Do I need to be certified or licensed to file other people's income tax.
I live in Calgary, Alberta, Canada.
You have to possess a license or be certified to become a tax preparer in Canada. Failure to have the license might cause you hefty fines or a jail term. You should also be registered with the tax educational council in your state.
Yes, you may get in serious trouble if you arent
I do think you could make up the taxes for friends and family though, without having a license...
