Why is the pay on my P60 different from my salary?

A £36,000 annual salary describes £3,000 for an ordinary full month under a twelve-instalment arrangement. Six such months produce £18,000 before any other earnings or pay reductions. The advertised full-year salary is not the expected P60 amount for a half-year job.

Use the payments in the selected 6 April–5 April tax year, not a company financial year or calendar year. Payroll cut-offs, arrears and payments after leaving can place work and cash payments in different periods. Ask which payment dates and adjustments are included.

For a partial month, check the employer’s contractual divisor rather than estimating from annual salary alone. The pro-rata calculator’s part-month explanation shows why different methods produce different gross amounts.

Overtime, commission, bonuses and other taxable earnings can make reported pay higher than the basic salary paid for the covered period. Statutory sick or parental pay can replace normal wages; it is not always an extra amount on top.

Suppose six ordinary months produce £18,000 and a £1,000 taxable bonus is paid in the same tax year. The earnings bridge starts at £19,000, not £18,000. If one month includes lower statutory pay instead of normal wages, use the actual replacement amount in that month rather than adding both.

Keep expenses and benefits under their actual payroll treatment. A reimbursed cost, a taxable benefit and cash wages do not always belong in the same field. Ask payroll how an unfamiliar item was reported instead of assuming every bank deposit is taxable salary.

With a valid salary-sacrifice arrangement you give up contractual cash pay in exchange for a benefit. A pension sacrifice can reduce cash taxable employment pay; it is not simply an ordinary pension deduction after tax.

Arithmetic example: £36,000 cash salary reduced by an agreed £1,800 annual pension sacrifice leaves £34,200 cash pay before other earnings or taxable-benefit adjustments. Compare that revised basis with the payslips, rather than subtracting the same £1,800 again after reading the reported taxable figure.

Other schemes can have taxable benefits as well as reduced salary, so the pension example cannot be applied unchanged to every benefit. Read the salary-sacrifice guide and ask for the actual pay/benefit breakdown.

Under a net pay arrangement, the employee pension contribution is taken before Income Tax is worked out. Under relief at source, the contribution is taken after tax and the provider normally adds basic-rate relief. The same-looking cash deduction can therefore affect the P60 pay figure differently.

Illustrative annual pay bridge, with no other adjustments

Pension method	Cash gross earnings	Own deduction	Employment taxable pay
Net pay	£36,000	£1,800	£34,200
Relief at source	£36,000	£1,800	£36,000

This compares how the recorded pay changes; the two £1,800 deductions are not a statement of equal gross pension funding. Provider top-ups, extra tax relief and contribution bases need their own checks. Use the workplace-pension guide to establish the method.

A current employer’s certificate can show previous-employment amounts as well as this-employment pay. Compare the latter with that employer’s matching year-to-date taxable figure. Do not compare a combined year total with a single employer’s gross-pay column and call the difference an error.

Build one line per actual payment or adjustment: cash earnings, relevant pre-tax pension/sacrifice treatment and any other payroll-tax adjustment. Keep bank net pay in a separate column. A loan repayment, attachment or other post-tax deduction can change the bank deposit without reducing P60 taxable pay.

If payroll made a retrospective correction, ask which tax year it affected and whether a replacement certificate or explanatory letter was issued. Do not remove a difference with a balancing number you cannot identify.

For example: “My contract rate was £36,000, I was paid for these six full months, and I have identified a £1,000 bonus and £900 net-pay pension deduction. Please confirm the employment-specific taxable-pay total and explain any remaining adjustment.” The simple bridge in that example is £18,000 + £1,000 − £900 = £18,100, before any other verified item.

Use the P60 checker for record arithmetic and the multiple-job guide when earlier pay has been carried forward. An unexplained difference is a request for evidence, not proof that a tax refund or wage correction is due.
