Self employed mortgages in Ontario: the complete guide.

Your accountant did their job and your tax return says you earn a fraction of what the business actually produces. This guide explains the three ways an Ontario lender can calculate your income, which expenses can be added back, exactly what to have ready, and how to plan the two years before you buy.

Talk Through My File Run the Numbers

Section 01

How a lender actually reads self employed income

Three different methods, three different approval amounts, all from the same business.

A salaried applicant hands over a T4 and a letter of employment and the income question is settled in a minute. A self employed applicant hands over a tax return that was legitimately written down to reduce tax, and the lender has to decide what the real, sustainable income is. There are three common methods, and which one a lender uses matters more to your approval than the rate on the page.

Method	What the lender uses	Typically suits
Traditional / line 15000	A two year average of net income reported on your T1 Generals and Notices of Assessment	Sole proprietors who report most of what they earn, and incorporated owners who pay themselves a full salary
Corporate income and add backs	Personal draws plus retained earnings in the corporation, with non cash and discretionary expenses added back	Incorporated professionals and business owners with two years of prepared financial statements
Business deposits / stated income	Six to twelve months of business bank deposits, or a declared income supported by credit strength and down payment	Trades, contractors and service businesses where cash flow is strong but the return is written down hard

Lender policy varies. The same file can produce meaningfully different approval amounts depending on which method the underwriter is permitted to use.

The practical point: being declined once is one lender's policy, not a verdict on your business. The question to ask is which method that lender used, and whether another method fits your file better.

Section 02

Add backs: the expenses a lender may put back into your income

Some deductions reduce your tax bill without reducing the money available to pay a mortgage.

An add back is an expense a lender agrees is not a true drain on your ability to make payments, so it gets added back onto reported income for qualifying purposes. Not every lender allows every add back, and each one has to be visible in the financial statements or the tax return before it counts.

Capital cost allowance, because depreciation is an accounting entry rather than cash leaving the business.
Business use of home, where part of a mortgage, utility or property tax cost you already pay is claimed as a business expense.
Vehicle expenses, in the portion a lender accepts as personal use already funded elsewhere.
One time and non recurring costs, such as a single equipment purchase or a legal matter that will not repeat, when they are documented.
Amortisation of goodwill or intangibles, on the same reasoning as depreciation.

Add backs are argued, not assumed. The lender wants to see the line on the statement, understand why it is not a recurring cash cost, and see the pattern repeat over two years. This is why a prepared file with an accountant's statements usually beats a shoebox of receipts, even when the underlying business is identical.

Section 03

The document list, and why each one is asked for

Complete on day one closes faster than complete on day thirty. Here is the full list.

Income and business

Two years of T1 Generals, all pages, including the statement of business or professional activities.
Matching Notices of Assessment for the same two years, confirming no amounts owing to CRA.
Articles of incorporation, master business licence or HST registration, proving the business exists and how long it has traded.
Two years of corporate financial statements if incorporated, ideally accountant prepared.
Six to twelve months of business bank statements, needed for deposit based programs and often requested anyway.
Current contracts, invoices or a client list where the business is young or the income is project based.

Down payment and property

Ninety days of history on every account the down payment comes from. Lenders trace the source, not just the balance.
A gift letter plus the donor's transfer record where family funds are involved.
Corporate account withdrawals documented as a shareholder draw or dividend, with the tax treatment confirmed.
The agreement of purchase and sale, MLS listing and, for a condominium, the status certificate.

Disclose HST arrears, a CRA payment arrangement, or a recent change in business structure at the first conversation. Raised early, these are usually workable. Discovered at underwriting, they cost you the rate hold and sometimes the deal.

Section 04

Which tier of lender fits your file

Prime, alternative and private are three different products, not three grades of failure.

