Can I lose the capital gains exemption by holding too much cash before selling?

The lifetime capital gains exemption rewards owners of active businesses, not owners of cash. A company can be consistently profitable and still fail the tests if it has parked most of its profit on the balance sheet. The CRA describes the exemption as a capital gains deduction for dispositions of qualified small business corporation shares, and whether a company’s shares qualify is decided largely by what its assets are.

What the asset tests count

The Income Tax Act defines a small business corporation as a Canadian-controlled private corporation that meets an asset-value test. At the relevant time, all or substantially all of the fair market value of the company’s assets must be attributable to assets used principally in an active business carried on primarily in Canada, shares or debt of connected small business corporations, or a mix of the two. Cash and portfolio investments are not on that list unless they are used in the business, so they sit on the wrong side of the ratio.

A test at the sale and a test over the years before

The Act takes two different looks. One is taken at the moment of sale and is strict. The other covers the 24 months before the sale and uses a lower threshold, so a large enough cash balance at any point in that window can matter even if it is gone by closing. The Act sets the exact thresholds, which are worth reading in their current form rather than recalling from an old article.

How much cash is too much

The definitions do not name cash or set a dollar figure for it. The question is whether the cash is used in the business or is surplus, and whether cash the operation needs for day-to-day running counts as used in the business is a question of fact for a tax advisor.

Why it is a planning issue, not a closing issue

Because the look-back runs backwards from the sale, last year’s cash position cannot be changed at closing. Removing non-active assets from a company is called purification, and what purification before a sale involves explains the process. The other conditions, including who owned the shares and for how long, are in whether your shares qualify for the exemption.
