"What logically should happen is if you receive dividends and the company already paid 30% tax on it, and your personal tax rate is 45%, you should pay only the extra 15% tax. (And it does happen over here in Australia)."

I was skeptical of this claim but Wikipedia confirms - that's an interesting scheme. It basically eliminates taxation as a decision factor in incorporating a company or not. That's interesting, I never heard of such a construct before, although it's quite obvious.

In most of Western Europe, there are different rates for dividend and income tax. So if you own a company, the company first pays e.g. 20% 'profit tax' on it, and then you pay 25% on the dividends; in the end, roughly coming out to the same marginal highest tax bracket for the income tax.
