Estimate your US federal income tax bill. For educational purposes — always consult a tax professional.
The United States uses a progressive tax system — meaning you pay different rates on different portions of your income. You only pay the higher rate on income above each threshold, not on your entire income. This means your marginal rate (the rate on your last dollar) is almost always higher than your effective rate (what you actually pay on average).
Most taxpayers take the standard deduction because it's simpler and often larger than itemized deductions. Itemizing makes sense if your deductible expenses (mortgage interest, charitable donations, state taxes, etc.) exceed the standard deduction amount for your filing status.
