Vehicle CCA: Class 10 vs 10.1 vs 54 (2026)

If you bought a vehicle for your business in 2026, the first-year write-off is far larger than it was two years ago — and larger than most published guidance still says.

A zero-emission passenger vehicle now gets a 100% first-year deduction, capped at $61,000 before tax. A conventional vehicle gets an effective 45% in year one, with the half-year rule suspended. Both measures were carried by Bill C-15, the Budget 2025 Implementation Act, No. 1, which received Royal Assent on March 26, 2026.

That date matters, because a lot of what you’ll read online was written while these were still proposals. The CRA’s own page on depreciable property still frames the zero-emission reinstatement with “under proposed changes” wording — its editorial text hasn’t caught up with the legislation. The measures are law.

The rest of this guide is the part that hasn’t changed: how to tell whether your vehicle is Class 10, Class 10.1, Class 54 or Class 55; why that classification decides whether you ever see a terminal loss; and how the deduction is actually calculated on Form T2125.

Key takeaways

• 2026 first-year rates: Class 54 zero-emission passenger vehicle 100% (capped at $61,000 before tax); Class 10 and 10.1 conventional vehicles 45% effective, half-year rule suspended. Both enacted by Bill C-15, Royal Assent March 26, 2026.
• Class 10 vs 10.1 turns on cost before GST/HST/PST. At or below $39,000 for a 2026 acquisition → Class 10. Above → Class 10.1.
• Class 10.1 has no recapture and no terminal loss. This is the single most-misstated rule in Canadian vehicle tax content.
• The ceiling is fixed by the year you acquired the vehicle and never rises afterward.
• CCA is discretionary. You can claim any amount from zero up to the maximum. Claiming the maximum is often the wrong move.
• CCA is calculated on the whole class in Area A, then reduced by the personal portion before it reaches line 9936.

What capital cost allowance is

You can’t deduct the cost of a vehicle in the year you buy it — at least, not as an ordinary expense. A vehicle is a capital asset that produces income over several years, so the Income Tax Act makes you deduct it gradually. That gradual deduction is capital cost allowance.

Each class of asset has its own rate, applied on a declining-balance basis. Vehicles sit at 30% (Class 55 is the exception at 40%). Declining balance means you take 30% of what’s left, not 30% of the original cost, so the deduction shrinks each year and the asset is never quite written off.

The unclaimed remainder is the undepreciated capital cost, or UCC. It’s the number that carries forward.

Two things about CCA surprise people. First, it’s optional — you may claim any amount between zero and the maximum, and whatever you don’t claim stays in the pool for a future year. Second, the first-year rules are where almost all the money is, and they’re the part that changed in 2026.

The 2026 first-year rates

Where the 45% comes from. Normally the half-year rule limits a first-year claim to half the class rate — 15% on a 30% class. Under the reinstated Accelerated Investment Incentive, the half-year rule is suspended and the allowance is enhanced to one and a half times the class rate: 30% × 1.5 = 45%. Three times what you’d otherwise get.

Where the 100% comes from. The enhanced first-year allowance for zero-emission vehicles was originally scheduled to fall to 55% for a vehicle available for use in 2026. Bill C-15 reinstated the full write-off for zero-emission vehicles acquired after 2024, on this schedule:

The conventional-vehicle incentive follows the same window: full enhancement for property acquired after 2024 and available for use before 2030, then a phase-out through 2033.

Which class is your vehicle?

Work through this in order.

1. Is it a zero-emission vehicle? If yes, and it’s a passenger vehicle, it’s Class 54. If it’s a zero-emission vehicle that would otherwise be Class 16 — a taxi, a short-term rental vehicle, or a heavy freight truck rated above 11,788 kg — it’s Class 55.

2. Is it a passenger vehicle at all? Work trucks and vans meeting the CRA’s seating and use tests are ordinary motor vehicles, and no ceiling applies to them. Our T2125 vehicle expenses guide has the full classification table, including the rule for pick-ups servicing remote work sites.

3. What did it cost before tax? This is the Class 10 / Class 10.1 test, and the CRA is specific: use the cost of the vehicle before you add GST/HST or PST.

• $39,000 or less (2026 acquisition) → Class 10
• More than $39,000 → Class 10.1

A $38,900 car is Class 10. A $39,100 car is Class 10.1. One hundred dollars of sticker price changes which rules govern the vehicle for as long as you own it.

Class 10 and Class 10.1 behave differently

Class 54 sits in between: it has a ceiling like Class 10.1, but it is pooled — Class 54 does not create a separate class for each vehicle — and it does have recapture and terminal loss.

The ceilings, by year of acquisition

The ceiling that applies to your vehicle is the one in force when you acquired it. It does not rise later.

