Hi I am trying to update our Irish VAT number in account settings , I update save /done but it disappears why is this pls ?

Hi there, Mags. QuickBooks conducts a validation check for VAT numbers. If a number is incorrect or not yet recognized by tax authorities, the system will remove it.

Please make sure that the Irish VAT number is entered correctly, typically in the specified format.

Please let us know if you need any further assistance.
