Repaying Your UK Student Loan Abroad: Thresholds, Fixed Charges and the 3-Month Rule

The trigger is short absence, not permanent emigration. GOV.UK's rule is that you must tell SLC if you are leaving the UK for more than 3 months, and the student loan terms and conditions add that you must let SLC know before you leave (GOV.UK). Three months is far below any tax residence test, so people who remain UK tax resident all year, on a secondment or a trial move, are still inside the notification duty. Whether you actually break UK tax residence is a separate question answered by the Statutory Residence Test, and the two do not move together.

Notification is done through your online repayment account, where you update your employment details and give SLC information about your income abroad; SLC then works out a monthly repayment based on your country's threshold. The duty applies in reverse too: when you come back after more than 3 months away, update your details again so deductions restart correctly, otherwise you can carry on being charged at the overseas rate and overpay (GOV.UK).

Do this alongside the rest of your departure admin: the forms and refunds that matter when you leave, the P85, your final Self Assessment return and any split year claim all run to their own deadlines, and the SLC notification is the one with no form number that people miss.

Everything abroad is priced off the UK threshold for your plan, so start there. For 2026/27 the UK thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for a Postgraduate Loan, with repayments at 9% of income over the threshold for Plan 1, 2, 4 and 5 and 6% for a Postgraduate Loan (GOV.UK).

If you hold two loans, say a Plan 2 undergraduate loan and a Postgraduate Loan, both formulas run at once against their own thresholds, abroad exactly as in the UK.

Because living costs differ, SLC applies a different earnings threshold in each country, published annually; the current set applies from April 2026 until March 2027 and lists, for each country, the local currency, SLC's exchange rate, the sterling threshold and the fixed monthly repayment (GOV.UK). The pattern is consistent: Australia, Canada and New Zealand keep the UK threshold, the United States sits above it, most of Western Europe and the Gulf sit at roughly four fifths, and lower-cost countries step down from there.

The direction of the adjustment surprises people. A move to Dubai reads as a tax win, and for income tax it usually is, but the student loan moves the other way: a Plan 2 borrower's threshold falls from £29,385 to £23,510, so a £60,000 salary that generated £2,755 of annual repayments in the UK generates £3,284 in the UAE, while the same borrower in the United States gets a £35,260 threshold and repays £2,227 (GOV.UK).

SLC converts your local income into sterling at its published exchange rate for the year, then applies the 9% or 6% formula above the sterling threshold. The Plan 2 tables also publish an upper earnings threshold for each country, £52,885 for Australia and £63,460 for the United States, used in working out where you sit on the Plan 2 interest scale, discussed below.

The country tables carry a second number that matters more in practice than the threshold: the fixed monthly repayment, which GOV.UK describes as how much you will be charged if you do not give SLC the information it needs (GOV.UK). The terms and conditions add that it may be higher than the repayment due on your actual income (GOV.UK). It is a default assessment rather than a fine, but it behaves like one because it ignores your earnings entirely.

Run the comparison for a Plan 2 borrower in Australia earning £40,000. On evidence, the repayment is 9% of £10,615, which is £955 a year or about £80 a month. Without evidence, the fixed charge is £409 a month, £4,908 a year, more than five times as much. The evidence SLC asks for is not onerous, proof of your income such as a recent bank statement, and providing it is what switches the fixed charge off. If your income is below your country threshold the same logic runs in reverse: GOV.UK says you are expected to keep repaying unless you can give proof that your income is under the threshold (GOV.UK). Provide the proof and the monthly repayment is nil; stay silent and the fixed charge accrues anyway.

Beyond the fixed charge, the terms and conditions set out an escalation path. If you do not keep SLC informed, it can charge penalties on your loan and, where necessary, ask you to repay the full amount of the loan plus interest and penalties in one lump sum (GOV.UK). A demand for the whole balance is the last resort, but it is in the contract you signed, and years of ignored correspondence can end with arrears, fixed charges and penalties consolidated into a debt that is then pursued.

There is also a quieter cost. The same guide says that if a Plan 2 borrower does not keep in touch, an interest rate of RPI plus 3% will normally be applied to the loan whatever their income. For borrowers whose income would otherwise earn a lower rate on the Plan 2 scale, going dark means paying the maximum rate on the whole balance for as long as the silence lasts. None of this is means-tested and none of it cares that you were busy settling into a new country: the system only knows what you tell it.