Tier	What they want to see	Trade off
Prime lenders	Two years of self employment, reported income that supports the payment, strong credit	Best pricing and full insured options, but the least flexibility on how income is calculated
Alternative lenders	Business deposits or stated income, typically 20% or more down, explainable credit history	A rate premium and often a lender fee, in exchange for underwriting that reads the business
Private lenders	Equity in the property above all, with a defined exit plan	Highest cost and short terms, appropriate as a bridge for a specific problem, not a long term home

The right answer is frequently a two step plan rather than a single placement. Take a one or two year alternative term now, report income deliberately over the next tax year, then move to a prime lender at renewal with a file that qualifies conventionally. That path costs something in the short term and saves considerably more over the following decade.

Section 05

A realistic timeline

What to do when, from first thought to closing day.

When	What happens
12 to 24 months out	Decide with your accountant how much income to report. Optimising purely for tax and optimising for a mortgage pull in opposite directions.
6 months out	Stop opening new credit, keep balances low, and keep business and personal banking clearly separated.
3 months out	Assemble the document list. Move down payment funds into one account so the ninety day trail is clean.
Pre approval	Full document review and a rate hold, usually 90 to 120 days. A real pre approval reviews documents; a rate hold alone does not.
Offer accepted	Typically five business days of financing condition. Complete files clear it; incomplete ones ask for an extension.
Closing	Lawyer, land transfer tax, adjustments and keys. Cash requirements are confirmed well before this point.

Section 06

The mistakes that cost self employed borrowers the most

None of these are about the rate.

Applying at several lenders separately. Each application is a credit inquiry, and a cluster of them reads as distress. One broker submission is one inquiry.
Writing income down to nearly nothing in the two tax years before a purchase, then discovering the approval follows the tax return.
Running business expenses through a personal account, which makes deposit based programs impossible to verify.
Taking the lowest rate without reading the penalty clause. A self employed owner who may refinance to pull equity into the business is often better served by a fair payout penalty than by the cheapest posted rate.
Treating a bank decline as final rather than asking which income method was used.

Section 07

Common questions from self employed borrowers

Can I get a mortgage in Ontario if I have been self employed for only one year?

Yes, with the right lender. Two years is the standard, but several Ontario lenders consider one full year when you have prior experience in the same field, strong credit and a reasonable down payment. Expect the file to lean on contracts and business deposits rather than tax returns.

Do self employed borrowers pay higher mortgage rates in Ontario?

Not automatically. If your reported income supports the payment under standard guidelines you qualify at the same rates as a salaried borrower. A premium appears only when the file needs a stated income or alternative lender program, and it is often smaller than people expect.

How much income do I need to show as a self employed borrower?

There is no single figure. Lenders test whether housing costs stay within roughly 39% of qualifying income and total debts within roughly 44%, measured at the stress tested rate rather than your contract rate. The real question is which method a lender uses to arrive at your qualifying income.

Can I use business bank deposits instead of tax returns?

Several lenders offer deposit based programs that average six to twelve months of business deposits. They are common for trades, contractors and service businesses where the corporate return understates real cash flow, and they usually require a larger down payment.

Does incorporating help or hurt my mortgage application?

It can do either. Incorporating lets a lender look at retained earnings and add backs, which often helps. It also means your personal tax return alone understates what the business earns, so a lender working only from line 15000 will read you as earning far less than you do.

What down payment do self employed buyers need in Ontario?

The same rules apply to everyone: 5% on the first $500,000, 10% on the portion between $500,000 and $1.5 million, and 20% above $1.5 million because default insurance is not available. Stated income and deposit based programs typically require 20% regardless of price.

Will HST arrears or a CRA payment plan stop my mortgage?

Not necessarily, but they must be disclosed. Lenders require CRA amounts to be current or cleared at closing, and a documented payment arrangement is far more workable than an arrear discovered during underwriting.

I was declined by my bank. What should I do next?

Find out which income method the bank used before applying anywhere else. A decline based on line 15000 income says nothing about whether a lender that reads corporate income or business deposits would approve the same file, and further scattered applications only damage your credit.
