If you’ve recently had the pleasure of recovering all the tax paid on your seafarers’ earnings through Cfarertax, you may have noticed a little extra in your bank account.

Not just the rebate you were expecting, but a bit more than that.

Most seafarers understand that they are entitled to reclaim the tax paid on their seafarers’ earnings, but many are unaware of the additional benefits.

When you successfully claim Seafarers’ Earnings Deduction (SED), you automatically free up your personal allowance, currently worth up to £12,570. This means that if you’ve paid tax on other income, such as occasional shore-based work, part-time employment, or interest earned on savings, you may also be able to recover that tax, provided your total income remains within your available personal allowance.

That’s why many Cfarertax clients ask, “Why is my refund more than I expected?”

 

And a Bit More Too…

If this is your first SED claim with HMRC, it’s common for your repayment to be delayed while additional checks are carried out.

While the downside is a longer wait for your refund, the upside is that HMRC will usually pay repayment interest on the outstanding amount, based on the length of the delay—and often at a surprisingly favourable rate.

So if your claim takes a little longer than expected, don’t worry. There may be a silver lining.

 

A More Secure Future…

If you’ve successfully claimed SED in previous years, it may be worth applying through Cfarertax to have your tax code adjusted.

As a recognised seafarer, you may qualify for a zero tax code, meaning no tax is deducted from your salary during the year. Instead of waiting until the end of the tax year to reclaim your tax, you receive the benefit immediately through higher monthly take-home pay.

Some seafarers prefer receiving a lump-sum refund at the end of the year. However, if circumstances change—such as spending too many days in the UK, taking extended leave, or having time off sick—you may fail to meet the qualifying conditions for SED and lose your entitlement to an annual repayment.

A zero tax code can provide greater security. As long as you remain with the same employer, the arrangement generally continues, allowing you to benefit from the tax relief throughout the year rather than waiting for a refund.

If you’re planning to stay with the same employer for several years and are already claiming SED, changing your tax code to zero could be the more secure and financially efficient option.
