Iowa does not impose a separate state estate tax due to changes in the federal estate tax laws that phased out the state pick up tax effective for deaths occurring on or after January 1, 2005. However, Iowa is among one of seven states that assess a separate state inheritance tax on certain property owned by an Iowa resident and real estate and tangible personal property located in Iowa that is owned by a nonresident.

The Difference Between Estate Taxes and Inheritance Taxes

While it may just seem to be semantics, there is a real difference between an estate tax and an inheritance tax:

  1. An estate tax is charged against the entire estate regardless of who the beneficiaries of the estate may be.
  • An inheritance tax is only charged against the shares of certain beneficiaries of an estate.

​The Beneficiaries That Are Subject to the Iowa Inheritance Tax

Each beneficiary of an Iowa estate receives or does not receive, an exemption from the Iowa inheritance tax based on the beneficiary's degree of relationship to the decedent. Here are the categories of beneficiaries and their applicable exemptions, or lack thereof, that are available under Iowa law:

  • For deaths occurring on or after July 1, 1997, surviving spouses; parents, grandparents, great-grandparents, and other lineal ascendants; and children (biological and legally-adopted), stepchildren, grandchildren, great-grandchildren, and other lineal descendants are entirely exempt from the Iowa inheritance tax.
  • Charitable, religious, educational, and veterans organizations as defined in sections 170(c) and 2055 of the Internal Revenue Code; public libraries; public art galleries; hospitals; humane societies; municipal corporations; bequests for care of cemetery lots within the state of Iowa, and bequests for religious services not in excess of $500.00 are entirely exempt from the Iowa inheritance tax.
  • Any other beneficiary not listed above, including siblings, nieces, nephews, cousins, and friends, are taxed on the entire share passing from the estate to that person.

The Life Insurance Included in an Iowa Estate

Life insurance that is payable to the decedent's estate is included in the value of the estate, while life insurance that is payable to a living beneficiary is not.

What Expenses Can Be Deducted From the Value of an Iowa Estate

Certain expenses can be deducted from the value of an Iowa estate, including:

The Iowa Inheritance Tax Rates

The Iowa inheritance tax rates are as follows:

  • If the net estate of the decedent is valued at less than $25,000, then there is no Iowa inheritance tax due.
  • Schedule B beneficiaries: For brothers, sisters (including half-brothers, half-sisters), sons-in-law, and daughters-in-law, there is no exemption, and the inheritance tax rates range from 5% to 10%.
  • Schedule C beneficiaries: For uncles, aunts, nieces, nephews, foster children, cousins, brothers-in-law, sisters-in-law, step-grandchildren, and all other individual persons, there is no exemption, and the inheritance tax rates range from 10% to 15%.
  • Schedule D beneficiaries: For firms, corporations, and societies organized for profit (including organizations failing to qualify as charitable, educational, or religious organizations, to include social and fraternal organizations that do not qualify under IRC 170(c) and 2055), the tax rate is 15%.
  • Schedule E beneficiaries: For charitable, educational, and religious organizations organized under the law of a foreign country, and bequests for religious services in excess of $500.00, the tax rate is 10%.
  • Schedule F beneficiaries: For unknown heirs, as distinguished from beneficiaries who are not presently ascertainable, due to contingent events, the tax rate is 5%.
