What happens at immigration if I list an incorrect departure date after extending a 60-day exemption visa in Thailand?

If one goes to Thailand on the current 60 day exemption visa, and went for just 40 days; but then wished to extend for the full 60 days. Having filled in the Tdac stating a departure date. What would happen at immigration? If one had put 19th of Feb but actually departed 10/11th March?

TLDR : Answer Summary
If you extend your stay on a 60-day exemption visa in Thailand and declare a departure date on the TDAC (Arrival Card), it does not have any binding effect. The departure date is optional on the TDAC and not required. Your stay is governed solely by the stamp in your passport indicating your permitted stay duration. As long as you remain within the 60 days allowed by your visa stamp, no issues should arise with immigration at departure.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

On the departure date use the 60 days if you go home early no problems, but as someone else said it’s only an arrival card

You have to leave before the expiry date of your visa stamp, if in doubt go to an immigration office and check.

In my experience'

My arrival was on Jan 7' 2026

The departure supposedly was on jan 27' 2026' thats the date i put in the TDAC

But then i changed my mind and decided to stay until feb 25, 2026. I didnt go to immigration' didnt go to the embassy.. as an asian' i am allowed to stay until 60 days. Yesterday feb 25, 2026..... nothing happened' no one at the immigration questioned me after the passport control.

Just went on smoothly

The TDAC is an arrival card. If you optionally put in departure details (not required) no one is going to hold you to those. Immigration at your leaving point only care about your “allowed to stay” date. If you’re within that date then no issue.

Pierre-Paul Dubois Nothing, so long as you exit prior to the stamp date in your passport. Departure details on TDAC are not mandatory, no red asterix, so no problem.

The TDAC is an arrival card. It has nothing to do with when you leave, and that's not even a required field. You can leave it blank. But no one is tracking you based on TDAC. You can stay until the stamp in your passport, that's all that matters.
