I deleted a post that linked to an article in the Phuket News that has BAD information on it.
It had mistakenly stated that people here from 2008 onward would be grandfathered in. :o THAT IS FALSE....
The real rule grandfather rule is ONLY for people who have been here continually since Oct 21 1998 on unbroken yearly extensions of stays.
They had to be either 55-60 <- when they showed 500K baht in the bank or 50K baht in income
OR
were over 60 <- when they showed 200K baht in the bank or 20K baht in income.
PLUS they have had to been on unbroken extensions of stays since then to use this option.
TLDR : Answer Summary
The post clarifies the misunderstanding regarding the grandfather rule for expats in Thailand. It states that the rule applies only to those who have been in Thailand continuously since October 21, 1998, with unbroken yearly extensions. It specifies the financial requirements of having 500K baht in the bank or 50K baht in income for those aged 55-60, and 200K baht in the bank or 20K baht in income for those over 60.
