A worked Plan 2 example
Using an annual planning method, subtract the threshold from repayment income and apply 9% to the remainder. Payroll performs the calculation separately for each pay period, so bonuses and irregular earnings can make the actual annual deduction different.
Example: At £35,000, the amount above the Plan 2 threshold is £5,615. Nine per cent is about £505 for the year before pay-period rounding.

Why the deduction is not Income Tax
Student-loan deductions appear beside tax and National Insurance on a payslip, but they are a separate repayment. Do not add them to PAYE Income Tax deducted when estimating an Income Tax refund.
If you are self-employed, the repayment can be collected through Self Assessment. Check that the correct plan is recorded when employment and Self Assessment income are combined.

Frequently asked questions
How do I know my plan?
Check your Student Loans Company account or official correspondence rather than guessing from your age.
Can I repay an undergraduate and postgraduate loan together?
Yes. Both deductions can apply when income exceeds their respective thresholds.
Why does payroll differ from an annual calculator?
Payroll uses each pay period and rounds under PAYE rules; an annual tool provides a planning estimate.
