By way of introduction, I work in the indirect tax team based in London and responsible for VAT compliance reporting for Expedia Thailand.
We have received the attached tax invoices from CAT Telecom and TOT. I understand that you are familiar with these vendors.
Following a review by our external advisors, it seems that the tax invoices have been incorrectly marked which has been detailed on the invoices.
Can you please reach out to the vendors and have these invoices corrected ?
Once corrected, can you kindly send the original hard copy to our local office manager (Jaruwon) who is in copy.
Without a valid tax invoice, we will be unable to obtain a VAT deduction on our monthly VAT return reporting.
We need these revised invoices before 8th February if possible.
