Do I need to submit a 90-day report before leaving Thailand if I'm returning in January?

i have been staying in hotel which is paid until the end of September. I have taken a condo with 12 month lease but I wanted it earlier so I could get it prepared. Will immigration be bothered that I am registered at two addresses overlapping 10 days until end of month. Agent will not budge on registering me later , I kinda understand they want to keep themselves right in law. However will it affect me? I paid a lot for the hotel so don’t want to lose the luxury for 10 days .

Are you currently on an initial 90 day Non-O, a Non-OA or a 12 month Extension of Stay? The Non-O does not require a 90 day report, the other 2 do.

Leaving country no need to do 90 day if left before it was due. Your next 90 day will be due 90 days after you return. You will need to submit your tm30 to your local immigration 24hrs after return.

I trust you have any re-entry permit.

Count your days carefully. Your entry day is day 1. You have to report if you are in Thailand 89 days after that.

They won’t care at the airport when you leave but when you return and are due your next 90 day report an eagle eyed officer may spot that you didn’t report correctly earlier and slap you with a 2,000 baht fine.

If you will be here for 90 days then do your report up to 15 days prior just to CYA.
