UK Benefits in Kind on Your US Tax Return
Your P11D is a UK measure, not a US one. How company cars, medical cover, pensions, loans, relocation and childcare are treated on a US return, benefit by benefit.
Your P11D is a UK measure, not a US one. How company cars, medical cover, pensions, loans, relocation and childcare are treated on a US return, benefit by benefit.
A UK benefit in kind is valued under UK rules, and that figure is not automatically the number that belongs on your US return. The United States taxes compensation broadly, so a benefit fully taxed, partly taxed or entirely exempt in the UK may still be US taxable income, measured under US rules rather than HMRC's. The task is to take the package apart benefit by benefit, settle the US treatment of each, then line the UK tax year up against the US calendar year.
Rates and thresholds here are as at 6 October 2026 and reflect the 2026-27 UK tax year. The UK Budget is on 28 October 2026 and may change them.
UK benefit valuation is formulaic: a company car is list price times a CO2-based percentage, private fuel a fixed multiplier, a cheap loan HMRC's official rate. None of those formulas exists in US law. IRS Publication 15-B starts from the opposite end — any fringe benefit is taxable and must be included in pay unless the law specifically excludes it, and each exclusion carries its own conditions, ceiling and measure.
So three things can happen to any P11D line: the US taxes it but measures it differently; the US excludes it; or the US taxes something the UK left alone. For the employer-side mechanics see our complete UK employer reporting guide to P11D and benefits in kind; this article is the employee's US return.
UK. The cash equivalent is list price multiplied by an appropriate percentage, which for 2026-27 runs from 4% for a zero-emission car to a 37% maximum (HMRC tables). Private fuel not fully reimbursed carries a separate charge: the 2026-27 multiplier is £29,200, times the same percentage. Charging an employer-provided electric car creates no fuel charge; pool and business-only cars sit outside the charge.
US question. Personal use of an employer-provided vehicle is compensation, valued under US rules — general fair market value, the annual lease value table, the cents-per-mile rule or the commuting rule, each with its own conditions. Business use may instead be a working condition fringe. The US figure is built from the mileage split and the vehicle's value, so it rarely matches the P11D. Our comparison of company cars versus a car allowance covers the UK side.
UK. Taxable, with Class 1A National Insurance for the employer. A narrow band is exempt — one health screening a year, eye tests for screen work, flu jabs, treatment for a work-caused injury, and up to £500 of return-to-work costs after a qualifying absence (HMRC).
US question. Whether the arrangement is coverage under an accident or health plan. Employer contributions to accident or health insurance, and employer payments or reimbursements of medical expenses, are excludable from US wages. This is the most common favourable divergence: a figure taxable on your P11D often carries no US tax. Not automatic — a cash medical allowance is a different animal from insured cover.
UK. Contributions to a registered scheme are exempt and not reported on the P11D; HMRC's helpsheet HS207 treats the expense of providing a pension, annuity or lump sum on retirement or death as non-taxable.
US question. Without relief, a foreign employer's contribution to a scheme that is not US-qualified is compensation. The bridge is Article 18(5) of the US-UK income tax convention. Where a US citizen resident in the UK exercises a UK employment taxable in the UK and borne by a UK employer or UK permanent establishment, and is a member of a UK pension scheme, employer contributions and benefits accrued during that period are not treated as part of the employee's taxable income in computing US taxable income. Two conditions are routinely missed: it applies only to the extent the contributions or benefits qualify for UK tax relief, and only where the US competent authority has agreed the scheme generally corresponds to a US scheme. Relief is capped at what the US would allow for a corresponding US plan.
This is the largest divergence in most packages; our guide to US tax on UK pensions and SIPPs goes further.
UK. Cover through a registered pension scheme generally falls within the exempt treatment for retirement and death benefits, so nothing appears on the P11D.
US question. Whether it is group-term life insurance for US purposes. If so, coverage up to $50,000 is excludable and the cost of coverage above that is included in wages. A lump-sum promise outside an insured group scheme is analysed differently. Either way the amount is set by US rules, not the UK premium.
UK. Reportable if the combined balance owed reaches £10,000 at any point in the tax year, valued at HMRC's official rate of interest, 3.75% from 6 April 2026. Loans cannot be payrolled.
