Do I need to submit TM47 and TM30 online for my 90-day report in Thailand and bring cash?

To complete your 90-day report in Thailand, you need to file the TM47 (yourself) online, while your landlord will handle the TM30. After completing these forms, print them and take them to the immigration office. It's important to note that the 90-day reporting is free and there's no need to submit anything online. Ensure to bring your completed TM47 and the TM30 receipt for the immigration staff. You do not need to bring cash unless you are making a late report, which incurs a fee of 1900 baht. Also, have your hotel receipt, lease, or housebook ready, as not all immigration offices accept printed TM30 forms.
