A practical file-preparation guide for sole proprietors, incorporated owners and commission earners who need a mortgage in Ontario.
Four points to remember
- Tax returns and Notices of Assessment are a common starting point, not the only possible evidence.
- Business history, deposits, contracts and financial statements may help explain income stability.
- Tax deductions can reduce the income visible to a traditional lender.
- The cleanest strategy is chosen after reviewing both personal and business documents.
Define the income structure
Identify whether the borrower is a sole proprietor, partner, incorporated owner, contractor or commission earner. Clarify salary, dividends, net business income and any recurring income from other sources. The lender must understand how money moves from the business to the household.
- Business legal structure
- Ownership percentage
- Salary and dividends
- Net business income
- Length of time in business and prior related experience
Build the core document package
A common starting package includes two years of T1 Generals and Notices of Assessment, confirmation that taxes are paid, business registration or incorporation records, and recent personal and business bank statements. Requirements vary by lender and program.
- T1 Generals and NOAs
- T2125 statements where applicable
- Business financial statements
- GST/HST returns or business licence
- Contracts, invoices and active bank statements
Explain income rather than overstating it
Some programs may consider a permitted gross-up or add-back of eligible expenses, while other lenders rely on reported taxable income or business financial statements. The adjustment must be supported and accepted; it should never be assumed in an online calculator.
- Reconcile deposits to invoices or statements
- Separate one-time revenue from recurring revenue
- Explain unusual expenses
- Identify retained earnings and business obligations
- Keep personal and business spending distinct
Compare lender routes
An insured, prime, alternative or private lender may use different documentation and pricing. The best route depends on down payment, property, credit, reported income, business stability and timing. A higher-rate solution should be compared with the cost of waiting and improving the file.
- Insured program where eligible
- Traditional income qualification
- Alternative documentation program
- Short-term private option only with a clear exit
Prepare six to twelve months before buying
Self-employed applicants benefit from planning before the purchase. Tax decisions, business borrowing and large transfers can affect qualification and down-payment verification.
- Step 1: review tax returns and NOAs
- Step 2: clear tax arrears or document a payment plan
- Step 3: organize business statements
- Step 4: calculate using defensible income
- Step 5: protect credit and down-payment history
- Step 6: update the file before making an offer
Frequently asked questions
How many years of self-employment do lenders want?
Two years is a common benchmark, but CMHC notes that flexible options may exist for recently self-employed borrowers with supporting factors and relevant prior experience.
Can lenders add back business expenses?
Some programs may gross up income or add back eligible deductions when properly documented. The permitted treatment varies by lender and insurer.
Can an incorporated business owner use retained earnings?
Some lenders may consider company financial strength or retained earnings under specific policies, but ownership, access, business obligations and accountant-prepared documents must be reviewed.
