Student Loan Repayment Explained for NHS Staff (Plan 1/2/4/5)

This guide sits in our NHS Tax Relief & Expense Claims hub, and it's aimed squarely at the confusion most NHS staff run into with student loan repayment: not understanding which of the several plan types applies to them, not realising the threshold changes every tax year, and not having a straight answer to the genuinely debated question of whether paying it off early is worth doing. None of this is NHS-specific policy — it's the general UK student loan repayment system — but NHS staff are a large group of PAYE employees for whom this deduction is a real, recurring line on their payslip, so it earns its own clear explanation here.

How student loan repayment actually works through PAYE

If you're an NHS employee, your student loan repayment is handled entirely through your trust's payroll system, on instruction from HMRC — it works in a broadly similar way to how Income Tax and National Insurance are deducted, but it is a distinct deduction with its own rules:

• ✓ HMRC tells your employer which student loan plan (or plans) you're on, based on information from the Student Loans Company or SAAS
• ✓ Each pay period, payroll checks your gross qualifying pay for that period against a pro-rated share of your plan's annual threshold
• ✓ If your pay for that period is above the pro-rated threshold, 9% of the amount above it is deducted (6% for a Postgraduate Loan) and passed to HMRC, who forward it to the Student Loans Company
• ✓ This happens automatically — you don't submit anything to trigger it, and it appears as a distinct line on your payslip alongside Income Tax, National Insurance and any pension contribution

Because it's calculated per pay period rather than as a single annual figure, a month with extra unsocial-hours pay, overtime, or a one-off payment can trigger a deduction even if your average annual earnings sit below the yearly threshold — and a quieter month might see no deduction at all. Over a full tax year, this generally settles close to what you'd owe based on your true annual income, but it's a common source of "why did this appear on my payslip this month" confusion, particularly for staff whose hours or unsocial-hours pay vary significantly month to month.

The different plan types relevant to NHS staff

There are five distinct repayment plans that can apply to UK student loan borrowers, and NHS staff — a workforce spanning decades of different entry points into higher education, across all four UK nations — are about as likely as any group to have a genuine mix of all of them:

• ✓ Plan 1 — generally English and Welsh students who started an undergraduate course before September 2012, and most Scottish and Northern Irish undergraduate borrowers regardless of start date (Scotland's separate Plan 4 applies specifically to SAAS-funded students)
• ✓ Plan 2 — English and Welsh students who started an undergraduate course between September 2012 and July 2023
• ✓ Plan 4 — Scottish students whose undergraduate loans are funded by the Student Awards Agency for Scotland (SAAS)
• ✓ Plan 5 — English and Welsh students starting an undergraduate course from August 2023 onwards, replacing Plan 2 for new borrowers
• ✓ Postgraduate Loan — a separate plan for Master's or Doctoral loans, which sits on top of whichever undergraduate plan (if any) you also have, with its own independent threshold

It's entirely possible — common, even, among NHS staff who returned to study for a postgraduate qualification later in their career, such as an Advanced Clinical Practice Master's — to be repaying an undergraduate plan and a Postgraduate Loan simultaneously, each assessed independently against its own threshold.

Current repayment thresholds and rates (2026/27)

Thresholds are reviewed and can change each tax year, so treat any student loan figure you see online — including this one, over time — as something worth double-checking against GOV.UK if it's more than a year or two old. For the 2026/27 tax year, the confirmed thresholds are:

• ✓ Plan 1: £26,900 a year — repay 9% of income above this
• ✓ Plan 2: £29,385 a year — repay 9% of income above this (the government has confirmed this threshold will remain frozen at £29,385 from April 2027 through to April 2030, rather than rising with inflation)
• ✓ Plan 4 (Scotland): £33,795 a year — repay 9% of income above this
• ✓ Plan 5: £25,000 a year — repay 9% of income above this
• ✓ Postgraduate Loan: £21,000 a year — repay 6% of income above this, independently of any undergraduate plan

