Why renew tax and PRB together
Annual car tax renewal requires a valid PRB as a supporting document. Most owners renew both together so their expiry dates stay aligned year after year. Doing it in one flow also makes it easier to review your voluntary insurance for the same period — fewer separate transactions, fewer reminders to track.
Documents you'll need to renew car tax
Check these before you start so the tax and PRB renewal goes smoothly.
- Car registration book (blue book) or a copy
- Valid PRB document — or renew PRB in the same flow
- Vehicle inspection certificate from a private inspection centre (Tor Ror Or), if your car is over the age threshold
- Owner details and current mailing address for document delivery
- Credit card or another supported payment method
If you renew PRB with Gengmak in the same flow, the system reuses your car details — no need to re-enter.
When does your car need a Tor Ror Or inspection before tax renewal?
The Department of Land Transport requires certain vehicles to be inspected before tax renewal, based on age from first registration.
| Vehicle type | Age threshold for inspection |
|---|---|
| Private passenger car (up to 7 seats / sedan) | Older than 7 years |
| Private passenger vehicle (more than 7 seats / van) | Older than 7 years |
| Private pickup truck | Older than 7 years |
| Motorcycle | Older than 5 years |
Vehicle age is counted from first registration. Inspections are done at private inspection centres (Tor Ror Or) nationwide.
