Siam Advice FirmTax Analysis

With 72 hours to go, most foreign investors will be using the RD Smart Tax portal. Here is what to expect as you click through the screens.

 

The 4 Main Stages of Filing

  1. Identity Verification: After logging in, you will verify your address and personal status (Single, Married, Divorced).
  2. Income Entry: You will select your income types (Salary is Section 40(1)). If your employer has pre-filled this, verify the numbers against your physical Form 50 bis.
  3. Deductions & Allowances: This is where you enter your insurance, investments (RMF/SSF), and charitable donations. Be prepared to input Tax IDs for each provider.
  4. Summary & Payment: The final screen shows your Net Liability. If you owe more, it will provide a QR code or payment options. If you are getting a refund, it will ask for your bank details.

 

The "Save and Continue" Button

You don't have to finish everything in one sitting. You can Save Draft at any stage. This is useful if you realize you are missing one specific receipt while mid-process.

 

Confirmation Received

Always download the Confirmation Receipt (PDF) at the very end. This is your only legal proof that you fulfilled your March 31 obligation.