All figures are before tax. If you bought in 2022 and you’re filing for 2026, your Class 10.1 capital cost is still $34,000.

How GST/HST enters the capital cost

The ceiling is a before-tax figure, but the capital cost you actually depreciate includes sales tax calculated on the ceiling — not on the higher price you paid.

Buy a $47,000 car in Ontario in 2026. Your Class 10.1 capital cost is:

Not $47,000, and not $53,110. The $8,000 of price above the ceiling is invisible to the tax system, permanently.

If you’re GST/HST-registered, input tax credits change this further — see the section below.

Area A: how the calculation actually runs

CCA is computed in Area A of Form T2125 and the result lands on line 9936.

Area A runs across nineteen columns. The ones that carry the work:

Two things about this structure catch people out.

CCA is computed on the full class, then reduced. Column 18 is the CCA for the whole class, ignoring how much of your driving was personal. You subtract the personal portion afterward, and only the business share reaches line 9936. But column 19 — your closing UCC — is reduced by the full column 18 amount, personal share included. The personal portion of depreciation is gone. It never comes back.

Class 10.1 vehicles are listed separately. One line each. Class 10 assets share a line.

Dispositions go in Area D, and the proceeds you enter there cannot exceed the capital cost.

Worked example: Devon, Class 10 with the incentive

Devon runs a home-inspection business in Calgary. In March 2026 he buys an SUV for $36,500 before tax. Alberta charges GST only, so he pays $1,825 in GST on top.

Class: $36,500 is below $39,000, so Class 10. No ceiling applies.

Devon is GST-registered, and his commercial use is 72% — between 10% and 90%. That means no upfront input tax credit on the purchase. Instead he claims a credit each year equal to the tax fraction of the CCA he deducts. So the GST stays in his capital cost for now.

Capital cost: $38,325.

What the incentive is worth to him. Under the half-year rule his first-year claim would have been $38,325 × 15% = $5,749 at class level, or $4,139 after proration. The incentive gives him $8,278 more deduction in year one.

Input tax credit. 5/105 × $12,417 = $591. That credit reduces his UCC in 2027, bringing it to $20,488.

Cash value. Devon’s net business income is $92,000 before the deduction, $79,583 after. Both sit in Alberta’s 10% band and the federal 20.5% band — a 30.5% combined marginal rate.

Note how little CPP contributes. Most of Devon’s deduction comes off income above the $85,000 second earnings ceiling, where no further CPP is payable. A deduction’s CPP value depends entirely on where your income sits.

Worked example: Théo, Class 54 and the 100% write-off

Théo is a self-employed renovation designer in Ottawa. In May 2026 he buys an electric vehicle for $68,000 before tax, and uses it 65% for business. Ontario charges 13% HST.

Class: zero-emission passenger vehicle → Class 54, ceiling $61,000.

The entire capital cost is available in year one. His business share of the maximum would be $68,930 × 65% = $44,805.

But he shouldn’t claim all of it. Théo’s net business income before CCA is $96,000. Deducting $44,805 would drag his income down to $51,195 — and the last stretch of that deduction would be saving him tax at 19.05%, the lowest combined Ontario rate, when the same deduction held back a year could be worth 29.65%.

So he claims less. He takes $57,657 at class level, giving a business deduction of $37,477 and landing his income at $58,523 — the bottom of the 20.5% federal band. The remaining $11,273 of capital cost stays in the pool and carries forward.

Input tax credit: 13/113 × $37,477 = $4,312, which reduces his 2027 UCC to $6,961.

That CPP adjustment is where most calculators get it wrong. Self-employment CPP isn’t uniformly deductible. Roughly 58% of the base contribution is deducted from income at your marginal rate; the rest generates a non-refundable credit worth only the lowest rate — 14% federally plus 5.05% in Ontario. CPP2 is fully deductible. Reducing your income reduces all of those too, and netting it out costs Théo $730 of the headline $2,745.

Selling, trading in, and changing use

Class 10: recapture and terminal loss

Proceeds of disposition — capped at the original capital cost — come off the pool. Then:

• If the pool goes negative and you still own property in the class, the negative amount is recapture, added to income on line 8230, “Other income.”
• If the class is empty and a positive balance remains, that’s a terminal loss, deducted on line 9270, “Other expenses.” A terminal loss requires the class to be emptied — you cannot claim one while other Class 10 assets remain.

A trade-in counts as proceeds equal to the trade-in allowance.

Class 10.1: neither

No recapture. No terminal loss. Sell your Class 10.1 vehicle for more than its UCC and nothing is added back; sell it for less and nothing is deducted. This is the rule most often got wrong, and it cuts both ways — it’s protection on a vehicle that held its value, and a dead loss on one that didn’t.

