90-Day Reporting Still Bites in 2026 — Here's the Calendar Discipline Long-Stay Holders Need
In short
If you hold a **long-stay extension** (retirement, marriage, education, some business categories), Thailand's **90-day reporting** obligation still applies in 2026 — online where available, in person where not. Missed cycles stack up and surface at your next extension.
What's changing
Immigration Bureau practice through 2026 continues to require eligible long-stay holders to **report their address every 90 days**, either via approved online channels, by post, or in person at Immigration or designated points. With **THIM** rolling out for broader digital services, reporting habits may shift — but until your visa class is fully covered in-app, treat **Immigration's published channels** as authoritative. A missed report rarely triggers immediate deportation; it **does** create extension friction, fines, and credibility problems when your file is already under tighter scrutiny (as in Chiang Mai and other enforcement hotspots).
Who is affected
**Retirement and marriage visa holders** — highest volume of 90-day cycles; set calendar reminders from first extension. **DTV holders** — different reporting rules apply; don't assume retirement-style 90-day applies without checking your stamp class. **Landlords and agents** — TM30 is separate from your personal 90-day obligation; both must be clean. **Travellers who exit and re-enter** — re-entry may reset the clock; track from last entry stamp.
What you should do
Unsure if you're due? Our **compliance check** reviews your stamp class, last report date, and next deadline — especially before an extension window.
