One tax return, five different answers
Every method here starts from $64,500 — the average of your two years. What separates the answers is how much of the rest of your business a lender is willing to count: the add-backs, the gross-up, what the company kept.
Had your recent year been the lower one, every method would switch to it — including the gross-up, which is where these comparisons usually go wrong.
The income your documents support — $162,700 — is more than 30% of your $240,000 of revenue, so a stated-income lender would cut it by $90,700. If your margins really are that high, that is a conversation to have with a broker in advance rather than discovering it in underwriting.
The $85,000 retained in the company is the single largest lever on this file, and it is also the one most dependent on paperwork. No accountant's letter, no retained earnings — and the method that counts them closes.
The spread across the methods open to you is not a rate you can shop for — it is which lender reads your file, decided before you fill in a single form, and it is worth more than any rate difference you are likely to negotiate.
Knowing which lender reads a self-employed file which way is most of what a broker does. None of it is published, and your own bank runs exactly one of the five.
Talk to a brokerThe same returns, read five ways
Your bank runs the first of these and stops. Every one below it reads the same tax returns and reaches further, and none of them is something you can ask a branch for.
The average of $68,000 and $61,000. What most banks do, and where most people stop.
Adds back the $13,200 a year of CCA, business-use-of-home and one-time costs that reduced your taxable income without leaving your account. Needs an accountant's letter.
Some lenders add 15% to self-employed net income on the reasoning that it understates what you really earn. Applied to $64,500.
Counts the $85,000 your company kept last year on top of the add-backs. Needs an accountant's letter confirming it could have been withdrawn without harming the business.
Cut to $72,000 — 30% of your $240,000 revenue. Stating $162,700 would not survive the reasonability test. Priced at 6.69%.
5 of the five are open to you, spanning $402,069 of purchase price. Closed methods are never ranked — a number you cannot reach is not your best outcome.

What this does not cover
Your credit, each lender’s own overlays on the industry you work in, how seasonal or contract income is treated, and the tax consequences of paying yourself differently in order to qualify. That last one is an accountant’s question and it is worth asking a year before you buy rather than a month — the returns a lender reads in 2027 are the ones you file this spring.
A planning estimate, not an approval. Every method here varies by lender and by underwriter appetite, and add-back, gross-up and retained-earnings treatment in particular is negotiated file by file rather than published. Add-back, gross-up and retained-earnings treatment varies by lender and by underwriter and is negotiated file by file rather than published — every method here represents what a category of lender might do, not an offer. The declining-income rule is applied to every method built on your tax returns. Retained earnings are treated as last year’s retention rather than an accumulated balance, and counted only for an incorporated business with an accountant’s letter. The stated-income ceiling uses a single directional margin where real programs set one by industry. Every price is solved at the stress-tested rate against the standard GDS and TDS limits. Nothing here accounts for credit, and an outstanding CRA balance will stop an application whatever the income.

What this calculator does
If you work for yourself, your mortgage application turns on a single judgement nobody explains to you: how much of what your business actually earns a lender is willing to call income. Your bank reads line 15000 on two Notices of Assessment, averages them, and stops. That is one legitimate method. It is also the most conservative of five.
This page runs your numbers through all five, side by side, and then does the part that matters — it tells you which of them your file can actually use. A method you do not qualify for is not an option, and reporting one as your best outcome is how these tools mislead people.
On the figures this page opens with, the bank method reaches $350,820. The best method genuinely open to the same borrower reaches $752,889. Same person, same tax returns, same day — $402,069 of difference, decided entirely by which lender reads the file.
- Five methods lenders really use, with the income each one produces
- The maximum purchase price each supports, solved at the stress-tested rate
- Which methods are open to you, and plainly why the others are not
- The spread across the methods you can actually use
- A document checklist that changes with your file rather than listing everything
The rule that decides everything: declining income
If your most recent year is lower than the year before, most lenders stop averaging and qualify you on the lower recent figure instead. The logic is straightforward — they will not lend against income that has already gone away.
It is the single most consequential rule in self-employed underwriting, and it applies to every method built on your tax returns. That includes the gross-up, which is where calculators get this wrong: grossing up the two-year average lets the rule be sidestepped entirely.
The difference is not small. On a file that fell from $80,000 to $50,000, the standard method reaches $283,987. Grossing up the average instead produces $398,063 — $114,076 more purchasing power on a business whose income is shrinking. Applied properly, to the lower recent year, the gross-up reaches $318,556. No lender would honour the first figure, and no borrower should plan around it.
