How to Use This Tool

2. List all allowable deductions: funeral expenses, outstanding debts, administrative costs, and qualified charitable donations.

Formula and Logic

The estate tax calculation follows IRS guidelines for federal estate tax liability:

1. Taxable Estate = Gross Estate Value - Total Deductions - Marital Deduction
2. If Taxable Estate is less than or equal to 0, no estate tax is owed.
3. Taxable Amount = Taxable Estate - Applicable Exemption Amount (set by selected year)
4. If Taxable Amount is less than or equal to 0, no estate tax is owed.
5. Federal Estate Tax is calculated using progressive tax brackets (18% to 40%) applied to the Taxable Amount.

Note: This tool calculates federal estate tax only. Some states impose separate estate or inheritance taxes not reflected here.

Practical Notes

Estate tax planning requires attention to these finance-specific factors:

• Federal estate tax exemptions are per individual: married couples can combine exemptions up to double the individual amount via portability.
• Marital deductions are unlimited for assets left to surviving US citizen spouses, but do not apply to non-citizen spouses without a qualified domestic trust (QDOT).
• Annual gift tax exclusions ($18,000 per recipient in 2024) reduce taxable estate if gifts are made during your lifetime.
• State estate taxes apply in 12 states and Washington D.C., with exemptions as low as $1 million in some jurisdictions.
• Valuation dates matter: assets are valued as of the date of death or an alternate valuation date 6 months later.

Frequently Asked Questions

Is this estimate binding for IRS filings?

No. This tool provides a planning estimate only. Final tax liability is determined by the IRS based on filed Form 706 and supporting documentation. Always consult a tax professional for official filings.

Do I need to pay estate tax if my estate is under the exemption limit?

No. Federal estate tax only applies to taxable estates exceeding the applicable exemption amount for the year of death. Estates below this threshold owe $0 in federal estate tax.

Are life insurance proceeds included in gross estate value?

Yes. Proceeds from life insurance policies you own are included in gross estate value, even if the beneficiary is a trust or individual. Policies held in irrevocable life insurance trusts (ILITs) are excluded from your gross estate.

Additional Guidance

For accurate planning:

• Update your estimate annually as exemption amounts adjust for inflation.
• Revalue illiquid assets like real estate and business interests every 3-5 years to reflect current market values.
• Coordinate this estimate with your financial planner or estate attorney to align with your overall wealth transfer strategy.
• Keep records of all deductions for 3 years after filing estate tax returns in case of IRS audit.
