Uses 2026 federal reference thresholds from IRS guidance and your taxable-income input. State tax, deductions, qualified dividends, AMT, wash sales, collectibles, depreciation recapture, NIIT eligibility, and special asset rules can change the result. The tax year is fixed to 2026 and must be updated when new IRS tables apply. This is an estimate, not tax advice or a filing calculation.
