Seatax

Established over four decades ago, Seatax has become the UK's leading specialist in tax advisory services for seafarers and yacht crews. Our expertise stems from decades of focused experience in maritime tax legislation, including the Seafarers Earnings Deduction (SED) and Self Assessment requirements. We provide comprehensive tax return preparation, compliance services, and strategic advice tailored to the unique circumstances of maritime professionals. Our team specialises in navigating complex tax treaties, double taxation agreements, and offshore installation regulations. With a proven track record of handling HMRC investigations and backdated claims, we ensure clients maintain full compliance while maximising legitimate tax allowances.

Our service includes document verification, midnight position sheet analysis, and voyage record management to meet HMRC audit requirements. We serve both UK-based and internationally employed seafarers, offering a streamlined process for tax registration, return submission, and ongoing compliance. Our fee structure remains transparent and competitive, with standardised pricing for core services. As a registered Data Controller, we maintain strict confidentiality while providing accessible support through multiple communication channels. Our commitment to continuous service improvement has made us the trusted choice for maritime tax compliance since the 1977 Finance Act introduced current seafarer tax regulations.
