From quoted on request + 7% VAT â fixed quote before we start.
How long does it take?
30â60 at BOI once documents are complete.
How does the Thailand-Japan DTT actually reduce my tax?
We obtain the Certificate of Residence from the Revenue Department, then you file it with the Japan tax authority to credit the Thai tax already paid â up to 100% of the overlap.
Can this be done while I'm overseas?
Yes â sign a POA + courier documents via DHL. We file and return the receipts.
