Of everything in this series, this is the provision most Canadian business owners are personally exposed to and least likely to have modelled. The corporation buys a vehicle, the owner drives it, and an amount appears on a T4 that nobody calculated deliberately.
Key Takeaway
Where a corporation makes an automobile available, two separate benefits arise: a standby charge under paragraph 6(1)(e) and an operating expense benefit under paragraph 6(1)(k). The standby charge for an owned vehicle is 2 percent of original cost for each month available, being 24 percent of cost annually, and it does not decline as the vehicle ages. Our own calculation shows a $60,000 vehicle produces cumulative taxable benefit equal to 120 percent of its original cost over five years. The charge can be reduced only where business use exceeds 50 percent and personal driving is under 1,667 kilometres a month, both of which must be evidenced. On our figures, the difference between having a logbook and not, on 5,000 personal kilometres, is roughly $4,644 of tax in a single year.
A Note On Currency
Everything here is stated as verified in August 2026 and requires confirmation before reliance. Prescribed rates and capital cost ceilings in this area are set annually and change.
We have not verified the statutory provisions against the Act, and the paragraph references are as commentary cites them. Rates are reported from commercial sources and should be taken from CRA's own published rates for the year concerned.
We accessed CRA's own guidance on employer-provided automobiles for the record-keeping requirements and worked examples[1], but the calculation detail below is drawn largely from professional and commercial commentary.
This is not tax advice. The decision whether a vehicle should be held corporately or personally turns on the specific numbers, and commentary quoted below is right that modelling is essential rather than optional.
Two Benefits, Not One
The structure, which is the first thing owners get wrong.
Commentary sets out the statutory basis: under paragraph 6(1)(e) of the Income Tax Act the standby charge applies when a vehicle is made available, and under paragraph 6(1)(k) the operating expense benefit applies when the corporation covers personal operating costs. It adds that these are not optional but statutory requirements[2].
CRA guidance is described as confirming that where a corporation makes an automobile available and there is personal driving, the taxable automobile benefit is generally the standby charge plus the operating expense benefit, minus any qualifying reimbursements[3].
The distinction matters enormously and this is our own emphasis.
The standby charge is a benefit for availability. Commentary describes it as the cost of simply having the vehicle available for personal use, whether you drive it or not[4].
The operating benefit is a benefit for use, measured per personal kilometre.
So an owner who drives almost no personal kilometres still has a standby charge, because the car was there. Reducing personal driving to nearly nothing does not eliminate the larger of the two amounts, and that surprises people who assume the benefit tracks their usage.
The Standby Charge Formula
The calculation, in both its forms.
Commentary states that when the automobile is owned by the employer, the standby charge is 2 percent times the cost of the automobile times the number of months available to the employee in the year, so that if the automobile is available 12 months of the year, 24 percent of the cost of the automobile is included in the employee's income each year[5].
Where the automobile is leased, the standby charge is two-thirds of the monthly lease costs, excluding insurance, times the number of months available[5][4].
Commentary notes the benefit can be calculated using CRA's automobile benefits online calculator or the prescribed form[5].
Two observations on the owned formula, both ours.
The base is cost, which is the amount the corporation paid, and there is no reference in that formula to the vehicle's current value.
And the multiplier is monthly, so the charge accrues by month of availability rather than by year. That gives the months-available figure real significance, addressed later.
The leased formula behaves differently in an important respect. Lease payments end when the lease ends and a replacement lease reflects the replacement vehicle's value, so the leased charge naturally resets. The owned charge does not, which is the subject of the next section.
The Feature Nobody Models
The consequence of computing on original cost, which we consider the most underappreciated point in this area. This section is our own analysis.
Every other number attached to a vehicle falls over time. Its market value falls. Its capital cost allowance base falls. Its insurance value falls. Its resale price falls.
The standby charge does not. It is 2 percent of what the corporation originally paid, every month, in year one and in year eight alike.
That produces a result that is arithmetically obvious and almost never modelled: the longer the corporation keeps the vehicle, the worse the arrangement becomes relative to the asset's value.
In year one, the owner is taxed on 24 percent of the cost of a car that is worth roughly its cost.
