Worked Examples
Example 1: Basic Estate Tax Calculation
Problem:An individual dies in 2024 with a $20 million estate. Calculate federal estate tax.
Solution:Total estate value: $20,000,000 Federal exemption (2024): $13,610,000 Taxable estate: $20,000,000 - $13,610,000 = $6,390,000 Federal estate tax (40%): $6,390,000 × 0.40 = $2,556,000 Net to heirs: $20,000,000 - $2,556,000 = $17,444,000 Effective tax rate: $2,556,000 / $20,000,000 = 12.78%
Result:Federal tax: $2,556,000 | Net to heirs: $17,444,000
Example 2: Married Couple with Portability
Problem:First spouse dies in 2024 with $8 million estate, leaving everything to surviving spouse. Surviving spouse later dies with combined $30 million estate. What's the tax?
Solution:First spouse's death: Estate: $8M → to surviving spouse Marital deduction: unlimited (no tax) Unused exemption: $13.61M - $0 = $13.61M (Portability election filed) Second spouse's death: Estate: $30M Own exemption: $13.61M Portable from first spouse: $13.61M Total exemption: $27.22M Taxable estate: $30M - $27.22M = $2.78M Estate tax: $2.78M × 0.40 = $1,112,000
Result:Tax: $1,112,000 (with portability vs. $6,556,000 without)
Example 3: Impact of 2026 Exemption Reduction
Problem:If someone dies in 2026 with a $15 million estate and exemption drops to $7 million (inflation-adjusted), what's the difference vs. 2024?
Solution:In 2024 (current exemption: $13.61M): Taxable: $15M - $13.61M = $1.39M Tax: $1.39M × 0.40 = $556,000 In 2026 (projected exemption: ~$7M): Taxable: $15M - $7M = $8M Tax: $8M × 0.40 = $3,200,000 Difference: $3,200,000 - $556,000 = $2,644,000 more tax! This demonstrates why estate planning now (using current high exemption) is valuable for estates $7M-$14M.
Result:$2.64M more tax if exemption drops in 2026
Frequently Asked Questions
What is estate tax and who pays it?
Estate tax is a federal tax on the transfer of property at death. It's levied on the estate itself before assets pass to heirs. The federal rate is 40% on amounts exceeding the exemption ($13.61 million per person in 2024, $27.22 million for married couples). Only about 0.1% of estates (roughly 2,000 per year) owe federal estate tax. It's sometimes called the 'death tax,' though this is technically a misnomer - it's not a tax on dying but on transferring large wealth.
What is the current estate tax exemption for 2024?
For 2024, the federal estate tax exemption is $13.61 million per individual or $27.22 million for a married couple (with portability). This exemption is indexed to inflation and increases annually. However, this high exemption is temporary - under current law, it's set to drop to approximately $7 million per person (adjusted for inflation) in 2026 when the Tax Cuts and Jobs Act provisions expire, unless Congress extends them.
How can I legally avoid or reduce estate tax?
Common estate tax reduction strategies: Annual gift tax exclusion (give $18,000/year per recipient tax-free in 2024), irrevocable life insurance trusts (remove policy proceeds from estate), charitable donations (unlimited estate tax deduction), spousal transfers (unlimited marital deduction - no tax when passing to spouse), grantor retained annuity trusts (GRATs), qualified personal residence trusts (QPRTs), and family limited partnerships or LLCs. For estates over the exemption, proper planning can save millions in taxes.
What is the difference between estate tax and inheritance tax?
Estate tax is paid by the estate before distribution (federal and 12 states + DC). Inheritance tax is paid by the beneficiary who receives the inheritance (6 states: Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania). Some states have both. Inheritance tax rates vary by relationship - spouses and children often pay less or nothing, while distant relatives and non-relatives pay higher rates. Maryland is the only state with both estate and inheritance taxes.
Do state estate taxes differ from federal?
