How to claim

Complete Form T657, Calculation of Capital Gains Deduction, to calculate your capital gains deduction. If you have investment income or investment expenses in any years from 1988 to 2025, you must also complete Form T936, Calculation of Cumulative Net Investment Loss (CNIL) to December 31, 2025.

If you are including a taxable capital gain in your income resulting from a reserve that relates to a disposition in a prior year of capital property that is QSBCS or QFFP, the amount of the capital gains deduction that you can claim is based on the year that the property was disposed of. This also applies to any taxable capital gain allocated and designated to you, by a trust which had claimed a capital gains reserve on a disposition of QSBCS or QFFP in a prior year of the trust.

Under proposed changes, if you are claiming the capital gains deduction in respect of capital gains reported by a partnership you are a member of, or capital gains reported to you on a T3 slip of a trust (such as a graduated rate estate) and the partnership or trust has a fiscal period or taxation year that begins before June 25, 2024, and ends on or after January 1, 2025, and the partnership or trust disposed of QFFP or QSBCS in 2024 before June 25, 2024, you must use Part 1 of “Chart 2025” on Form T657.

Where the partnership or trust disposed of QFFP or QSBCS in 2024 after June 24, 2024, you must use Part 2 of “Chart 2025” on Form T657.

If you are claiming the capital gains deduction in respect of capital gains reported by a partnership or trust that has a fiscal period or taxation year that begins after June 25, 2024, and ends on or after January 1, 2025, and the partnership or trust indicates that the capital gains relate to a capital gains reserve claimed in 2024 in respect of a disposition in 2024, before June 25, 2024, of property that was a QFFP or a QSBCS, you must use Period 1 of “Chart 2024” on Form T657.

Where the partnership or trust indicates that the capital gain relates to a capital gains reserve claimed in 2024 in respect of a disposition in 2024, after June 24, 2024, of property that is QFFP or QSBCS, you must use Period 2 of “Chart 2024” on Form T657.
