Here's a situation that's more common than it should be: a Canadian freelancer has a good year, crosses $30,000 in revenue without realizing it, and gets a letter from the CRA months later. Suddenly they owe back-collected GST/HST they never charged clients, plus penalties. It's a stressful, expensive mess — and it was entirely preventable. I built HST Hero because I kept hearing this exact story in freelancer communities. The $30,000 threshold isn't based on your fiscal year or calendar year — it's a rolling 12 months. That wrinkle catches a lot of people off guard, and almost no tool explains or tracks it clearly. HST Hero fixes that. You log your income as you go — or import it — and the app calculates your true rolling 12-month total in real time. You see a simple dashboard: your current revenue, your remaining room before the threshold, and a clear warning when you're getting close. No accounting degree required. Who it's for: - Canadian freelancers, consultants, and contractors - Sole proprietors who haven't registered for GST/HST yet - Anyone who gets paid project-by-project and loses track of annual totals - New self-employed Canadians figuring out their obligations for the first time What's free: The free plan supports up to 10 transactions — enough to try it out and understand how the rolling 12-month math works. We wanted the core value (knowing where you stand) to be free. What's paid: Pro is $5.99/month CAD. You get unlimited transactions, CSV export for your accountant or records, and priority support. No annual lock-in — cancel any time. This is a focused tool. It does one thing — tracks your GST/HST threshold exposure — and does it clearly. It's not a full accounting suite. If you want invoicing or bookkeeping, there are bigger tools for that. HST Hero is the thing you check to make sure you're not about to get blindsided. We're launching to get real feedback from Canadian freelancers. Does the dashboard make sense? Are we missing a use case? Is there a CRA rule we haven't accounted for? We'd genuinely love to hear from you — drop a comment or find us at hsthero.ca. If you know a Canadian freelancer who's winging it on the threshold question, send them this. It might save them a bad day.
