Understanding these two categories of expenses can save you thousands of dollars in taxes — here's how to tell them apart without being an accountant.
April 2026
You just replaced the flooring in one of your units. Your water heater broke and you replaced it. You repainted the entryway. And now you're wondering: can I deduct all of this this year? The answer depends on a single distinction — and misunderstanding it can cost you.
In rental taxation, every expense belongs to one of two categories: OPEX (operating expense, 100% deductible immediately) or CAPEX (capital expenditure, to be depreciated over several years). Distinguishing them correctly means optimizing your taxes. Confusing them means risking a retroactive CRA assessment with interest and penalties.
The good news: it doesn't have to be complicated. Here's how to navigate it with concrete examples for your plex or cottage, without accounting jargon.
An operating expense (OPEX) aims to keep your property in its current state. You're fixing what's broken, maintaining what works. It's 100% deductible in the year you incur it.
Typical OPEX examples:
A capital expenditure (CAPEX) improves your property: it increases its value, extends its useful life, or substantially improves its quality. You don't deduct it all at once — it's depreciated over several years.
Typical CAPEX examples:
The CCA is the tax mechanism that lets you recover the cost of a real estate investment over several years — instead of deducting it all at once, or not deducting it at all.
Think of it this way: your building, your fridge, your furniture — they wear down over time. The CRA recognizes this wear and allows you to deduct it from your rental income each year, as a percentage of the asset's cost.
Two important things to know from the start: The CCA is optional — you're not required to claim it every year. It applies only to your building — not the land, which doesn't wear out.
The CRA groups your assets into 'classes', each with its own annual rate. The faster an asset wears out, the higher the rate.
| Class | What It Covers | Annual Rate |
|---|---|---|
| Class 1 | Concrete, brick, stucco buildings (typical plex) | 4% |
| Class 6 | Wood-frame buildings (cottage, shed) | 10% |
| Class 8 | Furniture, appliances, equipment | 20% |
| Class 10 | Vehicle used for rental property management | 30% |
| Situation | OPEX or CAPEX? | Why |
|---|---|---|
| Patching a few shingles after a storm | OPEX | One-time repair, no extension of useful life |
| Replacing 60% or more of the roof | CAPEX | Substantially extends the useful life |
| Replacing a broken window (like-for-like) | OPEX | Restoration, not an improvement |
| Replacing all windows | CAPEX | Improvement to the entire building |
| Water heater replaced with identical model | OPEX | Maintenance of condition, not an improvement |
| Upgrade to a high-efficiency water heater | Partial CAPEX | The improvement portion is capitalized |
Every year you claim CCA, the CRA considers your building to be worth a little less on paper. That's intentional — it's exactly why you make the deduction. The problem arises at resale.
If you sell for more than what the CRA considers your building to be worth, it says: 'You deducted too much in prior years — we're taking the difference back as tax.' This is what's called recapture of depreciation.
🛠️ Concrete example: you purchased a plex. The building portion is worth $450,000. After 10 years of CCA, the CRA considers this building worth only $300,000 on paper. You sell for $750,000.
| What the CRA Calculates | Amount | How It Is Taxed |
|---|---|---|
| Recapture: you deducted $150,000 — the CRA takes it back | $150,000 | Ordinary income — your full marginal rate |
| Capital gain on sale ($450,000 → $750,000) | $300,000 (of which $150,000 is taxable) | Capital gain — reduced rate (50% inclusion) |
Mistake 1 — Deducting a CAPEX as an operating expense. By far the most common mistake — and it can trigger a retroactive assessment.
Mistake 2 — Never claiming CCA. If you're not planning to sell in the short term, you're leaving money on the table.
Mistake 3 — Not allocating land and building values separately. Land is never depreciable. Document the allocation at time of purchase.
Mistake 4 — Mixing personal and rental expenses. If you live in your plex or use your cottage personally, prorate.
CAPEX or OPEX: the distinction is simple in theory, but grey areas exist. The key is to document every expense properly — keep all your receipts, with photos when possible — and discuss with your accountant before filing your return.
📌 Concrete action: Create a simple spreadsheet right now separating your expenses into two columns: 'OPEX — deductible now' and 'CAPEX — to depreciate'. Fifteen minutes per quarter and you'll have a clear picture of your tax situation all year long.

Q: How do I know if an expense is CAPEX or OPEX?
A: The basic rule: if the expense restores something to its original state, it's OPEX. If it improves the condition, extends useful life, or increases value, it's CAPEX. When in doubt, consult your accountant.
Q: Do I have to claim CCA every year?
A: No, it's optional. You can choose not to claim it in certain years (e.g., if you plan to sell soon). Not claiming it doesn't forfeit past deductions — the CRA uses the residual value of your class.
Q: Can I depreciate both land and building?
A: No. Land is never depreciable, because it doesn't deteriorate. Only the building enters your CCA calculation. You must allocate the purchase price between land and building.
Q: What exactly is recapture of depreciation?
A: When you sell, the CRA compares the sale price to the residual value of your class. If you sell for more (which is almost always the case), the difference is taxed as ordinary income. That's the recapture of depreciation.
