I am currently seeking work in a school teaching english in Thailand (fully qualified) and therefore, assume I will be applying for a Non-immigrant visa “B” once (if) I get a job offer.

I have my own small graphic design business, currently registered in Ireland. if I would like to carry out work while living in Thailand on this visa, while still working at a school, will I also need to apply for a DTV visa? Should I transfer my business to Thailand instead? I understand that if I will be living here more than 183 days a year, that I will need to pay taxes in Thailand.

tl;dr Can I work on my small business while on a Visa B and teaching in a school?

Here's a few details about the requirement to register for a Tax Identification Number (TIN), which is mandatory for all tax payers in Thailand. Including those who spend more than 180 days per year in the country.

The tax talk starts at 4min 10secs.

So, we are husband and wifey (that's me) and will need to do 2

X 800000 Baht for bank accounts. From the conversations this year, it appears that this is where we need an agent. I should know this answer but I'll put it out there. That will mean two separate agent fees for 2 bank accounts I suspect?

Got his nice dilemma asked by private message;

I took a job at a company inside Thailand. The company is managed by a foreigner.

After 4 months I noticed that there are problems in the company and the company does not treat me good enough.

The discussed salary is not enough for me and I decided that the tax payments should not be made out of my salary as by Thai law.

Now I want to leave this company, but part of the contract

we both signed is a one month notice before leave.

Before I started to work they made the Work Permit and I have the Non Immigrant B visa?

As this is Thailand is it okay, to just leave and go do something else?
