Unfiled tax returns, a pending tax assessment and an assessed tax balance can each affect the preparation for a mortgage. Establish what is outstanding and which income records are available before relying on an assumed borrowing amount. A different mortgage product does not resolve a tax-filing or payment obligation.
Distinguish unfiled returns, pending assessments and tax owing
A return that has not been filed, a return awaiting assessment and an assessed balance owing are different situations. Tell your accountant or qualified tax advisor which years are involved and what correspondence you have received.
For the financing conversation, explain the purchase you are considering, how you earn income and any dates you are working towards. The aim is to understand the position before making commitments based on an assumed borrowing amount.
Self-employed mortgage records
Documents that support your business income.
Discuss which records are needed for your circumstances before assembling a complete application.
- How you receive income
- Explain how the business operates and how you are paid, including any recent changes.
- Your income records
- Tax returns, Notices of Assessment and business financial statements may help support that explanation.
- Your property, purchase funds and debts
- Include the property you want to finance, funds available for the purchase, and mortgages and other debts you already have.
Understand how tax records support the mortgage income assessment
A lender needs to assess the income supporting the proposed mortgage. For a self-employed borrower, business revenue and personal income are not interchangeable.
CMHC's self-employed programme illustrates the role of documentation. Its published income-verification guidance includes tax records such as a Notice of Assessment with the T1 General and describes documentation for business income, including a Statement of Business or Professional Activities (T2125). It also describes documents relevant to business history and financial stability. This is one programme's framework, not a promise that every lender requires the same records or accepts substitutes for missing returns. Our self-employed financing page explains how business and personal information enter the mortgage discussion.
The records needed depend on the proposed mortgage and how you earn income. Your mortgage advisor can explain which documents support that application and which missing information still needs to be resolved.
Resolve filing and tax-payment issues with a tax professional
Your tax advisor can help determine the filings, information and payments needed. Give your mortgage advisor an accurate account of the outstanding matter so it can be considered alongside your income, other obligations and purchase plans.
CRA's Voluntary Disclosures Program may provide relief for eligible disclosures. Relief is not automatic, and taxes owing still have to be paid. The programme changed for applications received on or after 1 October 2025, so an older article is not a sufficient guide to a current application. Ask your tax advisor whether the programme is relevant before assuming it applies.
Prepare the tax and income information for your mortgage enquiry
You can begin with a short overview:
- Which tax years or assessments are outstanding?
- How do you earn income, and what records are available?
- Is there an assessed balance owing or a payment arrangement to discuss?
- What property decision and timing are you considering?
Keep tax returns, account numbers and other financial records out of the general enquiry message. The team can explain how to provide documents when they are needed.
Coordinate tax preparation with the home purchase timeline
Streetwise can discuss the financing assessment while your tax advisor addresses the tax matter. The assessment needs accurate income records, information about any tax owing and a purchase timeline that allows outstanding matters to be addressed.
If you work for yourself, explore self-employed financing. For the wider purchase decision, explore home financing.
