CMHC Self-Employed Income Policy Still Uses 15 Percent After Four Years
The Canada Mortgage and Housing Corporation adjusted its self-employed income treatment for mortgage qualification in June 2022. Four years later, the rule still applies the same 15 percent gross-up to reported income when calculating how much a self-employed borrower can afford to borrow.
Most lenders apply a haircut to self-employed income, they reduce the number before deciding what mortgage you qualify for, on the assumption that income reported by a business owner carries more volatility than salary. CMHC does the opposite. When you apply for mortgage insurance through CMHC as a self-employed borrower, the insurer increases your reported income by 15 percent before running the debt service calculations.
This matters because the direction of the adjustment changes who qualifies and by how much. A salaried borrower earning $80,000 qualifies based on $80,000. A self-employed borrower who reports $80,000 on their tax return qualifies based on $92,000 under CMHC's approach. That additional $12,000 in calculated income translates to roughly $50,000 more in borrowing capacity at current stress-test rates.
The gross-up accounts for tax deductions that reduce reported income without reducing actual cash flow. A contractor who writes off vehicle expenses, a portion of home office costs, and business meals against revenue shows lower net income on a T1 than someone earning the same amount as salary. CMHC's policy is designed to level that field by adding back a standardized estimate of those deductions before comparing the self-employed borrower's capacity to service debt against a salaried borrower's.
Why the number hasn't moved
The 15 percent figure has held since the policy came into effect. That stability is unusual in mortgage regulation, where stress-test rates, loan-to-value limits, and amortization maximums shift every few years in response to housing-market pressure or default-rate trends. CMHC reviewed residential lending practices twice in that window, in 2024 and again in early 2026, and left the self-employed gross-up unchanged both times.
The consistency suggests the model is working as intended. Default rates among insured self-employed borrowers have tracked close to the rates for salaried borrowers over the same period, which removes the main reason regulators adjust these factors. When a policy consistently produces acceptable outcomes, there is less pressure to revise it.
What you still need to document
The gross-up only applies once you meet CMHC's documentation threshold. That requirement is 24 consecutive months of financial statements, which usually means two full years of Notice of Assessment from the Canada Revenue Agency. If you are 18 months into self-employment and showing strong income, the gross-up does not help you yet. You wait for the two-year mark or you look for alternative lending products that accept shorter histories at higher cost.
The statements must be consecutive. A borrower who was self-employed in 2023, worked salary in 2024, then returned to self-employment in 2025 cannot combine the 2023 and 2025 years to meet the threshold. CMHC treats that case as a new self-employment start.
Business structure affects how income is counted. If you operate as a sole proprietor, CMHC uses the net income line from your T1. If you own a corporation and pay yourself salary or dividends, the calculation pulls from both personal and corporate returns and the gross-up applies to the combined amount that reaches you personally.
What changed and what did not
The update in June 2022 introduced the gross-up for the first time. Before that date, self-employed borrowers applying for CMHC insurance had their reported income treated at face value with no adjustment up or down, which put them at a disadvantage compared to conventional insured programs that applied smaller haircuts or used averaging methods that smoothed multi-year income. The introduction of the 15 percent add-back closed that gap.
The number itself, 15 percent, is the same today as it was in 2022. As of September 30, 2026, CMHC's policy page confirms the figure without revision. If you read older material citing the same percentage, the guidance remains current.
