Can I still qualify for the capital gains exemption if I only owned my shares for a short time before selling?

Possibly not, and this is a common trap for owners who recently reorganized, incorporated, or acquired their shares shortly before a sale. Qualification for the exemption looks not just at the moment of sale but at how the corporation's assets were used, and who owned the shares, over a preceding period of time — a very recent share issuance or transfer, or a recent corporate reorganization, can mean that history hasn't accumulated yet, which can prevent the shares from qualifying even if everything about the business itself looks perfectly eligible today.

This comes up often after an estate freeze, a recent incorporation of a previously unincorporated business, or a transfer of shares to a new family member shortly before a deal. The specific holding-period and asset-use requirements are detailed and fact-specific, so whether a short ownership window actually disqualifies your particular shares depends on exactly what happened, and when, in the lead-up to the sale.

Because timing is central to this test, reviewing your corporate and share history with a tax advisor as early as possible in a sale process — ideally before you're already committed to a closing date — gives you the best chance to address any gap.
