Under Section 164(6) of the Income Tax Act (as amended by Bill C-15, effective for deaths on or after August 12, 2024), an Ontario executor can carry back capital losses realized by a Graduated Rate Estate (GRE) within its first three taxation years to offset capital gains reported on the deceased’s final (terminal) tax return. This strategy can recover significant tax dollars, providing executors with much-needed breathing room to sell assets.
When a person passes away in Ontario, the Canada Revenue Agency (CRA) applies a harsh rule known as a “deemed disposition.” 📜 This means the CRA treats all of the deceased’s assets-such as real estate, stocks, and mutual funds-as if they were sold at fair market value on the date of death. If the deceased owned a lucrative stock portfolio in Toronto or a second property in Muskoka, this deemed sale often triggers a massive capital gains tax bill on their final (Terminal) T1 tax return.
But what happens if the stock market crashes or real estate values plummet shortly after the person dies? The estate might sell those assets for much less than their date-of-death value, resulting in a capital loss. Normally, a capital loss can only offset a capital gain. If the estate itself has no gains, that loss is useless. Fortunately, Section 164(6) of the Income Tax Act provides a rescue mechanism. It allows the executor to take the estate’s capital loss and apply it backward to the deceased’s final tax return, securing a valuable tax refund.
Step-by-Step Process for Section 164(6) in Ontario
Executing a Section 164(6) loss carryback requires perfect timing and coordination between the executor, an estate lawyer, and a tax accountant. 🕐 Here is how you execute this strategy.
Step 1: Understand the Baseline Valuation
First, you must determine the exact fair market value of the assets on the date of death. This value becomes the “adjusted cost base” (ACB) for the estate. For example, if the deceased’s stock portfolio was worth $500,000 on the day they died, this amount is reported on their Terminal T1 return, and capital gains taxes are paid based on this figure.
Step 2: Monitor Asset Values During the First Year
As the executor, you must keep a close eye on the market. 🔍 If the value of that stock portfolio drops to $400,000 a few months after death, the estate has an unrealized capital loss of $100,000. You must decide whether to hold the assets and wait for a recovery or sell them to trigger the loss for tax purposes.
Step 3: Sell the Assets Within the First Three GRE Taxation Years
This is a critical step. Following the enactment of Bill C-15 (Budget 2025 Implementation Act, No. 1) on March 26, 2026, the timeline for the 164(6) election has been extended. The estate must be a Graduated Rate Estate (GRE), and the assets must be sold within the first three taxation years of the GRE. This three-year window applies to deaths on or after August 12, 2024, giving executors much more time to liquidate illiquid assets like cottages or private shares without missing the carryback window.
Step 4: File the Estate’s First T3 Tax Return
After the 12-month period ends, your accountant will file the estate’s first T3 Trust Income Tax and Information Return. 📄 On this return, you will report the capital loss generated from the sale of the stocks or real estate.
Step 5: Make the Formal Election
You cannot just assume the CRA will apply the loss backward. The executor must explicitly elect to use Section 164(6). Under the updated rules, this is done by submitting a new prescribed form rather than a simple letter, specifying the exact amount of the capital loss realized during the first three taxation years of the GRE that you wish to carry back to the terminal year.
Step 6: Amend the Terminal T1 Return
Finally, your accountant will submit the prescribed form to amend the deceased’s Terminal T1 return. 💰 By applying the capital loss from the estate’s first three years against the gains reported on the date of death, the CRA will recalculate the tax owed and issue a refund cheque to the estate.
How Much Does it Cost in Ontario?
Using this tax strategy requires specialized accounting knowledge, but the tax savings usually far outweigh the professional fees. 💵
- Accounting Fees (CPA): Preparing the Terminal T1, the Estate T3, and the Section 164(6) election generally costs between $2,000 and $5,000 CAD, depending on the complexity of the portfolio.
- Legal Fees: An Ontario law firm may charge $300 to $600 CAD per hour to advise the executor on the risks of selling assets versus holding them.
- Potential Savings: If you carry back a $100,000 capital loss, it can reduce taxable capital gains by $50,000, potentially saving the estate over $25,000 CAD in terminal taxes (based on top Ontario marginal rates).
| Tax Return Type | Who Files It? | What Gets Reported Here? |
|---|---|---|
| Terminal T1 Return | Executor (on behalf of Deceased) | Deemed disposition at fair market value on date of death |
| Estate T3 Return (Years 1-3) | Executor (on behalf of Estate) | Actual sale of assets within the first three taxation years of the GRE, realizing the capital loss |
| T1 Amendment / Prescribed Form | Executor (on behalf of Deceased) | Application of 164(6) loss to recover terminal taxes paid |
How Long Does the Process Take?
The timeline provides much more flexibility. You have up to three taxation years of the Graduated Rate Estate (for deaths on or after August 12, 2024) to sell the assets. ⌛ Once the estate T3 return and the prescribed election form are filed, processing the Section 164(6) election and issuing the tax refund can take the CRA anywhere from 4 to 8 months.
Frequently Asked Questions (FAQ)
Can I deduct funeral expenses on the T3 return?
No. The CRA explicitly states that funeral and burial expenses are personal expenses of the deceased and cannot be deducted on the final T1 return or the estate’s T3 trust return.
Are the costs to maintain a vacant property deductible?
Generally, no. Property taxes, utilities, and insurance for a vacant house waiting to be sold are considered capital carrying costs. They are not deductible unless the property is actively being rented out to generate income.
Can I carry back a loss to prior years when the deceased was alive?
No. Section 164(6) only allows capital losses realized during the first three taxation years of the estate’s existence to be carried back to the terminal tax year (the year of death). You cannot apply these specific losses to the deceased’s tax returns from two or three years before they passed away.
Can a beneficiary sue me if I sell assets at a loss?
Yes, executors face personal liability. You must weigh the tax benefits of triggering the loss under 164(6) against the risk of angering beneficiaries who wanted to hold the stocks long-term. It is highly recommended to communicate the tax strategy with the beneficiaries and obtain their written consent before selling.
