Calculating income: self-employed and incorporated

Why self-employed income looks different on paper

A self-employed borrower's line 15000 total income and a T4 employee's salary are not comparable numbers, because a self-employed borrower's accountant is usually working to minimize taxable income legally through deductions, write-offs and timing — the opposite incentive of a T4 employee, whose employer reports gross pay with no discretion. A borrower who nets $120,000 in real cash flow may show far less on line 15000 after legitimate business deductions, which is precisely why self-employed underwriting exists as its own discipline rather than a footnote to employed income.

The standard documentation approach

The conventional path uses two years of personal Notices of Assessment and T1 Generals (with all relevant statements, such as a T2125 for a sole proprietor), looking for income that is stable or increasing. Underwriters will consider reasonable add-backs — non-cash or one-time expense items that reduced taxable income without reducing real cash flow — but this is done carefully and case by case rather than as an automatic formula, and a business with declining or highly volatile income year over year draws more scrutiny regardless of the most recent single year's number.

Insurer alternative-income programs

Both major private mortgage insurers publish programs built specifically for this borrower profile. Sagen's Business for Self (Alt. A) program is designed for self-employed borrowers with a minimum two years in business who cannot fully document income through the standard NOA route, requiring documentation appropriate to the business structure (tax filings, business licence, GST/HST summary, or audited statements for a corporation) and a stated, declared income that must be reasonable for the industry and business size, with the required credit score threshold rising if the loan-to-value exceeds 80%. Canada Guaranty's Low Doc Advantage similarly requires a minimum two years of self-employment, a signed application declaring income, and the most recent Notice of Assessment retained by the lender, with a minimum 10% down payment of which at least 5% must come from the borrower's own resources rather than being fully borrowed or gifted.

These are insurer-published categories, not a guarantee of approval on any given file, and their specific terms can change — the point for a broker to internalize is that a self-employed borrower who cannot fully document income through the standard route is not automatically stuck; there is a defined, publicly described alternative path to explore before assuming a B-lender solution is the only option.

Incorporated borrowers: whose income is it?

An incorporated borrower's personal qualifying income is generally limited to what they actually draw from the corporation as salary and dividends, evidenced by their personal T1 General and NOA — not the corporation's total profit. Retained earnings sitting inside the company are the company's, not the shareholder's, until drawn out, though some lenders will consider a corporation's financial strength as supporting context for the file even when they cannot count retained earnings directly as personal income. Corporate documentation typically includes two years of corporate financial statements, T2 returns with Schedule 100 (balance sheet) and Schedule 125 (income statement), the corporate NOA confirming no tax arrears, and confirmation of the borrower's ownership percentage.

Common pitfalls

Two mistakes recur constantly. The first is a business owner who, on their accountant's advice, minimizes personal income for years and then discovers that same minimization makes qualifying for a mortgage far harder than expected — a conversation worth having with self-employed clients well before they need to apply, not after. The second is restructuring compensation (suddenly paying a large dividend, or changing salary) in the months immediately before applying, which usually reads as engineered rather than organic and invites more scrutiny, not less.
