Ah, hang on, disregard previous post, I leapt to a conclusion (that you were miscalculating the surcharge) before reading the whole chapter.
Dividends from Canadian companies are indeed grossed up by 1/4th for inclusion in taxable income. HOWEVER, there is a tax credit of 16.67% of the pre-grossed up dividend. The net result is a tax savings. Tax credits are (dollar-for-dollar) more valuable than deductions, since the tax credit is applied directly to the tax, not to the income.
Example:
Assumptions: Income of CAD 125,000
Dividend of CAD 1000
Tax on CAD 125,000 = CAD 30,000
Marginal Tax rate = 29% (federal only)
Suppose no gross-up and just added to income:
Dividend = CAD 1000
Income = CAD 125,000
Total = CAD 126,000
Tax = CAD 30,000 + 29% x 1000 = CAD 30,000 + CAD 290 = CAD 30,290
OK, now the actual handling:
Dividend = CAD 1000
Gross Up added to income = CAD 1250
Other income = CAD 125,000
Total Income: CAD 126,250
Tax (from prior example) = CAD 30,000 + 29% x 1250 = 30,362
Tax Credit: 16.67% X 1000 = CAD 167
Total tax: CAD 30,195
So, in this example, the tax on the $1000 dividend is only $195, not $290 as it would be without the complexity.
Even if you’re at the lower marginal rate of 26%, it would work out well, since 1.25% x .26 - .1667 = .1583 is still less than the marginal rate of 26%.
HOpe that helps, and sorry for my earlier assumption.
