📐 How We Calculate This
Our calculator uses the latest federal and state tax brackets published by the IRS and state revenue departments. We apply standard deductions, personal exemptions, and marginal tax rates for the current tax year.
Results account for filing status, income level, and applicable credits. We update our tax data within 48 hours of any IRS or state announcements. For complex situations (AMT, self-employment, capital gains), consult a licensed CPA.
