UK resident seafarers are taxable on worldwide income, even if they are paid gross or by a foreign company. If you qualify for Seafarers’ Earnings Deduction you may pay no UK income tax on eligible seafarer earnings, but you still need to file a Self Assessment return.

SED is UK tax relief that can give a 100% deduction against eligible employment income for seafarers who work on a ship, are UK resident, and meet the qualifying period (usually 365 days with the half-day rule and a foreign-port voyage).

Yes, if you are UK resident and paid gross. Yacht captains, officers, deckhands and interior crew can still be caught by UK tax and by double tax agreements. We specialise in bringing yacht personnel back into the UK system cleanly.

Offshore installations used in oil and gas are not ships for SED. Fixed and floating production platforms, FPSOs, FSUs and MODUs generally do not qualify. If you work in the North Sea on a qualifying ship you must keep midnight position sheets showing whether the vessel is inside or outside 12 nautical miles.

Keep a computation of dates, air tickets, hotel bills, passports and visas, your discharge book or a letter from the Captain or company, and for North Sea duties the midnight position sheet. HMRC may contact your employer to confirm voyages.
