The Principal Residence Exemption (PRE) Formula and How It Works
When a homeowner in Canada sells their home, any increase in the home’s value is technically a capital gain — meaning the seller could owe tax on part of that profit.
However, the Principal Residence Exemption (PRE) allows most Canadians to avoid paying tax on the sale of their main home. Understanding how this exemption works — and especially the PRE formula — is an important skill for every future tax preparer.
1. What Is the Principal Residence Exemption?
The Principal Residence Exemption (PRE) is a special rule in the Income Tax Act that lets Canadians exclude some or all of the capital gain on the sale of their principal residence (the home they ordinarily live in) from income tax.
To qualify as a principal residence, a property must:
- Be owned by the taxpayer (alone or jointly),
- Be ordinarily inhabited by the taxpayer or their family (spouse, common-law partner, or children), and
- Be designated as the principal residence for one or more years during ownership.
In most cases, people have only one property that qualifies — their main home. But if a taxpayer owns multiple properties (for example, a city home and a cottage), they must choose which property to designate for each year when they sell one.
2. The PRE Formula
When a property has been a principal residence for some but not all of the years it was owned, you need to calculate what portion of the capital gain is exempt.
The formula is: Exempt portion of gain=(Number of years designated as principal residence+1)Total number of years owned×Capital gain\text{Exempt portion of gain} = \frac{(\text{Number of years designated as principal residence} + 1)}{\text{Total number of years owned}} \times \text{Capital gain}Exempt portion of gain=Total number of years owned(Number of years designated as principal residence+1)×Capital gain
Let’s break that down:
- “Number of years designated” → how many years the property was your principal residence.
- “+1” → an extra year that the CRA allows to cover the year of sale or the year you moved between homes (since in that year, you could technically have two residences).
- “Total number of years owned” → from the year you acquired the property to the year you sold it.
- “Capital gain” → the total increase in the property’s value (selling price minus adjusted cost base and expenses).
3. Why Is There a “+1” in the Formula?
The +1 ensures that you aren’t unfairly taxed in the year you move from one home to another.
For example, if you sell your old home and buy a new one in the same year, both can qualify as your principal residence for that year. Without adding 1, one of those years would be left partially taxable. The +1 makes sure that transition year is always fully protected.
4. Example: Applying the PRE Formula
Let’s look at a simple example to see how this works.
Example:
- Mary sells her home and realizes a capital gain of $100,000.
- She owned the property for 20 years.
- She wants to designate 14 years of ownership as her principal residence (perhaps because she owned a cottage she plans to designate for the other years).
Applying the formula: (14+1)20×100,000=1520×100,000=75,000\frac{(14 + 1)}{20} \times 100,000 = \frac{15}{20} \times 100,000 = 75,00020(14+1)×100,000=2015×100,000=75,000
So, $75,000 of the gain is exempt under the PRE.
That means:
- Exempt amount: $75,000
- Taxable capital gain: $25,000 (100,000 – 75,000)
- Since only 50% of capital gains are taxable, the amount added to income is $12,500 (50% of $25,000).
5. Reporting the Sale
When a taxpayer sells their principal residence, the sale must be reported to the CRA — even if the entire gain is exempt.
You’ll need to:
- Report the sale on Schedule 3 – Capital Gains (or Losses), and
- Complete form T2091 (IND) – Designation of a Property as a Principal Residence by an Individual.
If the property was the taxpayer’s principal residence for every year they owned it, the calculation using the PRE formula is not required — you simply disclose the sale and claim the full exemption.
6. Typical Scenarios for New Tax Preparers
In most everyday cases, things are simple:
- A client sells their family home.
- They buy another home in the same year.
- The property was their principal residence the entire time they owned it.
In that case:
- No part of the gain is taxable.
- You only complete the basic disclosure on Schedule 3 and the top section of the T2091 form.
The formula becomes important only in special situations — for example, when the taxpayer:
- Owns more than one property (e.g., a cottage and a city home), or
- Rented out part of the home for certain years.
These cases require more careful analysis and may fall into intermediate or advanced tax preparation work.
7. Key Takeaways
| Concept | Explanation |
|---|---|
| Purpose of PRE | Excludes capital gains on the sale of a principal residence. |
| Formula | (Yearsdesignated+1)÷(Yearsowned)×Capitalgain(Years designated + 1) ÷ (Years owned) × Capital gain(Yearsdesignated+1)÷(Yearsowned)×Capitalgain |
| +1 in formula | Accounts for the year of transition when selling and buying a home. |
| Fully exempt cases | When the property was your principal residence for all years owned. |
| Forms involved | Schedule 3 and Form T2091 (IND). |
| Common outcome | Most homeowners pay no tax when selling their main home. |
8. Final Thoughts
For most Canadians, the Principal Residence Exemption makes selling their home a tax-free event.
