Reinvestment of Unused Credits
"Reinvestment" in the context of Arizona R&D credits refers to the strategic retention of unused tax credits via the 15-year carryforward provision to offset future liabilities, rather than electing a discounted refundable cash option.
⌬ Detailed Analysis
The Arizona Research and Development (R&D) tax credit is designed to incentivize innovation within the state. While the credit is primarily non-refundable, Arizona law (A.R.S. § 43-1168) provides a mechanism for handling "Unused Credits"—amounts that exceed a taxpayer's current year liability.
For most taxpayers, "Reinvestment" is the default and often most financially efficient path. It involves banking the excess credit to reduce tax bills in subsequent years (up to 15 years). This effectively "reinvests" the tax savings into the company's future cash flow by removing future tax burdens.
However, qualified small businesses (<150 employees) face a critical choice:
1. Immediate Liquidity (Refund): Cash out 75% of the excess, forfeiting the remaining 25%.
2. Reinvestment (Carryforward): Keep 100% of the excess for future use.

Local State Revenue Office (ADOR) & Statutes
A.R.S. § 43-1168 (Corporate) & § 43-1074.01 (Individual)
These statutes define the Research and Development Tax Credit. Crucially, they establish the carryforward period.
"If the allowable credit exceeds the taxes otherwise due... the amount of the claim not used to offset the taxes... may be carried forward for not more than fifteen consecutive taxable years as a credit against subsequent years' income tax liability."
A.R.S. § 41-1507 (Refundable Option)
Managed by the Arizona Commerce Authority (ACA). Allows Qualified Small Businesses (QSB) to exchange the carryforward for a refund.
- Condition: Must qualify as a QSB (under 150 employees).
- Penalty: The refund is issued at 75% of the credit value.
- Restriction: The remaining 25% is disallowed as a credit or carryforward (it is lost).
Arizona’s R&D Credit Reinvestment Program: Strategic Implementation and Compliance Guidance (A.R.S. § 43-1076)
Executive Summary: The Meaning of Reinvestment of Unused Credits
The Reinvestment of Unused Credits allows qualifying Arizona businesses to convert a portion of their existing, non-refundable Research and Development (R&D) credit carryforward into cash proceeds for specified in-state capital projects. This mechanism provides immediate liquidity for companies whose current or near-term tax liability is insufficient to utilize the full value of their accumulated R&D tax incentives.
This program, administered by the Arizona Commerce Authority (ACA), represents a strategic policy initiative designed to mobilize billions of dollars in dormant tax assets toward priority economic development goals, such as sustainability, capital investment in R&D infrastructure, and workforce development partnerships.1 By allowing the immediate conversion of future tax savings into current capital funding, the state fundamentally alters the financial dynamics of the R&D credit, transitioning it from a mere liability offset to an active instrument of industrial policy.
Section 1: Legislative Context and Strategic Program Overview
1.1 Foundation of the Arizona R&D Tax Credit
The Arizona R&D Tax Credit, enacted to encourage increased research activities within the state, offers taxpayers a substantial incentive against income tax liability.2 The credit calculation is tiered, designed to provide a greater proportional benefit for initial qualified expenditures. The credit is equal to $24\%$ of the first $\$2,500,000$ in qualified research expenses (QREs), plus $15\%$ of qualifying expenses that exceed $\$2,500,000$.1
If the amount of the calculated R&D Credit exceeds the taxpayer’s current income tax liability, the unused portion of the credit may generally be carried forward.1 The carryforward duration varies based on the year the credit was generated. For tax years beginning before January 1, 2022, unused credits could be carried forward for 15 consecutive taxable years.3 However, for tax years beginning on or after January 1, 2022, the amount of the claimed credit not used to offset taxes may be carried forward for 10 consecutive tax years.1 The nonrefundable portion of this credit remains primarily under the administration of the Arizona Department of Revenue (ADOR).1
1.2 Statutory Basis for Unused Credit Reinvestment
The Unused R&D Credit Reinvestment provision was established through subsequent legislation (e.g., Senate Bill 1643 and Senate Bill 1562) and was effective retroactively to July 1, 2022.1 This mechanism fundamentally enhances the R&D incentive structure by addressing the lack of immediate utility inherent in non-refundable carryforwards. The goal of this program is to mobilize the capital represented by these tax assets, which may otherwise expire if the taxpayer fails to generate sufficient tax liability within the carryforward window.1
The statute directs the ACA to accept, evaluate, and certify applications from taxpayers holding a balance of unused R&D Credit carryforward, enabling them to convert a portion of that asset into cash for specified investments.1 This formalized program signals the state’s commitment to ensuring that accrued R&D benefits translate into tangible, immediate economic development within Arizona.
