Taxes
Tax calculators estimate what you owe and what you keep. Find your take-home pay, see how the 2026 federal brackets apply to your income, estimate self-employment tax, or add sales tax to a purchase. Retirement tools project a 401(k) or Roth IRA and its tax treatment. Each calculator states the rules and effective date it uses and links to official sources. Results are estimates, not tax advice.
