Estate Tax (Form 706)
The federal estate tax is a tax on the transfer of property at death. Unlike income tax, which taxes earnings, the estate tax applies to the value of assets a decedent leaves behind. For the 2024 tax year (tested on the May 2025 - February 2026 EA exam), the estate tax exemption is $13.61 million per person.
Understanding the Estate Tax
The estate tax and gift tax work together as a unified transfer tax system. This means lifetime gifts and transfers at death share the same exemption amount. Any exemption used for lifetime gifts reduces the amount available at death.
Key 2024 Figures

Who Must File Form 706?
Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return, must be filed for estates of decedents who were U.S. citizens or residents where the gross estate plus adjusted taxable gifts exceeds the filing threshold of $13,610,000 for 2024.
Important Exception: Even if the estate is below the threshold, Form 706 must be filed to elect portability of the deceased spousal unused exclusion (DSUE) amount.
Filing Deadline
- Due Date: 9 months after the date of death
- Extension: 6-month automatic extension available by filing Form 4768
- Late Filing Penalty: Failure to file may result in penalties of 5% per month (up to 25%)
Components of the Gross Estate
The gross estate includes all property owned or controlled by the decedent at death, valued at fair market value on the date of death (or alternate valuation date).
What's Included in the Gross Estate
| Category | Examples |
|---|---|
| Real Property | Primary residence, vacation homes, rental properties, land |
| Personal Property | Vehicles, jewelry, art, furniture, collectibles |
| Financial Assets | Bank accounts, stocks, bonds, mutual funds |
| Retirement Accounts | IRAs, 401(k)s, pensions, annuities |
| Life Insurance | Proceeds from policies owned by decedent or where decedent had incidents of ownership |
| Business Interests | Sole proprietorships, partnership interests, closely-held stock |
| Jointly Held Property | Full value if decedent provided consideration; 50% for spouses |
| Revocable Trusts | Property in trusts the decedent could revoke or control |
| Powers of Appointment | Property over which decedent held general power of appointment |
Life Insurance Special Rules
Life insurance proceeds are included in the gross estate if:
- The decedent owned the policy (held incidents of ownership), OR
- The proceeds are payable to the decedent's estate
EA Exam Tip: If the decedent transferred a life insurance policy within 3 years of death, the proceeds are still included in the gross estate under the 3-year rule.
Deductions from the Gross Estate
Several deductions reduce the gross estate to arrive at the taxable estate:
Major Deductions
| Deduction | Description |
|---|---|
| Marital Deduction | Unlimited deduction for property passing to surviving U.S. citizen spouse |
| Charitable Deduction | Unlimited deduction for bequests to qualified charities |
| Debts and Claims | Decedent's outstanding debts, mortgages, and valid claims |
| Funeral Expenses | Reasonable funeral and burial costs |
| Administrative Expenses | Executor fees, attorney fees, probate costs |
| State Death Taxes | Deduction for state estate or inheritance taxes paid |
Marital Deduction Requirements
The unlimited marital deduction requires:
- Property passes to surviving spouse
- Surviving spouse is a U.S. citizen (special rules apply for non-citizen spouses using QDOT)
- Property passes in qualifying form (outright or qualifying trust)
Estate Tax Rate Table (2024)
The federal estate tax uses a progressive rate structure. Tax is calculated on the taxable estate amount:
| Taxable Amount | Tax Rate | Tax Calculation |
|---|---|---|
| $0 - $10,000 | 18% | 18% of amount |
| $10,001 - $20,000 | 20% | $1,800 + 20% of excess over $10,000 |
| $20,001 - $40,000 | 22% | $3,800 + 22% of excess over $20,000 |
| $40,001 - $60,000 | 24% | $8,200 + 24% of excess over $40,000 |
| $60,001 - $80,000 | 26% | $13,000 + 26% of excess over $60,000 |
| $80,001 - $100,000 | 28% | $18,200 + 28% of excess over $80,000 |
| $100,001 - $150,000 | 30% | $23,800 + 30% of excess over $100,000 |
| $150,001 - $250,000 | 32% | $38,800 + 32% of excess over $150,000 |
| $250,001 - $500,000 | 34% | $70,800 + 34% of excess over $250,000 |
| $500,001 - $750,000 | 37% | $155,800 + 37% of excess over $500,000 |
| $750,001 - $1,000,000 | 39% | $248,300 + 39% of excess over $750,000 |
| Over $1,000,000 | 40% | $345,800 + 40% of excess over $1,000,000 |
Note: The applicable credit of $5,389,800 effectively exempts the first $13.61 million from tax.
Portability: Deceased Spousal Unused Exclusion (DSUE)
Portability allows a surviving spouse to use the deceased spouse's unused exemption amount, effectively doubling the exemption for married couples.
How Portability Works
- First spouse dies with $5 million taxable estate
- Uses $5 million of $13.61 million exemption
- DSUE Amount: $8.61 million unused
- Surviving spouse can add $8.61 million to their own exemption
- Surviving spouse's total exemption: $13.61M + $8.61M = $22.22 million
Electing Portability
- Must file Form 706 even if no tax is due
- Must file within the filing deadline (including extensions)
- Portability election is irrevocable once made
- Only the last deceased spouse's DSUE is available
EA Exam Tip: Portability is a critical planning tool. Always consider filing Form 706 to preserve the DSUE, even for smaller estates.
Step-Up in Basis vs. Carryover Basis
One of the most significant tax benefits of inherited property is the stepped-up basis:
Comparison
| Transfer Type | Basis Rule | Tax Benefit |
|---|---|---|
| Inheritance | Stepped-up to FMV at death | Capital gains during decedent's life eliminated |
| Gift | Carryover (donor's) basis | Donor's capital gains transferred to recipient |
Step-Up Basis Example
- Decedent purchased stock for $10,000
- Stock worth $100,000 at death
- Heir's basis: $100,000 (stepped-up)
- If heir sells immediately: $0 capital gain
Why This Matters
The step-up in basis eliminates income tax on appreciation that occurred during the decedent's lifetime. This makes holding appreciated assets until death advantageous compared to gifting them during life.
TCJA Sunset: What's Coming in 2026
The Tax Cuts and Jobs Act (TCJA) of 2017 doubled the estate tax exemption. However, this provision is scheduled to sunset after December 31, 2025.
Expected Changes
| Item | 2024 (Current) | 2026 (Projected) |
|---|---|---|
| Estate Tax Exemption | $13.61 million | ~$7 million (adjusted for inflation) |

EA Exam Note: While the EA exam tests 2024 tax law, understanding upcoming changes demonstrates comprehensive knowledge of the transfer tax system.
