Observations
Data sources. State income-tax rates & brackets: Tax Foundation, 2026 State Income Tax Rates & Brackets. Federal parameters: IRS 2025/2026. Figures are planning estimates — verify before client use. Local/county income taxes (e.g. MD, IN, OH municipalities), some state add-backs/credits, and a few high-income surcharges (e.g. CA 1% MHS, NY recapture) are approximated or excluded. State tax currently uses one 2026 schedule regardless of the selected tax year.
