Iowa finished phasing out its inheritance tax on January 1, 2025, and the multi-year schedule before that created years of confusion for families and REALTORS® trying to understand what's actually owed when an Iowa estate is settled. Here's the current state of Iowa inheritance tax in 2026, who still pays it, and how it affects probate real estate.

Iowa passed legislation in 2021 that phased out its inheritance tax over a multi-year schedule, and the phase-out is complete: for deaths on or after January 1, 2025, the tax is fully repealed for all recipients. This is different from federal estate tax (which still applies to very large estates) and different from income tax on inherited assets (which may still apply depending on the asset type).
Before the phase-out, Iowa inheritance tax was based on:
1. Who inherited (the relationship between the recipient and the decedent) 2. How much they inherited (the value of the share) 3. What type of asset it was
Iowa had several "classes" of recipients with different tax rates:
For deaths on or after January 1, 2025, Iowa's inheritance tax is fully repealed — every Iowa estate is inheritance-tax-free at the state level. Deaths before 2025 fall under the old phase-out schedule.
However, a few edge cases still exist:
1. Estates of decedents who died BEFORE the phase-out was complete. These are still taxed under the old rules. If you're settling an estate for someone who died in 2021-2024, check the tax year rules.
2. Federal estate tax. Iowa's phase-out doesn't affect federal estate tax. Federal estate tax only applies to estates over approximately $15 million per person (2026 threshold, adjusted annually). Very few Iowa estates hit this.
3. Income tax on inherited IRAs. Inherited traditional IRAs and 401(k)s still generate income tax when the beneficiary withdraws. This is not an "inheritance tax" but it's what most families actually pay after an estate settles.
4. Capital gains on inherited property. Inherited real estate gets a stepped-up basis (the cost basis resets to fair market value at the date of death), which usually means heirs owe zero capital gains if they sell soon after inheriting. Holding it and watching it appreciate can create future capital gains exposure.
For most Iowa families, the most important tax rule isn't the inheritance tax phase-out — it's the federal stepped-up basis rule.
Here's how it works: If your parent bought a Des Moines house in 1982 for $45,000, and it's worth $285,000 when they die, the house's cost basis for your tax purposes is $285,000 (the market value at death), not $45,000 (the original purchase price).
If you sell the house soon after inheriting for $290,000, your taxable gain is only $5,000 — not the $245,000 that would apply if you'd simply been given the house while your parent was alive. This is a massive tax advantage and one of the reasons most estate planners recommend holding appreciated assets until death rather than gifting them.
The stepped-up basis means that for most Iowa inherited homes:
1. No Iowa inheritance tax is owed on any death since January 1, 2025 2. Minimal or no capital gains if sold within a reasonable period after death 3. The home can be sold quickly without tax drag 4. Heirs generally get clean cash after closing costs and any estate debts
The main remaining tax considerations are:
1. Get professional valuations at date of death. This establishes the stepped-up basis for every inherited asset — critical for future tax reporting. For real estate, hire an appraiser or have a REALTOR® run a defensible comparative market analysis dated to the date of death.
2. File the decedent's final returns. Federal Form 1040 and Iowa IA 1040 for the year of death.
3. File Form 1041 if needed. If the estate earns over $600 in income during probate (from interest, rent, etc.), it needs its own tax return.
4. Coordinate with a CPA and probate attorney. Tax details on Iowa estates are technical enough that DIY often costs more in mistakes than professional fees would have.
Q: Does Iowa still have an inheritance tax in 2026? A: Iowa's inheritance tax is fully repealed for deaths on or after January 1, 2025 — no Iowa inheritance tax applies, regardless of who inherits. Estates of decedents who died before 2025 may still owe tax under the older phase-out rules.
Q: Do I owe taxes when I inherit a house in Iowa? A: Usually no. Iowa's inheritance tax was repealed effective January 1, 2025, so no Iowa inheritance tax applies to any death since — regardless of who inherits. At the federal level, inherited property benefits from the stepped-up basis rule, which resets the cost basis to market value at the date of death — meaning minimal or no capital gains if you sell soon after inheriting.
Q: What is the stepped-up basis for inherited property? A: The stepped-up basis is a federal tax rule that resets the cost basis of inherited property to its fair market value on the date of the decedent's death. This eliminates most of the built-in capital gains tax that would otherwise apply and is the single biggest tax advantage of inheriting appreciated assets.
Q: Do I need to file a tax return for an inherited Iowa house? A: The decedent's final income tax return (Form 1040 federal and IA 1040 state) must be filed for the year of death. If you sell the house shortly after inheriting, you report the sale on your own tax return but usually owe minimal or no capital gains due to the stepped-up basis. If the estate generates over $600 in income during probate, it files its own Form 1041.
