Pay backdated vat

We are going to register for vat but accountant is registering us from June 2022. So we need to pay vat from that date? Even though we have not charged our customers vat?

Hi Bethan,
Hi.If your accountant backdates your registration then you will be liable to account for VAT from that date.
You will also be able to reclaim input tax on goods/services from date that and prior to VAT registration subject to the criteria below:
11. Input tax when VAT paid on goods and services received before VAT registration
Thank you.
