Hello.
I tried to follow your steps but failed.
I realized that maybe it's because I have no sin no., I'm a temporary resident and the tax no. is not the regular one.
such situation, it's possible for me to use ufile to declare tax?
I have several requests to do as a foreigner self-employee:
1. modify the 2022 tax declaration
2. create a new account to declare for 2023
if possible, please show me the method, thank you!
