GST/HST for Canadian Resellers: When Your Side Hustle Becomes a Business
Share to
Selling a few thrifted items on the side is not the same as running a business in the CRA’s eyes—but the line is closer than most casual resellers think.
Hobby income vs business income
The CRA generally treats casual, occasional selling as non-taxable hobby activity. Once you’re sourcing with the intent to profit and doing it regularly, it starts looking like a business.
The $30,000 threshold that changes everything
Once your business earns $30,000 or more in gross revenue over four consecutive quarters, you’re required to register for a GST/HST number and start charging tax.
Marketplaces already collect some of this for you
eBay and similar platforms now collect GST/HST on certain Canadian sales automatically, but that doesn’t remove your own reporting obligations at tax time.
Track everything from day one
Keep receipts for what you paid, what you sold for, and your shipping costs. It’s far easier to prove a hobby stayed a hobby than to reconstruct it after the CRA asks.
None of this is tax advice—talk to a Canadian accountant once your flipping gets serious. What ThreadFlip can do is help you track what each item actually sold for, so your records are ready when you need them.
