For those who filed tax forms Por Ngor Dor 90/91 for the 2025 tax year but still see the status "Form Analysis/Tax Refund Review" pending for a long time and are starting to worry, don’t panic. The Revenue Department recently clarified that the refund process is proceeding normally. This year, however, there has been a large volume of filings submitted simultaneously, and officials are working at full capacity to process them.
While waiting for officials to review your filing, let’s check whether there is any "sticking point" you might have overlooked that is delaying your refund. Thairath Money summarizes the common causes and offers tips to "follow up" and speed up receiving your refund.
1. Incomplete tax filing...
If the information you submitted does not match the Revenue Department’s database—for example, income or deductions—it is normal for officials to conduct additional verification to ensure accuracy. Sometimes this occurs due to filing the wrong form type or incomplete data entry. You need to correct these errors as soon as possible because some cases allow cancellation or require filing an additional form (especially for online submissions), such as:
- For forms with no tax due or refund requests, if you have not printed the form or receipt, you can cancel the filing on the day of submission (no later than midnight) and then resubmit with corrected information.
- For forms where tax has already been paid and cancellation is not possible, you must submit an additional form with all the updated information.
2. Missing or unclear documents
Many people nowadays upload photos of documents to the Revenue Department’s system. However, if the images are unclear or incomplete—such as withholding tax certificates (Por Ngor Dor 50) or fund purchase certificates for SSF/RMF funds—you should check the system again to ensure all required documents are uploaded clearly and completely.
3. Waiting too long to submit additional documents requested by the Revenue Department
Some taxpayers file their returns but do not check the Revenue Department’s website for days or weeks afterward. When officials request additional documents through the system during the "form analysis" stage, the refund process cannot proceed until the requested documents are submitted, causing the status to remain stuck.
Therefore, you should regularly check the system to see if officials have requested any additional documents, so the refund process can continue promptly.
To receive your refund as quickly as possible (some get refunds within 3-7 days), we recommend these four steps.
1. Check your status via My Tax Account
You can visitthe Revenue Department website,click on the My Tax Account menu, and log in using your RD ID by entering your user ID and Laser ID password from your ID card, or by using Digital ID (the Pao Tang app can also be used for verification). Then select the section to track refund status and submit documents.
Check frequently so you don’t waste time. If the Revenue Department’s processing is slow, you can call the local Revenue office number listed on the personal income tax filing status page for direct inquiries.
2. Make sure your "refund receipt" information is clear There are two options:
1) PromptPay for Thai nationals who have registered PromptPay linked to their ID card number and bank account (you must specify that you want the refund via PromptPay).
2) Refund via branches of Krungthai Bank and the Bank for Agriculture and Agricultural Cooperatives (BAAC). The Revenue Department will issue a tax refund notification letter (Form Kor 21) as evidence to collect the refund at these bank branches.
3. Upload documents immediately (files must be precise)
If the system requests additional documents, promptly scan or take clear photos to upload via the website. Online submissions are much faster than mailing documents.
Importantly, within 1-2 days after uploading, revisit the "Requested Additional Documents" page to ensure the file status shows a green check mark, which means the document is complete and has been entered into the Revenue Department’s database.
4. Hotline 1161 or "Local Revenue Office"
If the status remains unchanged for more than 15 days after submitting complete documents, try calling the RD Call Center at 1161 or find the phone number of your local Revenue Office by your tax filing district to speak directly with the case officer. Sometimes the delay is just waiting for final approval.
