and also reimburse those people who have already paid in advance.
We all pay in advance - why bother as it'll balance itself out when VAT rate goes back up. We would still get 13 months at a slightly reduced amount.
The invoice date/tax point is what actually determines VAT rate applicable. Were I to still be VAT registered I'd apply 17.5% to all invoices up to 30th Nov and 15% to all invoices from 1st Dec 2008 until 31st Dec 2009. I'm sure that my "friendly" VAT inspector wouldn't argue with that
