Hi I'm on a single entry non o based on a retirement, my next 90 day is 29th September arrived back to bkk on 31st August after a 2 week trip to UK I had a re-entry stamp when I left Thailand, am I correct that instead of reporting the 29th sep it will now be the 28th November, thanks in advance 

Your starting date is August 31, 2025 so that means that 89 days later would be November 28, 2025. 

 

Note you are required to do this in person or via mail. 

if you opt for mail do it 15 days prior to  Nov 28

it will be 89 days from your last entry, you are not on a single entry non imm O visa, you are on an extension or your permission to stay

If anyone needs advice on how to do report from various options, then this site (non gov) is clear and helpful.
