Oregon estate tax
Oregon is one of 13 jurisdictions with its own estate tax. For deaths in 2026, it applies to estates worth more than $1,000,000, at rates of 10% to 16%. The tax is paid by the estate, not by the heirs.
The estate generally includes everything the person owned at death: the home, bank and brokerage accounts, retirement accounts, business interests, and life insurance they owned. Debts, funeral and administration costs, and gifts to a spouse or charity reduce the taxable amount. Nonresidents who owned real estate in Oregon can also owe Oregon tax on that property.
Because the Oregon threshold is well below the federal $15 million, many estates owe Oregon tax while owing no federal estate tax at all.
What's specific to Oregon
- Oregon's $1 million exemption is the lowest in the country and is not indexed for inflation.
- Rates start at 10% on the first $500,000 over $1 million; a $2 million estate owes roughly $100,000.
- The return is due 12 months after death. An extension to file (OR-706-EXT) does not extend the time to pay.
What executors file, and when
- Oregon estate tax return (OR-706): due 12 months after the date of death, if the estate is over $1,000,000. File with the Oregon Department of Revenue.
- Federal Form 706: only if the estate is over $15 million, or to elect portability for a surviving spouse. Due 9 months after the date of death (an automatic 6-month extension to file is available on Form 4768).
- Final Form 1040 for the person who died: due April 15 of the following year.
- Form 1041 (estate income tax): if the estate has $600 or more of income.

Federal estate tax
For deaths in 2026, the federal estate tax applies only to estates over $15,000,000 per person, at rates up to 40%. The exemption was set by the July 4, 2025 tax law (Public Law 119-21, often called the "One Big Beautiful Bill Act"; the IRS now calls it the Working Families Tax Cuts law), is permanent, and is indexed for inflation starting in 2027. A surviving spouse can add the unused exemption of the first spouse to die (portability) by filing Form 706. See the federal estate tax guide.
Frequently asked questions
Do I have to pay inheritance tax in Oregon?
No. Oregon has no inheritance tax, so heirs do not pay state tax on what they receive from a Oregon resident. If the person who died lived in Pennsylvania, New Jersey, Kentucky, Maryland or Nebraska, or owned real estate there, that state's inheritance tax can apply even if you live in Oregon.
Does Oregon have an estate tax in 2026?
Yes. Oregon taxes estates over $1,000,000 for deaths in 2026, at rates of 10% to 16%. The executor files the return and pays the tax from the estate before assets are distributed.
Who must file a Oregon estate tax return, and when is it due?
The executor files if the estate exceeds the Oregon filing threshold ($1,000,000 for 2026 deaths). It is due 12 months after the date of death on Form OR-706. Nonresidents who owned real estate or tangible property in Oregon may also have to file.
Can an estate owe Oregon estate tax but no federal estate tax?
Yes, and that is common. Oregon's threshold ($1,000,000) is far below the federal exemption of $15 million, so many estates owe state tax while owing nothing federally.
Is an inheritance taxable income?
No. Money or property you inherit is not federal taxable income. But withdrawals from an inherited traditional IRA or 401(k) are taxed as income, and if you sell inherited property you may owe capital gains tax on any increase in value after the date of death.
What is the federal estate tax exemption for 2026?
$15,000,000 per person for deaths in 2026, set by Public Law 119-21 (2025). It is permanent and indexed for inflation from 2027. A surviving spouse can add the unused exemption of the first spouse to die (portability) by filing Form 706.
