Wrongly taxed

Hi I haven’t paid income tax since May although in my recent payslip that came today one of the deductions was a payment taken away towards income tax, is this worth appealing to HMRC tax office especially with a tax code 1257L and the fact that I’m under the tax threshold…

Did you do a lot of overtime etc for Xmas? If you earned more than 1062 this month, this may have triggered the tax (12750/12=1062). If you did and this was a one off and you are sure you wont go above 12750 in total by 1st April, you could contact HMRC and ask for it to be repaid to you.

Yes I did a lot of overtime

You say your tax code is 1257L -- does it have "M1" or "W1" after the 1257L?

We're now around 9 months into the tax year, so assuming no "M1" or "W1", your cumulative allowance is 9/12ths of 12570 -- so £9427. Your payslip should show your year-to-date earnings. If those exceed £9427, that's why you've paid tax.

If your overall earnings by the end of the tax year (which is April 5th) are below the £12570 allowance, the tax you've paid now will be refunded automatically through your pay.
