US student loans while living in the UK: the tax side

Who can claim the student loan interest deduction as an expat

Yes, if the ordinary conditions are met. Living in the UK does not remove the deduction. Publication 970 requires a filing status other than married filing separately, that nobody else claims you as a dependant, that you are legally obliged to pay interest on a qualified student loan, and that you actually paid it in the year.

A qualified student loan is one taken out solely to pay qualified education expenses for you, your spouse or your dependant, while the student was enrolled at least half-time in a programme leading to a degree or other recognised credential. Federal Direct Loans for a US degree normally meet that test. A loan from a relative or an employer's retirement plan does not.

The deduction is an adjustment to income on Form 1040 (opens the official IRS page in a new tab), so it is available without itemising. It is capped at a fixed amount of interest each year and is reduced across a band of modified adjusted gross income, disappearing above it. Interest your servicer adds to the balance becomes deductible only as later payments go towards principal, so a year in which nothing is paid gives no deduction for that interest. Our Form 1040 page shows where it sits.

Why married filing separately shuts the deduction off

Because the rule says so, with no exception for couples living abroad. Publication 970 allows the deduction on any filing status except married filing separately. A US citizen married to a British spouse who files separately, which is the common choice, cannot claim it at all, however modest their income.

Two other statuses can reopen it. A US citizen married to a non-resident spouse can be treated as unmarried for head of household purposes where they pay more than half the cost of a home for a qualifying child. Alternatively, the couple can elect to treat the British spouse as a US resident and file jointly.

The joint election is rarely worth making for this deduction alone. It brings the spouse's worldwide income, UK accounts and any UK funds into the US system, and that joint income is then measured against the phase-out band. Our post on filing status for Americans married to a non-US spouse sets out the wider trade-off. Where the couple already file jointly for other reasons, the deduction comes with it.

Why the exclusion does not help you pass the income test

Because it is added back. For Form 1040 filers, Publication 970 measures modified AGI as AGI before the student loan interest deduction, plus any foreign earned income exclusion, foreign housing exclusion and foreign housing deduction. Excluding a UK salary on Form 2555 therefore does not bring a borrower under the limit.

So the income test sees the full UK salary whichever method you use. An American on a salary well inside the foreign earned income exclusion (opens the official IRS page in a new tab) limit of ${FACTS.feie.v} for 2025 can still be above the phase-out band once the excluded pay is added back. The choice between Form 2555 (opens the official IRS page in a new tab) and the credit moves nobody across the line.

What the deduction is worth differs. Under the exclusion, the salary has left taxable income, so the deduction can reduce tax only on whatever income remains, such as UK bank interest or a US rental. Under the credit, UK income tax usually exceeds the US tax on the same earnings, so US tax on the salary is already nil. A deduction against income that bears no US tax often saves nothing in the current year, though it can change the foreign tax credit limit on Form 1116 (opens the official IRS page in a new tab) and the amount of unused UK tax carried ${FACTS.ftcCarry.v}.

How the exclusion and the credit change the AGI a repayment plan sees

Very differently. The Department of Education's income-driven plans, and the Repayment Assistance Plan introduced in July 2026, generally work from the adjusted gross income on your federal return. The exclusion removes UK earnings from AGI. The foreign tax credit leaves the full salary in AGI and reduces only the tax.

This is where the two methods diverge for a borrower. On the tax side, a UK higher-rate employee may owe nil US tax on the salary under either method. On the repayment side, the same person reports a far lower AGI under the exclusion than under the credit, and the monthly payment is calculated from that figure.

That does not make the exclusion the right answer. The credit keeps unused UK tax as a carryover, and the exclusion wastes the UK tax on excluded pay. Revoking an exclusion election bars re-electing it for five years without IRS consent, and a parent claiming it loses the refundable part of the child tax credit. The repayment rules themselves, including how a spouse's income is treated, are set by the Department of Education and are outside this post. Our article on choosing between the credit and the exclusion in the UK covers the tax half of the decision.

