You can set up a payment plan online to spread the cost of your latest Self Assessment bill if:
- you owe £30,000 or less
- you do not have any other payment plans or debts with HMRC
- your tax returns are up to date
- it’s less than 60 days after the payment deadline
You do not need to contact HMRC if you set up a payment plan.
Call the Self Assessment helpline if you’re not eligible for a payment plan or cannot use the online service.
