Separate or combined tax declaration

As married couple, do we have to fill income tax declaration together or can we chose to fill it separately?

If you are married, they encourage you to file jointly and usually in the Taiwanese citizen’s name. There are different advantages to both, depending on your personal situation.

Thanks. So it means we can perfectly chose to file separately because we will be paying less tax? And this would be perfectly legal?

As I recall, yes. Give the tax office a call to verify.
