Washington D.C. Estate Tax 2026: The $4.99M Exemption, Graduated Rates, and the Federal Gap

D.C. estate tax rate schedule (2026)

D.C.'s graduated rates apply progressively to the taxable estate above the $4,988,400 exemption. Only the amount within each bracket is taxed at that bracket's rate. The first bracket is narrow — just $11,600 wide — so most taxable D.C. estates move quickly into the 12% second bracket.

The federal–D.C. gap: who gets hit

The central problem for D.C. estates is the more than $10 million gap between D.C.'s $4.988M threshold and the federal $15M threshold. An estate in this band owes D.C. estate tax — potentially hundreds of thousands of dollars — while owing nothing federally. There is no federal deduction for state estate taxes paid (the federal deduction for state death taxes was repealed by EGTRRA 2001 and never restored).

Who commonly falls into this gap in D.C.:

• Long-term D.C. homeowners. A Capitol Hill rowhouse, Georgetown townhouse, or Cleveland Park single-family home that cost $200,000 in 1985 might be worth $2M–$3M today. A professional who also accumulated a Federal TSP ($500K–$1M), a Roth or traditional IRA ($500K), and taxable investments can easily reach $5M–$8M in total estate value — all exposed to D.C. estate tax with no federal exposure.
• Federal employees and SES retirees. D.C. has a high concentration of federal workers. For estate tax purposes, the present value of a FERS annuity or a Federal Employees' Group Life Insurance (FEGLI) policy included in the estate can push a seemingly modest estate above $5M. Senior Executive Service members, senior attorneys, and career agency heads who spent 30+ years in federal service are particularly at risk.
• K Street professionals and consulting firm partners. Law firms, lobbying shops, and consulting firms on or near Pennsylvania Avenue pay partners at levels that produce large accumulations over a career. A D.C. partner approaching retirement with retirement accounts, deferred compensation, and a D.C. home can easily clear $6M–$10M — deep in the D.C.-only estate tax zone.
• Non-resident D.C. property owners. A Virginia or Maryland resident who owns a D.C. condominium, investment property, or commercial interest may owe D.C. estate tax on that D.C.-situs property — even as a non-domiciliary. Virginia itself has no state estate tax; the D.C. property exposure is a surprise to many Northern Virginia residents with D.C. real estate.

No portability: the married couple trap

D.C. does not allow portability of the estate tax exemption between spouses. When the first spouse dies, their $4,988,400 D.C. estate tax exemption is permanently lost unless it was used — through a credit shelter trust or equivalent planning. The federal estate tax allows a surviving spouse to carry forward the deceased spouse's unused federal exemption (by timely filing Form 706), but D.C. does not follow suit.

The practical impact:

A credit shelter trust (also called a bypass trust or AB trust) solves the portability problem by directing assets up to the first spouse's D.C. exemption ($4,988,400) into a trust at death rather than outright to the surviving spouse. The trust corpus is not counted in the survivor's D.C. taxable estate. The surviving spouse can still receive trust income and principal under a HEMS standard — they don't lose access to the money, they lose the D.C. estate tax exposure on the trust assets.

For a D.C. couple with a $10M combined estate: a properly funded credit shelter trust at the first death shelters $4,988,400 in trust. The survivor's estate is approximately $5,011,600 — just barely above the D.C. threshold, resulting in D.C. estate tax of approximately $13,000 versus $681,300 without any planning. The trust doesn't need to be complex to achieve this result, but it does need to be in place before the first death.

Non-residents who own D.C. real property

D.C. estate tax applies to (1) D.C.-domiciled decedents on their worldwide estate, and (2) non-domiciliaries on D.C.-located real and tangible personal property. If you are a Virginia or Maryland resident who owns a D.C. condominium, rental property, or commercial real estate, that D.C.-situs property is subject to D.C. estate tax on a prorated basis.

