- A corporation pays tax on its profit before distributing anything to shareholders.
- The math looks unusual the first time you see it, but it follows a consistent process.
- Eligible dividends — generally paid from income taxed at a corporation's higher general rate — receive a larger gross-up and a correspondingly larger dividend tax credit.
If you own an incorporated business in Ontario and pay yourself in dividends, you've probably noticed your tax slip reports a "taxable amount" that's larger than the dividend you actually received. That's not an error — it's the dividend gross-up and tax credit mechanism, and it exists for a specific reason: to avoid taxing the same corporate profit twice.
Understanding how the gross-up and credit work together helps you make sense of your personal tax return and talk through compensation options with your accountant, without assuming dividends are either a loophole or a penalty. They're neither — they're a deliberate piece of tax design known as "integration."
This guide walks through why the mechanism exists, the steps involved, and what it actually means for an Ontario shareholder at tax time.
Why Dividends Are Taxed Differently Than Salary
A corporation pays tax on its profit before distributing anything to shareholders. If a shareholder then paid full personal tax on top of that, on the same dividend, the same dollar of profit would effectively be taxed twice — once inside the corporation, once again in the shareholder's hands.
Canada's tax system is built to reduce that double taxation through a principle called integration: broadly, whether you earn a dollar of business profit directly or through a corporation and then withdraw it as a dividend, the combined corporate-plus-personal tax is designed to land in a similar range. The gross-up and dividend tax credit are the mechanical tools that make integration work on your personal return.
The Three-Step Mechanism
The math looks unusual the first time you see it, but it follows a consistent process.
| Step | What Happens |
|---|---|
| 1. Gross-up | The actual dividend you received is increased ("grossed up") by a percentage set out in the Income Tax Act, to approximate the pre-tax corporate profit that funded it. |
| 2. Tax on the grossed-up amount | You pay personal tax at your marginal rate on this larger, grossed-up figure — not simply on the cash dividend you deposited. |
| 3. Dividend tax credit | A federal, and separate Ontario, dividend tax credit is then applied against your tax payable, crediting you for tax the corporation already paid on that profit. |
The net result is that your final tax bill on the dividend reflects both the corporate tax already paid and your own personal bracket — not your bracket applied blindly to the full grossed-up amount.
Eligible vs. Non-Eligible: Why the Numbers Differ
Not every dividend is grossed up by the same amount. Eligible dividends — generally paid from income taxed at a corporation's higher general rate — receive a larger gross-up and a correspondingly larger dividend tax credit. Non-eligible dividends — typically paid from income that benefited from the small business deduction and was taxed at a lower corporate rate — receive a smaller gross-up and a smaller credit.
The logic is consistent throughout: less corporate tax already paid means less credit is needed to avoid double taxation; more corporate tax already paid means more credit is warranted. The specific percentages used for each type can change, so always confirm the current figures with your accountant or the CRA rather than relying on a number from a prior year.
What This Means for You in Practice
- You don't need to calculate the gross-up by hand — your T5 slip and tax software apply it, using the rates that apply to the tax year in question.
- A dividend looks larger on paper (the grossed-up amount) than the cash you actually received, which surprises many first-time shareholders reading their return.
- The combined effect of gross-up plus credit generally produces a lower overall tax cost on dividend income than on an equivalent amount of salary, though the exact comparison depends on your total income, your province, and the type of dividend — an accountant can model your specific numbers.
- How you pay yourself from your corporation — salary, dividends, or a mix — is a broader decision than the tax rate alone. It also touches CPP contributions, RRSP room, and other factors worth discussing with your accountant and lawyer when you set up your compensation structure.
Frequently asked questions
Am I being taxed twice because the grossed-up amount is bigger than my actual dividend?
No. The gross-up increases the figure used to calculate your tax, but the dividend tax credit is applied afterward to offset the corporate tax already paid on that profit. The two steps work together — looking at the gross-up alone, without the credit, gives a misleading picture.
Do I need to know which type of dividend I received?
Yes, at least in general terms, because eligible and non-eligible dividends use different gross-up and credit rates. Your T5 slip identifies which type you received, and your tax software applies the corresponding calculation.
Does the dividend tax credit vary by province?
Yes. Ontario applies its own provincial dividend tax credit alongside the federal one, and the two work together in your overall calculation. The rates are set out in Ontario's Taxation Act, 2007, and can change from year to year.
Why would a corporation pay a smaller, non-eligible dividend instead of a larger eligible one?
It usually comes down to what corporate tax rate applied to the underlying profit. Income that benefited from the small business deduction is taxed at a lower corporate rate and is generally distributed as non-eligible dividends — the gross-up and credit are calibrated to match the lower amount of corporate tax already paid on it.