In year six, the owner is taxed on 24 percent of the original cost of a car that may be worth a quarter of it.
Two practical consequences follow.
The instinct to keep a corporate vehicle longer to get value from it is exactly backwards where a full standby charge applies. Holding it longer accumulates benefit against a declining asset.
And the comparison between corporate and personal ownership changes over the holding period. An arrangement that models acceptably over three years may be clearly poor over eight, which means the decision should be revisited rather than made once.
One Hundred And Twenty Percent
The figures, computed by us on a $60,000 vehicle available twelve months a year.
The annual standby charge is 2 percent of $60,000 times twelve, being $14,400, which is 24 percent of cost.
Cumulatively, that is $14,400 after one year, being 24 percent of the car's cost.
After three years, $43,200, being 72 percent of cost.
After four years, $57,600, being 96 percent of cost.
After five years, $72,000, being 120 percent of cost.
After eight years, $115,200, being 192 percent of cost.
Those are amounts of taxable income, not tax. At an assumed 43 percent marginal rate the tax on the five-year figure is roughly $30,960, again on our own calculation.
We would state plainly what those numbers do and do not show. They assume a full standby charge throughout, which is the position where the reduction described below is unavailable or unclaimed. Where the reduction applies, the figures are very different, which is the entire point of the logbook sections.
What they do show is the shape of the exposure at the default. An owner who has not established entitlement to the reduction is on this curve.
The Operating Expense Benefit
The second benefit, and its rate.
Commentary describes it as arising where the employer pays the vehicle's operating expenses such as fuel, maintenance and insurance[4], and as the value CRA assigns to employer-paid fuel, insurance and maintenance for every personal kilometre driven[6].
On the rate, commentary states it is 34 cents per personal kilometre in both 2025 and 2026, or 31 cents if the principal source of employment is selling or leasing automobiles[3]. Another gives the 2026 prescribed rate as generally 34 cents per personal kilometre, and slightly less for employees principally employed in selling or leasing[4].
We report those figures as commercial sources state them; the rate is set annually and should be taken from CRA's own publication for the year concerned.
Three points, ours.
The rate applies to personal kilometres only, so the same logbook that supports a reduced standby charge also determines this figure.
The rate is prescribed rather than actual, so it does not matter what the fuel actually cost. An efficient vehicle driven cheaply attracts the same per-kilometre benefit as a thirsty one.
And the benefit arises because the employer paid the operating costs. That is what makes the reimbursement route described below effective: if the employee bears those costs, there is nothing for the paragraph to attach to.
The Optional Method
An alternative computation for the operating benefit, with conditions.
Commentary describes an optional method equal to 50 percent of the standby charge before reimbursements, available only if a standby charge is included, business driving is more than 50 percent, and the employee notifies the employer in writing before year end[3].
Another describes it as available if elected and conditions met, noting the election must be made properly and is only available in certain situations[2].
The third condition is the one that costs people money, and this is our own emphasis.
A written notification before year end is a deadline that passes silently. Nobody sends a reminder, the amount at stake is not visible until the T4 is prepared, and by then the option is gone for that year.
Whether the option helps depends on the numbers. It produces a lower benefit than the per-kilometre method where personal kilometres are high relative to the standby charge.
On our own illustration, a $14,400 standby charge would give an optional-method operating benefit of $7,200. That beats the per-kilometre method only above roughly 21,000 personal kilometres at 34 cents.
So for an owner with modest personal driving the option is worth nothing, and for one with heavy personal driving it can be worth a great deal. The calculation should be run before the year-end deadline rather than after, which is the only time it can be acted on.
The Reduced Standby Charge
The relief that changes the whole picture.
Commentary states that for 2003 and later years the standby charge may be reduced if the kilometres driven for business use are at least 50 percent of total kilometres driven, noting the threshold was 90 percent prior to 2003[5].
Another sets out both conditions and the formula: the reduction applies when personal use kilometres are less than 1,667 km per month, being 20,004 km per year, and the vehicle is used primarily for employment, being more than 50 percent of total kilometres for business. The reduced standby charge formula is the standard standby charge multiplied by personal kilometres divided by 1,667 kilometres per month times the number of months[7].
