By any measure, the United States tax code is huge. At the end of 2014, Commerce Clearing House’s Standard Federal Tax Reporter was up to 74,608 pages.1
And each Monday, the Internal Revenue Service (IRS) publishes a 20 to 50-page bulletin about various aspects of the tax code.2
Fortunately, it’s not necessary to wade through these massive libraries to understand how income taxes work. Understanding a few key concepts may provide a solid foundation.
One of the key concepts is marginal income tax brackets.
Taxpayers pay the tax rate in a given bracket only for that portion of their overall income that falls within that bracket’s range.

Seeing how marginal income tax brackets work is helpful because it shows the progressive nature of income taxes. It also helps you visualize how your total tax rate can be calculated. But remember, this material is not intended as tax or legal advice. Please consult a tax professional for specific information regarding your individual situation.
How Federal Income Tax Brackets Work
Say a married couple, filing jointly, in 2018 had a taxable income of $200,000. Each dollar over $165,000 (or $10,000) would fall into the 24% federal income tax bracket. However, the couple’s total federal tax would have been $36,579, or just under 20% of their adjusted gross income.
This is a hypothetical example used for illustrative purposes only. It assumes no tax credits apply.
2018 Federal Income Tax Brackets
Your federal income tax bracket is determined by two factors: your total income and your tax-filing classification.
For the 2018 tax year, there are seven tax brackets for ordinary income — ranging from 10% to 37% — and four classifications: single, married filing jointly, married filing separately, and head of household.