US question. Compensation-related below-market loans fall under section 7872, which does not apply on any day the aggregate balance between borrower and lender is $10,000 or less, unless avoiding federal tax is a principal purpose. The US measure is forgone interest at the applicable federal rate, in dollars — so two thresholds that look alike and two different rates produce two different numbers from one loan.
UK. A cash equivalent covering the accommodation plus running costs — council tax, utilities, cleaning, repairs, furniture. Job-related exemptions are narrow, and accommodation cannot be payrolled.
US question. The lodging exclusion is tight: lodging must be on the employer's business premises, for the employer's convenience, and accepted as a condition of employment. Most expatriate housing fails at least one leg. If you claim the FEIE, employer-provided housing instead feeds the foreign housing exclusion — a different and often better route.
UK. Up to £8,000 of qualifying costs is exempt where the move is genuinely for work, the new home is reasonably close to the workplace and the old one was not, and the costs are paid by the end of the tax year after the one the job started in (HMRC).
US question. There is no equivalent. Publication 15-B states the exclusion for moving expense reimbursements is permanently eliminated for most employees as of 2026, with narrow exceptions for Armed Forces members moving under orders and certain intelligence community employees. Expect the whole package to be US compensation, UK-exempt slice included.
UK. Exempt where the employer pays or reimburses a subscription to a body on HMRC's List 3 of approved professional organisations and learned societies.
US question. Whether it is a working condition fringe — a cost of doing your job rather than a personal benefit. A licence you must hold to perform the role sits differently from a general-interest subscription; this one turns on the facts.
UK. Vouchers and directly contracted childcare are closed to new joiners, but existing participants keep £55 a week for basic rate, £28 for higher rate and £25 for additional rate taxpayers. Workplace nurseries meeting HMRC's conditions are exempt (HMRC).
US question. Whether the arrangement qualifies as a dependent care assistance programme. The US exclusion for 2026 is $7,500 ($3,750 if married filing separately), raised from $5,000. Whether a UK scheme meets the US plan requirements turns on its terms, not its UK status.
UK. Recreational facilities generally available to employees and their families, used mainly by people whose right to use them is employment-related, are exempt; a commercial gym membership for one executive is not. A trivial benefit costing £50 or less is exempt if it is not cash, not a reward for work and not contractual — with a £300 annual cap for close-company directors.
US question. The on-premises athletic facility exclusion covers a facility the employer operates on premises it owns or leases where substantially all use is by employees, spouses and dependent children; off-site memberships generally do not qualify. Small items may be de minimis fringes — a rule with no fixed dollar figure that never covers cash.
| Benefit | UK treatment (2026-27) | US question to settle |
| --- | --- | --- |
| Company car, private use | List price × percentage (4% to 37%) | Personal-use value under US valuation rules; business use a working condition fringe |
| Private fuel | £29,200 × same percentage; nil if reimbursed | Value of fuel for personal use; electricity differs |
| Private medical insurance | Taxable; Class 1A for employer | Accident or health plan coverage? Often not US taxable |
| Employer pension contributions | Exempt; not on the P11D | Article 18(5): UK relief, scheme agreed to correspond? |
| Life assurance / death in service | Generally exempt via registered scheme | Group-term life insurance? First $50,000 excludable |
| Interest-free or cheap loan | Official rate 3.75% at a £10,000 balance | Section 7872 forgone interest at the AFR above $10,000 |
| Living accommodation | Cash equivalent plus running costs | Lodging exclusion, or the foreign housing exclusion |
| Relocation payments | £8,000 exempt if paid in time | No exclusion for most employees as of 2026 |
| Professional subscriptions | Exempt if the body is on List 3 | Working condition fringe? Depends on body and role |
| Childcare vouchers or nursery | £55 / £28 / £25 a week by band | Dependent care assistance programme? $7,500 for 2026 |
| Gym and wellbeing | Exempt if generally available | On-premises athletic facility exclusion only |
| Small gifts | £50 or less; £300 director cap | De minimis fringe — no fixed limit, never cash |
Your UK employer lends you £60,000 interest-free in April 2026, outstanding all year, and pays £12,000 of qualifying relocation costs in time.
UK. The loan exceeds £10,000, so the cash equivalent is £60,000 × 3.75% = £2,250, reported on the P11D. Of the relocation costs, £8,000 is exempt and £4,000 reportable. UK taxable benefits: £6,250.