In the UK the loan is invisible: your employer deducts it through PAYE. Abroad the mechanics invert. Unless you are still on a UK payroll, as some people working abroad for a UK employer are for a period, you repay SLC directly: it asks for details of your income, works out how much you should repay each month, and you pay from abroad, bearing any currency conversion costs and bank transfer fees yourself (GOV.UK).

The routine: before you leave, update your online repayment account and tell SLC where you are going and what you expect to earn. Once abroad, SLC sets a monthly figure against your country threshold and you pay it; payments can be made in the online account by debit card, bank transfer or, from overseas, international bank transfer (GOV.UK). Nothing flows through automatically: a pay rise, a pay cut or a change of country only changes your monthly figure once you give SLC the updated details, so keep your account current.

Keep records on both sides. Payslips, contracts and bank statements support your income declarations to SLC, and the same documents feed your UK departure position: day counts for the SRT, split year evidence, and any ongoing Self Assessment filings. One folder serves both, and if you are also deciding whether to keep up National Insurance from abroad, our guide to voluntary National Insurance contributions covers that parallel piece of leaver admin.

Moving abroad does not itself change your interest rate. At the time of writing GOV.UK shows interest at 3.2% for Plan 1, Plan 4 and Plan 5, 6.2% for Postgraduate Loans, and a sliding scale from 3.2% to 6.2% for Plan 2 depending on income, and it confirms that interest is still added even if you are not working or your income is below the repayment threshold (GOV.UK). For Plan 2 borrowers overseas, the country tables publish lower and upper earnings thresholds, £23,510 and £42,310 for Spain for 2026/27 for example, and your position between them feeds the same sliding scale that UK income would.

The two interest traps abroad are both behavioural. The first is the RPI plus 3% rate normally applied to a Plan 2 loan when you lose touch with SLC, covered above. The second is drift: nothing is deducted automatically, so a borrower who pays nothing for three years while interest compounds at 6.2% watches a £50,000 Plan 2 balance grow by roughly £9,900, with arrears building alongside. Neither trap exists for the borrower who files income evidence annually and pays the assessed amount.

The loan is written off at the end of its term wherever you live, and years abroad count towards the term. GOV.UK sets the write-off points by plan (GOV.UK).

Leaving the UK does not accelerate, pause or cancel any of these dates: the duty to repay follows you, only the collection mechanism changes. What the write-off date does do is set the horizon for the overpayment arithmetic below, because money paid towards a balance that would have been written off anyway is money gone.

Extra repayments are allowed at any time with no early repayment penalty. Two GOV.UK statements frame the whole decision: you cannot get a refund of any extra repayments you make, and you might not benefit from making extra repayments because your loan will be written off at the end of the loan term (GOV.UK).

So the question is purely arithmetical: will you clear the balance before write-off on mandatory repayments alone? Take a Plan 2 borrower in the UAE on a steady £60,000 equivalent with a £48,000 balance and 22 years to write-off. Mandatory repayments are £3,284 a year; at 6.2% the balance accrues roughly £2,976 of interest in year one, so it falls by only about £308 a year and plainly survives to write-off. Every voluntary pound reduces a balance that was going to be cancelled anyway, and is non-refundable. Change one number, a £6,000 balance instead, and mandatory repayments clear it in under two years, so this borrower repays in full regardless and an early lump sum simply cuts the interest paid. Same salary, same country, opposite answers.

The hard case is the borrower whose trajectory could go either way, rising income and a mid-sized balance, where small changes in salary growth or interest rates flip the answer. Run the projection with your own numbers before sending anything, and remember the asymmetry: underpaying a loan you would have cleared costs some interest, but overpaying a loan that would have been written off costs the entire overpayment. If you want the balance settled in full, SLC will give you a settlement amount and date on request. Nothing here is investment advice; it is the mechanical consequence of a non-refundable payment against a debt with an expiry date.

The student loan is one line in a longer departure checklist, and it is the tax items around it where we earn our fee: confirming your non-residence under the SRT, claiming split year treatment, filing the P85 and your final Self Assessment return, and keeping you compliant on anything you leave behind. We are a CTA-led practice specialising in UK departures, we work on fixed fees agreed upfront, from £350 for focused questions and from £750 for full departure advice, and we tell you plainly which parts of the checklist, like the SLC notification, you can do yourself in ten minutes.
