The side hustle is real. The bookkeeping should be too.
NorthOS tracks the GST/HST $30,000 threshold across every side hustle, maps your expenses to the right T2125 lines, and keeps your day job and side income cleanly separated, so you walk into tax season ready instead of scrambling.

Side hustle takes a lot of shapes.
NorthOS works for whichever one is yours. The CRA does not care what the work is called; the T2125, the $30,000 threshold, and the deduction rules apply the same way.
Gig drivers and couriers
Uber, Lyft, DoorDash, Instacart, SkipTheDishes. GST/HST is mandatory from dollar one for ride-share drivers, and the deductible-mileage logic is built in.
GST for delivery driversFreelancers with a day job
Designers, writers, developers, consultants. Day-job T4 income is tracked separately from side-hustle T2125 income, so they do not get tangled at filing time.
See the freelancer pageTutors and coaches
In-person and online. Most session-based work is GST-exempt below the $30,000 threshold and taxable above it. NorthOS shows you where you stand.
When to registerHosts and landlords
Airbnb, VRBO, and small landlords. Short-term rental income flows to T2125; long-term rental income flows to T776.
See the landlord pageOne-client consultants
A single contract on the side of full-time employment. CRA still wants a T2125 for the contract income, and a clean expense log can meaningfully reduce the tax bill.
Deductible expensesBuilt for how side hustlers actually file.
Everything NorthOS does is in service of one outcome: a clean T2125, the right GST/HST remittance, and no surprises in April.
The $30K threshold is on the dashboard.
Side hustles cross the GST/HST registration threshold by accident. The number that matters is rolling four-quarter revenue, and most people do not track it. NorthOS shows it against the $30,000 line so registration happens on time.
Every expense lands on a T2125 line.
No mapping from a vendor-named “Office Supplies” bucket to a CRA line at year end. Categorization happens at entry, with the right T2125 line attached. The export is the form.
Safe to Spend, on net side hustle income.
Your dashboard shows what is genuinely yours after income tax, CPP, and GST/HST are set aside. The number on screen is the number you can actually move into your personal account.
Drop a receipt in Drive, get a transaction.
Most side hustlers do not have time for double-entry bookkeeping. Save the receipt to a Google Drive folder; North AI reads it, categorizes it, attaches it to the right transaction.
Quick Method, one click.
Once you register, most side hustlers under $400,000 in revenue qualify for the CRA Quick Method, which keeps more GST in your pocket. NorthOS has the calculator built in for every province.
Day job income stays separate.
Your T4 employment income belongs to your employer. Your side hustle income belongs on a T2125. NorthOS only tracks the second one, so the two never get accidentally pooled.
You have a full-time job. You can still file this correctly.
A lot of Canadian side hustlers get nervous about the T4-plus-T2125 combination because they have only ever seen one of them. The two are not in conflict. They live in different sections of the same T1 personal return.
Your T4 is handled by your employer. Income tax, CPP, and EI are withheld at source. You do not touch any of that for your side hustle.
Your T2125 reports the side hustle income and expenses.It is a separate form (officially “Statement of Business or Professional Activities”) that attaches to your T1 and reports gross side hustle revenue, deductible expenses, and net self-employment income. NorthOS produces the export with every CRA line populated.
The two get summed together for tax owed. Your total taxable income for the year is T4 employment income plus net T2125 self-employment income, minus deductions. The CRA looks at the combined number, but the two streams stay structurally separate in your books.
You probably owe a top-up at filing time. Your employer withholds tax based on your T4 alone; it does not know about the side hustle. The set-aside number on the NorthOS dashboard estimates the top-up so it is not a surprise in April.
