Will leaving Thailand tomorrow be a problem if my work permit is canceled but my visa is valid?

You didn't enter with ANY work permit <- that doesn't let you IN or let you STAY, that lets you work and has nothing to do with your visa/extension in your passport

NOW if your work permit was cancelled you should have gone to the immigration office and cancelled the extension <- because one of the requirements for you to keep an extension based on employment is that you hold a work permit, so lose that, lose the extension.

You'll certainly get out okay..

I would guess you have an extension of stay good until 29 Jan 2026 w/a re-entry permit

If that's the case when you come back (as long as it's before 29 Jan) and you had a multiple re-entry permit you'd get stamped back in until the 29th of Jan again.

The officers at passport control stamping people in can't tell if you hold a valid work permit or not, they can only see the stamps in your passport

Once you get back you still need to go to the immigration office that issued your extension and cancel it

You need to get a re-entry permit.

If your company hasn't filed anything about your så, you should be fine.

Do you have a re-entry permit in your passport ?

It appears that you were stamped in until the end of your current Non B visa extension of stay with you having a Thai work permit.

Let's see if others have a helpful reply. As it's now after midnight of a new day in Thailand, and you are flying this day.

What is your passport nation ?

If you have ended work in Thailand...I assume that you did not cancel your work permit not have told Thai Immigration that you are no longer employed.

That's a problem for you.

My advice is ... NOT 🚫 LEAVE THAILAND as planned.
