How the Math Works

  • Federal tax is calculated progressively by bracket based on taxable ordinary income.
  • Capital gains are stacked on top of ordinary income and taxed by short-term or long-term rules.
  • FICA is calculated separately (Social Security wage base + Medicare, with Additional Medicare thresholds).

Assumptions

  • Tax-year constants in the calculator determine brackets, credits, and deduction values.
  • State tax is estimated using simplified effective rates, not full state-by-state form logic.
  • Credit eligibility and phaseouts are estimated from provided filing inputs.

Worked Examples

W-2 baseline

Single filer, $75,000 wages, standard deduction, no gains.

Shows estimated federal + state + FICA and effective overall rate.

With long-term gains

Add $10,000 long-term capital gains with the same wage income.

Shows how gains stack and how taxable gains differ from ordinary-income tax treatment.

1099 scenario

Switch to 1099 income with the same earnings and no withholding.

Highlights self-employment tax impact and estimated payment planning.

When This Estimate Breaks

  • This is not a substitute for filing software or CPA review for complex returns.
  • Special cases (AMT, multi-state income, major business structures) are not fully modeled.
  • Final liability depends on complete IRS/state form instructions and documentation.

Methodology and Editorial Review

  • Ordinary income, capital gains, and FICA are modeled separately, then combined into total estimated tax burden.
  • Credits are applied in non-refundable then refundable order based on the calculator's tax-year settings.
  • Edge cases (zero income, losses, phaseouts) are validated with targeted unit tests.

Key Terms to Know

Marginal Tax Rate
Tax rate on your last dollar of income. This is your tax bracket (10%, 12%, 22%, 24%, 32%, 35%, or 37% for 2025).
Effective Tax Rate
Total tax divided by total income. Always lower than marginal rate due to progressive tax system. Average American pays 13-14% effective rate.
Standard Deduction
2025: $15,000 (single), $30,000 (married). Automatic reduction in taxable income. About 90% of filers use standard deduction.
Tax Credit
Reduces tax bill dollar-for-dollar. Better than deduction which only reduces taxable income. Refundable credits can result in refund.
AGI
Adjusted Gross Income - total income minus specific deductions like retirement contributions, student loan interest, HSA.

  • Harvest tax losses to offset capital gains
  • Keep receipts for all deductible expenses
