Hm! Trying to understand it! Over here you pay 35% regardless of what you work with or what you earn, but when you go over a limit (which very very few people do) you have to pay 50% tax.
We have bracketed taxable income: Most posters in here fall into the 16-20% tax rate as we don't make more than 165,000 dollars a year. Make 165,000 dollars up into the 280,000 range, you pay 33% or higher. The last tax bracket is anything above the 280,000 (or whatever) range and pay 45% or higher or so. But we have tons of loop holes to avoid paying what the supposed tax bracket suggests.
Please, correct me if I'm wrong.
