The write-offs that save you tax can cost you the mortgage. Plan your self-employed mortgage first.
Lenders don't look at what your business earns. They look at what your tax return declares, averaged over two years. See the real tradeoff, then build the two-year plan that gets you approved.
Step 1 · The number lenders actually use
Your two-year average
Most lenders start with line 15000, total income, on your last two Notices of Assessment and average the two. For a sole proprietor that figure is your business income after expenses plus anything else you reported that year, so it is not purely business profit. That gap is usually why the number on your NOA and the number in your head do not match. Your best single year isn't the number, the average is.
Your estimated qualifying income
$0
The two-year average, plus any add-backs some lenders allow for non-cash expenses like depreciation or business-use-of-home.
Step 2 · The tradeoff nobody shows you
Every write-off has two prices
Writing off more lowers your tax bill, but it also lowers the income a lender sees, and because they average two years, the hit lingers. Drag the slider to watch both sides move.

Step 3 · Your two routes to yes
There's more than one way to qualify
If your tax return doesn't tell the whole story, your bank statements often can. Tap each path.
Path 1
The A-lender route
The mainstream route, qualifies on your filed income.
- Uses your two-year average net income from your tax returns and NOAs.
- The widest choice of terms, and the goal for most buyers.
- Typically wants a credit score around 680 or higher.
- Rewards stable or growing income and fully paid CRA balances.
- Best if your declared income comfortably supports the purchase.
Path 2
The bank-statement route
Qualifies on real cash flow, not just line 15000.
- Alternative and stated-income lenders review 6 to 12 months of business deposits.
- They total deposits, subtract an industry expense factor, and use the rest as income.
- Rates run a little higher, but it reflects how you actually earn.
- These are fully underwritten Canadian lenders, not the no-doc loans from 2008.
- Best if you write off heavily, recently pivoted, or have strong cash flow but low taxable income.

Where does your file stand today?
Tap everything that's true. The more boxes you tick, the smoother and cheaper your approval. The gaps are exactly what we'd work on together.

How this tool works
The method behind the self-employed estimate
This tool gives business owners a rough sense of how a lender might view their income. Business-for-self files turn almost entirely on documentation, so treat the output as a starting point for a conversation rather than a number to plan around.
The tax lines, and what they actually mean
- Line 15000 is total income. It is not net income and it is not business income. It can include employment income, investment income, rental income and other sources alongside the business.
- Line 23600 is net income, which is total income after specific deductions. It is a different figure again.
- Neither is automatically your qualifying income. Lenders build a qualifying figure from your documents and their own program rules. Two lenders can reach different numbers from the same tax return.
How lenders generally look at it
Most prime lenders average the last two years of declared income and work from that. Some programs recognise adjustments, or accept alternative documentation, or look at business financial statements rather than personal returns. Which route applies depends on how your business is structured and what you can evidence.
qualifying income ≈ average of the last two years of declared income
Then tested against debt service ratios at the qualifying rate,
including property taxes, heat, condo fees and other debts
Sole proprietor and incorporated are different problems
A sole proprietor is usually assessed on personal tax returns and notices of assessment. An incorporated owner has a further question: how much of the corporation’s income can be counted, which depends on ownership, access to the funds and what the financial statements show. Retained earnings are not a business-expense add-back, and whether corporate income can be used at all is program-specific.
What this tool cannot tell you
- Which add-backs a lender will accept. Vehicle depreciation, home office and similar deductions are not universally added back. Some lenders allow some of them, some allow none.
- Whether you meet the business history requirement. CMHC describes around two years of business operation or related experience as recommended, with flexibility in some cases. It is not an absolute rule across every lender.
- What documents you will need. That depends on the lender and the program, and it is the single biggest cause of delay on self-employed files.
- Anything about your tax position. Nothing here is tax advice. Talk to your accountant before changing how you draw income in order to qualify.