What this looks like against real NHS salaries

Thresholds are easier to make sense of against actual Agenda for Change figures rather than as abstract numbers, so here's roughly how the plans line up against common NHS pay points (using basic salary only — unsocial-hours pay, overtime and enhancements would push actual gross pay, and therefore the repayment calculation, higher still):

• • A newly qualified Band 5 nurse's basic salary sits close to, and in some cases above, the Plan 5 threshold (£25,000) — meaning many new graduates on Plan 5 start seeing a small deduction almost immediately, whereas the same salary would trigger no deduction at all for someone on Plan 1 (£26,900) or Plan 2 (£29,385)
• • A Band 6 salary comfortably clears the Plan 5 and Postgraduate thresholds, and typically clears or sits close to the Plan 1 threshold too, meaning most Band 6 staff on any plan will see at least some deduction most months, with the exact amount depending heavily on which plan applies
• • A Band 7 salary clears all five thresholds in most cases, meaning the specific plan mainly affects how much is deducted rather than whether anything is deducted at all
• • This is exactly why two colleagues on the identical Band and pay point can see meaningfully different take-home pay purely because of which student loan plan each happens to be on — a genuinely common source of payslip confusion between colleagues comparing notes

If you want the precise figure for your own band, pay point and plan rather than this rough illustration, our NHS Pay Calculator runs the actual calculation, including any unsocial-hours pay you add, against whichever plan you select.

How to check which plan applies to you if you're unsure

Given how many staff genuinely don't know their own plan type — understandably, since it depends on exactly when and where you started a course, sometimes decades ago — the most reliable ways to check are:

• • Log into your online account at GOV.UK's student loan balance service (or the SAAS portal if you believe you're Plan 4) — your plan type is stated directly alongside your current balance
• • Check a recent payslip once repayments have started — most NHS payroll systems display which plan is being applied
• • Ask your NHS trust's payroll team, who can confirm what HMRC's instruction to them currently states
• • As a rough (not definitive) guide by start date: before September 2012 in England/Wales generally means Plan 1; September 2012 to July 2023 generally means Plan 2; August 2023 onwards generally means Plan 5 — but transitional cases exist, so treat this as a starting point for checking, not a final answer

Self-employed and mixed-income NHS staff

If some or all of your income is genuinely self-employed — locum work outside PAYE, private practice, training delivery — student loan repayment on that income isn't deducted in real time through payroll. Instead, it's calculated once a year through Self Assessment, based on your total profit (and any other income) for the tax year, and paid alongside your Income Tax and Class 2/4 National Insurance by the 31 January deadline. If you have both PAYE NHS employment and self-employed income in the same tax year, the employed portion continues to have student loan repayment deducted through payroll as normal, while the self-employed portion is reconciled separately through your return — see our NHS locum and self-employed tax basics guide for the fuller picture of Self Assessment obligations that come with self-employed income.

Should you make voluntary overpayments?

This is a genuinely debated personal finance question, and it deserves a straight answer rather than a one-line platitude in either direction: it depends on your individual circumstances, and there is no universal "always overpay" or "never overpay" rule that applies to everyone.

The core consideration is whether you'd realistically clear your balance in full before it's written off at the end of your plan's repayment term (commonly cited as around 25 years for Plan 1, 30 years for Plan 2 and Plan 4, roughly 30 years for the Postgraduate Loan, and around 40 years for Plan 5 — check your own account for your specific write-off date, since individual terms vary). This matters because UK student loans function much more like a graduate tax than a conventional debt for many borrowers:

• ✓ If you're on track to never fully repay the balance before it's written off — a realistic outcome for many Plan 2 and Plan 5 borrowers on NHS-scale salaries, given how long those terms run — voluntary overpayments generally just mean paying HMRC/the Student Loans Company money you'd otherwise never have had to pay at all, since the remaining balance would have been cancelled regardless
• ✓ If you're confident you're on track to fully repay well before the write-off date — more plausible for Plan 1 borrowers with a shorter remaining term, or anyone with a smaller original balance and strong income growth — overpaying can make sense in the same way overpaying any other debt does, since you're simply repaying the same total sooner and reducing the interest that accrues on the outstanding balance in the meantime
• ✓ The interest rate charged on your specific plan also matters — check your current rate via your online account, since it varies by plan and by income level for some plans, and compare it honestly against what you could otherwise do with the same money (e.g. an NHS Pension is a defined benefit scheme most staff should generally prioritise over discretionary loan overpayments; a high-interest debt elsewhere might reasonably come before either)
• ✓ There's no partial-credit mechanism that rewards early repayment beyond reducing the interest that accrues — so the "will I ever actually clear this?" question really is the central one

