How this is calculated
This tool applies the 2026/27 income tax bands, a £12,570 personal allowance, 20% basic rate to £37,700 of taxable income, 40% higher rate and 45% additional rate above £125,140, to the salary you enter after deducting relief-at-source pension contributions. Employee National Insurance is calculated at 8% between the £12,570 primary threshold and £50,270 upper earnings limit, then 2% above that, matching the figures HMRC expects to see reconciled on a P60.
The result is an estimate of the four key P60 boxes: total pay, total tax deducted, employee NI, and any student loan repayments, so you can compare them against the document your employer actually issues.
What a P60 is used for
A P60 summarises your total pay and deductions for the tax year from the single employer you worked for on 5 April. It is commonly requested by mortgage lenders, letting agents and when applying for tax credits or claiming back overpaid tax, so accuracy matters. Directors of their own limited company should keep P60s carefully, as they are often the only formal proof of PAYE income for lending purposes.
If you changed employer during the year, you should have a P45 from the earlier job and a P60 only from your employer at 5 April, so the P60 figures will not represent your full-year income if you switched jobs.
Common P60 discrepancies to check
Mismatches usually stem from mid-year tax code changes, unprocessed benefit-in-kind adjustments, or statutory payments such as SMP or SSP being taxed differently to ordinary salary. If your estimate here differs significantly from your actual P60, check your final payslip of the year for a running total, as this should match the P60 exactly, and query anything else with your payroll provider.
What this means for your company
Treat the result as a planning figure for the 2026/27 tax year. If it changes what you were about to do, take a director's salary, a dividend, a large asset purchase or a filing decision, check it against your own accounts first. We can review the position with you and confirm the tax treatment before you commit.
Frequently asked questions
When should I receive my P60?
By law your employer must give you a P60 by 31 May following the end of the tax year on 5 April, either on paper or electronically.
What if I had two jobs during the year?
You only get a P60 from the employer you worked for on 5 April. Income from a job you left earlier in the year appears on the P45 from that employer, not on the P60.
Can I use a P60 instead of a tax return?
A P60 supports a Self Assessment return but does not replace it if you need to file one, for example because you have dividend income, rental income or are a higher earner with additional reporting obligations.
Why does my P60 not match my last payslip exactly?
It usually does match the final cumulative payslip of the tax year. If it does not, this can indicate a late adjustment, correction, or an error worth raising with payroll before you rely on the figures elsewhere.
