Overpay or Invest

Student loan repayments if you're self-employed

. Figures are for 2026–27 and are compared with GOV.UK every month. How we check.

If you’re employed, your student loan is taken from your pay automatically. If you’re self-employed, or complete a Self Assessment tax return for another reason, it works differently, and the first return after you start earning above the threshold can come as a shock.

It goes through Self Assessment

HM Revenue and Customs (HMRC) works out how much you repay each year from your Self Assessment tax return, based on your income for the whole year. You pay at the same time as you pay your tax. There’s no separate bill from the Student Loans Company for that portion.

The calculation is the one you already know: your plan’s rate on income above your plan’s yearly threshold. See how much will I repay? for the formula and current figures.

If you’re also employed

If you earn over the minimum amount, your employer will deduct repayments from your salary as normal. On your tax return, HMRC then looks at your combined income for the whole year.

GOV.UK’s example: someone on Plan 1 with £32,000 self-employment income and a £10,000 job has combined income of £42,000. That’s over the Plan 1 threshold, so the repayment is worked out on the amount above the threshold. Repayments already taken from the salary are deducted from what’s owed.

Check your payslips or P60 to see how much you’ve already repaid during the tax year. You’ll need that when you fill in your return. The tax year runs from 6 April to 5 April.

What else counts

GOV.UK also says that if you get pension income, HMRC uses your total annual income, including workplace, private and State Pension. See student loan repayments and pension income. For other kinds of income on your return, check HMRC’s guidance for your situation.

Making it manageable

Should you overpay while self-employed?

Income that varies year to year makes it harder to know whether you’ll repay in full, which decides whether overpaying helps. See should I overpay my student loan? and consider keeping a cash buffer for lean months, since extra repayments can’t be refunded.
