Tax Guide for Uber, Lyft, and Ride-Share Drivers in Quebec: GST/QST Rules, Income Reporting, and Deductible Vehicle Expenses — CPA Firm Near You, Montreal

Introduction
Ride-share drivers working with Uber, Lyft, Eva, and other transportation platforms in Quebec face unique tax rules that differ from typical freelancers. GST/QST registration is mandatory from the first dollar of ride-share income, vehicle expenses must be tracked meticulously, and platform payouts can be inconsistent. Many drivers lose deductions or face reassessments because they do not understand the specific tax obligations for transportation services. This guide explains how ride-share drivers must report income, claim vehicle expenses, and comply with GST/QST requirements — and how a CPA firm near you in Montreal can help you stay fully compliant.
Legal and Regulatory Framework
Under the Income Tax Act and the Taxation Act of Quebec, all ride-share income must be reported as business income. Unlike most freelancers, ride-share drivers must register for GST and QST immediately — the small-supplier threshold does not apply to commercial passenger transportation. Drivers must collect and remit GST/QST on fares, although platforms like Uber may handle part of the remittance. Deductible expenses include fuel, repairs, insurance, car payments or leasing costs, parking, tolls, cellphone usage, car washes, winter tires, and a percentage of depreciation through capital cost allowance (CCA). CRA and Revenu Québec require detailed mileage logs, receipts, and platform payout statements to support all claims.
Key Court Decisions
Courts have repeatedly ruled that drivers may deduct vehicle expenses only in proportion to business use, based on accurate mileage logs. Several rulings denied deductions because taxpayers lacked logs, mixed personal and business use, or claimed unrealistic mileage. Judges also confirmed that GST/QST registration is mandatory for all drivers from the first dollar earned and that failure to collect and remit sales tax results in significant reassessments. Courts emphasized that platform statements alone are not enough — proper bookkeeping and receipts are essential.
Why CRA and Revenu Québec Target Ride-Share Drivers
Ride-share drivers are frequently audited due to inconsistencies between platform payouts, mileage logs, and declared expenses. Authorities use data provided by Uber, Lyft, and other platforms to cross-check income reporting. Large deductions for fuel, repairs, or leasing without proper documentation immediately trigger red flags. Missing mileage logs, cash payments, and informal expense tracking are leading causes of reassessment. Because GST/QST registration is mandatory from the start, many drivers face backdated tax bills when they do not register early.

Real Client Experience
A Montreal Uber driver was audited after declaring high fuel and repair deductions without mileage logs. CRA reconstructed income using platform data and attempted to deny most expenses. We rebuilt mileage records using trip history, validated receipts, and recalculated legitimate deductions. The reassessment was reduced significantly and the driver adopted a proper tracking system moving forward.
