Do I have to pay my self assessment bill in one go?

I have 3k to pay by jan 31st. Can I pay a part of it today and each month or does it have to be in one go?

pay a bit at time if you want .HMRC dont care so long as you pay on time.

As old git says, as long as it's all paid by the due date not an issue. If you look at your tax account you'll see the money paid will be there saying it's been paid as

"Your payments
£xxx.xx in credit

This will pay your tax bill of £3,000.00 on the 31 January 2019."

Or, some thing like that depending on how much you pay.
