An ex employer has written to me to say I underpaid tax in 20/21 due to taxable benefits and it was their error so they will make any underpayments and I'm not liable.
I have paid this tax through my tax codes in 22/23 and 23/24.
So my question is what does this mean?
Will I get back what I paid, around £500, or will I be facing another tax code change?