As a future tax preparer, it’s essential to understand:
- When the PRE applies,
- How to use the formula correctly, and
- When to recognize situations that require professional advice.
Once you’re comfortable with the basic calculation, review Form T2091 to see how this information is reported — it will give you valuable insight into how the CRA applies the exemption in practice.
Reporting the Sale of a Principal Residence and Claiming the Principal Residence Exemption (PRE)
When a person in Canada sells their home, they may not have to pay tax on the profit (capital gain) from the sale — as long as the property qualifies as their principal residence. This tax break is called the Principal Residence Exemption (PRE).
Let’s go step by step through how this works and what needs to be reported.
1. What Is a Principal Residence?
A principal residence is the home that a person (or their family) ordinarily lives in during the year. It can be a house, condo, apartment, or even a cottage — as long as the person ordinarily inhabits it at some point during the year.
However, only one property per family (spouses and minor children together) can be designated as the principal residence for any given year.
2. Reporting the Sale of a Principal Residence
Before 2016, many Canadians didn’t have to report the sale of their home if it was fully exempt. But now, the Canada Revenue Agency (CRA) requires everyone to report the sale of a principal residence on their income tax return for the year it was sold.
Here’s how it’s done:
- The sale is reported on Schedule 3 – Capital Gains (or Losses) under the “Real estate” section.
- You’ll need to include details such as:
- The year of acquisition
- The proceeds of disposition (selling price)
- A description of the property (for example, “123 Maple Street, Toronto”)
- You’ll also need to complete form T2091 (IND) – Designation of a Property as a Principal Residence by an Individual.
This form lets you officially claim the property as your principal residence and claim the exemption.
If you forget to report the sale, the CRA can deny the exemption — meaning the full gain might be taxable. So this step is very important.
3. How the Principal Residence Exemption Formula Works
The PRE formula is used to determine how much of the gain is exempt from tax.
The formula is: Exempt Portion=Capital Gain×(1+Years Designated as Principal Residence)Years Owned\text{Exempt Portion} = \text{Capital Gain} \times \frac{(1 + \text{Years Designated as Principal Residence})}{\text{Years Owned}}Exempt Portion=Capital Gain×Years Owned(1+Years Designated as Principal Residence)
Let’s break it down:
- Capital Gain: The total profit from selling the property.
(Selling price – Adjusted Cost Base – Selling Expenses) - Years Designated: The number of years you are claiming the property as your principal residence.
- Years Owned: The total number of years you owned the property.
- The “+1”: Added to ensure that the year of moving or changing homes is not unfairly taxed — since it’s possible to have two principal residences in that one year (the one you sold and the one you bought).
4. Example of the Formula in Action
Let’s use a simple example:
- You owned your home for 20 years.
- You decide to designate it as your principal residence for 14 years.
- Your total capital gain from the sale is $100,000.
Applying the formula: (1+14)/20×100,000=15/20×100,000=75,000(1 + 14) / 20 \times 100,000 = 15/20 \times 100,000 = 75,000(1+14)/20×100,000=15/20×100,000=75,000
✅ $75,000 of the gain is exempt from tax under the PRE.
❌ The remaining $25,000 is a taxable capital gain.
Since only 50% of capital gains are taxable in Canada, you would include $12,500 ($25,000 × 50%) in income on the tax return.
5. In Most Cases – It’s Simple!
For most people, this calculation isn’t even necessary. In 90% of cases, homeowners sell one home and move directly into another that becomes their new principal residence.
In those cases:
- You simply report the sale on Schedule 3
- Fill out page 1 of the T2091 to designate the home as your principal residence
- You don’t have to perform the full PRE calculation because the gain is fully exempt
Only when a person owns more than one property (for example, a home and a cottage) does the calculation become more complex — since they have to choose which property to designate for which years.
6. Key Takeaways for Beginners
- Always report the sale of a principal residence on your tax return.
- Use Schedule 3 and Form T2091 to disclose it.
- The PRE formula helps calculate the exempt portion when multiple properties are involved.
- In most everyday cases, the sale is fully exempt, and you only need basic reporting.
- Keep records of purchase and sale dates, prices, and any major improvements.
Tip for new tax preparers:
Get familiar with Schedule 3 and the T2091 form. Even if your clients’ sales are fully exempt, understanding how to report them correctly prevents costly errors and ensures compliance with CRA rules.
Reporting the Sale of a Principal Residence and Claiming the Principal Residence Exemption (PRE)
When Canadians sell their home, they often hear that the sale is “tax-free.”
That’s partly true, but not the full story. The sale of any property — even your home — actually creates a capital gain. What makes it tax-free is a special rule called the Principal Residence Exemption (PRE).
This section will help you understand how the PRE works, what needs to be reported, and why the rules changed in recent years.
