I’ve missed mileage from 22/23 Tax Return

drfclee

Hi, I submitted my 22/23 tax return but was recently told that as I had only been claiming business mileage at cost that I could claim the different between 45p and the cost on my tax return.

My Q is; can I resubmit my 22/23 return or can I add the mileage detail to my 23/24 return? I don’t want to miss out on any possible money.

I’m employed and paid by PAYE but went over 50k so tax office asked me to submit for going over child benefit theshold. Ended up with a £1000 tax bill. Due to only getting actual fuel costs back from work, I have missed out on £1400 (mostly from 22/23 period). Since July I’ve been getting the 45/25p which is way better.

I think you might have misunderstood something somewhere along the line.

You have until 31 January 2025 to amend your 2022-23 Self Assessment return.  You wouldn't include something relating to 2022-23 on your 2023-24 return.

Also, you cannot claim the difference in mileage from HMRC.

You can claim tax relief on the difference.

For example say you did 5600 business miles and were paid 20p/mile not 45p/mile. 

5600 x 25p = £1,400.  The £1,400 reduces the amount of employment income you will pay tax on (and is likely to reduce the High Income Child Benefit Charge as well).  The £1,400 might save you between £280 and £560 in income tax depending on how much higher rate tax you are liable to.

Ah right, that’s good to know. I’m assuming I just log back in and make the amendment. Tax returns are very new to me so very unsure of them. I’m happy even if it is just the tax part that can be claimed. Anything is better than nothing.

appreciate your advice on this

Yes, you can just make the amendment online.  

The added bonus in your situation is that it should also reduce the HICBC (assuming your adjusted net income was between £50k & £60k).
