As you may already have heard VAT payments due between 20 March and 30 June 2020 can be deferred due to Covid-19. But you still need to submit your VAT return on time.
You do not need to advise HMRC that you are deferring your payment, non-payment is advise enough. Remember to cancel any Direct Debit you have with HMRC unless you do want to make your payment.
If you choose to defer your VAT payment, as a result of Covid-19, you must pay the VAT due before 31 March 2021.
