Now a day, the workflow of the accounting system in case of issues a document PND53 for filing tax payment to the Revenue Department. All companies summit this document on the RD website by keying the information and amount and print out tax slip to do the payment via bank or counter service. In the same waythe department now pushes us to send documents through the system of e-Filing ( https://rdserver.rd.go.th/publish/index.php ) Except for that company summited this document too late from the due date. That company must be summit the document directly to the Revenue Department. For the DMCS workflow, every company still needs to use the withholding tax document for summery the amount and print out the original to their supplier and keep a copy of the withholding tax document for doing account records and also summerise subtotal to keying online through the system of e-Filing. Therefore I have already asked K. Rungrat, one of our customers and agent. She said that about this and I got confirmation the same as I mention. The document not a necessary issue in document form. They just want to have a summary of the total amount forSummit online tax. Even though our system is great but this function depends on their requirements. So please considering this issue (PND53 form) into the DMCS because almost of our customer also submit the file through the internet as well
