The VAT deferral new payment scheme is open for all businesses who deferred paying VAT due between 20 March and 30 June 2020 and were unable to pay in full by 31 March 2021.
If you apply to spread your payments between 20 May and 21 June you can pay in eight instalments.
21 June is the deadline for you to join this scheme.
You may be charged a 5% penalty and/or interest if you do not sign up to the VAT deferral scheme by the deadline of 21 June, or pay in full by 30 June, or get in touch with HMRC to make an alternative arrangement to pay by 30 June 2021.
