Payslip check: is your pay right?
Photo your payslip. In about 30 seconds TradeCard reads it and checks the tax, National Insurance and holiday pay against HMRC's rates for this tax year. It's free, there's no success fee, and you don't need an account to see the result.
What we check
Tax
Your tax code and the tax taken this period, including emergency and week 1 / month 1 codes that take too much.
National Insurance
The employee rate on this week's or month's pay. For 2026-27 that's 8% between £242 and £967 a week and 2% above.
Holiday pay, pension and the rest
Every deduction shown, and flagged if it doesn't add up to the net pay on the slip.
Questions people ask
Is it really free?
Yes. The payslip check is free and always will be. We never take a percentage of anything we find.
What happens if it's wrong?
You get the figures, how we worked them out, and the words to send to your agency or employer. Most underpayments are fixed on the next payslip once they're pointed out.
What do you do with my payslip?
We read it to run the check. Only you see the result. If you don't keep it, it's deleted. Your National Insurance number and other identifiers are encrypted, and we never sell your data.
Is this advice?
No. It's a check against HMRC's published rates and rules. For a dispute, ACAS, a union or an adviser can act for you.