Read the formula and the design becomes clear, which is our own analysis.
The figure of 1,667 kilometres a month is the level of personal driving the full standby charge assumes. The reduction prorates the charge by actual personal driving against that assumed level.
So an employee driving half that amount personally pays half the charge, and one driving a tenth pays a tenth.
That is a proportionate relief with no threshold effect once the conditions are met, which means every kilometre of personal driving avoided, and every kilometre correctly recorded as business, reduces the benefit directly.
Both Conditions, Not Either
A point worth isolating because the two tests do different work. This section is our own analysis.
The reduction requires business use above 50 percent and personal driving below 1,667 kilometres a month.
Those are not the same test and neither implies the other.
An owner driving 60,000 kilometres a year, of which 55 percent is business, satisfies the percentage test. But personal driving of 27,000 kilometres exceeds the annual threshold, so the reduction is unavailable.
Conversely an owner driving 8,000 kilometres a year with 5,000 personal satisfies the volume test easily, but business use is only 37.5 percent, so the reduction is again unavailable.
The second case is the common one for an owner-manager whose business is local. Low total mileage with a substantial personal share fails the percentage test even though the absolute personal driving is trivial.
That produces a counterintuitive result worth stating: an owner who barely uses the car at all can face the full standby charge, because the test is proportional rather than absolute.
The practical response for such an owner is not to drive more for business. It is to question whether the vehicle should be held corporately at all, which is the modelling point made at the end of this article.
What A Logbook Is Worth
The comparison, computed by us on the same $60,000 vehicle with 5,000 personal kilometres and business use above 50 percent, at an assumed 43 percent marginal rate.
Without a logbook, the reduction cannot be supported. The standby charge is the full $14,400. The operating benefit at 34 cents on 5,000 kilometres is $1,700. The total benefit is $16,100, and the tax is roughly $6,923.
With a logbook, the reduced charge is $14,400 multiplied by 5,000 over 20,004, being roughly $3,599. The operating benefit is the lesser of the per-kilometre figure of $1,700 and the optional method figure of $1,800, so $1,700. The total benefit is roughly $5,299, and the tax is roughly $2,279.
The difference is approximately $4,644 of tax in a single year, on one vehicle.
Across five years, roughly $23,222.
Commentary makes the same point without the arithmetic, observing that keeping a detailed logbook of business versus personal driving is financially worthwhile and can reduce the taxable benefit by thousands of dollars annually[7].
We would frame it more directly. The logbook is not a compliance chore attached to the vehicle. On these figures it is the single highest-return piece of record-keeping available to an owner-manager, measured against the time it takes.
A Dollar Thirty-Eight A Kilometre
The same comparison expressed differently, because it is the version that changes behaviour. These are our own calculations.
Without a logbook, the total tax of $6,923 arises on 5,000 personal kilometres. That is $1.38 of tax for every personal kilometre driven.
With a logbook, the tax of $2,279 on the same 5,000 kilometres is $0.46 per kilometre.
The first figure is worth sitting with. At a dollar thirty-eight a kilometre, a fifteen-kilometre trip to a restaurant carries about twenty dollars of tax.
Two observations follow, ours.
The high per-kilometre figure is an artefact of the standby charge being fixed. Because the charge does not vary with driving, dividing it across few personal kilometres produces a large per-kilometre cost.
That means the marginal cost of an additional personal kilometre is only 34 cents of operating benefit, while the average cost is far higher. The expensive part is not the driving; it is the availability.
Which points at the real lever. An owner in this position does not improve their outcome by driving less. They improve it by establishing entitlement to the reduction, by reimbursing, or by reconsidering the ownership structure.
The Commuting Trap
The single most common error, and it works against the taxpayer on both tests.
Commentary states that for most owners the biggest mistake is counting home-to-office driving as business use, and that CRA normally treats that as personal driving[3].
Another puts it as home-to-office travel being considered personal unless the home qualifies as a principal place of business, and notes many owner-managers incorrectly assume commuting is business use[2].
Consider the arithmetic effect, which is ours.
Commuting is typically the largest single category of driving for an owner-manager. Misclassifying it inflates business kilometres and understates personal ones.
