PND 1 must be filed online
Since 2567 the Revenue Department has required employers to file PND 1 electronically, so this month's last day is 16 November. Paper is allowed only when electronic filing is truly impossible, with a letter to the Director-General explaining why
Social security: the 15th is a Sunday
We have not seen a Social Security Office notice moving the date, so we suggest sending by Friday 13 November. If you send online, check any extension at sso.go.th before waiting for the last day
Why online filing gets more time
The Ministry of Finance gives 8 extra days when you file and pay through the Revenue Department e-Filing system, valid until 31 January 2570. So P.P.30 online is due on the 23rd, and PND forms online on the 15th, which is a Sunday this month and moves to the 16th
How to do it in the app
In GORINY, the P.P.30 page and the withholding tax page total October from the sales documents, purchase bills and expenses you recorded, and build the files for filing. PND 1 comes from approved payroll periods. Always check the figures against the real documents before filing
