Tax Model & Calculation Logic

Estimates use 2024 US federal brackets with optional state taxes. Income is taxed progressively, incorporating standard or itemized deductions before calculating liability. Payroll taxes (Social Security and Medicare) are handled separately with wage base limits, delivering effective rate, marginal rate, and take-home pay outputs.

  • Flexible Income Mix

  • Deductions & Credits

    Support for standard or itemized deductions plus child and education credits.

  • Filing Status Comparisons

    Switch between single, married joint, married separate, or head-of-household rates and deductions.

Frequently Asked Questions

Does the calculator include AMT or NIIT?

Alternative Minimum Tax (AMT) and Net Investment Income Tax (NIIT) are not included yet—advanced options are coming soon.

How do I configure state taxes?

Choose a preset rate or provide your own value in settings, and the model layers it onto federal liability.

What is the difference between withholding and estimated tax?

This tool estimates total tax for planning purposes; payroll withholding must still be calculated according to your pay schedule.
