Do seafarers repay student loans?
Student loan repayments follow taxable income, not the number on your wage slip. If SED reduces qualifying seafarer employment income to nil and you have no other taxable income, there is typically nothing to repay on that income for the year. The loan is not written off.
Pain
Student Loans Company still wants repayments on gross sea pay. SED may have already taken that income out of tax.
Solution
We file the return so taxable income is right, then you can deal with SLC on the back of a correct HMRC figure.

SED does not cancel the loan
Interest can still accrue. If you later work ashore above the threshold, PAYE deductions restart. Other income — rent, UK shore jobs, self-employment — can still trigger repayments.
What to tell SLC
Be careful with ‘foreign income’ questions. Qualifying SED earnings are not taxed as ordinary foreign income in the way SLC sometimes assumes. Wrong answers can switch collections back on.
Self-employed or agency arrangements that fail the employee-on-a-ship test will not get SED, so student loans run as normal.

Questions people ask
If I qualify for SED do I pay student loans?
Usually not on the SED employment income for that year if taxable income is nil. You may still repay on other income.
