90-Day Reporting, Explained Simply

If you stay in Thailand on a long-term basis, you must periodically tell immigration where you live. It sounds bureaucratic — and it is — but it’s simple once you’ve done it once.

What it actually is

The 90-day report is a notification of your current address, made roughly every 90 days of continuous stay. It is not a visa renewal and doesn’t change your permission to stay — it’s just “I still live here, at this address.”

Who has to do it

Broadly, anyone staying long-term on the kind of extension retirees use. The clock is about continuous presence in Thailand, and leaving and re-entering the country restarts the 90-day count from your re-entry date.

How to file it

Usually one of:

• In person at your local immigration office (Jomtien for much of Pattaya)
• By post, sent ahead of the deadline
• Online, where the system is available and working for your case

You can file within a window around the due date: from 15 days before to 7 days after it.

If you’re late

Expect a fine (around 2,000 THB) and a bit of hassle; persistent lapses make other tasks stickier. Set a phone reminder a week before each due date and it never becomes a problem.

A simple habit: photograph your reporting slip each time. The next due date is printed
