Frequently Asked Questions
What is the difference between marginal and effective tax rate?
Your marginal rate is the tax on your last dollar of income, while your effective rate is the total tax divided by total income.
How do tax brackets work?
Each bracket taxes only the income within that range. Moving into a higher bracket does not increase the rate on all your income.
