Student Loan Arrears and How to Reduce Your Repayments in 2026
Most people who search this topic are looking at a number on their SLC account that does not make sense, or they are getting a bigger deduction from their payslip than they expected, or they just got a letter about a balance that has been quietly building for months. That is a stressful place to be.
The good news is that there are legitimate ways to lower what you pay each month, and if you have arrears, there are clear steps to fix them. This guide covers all of it: what arrears are, why they build up, what the 2026 thresholds actually mean for your wallet, and how pension contributions, salary arrangements, and your employment setup can all affect your monthly deduction.
Use our student loan repayment calculator to get a real figure based on your income and plan type before you read any further. Knowing your actual number changes everything.
What "Student Loan Arrears" Actually Means
Arrears and your total loan balance are two different things. Most borrowers mix them up, and it causes real problems when they try to sort out their accounts.
Your total balance is the full amount you still owe, including interest.
Your arrears balance is the specific amount of payments you missed or failed to make when they were due. Arrears are overdue. Your balance is not all overdue, just the arrears portion.
Why does that distinction matter? Because the two are handled completely separately. If you return to the UK after living abroad and go back into PAYE employment, your payslip deductions do not touch your arrears. They only reduce your main balance. The arrears still sit there, unpaid, and SLC still expects you to deal with them separately.
The first step to clearing your debt is to learn exactly how to check your student loan balance so you know what is owed.
How Arrears Build Up on Your Account
Arrears do not usually appear out of nowhere. There are a few specific situations where they accumulate:
- You moved overseas and did not tell the Student Loans Company. In that case, SLC applies a fixed monthly repayment, which can reach up to £618.80 per month, and every month you miss it adds to your arrears balance.
- You were required to make direct repayments (for example, as a self-employed borrower) and missed payments.
- You submitted your annual overseas income assessment late or not at all, so SLC could not calculate your correct repayment amount and applied a default rate instead.
- You are on a repayment schedule and simply could not afford to keep up with it.
Each of these creates arrears in a different way, and the resolution process is slightly different for each one. Understanding which situation applies to you is the first step. Arrears often happen to expats who forget to update their employment details; check our guide on overseas student loan repayment to fix this.
What Happens When You Have Arrears
SLC has a Debt Fairness Charter, which means they are not supposed to chase you in ways that make your situation worse. In practice, though, leaving arrears unresolved does have consequences:
- Interest continues to add to your balance during the arrears period.
- SLC can pass the debt to a third-party collection agency.
- In more serious cases, they can apply for a County Court Judgement (CCJ), which affects your credit file and can make it harder to get a mortgage, a credit card, or some types of rental agreements.
- Overseas borrowers face increasing enforcement from 2026, including credit bureau reporting and a significant rise in legal cases.
None of that is inevitable. Most of it is avoidable if you contact SLC before things escalate.
For salaried workers, arrears are rare unless there is an administrative error in your employee student loan repayment setup.
How Can You Reduce Your Student Loan Payments?
This is the most practical part of the article. There are legal, legitimate ways to reduce your monthly student loan deduction. None of them involves dodging the system. They work within it, using rules that already exist but that most borrowers never hear about.
1. Salary Sacrifice Pension Contributions
This is the most consistently misunderstood area of student loan repayments. Standard pension contributions through your workplace, where you contribute from your gross pay and the provider claims tax relief, do not reduce your student loan deduction. Your PAYE deduction is based on your NICable income, which is your earnings before income tax but not before pension contributions made this way.
Salary sacrifice is different. With salary sacrifice, you agree to a lower contractual salary, and your employer pays the difference directly into your pension. Because your NICable income is now genuinely lower, your student loan deduction is calculated on the reduced figure.
Practical example: You earn £36,000 on Plan 2. Without salary sacrifice, your annual deduction is £585 (9% of £36,000 minus £29,385). If you sacrifice £3,000 into your pension, your effective NICable income drops to £33,000. Your deduction becomes £324. That is £261 less per year, just by using an arrangement your employer may already offer.
2. Multiple Employers and Threshold Splitting
If you work for two completely unrelated employers at the same time, each employer calculates your student loan deduction separately. They do not combine your salaries.
Say you earn £15,000 from one job and £13,000 from another on Plan 1 (threshold £26,900). Neither employer deducts anything because neither salary alone exceeds the threshold. Your combined income is £28,000, which is above the threshold, but your PAYE deductions come out as zero.
This does get caught at Self Assessment, so it is not a way to permanently avoid repayments. But it does affect your monthly cash flow, and understanding it helps you plan. For more details, read our employee student loan repayment guide.
