Program description
The Historic Preservation Tax Credit program provides State tax credits to developers who sensitively rehabilitate historic buildings to offer them new life. Iowa offers this tax credit program to ensure character-defining features and spaces of buildings are retained to help create distinct and vibrant communities. Approved projects may receive a state income tax credit of up to 25% of the project’s qualified rehabilitation expenses (QREs). QREs are defined as expenses allowed under Section 47 of the federal Internal Revenue Code . Generally, QREs include project expenditures related to structural components of the building and some soft costs charged to a capital account. Tax credits may be carried forward for 5 years, or until depleted. Tax credits are transferable and refundable. For FY 2027, the Historic Preservation Tax Credit program has $45 million allocation. Eligibility The process for applying for Historic Preservation Tax Credits is a 3-part application process. Applicants MUST have Part 1 AND Part 2 applications approved by the State Historic Preservation Office prior to applying for tax credits through Iowagrants.gov. More information on the 3-part process can be found on IEDA’s Historic Preservation Tax Credit page under “How Do I Apply?” Only an eligible taxpayer may apply for tax credits under this program. An eligible taxpayer is defined as the fee simple owner of the property or someone having a long-term lease, which meets the requirements of the federal historic rehabilitation credit. Units of government (cities/ counties) are not eligible to apply for credits. Project buildings must be historically significant for the project to qualify for tax credits. Buildings must meet at least one of the following criteria: Building is listed on the National Register of Historic Places or determined by the staff at the State Historic Preservation Office (SHPO) to be eligible for listing Building is contributing to the significance of a historic district that is listed on or eligible to be listed on the National Register of Historic Places Building is designated as a local landmark by city or county ordinance Barn constructed before 1937 OR a barn that is listed on or eligible for listing on the National Register of Historic Places Projects must include substantial rehabilitation. Substantial rehabilitation is defined as follows: Commercial buildings: QREs must equal at least 50% value of the building (excluding land) before rehabilitation or $50,000, whichever is less Non-commercial buildings: QREs must equal at least 25% of the assessed value of the building (excluding land) before rehabilitation or $25,000, whichever is less Rehabilitation work must meet federal Secretary of the Interior’s Standards for Rehabilitation. Ineligible Costs QREs do not include project expenditures financed by federal, state or local grants or forgivable loans, unless allowed under Section 47 of the Internal Revenue Code. “Government funding” or “funding originating from a government” includes but is not limited to: (1) Any funding the applicant received from a government; or (2) Funding from a third party or a series of third parties where those funds originally came from a government or were derived from a government payment, grant, loan, tax credit, rebate, or other government incentive; or (3) Funding from a third party or a series of third parties where those funds are derived from, secured by, or otherwise received in anticipation of a government payment, grant, loan, tax credit, rebate, or other government incentive. In some instances, government funding may be eligible to be included in QREs, depending on how the government funding is treated for tax purposes (i.e. If the funding is treated as taxable income). Applicants should consult with their tax advisor regarding questions on the eligibility of funds. As part of the application, applicants must submit a memo for all public funding sources/government funding deemed eligible. Memos should include an itemized list of eligible public financing sources and reasoning of eligibility for each. Failure to produce supporting documentation will disallow sources/costs paid and reduce the amount of credits available to the project.

💡 Tips for applicants
- Complete the 3-part application process with SHPO (State Historic Preservation Office) before submitting to Iowagrants.gov. Parts 1 and 2 must be approved first.
- Document all qualified rehabilitation expenses carefully. QREs follow federal Section 47 IRC definitions and include structural components and capital-account soft costs.
- If using any government funding, consult a tax advisor immediately. Government-funded expenses may be excluded from your QRE calculation.
- Plan your project timeline around the 5-year tax credit carryforward period. Credits are valuable because they're transferable and refundable.
- Ensure your rehabilitation work strictly follows the Secretary of the Interior's Standards. Non-compliance will disqualify the project.
⚠️ Common mistakes
Applications fail when SHPO approval (Parts 1 & 2) isn't complete before applying for tax credits. Including government-funded expenses in QREs without proper tax treatment documentation. Underestimating substantial rehabilitation thresholds (50% for commercial, 25% for non-commercial).