You do get one consolation: a half-year’s CCA in the year you dispose of a Class 10.1 vehicle you owned at the end of the previous year. Fifteen percent, in a year you no longer own the car by December.

Class 54: recapture, with a twist

Class 54 has recapture and terminal loss like Class 10. But where the capital cost was capped, proceeds are prorated by the ratio of the ceiling to what you actually paid.

Théo paid $68,000 before tax and was capped at $61,000. If he sells for $40,000, the proceeds applied against his pool are:

$40,000 × ($61,000 ÷ $68,000) = $35,882

The system caps what you can depreciate, so it also discounts what you have to give back.

Changing use

Moving a vehicle between personal and business use is a deemed disposition and reacquisition at fair market value. Going business-to-personal, you’re treated as having sold at FMV, which can trigger recapture. Going personal-to-business, your CCA base is generally the lesser of cost and FMV, with an adjustment so that an accrued gain isn’t quietly converted into depreciation.

Ceasing business is a deemed disposition too.

Lease or buy?

The tax mechanics differ more than most comparisons admit.

Chart C’s cap isn’t simply $1,100 a month. The chart takes the lesser of two figures: one built from the monthly limit, grossed up for tax and prorated by days; the other tied to the manufacturer’s suggested list price, so that an expensive lease is restricted further. If your refundable deposits total more than $1,000, you can’t use Chart C at all.

The 2026 first-year rules tilt the comparison toward buying more than they have in years — a 100% write-off on a zero-emission vehicle has no leasing equivalent. That’s a cash-flow question as much as a tax one, and it’s worth running both with your accountant before signing.

GST/HST and input tax credits

If you’re registered, the tax you recover changes your CCA base.

An input tax credit you claim reduces your UCC in the following year. It isn’t free money on top of the deduction — it’s a recovery that shrinks the base you depreciate.

For a corporation the middle threshold is more than 50% rather than 90%, which is one of several reasons the incorporation question changes the arithmetic here.

Quebec

Quebec is fully harmonised with the federal rules on vehicle CCA. Same classes, same 30% and 40% rates, same 2026 ceilings — $39,000 for Class 10.1 and $61,000 for Class 54 — and Quebec mirrors the reinstated Accelerated Investment Incentive on the same 2025–2029 window.

Reporting differs. Capital cost allowance goes on line 240 of Form TP-80-V, Business or Professional Income and Expenses, with motor vehicle expenses at line 220. Revenu Québec’s Capital Cost Allowance Guide, TPW-130.G-V, is the working reference; guide IN-155-V covers business and professional income generally.

One Quebec-specific trap. The Roulez vert rebate — up to $2,000 on a new eligible electric vehicle and $1,000 on a used one, with the programme ending December 31, 2026 — is government assistance. It reduces your capital cost before you calculate CCA. Because it’s provincial rather than federal assistance, taking it doesn’t disqualify the vehicle from Class 54. But claiming CCA on the full purchase price after receiving a rebate overstates your deduction.

Quebec’s historical “additional capital cost allowance” never applied to vehicles — it covered computer and manufacturing equipment, and expired for property acquired after December 3, 2018. If you see it referenced in a vehicle context, that page is wrong.

What gets a CCA claim reduced or denied

Record-keeping is a statutory obligation under section 230 of the Income Tax Act. The claim stands on your records, not on your recollection.

The technical failures:

• Claiming CCA on the full cost of a vehicle above the ceiling. The excess isn’t depreciable. Ever.
• Putting a vehicle in the wrong class — usually treating a Class 10.1 vehicle as pooled Class 10, which produces a terminal loss that doesn’t exist.
• Claiming recapture or a terminal loss on Class 10.1. Neither applies.
• Failing to prorate proceeds on a Class 54 or capped vehicle at disposition.
• Claiming the full sales tax as an input tax credit rather than the amount on the capped cost, or claiming an upfront ITC at under 90% commercial use.
• Ignoring a rebate or other government assistance that should have reduced the capital cost.

And the failure that dwarfs all of them:

• No logbook. Every figure above is multiplied by a business-use percentage. Without date, destination, purpose and kilometres per trip — plus odometer readings at the start and end of the fiscal period — that percentage is a number you asserted rather than a number you can support.

Vague destinations do the same damage as no log at all. “Various clients” and “around town” are not records. Suspiciously round monthly figures invite the question of where they came from.

How automatic tracking fits

CCA amplifies the record-keeping problem rather than changing it.

The stakes rise with the purchase. A percentage that was worth a few hundred dollars against fuel and insurance is now multiplying a five-figure first-year write-off. A ten-point error in your business-use figure on Théo’s vehicle is worth about $6,900 of deduction.

The ratio still needs the denominator. Business kilometres alone tell you nothing. You need total kilometres, which means the personal trips get logged too.

