Iowa Enacts 6% Severance Tax on Oil and Gas Production

DES MOINES, Iowa — Governor Kim Reynolds signed into law on June 1 a bill that establishes a new severance tax on oil and gas production in the state. The legislation, known as S.F. 2490, imposes a 6% tax on the fair market value of oil and gas at the point of extraction, creating a new tax framework for an industry that is just beginning to explore its potential in Iowa.

The law is seen as a proactive measure to regulate and tax the potential extraction of geological hydrogen. According to a report from the Iowa Capital Dispatch, companies like Koloma have initiated exploratory efforts to determine the viability of extracting hydrogen from rock formations within the state. The legislation aims to establish a clear regulatory and tax structure before any large-scale production begins.

Under the new law, the tax is calculated based on the fair market value of the oil and gas at the wellhead. The revenue generated from this tax will be distributed across several state and local funds. According to an analysis by the Legislative Services Agency, the largest portion, 70.1%, will be directed to the state’s Taxpayer Relief Fund, which currently holds a balance of approximately $4 billion.

The remaining revenue is allocated to specific initiatives. The state’s Environment First Fund is set to receive 10% of the proceeds, earmarked specifically for the Water Quality Initiative. Another 9.9% will be distributed to Iowa's counties in proportion to their share of the state's population. The county where the resource extraction occurs will receive 5% of the tax revenue generated within its borders, and the final 5% will go to the state’s Road Use Tax Fund.

Beyond the tax itself, S.F. 2490 provides a broader regulatory framework for the industry. The bill grants the Iowa Department of Natural Resources authority over production, establishes filing requirements for producers, and outlines rules for handling confidential information. It also introduces provisions for civil penalties for non-compliance.

One of the key regulatory components of the bill addresses landowner rights through a process known as “pooling.” This provision allows for the extraction of resources from a site even if not all landowners have entered into an agreement with the drilling company. A pooling order can be issued by the director of the Department of Natural Resources if at least 25% of landowners on a site have consented to drilling. This threshold is reportedly higher than what is required for other types of mineral extraction in the state, offering a layer of protection for property owners.

The introduction of a new severance tax comes at a time of significant change for Iowa's overall tax system. In recent years, the state has embarked on a major tax reform initiative aimed at simplifying its tax code and lowering rates. According to the Tax Foundation, Governor Reynolds signed legislation in 2022 to transition the state from a nine-bracket individual income tax system with a top rate of 8.98% to a single flat tax of 3.9%. That reform also included eliminating state taxes on retirement income.

As part of these broader reforms, Iowa is also phasing out the deductibility of federal income taxes for both individuals and corporations, a move intended to broaden the tax base as rates are lowered. The new severance tax on a nascent industry represents a targeted approach to revenue generation that contrasts with the state's broader strategy of reducing general income tax burdens.

For business owners in or adjacent to the energy sector, this new Iowa law is a classic example of shifting state tax policy. While the state has been making headlines for broad income tax cuts, it is simultaneously creating a highly specific, and not insignificant, tax burden for a new industry. In our experience, this is a common pattern: states will lower general business taxes to attract investment but then implement targeted excise or severance taxes to capture revenue from successful sectors. This creates a complex compliance landscape. It's not just about paying the 6% tax; it's about understanding the valuation methods, the filing requirements, and the associated regulatory rules under the Department of Natural Resources. Proactive planning is essential. For companies navigating these evolving state-specific obligations, specialized tax preparation and compliance support is critical.

With the law now in effect, industry stakeholders and state officials will be closely watching the progress of geological hydrogen exploration. The effectiveness of the new regulatory framework and the amount of revenue the severance tax ultimately generates will depend on whether these exploratory efforts lead to commercially viable production in the coming years.
