UK Self Assessment

1. Overview

2. Seamless UK Self Assessment, coordinated with your French return

Peter JOHNSON SARL prepares your French Tax Declaration while our UK partner, Mandy Rees — an HMRC-registered Tax Agent — files your UK Self Assessment electronically via HMRC Gateway.

3. General rule

A UK non-resident must file a Self Assessment tax return if they have UK-source income that is taxable in the UK. This applies even if they are non-resident and not otherwise liable to UK tax, particularly where income is not fully dealt with through tax deducted at source.

4. Common situations requiring a return

Even if rent is paid net under the Non-Resident Landlord Scheme, HMRC requires a return to confirm the final liability. If you carry on a trade, profession, or vocation in the UK. For example, directors’ fees or where PAYE has not dealt with the full liability.

5. Our partnership with Mandy Rees