We're not going to pretend there's a single correct answer here, because there genuinely isn't one — a Band 8 NHS manager on Plan 1 with a small remaining balance is in a completely different position from a newly qualified Band 5 nurse on Plan 5 with a full undergraduate balance and 40 years on the clock. If you're seriously considering a substantial voluntary overpayment, it's worth running your own numbers (or getting independent financial advice) rather than following generic "always overpay debt" advice that doesn't account for the write-off mechanism specific to UK student loans.

Why you can rely on this page

• ✓ The 2026/27 thresholds quoted (Plan 1 £26,900, Plan 2 £29,385, Plan 4 £33,795, Plan 5 £25,000, Postgraduate £21,000) reflect the current confirmed figures for this tax year, checked rather than carried over from a prior year
• ✓ We flag explicitly that Plan 2's threshold is now frozen through to April 2030 rather than assume it will rise with inflation, since a frozen threshold changes the maths for anyone budgeting several years ahead
• ✓ We give a genuinely balanced answer on voluntary overpayments rather than a false universal rule, because the write-off mechanism means the right answer really does depend on individual circumstances

Frequently asked questions

Frequently asked questions

How do I actually find out which student loan plan I'm on? +

The most reliable way is to log into your online account at gov.uk/sign-in-to-manage-your-student-loan-balance (or the equivalent Student Awards Agency for Scotland account for Plan 4), where your plan type is stated directly alongside your balance. As a rough guide, if you started an undergraduate course in England or Wales before September 2012 you're very likely Plan 1; between September 2012 and July 2023, Plan 2; from August 2023 onwards, Plan 5; Scottish students funded by SAAS are generally Plan 4; and a separate Postgraduate Loan plan applies to Master's or Doctoral loans taken out for postgraduate study, on top of whichever undergraduate plan you also have. If you're still unsure, your payslip will show which plan is being applied once repayments start, and your employer's payroll team can also confirm what HMRC has instructed them to deduct.

Why do repayments suddenly start or stop as my NHS pay changes? +

Student loan repayment through PAYE is calculated on your pay in each individual pay period against a pro-rated version of the annual threshold, not on your annual salary as a fixed fact. This means if you pick up extra unsocial hours, overtime or an additional shift in a particular month that pushes your gross pay for that period above the threshold, a deduction can appear in that pay period even if your average annual earnings are below the yearly threshold — and conversely, a quiet month can mean no deduction at all. Over a full tax year this generally evens out close to what you'd owe based on annual income, but it can look inconsistent month to month, which is one of the most common sources of confusion on NHS payslips.

Do I pay off my Postgraduate Loan and undergraduate loan (Plan 1, 2, 4 or 5) separately? +

Yes — if you have both an undergraduate plan and a Postgraduate Loan, they're assessed and repaid independently, each against its own threshold, and both deductions can apply in the same pay period once your income crosses both thresholds. Your undergraduate plan is repaid at 9% of income above its threshold, and the Postgraduate Loan separately at 6% of income above its own £21,000 threshold — so someone with both plans active and earning comfortably above both thresholds could see a combined 15% deducted from the portion of pay above the higher of the two thresholds, which is worth being aware of if you're budgeting around a pay rise or promotion.

Does student loan repayment affect my NHS Pension contributions or take-home pay differently to Income Tax? +

Student loan repayments are calculated on your gross pay for National Insurance purposes (broadly, pay after pension contributions but before Income Tax), similarly to how National Insurance itself is calculated, rather than on your taxable pay after all deductions. It's deducted alongside Income Tax and National Insurance as a separate line on your payslip, but it isn't itself a tax — it doesn't affect your tax code, and repaying doesn't reduce your taxable income the way, for example, pension contributions do. It's simply a fixed percentage of qualifying earnings above your plan's threshold, collected automatically by your NHS trust's payroll on HMRC's instruction.

