CSLM13162 - FAQs: forms questions and answers: my P60 doesn’t show correct SL deductions?
Suggested answer
Your P60 doesn’t include any Student Loan and or Postgraduate loan (PGL) repayments deducted by any previous employer. If you have had more than one employment during the tax year you should use your payslips in addition to your P60 to work out the total.
If you think the total student loan deductions on your P60 have been incorrectly calculated, speak to your employer/payroll department in the first instance as there may be a payroll error.
