Does getting an O visa extension reset my 90-day reporting date in Thailand?

Generally no but check if they gave you a new report receipt. I just did my report yesterday and I get my new extension stamp on Friday so the extension application did not change my 90 day reporting schedule.

Here is a 100% fool proof way to tell if you got your 90 day reporting reset when you get a new extension

You ASK yourself

𝗪𝗵𝗲𝗻 𝗜 𝗴𝗼𝘁 𝗺𝘆 𝘆𝗲𝗮𝗿 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻 𝗶𝗻𝗸𝗲𝗱 𝗶𝗻 𝗱𝗶𝗱 𝘁𝗵𝗲𝘆 𝗴𝗶𝘃𝗲 𝗺𝗲 𝗮 𝗡𝗘𝗪 𝟵𝟬 𝗱𝗮𝘆 𝗿𝗲𝗽𝗼𝗿𝘁 𝗿𝗲𝗰𝗲𝗶𝗽𝘁 𝗽𝗮𝗽𝗲𝗿 𝘄𝗶𝘁𝗵 𝗮 𝗻𝗲𝘄 𝗱𝘂𝗲 𝗱𝗮𝘁𝗲?

IF that answer is YES and you DO have a new receipt then they DID re-set your 90 day reporting and you report on the date on the new paper

Whereas

IF that answer is NO and you DON'T have a new receipt they DID NOT re-set your 90 day reporting and you report on the date of the receipt you have now

Did they staple a new 90 day receipt in your passport?