Is forgiveness of a federal student loan taxable from 2026

Often, yes. The American Rescue Plan Act excluded most student loan forgiveness for discharges in 2021 through 2025, and that exclusion has ended. The Taxpayer Advocate Service says forgiveness under an income-driven repayment plan in 2026 or later is generally treated as taxable cancellation of debt income.

Some forgiveness stays outside income. The Taxpayer Advocate Service lists Public Service Loan Forgiveness, Teacher Loan Forgiveness and discharges because of death or total and permanent disability as creating no tax liability. A borrower who was insolvent when the debt was cancelled, meaning liabilities exceeded the value of assets, may exclude some or all of it on Form 982. The servicer may issue a Form 1099-C early in the following year, and the amount belongs on the return for the year of cancellation.

Living in the UK does not change any of this. Cancelled debt is not pay for work, so the foreign earned income exclusion cannot remove it, and a borrower who has relied on the exclusion for years may face a US bill in the forgiveness year that the exclusion cannot reduce. We review forgiveness cases as part of our individual tax returns work, including whether the insolvency exclusion applies.

• Income-driven forgiveness in 2026 or later: generally taxable
• Discharges in 2021 through 2025 covered by the American Rescue Plan Act: generally excluded
• Public Service Loan Forgiveness and Teacher Loan Forgiveness: no tax liability
• Death or total and permanent disability discharge: no tax liability
• Insolvent at cancellation: possible exclusion on Form 982

Does the UK give tax relief for US student loan interest

No. HMRC gives income tax relief on loan interest only where the money was borrowed for specific purposes listed in its helpsheet on qualifying loans, such as buying into a partnership or a close company, or buying equipment used for work. Education loans are not among them, from any country.

So the interest on a US federal loan does not appear on a UK return at all. There is no box for it on the SA100, and it does not reduce the UK income tax that later becomes your foreign tax credit. HMRC's helpsheet also says interest on overdrafts and credit cards cannot be relieved, so refinancing the debt onto a UK card or personal loan does not change the answer.

Nor does a US federal loan produce the student loan line seen on UK payslips. That deduction collects loans from the Student Loans Company through payroll, while a US servicer is paid directly. A borrower who files a UK return through Self Assessment reports UK income and gains as usual and leaves the US loan off it entirely.

A worked example and a decision table

Take a US citizen employed as a research scientist in Cambridge, married to a British spouse, with federal Direct Loans from a US graduate programme on an income-driven plan. She files married filing separately and uses the foreign tax credit. Her UK income tax exceeds the US tax on her salary, so her US tax is nil.

She cannot take the student loan interest deduction, because her filing status bars it. If she switched to the exclusion, her modified AGI for the deduction would be unchanged, since the excluded pay is added back, and her status would still bar it. Her reported AGI would fall, which would reduce the income her repayment plan works from, but she would waste the UK tax on excluded pay, and if she later revoked the exclusion to return to the credit, she could not elect it again for five years without IRS consent.

Her later forgiveness, if it comes under an income-driven plan, would be taxable in the year of discharge unless an exclusion applies, and neither method on her return would shelter it. Our cross-border tax work models both methods, using Form 2555 or Form 1116, before the choice is made. The guide for Americans in the UK covers the wider return, and Publication 54 (opens the official IRS page in a new tab) is the IRS's own reference. Use the table below to see where you stand:

• Married filing separately, any income: no deduction; check the joint election only for wider reasons
• Single or head of household, full UK salary inside the phase-out band: deduction reduced or nil
• Single or head of household, income below the band, using the credit: deduction allowed but may save nothing this year
• Using the exclusion to lower a repayment: weigh lost carryovers and the five-year bar first
• Forgiveness expected in 2026 or later under an income-driven plan: plan for a taxable year
• Any status: no UK relief for the interest on the SA100
