HM Revenue and Customs (HMRC) will take 'enforcement action' to get the money - you may be able to avoid this if you contact them.
There are a number of enforcement actions HMRC can take to get the tax you owe. They can:
- collect what you owe through your earnings or pension
- ask debt collection agencies to collect the money
- take you to court
- make you bankrupt or close down your business
If you don't pay your tax on time, you'll probably have to pay interest on the outstanding amount. You may also have to pay a penalty or surcharge.
Avoid enforcement action
Contact HMRC as soon as you can - you may be able to either:
- get more time to pay
- pay in instalments
You must contact HMRC if you disagree with a tax decision, eg the amount of tax you're being asked to pay.