That damages both tests simultaneously. It overstates the business percentage, which may be the only thing keeping the file above 50 percent. And it understates personal kilometres, which drives the reduced charge formula.
So a logbook that counts commuting as business does not merely contain an error. It produces a claim that fails when corrected, and the correction moves both variables in the wrong direction at once.
The exception is real but narrow. Where the home qualifies as a principal place of business, travel from it is different in character, and an owner relying on that should establish the position rather than assume it.
For everyone else the instruction is simple: the drive to the office is personal, and a logbook that says otherwise is worse than none.
If No Record Was Kept
CRA's own position, which is more nuanced than the popular version.
Its guidance states that if no record was kept or is no longer available, the employer must be able to reasonably account for the number of personal and business kilometres driven in order to use the reduced standby charge calculation. It adds that if no record is kept or is no longer available, the employee may be eligible to use a simplified standby charge calculation[1].
Three points, ours.
The absence of a logbook is not automatically fatal to the reduction. The requirement is to reasonably account for the kilometres, which is a lower standard than a contemporaneous log but is still a standard.
Reasonably accounting for kilometres means producing something: appointment records, service invoices showing odometer readings, delivery schedules, client visit records. It is reconstruction rather than nothing.
And CRA refers to a separate simplified calculation available where records are absent, whose content we did not obtain and which an employer in that position should establish.
Commentary is nonetheless right that the reduction is unlikely without a log. One source lists among common misconceptions the belief that a logbook is unnecessary, responding that without one, reductions are unlikely[2], and another that without proper logs CRA may deny the reduction[2].
Reasonable accounting is a fallback, not a plan.
The Simplified Logbook
The relief for owners who cannot face a permanent log, and its conditions.
Commentary states that CRA allows a simplified logbook method, but only after a full 12-month base-year logbook is kept. After that, a 3-month sample logbook may be used if the later year's use stays within 10 percent of the base year. If it does not, a new base year or full records are needed[3].
Another describes the same approach as maintaining the logbook for three months and projecting to the full year, after a full representative year[7].
This is genuinely useful and underused, and this is our own view.
The barrier to logbook discipline is that it feels permanent. The simplified method converts it into one demanding year followed by a quarter each year thereafter.
Two cautions on the conditions.
The base year must be full and representative. A base year distorted by an unusual event, a long absence, a temporary contract far from home, produces a projection that fails the ten percent test in ordinary years.
And the ten percent test must actually be monitored. An owner using a sample without checking whether usage has drifted may be projecting from a base year that no longer describes their driving, which is a position that fails on examination.
The practical recommendation is to start the base year at a point when the business is operating normally, and to check the sample against the base each year rather than assuming continuity.
Reimbursements And Their Deadlines
The most direct lever available, with two dates that matter.
Commentary identifies a planning point owners often miss: if you reimburse the corporation for all personal operating costs within 45 days after year end, there is no operating expense benefit. It adds that reimbursements also reduce the standby charge benefit[3].
Another states that any amount paid to the employer for personal-use operating costs reduces the operating benefit dollar for dollar, and that if the reimbursement equals or exceeds the calculated benefit the operating cost benefit drops to zero. On the standby charge, it states that payments must be made by February 14 of the following year to offset the prior-year benefit[6].
Those two deadlines are consistent for a calendar year end, since 45 days after 31 December is 14 February, which is our own observation.
Three practical points.
The operating benefit can be eliminated entirely, not merely reduced, by reimbursing all personal operating costs within the window. That is a complete answer to one of the two benefits.
The reimbursement must be actually made, which means a payment, not a journal entry recorded later. For an owner-manager this is exactly the kind of item that gets booked at the year-end close, months after the deadline.
And the amount to reimburse depends on knowing personal kilometres, which returns to the logbook. An owner without one cannot compute what to pay, so the two controls are connected.
Months Available
A variable that is genuinely within an owner's control.
The standby charge is computed by reference to the number of months the automobile was available[5], and CRA's guidance asks the employer to record the total number of days the automobile was made available during the year[1].
Commentary suggests among practical steps returning the car to the employer at year end during extended personal travel, on the basis that it reduces months available[7].
We report that suggestion and would attach a firm caution, which is ours.
