How it works

Taxable estate = gross − deductions − 2026 exemption ($15,000,000.00). Tax = taxable × 40% top federal rate. States may impose additional estate/inheritance tax.

Frequently asked questions

Are these amounts an exact tax bill?

No. They use verified 2026 IRS/SSA figures but ignore credits, phase-outs and AMT. Use tax software or a CPA to file.

Marginal vs effective rate?

Marginal is the rate on your next dollar. Effective is total tax ÷ taxable income — always lower because earlier brackets fill first.

Standard or itemized?

Take whichever is larger. 2026 standard deduction: Single $16,100 · MFJ $32,200 · HoH $24,150 · MFS $16,100.

How is state tax handled?

Eight states impose no income tax. The rest are approximated at their top rate — see your state's brackets for a precise figure.
