Why your qualifying income looks different from what you earn
If you run a business, you have two incomes. There's the money the business actually generates and supports your life with, and there's the number that lands on your tax return after your accountant has done a good job. A good accountant's entire mandate is to make that second number smaller. Mortgage lenders read the second number.
That's the whole puzzle in one sentence, and everything else on this page is about closing the gap between the two. There are established, lender-sanctioned ways to do it. My job is knowing which lender applies which method, and building the file so the underwriter sees the business the way you do.
The standard starting point: a two-year average of line 15000
Most lenders begin with line 15000 of your T1 General — total income — and average the two most recent years. Two years smooths a strong year against a quieter one, and it's the baseline the mortgage insurers work from too. Sagen's Business for Self program, for example, verifies income using line 15000 from the borrower's most recent years' Notice of Assessment.
Two useful details. First, when the most recent year is higher than the prior year, many lenders will still use the two-year average, so a strong recent year takes time to fully count — worth knowing if you're planning a purchase around a growth year. Second, if your most recent year is the lower of the two, some lenders will simply use that year. Knowing in advance which approach a given lender takes is often the difference between a comfortable file and a tight one.
Add-backs: putting real income back on the page
Not every deduction on your return represents money that actually left your pocket. Underwriters know this, and the insurers explicitly recognise it — CMHC's self-employed program allows self-employment income to be increased by 15%, or to be adjusted through an add-back approach of eligible deductions.
The items underwriters most commonly look at:
- Capital cost allowance. Depreciation is an accounting entry, not a cash outflow. It's the most routinely accepted add-back there is.
- Business-use-of-home. If you're claiming a portion of a home you already live in, the underwriter is often already counting that housing cost elsewhere in the ratios.
- One-time and non-recurring expenses. A single large equipment purchase or a one-off legal bill isn't your ongoing cost structure. This needs to be documented, not just asserted.
- The employer portion of CPP on self-employment earnings. Depending on lender policy, some or all of it comes back.
Add-backs are a documentation exercise, not a negotiation. A short letter from your accountant identifying each item and confirming it's non-cash or non-recurring turns a claim into evidence. When I take on a business-for-self file, requesting that letter early is one of the first things I do — it's usually the single highest-value document in the package.
Sole proprietor, incorporated, or commissioned
These three get treated quite differently, and knowing which one you are shapes the whole file.
Sole proprietors and partnerships report on the T1 General with a T2125 Statement of Business or Professional Activities. Your business income and personal income are the same pool, so line 15000 plus add-backs is a fairly direct read. It's the most straightforward of the three.
Incorporated business owners have a company that files its own T2 return. You might pay yourself salary, dividends, or a mix. Salary shows on a T4 and is read almost like employment income, which many owners find is the cleanest path. Dividends appear on your T1 and lenders generally use the actual amount received. Where it gets interesting is retained earnings — profit that stayed in the corporation. Several lenders will consider retained earnings as available income where you own a controlling interest and the corporation's financial statements show the business can sustain the distribution, usually supported by an accountant's letter. Not every lender does this, and among those that do the treatment varies, so it's a lender-selection question more than a paperwork question.
Commissioned earners sit somewhere in between. If you're a T4 employee earning commission, most lenders average the commission portion over two years while accepting base salary at face value. If you receive a T4A or invoice as a contractor, you're treated as business-for-self, and the two-year average applies to the whole amount.
What I'll ask you for
Gathering these in one go, at the start, is the single biggest thing that makes a self-employed file move quickly.
| Document | Sole proprietor / partnership | Incorporated |
|---|---|---|
| T1 General, complete, 2 years (with T2125) | Yes | Yes |
| Notices of Assessment, 2 years | Yes | Yes |
| Proof no taxes are outstanding | Yes | Yes |
| T2 corporate tax returns, 2 years | — | Yes |
| Accountant-prepared financial statements, 2 years | If available | Yes |
| Articles of incorporation | — | Yes |
| Business licence or GST/HST registration | Yes | Yes |
| T4s / T5s from the corporation | — | If you pay yourself |
| Business bank statements, 6–12 months | Often | Often |
| Personal bank statements for the down payment, 90 days | Yes | Yes |
| Accountant's letter (add-backs, ownership %, retained earnings) | Recommended | Recommended |
On the down payment paper trail
Every lender wants 90 days of history on your down payment, and business owners are the group most likely to move money between personal and corporate accounts. If your down payment is coming out of the corporation, or arriving as a lump-sum draw, tell me at the start and keep the statements for both sides. Any single deposit of $3,000 or more will be looked at, and a clean explanation supplied up front is worth far more than one supplied under deadline. This is standard anti-money-laundering practice and it applies to every file, not just yours.
Stated income and alternative documentation programs
Where the two-year average doesn't reflect the business, there are programs built specifically for this — and they're mainstream, insured products, not a workaround.
The insurers offer business-for-self programs where you declare an income that's reasonable for your industry, your time in business and your business type, supported by evidence of the business's actual activity rather than the tax return alone. Sagen's Business for Self (Alt. A) program allows up to 90% loan-to-value on a purchase, with property values up to $1,500,000 where the loan-to-value is above 80%. Premiums on these programs run higher than standard insured premiums. That's the trade for stating income, and it's a trade many business owners are glad to make.
The evidence that supports a stated income is usually some combination of business bank statements showing consistent deposits, GST/HST filings that corroborate revenue, invoices or contracts, and an accountant's confirmation of gross revenue. Think of it as proving the business rather than proving the tax return.
A lenders and B lenders for business-for-self files
Both have a proper place, and I use both regularly.
A lenders — the banks, credit unions and monoline lenders — offer their sharpest pricing and are the right home for a business owner with two clean years, tidy financials and reasonable add-backs. Plenty of self-employed clients belong here and don't realize it. Credit unions deserve a specific mention: they're provincially regulated, they're often more comfortable with an owner-operator's financials than a national bank's centralized underwriting is, and in the Okanagan they're a genuinely strong option.
B lenders are built for flexibility. They'll look at a shorter time in business, a more complex corporate structure, or income that's better evidenced by deposits than by line 15000. The usual approach is a shorter term — often a year or two — while the business builds the tax history that opens the A-lender door. I've had many clients start on a B-lender term and move to an A lender at renewal with a stronger file. Planning that exit at the outset is part of the job.
How long you need to have been self-employed
Two years is the standard, and it's what most lender and insurer guidelines are written around — Sagen requires a minimum of two years business-for-self tenure confirmed by third-party documentation.
But two years isn't an absolute wall, and this is where a broker's knowledge of individual lender appetite matters most. CMHC's self-employed guidance recommends 24 months while expressly allowing for borrowers with less, where there are supporting factors: acquiring an established business, sufficient cash reserves, predictable earnings, relevant training or education, or a demonstrated history of managing credit.
The pattern I see most often is someone who spent years as an employee in the same field and then went out on their own. That continuity of experience carries real weight with an underwriter, and it's exactly the kind of context that has to be written into the submission rather than left for someone to infer from the documents. If you're in year one or year two, it's absolutely worth a conversation — there is more room here than most people expect.
How I approach these files
Self-employed applications aren't harder, they're just more detailed. The work is in reading the returns properly, identifying every legitimate add-back, getting the accountant's letter right, and then placing the file with a lender whose written policy actually fits the structure of your business. With 50+ lenders on the panel — banks, credit unions, monolines and alternative lenders — that placement decision is the leverage. On a conventional mortgage, there's no cost to you to have me do it.
