Iowa has no estate tax and no inheritance tax for anyone who dies on or after January 1, 2025. The estate tax was eliminated back in 2005, and the inheritance tax was fully repealed after a four-year phase-out that ended at the start of 2025. If you are settling an estate for someone who died in 2025 or later, the only death-related tax to consider is the federal estate tax, which does not apply until an estate exceeds $15 million. The old inheritance tax still matters, though, if the person died before January 1, 2025, or if their Iowa real estate was never cleared of the tax lien.
What Iowa Collects Today
Iowa stopped collecting a state estate tax for deaths on or after January 1, 2005, after federal changes eliminated the state death tax credit that had funded it.1Department of Revenue. Introduction to Iowa Inheritance Tax The inheritance tax, which taxed beneficiaries based on their relationship to the deceased, was the last state-level death tax on the books. Senate File 619, passed in 2021, set a four-year phase-out that cut the rates by 20% each year until the tax disappeared entirely for deaths on or after January 1, 2025.2Iowa Legislature.

As of 2026, Iowa imposes no state death tax of any kind. Property inherited from someone who dies today passes without any Iowa tax and without any state inheritance tax lien attaching to it.
The Federal Estate Tax Boundary
Federal estate tax can still reach large Iowa estates. For deaths in 2026, an estate must exceed $15 million before any federal tax is owed. That threshold was set by the One, Big, Beautiful Bill Act, signed on July 4, 2025, which amended the basic exclusion amount under Section 2010(c)(3) of the Internal Revenue Code.3Internal Revenue Service. What’s New – Estate and Gift Tax Amounts above the exemption are taxed at rates up to 40%.
Married couples can effectively double that protection through portability, which lets a surviving spouse absorb any unused portion of the deceased spouse’s exemption. The election requires filing federal Form 706 for the first spouse’s estate even when no tax is owed, and skipping that filing forfeits the unused exemption permanently.3Internal Revenue Service.

Estates of People Who Died Before January 1, 2025
The repeal only runs forward. If you are administering an estate for someone who died before January 1, 2025, Iowa’s inheritance tax rules still apply in full, including the obligation to file Form IA 706 and pay any tax due.4Iowa Department of Revenue. IA 706 Iowa Inheritance Tax Return Instructions
The return and payment are both due by the last day of the ninth month after the date of death.5Iowa Legislature. Iowa Code 450.94 – Return, Determination, Appeal Late filing carries a 10% penalty on the tax due, and late payment adds another 5%.6Justia Law. Iowa Code 421.27 – Penalties
No inheritance tax is owed if the net estate (gross assets minus debts, funeral expenses, and other liabilities) is less than $25,000.7Cornell Law School. Iowa Admin Code r 701-900.2 – Inheritance Tax Returns and Payment of Tax A return still has to be filed if Iowa real estate is part of the estate, though, because a tax clearance is needed before title can pass cleanly.
Who Owed the Tax
The old inheritance tax was built entirely around the beneficiary’s relationship to the deceased. Surviving spouses, parents, grandparents, children, grandchildren, and stepchildren and their descendants owed nothing regardless of the amount received.8Iowa Legislature. Iowa Code 450.9 – Individual Exemptions Qualified charitable, religious, and educational organizations under IRC Section 170(c) or 2055 were also fully exempt, along with public libraries, hospitals, humane societies, and municipal governments.9Iowa Administrative Code. 701 IAC 86.2 – Inheritance Tax Returns and Payment of Tax
Everyone else fell into one of four schedules with progressively steeper base rates before the phase-out reduction:10Iowa Legislature. Iowa Code 450.10 – Rate of Tax
- Schedule B, for siblings, half-siblings, and children-in-law: 5% up to 10% with no exemption.
- Schedule C, for aunts, uncles, nieces, nephews, cousins, friends, and other individuals: 10% up to 15% with no exemption.
- Schedule D, for-profit entities that didn’t qualify as charitable: a flat 15%.
- Schedule E, for out-of-state charitable organizations: a flat 10%.
The Phase-Out Rates by Year
Senate File 619 cut the rates by a flat 20% each year starting in 2021:2Iowa Legislature. Iowa Tax Rate Changes – Fiscal Topics
- 2021: rates reduced 20% (Schedule C top rate dropped from 15% to 12%).
- 2022: rates reduced 40% (Schedule C top rate to 9%).
- 2023: rates reduced 60% (Schedule C top rate to 6%).
- 2024: rates reduced 80% (Schedule C top rate to 3%).
- January 1, 2025: tax eliminated.
So a sibling who inherited $200,000 in 2024 paid only 20% of what the same inheritance would have cost before the phase-out began.
How the Calculation Worked
For a pre-2025 death, the gross estate of an Iowa resident includes all property owned at death, wherever it sits. For a nonresident, only real estate and tangible personal property physically in Iowa counts.1Department of Revenue. Introduction to Iowa Inheritance Tax Allowable deductions like debts, funeral costs, and administrative expenses come off to produce the net estate.7Cornell Law School. Iowa Admin Code r 701-900.2 – Inheritance Tax Returns and Payment of Tax
Each beneficiary’s share is then identified, and the tax is calculated on that share according to the beneficiary’s relationship to the deceased. The beneficiary, not the estate, is personally responsible for paying the tax on their share.1Department of Revenue. Introduction to Iowa Inheritance Tax Life insurance proceeds paid directly to a named beneficiary and annuities from an employer pension or retirement plan were excluded from the gross estate, though all assets still had to be reported on the return.
The Lien Problem on Iowa Real Estate
This is where the repealed tax still creates real headaches. Iowa’s inheritance tax automatically attached as a lien on every asset in the estate from the moment of death. No recording was required for the lien to be valid, and it took priority over any mortgage or purchase that happened after the death.11Justia Law. Iowa Code 450.7 – Lien of Tax
The lien lasts ten years from the date of death.11Justia Law. Iowa Code 450.7 – Lien of Tax If someone died in 2018 and the estate was never properly closed, the lien on their Iowa real estate won’t expire until 2028. Title companies routinely flag it, and it can hold up a sale or refinance. Clearing the lien means filing the inheritance tax return and either paying any tax owed or showing that none is due. Once the Department of Revenue confirms full payment or no liability, it issues an inheritance tax clearance that releases the property.1Department of Revenue. Introduction to Iowa Inheritance Tax
For deferred estates involving remainder or future interests, a beneficiary can pay the tax early based on the present value of the interest to remove the lien before the interest vests.12Justia Law. Iowa Code 450.52 – Deferred Estates, Removal of Lien For deaths on or after January 1, 2025, no lien attaches at all, so Iowa property inherited from a 2025 or later death is free of this problem from the start.
