Rental Property CCA Calculator Canada

Capital cost allowance is Canada's version of depreciation, and the first thing to understand is that it is optional. Unlike the US, where the tax authority calculates recapture on depreciation you were merely entitled to take, the CRA only recaptures what you actually claimed. That single difference turns CCA from a box you tick into a decision you make — and revisit — every single year.

The mechanics. Rental buildings normally fall in CCA Class 1, at 4% declining balance — not straight line. Land is carved out first, since it is not depreciable. The building cost becomes your undepreciated capital cost (UCC). Each year's CCA is 4% of the opening UCC, and the UCC falls by whatever you claim, so every year's claim is smaller than the one before. In the year you acquire the property the half-year rule applies: you may claim CCA on only one half of the net addition, so a first-year claim is effectively 4% of half the building cost.

The constraint that governs everything: CCA cannot create or increase a rental loss. It can only reduce your net rental income to zero. If the 4% formula produces $9,000 of CCA but your net rental income before CCA is $4,000, you may claim $4,000 — not a dollar more. This is why this calculator asks for your net rental income before CCA and caps the claim against it. The denied portion is not lost: it stays in the UCC pool, undiminished, and is available in a future year when the property turns a profit. Many leveraged Canadian rentals run at or near zero net income in the early years precisely because of mortgage interest, which means the CCA question is often moot until the mortgage is well into paydown.

Why many Canadian investors deliberately don't claim CCA. Every dollar of CCA you claim is recaptured into your income in the year you sell, taxed at your full marginal rate — not at the capital-gains rate. So the trade is: shelter income at your marginal rate today, then add it all back at your marginal rate in the sale year, potentially as a single lump that pushes you into a higher bracket. If you expect meaningful appreciation, or a high-income year at sale, or you simply want a clean disposition, forgoing CCA and leaving the UCC untouched is a common and entirely legitimate strategy. Because CCA is optional here, choosing not to claim genuinely avoids the recapture — which is precisely the opposite of the US “allowed or allowable” rule. Note also that recapture is separate from your capital gain, which is taxed at the 50% inclusion rate (the proposed increase to 66.67% was cancelled in March 2025).

To see how the CCA decision sits alongside the rest of the deal, run the numbers through the rental property ROI calculator, and model the disposition with the capital gains tax calculator.

This tool is an educational estimate, not tax advice. Whether to claim CCA depends on your income, hold period, and plans for the property — consult a CPA or tax professional before you file or sell.
