Student Loans Thresholds, Rates and Loan Start Notices

Posted on 16th February 2023 by Joanne Stoneman

That the new student loan plan and postgraduate loan thresholds and rates from 6 April 2023 are as follows:

  • plan 1: £22,015
  • plan 2: £27,295
  • plan 4: £27,660
  • postgraduate loan: £21,000

Deductions for:

  • plans 1, 2 and 4 remain at 9% for any earnings above the respective thresholds
  • postgraduate loan remains at 6% for any earnings above the respective threshold

If you receive a student loan and or postgraduate loan start notice (SL1/PGL1) from HMRC for an employee, it is important that you check and use the correct:

  • loan or plan type on the start notice
  • start date shown on the notice

This makes sure that the employee’s do not pay any more or less than they have to.

If the employee’s earnings are:

  • below the respective student loan and postgraduate loan thresholds, you should update the employee’s payroll record to show they have a student loan and or postgraduate loan and file the start notice — you do not need to return this to HMRC
  • above the respective student loan and postgraduate loan thresholds, and deductions have not been taken, HMRC will send a generic notification service prompt as a reminder — if deductions still haven’t started, we may contact you directly


Deductions should continue until HMRC notifies to stop.
