常见问题
What is the difference between marginal and effective tax rate?
Your marginal rate is the tax rate on your last dollar of income. Your effective rate is total tax divided by total income -- it is always lower than your marginal rate.
What is taxable income?
Taxable income is your gross income minus deductions (standard or itemized) and certain adjustments. It is the amount actually subject to tax.
When do tax brackets change?
The IRS adjusts tax brackets annually for inflation. Significant changes occur when Congress passes new tax legislation.