3. Repayment Deferment While Earning Below the Threshold
This applies more to overseas borrowers or those in very low-paid work. You can formally request a repayment assessment based on your actual income. This is not deferral in the traditional sense.
It is the income-contingent system working as designed. Your rights and responsibilities include the right to pay zero when you genuinely earn below the threshold, and SLC is required to reflect that in your account.
4. Pension Contributions if You Are Self-Employed
If you complete a Self Assessment tax return, the rules are different and actually more generous. Personal pension contributions, including the basic rate tax relief added by the provider, are deducted from your total income before the student loan repayment is calculated.
So if you earn £35,000 and contribute £4,000 net into a personal pension, the provider tops that up to £5,000 (with 20% tax relief). Your income for student loan purposes becomes £30,000, not £35,000. On Plan 1, that calculation drops your repayment from around £1,168 to £718. That is £450 less, and it is not a loophole. It is how the regulations are written.
5. If Your Income Falls Below the Threshold
Repayments stop automatically through PAYE when your income drops below the threshold for your plan. You do not need to apply for anything.
If your income falls partway through the tax year, you may have overpaid earlier in the year. You can claim a refund after the tax year ends, but only if your total annual income was below your plan’s annual threshold. It does not apply if you just had a few low-earning months but ended up above the threshold for the year overall.
2026 Repayment Thresholds: What You Actually Pay
Your repayment threshold is the annual income level above which your deductions start. Below it, you pay nothing. Above it, you pay a percentage of the difference between your income and the threshold. That percentage is 9% for Plans 1, 2, 4, and 5, and 6% for the Postgraduate Loan (Plan 3).
Here are the confirmed thresholds for the 2026/27 tax year:
Loan Plan | Target Group | Annual Threshold | Monthly Threshold | Weekly Threshold | Repayment Rate |
Plan 1 | England or Wales loans before Sept 2012; all Northern Ireland loans | £26,900 | £2,241 | £517 | 9% |
Plan 2 | England or Wales loans between Sept 2012 and July 2023 | £29,385 | £2,448 | £565 | 9% |
Plan 3 | Postgraduate Master’s and doctoral loans in England or Wales | £21,000 | £1,750 | £403 | 6% |
Plan 4 | All Scottish borrowers | £31,395 | £2,616 | £603 | 9% |
Plan 5 | England courses starting after August 2023 | £25,000 | £2,083 | £480 | 9% |
Plan 5 repayments started for the first time in April 2026. If you started a UK university course after August 2023 and took out a tuition fee or maintenance loan, you are on Plan 5. This is the lowest threshold of any undergraduate plan at £25,000 per year.
Use our student loan balance check guide to confirm which plan you are on if you are unsure. It affects everything from how much you pay to how long you pay it.
The Plan 2 threshold is now confirmed to freeze at £29,385 from April 2027 until April 2030. That means for three full tax years, the threshold stays static while most people’s wages continue to rise.
Here is why that matters in practical terms. Every £1,000 by which the threshold is lower than it otherwise would be costs you £90 per year in extra repayments (9% of £1,000). That sounds small. Over a 30-year repayment window, that same £1,000 difference amounts to £2,700. When the threshold stays frozen for multiple years while wages rise, a progressively larger slice of your income falls above the threshold and gets deducted.
The earlier freeze between 2021/22 and 2024/25 cost the average Plan 2 borrower between £3,000 and £6,000 in additional repayments over their loan lifetime, depending on salary trajectory. That money is gone. It cannot be recovered.
Defaulting on your payments is a direct violation of the UK student loan terms and conditions.
Overseas Borrowers: Arrears, Enforcement, and What to Do
If you have lived or are currently living outside the UK, this section is specifically for you.
Why Overseas Arrears Build Up Faster
When you leave the UK for more than three months, you are supposed to update your employment details with SLC. If you do not, SLC has no income information for you. Instead of stopping your repayments, they apply a fixed monthly rate. That rate compounds every month you do not pay it.
The scale of this problem is significant. Around £2.5 billion in UK student loan debt is held by overseas-based borrowers, with a collection rate of just 6.8%. SLC’s response to that gap is changing from 2026. They are increasing legal cases by 50% this year, using credit bureau reporting in multiple countries, and in some cases using investigators to locate borrowers who have not made contact.
Voluntary contact is always better than enforced contact. If you are overseas and have not been making repayments or submitting income assessments, get in touch with SLC before they come to you.
Returning to the UK With Arrears
When you come back to the UK and start a job, PAYE will restart your regular deductions. But those deductions do not clear the arrears. They run in parallel. You will owe both.
Contact SLC as soon as you return, before your first payslip. Request a full arrears breakdown, understand the total, and set up a repayment arrangement before PAYE fully processes. That order matters. It gives you a clearer picture of what you are dealing with and more control over the arrangement.