1. Why the Sale Must Be Reported
Before 2016, Canadians didn’t have to report the sale of their principal residence at all if it was fully exempt.
Starting with the 2016 tax year, the Canada Revenue Agency (CRA) made it mandatory to report every sale of a principal residence, even if the entire gain is exempt.
Why the change?
The CRA found that some people weren’t reporting property sales correctly — especially when they owned more than one property, such as a home and a cottage. By requiring everyone to report these sales, the CRA can ensure that exemptions are claimed properly and prevent misuse.
2. What Happens When a Home Is Sold
When a home is sold, there are two main tax steps:
- Calculate the Capital Gain:
The capital gain is the difference between the selling price and the home’s adjusted cost base (ACB), minus any selling expenses like realtor commissions or legal fees. Capital Gain=Selling Price−(ACB+Selling Expenses)\text{Capital Gain} = \text{Selling Price} – (\text{ACB} + \text{Selling Expenses})Capital Gain=Selling Price−(ACB+Selling Expenses) - Apply the Principal Residence Exemption (PRE):
The PRE can reduce or eliminate that gain, depending on how long the property was your principal residence.
If the property was your principal residence for every year you owned it, the entire gain is usually exempt from tax.
If it wasn’t your principal residence for all years — for example, you also owned a cottage or rented the home for some time — you’ll need to calculate how much of the gain is taxable.
3. Forms Used to Report the Sale
When reporting the sale of a principal residence, two key forms are used:
- Schedule 3 – Capital Gains (or Losses):
Used to report details of the sale, including:- Description of the property (for example: “123 Main Street, Toronto”)
- Year you bought it
- Year you sold it
- Selling price (proceeds of disposition)
- Form T2091 (IND) – Designation of a Property as a Principal Residence:
Used to officially claim the property as your principal residence and calculate any exempt portion of the gain (if needed).
Even if the gain is fully exempt, both Schedule 3 and Form T2091 must be completed and filed with the tax return for that year.
4. When the Exemption Gets Complicated
For most Canadians, the reporting process is simple.
They own one home, live in it for the entire ownership period, sell it, and buy another. In those cases:
- You report the sale,
- Indicate it was your principal residence for all years,
- And the gain is fully exempt — no further calculation needed.
However, things become more complex when a taxpayer owns more than one property (for example, a house and a cottage).
Each family unit (spouses and minor children together) can only designate one property per year as the principal residence.
If the family claimed the exemption on the cottage for some years, those same years cannot also be claimed for the main home.
This may cause part of the gain on the home to become taxable when it’s eventually sold.
5. Why the CRA Is Strict About Reporting
The CRA’s requirement to report every sale is designed to close the gap between what taxpayers claimed and what was actually reported.
Here’s what used to happen before 2016:
- A family might sell their cottage and tell their accountant, “We want to claim the principal residence exemption so we don’t pay tax.”
- The accountant would apply the exemption, but no form was ever filed.
- Years later, when the family sold their main home, they might claim the full exemption again — even though some of it had already been used.
Because these transactions were never formally reported, the CRA had no way to track which property had been designated as the principal residence for which years.
That’s why reporting became mandatory — every sale must now appear on Schedule 3, whether taxable or not.
6. Simple Case vs. Complicated Case
| Situation | What to Do | Tax Impact |
|---|---|---|
| Sold your only home, lived in it the whole time | Report sale on Schedule 3, complete T2091 | Entire gain exempt |
| Own both a home and a cottage | Must decide which property to designate for each year owned | May have a partial taxable gain |
| Rented out part of your home or used it for business | May need to calculate partial exemption | Some gain may be taxable |
7. Key Takeaways for New Tax Preparers
- Since 2016, every sale of a principal residence must be reported.
- The sale is disclosed on Schedule 3, and the T2091 form is used to claim the exemption.
- The Principal Residence Exemption (PRE) is what makes the gain tax-free — not the sale itself.
- Always ask clients if they’ve ever owned other properties, such as cottages or vacation homes.
- In most everyday cases, the process is simple — you report the sale, note it was the principal residence for all years, and the gain is fully exempt.
8. In Simple Terms
Think of it this way:
Every property sale must now be reported, but not every property sale is taxable.
The CRA wants to see it on the tax return, even if no tax is owed.
For most homeowners, reporting the sale is just a quick formality — but understanding why and how to report it correctly is an essential skill for any new tax preparer.
Example: Reporting the Sale of a Principal Residence on the T1
Once you understand the Principal Residence Exemption (PRE), the next step as a tax preparer is learning how to report the sale of a home and claim the exemption correctly on a Canadian tax return.
Canada requires two main forms for this:
- Schedule 3 – Capital Gains (or Losses)
- Form T2091 (IND) – Designation of a Property as a Principal Residence
Let’s break this down using a simple example.
1. Key Details You Need to Know
Before filling out any forms, gather the following information about the property:
- Property Address: The address of the home sold.
