Canadian Side Hustle Bookkeeping Tracker (T2125 + GST/HST) — Excel & Google Sheets

Running a side hustle in Canada on top of your day job? This bookkeeping spreadsheet keeps your sales, receipts and business kilometres in one place, then totals everything in the same order as CRA Form T2125 — and watches the $30,000 GST/HST small-supplier threshold for you.

Made for Canadian sole proprietors: Etsy and craft-market sellers, DJs, freelancers, creators, tutors and other side businesses. The tax year starts at 2026 (what most people file in early 2027); you can change it on the Settings tab.

WHAT'S INSIDE

• Income log — 1,000 rows; sales, fees/commissions and other income; GST/HST and PST/RST/QST collected columns for T2125 amount 3B; taxable-supply mark (Yes, Zero-rated or No — blank counts as Yes and is flagged)
• Expense log — 1,000 rows; every category is mapped to a T2125 line (advertising, office, professional fees, travel, utilities and more); business-use % for mixed personal/business costs. Enter meals in full — the 50% limit is applied on the T2125 Summary
• Mileage & vehicle tab — trip log plus yearly vehicle costs (with a GST/HST column for registrants), follows T2125 Chart A amounts 1–16 (including amount 11) to give your line 9281 amount
• Home office tab — workspace %, hours-per-day factor for mixed-use space (T4002), and T2125 Part 7, with carry-forward when it can't be used
• Monthly summary — income, tax collected, expenses, net and km for every month, with a chart
• T2125 Summary — line-by-line totals (8000, 8299, 8518, 8521 … 9270, 9369, 9945, 9946)
• GST/HST small-supplier tracker — rolling 4-calendar-quarter total, with warnings at 80% and 90% of $30,000 (you can change the warning levels); a blank taxable-supply mark is counted and flagged; once a quarter is over the threshold, later quarters stay over
• Settings — tax year (default 2026), province/territory (example default MB — change to yours; it is a label only), GST/HST registered yes/no, inventory, CCA, and taxable supplies from associates or other businesses you run
• How to Use tab — short setup steps, including how to open the file in Excel or Google Sheets, a not-tax-advice note, and what this workbook does not do
• A blank copy for your own numbers and a filled-in SAMPLE copy so you can see it working

PLEASE NOTE

• This is a record-keeping tool, not tax advice. Line numbers were checked against the 2025 CRA T2125 form; CRA can change forms each year. Please confirm what you can claim, and whether you need to register for GST/HST, with an accountant or CRA.
• Canada only (CRA). Amounts are in Canadian dollars. GST/HST and PST/RST/QST rates are not built in — you enter the actual tax shown on each receipt or invoice.
• Not covered: capital cost allowance calculations, the GST/HST quick method, partnerships, and passenger-vehicle interest and lease limits (T2125 Chart B and Chart C). Type any CCA amount from your own chart on Settings (line 9936). Apply Chart B/C limits yourself before typing interest or lease amounts on the Mileage tab.
• Marketplace and platform fees (for example Etsy listing, transaction and payment fees) are categorized as Other expenses (T2125 line 9270) in the sample. That is a starting point only — please confirm the right line with your accountant.
• If a file will not open, contact the shop and I'll help.

How this was made: I designed this template myself — I chose the layout, features and categories and wrote the instructions. I used AI tools to help draft formulas/text and to speed up mockups, and I tested and edited everything by hand.
