I an a french citizen married to a Taiwanese. We have been in Taiwan for a little more than a year and plan on staying here for the foreseeable future.
I have a small business (online language classes) registered in France that allow me to earn some money remotely. I declare all that I earn through it to the french authorities, and pay my taxes accordingly.
For now I have no other source of income. This business is just starting, After a few months dedicated to planning with no income I am now at the point where I can earn about 15000 TWD a month. There is potential for growth and I am aiming toward 25000/30000 (max) a month.
My customers are all french, I am paid in euros on a french account.
I have a dependent ARC and open working rights, so I do not think I am doing anything illegal.
I would like to know if I need to declare this income here, and if so when and how to go about it.
Also how much tax would I be expected to pay for this amount of money?
