Accountants in London
Specialist US & UK cross-border tax accountants based in Soho, Central London. We help American expats, dual filers, and creative businesses stay compliant with both the IRS and HMRC.
Jungle Tax is a London-based firm of US and UK cross-border tax accountants headquartered in Soho. We serve American expats, UK residents with US income, dual citizens, founders, and creative businesses who need one team fluent in both IRS and HMRC rules, available in person or fully remote.
Why choose a London firm for US & UK tax?
London is home to one of the world's largest communities of Americans abroad, alongside UK residents holding US green cards, shares in US companies, or income from the United States. That combination creates a tax problem most high-street accountants are not equipped to solve: you are simultaneously accountable to HMRC and the IRS, and the two systems rarely line up.
Because the United States taxes its citizens on worldwide income regardless of where they live, an American in London must file a US federal return every year on top of UK Self Assessment. Get the coordination wrong and you can lose foreign tax credits, misreport pensions and ISAs, or trigger PFIC problems on ordinary UK funds. Our team works both returns together so relief flows correctly and the same income is never taxed twice.
What our London accountants do
US tax returns & IRS filing
Federal and state returns for US citizens and green card holders in London, including FBAR and FATCA reporting.
UK Self Assessment
HMRC Self Assessment, PAYE reconciliations, capital gains and rental income for UK residents and non-doms.
Cross-border tax planning
Treaty positions, foreign tax credits, residency and domicile planning across the US and UK.
IRS streamlined filing
Catch-up filings for Americans who have fallen behind on US returns while living in the UK, penalty-free where eligible.

Accounts and tax for founders, freelancers, influencers and agencies operating between London and the US.

In person in Soho, or fully remote
Our HQ sits at Waverley House, 9 Noel St, in the heart of Soho, a short walk from Oxford Circus, Tottenham Court Road and Piccadilly Circus. Clients who prefer a face-to-face meeting can book an appointment to review their US and UK position with an adviser in person.
Equally, everything we do works remotely. Secure document upload, encrypted portals, video consultations and e-signature mean you never have to visit the office if you would rather not. Whether you are in Central London, commuting from the Home Counties, or filing from overseas, you get the same senior cross-border expertise either way.
Areas we serve
From our Soho base we support clients across Central London and Greater London, and remotely throughout the UK, the United States, and beyond. Common areas we work with include:
