Capital Cost Allowance is usually sold to landlords as "free money you're leaving on the table." It isn't free. CCA on a rental property in Ontario is closer to a loan from the CRA — one you repay, often at a higher rate, the day you sell.
It's the most misunderstood line on a rental return. CCA is optional, it can't create a loss, and every dollar you claim can come back as fully taxed "recapture." Claimed blindly, it can even cost you your Principal Residence Exemption. So the real question isn't just how to claim it — it's whether you should.
This guide explains how CCA actually works for an Ontario rental — the 4% Class 1 rate, the half-year rule, the land split, the appliance classes — and then the part most articles skip: the traps, and the situations where claiming it is a mistake. It's general information, not tax advice; talk to a CPA about your own situation and verify the details with the CRA.

Capital Cost Allowance is the CRA's tax-depreciation system. It lets you deduct a portion of a depreciable asset's cost each year against your rental income, on the logic that buildings and equipment wear out over time. The calculation uses the declining-balance method: the rate is applied to the remaining undepreciated capital cost (UCC), not the original price, so the claim shrinks a little every year and a building never fully depreciates through ordinary claims.
Most residential rental buildings acquired after 1987 fall into Class 1, which depreciates at 4% a year — slow by design, because the CRA expects buildings to last decades. CCA is claimed in Area A of Form T776, the same statement where you report your rental income and expenses (and note that rental income isn't self-employment, so CPP doesn't apply). One distinction worth getting right before you go further: a current repair — fixing what's already there — is deducted in full the year you spend it, while a capital improvement is added to the building and depreciated through CCA. That line matters, and we cover it in the maintenance standards guide.
The Rules Everyone Misses
Four rules trip up almost every landlord who claims CCA for the first time.
First, land isn't depreciable — CCA applies to the building only, so you have to split the purchase price between land and building using the purchase agreement, an appraisal, or municipal assessment ratios. A sloppy split is an audit flag. Second, the half-year rule: in the year you acquire the property you can claim on only 50% of the addition, so a Class 1 building's first-year rate is effectively about 2%. Third — and this is the one that surprises people — CCA cannot create or increase a rental loss. It can reduce your net rental income to zero, but not a dollar below. If your income after other expenses is $8,000, your maximum CCA that year is $8,000, even if your entitlement is higher; the unused portion simply carries forward. (You also combine the net income or loss from all your rental properties before claiming.) Fourth, CCA is optional — you can claim any amount from zero up to the maximum, which is exactly why skipping it in a loss year, or a year you'd rather not, is a legitimate move. As a rough feel for the numbers: a $350,000 building generates about $14,000 of CCA in a full year at 4%, but only around $7,000 in year one under the half-year rule.
The Three Traps
Here's the part the "free money" articles leave out. Claiming CCA has three consequences that can cost you more than the deduction saved.
Trap one is recapture, and it's the big one. When you sell for more than the building's UCC, all the CCA you claimed over the years is "recaptured" — added back to your income in the year of sale and taxed fully, at 100% inclusion, at your marginal rate. Compare that to a capital gain, which is taxed at the 50% inclusion rate. So if you'd never claimed the CCA, you'd simply have a larger capital gain taxed more lightly. CCA is a deferral, not a permanent deduction — and on sale you can face the double hit of recapture plus a capital gain on the appreciation above your cost.
Trap two is the principal-residence trap, and it catches house-hackers especially. Claiming CCA on a property — or on the rented portion of your own home, like a basement suite — can make that portion ineligible for the Principal Residence Exemption from that point forward, exposing it to capital-gains tax when you sell. If the place might ever become your home, or your child's, most advisors say don't claim CCA at all, because the exemption is usually worth far more than the annual deductions. Trap three is a terminal loss — the flip side. If you sell the building for less than its UCC, the shortfall is a terminal loss, deductible against your income in the year of sale. It's rare given how real estate tends to appreciate, but it's also a planning tool: electing to put each building in its own separate Class 1 pool keeps each property's recapture or terminal loss independent, where a single pooled class can't throw a terminal loss until every building in it is sold.
To be fair to the other side: some investors argue that the tax CCA defers, if reinvested well, can out-earn the eventual recapture cost. That's a real strategy — but it depends on discipline and on your assumptions about future tax rates, which is exactly the kind of judgment call to run past an accountant.
The Decision: Claim or Skip?
Put it together and CCA becomes a decision, not a reflex.
Claiming often makes sense when you have positive net rental income to absorb the deduction, you plan to hold for the long term, you expect to be in a lower tax bracket when you eventually sell (say, in retirement), and the property is a pure investment you won't convert to a home. Skipping is often smarter when the place might become a principal residence for you or a child, when you may sell soon (recapture would land at today's higher rate), or when you're already running a rental loss and can't claim it anyway. When you're genuinely unsure, skipping is the conservative default — you preserve the UCC and can always claim later.
If you do claim, a couple of Pro moves are worth knowing. Asset segregation means splitting fast-depreciating components out of the 4% building pool — appliances go in Class 8 at 20%, HVAC and heat pumps can qualify for Class 43 at 30%, a management vehicle's business-use share in Class 10, computers in Class 50 at 55% — which front-loads deductions when you want cash flow. And if you're building new, there's a time-sensitive incentive: a new eligible purpose-built rental constructed between April 16, 2024 and December 31, 2030 can qualify for an accelerated 10% CCA rate rather than 4% (confirm eligibility with your accountant). Whatever you do, do it right — split land and building defensibly and keep the documentation, apply the half-year rule, track your UCC year over year, keep every receipt, and claim it in Area A of the T776 after combining all your properties' income.

Key Takeaways
- CCA depreciates the building (not the land) at 4% a year — half that in year one under the half-year rule.
- It can't create or increase a rental loss, and it's optional — claim zero up to the maximum.
- Recapture claws back the CCA you claimed at 100% inclusion on sale, versus 50% for a capital gain.
- Claiming CCA can void your Principal Residence Exemption — a real risk on a home or basement suite.
- Claim when you hold long-term with positive income and no conversion plan; skip when a home, a near-term sale, or a loss is in the picture.
Conclusion
CCA lets you depreciate the building (not the land) at 4% a year, half that in year one, and only down to zero rental income — never into a loss. It's optional, and it's a deferral: claim it and recapture can claw it back at 100% on sale, and on a would-be principal residence it can cost you the exemption entirely. So the smart question isn't "how much can I claim?" but "does claiming fit my income, my hold horizon, and my exit?"
Run the decision rather than the autopilot. For a long-hold investor with positive income and no plans to move in, CCA is a genuine tool; for a future home or a near-term sale, skipping is often the smarter play.

Frequently Asked Questions
What is CCA on a rental property?
Capital Cost Allowance is the CRA's tax-depreciation system. It lets you deduct a portion of your building's cost each year against rental income. Most residential buildings are Class 1 at 4% on a declining-balance basis, and it's claimed on Form T776.
Can CCA create a rental loss in Canada?
No. CCA can reduce your net rental income to zero, but it can't create or increase a rental loss. If your income after other expenses is $5,000, your maximum CCA that year is $5,000; any unused entitlement carries forward.
Do I have to claim CCA?
No — CCA is optional. You can claim any amount from zero up to the maximum in a given year, and many landlords skip it in loss years or when they want to avoid future recapture.
How is CCA recapture taxed when I sell?
If you sell for more than the undepreciated capital cost, the CCA you claimed is recaptured and added to your income in the year of sale, taxed fully at your marginal rate — unlike a capital gain, which is taxed at the 50% inclusion rate.
Should I claim CCA on a basement apartment in my home?
Usually not. Claiming CCA on the rented portion of your home can make that portion ineligible for the Principal Residence Exemption, exposing it to capital-gains tax on sale — often far more costly than the deduction. Ask a CPA first.
Is land depreciable for CCA?
No. Only the building is depreciable. You must split the purchase price between land and building — using the purchase agreement, an appraisal, or municipal assessment ratios — and claim CCA on the building portion only.
