Estate-tax estimates depend on the selected jurisdiction, tax year, taxable estate and available exclusions. Deductions and prior gifts can change the taxable base.
Example to check
An estate valued at $1,000,000 with $100,000 of eligible deductions has a $900,000 balance before applying any exclusion or tax brackets.
Before using the result
Do not apply a single flat rate to the gross estate. Federal and local rules, marital transfers and prior gifts need professional review; modeled results are planning estimates only.
