I don't know why I have been put on a non cumulative tax code

2 Posts

I'm a supply teacher and have been put on a non cumulative tax code because I started working for another agency in October last year and a previous agency had not closed my account and sent off my P45. I have underpaid apparently but I still don't really understand how. I do not get paid in school holidays so my tax is different from month to month.. I was unemployed for 4 weeks of the summer holidays and did not start work again until mid Sept. Will my tax code return to cumulative tax after April? HMRC have said I can complain but does this mean I will get my payment back?

Have the other agency issued you a P45 now? You can log in to your Personal Tax Account to check what information HMRC holds and if your expected earnings for the year are correct.
Complain about what?
Being on a non cumulative tax code is perfectly normal, lots of reasons why this has happened.
Complaining won't sort your tax out but explaining exactly what has happened during the current tax year will enable people on here to work out if you could have cumulative tax code again in the current tax year. If that is possible then your current employer would make any tax refund due the next time they pay you, you wouldn't have to wait until the summer for HMRC to make any repayment which may be due.
How many companies have you been paid by in the current tax year?
Do you have P45 details from some?
How many companies are you still on the books with?
What is the non cumulative tax code?
