One of our accounting clients, a Thai company which is a software and computer dealer, has to pay a German company for software. The software can be installed only once on one computer with a specific period of usage. The transaction is considered permission to use or right to use the software pursuant to the double taxation treaty between Thailand and Germany. The company has a duty to withhold 5% tax from the software price when paying to Germany.
If the company has withheld the tax and paid to the authority higher than the amount required by law, the company has the right to file a claim for a refund within three years from the last day that the company had to submit the tax.
