I usually do 90-days online and find it actually rather efficient - including the reminder 2 weeks in advance. Long time since I travelled, but recently did a short trip outside TH.

 

Now I have the online reminder, as if I had not left and returned.

 

Will they be happy with me just doing a report again online, or will that get me into trouble? Do I have to tell them I have restarted the 90-day count and go to office with TM47 etc? 

You should do it in person.

New due date starts clock as entry date is day 1

 

Having said that you could play dumb and do the report online and see his it goes. 

 

Very similar situation in another thread and the online was rejected

When was reentry from your recent trip

IF you wait until your new 90 day report is due <- 89 days from the date you stamped back in, and you try to do it online there's a high chance you'll get rejected with this reason on the email 

 

BUT 
you're out nothing by trying to apply from the email (which is just an automatic one sent out based on your previous 90 day report date and which is not tied in to the exit/entry system) 
I mean worst that would happen is you get rejected and then wait until your REAL 90 days would be due and go apply in person then 😛

There's been another discussion recently where someone is reported as doing exactly that and it was approved.  I've recently done it while still out of the country and was approved, so chances are good and it appears you get to remain in the online system without any hiccups.

I'm gunna give that a shot also. 

For my next online report window (Dec) I will be out of Thailand. 

Plan to do the online report when the reminder email comes. 

 

I have been out and back a few times since my last extension.' I was told that I must go in person to do my next 90 day....or...do it by mail in.

I have everything ready to do the mail in 10 days from now...15 days before due.

IF I try on line first....how long does it take to know to know if they accept or not?  

If one or two days......I will try on line first...if more than 2 days, I will mail in.

 

I have done 90 days on line many times before and it always worked, but I forgot how long it took to know if ok or not.

Don't like the plan. 

You state that you have prepared for mail and it's ready to go. 

Do that as soon as window opens. 

15 days prior. 

My recent online took 3 days to approve. I deal with CW. 

 

BTW: I once did both. Mail and online. 

They do not derail each other. 

At that time mail reply took weeks. 

Anyway my online was approved and when the report via mail eventually arrived it had hand written "already reported"

I figure if it's wrong, better to get knuckles rapped than - in the worst-case scenario - get done for overstay! I will do it and report back.

Overstay is not related to 90 reporting. 

Fine for late report can be 2000b

Corrected. I thought it was 2000 per day. Either way, I don't want to pay them.

90-day report on line is hit and miss, last time it was rejected, tried again..approved

Normally one day for me.

I don't find a problem as long as you follow their rule. You must apply between 15 and 8 days (from memory) before the 90th, and you can't do online the first one after returning to TH, or after a new extension.

At other times, it has never let me down, with the reminder about two weeks ahead of time very reliable and no need to fill in the details every time - as indeed it damn well should be, it's not rocket surgery, is it?

But Thailand is after all the hub of failed websites, so perhaps it is brain science to local IT ("Incompetent Thais"?)
