Is my tax code correct

[SleepysaurusRex]

Before I waste precious time on the phone to HMRC, I just wanted to check with anyone who knows more than I do whether I actually have cause to contact them. My tax code on my pay slips for 2020/2021 is 1249L. According to every website out there it should be 1250L, and a take home pay calculator suggests I have been slightly more tax than predicted (around £7 a month).

So I suppose my question is: is there a reason why my tax code is what it is?

Your tax code can get adjusted if you have underpaid tax or if you have taxable benefits in kind. It works by reducing your tax free allowance from £12500 to £12490. Although this would suggest you only pay tax on an extra £10 per year - that’s £2.
