We did a VAT return for a client, made a mistake on it and it was submitted online before it was noticed. We rang the VAT man and they said that if we send a letter detailing what happened and the amended figures it'll be sorted out and they will pay the amended figure. This was sent off but the client had a direct debit for the original amount go out this morning and he has now hit the roof and wants the difference back.
What will the VAT man do and how soon will he do it? Will a cheque for the difference be sent to the client? Will they hold it on account for next quarter and take less via direct debit next qtr? The client wants it back this afternoon (which I know is not going to happen) but what sort of a time scale are we talking, based on other peoples experiences?
