Student loan deductions for employers

How to calculate and process student loan and postgraduate loan deductions from employee pay.

Guide summary

Deduct student loan or postgraduate loan repayments from employees' pay when HMRC tells you to or when a new employee says they have a loan on their starter checklist. The amount depends on their loan plan and how much they earn above a set threshold. Do not stop deductions until HMRC sends you an official stop notice.

  • Start deductions when HMRC sends SL1 or PGL1 notice, or starter checklist says loan
  • Deduct 9% of earnings above threshold for Plans 1, 2, 4, 5
  • Deduct 6% of earnings above £21,000 for postgraduate loan
  • Plan 1 threshold: £26,900 per year (2026/27)
  • Plan 2 threshold: £29,385 per year (2026/27)
  • Plan 4 threshold: £33,795 per year (2026/27)
  • Plan 5 threshold: £25,000 per year (2026/27)
  • Postgraduate loan threshold: £21,000 per year (2026/27)
  • Stop deductions only when HMRC sends SL2 or PGL2 notice, or employee leaves
  • Report deductions each pay period on your Full Payment Submission

Pay PAYE to HMRC

How and when to pay your PAYE tax and National Insurance to HMRC.

As an employer, you must deduct student loan and postgraduate loan repayments from employees' pay when instructed by HMRC or when notified through a starter checklist. This guide covers the thresholds, rates, and procedures for making these deductions correctly.

When to start deductions

You must begin deducting student loan repayments when you receive one of the following:

  • SL1 notice from HMRC: Start notice specifying the loan plan type
  • PGL1 notice from HMRC: Start notice for postgraduate loan deductions
  • Starter checklist: New employee indicates they have a student or postgraduate loan
  • Generic notification: HMRC coding notice indicating student loan deduction

Important: Start deductions from the next available pay period after receiving the notice. Do not backdate deductions.

Multiple loan types

An employee may have both a student loan (Plan 1, 2, 4, or 5) and a postgraduate loan at the same time. In this case:

  • Deduct both: Calculate each deduction separately against its own threshold
  • Maximum combined rate: 9% for the student loan plus 6% for the postgraduate loan (15% total of earnings above respective thresholds)
  • Protected earnings: Total deductions must not reduce pay below the National Minimum Wage

When to stop deductions

Stop deducting student loan repayments only when:

  • SL2 notice from HMRC: Official stop notice for student loan
  • PGL2 notice from HMRC: Official stop notice for postgraduate loan
  • Employee leaves: Make final deduction and include on leaving FPS

Warning: Do not stop deductions because an employee tells you their loan is repaid. Always wait for official HMRC notification. Stopping early makes you liable for the missed deductions.

Reporting student loan deductions

Student loan deductions are reported to HMRC through your normal RTI submissions:

  • FPS: Include student loan and postgraduate loan deductions each pay period
  • Year-to-date totals: Running total of deductions reported on each FPS
  • P60: Annual total shown on employee's P60 certificate
  • Leavers: Final deduction amount included on leaving FPS
