Answer Capsule: How Does Iowa’s 60% Refundability Rate Impact Pre-Revenue Startups?

Pursuant to HF 2317 and SF 657, Iowa is drastically reducing the cash-flow utility of its R&D tax credit, dropping refundability to a mere 60% in 2026 (and 50% in 2027) with no carryforward for the remainder. This subjects pre-profit biotech and tech startups—entities with massive capital burn rates and zero tax liability—to severe liquidity crises. To prevent a mass exodus of talent to states like New York or New Jersey, the Iowa Legislature must establish an Innovation Tier restoring 100% refundability for firms under $5M in revenue, and launch a Tax Credit Transfer Marketplace enabling startups to sell excess credits to profitable domestic corporations.

Key Takeaways

The Erosion of the “Synthetic Grant”: Iowa’s legacy RAC functioned as non-dilutive capital (100% refundable) for startups; the mandatory phase-down permanently severs this critical funding lifeline.
The “Use It or Lose It” Penalty: Unlike states offering multi-decade carryforwards, Iowa forces pre-revenue firms electing refunds to permanently forfeit the unrefunded 40% (soon to be 50%) of their earned credit.
Compliance Math Deficit: Mandatory CPA verification costs (averaging $10,000) combined with a 60% refundability cap mathematically decimate the net benefit for small claims, rendering the program economically unviable for true startups.
Proposed Solution 1 (Innovation Tier): Restrict the massive corporate drain on the $40M pool by carving out a 100% refundability tier exclusively for businesses under 7 years old with <$5M in annual revenue.
Proposed Solution 2 (Transfer Marketplace): Implement a New Jersey-style transfer program allowing startups to sell paper tax credits to profitable Iowa conglomerates for 85-90% cash value, maintaining strict fiscal neutrality for the state.

Introduction

The State of Iowa has arrived at a critical juncture in its economic development trajectory, defined by a fundamental shift in how it incentivizes industrial and technological advancement. For decades, Iowa was positioned as a national leader in fostering innovation through a robust, uncapped, and fully refundable Research Activities Credit (RAC). This framework served as a cornerstone for the state’s burgeoning biotechnology, advanced manufacturing, and software engineering sectors, providing an essential liquidity mechanism for pre-revenue startups and small-to-medium businesses (SMBs).¹ However, the passage of House File 2317 in 2022 and Senate File 657 in 2025 has initiated a comprehensive restructuring of this incentive landscape. Central to this transition is the systematic reduction of the refundability rate for excess credits—scheduled to reach a pivotal 60% threshold in 2026—and the eventual replacement of the legacy entitlement program with a capped, application-based system.¹

This policy shift represents a move toward fiscal restraint and targeted industrial support, yet it simultaneously introduces significant cash-flow constraints for the state’s most innovative early-stage firms. The reduction in refundability, when coupled with the phase-out of supply expenses and the introduction of a statewide $40 million cap, creates an environment where Iowa’s “pre-profit” innovators may find themselves at a competitive disadvantage relative to those in states with more aggressive liquidity support models.³ This report provides an exhaustive analysis of the policy issue, contextualizes the change within the broader Iowa R&D framework, and proposes two practical solutions intended to preserve Iowa’s status as a hub for scientific and technological excellence.

Contextual Framework: The Evolution of Iowa’s Research Incentives

The Iowa Research Activities Credit has historically been one of the state’s most utilized corporate tax expenditures, designed to encourage firms to conduct high-value experimentation within state borders. Historically, the credit was modeled after the federal Research and Experimentation Tax Credit under Section 41 of the Internal Revenue Code (IRC), offering a 6.5% credit on qualified research expenditures (QREs) that exceeded a base amount.¹

The primary mechanism that allowed this credit to support startups was its total refundability. In the traditional Iowa model, if a business generated more tax credits than it had state tax liability—a common scenario for pre-revenue startups—the state would issue the remainder as a cash refund.² This non-dilutive capital often served as a “synthetic grant,” funding the high-skilled payroll and experimental supplies necessary to bridge the gap between initial research and commercialization.¹⁰

The Legislative Pivot: From HF 2317 to SF 657

The transition toward the 2026 refundability threshold began in earnest with the signing of House File 2317 on March 1, 2022. This legislation mandated a five-year phase-down of the refundable portion of the RAC and the supplemental RAC awarded under the High Quality Jobs (HQJ) program.¹ This trajectory is detailed in the table below, illustrating the systematic erosion of cash-flow support for pre-profit firms.

