Should the business buy the vehicle, or should you?
The vehicle costs the same either way — the tax treatment doesn’t. GST input tax credits, CCA, the standby benefit, and the per-km allowance all turn on who’s on title. We compare the BC after-tax cost of each route and tell you the business-use percentage where they cross.
Pick the right tab (incorporated or sole proprietor). Enter the vehicle price, your annual kilometres, and what share of those kilometres are for business. The cards compare after-tax cost over your hold period and the verdict tells you which route has the lower after-tax cost for your numbers.

At what business-use share do the two options have equal after-tax cost? On pure tax math at BC small-business rates, the per-km allowance is hard to beat — the breakeven often sits above 100%, meaning outside wins across the range.
When a corporation owns an automobile and makes it available to an employee or shareholder for personal use, the personal-use share becomes a taxable benefit on the individual’s T4 (or s. 15(1) shareholder benefit). It has two parts — a standby charge for the availability of the vehicle, plus an operating cost benefit for personal kilometres — with a generous reduction once business use exceeds 50%.

GST input tax credit — how proration works
The ITC, the two tax shields, and the per-km allowance — the mechanics behind each row.
Inside the corporation: ITC, CCA & operating shields
Three deductions stack when the corp owns the vehicle.
Expand for detailsHide details
Ceiling 1 — the prescribed amount. For passenger vehicles, the ITC is calculated as if the vehicle cost the prescribed amount ($39,000 for gas; $61,000 for ZEVs). Spend more and the extra GST is simply lost — no ITC at all on the overage.
Ceiling 2 — commercial use. Only the share of use in commercial activity qualifies. A 70% business / 30% personal vehicle generates 70% of the otherwise-allowable ITC.
The CCA tax shield. The corp can’t deduct the purchase price outright — it deducts capital cost allowance, a yearly depreciation write-off. Vehicles use a 30% declining-balance rate (30% of the balance remaining each year, so the deduction shrinks over time), and only half the rate is allowed in year one. The deduction isn’t the saving; the saving is the tax the deduction avoids: CCA × corporate rate. At the BC small-business rate of 11%, every $1,000 of CCA is worth $110 in cash. On a passenger vehicle the write-off is capped at the prescribed amount — a $55,000 car is depreciated as if it cost $39,000.
The operating cost shield. Fuel, insurance, and repairs the corp pays are 100% deductible to the corp — not prorated — because a corporate-owned vehicle is a corporate asset. The shield is operating costs × corporate rate. The personal-use slice is clawed back separately through the T4 operating-cost benefit ($0.34/km of personal driving), so the corp deducts everything and the driver is taxed only on their personal share.
Per-km allowance ITC. If the corporation pays a reasonable per-km allowance to an employee or owner for a personally-owned vehicle, the corp can claim an ITC equal to 5/105 × the allowance paid — effectively recovering GST embedded in the allowance.
| Year | Class 10.1 (gas) | Class 54 (ZEV) | Allowance ≤ 5k km | Allowance > 5k km |
|---|---|---|---|---|
| 2026 | $39,000 | $61,000 | $0.73 | $0.67 |
| 2025 | $38,000 | $61,000 | $0.72 | $0.66 |
Business vs personal use allowance
How personal driving gets taxed — differently in each structure.
Expand for detailsHide details
Incorporated — corp owns: personal use creates a taxable T4 benefit on the employee/owner — the standby charge (for availability) plus the operating cost benefit ($0.34/km of personal driving for 2025/2026). Both can be reduced when business use exceeds 50%. See the dedicated standby calculator on the incorporated tab for the step-by-step.
Incorporated — personal owns: the corporation can pay a tax-free per-km allowance (up to CRA’s reasonable rate). The allowance is deductible to the corp, tax-free to the owner, and lets the corp claim an ITC at 5/105. No standby charge in this path — the vehicle is the owner’s, not the corp’s.
