2010 Income Tax Brackets

Here are the marginal tax brackets for 2010. Keep in mind that these rates only apply to taxable income. After various adjustments and deductions are calculated, whether you decided to go with standard or itemized deduction, then you can see where you stand within these following brackets. Also keep in mind that aside from federal income tax, there’s also State tax. Usually your state tax + local county tax is around ~5% but you’ll have to check your state for more accurate details.

Please note that these tax brackets are provided for planning purposes. To get a more accurate result, please visit the IRS website and see the office instructions for Form 1040, 1040A, or 1040EZ as appropriate.

Please look over these tax rates so that you can plan accordingly and know what to expect if you owe or you are entitled to receive a refund.

Also I’ve posted additional tax information regarding Social Security and Medicare taxes below.

Social Security tax:
6.2% on earnings up to $106,800 for employees/employers(each)
12.4% on earnings up to $106,800 for self employed

*In 2011 Social Security Tax will get a 2 points reduction bringing it from 6.2% to 4.2% which would let workers keep as much as $2,136*

Medicare Taxes:
1.45% on earnings up to $106,800 for employees/employers(each)
2.9% on earnings up to $106,800 for self employed

  1. Thanks for compiling this data! I’ve been curious about this recently in starting to get my taxes together!