Table 1: Phase-Down of Refundability and Supplies

Tax Year	Refundability Percentage of Excess Credit	Supply Expense Eligibility
2022 and Prior	100%	100%
2023	90%	80%
2024	80%	60%
2025	70%	40%
2026	60%	20%
2027 and Beyond	50%	0%

The policy landscape was further altered by Senate File 657 in June 2025, which effectively repeals the legacy RAC for tax years beginning on or after January 1, 2026.³ In its place, the state has established the new “R&D Tax Credit Program,” managed by the Iowa Economic Development Authority (IEDA). This new program introduces several restrictive layers: a $40 million statewide annual cap, a reduced maximum credit rate of 3.5% of QREs, and a competitive application process that replaces the previous “routine tax form entry” model.³

The Policy Issue: The Impact of 60% Refundability on Cash Flow

As the refundability rate drops to 60% in 2026, the fiscal incentive for pre-revenue startups is halved not only by the rate reduction (from 6.5% to 3.5%) but also by the inability to monetize 40% of the credit earned.¹ This creates an immediate and quantifiable strain on the working capital of companies that are rich in intellectual property but poor in liquid assets.

Liquidity Constraints and the Startup “Valley of Death”

For a pre-revenue biotechnology or advanced manufacturing firm, every dollar of state refund typically represents reinvestment in payroll or specialized laboratory equipment. The reduction to 60% refundability effectively removes 40 cents of liquidity for every dollar of excess credit. Unlike some states that allow businesses to carry forward the non-refundable portion to future tax years, the legacy RAC rules in Iowa do not allow taxpayers to carry forward the unused portion of their refundable credits once the refund election is made.¹ This results in a permanent loss of the incentive’s value for the very companies the state seeks to nurture through their formative years.

Furthermore, the simultaneous phase-out of supply expenses as QREs—dropping to only 20% eligibility in 2026—compounds the problem.¹ For startups in the medical device or sustainable aviation fuel sectors, where physical prototyping and chemical supplies represent a significant portion of R&D costs, the effective value of the credit is diminished further.¹⁰

Compliance and Uncertainty Risks

The 2026 framework introduces a mandatory CPA verification process for all claims submitted to the IEDA.³ While intended to ensure program integrity, this requirement adds an estimated $5,000 to $15,000 in annual compliance costs per company.³ For a small startup expecting a $50,000 refund, a $10,000 compliance cost combined with a 40% reduction in refundability drastically lowers the net benefit of the program.

There is also the issue of pro-rata allocation. Because the total award pool is capped at $40 million—a significant decrease from the $77.6 million claimed in FY 2024—businesses will not know their final credit amount until the IEDA distributes the pool at the end of the year.⁵ This “timing risk” makes it impossible for startups to accurately forecast their cash flow, potentially leading to conservative hiring decisions or the deferral of critical research projects.³

Comparative Policy Landscape: Iowa vs. Peer States

The strategic danger of the 60% refundability rate is best understood when compared to the incentive structures of competing jurisdictions. Iowa’s primary competitors for high-tech talent and investment—both in the Midwest and on the coasts—are maintaining or expanding liquidity mechanisms for small firms.

Table 2: State R&D Liquidity and Refundability Comparison

State	R&D Credit Mechanism	Refundability/Liquidity Policy
Iowa (2026)	3.5% Rate; $40M Cap	60% Refundable; No Carryforward.
Minnesota	10% on first $2M QREs	25% Refundable in 2026; 15-year carryforward.
New York	15-20% Rate for Life Sciences	100% Refundable for certified new firms.
New Jersey	10% Rate; Transferable	Credits/NOLs can be sold for ≥80% cash.
Virginia	15-20% Rate for SMBs	100% Refundable for firms with <$5M QREs.
Texas	8.7% Rate; Permanent	20-year carryforward; Refundable for some entities.

While Iowa’s 60% refundability rate is technically higher than Minnesota’s 25%, Minnesota offers a much higher initial credit rate (10%) and allows for a 15-year carryforward of the non-refundable portion.¹⁷ More importantly, states like New York and Virginia specifically protect their small business sectors by offering 100% refundability to firms below certain revenue or expense thresholds.¹⁹ In this context, Iowa’s blanket reduction for all firms, regardless of size or revenue status, risks signaling a retreat from the “startup-friendly” reputation it has cultivated over the last three decades.⁵

Proposed Solution 1: Implementation of an “Innovation Tier” for Small Businesses

The Iowa Legislature should consider modifying the 2026 R&D Tax Credit Program to include a “Targeted Refundability Tier” for small, pre-revenue, and growth-stage companies. This solution would restore 100% refundability for firms that meet specific criteria designed to identify high-potential innovators that lack the tax liability to utilize non-refundable credits.

