he has already said he will be making remittances. I can see no comment stating that the “Thai tax dept will be able to link your credit/debit card to your passport”. What comments are you reading?
1) After 180 days in the Kingdom in a calendar year you become automatically Thai tax resident and subject to Thai tax law. Thailand charges every tax resident personal income tax (PIT) on a sliding scale from 0-35%. PIT is charged only against assessable income therefore not all funds remitted may attract a tax liability.
2) It is irrelevant that you don’t have a Thai bank account into which you remit funds. The Revenue Department classifies a remittance as “bringing into” Thailand either electronically or physically. If you move funds into Thailand via apps it doesn’t make any difference the Revenue Dept will still assess it for a tax liability.
3) You need to file taxes once a year and ONLY if you qualify. You can be tax resident and never have a tax filing requirement due to the funds you bring not being assessable income.
4) You will need to get a taxpayer ID within 60 days of remitting assessable income.
You will need to file taxes if you remit above certain minimum thresholds (60-220k baht depending). Obtaining a TIN is a free service at any Revenue Office. Filing a tax return is a free service, filing online is a free service.
5) If you come with a DTV and enter Thailand in July then you have five months to enjoy tax free remittances on ANY funds as you would not be tax resident in that year.
Anonymous participant the ED visa and the DTV are two separate animals, each with their own rules and requirements, don’t confuse the two. You cannot work on an ED visa but you can work online for non Thai customers with a DTV.
