Line 12000 on your T1 return is where you report the taxable amount of dividends from taxable Canadian corporations.1Canada Revenue Agency. Line 12000 – Taxable Amount of Dividends From Taxable Canadian Corporations The figure you enter is not the cash that hit your account. It’s a higher, “grossed-up” number that stands in for the profit the corporation earned before it paid corporate tax. That distinction surprises many first-time dividend investors, and it changes both your tax bill and your income-tested benefits.
Why the Amount Is Higher Than What You Received
Canada splits dividends from Canadian corporations into two categories. Eligible dividends come from corporations taxed at the general (higher) corporate rate, typically large public companies. Non-eligible dividends come from corporations taxed at the lower small business rate, most often Canadian-controlled private corporations using the small business deduction. Both go on Line 12000, but each uses its own gross-up.
The Income Tax Act requires you to include both the dividend received and an additional gross-up amount when computing income.2Justice Laws Website. Income Tax Act RSC 1985 c 1 5th Supp – Section 82 For eligible dividends, the gross-up is 38%. Receive $1,000 in eligible dividends, report $1,380. For non-eligible dividends, the gross-up is 15%, so $1,000 in cash becomes $1,150 on the return.1Canada Revenue Agency. Line 12000 – Taxable Amount of Dividends From Taxable Canadian Corporations The smaller gross-up on non-eligible dividends reflects the smaller corporate tax that was paid on the underlying profit.
The inflated figure looks alarming on its own. It is offset later in the return by the dividend tax credit, which returns roughly the corporate tax embedded in the gross-up so the same profit is not taxed twice.
Which Slip Boxes Feed Line 12000
The corporation or financial institution that paid the dividend issues a slip showing the taxable (already grossed-up) amount. You total the relevant boxes from every slip and enter that single number on Line 12000. The CRA specifies these boxes:1Canada Revenue Agency. Line 12000 – Taxable Amount of Dividends From Taxable Canadian Corporations
- T5 (Statement of Investment Income): Box 25 for the taxable amount of eligible dividends, Box 11 for non-eligible.3Canada Revenue Agency. T5 Statement of Investment Income – Slip Information for Individuals
- T3 (Statement of Trust Income): Box 50 for eligible, Box 32 for non-eligible. This is the slip you’ll usually see for mutual funds and ETFs held in a non-registered account.4Canada Revenue Agency. T3 Statement of Trust Income Allocations and Designations – Slip Information for Individuals
- T4PS: Box 25 and Box 31, for dividends received through a deferred profit-sharing plan.
- T5013: Box 130 and Box 133, for dividends flowing through a partnership.
Slips are available through your brokerage and through the CRA’s My Account portal. If you received dividends but the payer issued no slip (this can happen when total investment income from a single payer is under $50), calculate the gross-up yourself using 138% for eligible dividends and 115% for non-eligible.1Canada Revenue Agency. Line 12000 – Taxable Amount of Dividends From Taxable Canadian Corporations The income is reportable whether or not a slip arrives on time.
Entering the Total on Your T1
Add every taxable dividend amount from the boxes listed above, across all your slips, and put that combined total on Line 12000 in the Total Income section of the T1. If any of those dividends were non-eligible, put the non-eligible subtotal on Line 12010 as well.1Canada Revenue Agency. Line 12000 – Taxable Amount of Dividends From Taxable Canadian Corporations Line 12000 holds the combined eligible plus non-eligible total; Line 12010 isolates the non-eligible portion so your software can apply the correct dividend tax credit rate to each. Most certified tax software fills in both lines automatically once you key in each slip.
Skipping Line 12010 will not add tax at the reporting stage, but it will keep the software from calculating the right credit later, and that credit is the point of this whole system. The Line 12000 total also flows into Line 15000 (Total Income) and Line 23600 (Net Income), so an error here ripples through the rest of the return.
The Dividend Tax Credit That Offsets the Gross-Up
Reporting more income than you received would be punishing on its own. The federal dividend tax credit, claimed on Line 40425, exists to balance it out.5Canada Revenue Agency. Federal Dividend Tax Credit – Personal Income Tax The rate differs by dividend type: for eligible dividends, the enhanced federal credit works out to roughly 15.02% of the grossed-up amount; for non-eligible dividends the rate is lower, matching the lower corporate tax already paid. Each province and territory adds its own dividend tax credit on top.
The combined effect in most provinces is that eligible dividends are taxed at a noticeably lower marginal rate than wages or interest. In some lower brackets the credit can exceed the tax on the grossed-up amount, leaving eligible dividends effectively tax-free up to a point.
Foreign Dividends Belong on a Different Line
Dividends from non-Canadian companies (U.S. stocks, international ETFs, and the like) do not go on Line 12000. Report them on Line 12100, Interest and Other Investment Income.6Canada Revenue Agency. Line 12100 – Interest and Other Investment Income Foreign dividends are not grossed up and do not qualify for the Canadian dividend tax credit. They’re taxed at your full marginal rate.
Convert foreign dividend income to Canadian dollars using the Bank of Canada exchange rate on the day the income was received. If foreign tax was withheld at the source (the U.S. typically withholds 15% under the tax treaty), do not subtract that from what you report. Claim the foreign tax credit on Line 40500 instead, to recover some or all of the withholding.6Canada Revenue Agency. Line 12100 – Interest and Other Investment Income
Effect on OAS, GIS, and the Canada Child Benefit
The gross-up has a side effect most people don’t see coming. Because the grossed-up figure (not the cash) feeds into your net income, dividends can push you past thresholds for income-tested benefits even when your actual spending power hasn’t changed.
The Old Age Security recovery tax kicks in when net world income exceeds a threshold set annually.7Canada.ca. Old Age Security Pension Recovery Tax You repay 15 cents of OAS for every dollar of net income above that threshold. Because Line 12000 uses the grossed-up amount, a retiree collecting $70,000 in eligible dividends reports $96,600, which is enough to clear the current clawback threshold even though the cash in hand was well below it.
The same principle applies to the Guaranteed Income Supplement for lower-income seniors and to the Canada Child Benefit for families. Both use adjusted family net income, which reflects the grossed-up dividend figure. For someone relying on GIS, even modest Canadian dividend income can reduce monthly payments by more than the after-tax dividend is worth. Families receiving CCB may see their benefit shrink for the same reason. If dividends are a meaningful share of your income, it’s worth asking a tax professional whether holding dividend-paying investments inside a TFSA or RRSP would shelter them from these calculations.
What Happens If You Leave Dividends Off
The CRA matches every T5 and T3 slip issued against the income reported on your return. Miss a slip once and you’ll typically receive a reassessment with interest on the unpaid tax. Miss again within a four-year window and the CRA applies a repeated failure to report income penalty equal to the lesser of 10% of the unreported amount or 50% of the additional tax owing on it.8Canada.ca. False Reporting or Repeated Failure to Report Income That’s the federal penalty; provinces can add their own.
Interest on any balance owing compounds daily from the day after your filing deadline, and the prescribed rate resets each quarter. Before filing, log into CRA My Account and check for any slips you may have missed, especially if you hold investments across more than one brokerage.
