Should You Claim Capital Cost Allowance on Your Rental Property?

Rental property owners must report annual rental income and expenses on their tax returns, and they should also track the adjusted cost base (ACB) of the property. The ACB can rise with capital improvements and renovations and is used to calculate the capital gain when the property is eventually sold.

Two related tax concepts that are important for landlords to understand are undepreciated capital cost (UCC) and capital cost allowance (CCA). These determine how much of the property’s cost can be depreciated for tax purposes, how that depreciation reduces future deductions, and how it affects tax when the property is sold.

What is UCC?

The Canada Revenue Agency treats the capital cost of an asset as what you paid to acquire it, including reasonable associated costs such as delivery charges, GST/HST, and provincial sales taxes where applicable. For rental real estate, capital cost can also include acquisition costs like legal fees and land transfer tax.

Undepreciated capital cost (UCC) is the remaining balance of that capital cost that has not yet been claimed as CCA. Each year, the CCA you claim reduces the UCC. Keeping accurate annual records of UCC is essential because it determines the basis for future CCA calculations and the amount that may be recaptured when you sell the property.

What is CCA?

Capital cost allowance (CCA) is the depreciation deduction you can claim on certain capital assets for tax purposes. For rental real estate, you can claim CCA on the building but not on the land. The amount you can claim is a percentage of the UCC, applied on a declining-balance basis. Typically, the first year’s claim is limited by the “half-year rule,” which often results in a lower initial rate (commonly up to 2% in the acquisition year), with higher percentages (frequently around 4%) available in subsequent years. As you claim CCA, the property’s UCC is reduced accordingly, so it’s important to update UCC annually.

Because land is not depreciable, you must allocate the total purchase price between land and building when you acquire a rental property. A condominium purchase often has a relatively small land component, which means a larger proportion of the purchase price can be subject to CCA. For properties on large parcels, the land portion can be substantial and reduces the amount available for CCA. A professional appraisal can provide a reliable allocation, but for tax purposes you may use a reasonable estimate supported by documentation.

Why claim CCA?

Claiming CCA reduces net rental income and lowers current tax payable. The actual tax savings depend on your marginal tax rate and whether the property is held personally or in a corporation. For individuals, CCA can reduce tax by roughly 20% to 50% depending on personal circumstances and province. Corporations generally realize tax savings around 50% from CCA because of different corporate tax structures.

How much CCA should you claim?

You may only claim CCA up to the point where your net rental income becomes zero. You cannot use CCA to artificially create or increase a rental loss for tax purposes. Because of this rule, the maximum CCA you can claim may vary year to year based on changes in rental income and other deductible expenses. Joint owners, such as spouses, can allocate and claim different amounts of CCA proportional to their ownership shares.

Whether you should claim CCA depends on your present and anticipated future tax situation. If your current marginal tax rate is high and you expect similar rates in the future, claiming CCA generally offers a tax deferral benefit. Conversely, if you have a low current tax rate and expect to be taxed at a higher rate later—particularly if you plan to sell in the near term—claiming CCA can cause a larger tax bill later because of recapture and capital gains treatment.

Calculating recapture

When you sell a rental property, you must determine the total CCA previously claimed on the property. That historical CCA can be “recaptured” and added to your taxable income in the year of sale if the proceeds exceed the remaining UCC, creating a tax liability. This potential recapture is a key reason some owners choose not to claim CCA during ownership, particularly if they expect to sell soon or foresee higher future tax rates.

For many property owners, claiming CCA is a timing decision: you weigh current tax savings against the likelihood and size of future recapture and capital gains taxes. Corporations often claim CCA to benefit from tax deferral, since corporate tax structures and expected future rates differ from those of individuals. Individuals with modest current income who anticipate a larger tax hit at sale should consider limiting CCA claims and consult a tax professional to model likely outcomes.
