Student Loan Refunds: When You Have Overpaid and How to Claim It Back
The Student Loans Company holds money that belongs to people who do not know it is there. Some of it is sitting in accounts where the borrower earned under the threshold for the year but had deductions taken anyway. Some of it belongs to people whose employer put them on the wrong plan. Almost none of it comes back automatically.
Here are the five situations where a refund is due, the one that looks like an overpayment but is not, and how to actually get the money.
1. You Repaid Before You Were Due to Start
Repayments are not due until the April after you finish or leave your course. If deductions started earlier, usually because a new employer ticked the student loan box on your starter checklist before your first repayment date, every penny of that is refundable.
This is the most clear-cut of the five and it is common in graduate jobs that start in the September before your first April.
2. You Earned Under the Annual Threshold
Deductions are worked out per pay period, not across the year. If your earnings in a particular month go over the monthly threshold, your employer takes 9% of the excess in that month, even if your total for the year comes in below the annual threshold.
Where the year genuinely ends below the annual threshold for your plan, you can claim all of those deductions back.
Your total income for the year is £28,000, which is below the Plan 2 annual threshold of £29,385. So you repay nothing for the year, and that £319 is refundable.
Two conditions. The tax year has to have ended, and the SLC has to have confirmed your income with HMRC, which typically means waiting until well into the following tax year. And it does not happen on its own: you have to request it.
3. Your Employer Put You on the Wrong Plan
Plan types get miscoded regularly, usually from a starter checklist filled in from memory. Being placed on Plan 2 when you are actually on Plan 1, or on any plan at all when you have already cleared the loan, produces deductions that were never due.
Check your payslip against the plan you should be on. If it is wrong, tell payroll to correct it going forward and claim the difference from SLC for the period it was wrong.
4. You Repaid More Than You Owed
When your balance reaches zero, PAYE does not stop instantly. It takes around four weeks for the instruction to reach your employer, and deductions during that gap are money you did not owe.
The SLC will normally either contact you or refund this automatically, and it shows up in your bank account as an SLC receipt. It is still worth watching for, because "normally" is not "always". The best protection is to switch to a direct debit for your final year of repayments, which SLC offers precisely to stop this happening.
5. Voluntary Overpayments: Almost Never
If you have made voluntary extra payments to clear the loan faster, you cannot have them back. The only exception is where you have finished paying off the loan and repaid too much overall.
This is the one to think hardest about before acting. A voluntary repayment is irreversible, and if your circumstances change later, redundancy, a career break, reduced hours, that money is not available to you and the loan you were paying down would have quietly stopped costing you anything anyway.
The One That Looks Like an Overpayment and Is Not
Take the same bonus, but on a higher salary.
Total deducted across the year is roughly £408. Your income for the year is £34,000, so your actual liability is 9% of £4,615, which is £415.35. You have not overpaid at all. If anything you are slightly short.
The rule to take from this: a bonus feels like it triggers an unfair deduction, and it does distort a single month, but it only produces a refund if your income for the whole year lands below the annual threshold. Where annual income is above it, the employer deducted correctly and there is nothing to reclaim.
How to Claim
For the under-threshold refund, log in to your online repayment account with the SLC and make the request there. For everything else, contact the SLC directly.
Have ready:
- Your customer reference number, which is on any SLC letter or your online account
- The tax year or years you are claiming for
- Your P60s, or payslips showing the deductions
- Your National Insurance number
- Bank details for the repayment
Interest is payable on excess repayments, so a refund that takes months to process is not simply eroded by the delay.
How Far Back Can You Go?
This is worth being careful about, because a lot of websites state a firm limit and there is no such limit written into the regulations or the official guidance. Neither the SLC's published guidance nor the HMRC manual sets one out.
The practical advice is therefore to claim as soon as you spot it rather than to rely on a deadline that may or may not exist, and to keep P60s. If you are claiming for an older year, expect to have to evidence it yourself, because your employer's records and your own memory both get thinner with time.
If You Live Abroad
Overseas borrowers repay directly to the SLC rather than through PAYE, usually by direct debit at an amount set from the income evidence they have provided. Where you have been placed on the fixed monthly amount that applies when no income details are supplied, and your actual income was below the overseas threshold for your country, that is exactly the kind of overpayment worth querying, along with the income evidence to support it.
What to Check Each April
Make this a five-minute annual job when your P60 arrives:
- Look at the student loan figure on the P60 and check the plan type on your payslip is right.
- Compare your total pay for the year with the annual threshold for your plan.
- If deductions were taken and your income came in below the threshold, request the refund.
- Log in to your SLC account and check the balance is falling as you expect.
Use our student loan calculator to work out what your deduction should have been for the year, then compare it with what actually came out. The two matching is reassuring. The two not matching is worth a phone call.