Yes, significantly. 12 states plus DC have estate taxes with exemptions ranging from $1 million (Oregon, Massachusetts) to $13.61 million (Connecticut, matching federal). State rates range from 10-20%. States with estate tax: Connecticut, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, New York, Oregon, Rhode Island, Vermont, Washington, and DC. Six states have inheritance tax instead. Your state of residence at death determines which applies.
What is portability and how does it work?
Portability allows a surviving spouse to use their deceased spouse's unused estate tax exemption. If the first spouse dies using only $3 million of their $13.61 million exemption, the surviving spouse can use the remaining $10.61 million plus their own $13.61 million, for a total of $24.22 million exemption. However, portability must be elected by filing IRS Form 706 within 9 months of death, even if no tax is owed.
How does life insurance affect estate tax?
Life insurance death benefits are included in your taxable estate if you own the policy. For large policies, this can push estates over the exemption. Solution: transfer ownership to an Irrevocable Life Insurance Trust (ILIT) at least 3 years before death. The ILIT owns the policy, receives death benefits outside your estate, and can use proceeds to pay estate taxes or provide liquidity to heirs. Must be properly structured to avoid IRS challenges.
What is basis step-up and why does it matter?
When you inherit assets, their tax basis 'steps up' to fair market value at death. If someone bought stock for $10,000 that's worth $1 million at death, heirs inherit with a $1 million basis - no capital gains tax if sold immediately. This step-up is a huge tax benefit that partially offsets estate tax. For example, a $20 million estate might include $5 million in unrealized capital gains that disappear through step-up, saving heirs $1 million in capital gains tax (at 20% rate).
Should I gift money now or leave it in my estate?
Gifting considerations: Annual exclusion gifts ($18,000/person in 2024) reduce your estate tax-free. Larger gifts use lifetime exemption but remove appreciation from estate. Downside: you lose access to the money, and recipients get your cost basis (no step-up). For appreciating assets, gifting now removes future growth from your estate. For low-basis assets, keeping them gets heirs a step-up. Strategy depends on asset type, estate size, and your financial needs.
What happens if I don't pay estate tax?
The estate executor is personally liable for unpaid estate taxes. The IRS has up to 10 years to collect (3 years standard, extended if returns aren't filed). They can place liens on property, seize assets, and charge interest and penalties. Estate tax must be paid within 9 months of death, often requiring estate sale or liquidity planning. This is why large estates maintain liquid assets or life insurance to cover projected taxes.
Background & Theory
Estate tax is a complex area of tax law affecting only the wealthiest estates but requiring careful planning to minimize. Understanding how it works helps in estate planning, especially as exemption levels may change.
Federal Estate Tax Structure:
Exemption Amount (2024): $13,610,000 per person
Tax Rate: 40% flat rate on amounts over exemption
Calculation:
Taxable Estate = Gross Estate - Deductions - Exemption
Tax = Taxable Estate × 0.40
What's Included in Gross Estate:
Everything you own or control at death:
- Real estate (primary residence, vacation homes, rental properties)
- Bank and investment accounts
- Business interests
- Retirement accounts (IRA, 401k)
- Life insurance (if you're the owner)
- Personal property (cars, jewelry, art, collectibles)
- Trust assets where you retained control
- Half of jointly owned property with spouse
Common Deductions:
- Marital deduction (unlimited to U.S. citizen spouse)
- Charitable donations (unlimited)
- Debts and mortgages
- Funeral expenses
- Estate administration costs
- State estate taxes paid
Key Estate Tax Concepts:
Portability: Surviving spouse can use deceased spouse's unused exemption. Must file Form 706 to elect, even if no tax owed.
Unified Credit: Estate and gift tax use the same lifetime exemption. Large gifts reduce your available estate exemption.
Step-Up in Basis: Inherited assets get a "step-up" to fair market value at death, eliminating capital gains tax.
Gross vs. Adjusted Gross Estate: Gross estate includes everything; adjusted gross estate subtracts debts and expenses.
