UK Payroll for Overseas Employees: 2026 Guide

Introduction: UK Payroll for Overseas Employees in 2026

Running UK payroll for overseas employees rarely stops simply because someone boards a plane. PAYE obligations usually continue, National Insurance follows its own separate timetable, and the host country often starts its own withholding at the same time. Consequently, employers frequently withhold in two places at once without realising it.

Furthermore, the rules changed materially in recent years. Section 690 moved to an annual notification process, overseas workday relief acquired new caps, and the UAE tightened its wage payment deadlines. This guide explains what UK employers must operate, when they can stop, and how the United States and the Emirates interact with the British payroll.

Why UK Payroll for Overseas Employees Usually Continues

PAYE attaches to the employment, not to the employee's postcode. Therefore, a UK employer with a UK contract generally keeps operating PAYE when staff work abroad, at least initially. HMRC's guidance for employers with internationally mobile staff sets out the framework: https://www.gov.uk/hmrc-internal-manuals/paye-manual/paye81513

The Residence Question Drives the Answer

An employee who remains UK tax resident stays taxable on worldwide employment income, so full PAYE continues. Meanwhile, an employee who becomes non-resident remains taxable only on earnings for UK duties. Accordingly, the payroll answer depends on a residence analysis performed before departure, not on an assumption made afterwards.

Section 690 Notifications Replaced Directions

Since 6 April 2025, employers notify HMRC online of the proportion of earnings subject to PAYE rather than waiting for a written direction. Additionally, the notification must be renewed for each tax year, and earlier directions ceased to apply. ICAEW summarises the change for practitioners: https://www.icaew.com/insights/tax-news/2025/apr-2025/new-process-and-rules-for-international-employees

Overseas Workday Relief and Its Cap

Overseas workday relief can exclude the non-UK duties element of pay for qualifying new arrivals. However, the relief now operates under a percentage cap, and the amount delivered through payroll is aligned to that limit from April 2026. Consequently, payroll teams should reconcile provisional relief against the year-end Self Assessment position rather than assuming they match.

National Insurance Runs on a Different Clock

National Insurance rarely stops when income tax does. Where the employer has a place of business in the UK, the employee was UK resident immediately before leaving, and the employee remains ordinarily resident here, Class 1 contributions continue for 52 weeks after departure. HMRC explains the position in leaflet NI38: https://www.gov.uk/government/publications/social-security-abroad-ni38/guidance-on-social-security-abroad-ni38

Reciprocal Agreements Prevent Double Contributions

Where the UK holds a social security agreement with the destination country, an employer can obtain a certificate confirming continued UK liability, and the host country then charges nothing. The United States is one such country. Therefore, a London employer posting staff to New York should secure coverage evidence before the first American payroll run.

The UAE Sits Outside That Protection

No comparable UK-UAE social security agreement covers private-sector expatriate staff. Nevertheless, the Emirates imposes no social insurance on non-GCC nationals, so the practical outcome is usually clean: UK Class 1 for 52 weeks, then nothing. Importantly, UAE and GCC nationals fall under separate pension arrangements administered locally.

Voluntary Contributions Protect the Record

Once compulsory liability ends, employees often want to preserve their state pension record. Additionally, voluntary Class 2 or Class 3 contributions may be available depending on circumstances, and the gov.uk guidance above covers eligibility. In our experience, staff value this far more than employers expect, and it costs little to arrange.

The United States Layer: Withholding, Totalisation and Form 673

American assignments create the densest overlap, because the United States taxes citizens wherever they live and operates its own federal withholding. As a result, a UK employer with American staff can face genuine dual withholding without careful sequencing.

Certificates of Coverage Under the Totalisation Agreement

The UK-US totalisation agreement prevents simultaneous social security contributions on both sides for posted workers. The Social Security Administration explains the agreement and the certificate process: https://www.ssa.gov/international/Agreement_Pamphlets/uk.html Consequently, obtaining the certificate early avoids a refund exercise that can take many months.

Form 673 and the Foreign Earned Income Exclusion

A US citizen working abroad for a US employer may reduce federal withholding by filing Form 673 with that employer, where exclusion tests are met. The IRS sets out the exclusion rules here: https://www.irs.gov/individuals/international-taxpayers/foreign-earned-income-exclusion Moreover, the underlying filing duty never disappears: https://www.irs.gov/individuals/international-taxpayers/us-citizens-and-resident-aliens-abroad

Watch the State-Level Trap

Federal treatment is only half the picture, because several states apply their own residency and withholding rules regardless of federal exclusions. Therefore, an employee retaining a home in a high-tax state can create an obligation that no treaty relieves. We flag this before the assignment letter is signed.

