Why use a template instead of starting from scratch?
Deductible expenses that aren’t tracked as they happen are the ones most likely to be forgotten entirely — and forgotten deductions mean paying more tax than necessary. Logging them consistently throughout the year, by category, means your tax preparation starts with a complete picture instead of a reconstruction project.
How to Use This Template
Download and open in Excel or Google Sheets
Works identically in either — no macros or add-ins needed.
Log deductible expenses as they happen
Real-time tracking is far more reliable than reconstructing months later.
Categorize consistently using CRA-aligned categories
This makes handing off to your accountant or preparing your own return much smoother.
Keep receipts referenced or filed alongside the log
CRA documentation requirements mean every deduction should be supportable if reviewed.
Run the built-in AI prompt before filing
Attach the saved file to ChatGPT or Claude and ask what commonly missed Canadian deduction categories to double-check.
Built-in AI prompt
Once you've filled this template in, it includes a ready-to-use prompt at the bottom of the sheet. Attach your saved file to ChatGPT, Claude, or any AI chat tool and paste it in — you'll get plain-English feedback on what commonly missed Canadian business deduction categories are worth double-checking before filing, based on the categories already logged, no accounting background required.
Common Mistakes to Avoid
Waiting until tax season to reconstruct deductions
This is exactly how deductions get missed — log expenses as they happen throughout the year instead.
Not keeping documentation for each deduction
CRA can request support for any claimed deduction — a deduction without a receipt or record is much harder to defend if reviewed.
Mixing personal and business expenses
Only genuinely business-related expenses are deductible — keep the two clearly separated, ideally through separate accounts.
Assuming a category is deductible without confirming
CRA deductibility rules vary by expense type and change over time — verify uncertain categories with your accountant or current CRA guidance.
