If you are UK resident and work on a yacht or superyacht, your earnings are taxable in the UK — even when you are paid in euros or dollars, offshore, by a foreign employer. Most professional yacht crew, though, can claim Seafarers’ Earnings Deduction and reduce the income tax on those earnings to nil. Specialist tax advice for yacht and superyacht crew is the corner of seafarers’ tax Seatax has worked in for over 40 years.
Do yacht crew pay UK tax?
It comes down to your tax residency status. If you are resident in the UK for tax purposes, you are taxed on your worldwide income — and that includes wages paid by a foreign owner or management company into a foreign bank account. Most crew who keep a home base in the UK remain UK tax residents while working at sea. Being paid offshore, in another currency, by an employer with no UK office does not take the income outside UK tax.
What changes the outcome is Seafarers’ Earnings Deduction. It is a 100% deduction against your earnings as a seafarer — a tax relief specific to working seafarers — so where it applies in full, the income tax on those earnings is nil, effectively making them tax free for income tax purposes. Yacht crew are seafarers for this purpose: HMRC’s test is that you perform your duties on a ship, and it says nothing about the size of the vessel or whether it carries guests or cargo.
Deck, interior, engineering, galley — the department doesn’t matter
HMRC’s test is that you perform all of your duties on a ship, or most of them with the rest being incidental. Whether you are working on a superyacht, a charter yacht or a private sailing yacht, a deckhand, a chief stewardess, a chef, an engineer and a captain are all seafarers for this purpose if they are employed to work on the vessel.
Employed, not self-employed. SED is a deduction from employment income. Crew engaged through their own company or on a genuinely self-employed basis are in a different position — it is worth checking how your contract actually describes you before assuming either way.
The conditions you have to meet
| Condition | What it means on a yacht contract |
|---|---|
| Eligible period of at least 365 days | Not a single contract — a continuous period made up of days abroad and qualifying visits home. It can span seasons and boats. |
| No visit to the UK over 183 consecutive days | Long leave between seasons is where yacht crew most often break their period. |
| UK days no more than half the total | Tested at the end of each return visit, not just once a year. |
| Voyages that begin or end outside the UK | Mediterranean and Caribbean seasons qualify easily. UK-based day work and refit periods alongside in a UK yard need care. |
You are outside the UK on a given day if you are outside the UK at midnight at the end of it. Keep that in mind for UK deliveries, Solent-based work and refits — a vessel alongside in a UK yard at midnight is a UK day.
What to keep
HMRC does not want documents sent with the return, but it can ask for them later, and a claim you cannot evidence is a claim you lose. Keep your discharge book or sea service testimonials, your contracts, itineraries and log extracts showing ports, flight bookings and boarding passes, and your payslips.
What Seatax does for yacht crew
This is specialist work — a general accountant sees a handful of seafarer returns a year; it is all we do. On enrolment with Seatax, you authorise us to act on your behalf with regard to all income tax matters. That authority is sent to the appropriate section at HM Revenue & Customs, and from then on your correspondence with HMRC is directed through Seatax. We complete your Self Assessment, make the SED claim, and if your return is picked out for an investigation during your period of enrolment, we deal with it for you.
For all new clients we can, if required, check back up to four complete income tax years — if you have been at sea and never claimed, or claimed incorrectly, backdating a claim may recover tax you have already paid.
National Insurance is separate
SED reduces income tax only. National Insurance follows its own rules, which depend on where you live, where your contract was made and where your employer is based — and for yacht crew on foreign-flagged vessels the position varies more than most. More on National Insurance for seafarers.
Wherever your boat is, we can act for you
Seatax has worked for seafarers for over 40 years from Doncaster, by post, phone and email — our clients are at sea, in the Med, in the Caribbean and across the UK, not in our waiting room. Distance has never been part of the job.
Common questions
I’m paid in euros into a foreign account. Do I still need to file in the UK?
Yes, if you are UK resident — your tax obligations don’t disappear because the payroll is offshore. You still need to file a tax return: SED has to be claimed on your Self Assessment; it is not applied automatically.
Do I need to be on the same yacht for 365 days?
No. You need an eligible period of at least 365 days, but it can span several contracts, different vessels and the leave between them, provided the day-count rules are met throughout.
I’ve been at sea for years and never claimed. Is it too late?
Not necessarily. Claims can be backdated within HMRC’s time limits, and for new clients we can check back up to four complete tax years. See backdating a SED claim.
Does dual-season work (Med summer, Caribbean winter) help my claim?
Usually, yes — voyages beginning and ending outside the UK are exactly what the rules reward. The risk point is long UK leave between seasons, which can break your eligible period.
Not sure where you stand?
Tell us your vessel, your dates and where you sailed. We will tell you plainly whether you have a claim.
