Taxes
Tax calculators estimate federal taxes on income and investment gains, for tax planners and anyone checking what a sale or a year of income will actually cost. The Federal Income Tax Calculator applies the current year's brackets to your taxable income after the standard deduction, and adds FICA so the total reflects what actually comes out of earnings. The Capital Gains Tax Calculator estimates the federal tax on an investment gain, applying long-term 0, 15, or 20 percent rates or short-term ordinary rates depending on your holding period and income. The Home Sale Capital Gains Calculator handles the special case of selling your primary home: adjusted basis, the Section 121 exclusion, and the taxable gain that remains. Retirement tax-placement tools, Roth vs Traditional and the Roth Conversion Ladder, are listed below. All figures are estimates for the current tax year, not tax advice.
