Which VAT Rate?

[milly143]

We issed an invoice last year for some work carried out. This was invoiced at 17.5% VAT. However I have been told that the amount on the PO we received (which is what we invoiced out) was wrong, so I need to do a partial credit for the additional amount. However I'm confusing myself over which VAT rate I should use. Should I use 17.5% as this was the amount used in the original invoice or should I use the current 20% rate?

17.5 as your crediting the org invoice

[ummmm]

I've always been taught that you by date of invoice.

I agree with mccfluff, 17.5% as that was the % at the date of invoice.

Sorry forgot to say thanks. I used the old rate and they haven't queried it so it seems you were right. Thank you!
