UK Self Assessment
HMRC returns prepared alongside your US filing, so residence, remittance and relief are decided once rather than twice.
UK Self Assessment, coordinated with your US return.
HMRC's return looks simpler than the IRS's, but the cross-border questions — residence status, foreign income, what the US has already taxed — are where refunds get missed and enquiries start.
We prepare both returns as a single position so relief is claimed in the country the treaty says has to give way.
What we do
01
Self Assessment preparation
The full return including foreign pages, with income reported consistently across both jurisdictions.
02
Residence and split-year
Statutory Residence Test analysis, split-year treatment and the evidence to support the position taken.
03
Foreign tax credit relief
Relief claimed in the right country and the right order, so the same income is not taxed twice.
04
Disclosure and enquiries
Voluntary disclosures and correspondence with HMRC where earlier years need correcting.
Why us
One position, two authorities
Filing each return separately is how people end up paying twice or claiming relief that unravels under scrutiny.
We reconcile the two before either is submitted, and keep the working so a later enquiry has an answer ready.
When it comes to questions that cross two tax systems, you need specialists who work in both every day. Meet the team that make it happen.
View our peopleFrequently asked
Do I need to file in the UK if I already file in the US?
Almost certainly, if you are UK resident or have UK source income. The two systems are independent; filing in one does not discharge the other.
Do I need to file if I have left the UK?
If you keep UK-source income such as rent, or meet the Statutory Residence Test for part of the year, yes. Leaving does not close the record by itself.
What are the deadlines and penalties?
Online filing is due 31 January following the tax year end, with an automatic penalty for lateness and further charges as it continues. Payment is due on the same date.
How do I claim credit for US tax paid?
Through the foreign tax credit relief pages, which need the US position finalised first. This is the main reason we prepare both returns together.
Does the remittance basis apply to me?
It depends on your residence and domicile position, and the regime has changed. We will tell you plainly whether it is available and whether it is actually worth claiming.