If I move from NHS employment to self-employed locum work, does my student loan repayment change how it's collected? +

Yes — for self-employed income, student loan repayment isn't deducted from pay in real time the way PAYE does it. Instead, it's calculated once a year through Self Assessment, based on your total self-employed profit (and any other income) for the tax year, and paid alongside your Income Tax and National Insurance by the 31 January Self Assessment deadline. If you have both employed NHS income and self-employed locum income in the same year, both are taken into account, though the employed portion continues to be deducted through payroll as normal while the self-employed portion is reconciled through your return — see our <a href="/tax-relief/nhs-locum-self-employed-tax-basics/">NHS locum and self-employed tax basics guide</a> for the wider Self Assessment picture.

Will my student loan definitely be written off eventually if I don't finish repaying it? +

Yes, in the sense that all UK student loans have a fixed write-off point, typically a set number of years after you became eligible to start repaying (commonly cited as 25 years for Plan 1, 30 years for Plan 2 and Plan 4, and around 30 years for the Postgraduate Loan, with Plan 5 running considerably longer at around 40 years) rather than running indefinitely — though the exact date depends on your individual circumstances and the terms that applied when you took the loan out, so check your online account for your specific write-off date rather than relying on a generic figure. Outstanding balances at that point are cancelled rather than becoming due in full.

Should NHS staff on lower bands worry about student loan repayment affecting affordability? +

It's a genuine budgeting factor worth including honestly rather than glossing over, particularly around Band 5/6 pay points where earnings sit close to some plan thresholds — a modest pay increase or a period of extra unsocial-hours pay can be the difference between no deduction and a real one appearing on a payslip. It isn't something to be alarmed by (it only ever applies to income above the threshold, never below it), but it's exactly the kind of deduction that catches people off guard if they've only ever mentally budgeted around Income Tax, National Insurance and pension contributions. Our <a href="/calculators/nhs-pay-calculator/">NHS Pay Calculator</a> lets you select your plan type so you can see the effect on your specific take-home figure rather than guessing.

Can I ask HMRC or my employer to stop deductions if I think I've already repaid in full? +

If your loan balance reaches zero, the Student Loans Company is meant to notify HMRC, who then instruct your employer to stop deductions — but this process can lag, and it's a well-documented source of genuine overpayment for borrowers who are close to clearing their balance. If you believe you're close to or at zero, it's worth monitoring your online loan account directly and, if deductions continue after your balance shows as repaid, contacting the Student Loans Company yourself rather than assuming payroll will catch it automatically. Any confirmed overpayment is refundable.

Do NHS Pension salary sacrifice or other salary sacrifice schemes reduce my student loan repayment? +

Yes, to the extent they reduce your gross qualifying pay. Salary sacrifice arrangements — such as some NHS car lease or additional pension contribution schemes — reduce your headline salary in exchange for a non-cash benefit, and since student loan repayment (like National Insurance) is calculated on your actual pay after salary sacrifice, a genuine salary sacrifice arrangement can modestly reduce the student loan repayment taken in a given period, in the same way it can reduce National Insurance. This is a side effect of how salary sacrifice works generally, not a scheme specifically designed around student loans, and shouldn't be the main reason to enter into one.

Is it worth contacting the Student Loans Company directly if something on my payslip looks wrong? +

Yes — if a deduction looks inconsistent with your understanding of your plan, threshold or balance, the Student Loans Company (or SAAS for Plan 4) can confirm exactly what HMRC has instructed your employer to deduct and reconcile it against your account, which is more reliable than trying to work it out from payslip figures alone. Payroll teams deduct exactly what HMRC's coding notice tells them to — if the underlying instruction is wrong, payroll correcting the payslip without HMRC correcting the instruction first won't actually fix the ongoing issue.
