If the CRA audits your DoorDash or delivery income in Canada, their main target is usually your motor vehicle expense claim. To legally defend your deductions, you must provide a detailed daily mileage log showing exact kilometres driven for business versus personal use. Without this log, the CRA will likely deny your expenses and issue a tax bill.
The gig economy has exploded across Canada, with thousands of people delivering food for DoorDash, UberEats, and SkipTheDishes. Whether you are zipping through downtown Toronto or navigating the suburbs of Calgary, earning extra cash as a delivery driver means you are legally considered self-employed. This requires filing a T2125 form with the Canada Revenue Agency (CRA) to declare your income and claim business expenses.
As of May 2026, the CRA has significantly increased its audits of gig economy workers. 📈 Because delivery drivers frequently claim large motor vehicle expenses to offset their income, auditors are carefully reviewing these tax returns for errors or inflated deductions. If you receive an audit letter, do not panic, but you must act quickly and provide the right evidence. Let us walk through how to handle a CRA review of your delivery gig taxes.
Step-by-Step Process for Handling a CRA Gig Worker Audit in Canada
Receiving a brown envelope from the CRA can be stressful, but the process is highly standardized. Whether you live in Vancouver, Halifax, or Montreal, the federal tax audit procedure follows these clear steps. Most gig workers can resolve the issue by providing organized documentation.
Step 1: Read the CRA Processing Review Letter
Your first step is to carefully read the letter. 🔍 Often, this is not a full-scale audit but a “processing review” where the CRA asks for proof of specific lines on your tax return, usually your motor vehicle expenses, cell phone bills, or insulated delivery bag receipts. Note the strict 30-day deadline printed on the letter.
Step 2: Gather Your Golden Ticket: The Mileage Log
The CRA demands a comprehensive logbook to prove your business kilometres. You must provide a record showing the date, destination, purpose of the trip, and exact distance driven in kilometres for every single delivery shift. Simply taking a screenshot of your “active time” from the DoorDash app is generally not enough for the CRA.
Step 3: Compile Your Expense Receipts
Next, gather all your vehicle-related receipts for the tax year. 💮 You need proof of gas, oil changes, insurance, car repairs, and vehicle registration. The CRA calculates your allowable deduction based on the percentage of business use. For example, if you drove 10,000 km in total and 4,000 km were for UberEats, you can claim 40% of your total vehicle costs.
Step 4: Submit Your Documents Online
Do not mail physical receipts if you can avoid it. The safest and most efficient way to respond is by logging into your CRA My Account. Use the “Submit Documents” feature, enter the reference number from your audit letter, and upload clear PDF copies of your mileage log and receipts.
Step 5: File a Notice of Objection if Denied
If the CRA auditor rejects your logbook because it is incomplete, they will issue a new Notice of Assessment demanding more taxes. ⚀️ If you disagree with their decision, you generally have until the later of 90 days from the date the Notice of Assessment was sent, or one year after your filing-due date for that tax year, to file a formal Notice of Objection. At this stage, many delivery drivers choose to consult a Canadian tax lawyer or an accountant to build a stronger case.
How Much Does It Cost to Resolve a Gig Worker Tax Audit?
Handling a CRA audit is free if you do it yourself, but making mistakes can cost you thousands in denied tax deductions. 💵 Here is a breakdown of the typical costs and financial impacts a Canadian delivery driver might face.
- CRA Penalties: If the CRA determines you deliberately falsified expenses, they can apply a gross negligence penalty, which is 50% of the understated tax.
- Interest Charges: Any unpaid tax resulting from denied expenses will accrue compound daily interest at the current prescribed CRA rate (which is 7% per year as of June 2026).
- Accountant Fees: Hiring a CPA to reconstruct your mileage log or organize your receipts typically costs between $500 and $1,500 CAD.
- Tax Lawyer Retainer: If you must file a Notice of Objection or go to the Tax Court of Canada, a tax lawyer usually requires a retainer starting around $3,000 to $5,000 CAD.
| Type of Expense | CRA Documentation Required | Common Audit Pitfall |
|---|---|---|
| Gas and Fuel | Detailed receipts, bank statements | Only providing a credit card statement without itemized receipts |
| Vehicle Repairs | Mechanic invoices showing date and car VIN | Claiming 100% of the repair when the car is also used personally |
| Cell Phone Bill | Monthly carrier statements | Claiming the device purchase price as a current expense (must be capitalized) |
How Long Does the Process Take?
CRA reviews require patience. You typically have 30 days to submit your documents after receiving the initial letter. Once submitted, the CRA generally takes 2 to 6 months to review your files and issue a final decision. If you file a Notice of Objection, expect to wait 6 to 12 months before an Appeals Officer even looks at your case.
Frequently Asked Questions (FAQ)
Can I just use the mileage summary provided by the delivery app?
Generally, no. Apps like DoorDash only track your kilometres while you are actively on a delivery. They do not track the kilometres you drive between hotspots or returning to your delivery zone. The CRA requires a comprehensive manual logbook or a dedicated third-party GPS tracking app to prove your total business driving.
What happens if I did not keep a mileage log?
If you have absolutely no logbook, the CRA will almost certainly deny all your motor vehicle expenses. You may be able to reconstruct a log using your delivery app history, Google Maps timeline, and auto repair records showing odometer readings, but it is a difficult process.
Can I claim 100% of my car expenses if I only use it for work?
Claiming 100% business use is an immediate red flag for CRA auditors. Unless you have a second personal vehicle and can prove the delivery car is exclusively for work, the CRA will assume you use it for some personal errands (like groceries) and will demand proof.
Can I claim the cost of my e-bike or bicycle for deliveries?
Yes, but differently than a car. A bicycle or e-bike is considered a capital asset. You cannot write off the entire purchase price in one year; instead, you must claim Capital Cost Allowance (CCA) to deduct a portion of the cost over several years.
Will the CRA audit me for past years?
Yes. The CRA normally has the legal right to audit your tax returns for up to three years from the date of your original Notice of Assessment. If they suspect gross negligence or fraud, they can audit as far back as they want.
