Do I need to do a TM30 notification when returning to Thailand on a married visa?

Your wife can do that alone to avoid paying 1.600 the. You don't need to join

When you leave the 90 day count down clock stops and your NEXT 90 day report will be due 89 days after you stamp back in to thailand, <- meaning the current receipt you have telling you when your 90 day report is due is no good 😉 .

AND

Most immigration offices DO require you file a new TM30 when you come back from abroad, even if you're returning to your primary address.

So when you come back go file one <- Keep in mind filing a TM30 has nothing to do with your 90 day reporting, they are completely different things.
