Both returns, one engagement.
Your UK Self Assessment and your US federal return, prepared together and reconciled so treaty relief is claimed and nothing is taxed twice. One team, one scope, one deadline calendar.
Everything in the Dual Filing package
Who this package fits
A good fit if you…
- ✓Have to file in both the UK and the US for the same year
- ✓Want the two returns handled together, not by two firms
- ✓Have foreign income, and want treaty relief claimed properly
- ✓Prefer a fee agreed in writing before work starts
Probably not if you…
- ×Only need a UK return — see UK Self Assessment & MTD
- ×Are years behind on US filing — start with Streamlined Disclosure
- ×Only need US returns & FBAR/FATCA on their own
- ×Need business/corporate filing rather than a personal return
From quote to filed — four steps
Free consultation
We learn your income and filing history and give you a fixed quote before any work starts.
Share your documents
You send everything through one secure request — no duplicating it for two firms.
We prepare & reconcile
Both returns are prepared together, with treaty relief and credits applied so the two agree.
Review & file
You approve, we file both sides on time and hand over a combined deadline calendar.
The things clients ask first
How is this package priced?
As one fixed fee for the whole engagement, agreed in writing before any work begins. Never hourly. We do not publish a figure, because what the work involves depends on your income sources, your residence position and whether any years need catching up — two people filing in both countries can need very different work. The consultation and the quote are free.
Will this stop me being taxed twice?
That’s the aim. Foreign tax credits and the US–UK treaty are designed to prevent double taxation, and preparing both returns together is what lets us apply them consistently. We’ll confirm your position rather than assume it.
What if I’m behind on previous years?
Then this package may not be the right starting point — catching up usually runs through Streamlined Disclosure first. We’ll tell you honestly which route fits before you commit.
Is FBAR included?
Foreign account reporting is included where it’s required. If your situation adds anything unusual, we’ll flag it in the quote rather than as a surprise later.
