Deductions Allowed Against the Taxable Estate

The federal estate tax is not levied on your entire gross estate—dozens of debts, costs, and transfers reduce it to the taxable estate, and understanding which deductions apply can save hundreds of thousands.

Gross estate vs. taxable estate

Your gross estate includes everything—all property, accounts, retirement benefits, life insurance, jointly held assets, and property over which you had control. For a wealthy person, this can be $5 million, $20 million, or much more.

But the IRS does not tax the gross estate. It taxes the taxable estate, which is the gross estate minus all allowable deductions. Deductions are the tool that reduce your tax bill—sometimes to zero, if they’re large enough.

Funeral and administration expenses

When you die, your estate must pay a funeral home, cremate or bury you, and hire lawyers and accountants to settle your affairs. These are the first deductions.

Funeral costs (cemetery plot, flowers, headstone, funeral home fees, obituary notices) are deductible if they are reasonable in amount and paid from estate assets. A $50,000 funeral is hard to justify as “reasonable,” but $5,000–$10,000 typically passes scrutiny.

Administration and probate costs (attorney fees, executor/administrator fees, accounting fees, appraiser fees, court costs) are all deductible. A large estate may incur $50,000–$100,000 in these costs. Small estates incur less; very small probates may escape probate altogether through summary procedures.

These deductions are claimed on the federal estate tax return (Form 706), along with copies of invoices and receipts. They are taken at their actual, paid amount.

Debts and mortgages

Any debt you owed at death reduces the gross estate.

Mortgages on real property are fully deductible. If you owned a $1 million house with a $400,000 mortgage, your gross estate includes the $1 million property value, but the deduction reduces the taxable estate by $400,000.

Personal loans, credit card balances, and notes payable are all deductible if they were genuine debts (not sham transactions intended solely to reduce estate tax). The estate must pay them from its assets; the deduction is taken when the debt is paid.

Income taxes owed by the decedent (an April filing for the year of death, or years prior) are deductible against the estate.

Property taxes, state income taxes, and state inheritance taxes are all deductible.

Note: life insurance proceeds payable to the estate are included in the gross estate, but life insurance payable directly to a named beneficiary (outside the estate) are not—so there is no matching deduction.

The marital deduction

One of the largest and most important deductions is the unlimited marital deduction: you can leave an unlimited amount of property to your surviving spouse and pay zero federal estate tax.

This deduction requires proper structure. If you simply leave property to your spouse in their name, the deduction applies automatically. But for larger estates, planners often use a bypass trust (also called a credit shelter trust or family trust) to preserve the first spouse’s exemption, and a marital trust (such as a QDOT or QTIP) to qualify the rest for the marital deduction.

A QTIP trust (qualified terminable interest property) is common: income goes to the surviving spouse for life, principal goes to the children at the spouse’s death. The full value qualifies for the marital deduction in the first spouse’s estate, deferring tax until the second spouse dies.

The marital deduction is available only if the surviving spouse is a U.S. citizen. If not, a Qualified Domestic Trust (QDOT) must be used, and the deduction is limited.

Charitable deductions

If you leave property to a qualified charity, the full value is deductible. Unlike the marital deduction, there is no limit—you can leave 100% of your estate to charity and owe zero federal estate tax.

Charitable deductions are commonly used in large estates. A $10 million estate might leave $3 million to charity, reducing the taxable estate to $7 million and sheltering $3 million worth of tax.

Deductible recipients must be qualified organizations: the IRS, state and local governments, nonprofit hospitals, schools, churches, and recognized charitable organizations. Private foundations qualify, as do donor-advised funds.

A gift to an individual, even one with charitable intent, is not deductible. You cannot deduct a bequest to a family member, no matter how philanthropic they are.

State and federal taxes incurred by the estate

Any estate or inheritance tax owed to a state, or federal estate tax itself, is deductible against the gross estate. This is rare now (most states have abolished inheritance tax, and federal estate tax applies only to estates above the exemption), but when it applies, the deduction is taken.

Similarly, income taxes owed by the decedent for the year of death or prior years are deductible.

Medical expenses and casualty losses

Final medical and hospital expenses incurred before death are deductible only if they are claimed as an income tax deduction (on the decedent’s final Form 1040) and the estate does not also claim them on Form 706. Most estates claim them on Form 706 because the estate tax savings are larger.

Casualty losses to estate property (theft, fire, flood) during the probate period are deductible if the loss is not covered by insurance and is properly documented. This is uncommon and must be approved by the probate court.

Claims against the estate

Any court-approved claim against the estate—a medical bill, a suit judgment, or a debt the estate acknowledges—is deductible when paid.

The executor or administrator has a window (typically 6 months to 1 year, depending on state law) to publish notice to creditors. Creditors must file claims within that period or lose their right to collect from the estate. All valid, timely claims are deductible.

Planning with deductions

Smart estate planning uses deductions to minimize taxable estate:

1. Use the marital deduction efficiently: structure trusts to defer tax to the surviving spouse’s death, allowing the first spouse’s exemption to apply.
2. Charitable giving: large charitable gifts in a will or trust can eliminate tax on substantial estate portions.
3. Document debts: if you owe money to a family business or individual, formalize it with a promissory note. The estate deduction is larger and cleaner.
4. Discounted valuations: some gifts to family or partnership interests qualify for valuation discounts (25-40%), reducing the taxable estate even before deductions.
5. Timing of funeral and administration costs: pay them promptly from estate assets to ensure they are clearly deductible.

Limitations and pitfalls

Not all reductions in estate value count as deductions:

• Lack of marketability discount: if your estate holds a private business, the value may be discounted because it cannot be quickly sold. This is a valuation reduction, not a deduction, but it has similar effect.
• Non-deductible bequests: leaving money to your children or grandchildren does not reduce the taxable estate (though it does use your lifetime exemption).
• Community property: in community property states, only 50% of marital property is in your gross estate, not a deduction—but the effect is similar.
