Does renewing a non-B visa count as a 90-day report in Thailand?

This comes up quite a lot and happens to more people than you would imagine

Here is a foolproof way to know when you got your extension if they reset your 90 day reporting date

When you get your extension inked in ask yourself; did they give you a new 90 day report receipt with your next report date on it?

If that answer is yes and you have a new 90 day report receipt follow it

If that answer is no and you do not have a 90 day report receipt you use the old one or go by your last entry date to thailand.

The above is not a snarky answer and it's meant with all sincerity, you'll get a new 90 day report receipt IF your office resets it when you get an extension.

nope getting a new extension of stay does NOT count for a 90 day report,

If you stamped in to thailand on July 31st your 90 day report was due on Oct 25 and you can report up to a 7 days late so the latest date you could have reported without a fine would have been Nov 1.

After that it doesn't mater if you're 8 days late or 8 months late on it, you pay the 2000baht fine.

No they are separate things.
