PayBreakdown

Does student loan come off before tax?

Student loan repayments are separate payroll deductions. They do not work like pension deductions and do not replace PAYE Income Tax or National Insurance.

The short answer

Student loan repayments do not normally reduce taxable pay in the way some pension methods can. In a 2026/27 payslip-style estimate, Income Tax, National Insurance and student-loan deductions are separate lines, with loan deductions based on the relevant plan threshold and pay period.

How it usually appears on a payslip

The student-loan deduction sits alongside other payroll deductions. It is not the same as Income Tax, and it is not normally a pension-style reduction to taxable pay.

  • PAYE Income Tax is calculated from taxable pay and the tax code.
  • Employee National Insurance is calculated separately under NI rules.
  • Student loan and postgraduate loan deductions are then calculated from earnings above the relevant plan threshold.
  • A bonus or overtime payment can increase the loan deduction for a single pay period.

What to check before comparing

A calculator comparison only works if it uses the same plan and pay-period assumptions as payroll.

  • Check whether the payslip shows student loan, postgraduate loan, or both.
  • Use the plan from Student Loans Company or payroll records where possible.
  • Compare the pay period, not just the annual salary.
  • Remember that start and stop notices can create timing differences.

Frequently asked questions

Does student loan reduce taxable income?

Not in the same way as net pay or salary sacrifice pension methods. Student loan is normally a separate deduction based on income above the relevant plan threshold.

Does student loan come off before National Insurance?

Treat it as a separate payroll deduction. Income Tax, National Insurance and student loan each have their own rules and thresholds.

Why did student loan change when my tax did not?

The loan deduction can change because pay crossed a plan threshold in that period, because of bonus or overtime, or because payroll received a start or stop notice.
