Frequently Asked Questions

What is the 2026 estate tax exemption?

For 2026, the federal estate tax exemption is $15 million per individual. Married couples can combine exemptions through portability for a total of $30 million. Estates below these thresholds owe no federal estate tax.

Individual exemption: $15 million (2026), indexed for inflation from 2027
Married couple with portability: $30 million combined
Less than 0.1% of estates owe federal estate tax
The scheduled 2026 drop to ~$7 million was repealed - the $15M exclusion is permanent
Portability must be elected on first spouse's estate tax return (Form 706)

Filing Status	Exemption Amount	Estate Tax on $20M	Estate Tax on $40M
Single / Widowed	$15,000,000	$2,000,000	$10,000,000
Married (with portability)	$30,000,000	$0	$4,000,000

What is the federal estate tax rate?

The federal estate tax rate is 40% on amounts exceeding the exemption. For example, a $20 million estate (single) would owe 40% on $5 million ($20M - $15M exemption) = $2,000,000.

Estate Value (Single)	Amount Over Exemption	Estate Tax (40%)	Effective Rate
$14,000,000	$0	$0	0.0%
$16,000,000	$1,000,000	$400,000	2.5%
$20,000,000	$5,000,000	$2,000,000	10.0%
$30,000,000	$15,000,000	$6,000,000	20.0%
$50,000,000	$35,000,000	$14,000,000	28.0%

What is the unlimited marital deduction?

Assets left to a surviving U.S. citizen spouse are not subject to estate tax, regardless of amount. This allows deferral of estate taxes until the surviving spouse's death.

Unlimited amount can pass to a surviving U.S. citizen spouse tax-free
Non-citizen spouses: limited to a $194,000 annual exclusion (2026)
Qualified Domestic Trust (QDOT) required for non-citizen spouses
Defers tax only — survivor's estate may owe tax at their death
Consider using bypass/credit shelter trust to preserve both exemptions

What qualifies for estate tax deductions?

Deductible items include: debts and mortgages, funeral expenses, estate administration costs, charitable bequests, and amounts left to a surviving spouse.

Debts and mortgages: reduce gross estate dollar-for-dollar
Funeral expenses: typically $7,000-$15,000 deductible
Charitable bequests: unlimited deduction for qualified charities
Administrative costs: attorney fees, executor fees, appraisals
State estate taxes paid are deductible on the federal return

Do states have separate estate taxes?

Yes, 12 states and DC have state estate taxes with lower exemptions (often $1-5 million). States include: WA, OR, HI, MN, IL, MD, VT, CT, NY, MA, ME, and RI. Check your state's specific rules.

State	Exemption	Top Rate	Notes
Massachusetts	$2,000,000	16%	Lowest exemption in US
Oregon	$1,000,000	16%	Lowest exemption in US
New York	~$7M, indexed annually	16%	Cliff: lose exemption if estate > 105%
Washington	$2,193,000	20%	Highest state rate in US
Connecticut	$15,000,000	12%	Matches the federal exclusion
DC	$4,710,800	16%	Adjusted annually

How can I reduce estate taxes?

Strategies include: annual gift exclusion ($19,000/person in 2026), irrevocable life insurance trusts (ILIT), charitable trusts, family limited partnerships, and using the full exemption during lifetime.

Annual gift exclusion: $19,000/person/year (2026) — tax-free to unlimited recipients
ILIT: removes life insurance proceeds from taxable estate
Charitable Remainder Trust: income stream + tax deduction + charity benefit
Grantor Retained Annuity Trust (GRAT): transfer appreciation tax-free
Family Limited Partnership: 20-35% valuation discounts on transferred interests
Lifetime gifts using exemption: the $15M exclusion is permanent, so gift on your own timetable

Formulas Used

Taxable Estate

Taxable Estate = Gross Estate - Debts - Funeral Costs - Charitable Gifts - Marital Deduction

Calculates the estate value subject to potential tax after all allowable deductions.

Where:

Gross Estate= Total value of all assets (real estate, investments, business interests, life insurance, etc.)

Marital Deduction= Unlimited deduction for assets left to surviving U.S. citizen spouse

Federal Estate Tax

Estate Tax = Max(0, Taxable Estate - Exemption) x 40%

The federal estate tax rate is a flat 40% on the amount exceeding the exemption.

Where:

Exemption= $15,000,000 per individual; $30,000,000 for married couples with portability (2026)

40%= Federal estate tax rate applied to amounts over the exemption

Net to Heirs

Net to Heirs = Gross Estate - Total Deductions - Estate Tax

The amount beneficiaries actually receive after deductions and taxes.

Where:

Total Deductions= Sum of debts, funeral costs, charitable gifts, and marital deduction

Estate Tax= Federal estate tax owed (if any)

Federal Estate Tax: Exemptions, Rates, and Planning Strategies

How the Federal Estate Tax Works

Fewer than 0.1% of U.S. estates owe any federal estate tax under the $15 million exemption that applies in 2026. The tax reaches only the portion of a taxable estate above that threshold, at a flat 40%. For a single filer with a $20 million taxable estate, $5 million is subject to tax, producing a bill of $2,000,000 — an effective rate of 10% on the estate as a whole.

The taxable estate is calculated by subtracting allowable deductions from the gross estate. Gross estate includes real property, bank accounts, investment portfolios, business interests, life insurance proceeds, and retirement accounts. Deductions include debts, funeral expenses ($7,000–$15,000 typical), charitable bequests, and the unlimited marital deduction for assets left to a surviving U.S. citizen spouse.

Married couples can effectively double their exemption to $30 million through portability — but only if the executor files Form 706 for the first spouse’s estate, even when no tax is due. Missing this filing permanently forfeits the unused exemption.

