Delaware Estate & Inheritance Tax — Best Proven Guide (2026)

✓ Verified June 2026

This guide explains Delaware estate tax and inheritance tax in plain English — whether Delaware taxes your estate, who pays, the exact exemptions, and how the federal estate tax fits in for 2026. All figures verified as of June 2026.

Delaware Estate & Inheritance Tax at a Glance

Here is exactly how Delaware estate tax and inheritance tax work:

Spousal portability (federal): Yes. A surviving spouse may elect portability of the deceased spouse’s unused federal estate tax exemption (called the DSUE amount) by filing a timely federal estate tax return (IRS Form 706), even if no tax is owed. This effectively allows a married couple to shelter up to 30000000 from federal estate tax without a bypass trust.

Gift tax: Delaware does not impose a state gift tax. The federal annual gift tax exclusion is 19000 per recipient for 2026, and the federal lifetime gift tax exemption is unified with the 15000000 estate tax exemption.

Estate Tax vs Inheritance Tax: The Difference

People use these two terms as if they mean the same thing, but they are different taxes that work in opposite ways. An estate tax is charged to the estate itself before anything is handed out — the estate pays it, then the heirs receive what is left.

An inheritance tax is charged to the people who receive the money — each heir may owe tax on their share, and the rate often depends on how closely related they were to the person who died.

This matters for Delaware families because the two taxes are set by different rules. The federal government only has an estate tax, never an inheritance tax. A state can have an estate tax, an inheritance tax, both, or — as in most states — neither. When you know which one (if any) applies in Delaware, you know exactly who would be responsible for paying.

How the Federal Estate Tax Works

No matter which state you live in, the federal estate tax sets a very high exemption, which is the amount an estate can be worth before any federal tax is owed. Estates below that exemption owe no federal estate tax at all, and the overwhelming majority of estates fall well below it.

For 2026, the federal exemption is $15 million per person — a level the One Big Beautiful Bill Act made permanent in 2025 and indexes for inflation — so the figure in the table above is current and is not scheduled to drop.

Married couples get an extra advantage. Anything left to a surviving spouse passes free of federal estate tax under the unlimited marital deduction, and a surviving spouse can often carry over the unused portion of their late spouse’s exemption — a feature called portability. In practice this means a married couple can shield roughly double the individual exemption before federal estate tax ever enters the picture.

Who Actually Owes Estate Tax in Delaware

Delaware imposes neither an estate tax nor an inheritance tax, so most Delaware families will owe no state-level death tax. At the federal level, only estates exceeding the 15000000 per-person exemption (30000000 for married couples using portability) are subject to the 40 percent federal estate tax.

Families with estates approaching or exceeding these thresholds, or with complex assets such as business interests or real estate in multiple states, may benefit from consulting a licensed estate planning attorney or tax advisor.

Other Delaware estate/inheritance tax rules: Delaware repealed its estate tax effective January 1, 2018, under House Bill 16 signed by Governor John Carney on July 2, 2017. The former estate tax (Title 30, Chapter 15 of the Delaware Code) applied to estates exceeding 5490000 with rates from 0.8 to 16 percent. That chapter is now marked as Repealed in the Delaware Code.

Estates of decedents who died on or before December 31, 2017 may still have been subject to the old Delaware estate tax. Delaware does not impose an inheritance tax and has never had one. Delaware also does not have a separate state gift tax.

What This Means for Your Delaware Family

The bottom line for Delaware: because Delaware has neither a state estate tax nor a state inheritance tax, almost every family here will owe no death tax of any kind at the state level. The only tax that could apply is the federal estate tax, and that affects only the largest estates — those above the federal exemption shown above.

For the vast majority of Delaware families, the answer to “will we owe estate tax?” is simply no.

Either way, planning ahead helps. Keeping beneficiary designations current, holding property in the right way, and — for larger estates — talking to a tax professional can keep more of what you have built in your family’s hands. None of this requires owing estate tax; it is simply good estate planning.

It also helps to know what an estate tax does not touch. Life insurance paid to a named beneficiary, retirement accounts with named beneficiaries, and assets held in certain trusts generally pass outside the taxable estate, which is one reason these tools are so common in planning.

Day-to-day inheritances that most Delaware families receive — a home, a bank account, a car, personal belongings — are almost never large enough to trigger any estate tax at all. If you are unsure where your family stands, the safest step is a short conversation with a licensed Delaware estate or tax professional who can look at the actual numbers.

Understanding Delaware Estate and Inheritance Tax

Worrying about Delaware estate tax is common, but most families owe nothing. Whether Delaware estate tax applies depends on the size of the estate and whether Delaware levies an estate tax, an inheritance tax, or neither. The table above shows the exact exemptions and rates, plus the current federal exemption, so you can see where you actually stand on Delaware estate tax.

If your estate is large enough that Delaware estate tax could apply, a licensed tax professional in your state can help you plan.
