How to carry back a capital loss for a tax refund – MoneySense

It sounds like you are aware that you can carry back capital losses, Ramesh. If you have a net capital loss on your 2023 tax return, you can carry it back up to three years. So, you can ask the Canada Revenue Agency (CRA) to apply that loss to capital gains you had in 2022, 2021 or 2020.

When should you carry back a capital loss?

You can apply some or all of the loss to one or more of those years. If you had capital gains in more than one of the past three years, there are three primary considerations.

1. 2023 is the final year you can carry back losses to 2020. In 2024, the furthest you can carry back a capital loss is 2021.

2. If you had a high income in one of those three years, you might be better off carrying the loss back to the year with the highest income. That way, you can maximize the resulting tax refund.

3. If your income and tax rate were relatively low in one or more of the past three years, you might want to defer claiming the loss. Capital losses can be carried forward indefinitely to use against capital gains in a future higher-income tax year.

You are not restricted, Ramesh, to claiming a capital loss on securities against a capital gain on securities. So, in your case, you could carry back a capital loss on securities to claim against a previous capital gain on a rental property.
