Frequently Asked Questions (FAQs)

The Marginal Tax Rate is the rate applied to the last dollar of your taxable income (the highest tax bracket you fall into). The Effective Tax Rate is the total tax paid divided by your total taxable income. Due to the progressive system, your effective rate is almost always lower than your marginal rate.

Federal income tax is calculated on your Taxable Income (Adjusted Gross Income minus deductions). This calculator requires Taxable Income because it applies the tax brackets directly. To find your Taxable Income, you must subtract the Standard Deduction (or itemized deductions) from your Gross Income.

A progressive tax system divides income into segments (brackets), each taxed at a different rate. Your income is taxed at the lowest rate up to the first threshold, then the next slice of income is taxed at the next highest rate, and so on. No one's entire income is taxed at their highest marginal rate.
