UK Self Assessment for Non-Residents with UK Employment Income
Non-UK residents who receive UK employment income — whether from a UK employer, from employment income with a UK source, or from equity awards tied to UK work periods — must report this income through UK Self Assessment in most cases. The tax position is complex: UK and foreign workday splits, Overseas Workday Relief (for eligible short-term business visitors), and double taxation treaty provisions all affect the amount of UK tax owed. We handle this specialist area for non-residents with UK work obligations.

Frequently asked questions about UK Self Assessment for Non-Residents with UK Employment Income
I work for a UK company but live overseas — am I taxed in both countries?
Most likely yes, but a double taxation agreement may provide relief. UK tax applies to the portion of your employment income attributable to UK workdays. Your country of residence may tax all of your income, but you would claim a tax credit for UK taxes paid. The exact position depends on the specific treaty.
What is Overseas Workday Relief?
Overseas Workday Relief (OWR) allows eligible non-domiciled non-residents to exclude from UK tax the portion of their employment income earned on overseas workdays — provided that income is paid into and kept in an overseas bank account. OWR is available for up to three years after arriving in the UK as a non-dom.
I received a share award that vested after I left the UK — is any of it UK-taxable?
The UK taxes the portion of the share award that corresponds to UK workdays during the vesting period. If your vesting period was three years and one of those years included UK employment, roughly one-third of the gain may be UK-taxable. The calculation requires the vesting period, UK workdays, and total workdays.
My UK employer deducted full PAYE — can I get a refund for overseas workdays?
Yes. This is one of the most common situations we handle. UK PAYE is often deducted on full salary without adjusting for overseas workdays. A Self Assessment return allows you to apportion the income correctly and claim a refund of any overpaid PAYE.
