WHO WE HELP

REMOTE WORKERS, LANDLORDS, RETIREES

We specialise in UK tax advice for individuals living overseas who still have UK income, assets, or business interests.

Working for a UK employer overseas?

If you're employed by a UK company but live overseas, your tax residency status is key. You may still be subject to UK income tax depending on how much time you spend in the UK and where your work is performed. Meanwhile, your employer might continue to deduct PAYE and National Insurance unnecessarily.

TIMELINE

LEAVING THE UK MILESTONES

Use this timeline to plan your departure from the UK tax system and stay fully compliant with HMRC.

Review tax position as a non-resident

If you continue to receive income from the UK (rental, pensions, dividends), you may still have UK tax obligations. Each type of income is treated differently for non-residents, so it’s essential to get tailored advice.

Be mindful of the temporary non-resident rules

The temporary non-resident rules can bring incomes and gains that are tax free in real time due to your non-resident status, back within the scope of UK taxation broadly if you return to the UK within five years. It is critical you take steps to avoid being caught by these rules upon repatriation to the UK.

Understand the Statutory Residence Test (SRT)

The SRT looks at the number of days you spend in the UK, as well as ties such as family, property, and work. Providing that you achieve a non-resident status, HMRCs right to tax your income will be limited to UK sourced income only and thus, it is critical that you understand the steps you need to take to achieve a non-resident status if you wish to minimise UK tax exposure whilst overseas.

Consider double taxation agreements

The UK has tax treaties with many countries to prevent you from being taxed twice on the same income. Applying these treaties can reduce your overall tax burden and avoid complications in your new country.

Inform HMRC you are leaving

To notify HMRC of your departure, you can complete Form P85 or SA109 pages on your self assessment tax return. This will trigger refunds or NT (No Tax) coding for employees.
