The small business rate cut that partly reverses in January

TWO MEASURES moving in opposite directions. The first got the coverage. The second changes what we tell clients.

Ontario has enacted, and Quebec has announced, a cut in the small business corporate income tax rate from 3.2 per cent to 2.2 per cent. Each is accompanied by a reduction in the provincial dividend tax credit on non-eligible dividends, effective for 2027. Money will be cheaper to earn inside the corporation and more expensive to take out of it.

That is integration working as designed, not a clawback. But the two halves run on different effective-date tests, and the eligibility rules behind them diverge more than the identical headline rate suggests.

The corporate side, and why the drafting matters

Ontario cut to 2.2 per cent effective July 1, 2026, prorated for taxation years straddling that date, in Bill 97, which received royal assent on April 24, 2026.

Quebec announced the same 2.2 per cent, reached by raising its small business deduction from 8.3 to 9.3 points against an 11.5 per cent general rate, for taxation years starting after April 29, 2026. No proration.

Take two CCPCs with December 31 year-ends, one in each province, each with $500,000 of active business income, the full business limit available, and in Quebec the further conditions for the maximum rate met. Those assumptions do real work.

The Ontario corporation's 2026 year straddles July 1, so it blends: 181 days at 3.2 per cent and 184 at 2.2, giving 2.6959 per cent provincially and about 11.7 combined with the 9 per cent federal rate. The full 11.2 per cent arrives with the year beginning January 1, 2027.

The Quebec corporation gets no benefit in its 2026 taxation year. That year began January 1, before April 29, so all of it sits at 3.2 per cent. The cut first applies to the year beginning January 1, 2027.

Eligibility diverges, and the assumptions above are where it bites.

Both provinces reduce the $500,000 limit on capital, using the same $10 million and $50 million endpoints, but on different measures and on prior-period amounts under each regime's own timing rules: taxable capital employed in Canada in Ontario, associated-group paid-up capital in Quebec. Quebec adds a grind on adjusted aggregate investment income between $50,000 and $150,000, taking the greater of the two reductions rather than their sum. Ontario expressly does not parallel that federal measure, though the federal rate does, so a passive-income grind can push income to the 15 per cent federal rate while Ontario's 2.2 per cent still applies.

Quebec then conditions the rate itself on something Ontario has no equivalent to. Access to the maximum deduction depends on the proportion of primary and manufacturing sector activity or on remunerated hours, each with its own linear phase-out, and the corporation takes the better of the two. The mechanics are set out in the bulletin and are worth reading rather than summarising. The practical point is that a small Quebec service corporation can end up with a reduced rate, or none of the deduction at all, on facts that would be irrelevant in Ontario.

What changes for 2027

Ontario reduces its credit on non-eligible dividends from 2.9863 to 1.9863 per cent of the grossed-up dividend, effective January 1, 2027. Quebec reduces its rate from 3.42 to 2.69 per cent of the grossed-up amount, for dividends received or deemed received after December 31, 2026.

Against the actual dividend, which is how clients experience it, Ontario's cut is 1.15 per cent of the cash amount and Quebec's a drop from 3.933 to 3.09 per cent. On $100,000 of non-eligible dividends, roughly $1,150 of lost credit in Ontario and $840 in Quebec.

Neither province changed the gross-up, and the federal credit on non-eligible dividends is unchanged at 9.0301 per cent of the taxable amount. Summaries saying "the dividend tax credit drops" describe provincial measures only. Which provincial credit applies generally turns on the individual shareholder's province of residence on December 31, not on where the corporation earned the income.

Why this followed

Integration is the principle that income earned through a corporation and distributed to a shareholder should attract roughly the same total tax as if the individual had earned it directly. The gross-up and credit are calibrated to corporate tax presumed to have been paid, not to what any particular corporation paid.

When the corporate rate falls and the credit does not, the design rationale is that the credit over-compensates relative to the presumed rate, and the reduction is the corresponding adjustment. Whether it over- or under-compensates a given shareholder is a separate question.

It is not a clean correction. The credit applies by the year the dividend is received or deemed received, not by reference to the earnings that funded it, so non-eligible dividends received in 2027 out of pre-cut retained earnings attract the reduced credit on income that bore the old higher rate. The corporate saving accrues as soon as the rate applies; the personal cost only when a non-eligible dividend is paid.

That gap is where the planning sits, and where part two of this two-part series picks up: the arithmetic for a representative owner-manager at several draw levels, what the timing mismatch means for a 2026 dividend decision, and what is worth revisiting before year-end.

This is part one of a two-part series. Part two to be published later this week.