Eligibility Criteria and Mechanism

To prevent the “wastage” of state funds on large, established corporations that have historically claimed the lion’s share of the RAC, the 100% refundability tier should be strictly limited.⁹ Eligibility should be based on three primary metrics:

Revenue Cap: The 100% refundability should only apply to businesses with annual gross revenues of less than $5 million. This aligns with federal standards for “Qualified Small Businesses” that are eligible to apply R&D credits against payroll taxes.²²
Operational Maturity: Eligible firms should be less than seven years old, reflecting the typical timeline for deep-tech and bioscience startups to reach profitability.⁵
Iowa Payroll Concentration: To ensure the state’s investment translates into local growth, at least 75% of the firm’s R&D activities and associated payroll must remain within Iowa borders.¹³

Integration with the IEDA Process

Under the current SF 657 framework, businesses must already apply to the IEDA for a tax credit certificate.³ The IEDA could easily integrate the “Innovation Tier” into this process. Businesses would submit their revenue and age verification during the initial application. The IEDA would then issue a specialized “Startup Tax Credit Certificate” that instructs the Department of Revenue to issue the refund at 100% of the approved credit value, while larger, more established firms would receive their certificates at the 60% refundability rate.³

Proposed Solution 2: Establishing a Tax Credit Certificate Transfer Program

A second, more market-oriented solution is the creation of a “Tax Credit Transfer Marketplace,” modeled after the successful program in New Jersey.¹¹ This would allow Iowa startups to “sell” their 2026 R&D tax credits to profitable Iowa corporations in exchange for immediate cash.

The Mechanics of the Transfer

In this model, a pre-revenue SMB that is awarded a $100,000 R&D tax credit certificate under the 2026 program would have two choices:

Direct Refund: Receive a 60% cash refund from the state ($60,000) and lose the remaining $40,000.¹
Market Sale: Sell the full $100,000 tax credit certificate to a profitable Iowa-based insurance company or manufacturer for 85-90% of its face value (e.g., $90,000).¹¹

The startup gains $30,000 more in liquidity than the state would otherwise provide, and the buying corporation receives a $100,000 tax offset for only $90,000, creating a net tax savings that encourages established Iowa industries to support the local startup ecosystem.¹¹

Strategic Benefits of the Marketplace

The transfer program would have several secondary benefits beyond mere cash flow:

Corporate Mentorship: By facilitating transactions between large Iowa firms and early-stage startups, the state encourages strategic partnerships, potentially leading to future acquisitions or joint ventures.²⁶
Credibility Signaling: Receiving an IEDA-approved transferable credit serves as a “stamp of credibility” that helps startups secure follow-on private venture capital.¹¹
Fiscal Neutrality: Since the total amount of credits is already capped at $40 million under SF 657, the state’s total fiscal exposure does not increase. The program merely shifts who ultimately uses the credit to offset their tax liability.³

Implementation and Safeguards: Preventing Fraud and Wastage

Any expansion of tax credit flexibility must be coupled with rigorous administrative safeguards. The shift to an IEDA-managed, application-based program in 2026 already provides the infrastructure necessary to prevent the historical issues of “aggressive claim inflation” and “predatory consulting”.¹⁶

The Role of CPA Verification

The requirement for CPA-verified reports of QREs is a critical deterrent to fraud.³ The state should go further by adopting a “Six-Eye Review” process for all “Innovation Tier” or “Transferable” claims. This would involve:

Technical Review: A qualified engineer or subject matter expert within IEDA verifies that the activities meet the federal “Four-Part Test” for R&D.¹⁶
Financial Audit: A CPA verifies the actual dollars spent on wages and supplies.³
Administrative Compliance: IEDA staff ensures the business meets all residency, industry-sector, and revenue requirements.³

Outcome Reporting and Clawbacks

To ensure that the “Initial Cost Outlay” (in the form of restored refundability) is meeting its public purpose, participating SMBs should be required to file an annual “Economic Impact Report” for five years following the award.³ This report must disclose:

The number of net new high-quality jobs created in Iowa.
The average wages paid for those jobs (relative to the state median).
Follow-on private investment secured as a result of the R&D liquidity.

