[Advice Needed] How To Be About My WooCommerce Store?

I know that nobody is a tax expert here, but who knows.

So I am from Canada, and have a stripe account that deposits directly into my bank. Should I change the bank info to Payoneer or something?

How high do incomes have to be to declare them? (I realize you should declare any income, but $100 a month doesn't seem worth declaring, but again, has anyone had dealt with something similar?)

How high should the income be to register a business? (Then I'll be able to expense lots of things and stuff, but i feel like the income should become significant first)

Sorry if that's too many questions, but let me know your thoughts? Thanks!

1. If you have legit biz u can use paypal or stripe connected to your bank
2. accounting and company holding is 2,000usd for year. It is up to u when u want to make it register business (later is better)
3. PayPal ask after you reach income of 10,000usd ask for documents and some time more.

Best is do it personal until payment processor ask you for tax info
