Self-employed? Here is how lenders actually read your income
Your tax return tells a different story than your gross billing. This is what lenders keep, and what they ignore.
Being self-employed changes how a lender reads your file. Your gross billing can look strong, but that is not the number on your notice of assessment. Banks compare salaried employees using a single T4; for you, they rebuild an eligible income from tax returns, financial statements, and sometimes bank deposits.
Net income, not gross revenue
A lender does not use your annual invoicing. It uses declared net income after legitimate deductions: depreciation, office costs, vehicle expenses, contributions. Two business owners with the same gross revenue can end up with very different eligible incomes depending on how their accountant structured the return.
CMHC generally requires at least two years of documented self-employment for most insured mortgages. Some banks ask for three. Without enough history, the file often moves to an alternative lender that accepts a more flexible income proof, on different terms.
The two-year average
When income swings year to year, most lenders use the average of the last two tax years, or sometimes the lower of the two if the trend is downward. One strong year on its own is rarely enough; one weak year can follow you through the whole process.
Aggressive write-offs reduce tax, but they also reduce borrowing power. Many self-employed buyers only discover that trade-off when they are already under offer.
What the lender will ask for
Expect to provide the last two notices of assessment, financial statements signed by an accountant or a complete T2125, business bank statements, and sometimes active contracts that show ongoing work. For a corporation, the lender may also want corporate financials and a letter from your accountant.
A file assembled before you walk into a lender avoids the back-and-forth that delays an accepted offer. If you are planning a purchase within the next twelve months, a conversation with your accountant about declared net income is worth having now.
When alternative lending enters the picture
If net income is too low for a traditional bank, a B lender or private lender may accept income proof based on bank deposits, recurring contracts, or a more recent average. Terms differ: higher down payment, insurance premium, shorter amortization. That is not a penalty; it is a different reading of the same file.
The rules on minimum down payment still apply, but the amount you qualify for changes with the income the lender keeps.
How I structure this kind of file
I start by estimating what each lender tier will likely retain before shopping your application. I tell you plainly whether a traditional bank is realistic with your last two returns, or whether an alternative lender is the more direct path. When a modest adjustment to declared net income could open a door without waiting for a third full year, I coordinate the timing with your accountant as well.
A first conversation costs nothing and commits you to nothing. Reach out before filling out an online application that could leave an unnecessary mark on your file.
