Stay legal: compliance habits for long-stay holders
Thailand is welcoming when your paperwork matches your behaviour. These obligations apply across most long-stay categories. Privilege and some LTR tiers simplify reporting, but they do not remove TDAC or overstay rules.
TDAC every entry
Complete Thailand Digital Arrival Card within 72 hours of landing at air, land, and sea checkpoints, including Elite, LTR, and retirement visa holders returning from short trips abroad.
TM30 address registration
Hotels usually file TM30 for you. In apartments and condos, the owner or juristic person must report your address within 24 hours. Missing TM30 blocks extensions.
90-day reporting
Many long-stay visa holders must notify immigration every 90 days online or in person unless their tier uses annual reporting (some Elite and LTR members).
Overstay penalties
Overstay fines run 500 THB per day up to a 20,000 THB cap. Even one day creates an immigration record and can affect future visa applications.
