Can't in Canada. I own a small business. There's no way to legally pay your taxes to your business and not have them know who you are. In order to pay taxes on a small private business in Canada, you need a business number and a GST number. You can't get those and not have them know who you are / where you are / live.

Unless you can procure another SIN number and make that person your business owner. Get caught doing that though, wouldn't be good.

You could also arrange something with someone you trust, fully, where they are the owner of said business. You then, though, have to figure out how they will 'pay you' without a trail. But that person would be solely, legally, responsible for your business. They could easily fuck you, after you've made some good money , and just stop paying you. You'd have zero recourse.
