Self-Employed Tax Deductions: Which Receipts to Keep

When you work for yourself, every legitimate business expense you can document lowers your taxable income. The catch is the documentation. A deduction you can't back up is a deduction you can lose in a review. Here's which receipts actually matter, what each one needs to show, and how to keep them without turning your desk into a filing cabinet.

The rule behind every deduction

Tax authorities let you deduct expenses that are ordinary and necessary for your line of work — costs that are common in your field and genuinely help you earn income. The expense has to be for the business, not personal life, and you need a record that proves it happened. That record is almost always a receipt. If the money left your account for a business reason and you can show it, it generally counts. If you can't show it, assume you can't claim it.

Which receipts to keep

You don't need to save every scrap, but the following categories are the ones that add up and the ones reviewers look at first:

• Supplies and equipment — anything you buy to do the work: tools, materials, software subscriptions, a laptop, a printer.
• Home office costs — a portion of rent, utilities, and internet if you use a dedicated space for work. Keep the underlying bills.
• Vehicle and travel — mileage logs, fuel, parking, tolls, flights, and lodging for business trips. Note the business purpose of each trip.
• Meals with a business purpose — client or partner meals. Jot down who you met and why on the receipt.
• Professional services — fees paid to accountants, lawyers, contractors, and freelancers you hire.
• Marketing and fees — advertising, website hosting, payment processing, bank charges, and professional dues.
• Insurance and licenses — business insurance premiums and any permits your work requires.

When you're unsure, keep the receipt. Storage costs nothing; a missing record can cost you the deduction.

What each receipt must show

A receipt only helps if it's complete. For a deduction to hold up, the record should make four things clear:

• Merchant — who you paid.
• Date — when the expense happened.
• Amount and tax — the total you're claiming and any sales tax paid.
• Business purpose — what it was for, tied to how you earn income.

Bank and card statements are useful supporting evidence, but on their own they usually aren't enough — a line that reads "$180, office supply store" doesn't prove what you bought or why it was for the business. The itemized receipt does. Keep both when you can.

How long to keep them

As a rule of thumb, hold supporting records for at least 6 years in Canada (CRA) or 3 years from your filing date for most US (IRS) situations — longer if you underreported income or claim certain losses. Because self-employment records can draw closer scrutiny than a simple salaried return, the safe move is to keep everything for the longest window that could apply to you. Digital copies take no space, so there's little reason to purge early.

Stay audit-ready without the shoebox

The failure mode for most self-employed people isn't dishonesty — it's a pile of faded thermal paper they meant to sort "later." The fix is to capture each receipt the moment it lands, while you still remember what it was for:

1. Photograph the receipt on the spot — crumpled or curled is fine.
2. Let the app pull the merchant, date, total, tax, and line items, then auto-categorize with a confidence score so you can spot the ones worth a second look.
3. Add a quick note of the business purpose for meals and travel, and move on.

Everything syncs across your iPhone and the web on one account, so a receipt you snap on the road is on your desktop when you sit down to do the books. At tax time you export a single books-ready CSV instead of retyping a year of paper — and if anyone ever asks you to back up a deduction, the record is already there.
