Your UK tax, handled properly as a US citizen

Living in the UK as a US citizen means answering to two tax authorities. We take care of the UK side expertly, with the treaty and foreign tax credit position set up correctly so it works alongside your US return.

Whether you live on Merseyside or elsewhere in the UK, we prepare and file your UK self-assessment, leaving the US return with the preparer you already use.

FAQ

Common questions

Do I still have to file a US return while living in the UK?
Yes. The US taxes on citizenship rather than residence, so you continue to have US filing obligations while living in the UK, alongside your UK self-assessment.
Do you prepare my US return as well?
No. We are UK specialists and we handle the UK side only. You keep your own US preparer, and we make sure the UK position we file is clear and correct so it is straightforward for them to work from.
Will I end up paying tax twice?
Generally no. The US-UK treaty and foreign tax credits are designed to prevent it. Getting the UK side right, with the treaty position and credits properly claimed, is a large part of making sure that works as intended.
How do UK inheritance tax and US estate tax interact?
They are separate regimes with different thresholds and rules, and they can both bite on the same estate. We plan across both jurisdictions rather than treating them in isolation.
