Payroll · previous tax year

Student loan over-deducted last tax year? Separate payroll evidence from refund route.

A previous-tax-year student loan over-deduction is not the same as a current payroll adjustment. Build a packet with payslips, P60, notices, FPS history and the route HMRC or the Student Loans Company expects.

Direct answer

GOV.UK employer guidance distinguishes payroll notices, employee declarations and correction routes; previous-year deductions need careful evidence before a refund path is chosen.

HMRC, SLC, payroll software and official notices control. This page is an operational checklist, not payroll or tax advice.

Source base: student and postgraduate loan employer guidance, GOV.UK new employee student loans and correcting FPS or EPS errors.

Year boundary

Do not treat it like current payroll.

Closed-year payroll data often has different correction mechanics.

Loan plan

Plan type matters.

A plan mismatch can look like an over-deduction until the source notice is reviewed.

Limit

Escalate disputes.

Leavers, multiple jobs or year-end corrections may need HMRC, SLC or provider support.
