effective income tax rate. Definition. The actual rate at which a taxpayer pays taxes on income accounting for all taxes and offsets. The rate is calculated by dividing the total of all taxes paid, less offsets, by the total taxable income. The effective rate is typically lower than the tax bracket, which is currently based on a progressive rate scale. For example, a person in the 28% tax bracket who paid a total of state and federal taxes of $13,000 on $100,000 of taxable income has an effective tax rate of 13%.
Average tax rate. Taxes as a fraction of income; total taxes divided by total taxable income. Effective Tax Rate. The tax rate one pays assuming that one pays a flat rate rather than under a progressive system. Under progressive tax systems, one pays different rates for different amounts in income. For example, one may pay 10% for the first $10,000 of income and 25% for all additional income.
