How Lenders Assess Self-Employed Income for a Mortgage (2026)
Lenders use your CRA-reported income averaged over two years, not gross revenue. How sole proprietors and incorporated owners are assessed, add-backs included.
For a self-employed borrower, "income" is what you reported to CRA, averaged over the last two years, with the more recent year capped at a modest increase over the prior one. Sole proprietors are assessed on line 15000 (net business income after expenses) with some add-backs: CCA, business-use-of-home, sometimes a 15% gross-up. Incorporated owners are assessed on salary and dividends drawn (T4/T5), or on the corporation's retained earnings under some lender programs. Expenses you deducted to minimize tax reduce the income you can borrow against; a $140,000 gross practice reporting $78,000 net qualifies like a $78,000 employee. Insured stated-income programs and alternative lenders exist for those with strong businesses and light tax returns, at a price.
Figures come from the CostToClose affordability calculator.
The three methods
| Method | Who | Income used | Documents |
|---|---|---|---|
| Two-year average of reported income | Sole proprietors, partners, incorporated owners taking salary/dividends | Average of the last two years' line 15000 (or T4 + T5), current year no more than ~20% above prior | Two years of T1 Generals and Notices of Assessment; proof taxes are paid; business licence or articles; often 6–12 months of business bank statements |
| Add-backs | Same, at most lenders | Reported income plus CCA, business-use-of-home, and at some lenders a 15% gross-up on net income | Financial statements or T2125 showing the deductions |
| Stated income (insured) | Self-employed 2+ years who cannot document sufficient income | Income "reasonable" for the business, declared and verified as plausible | 10% minimum down; NOAs proving no taxes owing; business documents; CMHC/Sagen/Canada Guaranty programs with a premium surcharge |

Worked example from the calculator
Electrical contractor, sole proprietor, 10% down on a $600,000 home in Alberta, 4.49% (qualified at 6.49%):
| Item | Year 1 | Year 2 |
|---|---|---|
| Gross billings | $128,000 | $140,000 |
| Net business income (line 15000) | $70,000 | $78,000 |
| CCA claimed (truck, tools) | $6,000 | $6,000 |
| Business-use-of-home | $2,400 | $2,400 |
| Qualifying income (two-year average with add-backs) | $82,400 | |
| Income needed for $600,000 at 10% down, tax $325, heat $220 | ≈ $131,400 |
Declined on the two-year average. Options: a stated-income program at an insurer (income declared at $120,000 as reasonable for the trade, 10% down, premium surcharge), a larger down payment, a co-borrower, or a lower price ($400,000 qualifies at about $89,900). Reproduce this.
What helps
- Two clean years. Late filings, taxes owing, or a big drop in year two are the common declines. Pay the balance before applying and bring the receipt.
- Consistency. Lenders read the T2125; income that swings 40% between years gets the lower figure or an average.
- Corporate structure. Some lenders will use net income from the corporation's financial statements (with a gross-up) rather than what you drew, if you own 100% and the business is established.
- Timing. If year two will be much better, waiting to file it before applying can lift the average materially.
- Alternative lenders (B lenders) use bank-statement income (6 to 12 months of deposits) at rates roughly 1% to 2% above prime lenders, with a 1% fee and 20% down. A common bridge for two or three years while the tax returns catch up.
Documents to have ready
Two years of T1 Generals with all schedules, two NOAs, proof of taxes paid, business registration or articles and a current profile, GST/HST account status, 6 to 12 months of business bank statements, and for incorporated owners two years of financial statements and the T2. A signed letter from your accountant confirming ownership and income history helps.
Frequently asked questions
How do lenders calculate income for the self-employed?
A two-year average of the income you reported to CRA (line 15000 for sole proprietors; salary and dividends for incorporated owners), with add-backs for CCA and business-use-of-home at most lenders.
Can I use my gross income if I'm self-employed?
No. Lenders use net reported income after expenses. Deductions that reduce your tax also reduce your borrowing power.
What is a stated-income mortgage?
An insured program for self-employed borrowers with at least two years in business who declare an income reasonable for their trade rather than proving it through tax returns; it requires 10% down and carries a higher premium.
How many years of self-employment do I need for a mortgage?
Two years of filed returns at most lenders; some accept one year with a prior history in the same field.
Do B lenders accept self-employed borrowers?
Yes, commonly using bank statements to establish income, with 20% down, a lender fee, and rates above those of the big banks.