The UAE Layer: No Income Tax, Strict Wage Rules

Dubai charges no personal income tax, so there is no Emirati withholding to reconcile against PAYE. However, the UAE regulates how and when wages reach workers, and enforcement is administrative rather than fiscal.

The Wage Protection System

Employers with UAE-registered establishments must pay wages through the Wage Protection System administered by the Ministry of Human Resources and Emiratisation. Furthermore, the timing rules tightened during 2026, with wages due at the start of the following month and enforcement following quickly after any delay. MoHRE publishes the current requirements: https://www.mohre.gov.ae/en/home.aspx

End-of-Service Gratuity Replaces Pension Accrual

Expatriate staff accrue end-of-service gratuity based on final basic salary, broadly 21 days per year for the first five years and 30 days per year thereafter, capped at two years' wages. Additionally, an alternative savings scheme allows monthly contributions instead of a lump-sum accrual. Consequently, employers should recognise the liability in the accounts rather than discovering it at termination.

Permanent Establishment Risk From a Single Employee

One senior employee negotiating contracts in Dubai can create a permanent establishment for the UK company, bringing UAE corporate tax into play. The Federal Tax Authority sets out the corporate tax framework: https://tax.gov.ae/en/taxes/corporate.tax.aspx Therefore, payroll decisions and corporate tax exposure must be reviewed together, never separately.

A Practical Scenario

Consider an illustrative case of the kind we handle often. A Manchester engineering firm posts a project manager to Abu Dhabi for two years and a finance lead to Chicago for one. The Abu Dhabi employee stays on UK PAYE until a section 690 notification reduces it, pays UK Class 1 for 52 weeks, then stops, and accrues gratuity locally. Meanwhile, the Chicago employee obtains a certificate of coverage, files Form 673 with the payroll team, and triggers a state filing the firm had not budgeted for. Subsequently, both assignments run cleanly because the analysis preceded the first pay run.

How Tranzesta Can Help

Tranzesta operates the whole picture from one desk: UK PAYE and real-time information filings, section 690 notifications, NIC liability mapping, US totalisation certificates and Form 673 support, and UAE WPS-compliant payroll with gratuity accounting. Furthermore, we review permanent establishment risk alongside payroll, because the two questions arrive together.

Conclusion

UK payroll for overseas employees continues by default, ends only on evidence, and interacts with two separate clocks for tax and National Insurance. Section 690 notifications now require annual renewal, Class 1 contributions typically run for 52 weeks, and the destination country adds its own layer. Meanwhile, American assignments demand totalisation certificates and state-level care, and Emirati assignments demand WPS discipline and gratuity provisioning. Ultimately, employers who analyse residence and social security before departure avoid refunds, penalties, and unhappy staff. Speak to Tranzesta before your next international move.

Frequently Asked Questions

Do I still run UK payroll for overseas employees after they move abroad?

In most cases you continue operating PAYE, because the obligation attaches to the UK employment rather than the employee's location. However, you can reduce the amount subject to PAYE by submitting a section 690 notification to HMRC where the employee performs duties abroad.

How long do I pay UK National Insurance for an employee working abroad?

Class 1 contributions usually continue for 52 weeks after departure where the employer has a UK place of business and the employee was UK resident immediately beforehand. Additionally, a social security agreement with the host country may extend UK-only liability and prevent local contributions.

Does an employee in Dubai pay income tax on a UK salary?

The UAE imposes no personal income tax on employment income, so no Emirati withholding applies. Nevertheless, UK tax may still apply depending on residence status and where the duties are performed.

What is a certificate of coverage for a US assignment?

A certificate of coverage confirms which country's social security system applies under the UK-US totalisation agreement, preventing contributions in both. Therefore, employers should apply before the assignment begins rather than reclaiming afterwards.

Must a UK company use the UAE Wage Protection System?

A UK company with a registered establishment employing staff in the UAE must pay wages through the Wage Protection System, subject to defined exemptions. Furthermore, late payment triggers administrative sanctions quickly, so payment timing matters as much as amount.

Can an overseas employee create a taxable presence for my UK company?

A single employee concluding contracts abroad can create a permanent establishment, exposing the company to local corporate tax and filing duties. Consequently, we assess payroll and permanent establishment risk together before any posting is confirmed.
