Payroll 2026 · Plan 5 default

Employee cannot confirm their student-loan plan? Use the 2026 default only until authoritative details arrive.

Keep the starter answer, account confirmation, payroll setup and later SL1 as separate evidence. A temporary default must not become a permanent undocumented setting.

Direct answer

HMRC guidance says that from 6 April 2026, if an employee with a student loan cannot identify Plan 1, 2 or 4, payroll uses Plan 5 until an SL1 provides the correct plan; multiple plans use the lowest recovery threshold until notice.

Current HMRC notices, payroll software and GOV.UK guidance control. This is not payroll or tax advice.
