Will I be fined for doing my 90-day reporting after the due date in Thailand?

and I think that the O/P has enough information right now to show up and do her 90 day report 🙂 Thanx one and all for the comments

Why making an appointment just front up after the welcome just say 90 day report, never done online the 5 years I have lived here always front up takes about 10 minutes usually.

When i returned from an overseas trip earlier in the year.. i made sure i noted the revised date for my next 90-day report.. when the date neared i attempted to do it online (about 5 days early) but it was rejected.. so i ended up going in to the immigration office at Central Festival (CM) to do it in person.. upon questioning the officer about my online experience he informed me that if it was the first report after an overseas trip.. then i could only do it online if i submitted it on the actual date it fell due.. and any attempt to file it early or late would be rejected by the system.. so if you are in this situation it may be worth trying to file it online on the actual due date before making a road trip to immigration.. especially if you live a fair distance away from the nearest reporting centre 😉

Don't be late, you will be fined even if only one day late. Be early, report on day 81-90, best early in case need other paper.

Bring everything, including house papers and/or landlord papers (owner I'd, etc), original eVisa, everything. Keep two folders/envelopes, one with papers you think you need, one with everything from first Entry to Thailand. Never know what each immigration person might ask for.

Have photocopies of everything, not all immigration offices will make copies.

Have lots of cash, just in case.

You're lucky, mine is an 8hour round trip by car, at least the small office is pretty fast.

I always register tm30 just prior to doing 90 day report to make sure addresses match up. I have not been rejected in over 2 years.

One other option is to skip 90 day reporting and pay the 2000B fine annually when you get your extension as many do

Not sure which office you are dealing with...but don't see why you'd even need an appointment for 90 day report?

In CNX Immigration we have a drive thru / walk thru window which takes 1-2 minutes...

Online rejections are getting silly now..mine indicated " rejected because the address doesn't match" .. been at the same address for 15 years.

More and more people are getting rejected after returning to the country with the reason; "first report needs to be done in person".

You are allowed to apply in person from two weeks before the due date until one week after the due date without a penalty.

So if you have an appointment on the 7th day after the due date you would be able to file the 90-day report that day and not be fined.

Whether you should slog over there before your appt and wait it out in the queue with the zombie horde is something only you can decide.
