Does Selling Your Home Affect OAS or GIS in Canada?

For many Canadian seniors, Old Age Security (OAS) and the Guaranteed Income Supplement (GIS) form a critical part of their retirement income. These benefits are income-tested, which means that changes in your reported income — including capital gains from selling a property — can affect how much you receive. If you are a senior in Winnipeg considering selling your home, understanding how the sale might impact your government benefits is essential to making the right financial decision.

The good news is that the principal residence exemption protects most homeowners from capital gains tax on the sale of their primary home. However, there are important exceptions and nuances that every senior should understand before signing on the dotted line. If the property is not your principal residence, or if you have claimed the exemption on another property, the capital gain from the sale could push your income above the thresholds that trigger OAS clawback or reduce your GIS entitlement.

If you are considering downsizing, our Senior Downsizing Checklist for Winnipeg covers all the practical steps, and our guide on using home equity for retirement explores your broader financial options.

How the Principal Residence Exemption Works

When you sell a home that has been your principal residence for every year you owned it, the capital gain is fully exempt from tax under the principal residence exemption. This means the profit from the sale is not included in your taxable income, and therefore does not affect your OAS or GIS. For the vast majority of Winnipeg seniors selling the family home they have lived in for decades, this exemption fully applies and there is no impact on government benefits.

However, you must designate the property as your principal residence on your tax return for the year of the sale. Failing to make this designation — or not being eligible because you designated another property — means the capital gain becomes taxable income. Even a partial gain can be significant on a property owned for many years, and that income spike can trigger benefit reductions.

OAS Clawback: What Triggers It

The OAS clawback — officially called the OAS Recovery Tax — kicks in when your net income exceeds a threshold set each year by the federal government. For the 2025 tax year, the threshold was approximately $90,000. For every dollar of net income above the threshold, 15 cents of OAS is clawed back. At roughly $148,000 in net income, OAS is fully clawed back to zero.

If you sell a property that generates a taxable capital gain — such as an investment property, a cottage, or a home that does not qualify as your principal residence — the taxable portion of that gain is added to your net income for the year. A large enough gain could push you above the clawback threshold, reducing or eliminating your OAS for the following benefit year. The clawback is based on the previous year's tax return, so the impact is felt in the July-to-June payment period after the sale year.

GIS: Even More Sensitive to Income Changes

The Guaranteed Income Supplement is more sensitive to income changes than OAS because it is designed for low-income seniors. GIS is reduced by 50 cents for every dollar of income above the threshold. A taxable capital gain from a property sale — even a modest one — can significantly reduce or entirely eliminate GIS payments for the following year.

For Winnipeg seniors who rely on GIS, the timing and tax treatment of a home sale are critically important. Consulting with a tax professional before selling is strongly recommended, especially if the property is not your primary residence or if there is any question about principal residence eligibility.

Strategies to Protect Your Benefits

If your home sale will generate taxable capital gains, there are strategies to minimize the impact on your benefits. Timing the sale near the end of the tax year can help because the income is reported in that year but the benefit adjustment does not take effect until the following July. If you are selling an investment property, consider whether spreading the gain over multiple years through an installment sale is possible. And always ensure that your principal residence designation is properly filed.

Working with a tax professional who understands the interaction between capital gains and income-tested benefits is the single best investment you can make when planning a home sale as a senior. The cost of professional tax advice is a fraction of the potential benefit loss from poor planning.
