This agreement exempts any individual residing in Thailand and the country where Thailand has signed the agreement with from paying income taxes on both countries. To clarify, an individual can pay income taxes in the country where the individual is currently residing. The DTA has several purposes regarding income tax:
Prevent double taxation for reducing financial burdens among individuals.
Avoid conflicts on taxing rights ensuring income is taxed once or at a reduced rate.
Ensure fair treatment on taxation from discrimination.
Prevent tax evasion and fraud by sharing information with the contractual party.
Promote economic activity in stimulating cross-border transactions and investments between the treaty countries.
As of 9th October 2023, Thailand has signed the DTA with 61 countries. Nevertheless, the individual may be subject to double taxation in Thailand and the country where Thailand is not a contractual party to the DTA.”
I don’t know what their service rates are; however, it would be a lot cheaper than CA robbing you in taxes. Nice people and they’ve been in business a long time.
