I am currently running my shop for about 3-4 months. I have not charged my customers taxes, also did not register for tax ID because I have not making insane amount of money yet. I heard that Shopify would send you a notice when your sales hit an amount that your shop should acquire a business license and a sale permit, then you have to get those otherwise Shopify would shut down your shop. Is it true? if it is true, How much would it be the target for Shopify to send out their notice? Also, Am I supposed to wait for a report from Shopify so I can file my taxes? Because it is an income now right?
