at https://www.gov.uk/hmrc-internal-manuals/business-income-manual/bim46010 explains that employer contributions to registered pension schemes are deductible for the period of account in which they are paid, not when they are accrued, so the corporation tax computation adds back the accounting charge and deducts the cash paid. Spreading of the deduction over several periods can be required where contributions increase by more than 210 percent from one period to the next, unless the increase is below 500,000 pounds; the detail is in the Pensions Tax Manual at PTM043400.

The annual allowance limits what the director can receive without a personal tax charge, not what the company can deduct. GOV.UK at https://www.gov.uk/tax-on-your-private-pension/annual-allowance states the annual allowance is 60,000 pounds for the current tax year, that it counts contributions by anyone including an employer, that unused allowance can be carried forward from the previous three tax years, and that a tapered allowance applies where threshold income exceeds 200,000 pounds and adjusted income exceeds 260,000 pounds. A lower money purchase annual allowance applies once a pension has been flexibly accessed.

What about the director personally? The treaty in one section

Because we have a separate post on employer contributions to a UK SIPP, this is a summary only. Article 18(5) of the US-UK income tax treaty, at https://home.treasury.gov/system/files/131/Treaty-UK-7-24-2001.pdf, applies where a US citizen who is resident in the UK exercises an employment in the UK, the income is taxable in the UK and borne by a UK resident employer, and the individual is a member of a UK pension scheme. In that case, contributions made by the employer during that period and attributable to the employment are not treated as part of the employee's taxable income in the US.

The relief has limits written into the paragraph. It applies only to the extent the contributions qualify for UK tax relief, it cannot exceed the relief the US would give its residents for a generally corresponding US scheme, and it applies only if the US competent authority has agreed that the scheme generally corresponds to a US scheme. Article 1 of the treaty lists Article 18 among the provisions that continue to benefit US citizens despite the saving clause. A US citizen director who lives in the US and runs a UK company remotely does not meet the UK residence condition in Article 18(5), so the analysis is different.

Where a return position relies on the treaty to override the Code and reduce tax, the Form 5471 instructions remind filers that Form 8833 is generally required, subject to the exceptions listed with Form 8833 itself, and that failure to disclose can carry a 1,000 dollar penalty, or 10,000 dollars for a C corporation, under section 6712. Whether an exception applies to a particular pension position is part of the personal-side review: https://www.irs.gov/forms-pubs/about-form-8833. The personal position matters to the company side too, because under section 404(a)(5) the timing of the company's US-principle deduction is tied to inclusion in the employee's income.

Salary, dividend or pension: how does the choice change Form 5471?

Salary is deductible for the company, reduces Schedule C profit and tested income, and is reported on Schedule M line 21 in column (b). For the director it is earned income in both countries.
Dividends are not deductible. They do not reduce tested income. The instructions limit Schedule M line 25 to dividends not previously taxed; distributions of previously taxed earnings are tracked on Schedule J and Schedule P instead.
Employer pension contributions are deductible in the UK when paid and potentially deductible under US principles, but the US timing depends on section 404 and the director's own inclusion, and the Schedule M treatment needs a documented decision.

Worked scenario: a US director's SIPP contribution on Form 5471

Illustration only. All figures are assumed and simplified, and an average exchange rate of 1 pound = 1.30 US dollars is an assumption for the year. Ella is a US citizen living in London. She owns 100 percent of a UK consultancy limited company with a 31 December year end, so she is a Category 4 filer. The company has revenue of 520,000 pounds, overheads of 60,000 pounds and pays Ella a salary of 30,000 pounds. On 20 December the company pays a 60,000 pound employer contribution into her SIPP. Ella has no carry-forward and her income is assumed to keep her outside the taper, so the contribution sits within her 60,000 pound annual allowance for that tax year.

UK computation. Profit before the pension contribution is 430,000 pounds. Because the contribution was paid within the period, BIM46010 allows the 60,000 pound deduction in this period, giving 370,000 pounds before corporation tax. The package is commercial for a sole fee-earner running the business, so the wholly and exclusively test is met.
Schedule C. The US GAAP income statement shows the 60,000 pound pension cost within expenses and the corporation tax charge on line 21, in sterling and translated to dollars.
Schedule H, outcome A. If the US analysis supports a deduction in the same year, no pension adjustment is needed and current-year E&P starts from book profit after tax. Pre-tax, the pension saves 60,000 pounds, or about 78,000 dollars at the assumed rate.
Schedule H, outcome B. If US principles defer the deduction, a positive adjustment of 60,000 pounds is entered on line 2i with a statement, and the deduction is recognised in the year the timing rule allows.
Schedule I-1. In outcome A, line 5 includes the 60,000 pound deduction and line 6 tested income before taxes falls from 430,000 pounds to 370,000 pounds, roughly 559,000 dollars down to 481,000 dollars at the assumed rate. In outcome B, line 6 stays at the higher figure for this year.
Schedule M. The 30,000 pound salary goes on line 21 in column (b). The SIPP contribution is reviewed case by case; the decision and reasoning are recorded in the workpapers, and if it is reported as another amount paid, line 29 carries the required statement.

Form 5471 checklist for employer pension contributions

Confirm the scheme type, SIPP or SSAS, and whether any other employees participate, because section 404(a)(5) requires separate accounts where more than one employee participates.
Reconcile the UK accounts charge, the corporation tax deduction on a paid basis and any spreading under PTM043400.
Document the US-principle deduction analysis, noting that section 404A is not available for a scheme benefiting a US citizen director.
Enter any timing or amount difference on Schedule H, using line 2i with a statement where it does not fit the specific lines.
Carry the allowable deduction to Schedule I-1 line 5 and re-test any high-tax exclusion or section 962 election afterwards.
Decide and document the Schedule M treatment of the contribution, and report salary in column (b) on line 21.
Confirm the director's personal position under Article 18(5), and consider Form 8833.

Common failure modes we see

Copying the UK profit and loss account straight onto Schedule C and Schedule H, so the pension cost is deducted for US purposes in the year it was accrued even though nobody has tested the US timing rule.
Assuming section 404A applies because the scheme is a recognised UK pension, when the nonresident alien test in section 404A(e) rules it out for a US citizen's own plan.
Leaving Schedule M blank for the director entirely, when at minimum the salary belongs on line 21 in column (b).
Relying on Article 18(5) for a director who has moved back to the US, when the paragraph requires UK residence and UK-taxable employment.
Paying a contribution just after the company's year end and expecting a UK deduction in the earlier period, when BIM46010 allows the deduction only in the period of payment.

Getting the Form 5471 pension reporting right

An employer pension contribution is one of the most efficient ways for a UK owner-director to take value out of a company, and for a US citizen it can also reduce the annual US inclusion. But on Form 5471 it touches four schedules, it depends on a US deduction analysis that the UK accounts do not answer, and it interacts with the director's personal treaty position. In the returns we prepare, we reconcile the UK paid-basis deduction, the US GAAP book charge and the US-principle E&P and tested income figures every year, and we document the Schedule M decision. If your company has made a large SIPP or SSAS contribution for you, our Form 5471 preparation service can work through each schedule before the return is filed.