The practical result: a Maryland resident with a $10M total estate that includes a $2M D.C. property owes D.C. estate tax on the D.C. property's share. The Maryland estate may also owe Maryland estate tax on the full estate (Maryland's exemption is $5M). Executors of multi-state estates should budget for two separate state estate tax filings and coordinate to avoid double-counting deductions.

For a Virginia resident with a $7M estate and a $1.5M D.C. property: Virginia has no state estate tax on the rest of the estate, but D.C. estate tax applies to the D.C. property. The D.C. tax on $1.5M is modest relative to the full estate, but it requires a Form D-76 filing — which many Virginia-based estate attorneys don't encounter routinely.

Planning strategies for D.C. estates

1. Credit shelter trust (most important for married couples)

The single most effective D.C. estate tax planning tool for married couples. A D.C. couple with a $10M combined estate that uses a credit shelter trust at the first death can reduce D.C. estate tax from approximately $681,300 to near zero. Every D.C. couple with a combined estate above $5M — whether from real estate, retirement accounts, investments, or federal pension value — should review this with a D.C. estate planning attorney. The trust must be in place and properly funded before the first death; it cannot be created retroactively after death.

2. Annual exclusion gifting — no clawback

D.C. has no gift tax and no clawback rule on lifetime gifts (unlike New York's 3-year lookback and Vermont's 2-year lookback). Each D.C. resident can give $19,000 per recipient per year (2026 federal annual exclusion) with zero D.C. tax consequence. A D.C. couple gifting to three adult children and three spouses can transfer $228,000/year out of the estate ($19K × 2 donors × 6 recipients) permanently, with no D.C. tax cost. Over 10 years, that's $2.28M removed from the D.C. taxable estate — enough to meaningfully reduce exposure in the $5M–$7M range.

3. Larger lifetime gifts above the annual exclusion

Since D.C. has no gift clawback, large lifetime gifts above the annual exclusion permanently leave the D.C. estate regardless of when made relative to death. A gift of $500,000 to a child (above the $19K annual exclusion) reduces the federal lifetime exemption ($15M) but triggers no D.C. tax at any time. For a D.C. resident whose estate is in the $5M–$15M D.C.-only zone, funding a child's home purchase, education trust, or business removes those assets from D.C. estate tax exposure immediately with no tax cost and no waiting period.

4. Irrevocable Life Insurance Trust (ILIT)

Life insurance owned by an ILIT is not part of the insured's D.C. taxable estate. A D.C. resident with an $8M estate and a $1M life insurance policy who transfers the policy to an ILIT removes $1M from D.C. estate exposure — saving approximately $136,000–$144,000 in D.C. estate tax — while providing beneficiaries with liquidity outside the probate process. FEGLI policies can also be assigned in some circumstances, though the rules are specific.

5. Qualified Personal Residence Trust (QPRT) for D.C. real estate

For owners of high-value D.C. homes (D.C. median home prices rank among the highest in the country), a QPRT transfers the property out of the estate at a discounted actuarial value. The grantor retains use of the home for a term of years; at the end of the term, the home passes to heirs at the original gift-tax value — not the future (higher) value. A D.C. home worth $2.5M today that appreciates to $3.5M in 10 years might be gifted through a QPRT at an actuarial value of $1.1M–$1.5M, saving $160,000–$270,000 in D.C. estate tax on the appreciation that occurs after the gift.

6. Charitable strategies

Assets left to qualified charities are deductible from the D.C. taxable estate. For D.C. residents with charitable intent, a donor-advised fund, charitable remainder trust, or direct bequest to a qualified organization reduces D.C. estate tax dollar-for-dollar at the applicable marginal rate. A $1M charitable bequest by a D.C. resident with an $8M estate saves approximately $136,000–$144,000 in D.C. estate tax at the 13.6%–14.4% marginal rate where that dollar falls.