- Year of Acquisition: The year the home was purchased.
- Proceeds of Disposition: The amount the home sold for.
- Ownership Details: Was it owned by a single person or jointly with a spouse/partner?
- Number of Years Designated as Principal Residence: Usually, this is all years the property was the principal residence, unless multiple properties are involved.
2. Filling Out Schedule 3 – Capital Gains
On Schedule 3, you disclose:
- The sale of the principal residence under the “Principal Residence” section.
- Property address and year purchased.
- Proceeds of the sale, i.e., how much the home sold for.
For example, let’s assume:
- Mark sold his home for $897,800
- He has owned it for 10 years
- He designates it as his principal residence for all 10 years
On Schedule 3, you would report the sale proceeds and indicate that the property is being claimed as the principal residence for all years owned.
3. Completing Form T2091
Form T2091 is used to claim the Principal Residence Exemption.
For a simple case like Mark’s:
- Enter the address of the home and the year of acquisition.
- Indicate the number of years the property is designated as a principal residence.
- This form calculates the portion of the capital gain that is exempt under the PRE.
In Mark’s example:
- He owned the home for 10 years.
- All 10 years are designated as the principal residence.
- Therefore, the entire gain is exempt from tax.
The taxable capital gain, in this case, is $0, because the PRE covers the entire gain.
4. Situations That Can Be More Complicated
While most homeowners will only have one property, complications can arise if:
- The taxpayer owns multiple properties (e.g., a home and a cottage).
- Part of the property was used to earn rental income or business purposes.
- The property was owned before 1982, or different family members owned other properties.
In these cases, you may need to allocate the PRE across properties or years, and only part of the gain may be exempt.
For beginners, focus on simple scenarios first:
- One property per family unit
- Owned for the entire period
- No business or rental use
In these cases, reporting is straightforward: enter the sale proceeds on Schedule 3 and designate the property on T2091.
5. Key Takeaways
- Since 2016, the sale of every principal residence must be reported, even if the entire gain is exempt.
- Schedule 3 records the sale and proceeds, while T2091 calculates the PRE.
- For simple cases, the process is quick: report the sale, designate the property as principal residence for all years owned, and the gain is fully exempt.
- More complex cases require careful tracking of years, multiple properties, and partial exemptions.
By mastering this simple example, you’ll be ready to handle most common principal residence sales you encounter as a tax preparer.
New for 2023 & Future Returns: The Property Flipping Rule
Starting in 2023, Canada introduced a new rule regarding the sale of residential properties, often called the property flipping rule. This rule is important for anyone involved in real estate transactions, especially those looking to sell a home shortly after buying it.
What the Property Flipping Rule Means
Before 2023, homeowners could generally claim the Principal Residence Exemption (PRE) when selling a property, which could eliminate or reduce any taxes on capital gains.
However, starting with the 2023 tax year, the Canada Revenue Agency (CRA) will closely examine situations where someone buys a home and sells it within 12 months. In these cases:
- The Principal Residence Exemption cannot be claimed.
- The full profit from the sale is treated as business income, not a capital gain.
- This means the entire gain is taxable, not just 50% as it normally would be for capital gains.
Essentially, if someone is buying a home with the intention of making a quick profit—commonly called flipping—they will now face full taxation on that profit.
Exceptions to the Rule
There are certain situations where this rule does not apply, and the sale may still qualify for the PRE. These exceptions typically involve circumstances beyond the taxpayer’s control, such as:
- Death of the owner
- Separation or divorce
- Personal safety concerns
- Disability or illness
- Employment-related moves
- Bankruptcy or insolvency
- Involuntary disposition, such as expropriation or a natural disaster
These exceptions are meant to protect people who must sell quickly due to life events, rather than those who are attempting to make a profit by flipping homes.
Why This Rule Was Introduced
The CRA implemented this rule to prevent people from abusing the Principal Residence Exemption by claiming a quick-sale property as their primary residence. Before 2023, some individuals were able to buy and sell homes in a short period and claim the PRE, avoiding taxes on profits. The new rule ensures that:
- Only genuine long-term principal residences benefit from the exemption
- Short-term speculative sales are taxed fairly as business income
Key Takeaways for Tax Preparers
- Applies to sales after January 1, 2023: This rule does not affect 2022 or earlier returns.
- Principal Residence Exemption cannot be claimed if the property was held less than 12 months, unless an exception applies.
- Full gain is taxable as business income, not as a capital gain.
- Document exceptions carefully: If a life event forces a sale within 12 months, proper documentation may allow the PRE to apply.
This rule is a reminder that as a tax preparer, you must ask clients about their intentions and the timing of property sales. Knowing whether a client is selling a long-term home or flipping a property is crucial to reporting the sale correctly and ensuring compliance with CRA rules.
