How Seafarers' Earnings Deduction works

To get the deduction you must:

• work on a ship - oilrigs and other offshore installations aren't ships for the purposes of Seafarers' Earnings Deduction - but cargo vessels, tankers, cruise liners and passenger vessels are
• work all or part of the time outside the UK - this means that for each employment you must carry out duties on at least one voyage that begins or ends at a foreign port
• be 'ordinarily resident' in the UK - or resident for tax purposes in a European Economic Area (EEA) State (other than the UK) - find out more by following the link below

You get the deduction from your earnings as a seafarer if you have an 'eligible period' of at least 365 days that consists mainly of days when you are absent from the UK. There are special rules for working this out - see the section below 'How to calculate the deduction'.

Who can get the deduction

Anyone who works on a ship can get the deduction. For example, you can get it if you are employed as an entertainer, cook, travel courier or musician.

You can't get the deduction if:

• you are a Crown employee - so Royal Navy sailors can't get it
• you're not ordinarily UK resident nor a resident of an EEA State (other then the UK) but there may be other tax reliefs you can claim – see the section ‘If you’re a non UK resident seafarer’ below

How to calculate the deduction

To see if you're entitled to the deduction, you need to work out whether your days outside the UK are enough to make up an eligible period. You can use Help Sheet HS205 'Seafarers' Earnings Deduction' to help you do this.

If you have more than one job

If you've got more than one job, you'll still get the deduction against your pay as a seafarer if you meet all the conditions.

Records you'll need to keep

HM Revenue & Customs (HMRC) may want to check your tax return so you'll need to keep details of:

• completed Help Sheet HS205
• air tickets or other travel vouchers
• hotel bills or other receipts
• passports and visas
• seafarer's discharge book
• freeboard logs of the ships you carried out duties on

If there's any doubt they will contact your employer for details of the ship's voyage and crew.
