Student and postgraduate loan deductions must be carefully addressed in the ever-changing environment of UK payroll compliance. While thresholds and plan types may change each year, the principles for accurate deductions remain the same This article outlines the general rules employers should always follow when handling student and postgraduate loan deductions and provides an update on the upcoming Plan 5, set to begin in April 2026. Loan Plan Overview: An insight into the Loan Plan Structure By 2026, HMRC will operate five different student and postgraduate loan repayment schemes, each with separate eligibility criteria and deduction thresholds. Until then, during the 2025–26 tax year, only four plans (Plans 1, 2, 4, and Postgraduate Loan) are active. Employers must ensure that the correct plan type is applied according to official HMRC records, not according to assumptions. For full guidance, visit the HMRC Student and Postgraduate Loan Deductions page on GOV.UK.

It can result in over- or under-deductions, employee complaints, and potential compliance issues with HMRC. Employers should therefore verify loan plan details carefully before processing payroll. Summary Table Deduction Thresholds—2025–26 Loan Plan Annual Limit Monthly Equivalent Weekly Equivalent Deduction Rate Plan 1 £26,065.00 £2,172.08 £501.25 9% over threshold Plan 2 £28,470 £2,372.50 £547.50 9% on threshold Plan 4 £32,745 £2,728.75 £629.71 9% over threshold Plan 5 NA (until 2026) NA NA 9% (after 2026) PGL £21,000 £1,750.00 £403.85 6% over threshold Illustrative Example: A Plan 2 employee earns £30,000 per year. The amount deductible is calculated as:(£30,000 – £28,470) × 9% = £137.70 per year This equates to approximately £11.48 per month Major Compliance Risks and How to Avoid Them Improper deductions — whether over- or under-deductions — expose employers to both reputational and financial risks. Common mistakes include: 1. Failure to Apply HMRC Notices Employers must not start deductions without the related SL1 or PGL1 notice. These documents provide official guidance on repayment obligations. 2. Incorrect Plan Classification Under-deductions resulting from the misclassification of the employee plan (i.e., defaulting to Plan 1 when no plan is confirmed) can lead to significant losses. This often leads to matching issues during HMRC auditing. 3. Failure to Review Employee Declarations Not processing starter checklists or P45 can result in missing or incorrect loan declarations, leading to compliance issues. 4. Continuing Deductions After a Stop Notice As soon as the SL2/ PGL2 notice is received, the deductions should be stopped by the employer. A delay in stopping deductions may lead to employee complaints and result in overpayments. Recommendation: To maintain compliance and prevent deduction errors: Compliance-Support and Automation Tools The use of modern payroll software can help reduce manual mistakes and ensures thresholds are automatically updated. Common tools include. Among the tools commonly used by UK employers are ●      HMRC Basic PAYE Tools: Simple software that allows for manual checks. It is free and suitable for small businesses. ●      Auto-Updates Payroll Solutions: These systems have versions that communicate with HMRC and automatically update thresholds based on the latest rules. ●      SL1/PGL1 Import Tools: Some payroll platforms can automatically import HMRC notices, ensuring faster and more accurate updates. Frequently Asked Questions (FAQs) Q: How to make sure I got the right loan plan on a new staff member? A: Always check their starter checklist, P45, or the SL1/PGL1 notice. HMRC rules do not accept any guessing. Q: Can an employee have both student and postgraduate loan deductions? A: Yes. In this case, different deductions need to be calculated, 9% on the student loan and 6% on the postgraduate loan, as long as both limits are passed. Q: What happens if the wrong type of loan plan was selected? A: Extra payments must be returned quickly. If there was underpayment, then the employer is allowed to recover the amount slowly, as long as the employee agrees. Repeated mistakes may lead to fines. Q: Are there deductions during unpaid leave or when hours are reduced? A: No, repayments are only taken when the employee’s pay goes above the threshold for that pay period. Employer Strategies To achieve long-term accuracy and keep employee payments correct: ●      Centralise Documentation:Ensure all starter forms and HMRC notices are stored securely in one place for quick access. ●      Add Quality Controls:  Regularly review deduction entries, particularly after onboarding new employees or updating records. ●      Support Clear Payslips:Each payslip should clearly display deduction details to prevent confusion or disputes. ●      Stay Updated:  Subscribe to HMRC’s Employer Bulletin and assign someone on your team to follow regulation updates.
