How long can you spread a capital gain when selling directly to your child?

The default reserve period is five years. Selling directly to your own child extends it, and only when the buyer is your child in person.

Short answer

Up to ten years, not the ordinary five, where the sale is directly to your child. Subsection 40(1.1) extends the ordinary reserve formula wherever “the property was disposed of by the taxpayer to the taxpayer’s child” and the child was resident in Canada immediately before the disposition — but only for qualifying farm, fishing, small-business-corporation and family-corporation property.

The rule: the extended reserve, and who it actually reaches

The ordinary reserve in subparagraph 40(1)(a)(iii) lets a taxpayer defer part of a capital gain over five years as deferred proceeds are collected. Subsection 40(1.1) doubles that period to ten years specifically where the buyer is the taxpayer’s own child, resident in Canada, and the property being sold is qualifying farmland, depreciable farm or fishing property, or shares of a family farm, fishing or small business corporation.

When it changes

A different, separate extended reserve in subsection 40(1.2) applies where shares of a corporation are sold not to the child directly but to another corporation controlled by the child, and the intergenerational conditions in subsection 84.1(2.31) or (2.32) are satisfied. That route only works where the purchaser is a corporation; selling directly to the child in their personal capacity relies on subsection (1.1) instead, and the two are not interchangeable.

Where this played out — Case Files

In one file, the founder sold directly to his daughter rather than to a corporation she controlled, and the advisors had modelled the wrong subsection entirely — the ten-year reserve under subsection (1.1) applied, not the corporation-purchaser route under subsection (1.2).

The Canadian benchmark

What do businesses like this one actually sell for?

Canadian small-business transaction data is not published anywhere, so most valuations in this country quote an American benchmark. The Deavo–Treadstone Acquisition Index is a daily record of Canadian listings built to replace that: asking-price distributions by province and city are published now, and days on market, departure rates and asking-to-sale spreads follow as the series lengthens.