The corp tax shield on the allowance. When the corp pays the allowance it books a deductible expense (motor-vehicle / travel), saving corporate tax of allowance × corporate rate — 11% at the BC small-business rate. On top of that it claims a 5/105 ITC, recovering the GST deemed baked into the allowance. So a $9,680 annual allowance really costs the corp roughly $9,680 − 11% shield − ~$461 ITC.
Why “allowance paid by corp” shows in brackets. On a combined owner-plus-corp balance sheet that line nets to zero: the corp pays the cash out, the owner receives the identical cash in. Money moving between your own pockets isn’t a family-level cost, so it’s shown in parentheses and excluded from the total. The only pieces that genuinely lower what the vehicle costs the family are the two real reductions the payment triggers — the corp’s tax shield and its 5/105 ITC — which is why those appear as negative lines while the allowance itself does not. A bonus not scored here: the allowance pulls cash out of the company completely tax-free, versus a salary or dividend that would be taxed in your hands.
When corporate ownership wins: the more a vehicle is used for business, the better the corporate-ownership math gets — and it’s strongest at near-100% business use. The clearest candidate is a non-passenger motor vehicle — a genuine work truck driven almost entirely for the business — because it escapes the Class 10.1 cap, gets the full GST ITC, and carries no standby charge. For a mixed-use passenger vehicle, the tax-free per-km allowance is usually the lower-cost route. Don’t anchor on a fixed percentage — let the calculator’s after-tax totals decide for your actual numbers.
Sole proprietors: no separate legal entity, so no standby charge and no tax-free allowance from yourself. Personal use is just excluded from the deduction. Claim the business-use share of actual costs on T2125, with the same Class 10.1 / 54 capital-cost cap and prorated ITC.
Passenger vehicle vs. motor vehicle — and why the toggle matters
Two CRA definitions that quietly rewrite the whole calculation.
Expand for detailsHide details
Everything above assumes a passenger vehicle — CRA’s term for an automobile: a road vehicle built mainly to carry people, seating nine or fewer including the driver. Most cars, SUVs, and half-ton trucks used around town land here, and three restrictions come with the label: the Class 10.1 CCA cap ($39,000), the matching ITC cap, and the standby charge on personal use.
A motor vehicle that is not a passenger vehicle is a different animal in the Income Tax Act. The common cases: a pickup or van seating no more than the driver and two passengers, used more than 50% to transport goods or equipment to earn income; a pickup seating more that is used 90%+ for business; or a dedicated work truck. These escape all three restrictions:
| Passenger vehicle | Non-passenger motor vehicle | |
|---|---|---|
| CCA class & cap | Class 10.1 — capped $39,000 | Class 10 — full cost |
| GST ITC | Capped at prescribed amount | Full GST × biz share |
| Personal use | Standby + $0.34/km benefit | Reasonable-value benefit |
Flip the Vehicle class toggle at the top of the calculator to Motor (non-passenger) and the engine drops the cap, gives the corp full ITC on the actual cost, and removes the standby charge — which is why a genuine work truck is much cheaper to hold inside the corporation than a comparable passenger vehicle. The ideal corporate-owned vehicle is one driven ~100% for business — a dedicated work truck with no personal use avoids the taxable-benefit question altogether. The catch is qualifying: the seating and business-use tests are strict, and CRA looks closely at pickups that double as family vehicles. If you’re not sure which side your vehicle falls on, that’s worth a quick check before you buy.
The fine print, briefly
How is the standby charge actually calculated?
The standby charge applies only to corporation-owned automobiles made available to an employee (ITA s. 6(1)(e)) or shareholder (s. 15(5)). Sole proprietors don’t have a standby charge — they simply prorate actual costs by business use on T2125.
For a purchased corporate-owned vehicle, the standby charge is:
Standby = (A ÷ B) × 2% × cost × months
Where A = personal km driven (or B if larger); B = 1,667 × months available. The reduction (A < B) only applies when business use > 50% and personal km are under 1,667 × months (20,004 km/yr if always available). Otherwise A = B and the full 2% applies.
The operating cost benefit is separate: $0.34/km × personal km (2025/2026 rate; $0.31 for sales/leasing employees). If biz > 50% and the employee notifies the employer in writing by December 31, they can elect to use 50% of the standby charge instead — whichever produces the lower benefit.
