How to Use This Printable

  1. Add a line every time you spend on something deductible, the same week it happens.
  2. Write the date, what it was, a category, the amount, and one line on the business purpose.
  3. Keep the matching receipt in one folder, digital or paper, labelled to match the log.
  4. Total each category before you file, or hand the sheet straight to your accountant.

Why the deductions people miss are the ones never written down

A deduction that isn't logged the week it happens is easy to forget entirely by the time filing season arrives, especially smaller purchases that don't feel significant in the moment.

Writing a real business purpose, not a placeholder

A specific note like "client meeting, discussed Q3 project" holds up far better than a vague "business expense" if the deduction is ever questioned.

Matching receipts to the log

Naming each saved receipt file with the same date and amount as its log entry means a specific expense can be verified in seconds rather than a search through a folder of unlabeled images.

FAQ

What kind of expenses go on here?
Anything you can legitimately deduct for your situation: home office costs, mileage, supplies, software, professional fees, and similar. Check what applies to you before claiming.
Do I still need receipts if I have the log?
Yes. The log is your running summary; the receipts are the proof. Keep both together for each year.
What if I forget to log an expense right away?
Add it as soon as you remember, using the actual purchase date rather than the date you logged it, so the log stays chronologically accurate.
Should personal and business purchases from the same receipt be split?
Yes, log only the deductible business portion and note how the split was calculated in the Business Purpose column.
Does keeping this log replace the need for an accountant?
No, it organizes the raw information; a tax professional still determines what's actually deductible for your specific situation.
