Understand Your Payslip Deductions

Your payslip has gross pay at the top and a smaller number at the bottom, with a row of deductions in between that you have never properly understood. This explains every standard UK deduction: PAYE and your tax code, National Insurance, pension, student loan. It also tells you whether the amounts look right for your situation.

<context>
You have received a payslip and do not fully understand what each deduction means or whether the amounts look correct. Your gross pay is approximately {GROSS_PAY}. You are [employed full-time / part-time / on a zero-hours contract] and [have / have not] received a P60 or P45 before.

3. Pension: auto-enrolment, the employer contribution you may be leaving on the table
4. Any other common deductions: student loan repayments, salary sacrifice, attachment of earnings
5. How to spot a likely error: the two numbers most worth checking
