We have a contractor who sent an invoice for services supplied in November 2018. The invoice did not include VAT, and did not show any relevant VAT registration number.
We have just received a letter stating that there was an error on the original invoice and they should have been claiming VAT and requesting us to pay the VAT not included.
Now this sounds rather dodgy to me and I don’t believe we have any obligation to pay this? But, I’m not certain. Due to the age of this invoice, it also falls into last years accounting period.
Can anyone kindly shed some light on the laws surrounding this please and give advice on how to proceed? It’s certainly nothing I have encountered before!
Many thanks in advance!
