(UNITED KINGDOM) — HMRC allows some newly UK resident employees to cut their UK tax bill through Overseas Workday Relief, but the relief hinges on workday records, residence history and a claim made in Self Assessment, not on travel alone.

OWR applies to employment income linked to duties performed outside the UK in a tax year when the employee is a “qualifying new resident”. HMRC says the relief can reduce UK tax on overseas workdays, but it is not automatic. The employee must meet the conditions, identify the qualifying income and enter the claim correctly on the tax return.

Cross-border workers face the sharpest risk at filing time. A technically eligible employee can still fail to support a claim if daily records do not show where duties were physically performed, how pay was allocated and how the relief amount was calculated.

Eligibility and Residence Requirements

Eligibility starts with residence history. HMRC says an employee qualifies for the OWR regime in a tax year if that person is UK resident in the year, was non-UK resident for a continuous period of at least 10 tax years immediately before it, and is not disqualified for the year.

That status can continue beyond the first year. HMRC says a qualifying new resident can remain eligible in the following three-year period, allowing OWR for up to four tax years. Long-term UK residents who travel abroad for business do not qualify simply because they have overseas trips.

Residence analysis still matters even before any OWR calculation begins. Employees returning after a long absence must still check their position under the Statutory Residence Test. Some dual residents may also face treaty questions, but HMRC says treaty residence in another country does not change UK residence status under the Statutory Residence Test.

Income Covered by OWR

Income covered by OWR reaches beyond salary. HMRC says it can apply to earnings and amounts treated as earnings, including benefits in kind, certain employment-related securities income and third-party employment income. Bonuses, share options, restricted stock units and deferred compensation can all fall into the review.

Timing complicates that review. A bonus paid in 2026 may relate to duties carried out earlier. A share award may vest after a move to the UK but still relate partly to pre-arrival and post-arrival periods. Each amount has to be apportioned between UK duties and overseas duties.

Filing the Claim

The claim itself must go into the tax return. HMRC says an OWR election must be made in the employee’s Self Assessment return for the qualifying year, and the amount of relief claimed must be quantified in that return. Taxpayers cannot assume HMRC will calculate the figure for them.

Residence pages also sit at the centre of the filing. The SA109 supplementary pages record residence status and related claims alongside the SA100 return. HMRC updated the page for the 2025–26 tax year on April 6, 2026, and its employment residence helpsheet says OWR claims for income earned from 2025–26 and later must use the “residence and foreign income and gains regime etc” pages of the return.

Workday Tracking: The Critical Evidence

Workday tracking usually decides whether a claim survives scrutiny. Employees need a daily calendar showing where they physically performed duties, separating UK workdays, overseas workdays, travel days, holidays, sick days, weekends, non-working days and days with mixed duties.

Evidence should back up that calendar as the year progresses. HMRC’s practical trail can include passport stamps, flight bookings, boarding passes, hotel invoices, travel system records, Outlook or Google calendar entries, timesheets, assignment letters, office access records and expense claims. A spreadsheet built at year-end carries less weight if nothing supports it.

Physical location, not commercial geography, drives the analysis. Work done from London for a client in New York, Dubai or Singapore remains UK work. Work performed in Paris, Mumbai, New York or Dubai may count as overseas duties, subject to the full OWR rules.

Split-Year Treatment and the New Cap

Split-year treatment can narrow the period even more. HMRC says that where the tax year of an OWR election is a split year, the relief applies only to employment income relating to the UK part of the year. Someone who arrives in December 2025 and qualifies for split-year treatment does not test the whole tax year in one block.

Employees also need to weigh the financial limit that now applies. From April 6, 2025, HMRC says OWR is capped at the lower of 30% of qualifying employment income for the qualifying year or £300,000, subject to transitional provisions. High earners with extensive overseas travel no longer receive unlimited relief.

That cap bites only after the taxpayer identifies qualifying foreign employment income and relevant deductions. A high share of overseas workdays does not necessarily translate into the same share of tax relief across total compensation. Payroll, bonuses and equity can all produce a different result.

Remittance Rules and Allowance Trade-Offs

The remittance position also changed after the rule reform. HMRC says relief is available whether the income is paid into a UK bank account or an overseas account, and income received offshore can be remitted to the UK without a charge. Older income needs closer handling.

Employment income linked to a pre-April 6, 2025 period that remains taxable on remittance may still need to be paid into a qualifying overseas bank account and kept offshore to benefit from older OWR treatment. That issue can surface in trailing bonuses, deferred pay and equity tied to duties performed before the new regime took effect.

Making an OWR election can also strip out other tax benefits. HMRC says an employee who elects for OWR loses the Personal Allowance for that tax year, the Capital Gains Tax Annual Exempt Amount for that tax year and the ability to claim foreign income or foreign capital losses in that year.

That trade-off means the relief does not suit every filer. A worker with modest foreign workday income may gain little after giving up those allowances. A higher earner may already have lost the Personal Allowance through tapering, but the rest of the calculation still matters.

Payroll, Bonuses and Equity Complications

Payroll records need to match the final claim. Some employers run PAYE on all earnings. Others adjust withholding during the year based on expected foreign workdays. The tax return should reconcile actual overseas duties with payslips, P60, P45 where relevant, assignment letters, bonus statements, equity award documents, shadow payroll calculations, employer workday reports and tax equalisation papers.

Bonuses and share-based pay often demand separate calculations. A cash bonus may cover a performance period spread across countries and tax years. Restricted stock units or options may have grant, vesting and exercise dates that cut across the employee’s move into the UK. HMRC’s guidance says OWR can cover employment-related securities income, so equity cannot be treated as an afterthought.

Common Mistakes and Practical Steps

Several recurring mistakes shape failed or weak claims. Employees often assume OWR covers anyone who travels for work. Some treat foreign clients as proof of overseas workdays, though the actual test is where the employee sat or stood while doing the work.

Others miss the filing step entirely. HMRC says the election belongs in the return for the qualifying year, and the amount must be stated there. Split-year errors, missing records and failure to apply the annual cap can all distort the figure before HMRC ever reviews it.

The practical file for 2026 usually starts with the arrival date, residence analysis and split-year status, then moves through the employment contract, assignment letter, payroll statements, bonuses, benefits, equity awards, travel records and the day-by-day work calendar. Notes on mixed days, travel days and remote-work days can matter later if the pattern is challenged.

Overseas Workday Relief remains valuable for mobile employees who arrive in the UK after a long period abroad and keep working across borders. The relief can run for as long as four tax years, but only if the employee qualifies, tracks each overseas day, makes the OWR election in Self Assessment and calculates the claim with the cap, split-year rules and lost allowances in view.