US. The loan falls within section 7872, but the US amount is forgone interest at the applicable federal rate, in dollars — a different rate, currency and figure. On relocation there is no £8,000 equivalent, so the dollar value of the whole £12,000 is compensation.
The shape matters more than the arithmetic: £6,250 of UK taxable benefit corresponds to a US figure built from separate rules — here a larger one, because the relocation exemption does not travel.
In force. Employers may voluntarily payroll most benefits, putting the cash equivalent through PAYE in real time instead of on a P11D. Registration must happen before the tax year starts, and the window for 2026-27 closed on 5 April 2026. Accommodation and beneficial loans cannot be payrolled. Where benefits are payrolled the employer still submits a P11D(b), still pays Class 1A, and must give employees written details of payrolled benefits by 1 June after the tax year ends (HMRC).
Announced, not in force. HMRC has announced mandatory reporting of benefits in kind through payroll software and Real Time Information. Company cars, car fuel, vans, van fuel and employer-provided medical benefits move into the Full Payment Submission from April 2027; most remaining benefits follow from April 2028; loans and accommodation are to be confirmed. Detailed scope sits in secondary legislation expected at Budget 2026, and HMRC has said it will not charge inaccuracy penalties for mandatory-payrolling errors in 2027-28 RTI returns absent deliberate non-compliance (HMRC policy paper).
This changes paperwork, not principle — but as benefits move into payroll, their values sit inside monthly payroll figures rather than on a P11D.
Three documents carry it: your P60, due by 31 May, with payrolled benefits inside the pay figure; your P11D, due by 6 July, for benefits not payrolled; and your payrolled-benefits statement, due by 1 June. All three run 6 April–5 April. Your Form 1040 runs the calendar year.
1. Collect every monthly payslip for the calendar year, not just the P60 — payslips are the only document that splits a UK tax year into months.
2. For payrolled benefits, read the monthly value off the payslip and sum January to December.
3. For annual cash equivalents such as a car or a loan, apportion by the days available in each calendar year, and keep the workings.
4. Rebuild each amount under US rules, which may mean discarding the UK value entirely.
5. Convert consistently, using one documented method across the whole return and across years.
6. Record which UK tax came through PAYE each month and which was settled later by Self Assessment.
UK income tax on employment income, benefits included, is creditable. Article 24 of the treaty requires the United States to allow a citizen or resident a credit for income tax paid or accrued to the United Kingdom, subject to the limitations of US law — in practice Form 1116, usually in the general category.
Timing is where benefits cause trouble. IRS Publication 514 explains that a cash-method taxpayer claims the credit in the year the tax is paid but may elect the year of accrual by checking the "Accrued" box on a timely filed original Form 1116, with foreign taxes generally accruing on the last day of the foreign tax year. Where benefits are partly collected through PAYE and partly settled by Self Assessment the following 31 January, that choice changes which US year the credit lands in — and once made, it governs later years.
Publication 514 is also explicit that you cannot credit foreign taxes paid on income excluded under the foreign earned income exclusion. And benefits are earned income: the Form 2555 instructions bring noncash income such as a home or car, and allowances or reimbursements, within foreign earned income. Electing the exclusion therefore sweeps benefits into it and strips the matching UK tax out of your credit pool — a trade-off worth modelling, starting with our comparison of FEIE versus the foreign tax credit.
Ask once, in writing, and ask for detail rather than a summary:
Keep these with your record of exchange rates used, Self Assessment calculations and payment dates, and — if your employer operates one — the tax equalisation computation, which changes who bears the tax on each benefit.
Most of this is manageable once a year with good records. It stops being manageable when benefits are large relative to salary, when a pension scheme's treaty position has never been established, when a relocation or accommodation package straddles two calendar years, or when a tax equalisation policy sits on top. One wrong assumption there compounds across several returns.
If your package carries more than two or three reportable benefits, have the first year's analysis done properly and then reuse it. At Next Tax Source an ACCA-qualified accountant handles the UK side and a licensed CPA or Enrolled Agent reviews and signs off the US return, so both halves are reconciled by people who can see both. See what that costs on our pricing page, or book a consultation and bring your P60, your P11D and a payslip.
