Anyone an expert in tax stuff?
My other half got a demand from HMRC in the post yesterday, saying he's underpaid income tax for the FY 22/23 to the tune of 1k.
We absolutely cannot afford to pay it back in one lump sum like they're asking.
He switched jobs part-way through the financial year (September), and by the looks of it from the breakdown they sent, his new job started his tax free allowance from scratch and didn't tax him until he earnt past the allowance, but obviously he'd already earnt 11k earlier in the year so this shouldn't have happened.
He doesn't have payslips as he got them electronically and never saved them, and as he left that job in May this year, he no longer has access to the system to download them again to check what actually came out.
If they did put him on the wrong tax code, do we still have to pay? I know he should have been more observant but you kind of expect payroll to get this sort of thing right.
I'm just really worrying and don't know what to do
