Quick answer: Because you own the company that pays you. Your salary is on a T4, but you decide what it is, so most lenders treat you as self-employed. That means they use your filed personal tax returns, usually the last two years, and if your income went down they use the lower, more recent year. Cutting your salary to leave money in the company can cost you. In our example, an Ottawa owner who dropped from $110,000 to $90,000 qualifies for about $96,000 less than one who kept it steady.
In Ottawa this often comes up with consultants who left a salaried job, sometimes in the public service, and now bill through their own corporation. The pay can look the same as before. The lender reads it differently.
Why does a lender call you self-employed?
A T4 from your own corporation is employment income for tax. For a mortgage, the question is who sets that salary. When a regular employer pays you, the lender can rely on an employment letter and a pay stub. When you own the company, you could raise your pay the month before you apply, so the lender looks past the T4 to your tax history and the business behind it.
In our placement experience, lenders usually ask an incorporated owner for:
- two years of personal tax returns (the full T1 General) and Notices of Assessment
- your T4 slips, and T5 slips if you also take dividends
- a corporate search showing you own the company and how long you’ve owned it
- often, the company’s financial statements
Which tax years count?
The two most recent years you’ve filed and had assessed. For an approval in late 2026, that’s usually 2024 and 2025. Your 2026 income won’t count until that return is filed and assessed. If you or your spouse are self-employed, the filing deadline is June 15, but any balance owing was due April 30 (CRA).
Two things follow from that. If your strongest year is this one, a lender can’t use it yet. Some lenders will look at this year’s pay for a regular employee, but not for an owner. And if a Notice of Assessment shows tax owing, expect the lender to want proof it’s paid before your mortgage funds.
What happens if you lowered your salary?
The lender averages your two years only if your income is rising or roughly flat. If it fell, most lenders use the lower, more recent year. That’s where owners get caught: a lower salary can be a sensible tax decision, and it still reads as falling income.
Here’s an Ottawa owner with $500 a month in property tax and heat and no other debts. At the best insured 5-year fixed we tracked as of October 27, 2026 (4.64%), the qualifying rate is 6.64% (OSFI). Housing costs can’t be more than 39% of income on an insured mortgage (CMHC). Over 25 years:
| Salary from the company | Income the lender uses | Largest mortgage |
|---|---|---|
| Steady: $110,000 in 2024 and 2025 | $110,000 | about $453,000 |
| Rising: $90,000 in 2024, $110,000 in 2025 | $100,000 (two-year average) | about $405,000 |
| Cut: $110,000 in 2024, $90,000 in 2025 | $90,000 (the lower, recent year) | about $357,000 |
The last two rows have the same total salary over two years. The owner who cut their pay qualifies for about $48,000 less than the one whose pay went up, because the lender reads a falling trend. Some lenders will still average a small dip. A $20,000 drop isn’t small.
The money left in the company doesn’t disappear. Some lenders will consider dividends you’ve taken, averaged over two years, and a few will look at profit kept in the company. Many prime lenders won’t count retained profit at all, so it’s not something to plan on without asking.
How long do you need to have owned the company?
CMHC recommends at least 24 months operating the business or experience in the same line of work, and its program covers incorporated owners as well as sole proprietors (CMHC). If you worked as a sole proprietor before incorporating, that time usually counts toward the two years. If you incorporated less than two years ago after years doing the same work as an employee, a few lenders will look at the file, usually once your first year as an owner is filed.
When doesn’t this apply?
If you own only a small share of the company and don’t control your pay, many lenders will treat you as an employee. Each sets its own cut-off. If your income is steady or rising and your taxes are paid, being self-employed mostly means more paperwork, not a worse rate. And if you’ve just left a salaried job and haven’t incorporated yet, see getting a mortgage after starting a new job in Ottawa. Owners coming up to renewal should also read what can go wrong at renewal for the self-employed.

Frequently asked questions
I get a T4 from my own corporation. Am I self-employed for a mortgage?
Usually, yes. For tax you’re an employee of your corporation, but lenders look at who controls the company paying you. If that’s you, most treat you as self-employed and ask for your personal tax returns and Notices of Assessment.
Which years of income will a lender use?
Usually the two most recent tax years you’ve filed and had assessed. For an approval in late 2026, that’s 2024 and 2025. This year’s income generally can’t be used for an owner until it’s filed.
What if I lowered my salary to leave money in the company?
Then most lenders use the lower, more recent year instead of averaging. In our example, cutting a $110,000 salary to $90,000 lowers what an Ottawa owner can borrow from about $453,000 to about $357,000.
Can money left in my corporation help me qualify?
With some lenders. Dividends you’ve taken can often be averaged over two years. A few lenders will consider profit kept in the company, but many prime lenders exclude it, so ask before you count on it.
Do I need to pay my taxes owing before I get a mortgage?
Expect so. If your Notice of Assessment shows a balance owing, lenders usually want proof it’s paid before the mortgage funds. Taxes are due April 30, even though self-employed people have until June 15 to file.