Availability is a question of fact. A vehicle is not unavailable because a document says so; it is unavailable because the employee genuinely could not use it, which normally means the keys and the vehicle were returned to the employer's control.
For an owner-manager that is a difficult fact to establish, because they control both parties. Returning a car to a corporation you own, and parking it at premises you control, may not amount to much.
Where it is genuine, the saving is real and proportionate: each month of genuine unavailability removes 2 percent of cost from the benefit, being $1,200 a year per month on our $60,000 illustration.
Where it is not genuine, it is a documented assertion contradicted by the facts, which is a worse position than not claiming it.
It Matters More If You Own The Company
The point commentary makes most sharply, and it corrects the opposite assumption.
It lists among common misconceptions the belief that if I own the company, it doesn't matter, and responds: it matters more. It explains that the owner determines availability, and therefore documentation must be stronger[2].
That is exactly right and this is our own elaboration of why.
In an arm's length employment relationship, the employer has its own reasons to police vehicle use. It pays for the fuel, it wants the asset used for business, and it has no interest in overstating an employee's business mileage.
That independent interest is itself a form of evidence. Records produced by a party with something to lose are more persuasive than records produced by the person who benefits from them.
An owner-manager has no such counterparty. They decide the vehicle purchase, the availability, the usage and the record. Every input is within their control.
So the documentary standard is higher precisely because the ordinary safeguard is absent, and an owner-manager relying on a reconstructed estimate is relying on their own unverified assertion.
Commentary also frames the underlying decision well, noting that for some owner-managers corporate ownership creates unnecessary personal tax while for others it remains efficient, and that modelling is essential[2].
How It Reaches Your T4
The mechanics, which determine when the amount becomes visible.
Commentary states that both amounts are added together and reported as employment income on the T4 in Box 14 as total employment income and Box 34 as personal use of employer's automobile. The employer is responsible for calculating the benefit and remitting the appropriate CPP contributions, and because it is a non-cash benefit no EI premiums apply[6].
Two consequences, ours.
The benefit carries CPP as well as income tax, which is a further cost frequently omitted from comparisons between corporate and personal ownership.
And the amount appears at T4 time, which is after every deadline that could have changed it. The written notification for the optional operating method is due before year end. The reimbursements are due within 45 days after. By the time the number appears on a slip, none of those levers remains available.
Commentary makes a sensible suggestion on this: review the calculation annually and ask the employer what has been calculated for Box 34 before the T4 is issued[7].
For an owner-manager that means instructing whoever prepares the payroll to produce the figure in December rather than in February, when there is still time to act on it.
The Corporate Side
The deduction, which is capped and which owners assume is unlimited.
Commentary states that for purchased passenger vehicles over the ceiling, the vehicle generally lands in Class 10.1, which has a 30 percent capital cost allowance rate. It records CRA guidance confirming that a passenger vehicle acquired in 2025 that cost more than $38,000 before tax is capped at that amount plus sales taxes for Class 10.1 purposes[3].
We report the ceiling as that source states it for 2025; the figure is set annually and must be confirmed for the year of acquisition.
Commentary also notes that a flat monthly allowance is taxable[3], which is a separate trap for owners who pay themselves a car allowance instead.
The structural point, and this is our own analysis, is the asymmetry between the two sides.
The corporation's deduction is capped by reference to a ceiling. The employee's standby charge is computed on the full cost with no equivalent cap.
So on a vehicle costing well above the ceiling, the corporation deducts depreciation on a limited base while the owner is taxed on 24 percent of the whole price.
That divergence widens as the vehicle gets more expensive, and it is the arithmetic reason expensive vehicles held corporately model so poorly. Commentary puts the general principle well: tax efficiency begins with understanding both sides of the equation, corporate deduction and personal inclusion[2].
What The Auditor Actually Examines
The enquiry in practice. This section is our own analysis.
Whether a benefit was reported at all, where a corporation owns a vehicle and an owner or employee has access to it. Its absence is the first thing visible.
The logbook, tested for whether it is contemporaneous and whether it records date, destination, purpose and kilometres.
Classification of commuting, which is the most common error and moves both tests adversely when corrected.
