Iowa homeowners have a new homestead tax exemption, and the homestead credit most Central Iowa owners filed for is gone. Division 20 of 2026 Iowa Acts, Senate File 2472, signed by the Governor on May 18, 2026, replaced the homestead tax credit with a homestead tax exemption worth 10% of the taxable value of the homestead. The Iowa Department of Revenue puts the practical result plainly: the tax benefit to a homeowner is greater under the new law than it was under the credit. Here is what changed, who has to do anything about it, and when it reaches your tax bill.
The distinction sounds like paperwork, and it is the whole reason the new benefit is larger. The Iowa Department of Revenue defines the difference this way: an exemption is a reduction in the value of the property that a taxpayer pays taxes on, while a credit is a direct reduction of the tax amount.
The old homestead credit was equal to the property taxes paid on $4,850 of a homestead's value. That number had not moved in decades while Central Iowa values climbed, so the benefit shrank in real terms every year. The new exemption is a percentage of your own taxable value, so it scales with your home instead of sitting still.
The exemption equals 10% of the taxable value of your homestead, with a floor and a ceiling set in statute:
Two points matter for reading your own numbers. First, these are amounts of value, not dollars off your bill. The exemption removes that much taxable value before the levy rate is applied, so your actual savings depend on the consolidated levy for your parcel, which your county treasurer publishes address by address. Second, the floor does real work in Central Iowa: a homestead with a taxable value under $55,000 still receives the full $5,500, and 10% of a typical metro home lands between the floor and the ceiling rather than at either end.
The Department's June 23, 2026 guidance to assessors adds the sequencing. The 10% exemption is applied after assessment limitations, the rollback, but before the exemption for owners 65 and older and before the military service exemption. For both homestead exemptions, a homestead means the dwelling and appurtenances plus up to one half acre inside a city plat, or up to 40 acres outside one, under Iowa Code sections 561.1, 561.2 and 561.3.
This is the question I get most, so I will answer it directly. The Iowa Department of Revenue states that claimants currently receiving the homestead tax credit do not need to refile. If your homestead claim was already on file and allowed, and you still live in the home as your primary residence, your county converts you to the new exemption without a new application.
No form, no fee, no deadline to beat. If you see an email or a letter offering to file your Iowa homestead exemption for a fee, you do not need it. The application is a free county form, and most Central Iowa owners reading this are already covered.
New owners are the group that can lose money here. A homestead claim does not follow the house. It follows the owner, so buying a home from someone who had the benefit does not give it to you.
File the Homestead Tax Exemption application, Iowa form 54-028, with your city or county assessor on or before July 1 of the year you first claim it. A claim filed after July 1 is treated as a claim for the following year, which means a full year of waiting for a benefit you qualified for the day you closed. Once a claim is filed and allowed, it carries forward for successive years with no further filing as long as you still qualify.
Polk, Story, Dallas and Warren counties all take the form through their assessor's office, and several accept it online. If you closed in 2026 and have not filed, put it on the calendar now rather than next June.
The exemption for claimants 65 years of age or older is separate and survives the change. Eligible owners continue to receive an additional $6,500 in taxable value exempted, applied after the 10% exemption. The disabled veteran homestead tax credit also remains in place; the Department of Revenue confirms the new law does not eliminate it. For applications submitted on or after July 1, 2026, the homestead definition used for that veteran credit is limited to the dwelling and up to one half acre of land.
Not this year. The change is retroactive to assessment year 2026, and the Department of Revenue states it applies to property taxes paid in September of 2027 and March of 2028.
That lag is normal in Iowa and it catches people off guard constantly. Values are assessed as of January 1, the levy is set the following spring, and you pay in two installments well after that. I walk through the full timing, the rollback and the escrow consequences in Iowa Property Taxes Explained. For the program this exemption replaced, and the history behind it, see my earlier post on the Iowa homestead benefit.
The same law changed how assessment increases are handled, starting with assessment years beginning January 1, 2027. If a residential property's actual value rises 10% or more compared with either of the two preceding assessment years, the assessor must give the taxpayer a written statement explaining the reasons and separating how much of the increase came from revaluation, a classification change, or new construction and improvements.
And in a protest or appeal where residential value rose 10% or more, excluding new construction, improvements, renovation and classification changes, the assessor now carries the burden of proof that the valuation is not excessive or inequitable. Under the prior rule, the owner had to build that case. If you have ever looked at an assessment notice and decided it was not worth the fight, that calculation changed. The bill text is on the Iowa Legislature's site.
If you own a duplex or a single family home with a rented room and you live in it, the homestead exemption applies to your homestead portion, not to the whole parcel automatically. The assessor decides how the property is treated, so ask the question directly rather than assuming. Property tax is also the operating expense most new investors underestimate, especially on new construction where the first bill is land only. Run the fully assessed figure, not the first year figure, through the deal calculator before you decide a property cash flows.
What this means for your strategy: If you already have a homestead claim on file, you are automatically moving to a larger benefit and there is nothing to do. If you bought in Central Iowa this year, file form 54-028 with your county assessor before July 1 or you forfeit a year. Either way, expect the change to appear on the taxes you pay in September 2027, not this fall, and keep using your fully assessed tax estimate when you budget.
