how do I figure what tax bracket I my income is taxed at

[TeriH]

Great question!

Tax brackets are confusing.  The federal income tax system is progressive, which means that tax rates go up the greater taxable income you have. The term "tax bracket" refers to the income ranges with differing tax rates applied to each range. When figuring out what tax bracket you’re in, you look at the highest tax rate applied to the top portion of your taxable income for your filing status.

TurboTax has a great article that explains them in depth.  First you need to determine your filing status, (single, married filing joint or married filing separate).  Then it's a matter of looking it up in the tables.
