Sorry to sound ignorant, but I filed my first tax return last year. In the past year I've made two payments towards this current tax bill (2021-2022)!
You'd think they'd make it easier to pay the tax bill. But I assume I deduct whatever I have already paid towards my 2021-2022 bill to get the final amount and then pay that? From the calculation at the end it looks like they haven't done that.
Hope it makes sense, any help greatly appreciated
