If you deferred VAT between 20 March and 30 June 2020 and still have payments to make, you will need to pay the deferred VAT in full on or before 31 March 2021.
However, you can opt in to the VAT deferral new payment scheme when it launches in 2021 or you can contact HMRC if you need more help to pay.
If you want to opt in to the new payment scheme
You cannot opt in yet. The online opt in process will be available in early 2021. You must opt in yourself, we cannot do this for you.
Instead of paying the full amount by the end of March 2021, you can make up to 11 smaller monthly instalments, interest free. All instalments must be paid by the end of March 2022.
If you opt in to the scheme, you can still have a time to pay arrangement for other HMRC debts and outstanding tax.
