Rental & real estate

Rental property tax turns on a handful of decisions.

One property or a dozen. Rental income looks simple on the form and is anything but underneath it. Most of the tax outcome comes down to three or four questions, and owners routinely get them wrong in ways that cost real money years later.

The basics, quickly

Rental income and expenses go on the T776, Statement of Real Estate Rentals, filed with your personal return. One form covers all your properties, with the income and expenses broken out per property. If you own with someone else, the split follows ownership, not whoever happens to collect the rent.

Ordinary deductible costs are what you would expect: mortgage interest but not principal, property tax, insurance, utilities you pay, condo fees, advertising, management fees, and professional fees. Where it gets interesting is everything else.

Repairs or improvements, which is the question that never goes away

A current expense is deducted in full this year. A capital expenditure is added to the cost of the property and only comes back to you when you sell. Same cheque, radically different tax outcome, and the line between them is judgment rather than a rule.

What the analysis turns on:

This is worth a conversation before the work, not after. Once the invoice says "renovation" your options narrow.

Should you claim CCA?

You may claim capital cost allowance on a rental building. Whether you should is a genuine decision rather than a default, and it turns on your own rates rather than on a rule of thumb.

It cannot create or increase a rental loss. CCA on rental property is restricted, so it can bring rental income down to nil but no further. If you are already at a loss it does nothing.

It is a deferral rather than a saving. CCA claimed on the building is recovered when you sell, as recapture, taxed as ordinary income in the year of sale. What it does not do is change your capital gain. CCA reduces undepreciated capital cost, not adjusted cost base, so the gain above your original cost is the same whether you claimed CCA or not. The trade is simply a deduction now against matching income later.

Which makes it a question about rates and timing:

Worth deciding deliberately rather than because the software offered.

When a property changes use

Moving into a rental, or moving out of your home and renting it, is a deemed disposition for tax purposes. You are treated as having sold the property at fair market value and immediately reacquired it, even though no money moved and nothing changed on title.

That can trigger a taxable gain in a year you received no cash to pay it with. There are elections available that change the outcome, and they have deadlines and consequences of their own, including how they interact with the principal residence exemption.

The practical version: tell your accountant before you move, not at tax time. Elections have to be filed with the return for the year of the change, and options that were available in March are gone by the following January.

The same applies to converting part of a home, such as taking in a tenant or building a basement apartment. A partial change of use has its own treatment, and doing it carelessly can put part of your home's principal residence exemption at risk.

Selling

Three things decide the tax on a sale.

A principal residence sale must be reported even when the gain is fully exempt. See personal tax.

The situations that need their own conversation

What I do with it

The T776 and the personal return, obviously. More usefully: getting the cost base tracked properly per property so that ten years of capital spending is documented when you eventually sell, deciding the CCA question deliberately, catching a change of use before it happens rather than after, and telling you which of the repairs you are planning this year are deductible this year.

If the portfolio is large enough to need it, proper per property reporting so you can see which ones are earning their keep. See customized accounting solutions.

Commercial: rent rolls and CAM

Commercial property runs on two documents that residential landlords never meet, and both are places where money quietly goes missing.

The rent roll

A rent roll is the schedule of every unit and what it produces: tenant, area, lease start and end, base rent, escalation dates, additional rent, deposits held, options to renew and any free-rent or fixturing periods.

It is the operating document for the property and it is what a lender or a buyer asks for first. Three things make one reliable:

Common area maintenance

Under a net lease the tenant pays base rent plus a share of operating costs. CAM is the mechanism, and the arithmetic is simple while the discipline is not.

Costs are pooled, then allocated to each tenant by their proportionate share, usually rentable area over total rentable area. Tenants pay monthly estimates through the year, and after the year end the actual costs are calculated and the difference is billed or credited. That reconciliation is the part that gets deferred and then skipped.

Where it goes wrong:

Tenants with any sophistication have audit rights and use them. A reconciliation that cannot be supported line by line is a bad position to defend, and the practical answer is to run it annually, on time, from records that separate recoverable from non-recoverable as costs are incurred rather than at year end.

Questions

Should I claim CCA on my rental property?

It depends on your rates, and it is worth deciding rather than defaulting. CCA cannot create or increase a rental loss, and whatever you claim on the building comes back as recapture when you sell, taxed as ordinary income. It does not change your capital gain, because CCA reduces undepreciated capital cost rather than adjusted cost base. So it is a deferral: a deduction now against income later. That is often worth having if your marginal rate is similar in both years, and less attractive if you would deduct cheaply now and recapture expensively later, or if the recapture would spike your income in the year of sale.

Is a new roof deductible?

It depends on what was done and why, and the whole roof rule of thumb is less reliable than people think. Replacing a roof in equivalent materials, putting the building back to the condition it was in after damage or wear, can be a current expense even where the entire roof was done. Upgrading to better materials points to capital, because you improved the property rather than restored it. So does work carried out to make a property you have just bought usable, since you acquired it in that state.

Can I deduct my mortgage payment?

The interest portion, yes. The principal, no, because that is repaying borrowed money rather than an expense. This is one of the most common misunderstandings and it can be a large number either way.

I am moving into my rental. Does that matter?

Yes, quite a lot. A change of use is a deemed disposition at fair market value, which can create a taxable gain in a year with no cash from a sale. There are elections that change the result, they have to be filed on time, and they interact with the principal residence exemption. Raise it before you move.

I own the property with my spouse. How do we split it?

According to actual ownership and the source of the funds used to acquire it, not according to whichever return produces the better result. If ownership and the intended split do not match, that is worth sorting out properly rather than at filing time.

Do I need to charge HST on rent?

Long term residential rent is generally exempt. Short term accommodation and commercial rent are different, and thresholds and registration come into play. If you are running anything other than a straightforward residential tenancy, ask.

What records should I be keeping?

Everything that touches the cost base, forever, not just the six years for ordinary records. Capital improvements you cannot deduct now are what reduce your gain on sale, and the receipt from 2014 is the one you will want in 2034.

This page describes rental and real estate tax in general terms as at August 2026 and is not advice for your situation. The rules around change of use, flipping, short term rentals and HST rebates carry deadlines and change from time to time, so check your own circumstances.

Ask before, not after.
