How does 90-day reporting work and what happens if I miss it?

Anyone staying in Thailand for more than 90 consecutive days must report their current residential address to Immigration every 90 days. This applies to most long-term visa holders, including work, marriage, and retirement visas. LTR Visa holders are only required to report once a year. Missing the deadline may result in a fine and can complicate future immigration applications.

What We See In Practice

My visa is valid for a year, so why do I have to report every 90 days?

WHAT CLIENTS ASK US

Many people confuse 90-day reporting with a visa extension, but they are two completely separate requirements. Reporting every 90 days does not renew your visa or extend your permission to stay. It is simply a requirement to confirm your current residential address with Immigration while you remain in Thailand. Missing a report will not automatically cancel your visa, but it can result in a fine and may cause delays or complications the next time you deal with Immigration.

The 90-day reporting period starts from the day you enter Thailand and only applies if you remain in the country continuously for more than 90 days. You can usually submit the report in person, appoint someone to do it on your behalf, send it by registered mail, or complete it online if you meet the eligibility requirements. If you leave Thailand before the 90 days are up, the reporting period resets and starts again from the date you re-enter.

If you miss a 90-day report, it is best to submit it as soon as you can rather than waiting until your next visit to Immigration. A late report will usually result in a THB 2,000 fine. Additionally, failing to keep your reports up to date can cause delays in the renewal of your visa, as you may not be able to proceed with the renewal until your reporting is current.
