Marginal Tax Rates: Manitoba 2010

E&Y have analyzed Manitoba tax rates as of 2010-3-31 and we may draw some conclusions from these data:

Investors Taxable Income Marginal Rate on Interest Marginal Rate on Dividends Equivalency Factor
Widows & Orphans $30,000 25.80% 0.00% 1.35
Professionals $75,000 39.40% 15.02% 1.40
Plutocrats $150,000 46.40% 25.10% 1.40

Equivalency factors have declined marginally since my 2006 post on this topic.

Two nuances should be noted. Firstly, E&Y appears to have put a floor of 0.00% on the published marginal tax rate for dividends; in fact, the tax on dividends can be negative if the taxpayer has other income available to soak up the excess dividend tax credit. This will increase the equivalency factor for “Widows & Orphans”.

Secondly, if the taxpayer is subject to OAS clawback, the equivalency factor will decline by about 0.1. It should be noted that this figure is an extremely rough estimate and is based solely on the direct income tax effect – there may be other net-income-tested benefits to the taxpayer, such as drug plans, which will exacerbate the decline.
