Change of visa and 90 days reporting

[gearbox]

 

I arrived in Thailand mid January and since I was nearing 90 days in the country I went to report in the Samui immigration office.  The IO told me that I don't need 90 days report as I changed my visa from TR to Non-O (retirement) mid March, and that shifted my 90 days reporting to mid June. I insisted that I've been in the country 90 days and need to report, she insisted that I don't have to. Is it true that change of visa resets the 90 days for reporting from the day the new visa is issued?

When you applied for the non-o visa you got a new entry stamp that allowed you to stay until the 90 days ends. That new entry reset the 90 day report count to zero.

When you apply for a extension of stay it will also reset it to zero again.
