The T1 General is the standard Canada Revenue Agency personal income tax return that every individual, including the self-employed, files annually, and is one of the core documents a lender reviews to verify income on a mortgage file.
A salaried borrower can usually be verified with pay stubs and a letter of employment, but a self-employed or business-for-self borrower doesn't have those documents in the same form. For that borrower, the T1 General and its schedules, reviewed together with the Notice of Assessment, become the primary way a lender confirms what the borrower actually reported earning.
Because self-employed income can move around year to year, lenders commonly want to see more than a single tax year of T1s to judge whether income is stable, growing, or declining — the exact number of years requested varies by lender and program. Certain non-cash deductions claimed on the T1, such as capital cost allowance, may also be treated as an add-back to qualifying income, subject to the lender's own policy.
Core self-employed document: for business-for-self borrowers, the T1 General and its schedules are typically reviewed alongside the Notice of Assessment to confirm reported income.
More than one snapshot: lenders commonly review more than one tax year of T1s to judge whether self-employed income is stable, growing, or declining.
Add-backs start here: certain non-cash deductions claimed on the T1, like capital cost allowance, may be added back to qualifying income under the lender's own guidelines.
One national form, filed everywhere: every Canadian taxpayer uses the same T1 General package, adjusted for the province or territory of residence, through the CRA.
