If you change your home into a rental property or vice versa, the CRA deems you to have sold it, triggering immediate capital gains taxes. Filing a Section 45(2) or 45(3) election defers this tax and can extend your Principal Residence Exemption (PRE) for up to four extra years. If you forgot to file, you can submit a late election to the CRA, subject to a penalty of $100 per month up to a maximum of $8,000 CAD.
Real estate investing and homeownership in Canada often involve changing how a property is used. For example, you might move out of your primary home in Toronto to rent it out, or you might move back into an investment condo in Vancouver. Under the federal Income Tax Act, whenever you change the use of a property, the Canada Revenue Agency (CRA) considers you to have sold and repurchased it at fair market value. This “deemed disposition” can trigger a massive, unexpected capital gains tax bill, even if you never actually sold the home or received any cash.
Thankfully, the law provides a vital shield for Canadian property owners. 📜 By filing specific tax elections under Section 45(2) or Section 45(3), you can legally defer these capital gains taxes until you actually sell the property to a third party. However, these elections are a massive target for CRA audits. Because missing the filing deadline can wipe out your tax deferral and your Principal Residence Exemption (PRE), consulting a Canadian tax lawyer from our directory is the safest way to correct past mistakes and defend your filings against aggressive CRA auditors.
Step-by-Step Process for Filing and Defending Section 45 Elections
Navigating the rules for changing property use requires perfect timing and exact documentation. Whether you own a duplex in Halifax or a townhouse in Calgary, the federal rules apply universally. Here is how you manage the process and defend yourself in an audit.
Step 1: Identifying the Change in Use
The first step is determining when the CRA considers the use of your property to have officially changed. 📅 This generally happens on the exact day your former home becomes a completely income-producing rental, or the day your tenant moves out and you move your family in. If you only rent out a small basement suite while still living upstairs, the CRA usually does not consider this a complete change in use, provided you do not claim Capital Cost Allowance (CCA) on the building.
Step 2: Filing the Election on Time
To avoid the deemed disposition trap, you must file a formal letter with your T1 General tax return in the year the change occurs. If you are turning your home into a rental, you file a Section 45(2) election. This allows you to designate the property as your principal residence for up to four additional years, sheltering future growth from capital gains tax. If you are moving into a former rental, you file a Section 45(3) election. It is crucial to remember that you absolutely cannot claim CCA (depreciation) on the property if you want these elections to remain valid.
Step 3: Filing a Late Election Request
If you were unaware of these rules and the CRA is auditing you for undeclared capital gains, you can request a late-filed election. ⚠️ The CRA allows this under their taxpayer relief provisions, provided you pay a strict penalty. Your tax lawyer must draft a detailed submission explaining why the election is late and proving that you did not previously claim CCA on your tax returns. The CRA officer will review the facts and has the discretion to accept or deny the late filing.
Step 4: Filing a Notice of Objection
If the CRA auditor rejects your late election request or arbitrarily assesses you for a deemed disposition, you have the right to fight back. You have 90 days from the date on your Notice of Assessment (NOA) to file a formal Notice of Objection. An Appeals Officer who was not involved in the original audit will review your case. Having legal representation at this stage is highly recommended to present case law supporting your right to the PRE.
How Much Does it Cost to Fix an Election in Canada?
Dealing with the CRA on real estate matters involves late penalties and professional fees, but the cost of doing nothing is far worse. All fees are calculated in Canadian dollars (CAD).
- CRA Late Filing Penalty: The penalty is strictly calculated at $100 CAD per month that the election is late, up to an absolute maximum of $8,000 CAD.
- Capital Gains Tax Savings: A successful late election can easily save you $50,000 to $200,000+ CAD in capital gains taxes.
- Tax Lawyer Fees: Retaining a tax law firm to draft a complex late election or Notice of Objection generally costs between $2,500 and $5,000 CAD.
- Appraisal Fees: If the CRA disputes the fair market value of the property at the time of the change in use, hiring a certified appraiser may cost $400 to $800 CAD.
How Long Does the Process Take?
Resolving a real estate dispute with the Canada Revenue Agency requires patience. ⌛ If you are simply submitting a late election, the CRA’s specialized processing centres may take 6 to 12 months to review the request and issue a penalty assessment. If your case escalates to a formal Notice of Objection, the CRA Appeals division is currently facing massive backlogs as of 2026. It is completely normal for an objection to take 12 to 18 months before an Appeals Officer even contacts your lawyer.
Frequently Asked Questions (FAQ)
What happens if I claimed CCA on my rental?
If you claimed Capital Cost Allowance (CCA) to deduct depreciation against your rental income, the CRA permanently invalidates your right to file a Section 45(2) or 45(3) election. You will lose the ability to shelter the property under the Principal Residence Exemption.
Can I extend the 4-year limit under Section 45(2)?
Generally, the exemption extension is capped at four years. However, if you or your spouse had to relocate for employment and your employer demanded the move, you may qualify for an indefinite extension of the 4-year rule under specific conditions.
Do I have to claim the income while renting it out?
Yes, absolutely. A Section 45(2) election only defers the capital gains tax on the property itself. You are still legally required to report all monthly rental income and deduct your running expenses on your T1 General tax return every year.
Will the CRA audit me if I sell the property later?
Real estate sales are a primary target for CRA audits. When you eventually sell the property and claim the Principal Residence Exemption using Form T2091, the CRA often requests proof that you genuinely lived there and that all proper elections were filed.
Can a tax lawyer guarantee the CRA will accept my late election?
No lawyer can guarantee a result with the CRA. However, a lawyer ensures that your submission strictly complies with the CRA’s taxpayer relief guidelines, maximizing the probability that the Minister will exercise discretion in your favour.
