If you are a self-employed plumber, electrician, or HVAC technician in Canada, your truck or van is not just transportation — it is a rolling workshop. Hauling tools and equipment to multiple job sites each day means your vehicle is central to earning income, and plumber and electrician vehicle expenses in Canada can produce one of the largest deductions on your tax return.
This guide covers the 2026 CRA rules that matter most: reporting costs on T2125, the motor vehicle versus automobile classification, CCA for work trucks, the home-base advantage, and mileage logging for multi-stop routes.
Reporting Vehicle Expenses on T2125
Self-employed plumbers and electricians report business income and expenses on Form T2125 (Statement of Business or Professional Activities). Vehicle costs are entered in Part 4 of that form. The eligible expense categories include:
- Fuel and oil — gasoline, diesel, or propane
- Insurance — the annual premium
- Maintenance and repairs — oil changes, brakes, tires, engine work
- Licence and registration — plate renewal and municipal permits
- Lease payments — capped at $1,100/month before tax for 2026 leases
- Interest on a vehicle loan — capped at $350/month for 2026 loans
- Parking — at job sites and supply houses, not at your own shop
- Car washes — minor but deductible
You calculate your business-use percentage from your mileage log (business kilometres divided by total kilometres) and apply it to every line. For a detailed walkthrough of each T2125 field, see the T2125 vehicle expenses guide for self-employed Canadians.
The Home-Base Advantage for Trades Workers
The CRA treats travel between your home and a fixed place of business as personal commuting. However, most self-employed plumbers and electricians do not commute to a single shop. Home is the principal place of business — tools are stored there, scheduling and invoicing happen there, and each morning’s route starts there.
When home is your business base, every trip to a client’s job site is a business trip. The return from the last site back home is also business. This means nearly every kilometre in the work vehicle counts toward your business-use percentage.
A typical plumber doing residential calls leaves home at 7:30 a.m., visits four or five houses, stops at a supply warehouse, and returns home at 5 p.m. Every leg is business. The only personal kilometres are weekend errands. Business-use percentages of 85 to 95 percent are common for trades workers with a dedicated work vehicle.
Motor Vehicle vs Automobile — Why Classification Matters
The Income Tax Act draws a critical line between a “motor vehicle” and an “automobile” (also called a passenger vehicle). Automobiles face cost caps on CCA, leasing, and loan interest. Motor vehicles do not. For a trades worker buying a $55,000 service van, this distinction can mean thousands of dollars in extra deductions.
A vehicle escapes the automobile classification and is treated as a motor vehicle if it meets any of these conditions:
- Pickup or van seating 1-3 people (including driver), used more than 50 percent for business in the acquisition year
- Extended-cab pickup, SUV, or van seating 4-9 people, used 90 percent or more for business in the acquisition year
- Vehicle at a remote work location at least 30 km from the nearest community of 40,000+
- Permanently modified vehicle — a cargo van with rear seats removed and shelving or pipe racks installed no longer functions as a passenger vehicle
Most plumbers and electricians driving a cargo van with racking or a service body truck qualify as a motor vehicle. The classification is locked in the year you buy or lease, so getting it right from day one matters.
When your vehicle is a motor vehicle rather than an automobile, the 2026 Class 10.1 cost ceiling of $39,000 does not apply, the $1,100 per month lease cap does not apply, and the $350 per month interest cap does not apply. You deduct the actual amounts.
CCA Classes for Work Trucks and Vans
Once you know whether your vehicle is a motor vehicle or an automobile, the CCA class follows:
| Situation | CCA Class | Rate | Cost Cap |
|---|---|---|---|
| Motor vehicle (truck/van, not an automobile) | Class 10 | 30% | None |
| Automobile costing $39,000 or less (before tax) | Class 10 | 30% | None |
| Automobile costing over $39,000 (before tax) | Class 10.1 | 30% | $39,000 + tax |
| Zero-emission passenger vehicle over $61,000 | Class 54 | 100% first year | $61,000 + tax |
Example — Marco, a self-employed plumber in Ontario:
Marco buys a new Ford Transit cargo van for $52,000 plus HST. The van has no rear seats — it has custom pipe racks and a parts bin system. Because the van has been permanently modified and cannot carry passengers in the rear, the CRA classifies it as a motor vehicle, not an automobile. Marco places the full $52,000 (before tax) into Class 10 with no cost cap.
With 90 percent business use and the half-year rule in Year 1:
- Year 1 CCA: $52,000 x 30% x 50% x 90% = $7,020
- Year 2 CCA: ($52,000 - $7,800) x 30% x 90% = $11,934
If Marco’s van were classified as an automobile, the depreciable amount would be capped at $39,000. The Year 1 CCA would drop to $5,265 — a difference of $1,755 in the first year alone.

Real-World Example — 25,000 km per Year
Take a self-employed electrician named Sarah who drives a Ram ProMaster van across the Greater Toronto Area. She tracks every trip with Tripbook and logs 25,000 kilometres for the year. Her mileage log shows 22,500 business kilometres and 2,500 personal kilometres — a 90 percent business-use ratio.
Sarah’s annual vehicle costs:
| Expense | Total | Business (90%) |
|---|---|---|
| Fuel | $6,200 | $5,580 |
| Insurance | $2,400 | $2,160 |
| Maintenance and repairs | $1,800 | $1,620 |
| Licence and registration | $250 | $225 |
| CCA (Year 2, Class 10) | $11,934 | $10,741 |
| Total | $22,584 | $20,326 |
Sarah deducts $20,326 on her T2125. At a combined marginal rate of roughly 30 percent, that saves approximately $6,098 in income tax. She also claims HST input tax credits on fuel, maintenance, and the vehicle purchase itself — adding further recovery on top of the income tax deduction.
Keeping a CRA-Proof Mileage Log
Trades workers face a unique logging challenge. A desk-job employee might drive to one client meeting and back. A plumber or electrician might make six to eight stops in a single day:
- Home to Job Site 1
- Job Site 1 to electrical supply warehouse
- Warehouse to Job Site 2
- Job Site 2 to Job Site 3
- Job Site 3 to Home Depot for emergency parts
- Home Depot to Job Site 4
- Job Site 4 to Home
For each leg, the CRA expects the date, destination address, purpose of the trip, and kilometres driven. Recording odometer readings at the start and end of the fiscal year is also required.
Manual logging at this volume is impractical. A GPS mileage tracker like Tripbook runs in the background and records every trip automatically — start address, end address, distance, and route. At tax time, export the full log for your T2125. If the CRA audits, you have a complete, timestamped record.
After one full 12-month base year of logging, the CRA allows a simplified method: keep a log for a three-month sample period in subsequent years. If the sample business-use percentage falls within 10 percentage points of the base year, the CRA accepts a projected annual figure.

Self-Employed vs Employee — Key Differences
Not every plumber or electrician is self-employed. If you work as an employee for a plumbing company or electrical contractor, the rules change:
- Self-employed (T2125): Claim all eligible vehicle expenses directly, multiplied by business-use percentage. No employer form needed.
- Employee (T777): Must have a signed Form T2200 from your employer stating you are required to pay your own vehicle expenses. Deductions are claimed on Line 22900.
- Tradesperson’s tool deduction: Employees can claim up to $1,000 for eligible tool purchases (separate from vehicle expenses) if the employer certifies the requirement on Form T2200.
- Trades mobility deduction: Apprentices and journeypersons who relocate at least 150 kilometres for construction work can deduct up to $4,000 in transportation, meals, and lodging.