Both reduction conditions, separately, since satisfying one does not establish the other.
Months available, and whether any claimed period of unavailability is supported by facts rather than assertion.
Reimbursements, tested for whether they were actually paid and within the deadline, rather than recorded at year-end close.
The written notification where the optional operating method was used, and whether it predates year end.
Odometer evidence from service and inspection records, which independently establishes total kilometres and can be compared against the log.
That last item deserves emphasis. Service invoices routinely record odometer readings and are held by third parties. A logbook whose total kilometres do not reconcile to them is contradicted by evidence the taxpayer did not create.
What Records Survive
A contemporaneous logbook recording date, destination, purpose and kilometres for each business trip, with total odometer readings at the start and end of the year.
A full base-year logbook if the simplified method is to be used later, kept in a representative year.
An annual check of the sample against the base year, evidencing that usage remains within ten percent.
The purchase or lease documentation establishing cost or monthly payments excluding insurance.
Proof of reimbursement payments, with dates, showing they fell within the applicable window.
The written notification for the optional operating method, dated before year end.
Service and inspection invoices showing odometer readings, retained as corroboration rather than discarded.
Evidence supporting any principal place of business position, where home-to-office travel is treated as business.
What To Do
Keep the logbook. On our figures it is worth roughly $4,644 of tax in one year on a $60,000 vehicle with 5,000 personal kilometres, and about $23,222 over five.
Stop counting the commute as business. CRA normally treats home-to-office driving as personal, and misclassifying it damages both reduction tests at once.
Check both conditions, not one. The reduction needs business use above 50 percent and personal driving under 1,667 kilometres a month.
Model the holding period, not just the purchase. The standby charge is 2 percent of original cost forever, so on our figures five years produces 120 percent of the car's cost in taxable benefit.
Reimburse personal operating costs within the window. Doing so fully is reported to eliminate the operating benefit entirely, and 45 days after a December year end is 14 February.
Make reimbursements as actual payments, not as entries recorded at the year-end close months later.
Run the optional operating method calculation in November. The written notification is due before year end, and on our illustration the option only helps above roughly 21,000 personal kilometres.
Ask for the Box 34 figure in December. By the time it appears on a T4 every lever that could change it has expired.
Start a proper base year so you can use the three-month sample afterwards. Choose a representative year and check the ten percent test annually.
Model corporate against personal ownership, and revisit it. An arrangement that works over three years can be clearly poor over eight, and the corporate deduction is capped while the standby charge is not.
The Limits Of This Analysis
Several caveats matter. This is not tax advice; whether a vehicle should be held corporately turns on specific numbers and requires modelling. Everything is stated as verified in August 2026 and requires confirmation; prescribed rates and capital cost ceilings in this area are set annually and change, and the per-kilometre rate and the vehicle ceiling reported here come from commercial sources and should be taken from CRA's own publication for the relevant year. We have not verified any statutory provision against the Act and the paragraph references are as commentary cites them. We accessed CRA's guidance for record-keeping requirements but did not obtain the content of the simplified standby charge calculation it refers to. The reduced standby charge formula, the optional operating method conditions, the reimbursement deadlines, the simplified logbook conditions and the T4 reporting mechanics are all reported from commercial and professional commentary rather than verified against CRA's own text. The suggestion regarding returning a vehicle to reduce months available is reported from commentary and we have attached our own caution about it. All arithmetic is our own, applies reported rates and an assumed marginal rate to a hypothetical vehicle, ignores provincial variation, CPP, and any employer-side cost, and is illustrative only; the cumulative figures assume a full standby charge throughout, which is the position where the reduction is unavailable or unclaimed. The non-declining analysis, the two-conditions illustration, the per-kilometre framing, the commuting arithmetic, the observation about the absent arm's length counterparty and the audit examination structure are our own. This article does not address motor vehicle allowances, employee-owned vehicles used for business, GST/HST input tax credits and the associated benefit remittance, automobiles used by shareholders who are not employees, or the treatment on disposition of a Class 10.1 vehicle.

Prescribed rates and capital cost ceilings are set annually and must be confirmed from CRA's own publication for the relevant year. Statutory provisions have not been verified against the Act.