7. Virginia domicile (for those with flexibility)

Virginia has no state estate tax. A D.C. resident who also maintains a Northern Virginia home or has strong ties to Virginia could consider establishing Virginia domicile to eliminate D.C. estate tax on their worldwide estate. Non-domiciliaries still owe D.C. estate tax on D.C.-situs property, so a Virginia domiciliary who owns a D.C. home would still face D.C. tax on that property — but the rest of the estate escapes D.C. entirely. Domicile change is legally significant: it requires genuine intent and physical presence; D.C. tax authorities scrutinize large estates where the decedent maintained a D.C. residence, a D.C. driver's license, and ongoing D.C. business ties. This strategy is most viable for those genuinely transitioning their primary life to Virginia.

Filing requirements and deadlines

Who must file

A D.C. estate tax return (Form D-76) is required when the decedent's gross estate — or gross estate plus adjusted taxable gifts — exceeds the $4,988,400 exemption. Non-residents must file a D-76 for D.C.-situs property when the D.C. property value exceeds the applicable prorated exemption threshold.

How and when to file

Form D-76 is filed electronically through MyTax.DC.gov (required for deaths in 2017 or later). The filing deadline is 10 months from the date of death. A 6-month extension is available by submitting Form FR-77 before the original deadline. Note: the extension covers the filing deadline only — any tax owed is still due within 10 months to avoid interest.

Penalties and interest

• Late filing: 5% of tax due per month or fraction of a month, up to 25% maximum
• Late payment: 10% annual interest compounded daily on unpaid tax after the original deadline
• D.C. Estate Tax Unit: (202) 478-9146 or through the Office of Tax and Revenue (OTR) at otr.cfo.dc.gov

What heirs need to know when inheriting from a D.C. estate

Who pays the D.C. estate tax?

The personal representative (executor) determines whether the estate exceeds $4,988,400, files Form D-76, and pays any D.C. tax within 10 months of death. As a beneficiary, you don't pay D.C. estate tax directly — it comes out of the estate before distributions reach you. But a D.C. estate tax bill of $250,000–$700,000 can meaningfully reduce the net inheritance, and large estates should ensure the executor has set aside funds for this payment before distributing to beneficiaries.

Step-up in basis still applies

D.C. estate tax is entirely separate from the federal income tax treatment of inherited assets. Heirs still receive a stepped-up cost basis equal to fair market value at date of death, regardless of whether the estate owed D.C. estate tax. A D.C. home with a $200,000 original cost and a $2M date-of-death value gets a basis reset to $2M — the D.C. estate tax doesn't affect this federal income tax benefit.

Timing of distributions

Unlike probate (which can take 12–18 months), D.C. estate tax returns are due within 10 months. Estates that distribute assets before the tax is paid expose the executor to personal liability. Most D.C. estate attorneys recommend withholding a tax reserve from early distributions until the D-76 return is reviewed and accepted by OTR.

D.C. compared to neighboring jurisdictions and other estate-tax states

D.C.'s position is notable compared to its neighbors. Maryland has both a state estate tax ($5M exemption) and a state inheritance tax on non-lineal heirs — making it the only jurisdiction with both taxes. Virginia has neither. For a D.C. resident with the flexibility to genuinely change domicile, the Virginia option (no estate tax) offers the most dramatic potential savings. Maryland offers only marginal improvement (a slightly higher $5M exemption versus D.C.'s $4.988M).

D.C.'s graduated rate structure (11.2% to 16%) is less severe than Washington state's former 35% peak, and similar to New York, Massachusetts, and Illinois at the high end. The absence of a gift lookback period is a significant advantage for lifetime gift planning versus New York or Vermont.

Get matched with a D.C. estate planning specialist

If you're inheriting from a D.C. estate — or planning your own — a fee-only advisor with D.C. estate planning experience can help you understand the Form D-76 filing requirements, the credit shelter trust opportunity, and how D.C.'s rules interact with your full financial picture. The absence of portability in D.C. makes proactive planning especially important for married couples with a combined estate above $5M — every year without a credit shelter trust is a year the first spouse's exemption could be lost.
