Updated Checked by the Tax-Services.ca editorial team How we check
A real estate tax accountant is worth hiring on the year you sell a property that isn’t your main home, or the year you start renting one out. Before then, most owners can manage with a good spreadsheet and the CRA’s rental guide. We couldn’t verify anyone’s fees, so this page tells you how to choose and what to check instead of naming a price.
When does a real estate tax accountant pay for themselves?
Pick the moment, not the firm. A sale creates a one-off tax bill that can be large. Take an Ontario seller with $90,000 of other income who sells a rental with a $300,000 gain. The capital gains tax calculator puts the extra tax at about $65,670, using the general 50% inclusion rate (we couldn’t find the 2026 rate on a CRA page, so check it).
That’s the kind of number where an hour of someone’s time to check the cost base and the timing is easy to justify. A $1,000 mistake on the adjusted cost base moves the tax by hundreds, so the money is in the details.
If you’ve only got one rental and the books are clean, you probably can skip the expert and file yourself.
What should a real estate tax accountant be able to do?
| Situation | What the CRA pages say | Question to ask |
|---|---|---|
| Renting out a unit | Report gross rents, expenses and CCA on Form T776 | Will you claim CCA, and what happens when I sell? |
| Selling a second property | Gain is reported on Schedule 3 | How do you work out my adjusted cost base? |
| Selling your main home | May be exempt, but the sale is still reported, with Form T1255 | Do I qualify for the exemption in every year I owned it? |
| Owner has died | Property treated as sold at fair market value | Is there a spouse rollover, and when is the final return due? |
If they can’t answer those four without looking it up, they aren’t your person. For a rough idea of the rental side yourself, try the rental income tax calculator.
What does the rental side look like in dollars?
A basement rented at $2,500 a month brings in $30,000 over a year. With $14,000 of expenses, the profit you report is $16,000, as in the example above. The expenses are where an accountant checks your paperwork: which repairs are current costs, which are upgrades, and whether claiming depreciation now will cost you later. That choice can matter more than the rent itself, and it’s a ballpark decision you want to make with someone who sees the whole picture.
How do you choose one?
We won’t name a firm, because we can’t check one. A few questions are more useful than any ranking.
How many rental or sale files did they handle last year? Will they see the deal before it closes, or only after? Who signs the return, and who answers your emails? Ask for the fee as a fixed quote for the specific job, in writing.
And be wary of anyone who promises to “eliminate” tax on a sale. Tax on the gain is the rule. What can change is timing, deductions and exemptions you truly qualify for.
What to bring to the first meeting
Bring the purchase and sale statements from the lawyer, receipts for major repairs or upgrades, the last two years of returns, and the T776 if you’ve been filing one. For a property you inherited, bring a valuation as of the date of death.
The better your paper, the less time you pay for. The CRA says to keep records for six years from the end of the related tax year, though proof of what you paid for a property may go back further than that.
Test your own deal first. The home sale proceeds calculator shows what is left after the mortgage, commission and tax. The rental property calculator does the same for cash flow while you hold.
Do you need one for a principal residence sale?
Usually a quick check is enough. Selling your main home may be exempt, but the sale still gets reported, as the table says, and that’s where a small slip can cause trouble later. If you rented part of it, or lived there only part of the time you owned it, that’s the time to ask for a second opinion.
Mistakes owners make when hiring
The biggest one is calling too late. Advice before you sign a sale agreement can still change things, but advice after closing can only describe them.
Another is paying for a tax return when what you needed was a second opinion on one decision. Ask for that by name, with a fixed scope and price.
The last is asking a real estate agent or a mortgage broker for tax advice. They know the market, not your return.
Where the numbers come from
Form, record and sale reporting rules are from the Canada Revenue Agency‘s rental income and capital gains guidance, read in September 2026. The $65,670 figure comes from our own calculator using 2026 federal and Ontario rates and the assumptions above. We didn’t use any fee data.
Frequently asked questions
When should I hire a real estate tax accountant?
Before you sell a non-principal property, when you start renting one out, or when you inherit property. Advice is most useful before the deal closes.
How much does a real estate tax accountant cost?
We couldn't verify fee levels. Ask for a fixed quote, in writing, for the specific job.
Do I need an accountant to file rental income?
No. The CRA provides Form T776 and a rental guide. An accountant helps most with CCA, sales and inherited property.
Do I have to report the sale of my main home?
Yes. It may be exempt, but the CRA still requires you to report it on Schedule 3 with Form T1255.
What records should I bring?
Purchase and sale statements, receipts for major improvements, recent returns and any T776 forms.
