90 day reporting online.
We have many posts from people that have tried to do online 90 day reports that have been rejected. Many times the reason for the rejection isn’t clear or even stated.
The 90 day report system takes your request to file online and routes it to your local immigration office to approve or reject. Like many things in Thailand different offices have different policies.
The two main reasons for a rejection are that you are trying to do your first report online since entering Thailand. It doesn’t matter that you’ve been here for 20 years. If you’ve just returned from a trip abroad and are trying to file online it may be rejected as it’s your “first” report since entering.
The second and possibly the main reason is that the address you are using on your report doesn’t match the address that’s on file for your TM30. Many people I see coming in to the office state that “they’ve been in the same address for X years” so it shouldn’t be an issue. But forget that they stayed in a hotel (or even a hospital) 2 months ago in Samui or Bangkok or Nakon Si Nowhere. The hotel/hospital is obliged to file a TM30 for you and therefore updates your registered address to their location.
As stated its office specific, so one office may approve the filing whereas another will reject it. If rejected you can file a new TM30 online and try again. Perhaps you will need to go to your local office to resolve but almost certainly they will tell you the same thing. The address on file for the TM30 isn’t the same as the address used for the 90 day report.
TLDR : Answer Summary
When filing a 90-day report online in Thailand, rejections can occur for several reasons. The primary reasons include attempting to file your first report online after returning to Thailand, or discrepancies between the address used in the report and the address on your TM30 form. It's important to remember that different immigration offices may have varying policies, affecting approval rates. Other noted causes for rejection include filing outside the designated window of 15 to 8 days before the due date.