If you were living overseas with student loan obligations and your income genuinely fell below the threshold for your country of residence, you had the right to pay nothing during that period. The issue is that SLC applied default charges because they had no information. That is what you need to challenge with evidence.
Financial strain can be particularly heavy if you are repaying more than one student loan, as multiple thresholds may apply.
How to Deal With an Arrears Balance
If you already have arrears on your account, the most important thing is to contact SLC directly. The longer you wait, the more interest accrues and the more enforcement options become available to them.
The SLC Arrears Enquiries team handles repayment plans. Before you call them, have the following ready:
- Your customer reference number (on any letter from SLC)
- Proof of your current income (recent payslips or bank statements)
- If the arrears are from an overseas period, any income evidence you have from that time
SLC will ask about your financial situation and agree on an instalment arrangement based on what you can realistically pay. This is separate from your PAYE deductions. Even if you are employed, and deductions have restarted, the arrears must be paid on top as a direct payment to SLC.
The arrangement is flexible. If your income changes, you can contact SLC to revise the plan. They are not supposed to set an arrangement that pushes you into hardship.
If SLC applied a default monthly rate during a period when you were overseas and your actual income was below the repayment threshold for that country, you may have grounds to request a recalculation.
The fixed default rate for overseas borrowers, which can reach £618.80 per month, is applied when SLC has no income information. If you can show your real income was lower than what would have triggered repayments, SLC should be able to adjust the arrears figure.
You will need:
- Pay slips, tax returns, or employer letters from the overseas period
- Bank statements showing the income you actually received
- The dates you were based overseas
This is not guaranteed, and SLC’s decision is not always fast. But it is worth doing before you agree to repay a figure that may not be accurate.
If your arrears are large and you are struggling to see a clear path, speak to a free debt adviser before you sign any arrangement. This will not affect your credit score, and it costs nothing.
Repaying More Than One Student Loan
Some borrowers have both an undergraduate loan and a Postgraduate Loan. The repayment rules for this situation are worth knowing, because many people assume they pay 9% plus 6% on the same income. You do not. Your repayments are calculated with both plans running at the same time, but not stacked in the same way. Here is how it works in practice:
- If you earn between the Plan 2 threshold (£29,385) and the Postgraduate threshold (£21,000 annually), you only repay on the Postgraduate Loan at 6%. The undergraduate plan does not trigger.
- If your income is above both thresholds, you repay 9% of the income above your undergraduate threshold and 6% of the income above £21,000 on your Postgraduate Loan. These are separate calculations applied to the same income, not combined into a 15% rate.
That is a meaningful combined deduction. Our student loan repayment calculator can work through this for your exact income and loan combination. If you are in this position and also making salary sacrifice pension contributions, the interaction between all three is worth modelling carefully.

Frequently Asked Questions
Can I reduce my student loan repayments if I am struggling financially?
Yes. If your income is below your plan’s repayment threshold, deductions should stop automatically through PAYE. If you are self-employed, you need to reflect that in your Self Assessment return.
What is an arrears balance on a student loan?
It is the specific portion of your student loan debt that is overdue. Arrears are payments you were supposed to make and did not. They are handled separately from your regular PAYE deductions and must be repaid directly to SLC in addition to your ongoing repayments.
Does being in arrears affect my credit score?
It can. SLC can report arrears to credit reference agencies, and if they pursue a County Court Judgement, that will appear on your credit file for six years. The risk only arises when repayments are missed, and SLC escalates.
Can I pause student loan repayments if I move overseas?
Your PAYE deductions stop automatically when you leave UK employment. But if your overseas income is above the threshold for your country of residence, you are still expected to make repayments directly to SLC.
Do pension contributions reduce student loan payments?
It depends on the type of contribution and how you are employed. Salary sacrifice pension contributions reduce your NICable income, so they do reduce your monthly payment through PAYE. Standard pension contributions through relief at source do not directly affect your PAYE deduction.
What is the student loan repayment threshold freeze?
The Plan 2 threshold is confirmed to freeze at £29,385 from April 2027 to April 2030. A frozen threshold means your repayments grow in real terms every year, because the threshold stays flat while wages typically rise.
Can I get a refund if I have overpaid my student loan?
Yes, but only if your total annual income for the year was below your plan’s annual threshold. If your income dropped during the year but you still ended the year above the threshold overall, you are not entitled to a refund. Contact HMRC after April 5 at the end of the tax year to request a refund if you think you qualify.
Can I repay my student loan early to reduce the balance?
Yes. You can make voluntary repayments at any time directly to SLC. These reduce your balance, which in turn reduces the amount on which interest is calculated.
