Last year my dh got a pay rise which took him just over the threshold for child benefit. I said he needed to register for self assessment for tax, so I could still claim it. He's earning just over the 50k cap, I know it's now just gone up.
Anyway, since filling in the self assessment, he's had 3 different tax bills, one for tax year 2022-23, which he didn't even earn over the threshold, they've just found missing tax, but he's a PAYE. Plus a bill for 2023-24, and an amount for overdue, because he missed the deadline, because he signed up early, not realising, he'd then have to file his tax assessment for the year 2022-23, when he wasn't actually earning over the threshold. He got his pay rise at the end of that tax year.
I hope this is making sense.
So now we're owing HMRC over £1500
Is there anything we can do? We only wanted to do the right thing!!
