Tax refund from expenses

I phoned HMRC but I'm more confused now than I was before. I put a claim in for uniform, for the past 4 years. I have a letter with my new tax code going forward (great, increased tax free amount of £143) and a cheque for £110.38 for the tax year 2023-2024 (great). Does this cheque cover my claim of the past 4 years? Or just 2023-2024?

Hi,

Normally, if we receive a repayment claim for multiple tax years we will issue a separate calculation for each tax year with a breakdown of how the repayment has been calculated, but one cheque for the total amount. The calculations will generally show the amount overpaid for each tax year with this being carried forward to a future tax year.

Tax relief on job expenses is given at your highest rate of tax, so job expenses of £143 at the basic rate would result in a repayment of £143 x 20% which equals £28.60 approximately overpaid each year. You can see guidance here:

Thank you.
