Two tax authorities, one company. We keep both returns straight.
If your company touches both the UK and the US, you have two corporate tax systems watching — each with its own rules, rates and deadlines. We prepare both sides and make sure they agree, so relief isn’t lost and nothing is taxed twice.
Two systems that don’t speak the same language
UK corporation tax and US federal and state tax calculate profit differently, run on different years, and grant relief in different ways. Handled separately, the two returns drift apart — foreign tax credits get missed, positions contradict each other, and you overpay. We prepare them as one coordinated job.
Both returns, reconciled
Three steps, one team
Map the group
We set out which entity is taxed where, on what, and how profit and tax flow between them.
Prepare both computations
We calculate each side on its own rules, then reconcile so the positions are consistent and no relief is stranded.
File & track deadlines
We file in both jurisdictions and manage the combined calendar so nothing slips between the two.
The things clients ask first
Will my company be taxed twice?
Usually not, if it’s handled properly. Foreign tax credits and the US–UK treaty are designed to prevent double taxation — but only if the returns are prepared together and the claims are made correctly.
The UK and US use different year-ends — is that a problem?
It’s a common one. We reconcile the periods so profit and tax line up across the two filings rather than being reported on mismatched bases.
Do you handle US state tax as well as federal?
Where it’s relevant, yes — state nexus and filing can apply separately from federal. We’ll confirm which states you actually have obligations in rather than filing everywhere by default.
Let’s get both returns telling the same story.
A free consultation, no obligation. Tell us about your group and we’ll map both sides — with a fixed price before any work begins.
