They have 2 month and 6 month renewals too. Much easier to renew than Thailand 30 day extension and then having to do a border run. I qualify for a 1 year balikbayan privledge when I enter the PH with my Filipino spouse. I also qualify for the PRA military SRRV that has only a 1 time $1500 deposit and $1400 application fee. I also prefer living in Thailand compared to the PH even with the PH having a better longterm visa advantage.
My wife is a Filipino and the Philippines is always an option to live longterm in Asia. Their generous tourist visa can be extended up to 36 months in country before having to leave.
I personally am not worried at all concerning the proposed new tax rules in Thailand. The final language has not been approved and who knows how or when it will affect retirees if at all. My guess this is all a nothing burger for the vast majority of retired expats living in Thailand.
