DLT Vehicle Tax is a free Android app developed by the Department of Land Transport Thailand. This app is designed for individuals who own private cars with no more than 7 seats (Type 1), private cars with more than 7 seats (Type 2), personal pickup trucks (Type 3), and personal motorcycles (Type 12) to pay their annual vehicle taxes.

The app allows users to check if their vehicles are eligible for tax payment, view their tax amount and additional fees (if any), and make payments through various QR payment systems of different banks. Users can also receive a temporary tax payment certificate valid for 15 days and request to receive their actual tax payment certificate with a tax payment stamp via postal mail. In the future, users will also be able to print their tax payment stamp through the DLT Kiosk system.
