Worked examples

Calculate an estate before applying the exclusion

Illustrative inputs are specified in the steps below; the example link loads the complete settings. Unmentioned settings use the linked defaults.

  1. With all other assets and deductions zero, 1,000,000 gross assets − 100,000 debts − 10,000 administration expenses = 890,000 taxable estate before exclusion/credit calculations.

Taxable estate: 890,000 USD.

Common questions

Is every estate asset automatically taxable at the top rate?

No. Deductions, the applicable exclusion/credit and prior transfers affect federal liability. Gross asset value alone is not the final tax base.

Why include prior taxable gifts in an estate estimate?

Federal estate and gift calculations are linked. Prior transfers can affect the available exclusion and unified calculation.

Scope and assumptions

This uses the project's documented federal rule version. State estate/inheritance taxes, asset valuation and eligibility for deductions or portability require separate review.
