Payments can be made via the GIB website, Digital Tax Office, GIB mobile app, partner banks, PTT branches, or any tax office.
Legal Consequences Failure to file within the statutory period results in a procedural penalty.
Late payment triggers a tax penalty and interest.
To qualify for the tax credit, the return for the current year and the previous two years must have been filed on time.
Timely filing and payment ensure smooth compliance with tax obligations.
