Compare multiple tax scenarios as columns. Each row lines up like a spreadsheet: income, business expenses, IRA deduction, taxable income, tax by bracket, estimated self-employment tax, payments, and estimated amount due/refund.
Tax bracket detail by scenario
Important assumptions: ordinary income, Roth conversions, interest, dividends, and taxable Social Security shown here are treated as ordinary taxable income. Qualified dividends / long-term capital gains are not separated. Business income is treated as Schedule C-style net income and may trigger self-employment Social Security and Medicare tax. Employee Social Security / Medicare contributions are estimated from W-2 wages. Washington mode models no regular wage/ordinary income tax and does not include Washington capital-gains tax. NYC mode estimates NY State + NYC resident tax using simplified brackets and federal taxable income as the base, so it is useful for rough comparison, not filing. IRA contribution is modeled as deductible only up to the entered amount; it does not enforce compensation limits, age rules, workplace-plan phaseouts, Roth limits, MAGI rules, ACA subsidies, Medicaid, IRMAA, AMT, NIIT, or underpayment penalties.
