Self Assessment Noob Help

[SBF]

Hello all,

My Mrs new (ish) job involves her travelling a lot in her car, she receives a car allowance and is paid £0.13 per mile for fuel.

She has submitted a self assessment form to claim the additional tax relief on her mileage, and has had a letter back from HMRC, changing her tax code by the amount claimed (around £1800) for the tax year April 22 to 23.

Does this mean she is not going to receive a rebate, and the £1800 she is owed will be paid to her in reduced tax over the course of this 2022-2023 period?

That’s how I am interpreting the letter. However she says her salary has only changed this year by about £2 per month.

I wasn’t involved in the process, I’m only hearing about it now, as she is was expecting a rebate but has not had one.

I have never had to submit a self assessment myself or claim tax relief from HMRC so I’m next to no help.

Thank you all.

Back of a fag packet calculations then, assuming she's a basic rate taxpayer, she should get £360 back (20% of £1,800). However £2/month is £24 a year.

Have you taken the 1.25% NI increase in April into account? Again using "back of fag packet" if she's on £35k or more then the increase in NI will have offset the increased tax free allowance.

Thanks for your reply Countdown. She’s on circa 38k plus car allowance, I hadn’t considered the NI increase perhaps that is what’s swallowed it.