- A lower recent year replaces the average at most lenders
- The rule reaches every method here, the gross-up included
- On a file falling $80,000 to $50,000: $283,987 the standard way
- Grossing up the average instead would claim $398,063
- Done properly the gross-up reaches $318,556
Add-backs, and why they are counted in full
Capital cost allowance and business-use-of-home are real tax deductions that never actually left your bank account. Many lenders will add them back to your income with an accountant's letter, on the reasoning that your tax return understates what you had available to spend.
The convention is to add them to each year and then average, which returns the annual figure. On these numbers that is $13,200 a year, taking the qualifying income from $64,500 to $77,700 and the price from $350,820 to $411,660.
Halving them, as some tools quietly do, costs $30,420 of purchase price for no stated reason. A lender either accepts an add-back or it does not — there is no convention under which it counts half. What is genuinely conditional is the accountant's letter: without one, the add-back methods close and you are back to the bank's answer.
- CCA and business-use-of-home reduce tax without reducing cash
- Counted in full at $13,200 a year here, not halved
- Which lifts qualifying income from $64,500 to $77,700
- Worth $30,420 of purchase price against a halved treatment
- Entirely dependent on an accountant's letter — no letter, no add-back
What your company kept is income too, if you are incorporated
An incorporated owner usually pays themselves far less than the business earned, leaving the rest inside the company. That retained profit is money you chose not to take, and some lenders will count it as income with an accountant's letter confirming it could have come out without harming the business.
On these figures $85,000 was retained last year. Counting it alongside the add-backs is what takes this file to $752,889 — more than twice the bank's $350,820, from exactly the same tax returns.
Two things matter here. It is last year's retention, not the accumulated balance on your balance sheet: a figure built up over a decade is not one year of income, and no lender treats it as such. And it only exists inside a corporation — a sole proprietor or partner already reports business income on their personal return, so there is nothing held back to add.
- Retained profit is money you could have paid yourself and did not
- $85,000 retained here takes the file to $752,889
- Against $350,820 on the bank's reading of the same returns
- Last year's retention, never the accumulated balance sheet figure
- Incorporated files only — there is nothing to retain otherwise
Stated income is a test, not a number you pick
Alternative lenders will work from an income you state rather than one your tax returns prove — but they check it. The claim is tested against your gross business revenue at a margin typical for your industry, and cut to that ceiling if it does not hold up.
On these figures the ceiling is $72,000, being 30% of $240,000 of revenue. What the documents actually support is $162,700. So a stated-income lender would cut the claim by $90,700 — which is the useful finding here: this file is far better off documented than stated, and the alternative route is the wrong first call.
It runs the other way too. A borrower whose documents support $44,850 against $400,000 of revenue does not get handed $120,000 of income they never earned just because the ceiling allows it. A calculator that sets income to a share of revenue rather than testing a claim against it will do exactly that, and flatter a file into an application that fails.
- The ceiling here is $72,000 — 30% of $240,000 of revenue
- Your documents support $162,700, so the claim is cut by $90,700
- Which says this file should be documented, not stated
- A stated route is also priced above A-lender rates, not at them
- And a modest file is never handed income the ceiling merely permits
Two years in business is a wall, not a preference
Nearly every A-lender wants two full years of self-employment history. Below that the bank methods are closed regardless of how strong the income looks — no amount of documentation, add-backs or retained earnings moves it.
This page stops offering methods you cannot use. At one year in business, four of the five close and the spread collapses to nothing, because there is only one route left. A tool that ranked all five and reported the retained-earnings figure of $752,889 as your best outcome would be describing a mortgage no lender in the country would write for you.
That is not a reason to wait if you need to buy now. It is a reason to plan for an insured self-employed program or an alternative lender, price the premium in, and treat the A-lender route as a refinance conversation at renewal once the history exists.
- Two full years is the near-universal A-lender minimum
- Below it, four of the five methods close outright
- Income strength does not substitute for time in business
- The realistic route is an insured program or an alternative lender
- And an A-lender refinance becomes available once the history is there
What the spread is actually telling you
The gap between the best and worst method open to you is the most useful number on this page. Here it is $402,069 of purchase price, on identical income, identical returns and identical debts.
A wide spread means lender selection dominates your outcome, and applying at your own bank first — where you will get the most conservative of the five — is an expensive default. A narrow spread means your file is straightforward enough that you should be shopping rate instead, because appetite barely differs.
Either way it is not a rate you can negotiate. It is which underwriter reads the file, and that is decided before you fill in a single form.
