Seafarers Earnings Deduction: tax relief if you work on a ship
If you're an employee working at sea outside of the UK check if you can claim tax relief on your earnings.
If you’re an employee and work at sea, you may be able to reduce your tax bill by getting the Seafarers’ Earnings Deduction.
To get the deduction you must have:
- worked on a ship
- worked outside of the UK long enough to qualify for the deduction - usually a minimum of 365 days
- been resident in the UK or resident for tax purposes in a European Economic Area (EEA) State (other than the UK)
You can’t get the deduction if you were:
- a Crown employee (for example, a Royal Navy sailor)
- not a UK resident
- not a resident of an EEA State (other than the UK)
If you had more than one job you’ll still get the deduction against your seafarer pay if you meet all the conditions.
Royal Fleet Auxiliary employees are eligible for this deduction if they meet all the conditions.
Records you’ll need to keep
HM Revenue and Customs (HMRC) may want to check your claim, so you must keep details including:
- a completed working 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
HMRC may contact your employer to confirm details of your ship’s voyage and crew.
How to claim Seafarers’ Earnings Deduction
To get the deduction from your seafarer earnings you must have an eligible period of at least 365 days that’s mainly made up of days when you were absent from the UK.
To see if you’re entitled to the deduction, work out if your days outside the UK were enough to make up an eligible period.
Use working sheet HS205 Seafarers’ Earnings Deduction to help you do this.
If you were resident in the UK
You’ll need to register for Self Asessment and fill in a tax return and relevant pages giving details of your income for the tax year you are claiming the deduction for.
If you weren’t resident in the UK but were resident in an EEA State
From the 2011 to 2012 tax year, you can claim the deduction using form R43M(SED) - Repayment Claim - EEA resident merchant seafarer.
Request an NT tax code
It may be possible for you to ask your employer to pay your wages without deducting tax, they would do this by operating a tax code called NT.
To qualify for this code you must:
- be resident in the UK
- be in a Pay As You Earn (PAYE) employment
- be a seafarer working onboard a vessel accepted as a ship for Seafarers’ Earnings Deduction purposes
- fill in a Self Assessment tax return each year
- have a contract of employment of at least 12 months
If you don’t have a 12 month contract, you must have been in continuous employment with the same employer for at least 6 months, working outside the UK.
If the employment against which you wish to claim code NT ceases or changes so that you no longer qualify you’ll need to tell HMRC immediately.
If it later transpires that you were not entitled to the code NT then you’ll be asked to repay any tax underpaid in one lump sum.
HMRC won’t issue an NT code until after they’ve processed your first claim to Seafarers’ Earnings Deduction.
This claim can be made either 12 months from the start of your seafaring employment or the start of the tax year previous to the year of claim – whichever is the later.
You can use form R44 to request the issue of tax code NT.
