Living in the UK while working for an overseas employer

An overseas employer does not make you self-employed

If you live and perform your duties in the UK, a foreign contract and payment into an overseas account do not by themselves establish the tax treatment. Start with the actual relationship: who controls the work, carries risk, provides equipment and sets terms. HMRC’s CEST tool ↗ helps assess status for tax; a contract label does not settle every employment-law question.

Do not register as a sole trader simply because the company lacks a UK office. Obtain the employer’s written position and advice from someone experienced in cross-border payroll.

Assemble the facts for both countries

Collect the contract, payslips, moving dates, a country-by-country workday calendar, nationality, immigration conditions and evidence of overseas deductions. Record whether the company has a UK establishment or another legal employer is involved.

Tax residence ↗ affects overseas-income taxation, but nationality, a bank account or a standalone “183-day rule” does not replace the full analysis. Working from a UK home requires consideration even when the salary payer is abroad.

Establish how payments will be reported

Ask who must operate UK PAYE, which National Insurance rules apply and whether another country’s social-security certificate is relevant. DPNI allows direct employee payments of PAYE and contributions in specified cases ↗. It is a particular procedure, not a universal alternative for every overseas employer.

A personal Self Assessment return does not automatically discharge monthly payroll duties. Agree registrations and payment arrangements before work starts; if salary has already been received, list the affected periods and ask how to correct matters.

Double taxation and employment terms

Keep proof of foreign tax. Relief depends on the income and applicable treaty; overseas withholding does not automatically remove UK reporting obligations.

Clarify holiday, sick pay, pensions, currency, fees, equipment and permission to work from the UK. Ask your adviser for separate conclusions on Income Tax, contributions and employment conditions, with actions for each party and ongoing costs. Do not relabel employment as fictitious freelancing merely to simplify transfers.
