A spreadsheet for self-employed Canadians. Log your expenses, income, mileage, vehicle and home-office costs as you go. It works out the T2125 line and deductible amount for every entry, so tax time is copying totals, not digging through receipts.

What's inside
One tab for each part of your year. Type in the green cells; everything else adds itself up.
Expense Log
Pick from 24 categories, including materials and subcontractors for trades; the T2125 line and deductible amount fill in. Room for 2,000 entries.
Income Log
Sales and other income kept apart, plus the GST/HST you collected, the way T2125 wants them.
Mileage + Vehicle
Log trips and odometer readings; your business-use % flows into the vehicle claim.
Home Office
Your share of rent or mortgage interest, utilities and insurance, with the loss limit and carry-forward handled.
Dashboard
Totals by T2125 line, a monthly chart, GST/HST by quarter, and traffic-light checks that flag missing dates or categories.
T2125 Summary
Every line number with its total, ready to take to your accountant or tax software.

Questions
Google Sheets or Excel?
Both. You get a one-click copy for Google Sheets and an .xlsx file for Excel.
Is this tax advice?
No. It's a tool for keeping your records organized. Have your accountant review your numbers before you file.
I already use Monby. Do I need to buy it?
No. Beta users get it free, and can fill it with every receipt they've sent Monby in one click.
Does it work in Quebec?
Not yet. It covers the federal T2125 and GST/HST. If you're in Quebec, you also file with Revenu Québec (QST and form TP-80), and the template doesn't handle those.
