One Team for Your US & UK Taxes
Coordinated tax preparation and planning for individuals and businesses with obligations on both sides of the Atlantic.
We prepare US and UK taxes for people and businesses whose lives and money cross the Atlantic. One team files in both countries and claims treaty relief correctly, so you are not taxed twice.
"Cross-border tax goes wrong when each country's adviser sees only half the picture. Our answer: one team prepares both returns and builds a single plan."

Real Outcomes From One Strategy
Across Two Tax Systems
Streamlined Catch-Up, Zero Penalties
An American in London, 9 years behind on US filings, entered the Streamlined Foreign Offshore Procedures and came out fully compliant, with no penalties and no US tax owed after foreign tax credits.
PFIC Rescue & Restructuring
A dual citizen held six figures in UK funds inside an ISA. We quantified the PFIC exposure, filed the required Forms 8621, and rebuilt the portfolio around US-friendly holdings.
UK Expansion Done Right
A US SaaS company opening in London needed VAT registration, PAYE, and a transfer pricing position. One engagement covered both sides, with no surprises at year end.
One Firm.
Both Jurisdictions.
We are specialist advisers for the US/UK tax corridor. US CPAs and UK tax advisers work the same file, so relief goes to the right country, elections happen at the right time, and nothing falls into the gap between two separate preparers. Fees are fixed, quoted up front, and cover both returns.
