Hi,
The time of supply rules determine when a taxable supply is being made and this would have to be considered when determining when the company should have become VAT registered. Please see below:
Time of supply (tax point) rules
The requirement to register for VAT is based upon the taxable supplies made in a rolling 12 month period. Please see the guidance here:
Working out whether you need to register
If the registration was required prior to the date when you have registered for VAT in 2024 then you would need to write in to request the date of registration be changed. This would need to be done by writing to the following address:
BT VAT,
HMRC,
BX9 1WR
Thank you.
