The owner or agent (realtor) of your condo should file a TM30 every time when you come back to Thailand. Explain your situation and offer some tip for their extra service every month, 1-2k baht.
Johnny Doerthy I believe I made a mistake when mentioning the warehouse. To have a warehouse in a particular country, you need business registration in that country. However, if you have a supplier operating on a dropshipping model, it’s not necessary to have business registration in that country.
The main point is that if you accept payments in Thailand (as a business), you need to register a business there. If you accept payments in another country, pay taxes there, and operate as an international business, registration in Thailand is not required.
I have my warehouse in the country where I manufacture my products, but I had to register a business there. However, when I worked with suppliers, purchasing goods wholesale and shipping them to another country, I didn’t need business registration.
And I could have had orders from the country where I manufacture my products, but I was accepting payments in another country and shipping the goods from my warehouse.
Please do not take my words as advice or recommendations. This is my personal experience.
Theoretically, if your company is registered in another country, not in Thailand, and you’re running an “international business,” it is possible to accept payments in the country where your business is registered. After paying all your taxes, you can take your net income as your salary.
For example, Fashion Nova runs ads in Thailand, makes a sale, accepts the payment, sends the item to the customer from their warehouse (or supplier) in Thailand or another country, and pays taxes in the US - it operates as US company, so it’s legal.
If you’re using a local payment gateway, you will need official Thai business registration.
Anyway, hire a lawyer and get professional consultation. It’s much better than guessing.