The IEDA should maintain discretionary authority to impose “clawbacks” or reduce future credit awards for companies that experience mass layoffs or fail to meet their research commitments, a provision already introduced in SF 657.⁴

Cost-Benefit Analysis: The ROI of Refundability

Critics of refundable tax credits often view them as a “giveaway” of current tax revenue.⁹ However, a more nuanced economic analysis reveals that for startups, these expenditures act as high-yield investments that pay for themselves through future tax revenue and the “multiplier effect” of high-skilled job creation.

The Fiscal Multiplier of High-Growth Firms

According to studies by the National Bureau of Economic Research (NBER), state-level R&D credits increase entrepreneurial activity by approximately 7% on average, with a 20% rise in “high-quality” new firm formation over a ten-year horizon.²⁹

Table 3: Economic Impact of Refundability Restoration

Economic Factor	Impact of Restoring 100% Refundability for SMBs
Survival Rate	Firms receiving liquidity support have survival rates 2x higher than industry benchmarks.¹¹
Direct Tax Return	A single biotech startup hiring 20 engineers at $100k/year generates ~$75k in annual state payroll tax.
Future Corporate Tax	High-growth firms often yield significant corporate tax revenue once they reach the commercialization phase.
VC Leverage	Every $1 of state incentive can leverage $5-$10 in private venture capital investment.¹¹

Modeling the Initial Outlay

If the state were to restore 100% refundability for the “Innovation Tier” (firms with <$5M revenue), the additional annual cost is estimated to be between $2 million and $4 million—a fraction of the total $40 million R&D cap. This calculation assumes that approximately 10-15% of the total R&D credit pool is awarded to eligible startups.

The “Future Benefit” that pays for this program is found in the avoidance of “startup flight.” If Iowa retains just three high-growth firms that would have otherwise relocated to Minnesota or Texas, the resulting payroll, sales, and eventually corporate tax revenue from those firms will exceed the $4 million outlay within five to seven years.²⁷

Importance of the Policy Change and Risks of Inaction

The decision to proceed with the 60% refundability reduction without providing a safeguard for SMBs carries profound negative consequences for Iowa’s long-term economic health.

The Threat of Regional Uncompetitiveness

Innovation is a competitive market. States like Minnesota are actively bucking national downward trends in venture capital by enhancing their R&D and startup incentives.¹⁷ If Iowa reduces its cash-flow support for pre-profit firms, it risks a “brain drain” of its most talented graduates from the University of Iowa and Iowa State University. These individuals will increasingly look to Chicago, Minneapolis, or even Denver, where the capital environment for early-stage R&D is more favorable.²⁷

Stagnation in Targeted Sectors

The 2025 reforms specifically designated bioscience, advanced manufacturing, and tech/innovation as the future of Iowa’s economy.³ These sectors are characterized by high “upfront” costs and long research cycles before profitability is achieved.¹⁰ By reducing refundability during the most capital-intensive phase of a startup’s lifecycle, the state effectively “undercuts” its own strategic priorities. Without the cash flow provided by full refundability, many of Iowa’s promising medical device or AgTech prototypes may never reach the market.²

Erosion of the Innovation Ecosystem

Research and development do not happen in isolation. Successful startups create a “knowledge spillover” effect that benefits established Iowa companies, universities, and rural communities.¹⁰ As startups leave or fail due to liquidity constraints, this entire ecosystem weakens. The state loses not only the individual firms but also the specialized labor pools, shared laboratory resources, and the culture of innovation that attracts high-wage workers to the Midwest.⁵

Conclusion: A Strategic Path Forward

The 2026 transition to 60% refundability is a significant challenge for Iowa’s small-to-medium businesses, but it also presents an opportunity for the state to refine its economic development tools. By implementing an “Innovation Tier” with restored 100% refundability for small firms or establishing a “Tax Credit Transfer Marketplace,” the Iowa Legislature can achieve its goals of fiscal restraint and targeted growth without sacrificing its most promising innovators.

These solutions are not merely “carve-outs”; they are strategic corrections that acknowledge the unique capital needs of the startup sector. When coupled with the robust fraud prevention measures already established in the 2025 overhaul—including CPA verification and IEDA oversight—these changes will ensure that Iowa remains a national leader in the innovation economy. The cost of inaction—lost jobs, stalled research, and a migration of talent—far exceeds the modest investment required to preserve the liquidity of Iowa’s startup ecosystem.
