Thanks. I have read about the GST credit thing and I do keep all receipts for tax anyway. I was just wondering when it comes time to actually register for GST.

With the $75,000 limit. Say when comparing a B&M store and online store with the exact same sales volume (same number of items sold and item price). The online store would need to register for GST earlier because they have more money comming in as a result of needing to post items?
