Frequently Asked Questions
How do US federal income tax brackets work?
The US uses a progressive tax system with seven brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%). Only the income within each bracket is taxed at that rate, not your entire income. For example, a single filer earning $50,000 pays 10% on the first $11,600, 12% on the next portion, and 22% on the remainder. Our calculator applies the correct brackets for your filing status.
How is self-employment tax calculated?
Self-employment tax covers Social Security (12.4%) and Medicare (2.9%) on net self-employment income. You first multiply net income by 92.35% to get the taxable base. The combined 15.3% rate applies up to the Social Security wage base, and the 2.9% Medicare portion applies to all earnings. An additional 0.9% Medicare surtax applies above $200,000 for single filers.
What is the difference between salary and paycheck calculators?
A salary calculator converts between annual, monthly, biweekly, weekly, and hourly pay rates. A paycheck calculator goes further by deducting federal income tax, state tax, Social Security, Medicare, and other withholdings to show your actual take-home pay for each pay period.
How are capital gains taxed in the US?
Short-term capital gains (assets held under one year) are taxed as ordinary income. Long-term capital gains (over one year) receive preferential rates of 0%, 15%, or 20% depending on your taxable income. High earners may also owe a 3.8% Net Investment Income Tax. Our calculator determines your rate based on filing status and income.
