Contact HM Revenue and Customs (HMRC) as soon as possible if you can’t pay all your tax on time.
You may be able to either:
- get more time to pay
- pay your bill in instalments
You have to pay interest if you pay late. You may avoid penalties by contacting HMRC as soon as possible.
You must contact HMRC if you disagree with a tax decision, eg the amount of tax you’re being asked to pay.