The dedicated calculator on the incorporated tab walks through this step by step. The top-bar simple / detailed toggle controls whether the main scenario comparison uses a quick proxy or the full CRA formula.
What counts as a “reasonable” per-km allowance?
CRA publishes prescribed per-km rates each year. For 2026 the rates are $0.73/km for the first 5,000 km and $0.67/km thereafter (2025: $0.72 / $0.66; plus $0.04/km in NWT, Yukon, and Nunavut — not BC). An allowance at or below these rates is presumed reasonable and tax-free to the recipient.
Pay above the rate and the allowance becomes taxable. Pay a flat monthly amount unrelated to kilometres and it’s also taxable. The allowance must be based on actual business kilometres driven.
Why does the calculator cap CCA on a passenger vehicle?
That’s the prescribed Class 10.1 capital cost limit for non-ZEV passenger vehicles ($39,000 for 2026; $38,000 for 2025). A vehicle costing $55,000 gets the same CCA shield as one costing $39,000 — the extra $16,000 generates zero deduction. The cost cap also drives the ITC ceiling for GST-registered claimants.
Zero-emission passenger vehicles use Class 54 with a higher cap of $61,000. There are also short-window incentives for ZEV immediate expensing that aren’t modelled here — ask first if you’re buying a new ZEV.
Is my vehicle a “passenger vehicle” or a “motor vehicle”?
A passenger vehicle (an automobile under ITA s. 248(1)) is built mainly to carry people and seats nine or fewer. It carries the Class 10.1 CCA cap, the ITC cap, and the standby charge. Most cars and SUVs qualify.
A pickup or van can fall outside the automobile definition — becoming a plain motor vehicle — if it meets a use test: it seats no more than the driver plus two and is used more than 50% to transport goods, equipment, or passengers to earn income; or it seats more and is used 90%+ in the business. A non-passenger motor vehicle has no CCA cap (Class 10, full cost), gets the full GST ITC, and has no standby charge. Use the Vehicle class toggle to model it. The tests are strict and fact-specific — if your truck also does the school run, confirm the classification before relying on it.
What about GST on operating costs?
GST on fuel, insurance, and repairs paid by a GST-registered business is generally recoverable as an ITC, prorated by commercial use just like the capital ITC. The calculator enters operating costs after-tax (i.e. as cash spent) for simplicity, which understates ITC recovery slightly. The directional answer doesn’t change — the bigger lever is the capital ITC and the standby benefit.
Insurance is GST-exempt in BC, so there’s no ITC on the insurance portion regardless.
Can I switch from personal ownership to corporate ownership later?
Yes — you can sell the vehicle to your corporation at fair market value at any point. The corporation pays GST/PST on the purchase (and claims the prorated ITC), restarts CCA on the new acquisition cost (still subject to Class 10.1 / 54), and you recognize any gain or loss personally. Two practical wrinkles: (1) the corp can only claim the ITC if it’s GST-registered and the vehicle is for commercial use; (2) PST is paid again on the transfer, which can be a meaningful cost — talk to us before doing this.
What does this calculator deliberately ignore?
Financing. We assume cash purchase to keep the comparison clean. Use our buy-vs-lease-vs-finance calculator if financing is part of the picture.
Recapture / terminal loss. Class 10.1 vehicles have special rules (no recapture, half-year deemed CCA on disposition); we apply the same special handling to Class 54.
Time value of money. Nominal cashflows only. For a sophisticated NPV, see the buy-vs-lease-vs-finance tool.
HST-province scenarios. BC-only — GST 5% + PST 7%. The arithmetic differs in HST provinces (recoverable ITC on the full HST changes the math).
ZEV incentive expensing (Class 54 100% first-year for new ZEVs). Phased out for many cases by 2025; we use straight 30% DB with the higher cap.
Let’s sanity-check it before you sign the bill of sale.
We’ll walk through your actual usage pattern, model the standby benefit on your numbers, and price the GST recovery you’re leaving on the table either way. Half an hour usually settles it.
