You may also need to file FBAR and FATCA reports for foreign financial accounts. We handle both US and UK filings to ensure you remain compliant.
US tax returns are typically due April 15, with automatic extensions to June 15 for expats. UK self-assessment deadlines are October 31 for paper returns and January 31 for online filing. We manage all deadlines and ensure timely filings for both jurisdictions.
