There are three sets of tax tables on this page. The first are the standard IRS tax tables demonstrating your marginal tax rates by marital status. The second are these same tables adjusted for your social security and medicare taxes if you are an employee. The third set are tax tables adjusted for an independent contractor, practice owner, or partner in which you pay both the employee and the employer portions of the payroll taxes, reduced by the self-employment tax deduction. If you wish to calculate your true marginal tax rate, be sure to add in your state and local income tax marginal rates.
Remember to use the 2011 Tax Brackets to calculate tax due in April 2012.

So far so good. We’ve all seen these before. But what happens if you adjust them for those additional taxes you see come out of each paycheck-your social security and medicare taxes?

Looking at the tax brackets in this way, you realize just how high your marginal tax rates can be, and this doesn’t even include state and local taxes. It also displays the regressive nature of the payroll taxes. Although lower earners get more relative benefit from social security, many actually pay more in social security tax than in federal income tax, especially after all the deductions and credits they qualify for. It is interesting to note that the $100,000 earner and the $350,000 earner (single) have about the same total marginal tax rate. Keep in mind that these tax rates are 2% lower than they would be without the special payroll tax cut implemented in 2011 (and so far extended through February 2012). Also, note that if there are two earners, you can add 4.2% to the married tax brackets up until both earners hit the $110,100 limit. But what if you are self-employed? Well, things get worse.

These tables include the employee and employer portion of social security and medicare taxes, reduced by the self-employment tax deduction. The alarming size of the “donut hole” is impressive. A single taxpayer earning $87,000 has a higher marginal tax rate than a star NFL quarterback. Likewise, a married taxpayer earning $37,000 in taxable income pays at a higher marginal rate than one with ten times the taxable income. What’s the moral of the story? Get to that $106,800 limit as quickly as possible to lower your marginal tax rates.


Don’t forget to add the often missed yearly 3-4% inflation tax on the money you have earned purchasing power.
Can you comment on if/how the amt has affected you in your career and whether there is anything that can be done in advance to becoming an attending that young doctors should know about?
The AMT hasn’t yet struck me. Keeping your taxable income low by maxing out retirement accounts can help a great deal.
