Methodology
State-tax per-state pages apply the published 2026 bracket schedule, standard deduction, and filing-status rules for the listed jurisdiction. Federal AGI inputs are mapped to state taxable income before bracket math runs. Local taxes (NYC, Philadelphia, certain Ohio cities) are flagged but not embedded in the base estimate.
Assumptions
- The user enters federal AGI, filing status, and state-specific adjustments as provided.
- Brackets, standard deductions, and credits reflect the 2026 statutory values published by the state Department of Revenue and the Tax Foundation.
- Local income taxes and reciprocity-agreement situations are noted but not auto-applied.
Limitations
- These pages do not predict mid-year legislative changes, rate adjustments, or new local tax assessments.
- Multi-state filers, convenience-of-employer rules, and special-circumstance credits require additional tax-professional analysis.
