What is the last date I can leave Thailand without needing to do a new 90-day reporting if my due date is November 10?

The 7 day grace period is for reporting only, not for leaving

The last day you can leave without reporting is November 9th. On November 10th you'll have been in Thailand for 90 days and whether you leave or not you're still required to report that you were in Thailand for 90 days.

90 days report is "Notification of staying in the Kingdom over 90 days". To notify that the fact you are staying over 90 days continuously, i.e you notify that you are still in Thailand for consecutive 90 days. You have a time window of notification of the fact that you are still in Thailand on the 90th day from 15 days before until 7 days later of said 90th day.

So if you are staying on the date on your receipt for 90 days, you need to do 90 day report.

The new 90 days counting starts again on the day you enter Thailand again or you submit 90 days report.
