Assumptions on this page. Rates and brackets are 2025 figures for a single filer at age 67, sourced from state revenue departments and the Tax Foundation. Federal tax is excluded, this page is only the state layer. Local and municipal income taxes are not modelled, which understates the bill in states where cities levy their own. Property tax uses the state average effective rate against your home value, so an actual assessment will differ. Sales tax assumes 30% of spending is on taxable goods, a national average that is high for states exempting food and clothing. Age-gated exemptions are applied only when the age qualifies. These are planning estimates, not tax advice. Read the model's limitations.
