TL;DR: A Driver Inc arrangement lets a truck driver incorporate and invoice the carrier as a contractor rather than receiving a T4. It can reduce payroll costs for carriers and tax overhead for drivers — but only when the working relationship genuinely reflects self-employment. When it does not, CRA reassesses the corporation as a Personal Services Business, claws back source deductions (CPP, EI, income tax), and stacks interest and penalties on both the carrier and the driver.
What Is Driver Inc?
Driver Inc refers to a truck driver who incorporates a small corporation — often a numbered company — and provides driving services to a carrier under a business contract rather than an employment agreement. The carrier pays invoices to the corporation instead of running the driver through payroll, and no T4 is issued at year-end.
The model grew rapidly in Canadian trucking through the 2010s because it offered advantages on both sides of the arrangement: carriers shed payroll overhead (EI, CPP matching contributions, vacation pay, WSIB/WCB premiums), while drivers deducted business expenses unavailable to T4 employees and, in some structures, accessed the small business deduction on corporate income. Provinces like Ontario and Quebec host the highest concentration of Driver Inc operators due to large cross-border freight volumes and dense contractor markets.
CRA has scrutinized the model for more than a decade. The core question is never the label — "contractor" or "incorporated driver" — but whether the substance of the work relationship fits self-employment under the agency's published criteria.
What Does the CRA Actually Test?
CRA applies a four-factor test drawn from common law and codified in guide RC4110 — Employee or Self-Employed?. No single factor is determinative; auditors weigh the full picture.
| CRA factor | Employee indicators (T4) | Independent contractor (Driver Inc) |
|---|---|---|
| Control | Carrier dispatches loads, sets routes, mandates ELD use, requires daily check-ins, sets hours of work, and dictates how loads are handled | Driver chooses which loads to accept, negotiates rates per load, sets own schedule, and operates without day-to-day supervision |
| Ownership of tools | Carrier provides the truck, trailer, fuel card, ELD device, and communications equipment; driver supplies only personal items | Driver owns or leases the truck and trailer, covers fuel and maintenance, and supplies their own ELD and telematics subscription |
| Chance of profit / risk of loss | Driver is paid a fixed rate regardless of fuel prices or load profitability; no personal financial exposure beyond missed shifts | Driver's net income fluctuates with fuel costs, deadhead miles, repair bills, and load mix; driver could lose money on a run |
| Integration | Driver's work is integral to and inseparable from the carrier's core business; driver does not market services to other carriers | Driver operates as a business, may haul for multiple carriers, carries their own cargo insurance, and is not exclusively woven into one carrier's operation |
Factor 1 — Control is typically the most important. If the carrier tells the driver when to work, which loads to take, and how to complete the work, the relationship looks like employment regardless of the paperwork.
Factor 2 — Ownership of tools in trucking almost always turns on who holds title to or is responsible for the power unit. A driver sitting in a carrier-owned truck pulling a carrier-owned trailer starts in a weak position on this factor.
Factor 3 — Chance of profit / risk of loss requires the driver's corporation to be exposed to genuine business risk. A flat cents-per-mile rate with no cost exposure does not demonstrate entrepreneurial risk.
Factor 4 — Integration asks whether the driver's services are so woven into the carrier's business that the driver effectively functions as part of the workforce, not an outside vendor.
When Does CRA Reclassify a Driver as an Employee?
When the four-factor analysis points to employment, CRA may reclassify the driver's corporation as a Personal Services Business (PSB) under Income Tax Act section 125(7). A PSB is sometimes called an "incorporated employee" — a corporation whose principal activity is providing services that would reasonably be regarded as the services of an employee if the corporation did not exist.
PSB status has severe tax consequences for the corporation itself: it loses access to the small business deduction (reducing the federal corporate tax rate to the general rate of 28% federally plus provincial corporate tax), cannot deduct most ordinary business expenses, and faces a 5% additional PSB tax surtax. Combined, the effective corporate tax rate can exceed 40% — higher than many individual marginal rates.
On top of the corporate tax hit, CRA will assess the carrier for unremitted source deductions: the employer's share of CPP contributions and EI premiums that should have been withheld and remitted, plus the employee's share that the employer is deemed to have failed to deduct. These amounts accumulate with interest from the date they were due — often years before the audit.
What Are the Penalties for Misclassification?
Both parties face exposure when an arrangement is reclassified:
For the carrier: - Liability for unremitted CPP and EI (employer + employee shares) for each misclassified driver - Failure-to-withhold penalties of up to 10% of the unremitted amount - Interest on outstanding amounts at the prescribed CRA rate, compounded daily - Potential reassessment of GST/HST input tax credits claimed on contractor invoices - Exposure to provincial payroll tax underpayments (EHT in Ontario, Quebec's FSS)
For the driver (and the driver's corporation): - PSB reclassification removing the small business deduction for all years under review - Personal reassessment if dividends or salary were structured to exploit the lower corporate rate - GST/HST obligations — a driver who invoiced as a business but whose supplies are reclassified as employment income may face HST clawback - Back income tax on amounts that should have been employment income
CRA audits can reach back three to six years, meaning a multi-year Driver Inc arrangement that later fails the four-factor test can produce a reassessment in the hundreds of thousands of dollars for a carrier with even a handful of affected drivers.
How Are 2026 Audits Trending?
CRA has publicly signalled that the trucking sector is a priority audit area for worker classification. The agency has conducted targeted industry reviews in Ontario and British Columbia, issuing advance letters to carriers asking them to demonstrate the legitimacy of their contractor relationships.
Several trends are shaping 2026 enforcement:
- Document requests at the border. CBSA occasionally flags Driver Inc arrangements during commercial border crossings and forwards information to CRA, particularly where the driver is operating a carrier-owned tractor.
- Information matching. CRA increasingly cross-references T4A filings (used to report contractor payments to incorporated payees) against corporate tax returns to identify discrepancies in expense claims and income characterization.
- ELD data. Because electronic logging devices record driving hours, carriers, and routes in detail, CRA has access — through compliance exchanges with Transport Canada — to operational data that can support or undermine a self-employment claim.
The trend is toward higher documentation standards, not necessarily more reassessments per audit. Carriers that can produce written contracts, evidence that drivers work for multiple carriers, and proof of genuine financial risk exposure are faring better than those relying solely on signed contractor agreements with no supporting business substance.
How Should I Structure My Driver Workforce?
There is no single correct answer — both T4 employment and legitimate Driver Inc arrangements can be compliant. The decision comes down to the actual working relationship, not the paperwork.
Use T4 employment when: - You control dispatching, routing, and load selection - You provide the truck, trailer, and ELD - Drivers work exclusively for your company - You set hours and require daily check-ins
Driver Inc may be appropriate when: - The driver genuinely owns or leases their own power unit - The driver accepts or rejects loads freely and works for multiple carriers - The driver carries their own cargo or liability insurance - The driver has real financial exposure to fuel, repairs, and empty miles
If you operate in Quebec, note that Revenu Québec applies parallel classification rules under the Act Respecting Labour Standards and the Taxation Act. A driver who is self-employed for federal CRA purposes may still be considered an employee under Quebec law depending on the specific relationship.
For carriers building or reviewing their fleet workforce, consult a Canadian tax professional before structuring large numbers of drivers as contractors. For drivers already operating through a corporation, review the four-factor test against your actual day-to-day arrangement — not the contract terms alone.
