If you take an internal flight within Thailand do you still need to fill in the TDAC when you arrive at your new destination, technically you have not left Thailand so you can't be arriving as you haven't actually left.

TLDR : Answer Summary
No, you do not need to complete the TDAC (Thailand Declaration Form) when taking an internal flight within Thailand, as you are already in the country.
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.

look Todd, Thailand is constantly changing procedures. This person is doing their best to comply! I’m married to a Thai, from the US. Think again if you don’t think rules here or anywhere can be confusing for anyone at any level! I would apologize if I were you, your arrogance is showing.

@Edna ******
look Edna you absolutely daft poster, you are new and don't understand. If you think thailand is 'constantly changing procedures' you have no clue about how other nations work. None whatsoever. Sort yourself out. This one is very, very simple. And your stupidity is glaring.