And it compounds across years. Your UCC carries forward, so a percentage you can’t defend in year one is a percentage you’re still relying on in year four.

EveryLastMile, an iOS mileage tracking app, detects drives on-device using your iPhone’s motion and location sensors, so trips are captured without you starting anything. Each is classified business or personal with a swipe, which produces the ratio rather than just the numerator. Every trip carries the date, route, distance and business purpose, and a CSV export hands the whole year to your accountant in one file.

Processing happens on your phone. For a record you’re required to keep six years — and longer where a base-year logbook supports later years — that’s worth something.

Frequently asked questions

What's the difference between Class 10 and Class 10.1?

Cost. A passenger vehicle costing $39,000 or less before tax (2026 acquisition) goes in Class 10, which is pooled and has recapture and terminal loss. Above $39,000 it goes in Class 10.1, which uses a separate class per vehicle, caps the depreciable cost at the ceiling, and has neither recapture nor terminal loss.

What is the Class 10.1 cost limit for 2026?

$39,000 before tax, for vehicles acquired on or after January 1, 2026. It rose from $38,000. The ceiling that applies to your vehicle is the one in force in the year you acquired it.

Is the cost threshold measured before or after GST/HST?

Before. The CRA is explicit that you use the cost of the vehicle before adding GST/HST or PST to determine the class. Sales tax then enters the capital cost, but calculated on the ceiling rather than on what you actually paid.

What is Class 54, and what is the 2026 ceiling?

Class 54 holds zero-emission passenger vehicles that would otherwise be Class 10 or 10.1. The ceiling is $61,000 before tax and the rate is 30%. Unlike Class 10.1, Class 54 is pooled and does have recapture and terminal loss.

Can I write off 100% of an electric vehicle in the first year in 2026?

Yes, up to the $61,000 before-tax ceiling, for a Class 54 vehicle acquired between 2025 and 2029 and available for use. The write-off is then reduced by your personal-use portion. Whether you should claim the full amount is a separate question — CCA is discretionary.

Was the enhanced zero-emission CCA actually enacted, or is it still proposed?

Enacted. Bill C-15, the Budget 2025 Implementation Act, No. 1, received Royal Assent on March 26, 2026, carrying both the reinstated 100% zero-emission first-year allowance and the reinstated Accelerated Investment Incentive. Some published guidance — including CRA web page wording — still describes these as proposed.

What is the half-year rule, and does it still apply in 2026?

Normally it limits a first-year CCA claim to half the usual amount. For vehicles qualifying under the reinstated Accelerated Investment Incentive in 2026, it's suspended, and the first-year allowance is one and a half times the class rate instead — an effective 45% on a 30% class.

Does Class 10.1 have recapture or a terminal loss?

No, neither, unless the vehicle is designated immediate expensing property. Sell it above its undepreciated capital cost and nothing is added to income; sell it below and nothing is deductible.

How does my business-use percentage affect my CCA claim?

It reduces what you deduct but not what you depreciate. CCA is computed on the full class, and only the business share reaches line 9936 — but your closing UCC drops by the full amount, personal share included. Depreciation attributable to personal use is permanently lost.

Do I have to claim the maximum CCA?

No. CCA is discretionary. You may claim any amount from zero to the maximum, and the unclaimed portion stays in the pool. Because a deduction is worth your marginal rate, claiming enough to collapse your own tax bracket wastes part of it.

Should I lease or buy for tax purposes?

Leasing gives you deductible payments capped at $1,100 a month for 2026. Buying gives you CCA on a capped cost plus interest capped at $350 a month, heavily front-loaded under the current first-year rules. The 2026 rates favour buying more than in recent years, particularly for a zero-emission vehicle, but it's a cash-flow decision as much as a tax one.

How does the GST/HST input tax credit work on a business vehicle?

For an individual or partnership at 90% or more commercial use, you claim a full ITC limited to the tax on the capital-cost ceiling. Between 10% and 90%, there's no upfront credit — instead you claim the tax fraction of the CCA you deducted each year. Any ITC claimed reduces your UCC the following year.

How do I report vehicle CCA in Quebec?

On line 240 of Form TP-80-V, with motor vehicle expenses at line 220. Quebec is fully harmonised with the federal classes, rates and ceilings. Guide TPW-130.G-V covers capital cost allowance and IN-155-V covers business and professional income.

Does the Roulez vert rebate affect my CCA?

Yes. It's government assistance and reduces your capital cost before you calculate CCA. Because it's provincial rather than federal, it doesn't disqualify the vehicle from Class 54. The programme ends December 31, 2026.

What records does the CRA require, and what triggers a review?

For each business trip: date, destination, purpose and kilometres driven, plus odometer readings at the start and end of each fiscal period. Keep them six years. Vague destinations, implausibly round figures and missing odometer readings are the common triggers.
