Question 1

How is take-home pay calculated?

Accepted Answer

Take-home pay is your gross salary minus federal income tax (based on tax brackets and standard deduction), Social Security tax (6.2% up to $176,100), Medicare tax (1.45% + 0.9% above $200K), and state/local income taxes. Our calculator computes all of these automatically.

Question 2

Which states have no income tax?

Accepted Answer

Nine states have no personal income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. However, some make up revenue through higher property taxes, sales taxes, or other fees.

Question 3

Is a higher salary always better if I move states?

Accepted Answer

Not necessarily. A $100K salary in a low-cost, low-tax state can provide more purchasing power than $130K in a high-cost, high-tax state. Always compare take-home pay AND cost of living. Our salary equivalent calculator does this math for you.

Question 4

What’s the difference between marginal and effective tax rate?

Accepted Answer

Your marginal rate is the tax rate on your last dollar earned (the bracket you’re in). Your effective rate is total tax divided by total income — the actual percentage you pay overall. The effective rate is always lower because your first dollars are taxed at lower brackets.

Question 5

Do these calculators account for deductions?

Accepted Answer

Our calculators use the 2026 standard deduction ($15,700 single / $31,400 married). If you itemize deductions, your actual tax bill may be lower. Consult a tax professional for personalized advice.

Question 6

How accurate are state tax estimates?

Accepted Answer

These are estimates based on top marginal rates and simplified effective rate calculations. Actual state taxes depend on specific bracket structures, deductions, credits, and local taxes. Use these for comparison purposes — consult a CPA for exact figures.
