I have recently started a new PAYE position with a higher salary than my previous job, however my monthly income has been significantly less than what I received in my previous (lower paid) position. I checked how my tax free allowance was calculated and made some changes. So I removed child benefit (which I shouldn't have to do since I am still within the bracket of it being a benefit) and that made a difference. But I'm still receiving less in my salary than when I was in my lower paid position. I have noticed that the tax free allowance includes an amount for a benefit from my previous company, even though I no longer recieve that benefit. I have tried to update it online, but as I did recieve the benefit for around 2 months into this FY it doesn't seem to recognise that it is not a current benefit. Can anyone advise what I should do about that, or anything else I can do so that my new monthly salary better reflects my increased pay? Thank you!
