What is NorthOS?

NorthOS is a Canadian-hosted bookkeeping app for sole proprietors and small businesses that automatically tracks your GST/HST remittance and maps your expenses to the CRA's T2125 form for tax time.

It's built for Canadian sole proprietors who don't want to manage spreadsheets or full accounting software, but still need to stay compliant with GST/HST thresholds and CRA rules.

Who is NorthOS for?

  • eBay, Etsy, and marketplace sellers in Canada
  • Freelance service providers: designers, copywriters, therapists, and tutors
  • Resellers and arbitrage-style sellers
  • Canadian sole proprietors under or near the $30,000 GST/HST threshold
  • Side-hustlers who want to stay CRA-compliant without hiring a bookkeeper

NorthOS vs spreadsheets and other accounting tools

NorthOS replaces the bookkeeping spreadsheet with an automated, CRA-aligned ledger that tracks your GST/HST remittance and T2125-ready expenses automatically.

Unlike QuickBooks Self-Employed - which Intuit is discontinuing in Canada - NorthOS is built specifically for Canadian GST/HST-aware sole proprietors and small businesses, with the $30,000 threshold, Quick Method and Regular Method remittance, and T2125 mapping built in from day one.

Frequently Asked Questions

When should I register for a GST/HST number?

In Canada, you must register for a GST/HST account once your taxable revenue exceeds $30,000 over four consecutive calendar quarters. NorthOS includes a Tax Threshold Tracker that monitors your income, providing alerts before you hit the CRA limit to ensure you stay on top of your GST/HST obligations without the stress.

Does NorthOS support T2125 and T776 tax forms?

NorthOS automatically organizes your business income and expenses to match CRA T2125 categories, so when tax season arrives, your records are already sorted. It also supports T776 (Real Estate Rentals), including rental income, expenses, and CCA tracking for landlords.

Can I use NorthOS if I'm not registered for GST yet?

Yes. NorthOS is built for exactly that stage. If you're under the $30,000 threshold, NorthOS tracks your revenue so you know where you stand. You'll get an alert before you hit the limit so you're never caught off guard.

Does NorthOS use the Quick Method or Regular Method for GST/HST?

NorthOS supports both the Quick Method and the Regular Method: you choose which one applies to your situation. The Quick Method is a CRA-approved simplified remittance approach available to most businesses under $400,000 in annual taxable sales; instead of tracking every individual ITC, you remit a flat percentage of gross revenue. The Regular Method tracks your actual ITCs and may suit businesses with significant input costs. Either way, your remittance is calculated automatically every time you log income. For complex tax situations, we always recommend working with a Canadian accountant. NorthOS makes sure your records are organized and ready when you need them.

What does NorthOS do for Canadian sole proprietors?

NorthOS handles the bookkeeping tasks that trip up most Canadian sole proprietors: tracking your revenue against the $30,000 GST/HST registration threshold, calculating your Quick Method remittance automatically, categorizing expenses to CRA T2125 lines, and scanning receipts. At tax time, your records are already sorted by T2125 category, so you or your accountant can file without reconstructing the year from a shoebox of receipts.

Does NorthOS handle GST/HST for sole proprietors and side hustlers under $30,000?

Yes. NorthOS is built for both stages. If you're under the $30,000 threshold, NorthOS tracks your cumulative taxable revenue and alerts you before you hit the CRA limit, so you register on time and avoid penalties. Once you're registered, NorthOS automatically calculates your Quick Method remittance on every income entry and keeps a running Safe-to-Spend balance so you never accidentally spend money that belongs to the CRA.

Founder Story

“In my first year reselling, I didn't know what a T2125 was. I spent hours on the CRA website trying to figure out what I actually owed — and left more confused than when I started. By year two I'd crossed $30,000 without realizing it. I was already required to be GST registered and had no idea. Every bookkeeping app I tried gave me a P&L. Nobody gave me a T2125. So I built NorthOS.”
