After the lockdown in March the client's business was on the rocks so we de-registered for VAT. Just before Christmas he picked up a large contract out of the blue, which necessitated re-registering.Although we have the new VAT certificate and number it still shows the old number on the HMRC website and the fact we de-registered but states that VAT returns are now due in 2021
What do we have to change the VAT number on the site or don't we have to bother ???
