Read about federal tax brackets posted by on October 23, 2011

Taxpayers generally must self assess income tax by filing tax returns. Most taxpayers won’t need to deal with the 2012 rates until early 2013. A person with $1 million in income, just to take an example, would have their income taxed at all the federal tax brackets. Second, you only incur self-employment tax on your net business income, or what’s left over after you subtract your business expenses. These fluctuations however have the nasty habit of adding up, increasing over the years, when at last you actually notice, and try to keep from fainting. If the tax cuts are not extended, then a reasonable guess can be made.
