Ontario Budget 2026: The $5,000 Small Business Tax Cut and the Dividend Offset

1. Who qualifies and what it's worth

The headline measure is a one-point cut to Ontario's share of the small business corporate income tax rate — from 3.2% to 2.2% on the first $500,000 of active business income earned in a Canadian-controlled private corporation (CCPC). Combined with the 9% federal rate, the small business combined rate in Ontario would fall from 12.2% to 11.2% on that first $500K.

A few details owners tend to ask about:

• Who qualifies. Any Ontario CCPC earning active business income up to the $500,000 small business deduction limit. Investment income, rental income from a specified investment business, and personal services business income don't qualify — same exclusions that apply to the small business deduction today.
• Effective date. Proposed to take effect July 1, 2026. If your fiscal year straddles that date (say, a March 31 year-end), the rate is prorated across the two periods — 3.2% on income earned before July 1, 2.2% after. Your software or accountant will do the split.
• Maximum savings. 1% of $500,000 is $5,000 per year, per qualifying CCPC — once the rule is in full effect. In the straddle year, you get a fraction of that based on how your fiscal year sits against July 1.
• Scope of the measure. Budget 2026 projects roughly $1.1 billion of relief over three years, covering about 375,000 Ontario CCPCs. Most of those corporations are small owner-managed businesses — not large companies.

If the cut were the whole story, the answer would be simple: every eligible Ontario CCPC nets more money after mid-2026. It's the second change in the same budget package that makes this less straightforward for owner-managers paid mostly in dividends.

2. The offset most owners are missing

Tucked into the same budget paper, the government is also proposing to cut the Ontario non-eligible dividend tax credit — the provincial credit that offsets personal tax on dividends paid out of small-business-rate profits — from 2.9863% to 1.9863% of the grossed-up dividend amount, effective January 1, 2027.

In plain English: Canada taxes dividends using a gross-up and tax credit system. The non-eligible dividend is grossed up by 15% on your personal return, taxed at your marginal rate, and then reduced by federal and provincial credits that are meant to roughly match the corporate tax the company already paid. If the provincial credit shrinks by a point, the after-tax value of a non-eligible dividend falls by roughly 1% of the grossed-up amount — about $1,000 more personal tax for every $100,000 of non-eligible dividend.

Why does this matter? The government is using the credit adjustment as a counterweight. Corporate tax goes down by 1 point at the CCPC level; personal tax on dividends from that CCPC goes up by roughly 1 point at the owner level. The two changes move in opposite directions and, by design, the combined impact is close to neutral for someone who simply receives every dollar of profit as a non-eligible dividend.

But "close to neutral on total tax" and "close to neutral for you specifically" are different things. The timing matters (18 months between the cut and the credit change), the integration math matters (how you're currently paid), and the planning window matters (the credit cut lands on a hard calendar date — January 1, 2027).

3. Salary vs dividends, 2026 vs 2027

The easiest way to see what's happening is to compare all-salary and all-dividend scenarios at three ABI levels, across 2026 and 2027. The numbers below are illustrative — they assume a single Ontario resident with no other income, no RRSP contributions, and the full ABI distributed in the year it's earned. Real files involve brackets, spouses, existing comp mix, and retained earnings. But the directional story is what matters.

Two things to notice. First, salary tax stays roughly flat year-over-year — the corporate rate cut doesn't help you at all if you pay yourself in salary, because salary is deductible to the corporation and never enters the small-business-rate pool. Second, the dividend path gets a little more expensive in 2027 than in 2026 — roughly 1% of the grossed-up dividend amount. At $100K ABI that's $600 or so; at $500K it's around $5,000.

If you're comparing your current compensation mix to the proposed rules, the honest read is this:

• Heavy-salary owners see nothing in either change. Consider revisiting the mix to capture at least some of the rate cut at the corporate level.
• Heavy-dividend owners see a small net improvement in 2026 (rate cut arrives first), then give most of it back on Jan 1, 2027. The 18-month sweet spot is real but it's not a reason to overhaul a plan that already works.
• Mixed-comp owners — the most common setup in Ontario — are mostly unaffected in the aggregate. The rate cut helps the dividend side; the credit cut hurts it. What matters is whether your current mix is right for you in 2027, not whether Budget 2026 forces a change.

4. Status check

Worth repeating plainly: none of this is law yet.

• Ontario Budget 2026 was tabled on March 26, 2026 by the Minister of Finance.
• Bill 97, Plan to Protect Ontario Act (Budget Measures), 2026 — the bill that actually enacts the budget's tax measures — has completed Second Reading and was referred to the Standing Committee on Finance and Economic Affairs.
• No Royal Assent has been given. Rates can move in committee; the effective dates stand until they don't.

If the bill passes without amendment, the July 1, 2026 rate cut and the January 1, 2027 credit change take effect on those dates. If the bill is amended, we'll update this post. Either way, your corporate tax filings should keep using the current 3.2% Ontario small business rate until the legislation receives Royal Assent.

5. What to do before January 1, 2027

You don't need to change anything today. You do need to have the conversation before the December 2026 payroll run, because the credit change lands on a hard date.

1. Check your current compensation mix. Pull your last two T1s and your T4/T5 summaries. How much of your pay came through as salary? Dividends? Shareholder draws that need cleaning up? If you don't know the split cold, that's the first thing to fix — everything else depends on it.
2. Re-run salary-vs-dividend both ways at your ABI level. Once with the proposed 2026 rules (rate cut in, credit cut not yet). Once with the proposed 2027 rules (both changes in). Do it for your actual ABI, not a round number. The answer may be "no change" — but you want to know that before it's too late to act.
3. Lock your 2027 mix before January 1, 2027. If the math says to shift a meaningful portion of your pay to salary, that's a payroll-setup change — talk to your bookkeeper in Q4 2026 so the first January run is already right. If the math says stay on dividends, document the decision with your accountant so you're not re-litigating it next year.

This is the kind of planning work we fold into our corporate tax engagements — we run the comparison at your real numbers, flag where the budget changes actually move the needle, and help you set the payroll and dividend schedule before the calendar flips. If you're an Ontario CCPC and the $5K question is live for your file, it's a 30-minute conversation that pays for itself.