*Based on the 2026 federal exclusion of $15M per individual
Estate Value (Single)	Taxable Amount	Estate Tax (40%)	Effective Rate
$14,000,000	$0	$0	0.0%
$16,000,000	$1,000,000	$400,000	2.5%
$20,000,000	$5,000,000	$2,000,000	10.0%
$30,000,000	$15,000,000	$6,000,000	20.0%
$50,000,000	$35,000,000	$14,000,000	28.0%

The Sunset That Never Arrived

The Tax Cuts and Jobs Act doubled the estate tax exemption from roughly $5.5 million to $11.18 million in 2018, and inflation adjustments carried it to $13.99 million by 2025. That provision was scheduled to expire on January 1, 2026, cutting the exemption roughly in half — and for years, planning advice was built around beating that deadline. It did not happen. Section 70106 of the One Big Beautiful Bill Act set the basic exclusion at $15 million for 2026, made it permanent, and indexes it for inflation from 2027 onward.

For anyone who rushed lifetime gifts to get ahead of the deadline, nothing is lost: Treasury Regulation 20.2010-1(c) already guaranteed that gifts made under a higher exemption are never clawed back. What has changed is the urgency. An estate worth $12 million owes $0 today and would have owed roughly $2 million under the reversion, so the gifting decision can now be made on its merits and on your own timetable rather than against a clock.

The planning that still matters is procedural. Couples relying on portability must confirm Form 706 was filed for any deceased spouse — that filing is what preserves the unused exemption, and the deadline for it has nothing to do with the sunset that was repealed. Trusts and beneficiary designations written to trigger at the old threshold are worth re-reading, since some of them now distribute differently than their authors intended.

Tip: The $15M exclusion is permanent and indexed from 2027, so lifetime gifting no longer races a deadline. Check instead that Form 706 was filed for a deceased spouse - that is what preserves portability.

State Estate Taxes: The Second Layer

12 states and the District of Columbia impose their own estate taxes, often with exemptions far below the federal level. Oregon and Massachusetts have the lowest exemptions at $1 million and $2 million respectively, meaning estates that owe zero federal tax can still face state bills of $100,000 or more.

Washington state levies the highest top rate at 20%, while most other states cap at 12–16%. New York applies a particularly harsh "cliff" rule: if an estate exceeds 105% of the state exemption — roughly $7 million, indexed each year — the entire amount, not just the excess, becomes taxable. Crossing that line by a few thousand dollars can cost hundreds of thousands in state tax, so confirm the current year's figure with New York before cutting it close.

Six states (Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania) also impose separate inheritance taxes, which are paid by the recipient rather than the estate. Maryland is the only state with both an estate tax and an inheritance tax. Use a budget calculator to plan for these potential liabilities when managing an inherited estate.

*Federal figures are 2026; state exemptions are set per state and change annually
State	Exemption	Top Rate	Key Note
Oregon	$1,000,000	16%	Lowest exemption in U.S.
Massachusetts	$2,000,000	16%	No inflation adjustment
New York	~$7M, indexed annually	16%	Cliff at 105% of exemption
Washington	$2,193,000	20%	Highest top rate nationally
Connecticut	$15,000,000	12%	Matches the federal exclusion

Tax Reduction Strategies by Estate Size

$19,000 per recipient per year — that is the 2026 annual gift exclusion amount, and it is the simplest estate-reduction tool available. A couple with three children and six grandchildren can transfer $342,000 annually ($19,000 × 9 recipients × 2 donors) without touching their lifetime exemption. Over 10 years, that removes $3.42 million from the taxable estate.

For estates between $15 million and $30 million, the question is no longer beating a deadline — the exclusion is permanent — but whether to move appreciating assets out early. Irrevocable trusts such as Grantor Retained Annuity Trusts (GRATs) and Spousal Lifetime Access Trusts (SLATs) transfer future appreciation out of the estate while retaining some access to the assets, which matters more the faster an asset is growing.

Estates exceeding $20 million benefit most from Family Limited Partnerships (FLPs) and Charitable Remainder Trusts (CRTs). FLPs can achieve 20–35% valuation discounts on transferred interests, while CRTs provide an income stream to the donor, a charitable deduction, and ultimately benefit a qualified charity. An investment calculator can help model how these strategies affect long-term portfolio growth.

Annual gifts of $19,000/person/year — removes $342,000+/year for a couple with 9 recipients
Irrevocable Life Insurance Trust (ILIT) — removes life insurance proceeds from taxable estate entirely
Grantor Retained Annuity Trust (GRAT) — transfers asset appreciation tax-free over a 2–10 year term
Charitable Remainder Trust (CRT) — provides income stream + estate tax deduction + charity benefit
Family Limited Partnership (FLP) — achieves 20–35% valuation discounts on transferred interests
Spousal Lifetime Access Trust (SLAT) — uses both spouses’ exemptions while retaining indirect access

How to Use This Estate Tax Calculator

$15,000,000 is the single most important number in estate tax planning — and this calculator shows exactly how it applies to your situation. Start by entering the total gross estate value, including real estate, investments, business interests, life insurance, and retirement accounts.

Next, input deductions: outstanding debts and mortgages, estimated funeral expenses, charitable bequests, and any amounts left to a surviving spouse. The calculator applies the unlimited marital deduction automatically for spouse bequests. Select your filing status to determine whether the individual ($15M) or married with portability ($30M) exemption applies.

The results show the taxable estate, the amount over the exemption, the federal estate tax at 40%, the effective tax rate, and the net amount passed to heirs. Run multiple scenarios — for instance, compare the tax impact of a $2 million charitable bequest versus leaving the full estate to heirs. Use a retirement calculator to plan how estate distributions align with beneficiaries’ financial needs.