- The spread here is $402,069 of purchase price
- Nothing about the borrower changes across that range
- A wide spread means lender choice matters more than rate
- A narrow one means your file is strong and you should shop rate
- Your own bank will almost always give you the conservative end
Using your results well
Start with your actual Notices of Assessment rather than what you think you earned, then compare the bank method against the add-back method to see what your documentation is worth in purchasing power. That difference is the concrete argument for getting an accountant's letter before you apply rather than after an underwriter asks.
Gather the checklist while you are not under time pressure. A self-employed file that arrives complete is underwritten on its merits; one that arrives in pieces over three weeks gets read as disorganised, and that reading affects decisions in ways nobody writes down.
And clear anything owing to the CRA first. An outstanding balance stops a self-employed application at almost every lender no matter which income method applies, and finding that out during underwriting costs you the deal rather than a week.
- Use your real NOAs, not your recollection
- Get the accountant's letter before you apply, not after
- Assemble the whole document package before anyone asks for it
- Clear any CRA balance or document the payment arrangement
- If your income fell, write the explanation in advance
Common questions
How do lenders calculate self-employed income in Canada?
Most commonly by averaging line 15000 across your two most recent Notices of Assessment — and if your most recent year is lower, by using that lower year instead of the average. Beyond that standard treatment, some lenders add back non-cash deductions like capital cost allowance, some gross up net income by around 15%, some count profit your corporation retained, and alternative lenders test a stated income against your gross revenue. On the default figures here those five routes span $350,820 to $752,889 of purchase price.
What happens if my self-employed income went down?
Most lenders drop the two-year average and qualify you on the lower, more recent figure. On a file that fell from $80,000 to $50,000 that means qualifying on $50,000, which supports $283,987 rather than the $398,063 an average-based gross-up would suggest. The rule applies to every method built on your tax returns, including the gross-up. Have a written explanation for the decline ready before an underwriter asks — a lost client or a documented slow year reads very differently from an unexplained drop.
Can I add back CCA and business-use-of-home to my income?
Many lenders will, because both reduce your taxable income without any money leaving your account. They are counted in full for a typical year and added before averaging — $13,200 a year on these figures, which lifts qualifying income from $64,500 to $77,700 and the price by $30,420. All of it depends on an accountant's letter confirming the figures; without one the add-back methods close.
Do retained earnings in my corporation count as income?
At some lenders, yes, with an accountant's letter confirming the money could be withdrawn without harming the business. It is last year's retention that counts, not the accumulated balance on your balance sheet — a figure built up over a decade is not one year of income. On these figures $85,000 of retention is what takes the file from the bank's $350,820 to $752,889. It only applies to incorporated businesses; a sole proprietor already reports business income personally.
How long do I need to be self-employed to get a mortgage?
Two full years for essentially every A-lender. Below that, the bank methods close regardless of income — this page shows them as closed rather than ranking a number you cannot reach. The realistic route under two years is an insured self-employed program or an alternative lender, priced above A-lender rates, with a refinance conversation once the history exists.
What is a stated-income mortgage and would I qualify?
It is an alternative-lender product where you state an income rather than proving it through tax returns — but the lender tests the claim against your gross business revenue at a margin typical for your industry. On these figures the ceiling is $72,000 against $240,000 of revenue, while the documents support $162,700, so a stated claim would be cut by $90,700. That is a signal this file belongs at an A-lender with proper documentation, not an alternative one.
Why does my bank offer me so much less than a broker says I can get?
Because your bank runs one method — the two-year average — and does not run the others. It is not being unreasonable; it is applying its own policy, which is the most conservative of the five. On the default figures that is the difference between $350,820 and $752,889 on identical tax returns. The gap is lender policy, not your finances, and it is not something you can negotiate at the branch.
What documents do I need for a self-employed mortgage?
Two years of complete T1 Generals and Notices of Assessment, plus either corporate financial statements and T2 returns if you are incorporated or two years of T2125 if you are not, business registration or articles of incorporation, six to twelve months of business bank statements, and a CRA statement showing nothing owing. Add an accountant's letter if you are relying on add-backs or retained earnings, and a written explanation if your income declined.
Next step
Your bank runs one of the five methods.
A branch applies its own policy, which is the most conservative treatment of the five, and it has no reason to tell you the other four exist. None of this is published — which lender counts add-backs, which counts retained earnings, and which wants an accountant’s letter phrased a particular way is knowledge, not a rate sheet. Mortgage Directory lists licensed brokers across Canada — placement is never sold, and an enquiry goes to one broker only.
