How the dividend income calculator works
Updated November 2026
Why dividends are grossed up
A dividend is paid from profit the company already paid tax on. To keep the system fair, your return first grosses the dividend up to roughly that pre-tax profit, taxes it at your rates, and then gives you a dividend tax credit for the company tax already paid. The gross-up is 38 percent for eligible dividends and 15 percent for non-eligible dividends, because the two kinds come from income taxed at different corporate rates.
The steps, in plain words
Four steps, and the calculator above runs exactly these:
Step 1: the taxable amount. Cash dividends times 1.38 for eligible dividends, or times 1.15 for non-eligible dividends. That grossed-up amount is what goes on your return.
Step 2: the credits. The federal dividend tax credit is 15.0198 percent of the taxable amount for eligible dividends and 9.0301 percent for non-eligible dividends. The Ontario credit is 10 percent of the taxable amount for eligible dividends and 2.9863 percent for non-eligible dividends.
Step 3: the tax with and without. The calculator works out your 2026 federal and Ontario tax twice: once on your other income alone, and once on your other income plus the taxable amount, with the credits taken off the second run. Each run uses the real bracket schedules and takes the basic personal amount off at the lowest rate, and no run can go below zero, because the credits are non-refundable.
Step 4: the difference. The tax with the dividends minus the tax without them is the tax your dividends add. Dividing it by the cash you received gives the effective rate.
A worked example
Take the numbers this calculator opens with. Cash dividends of $10,000, all eligible, on top of $60,000 of other taxable income, for 2026 in Ontario.
Step 1: $10,000 times 1.38 gives a taxable amount of $13,800.00, a gross-up of $3,800.00. Step 2: the federal credit is $2,072.73 and the Ontario credit is $1,380.00, for total credits of $3,452.73. Steps 3 and 4: the dividends add $756.27 of federal tax and -$117.30 of Ontario tax. The Ontario slice is negative because the Ontario credit, 10 percent of the taxable amount, is worth more than the Ontario tax on that slice at this income, so it lowers the tax on the other income too. The total tax on the dividends is $638.97, an effective rate of 6.39 percent on the cash, and you keep $9,361.03 after tax. Change any one input and every one of those numbers moves; that is what the fields above are for.
How to read your result
The tax on your dividends is the headline: what the dividends add to your 2026 federal and Ontario tax bill, after both credits. The effective rate puts that tax against the cash you actually received, which is the fair way to compare dividends with interest or salary. The taxable amount still matters on its own: it is the figure that counts as income on your return, even though the cash was smaller. Test your other income a bracket higher and lower before you trust one answer, because the dividends land on top of it.
What the math takes as given, and what it leaves out
The math covers federal and Ontario income tax for 2026, with the basic personal amount as the only other credit, at its full amount for every income. It leaves out the Ontario surtax, the Ontario Health Premium, the Ontario tax reduction, and every other credit and deduction. It leaves out the high-income reduction to the federal basic personal amount. It covers one kind of Canadian dividend in a taxable account: foreign dividends get no gross-up and no credit, and dividends inside a TFSA or RRSP are not taxed this way at all. Your real return can differ, so treat the result as an estimate, not a filing.
The record-keeping side of the same dividends
Tax is only half the work. The other half is knowing what each holding paid, when the next payout lands, and what your yield on cost really is. The Kollaz Money guide Dividend Income Tracker: Worked Example walks through that record-keeping with real numbers. And if your room allows it, sheltering the dividends beats trimming their tax: the free TFSA contribution room calculator works out how much room you have.
