HMRC have fined me 100 pound for not filling out a self assessment form. I'm employed not self employed and once a year I use to fill out a mileage rebate form annually because I was driving to a temporary place of work.
My circumstances have now changed and I drive an electric car and didn't claim for the mileage rebate this year.
Is this something I can argue ? Or, despite being a fully PAYE employee do I need to fill out a self assessment form annually ?
Many thanks
Lewis
