Unused Employers National Insurance allowances

Yes, John, you'll have to reach out to HRMC to claim unused employee allowances from previous years. Please note that you can only claim unused Employment Allowance from the previous four tax years. Allow me to share further information.  

Claiming unused National Insurance allowances for past years is not available in QBO, as it cannot submit the required Employer Payment Summary (EPS) for such claims.

Thus, I recommend getting in touch with HRMC to inform them you need to claim Employment Allowance for the year using the p32 form:

• Use any unclaimed allowance at the end of the year to pay any tax or National Insurance you owe (including VAT and Corporation Tax if you do not owe anything on your PAYE bill).
• Give you a refund after the end of the tax year if you do not owe anything.

Additionally, I'll add this helpful tool from the HMRC website that guides how to claim employment allowances: How to claim Employment Allowances.

Once you claim the employee allowance, you can now start using your Employment Allowance as soon as you submit your claim.