1.3 Key Distinction: Reinvestment vs. Standard Refundable Credit
It is essential to distinguish the Unused Credit Reinvestment program from Arizona’s standard partial refundable R&D credit. The state utilizes two separate cash-out mechanisms administered by the ACA, each targeting different financial objectives and taxpayer profiles.
The standard refundable credit (A.R.S. §§ 43-1074.01; 43-1168) is generally limited to smaller businesses—those employing fewer than 150 full-time employees—and provides a partial refund of up to $75\%$ of the current year’s excess credit.1 The aggregate annual statewide cap for this standard refund was increased from $\$5$ million to $\$10$ million, with a maximum refund per taxpayer of $\$100,000$ in a single tax year.1
In contrast, the Reinvestment program targets the accumulated carryforward balance generated over potentially many years.5 While the standard refund supports small business operational cash flow, the Reinvestment program serves as a capital financing mechanism for large, strategic projects. Crucially, the Reinvestment program operates with a substantially higher per-taxpayer cap of $\$10$ million annually 1, and the explicit employee limit of 150 full-time employees applicable to the standard refund is not cited as a restriction for the Reinvestment program. Taxpayers must analyze their financial position to determine whether the higher percentage recovery of the standard refundable credit (if qualified) outweighs the massive liquidity potential offered by the reinvestment program.
Table 1 provides a clear comparison of these financial instruments:
Table 1: Comparison of Standard R&D Carryforward vs. Unused Credit Reinvestment
| Feature | Standard Non-Refundable Carryforward | Unused Credit Reinvestment Program |
| Goal | Offset future Arizona income tax liability | Generate capital for specific qualified investment projects |
| Value Realization | Dollar-for-dollar offset ($100\%$ value) | Conversion rate of $\$0.60$ per dollar ($60\%$ value) 1 |
| Liquidity | Low (realized only when tax liability exists) | High (provides immediate cash proceeds) |
| Expiration Period | 10 or 15 consecutive tax years 3 | Credit must be unexpired at the time of application 1 |
| Administration | Primarily Arizona Department of Revenue (ADOR) 1 | Arizona Commerce Authority (ACA) certification required 1 |
Section 2: The Core Mechanics and Statutory Limitations of Conversion
The core of the Reinvestment program involves the conversion of a non-liquid tax asset into tangible capital. This process is strictly governed by statutory conditions regarding the conversion rate, credit reduction, and administrative caps.
2.1 The Conversion Rate and Credit Reduction
The statutory condition requires that the R&D Credit be converted at the rate of $\$0.60$ per dollar.1 This formula dictates that for every $\$1.00$ of accumulated R&D credit converted, the taxpayer receives $\$0.60$ in cash proceeds. This represents a $40\%$ discount applied to the face value of the credit asset in exchange for immediate capital realization.
A critical requirement for compliance is the mandatory reduction of the taxpayer’s unused R&D credit carryforward balance. The statute specifies that the carryforward must be reduced by the full amount (100%) of the credits converted.1 This policy necessitates a sophisticated financial assessment by the taxpayer. The decision to forfeit $40\%$ of the credit’s future tax value for current liquidity is financially justifiable only if the internal rate of return (IRR) or the savings realized on the mandated reinvestment project exceed the cost of that $40\%$ discount, or if the risk of the credit expiring before utilization is high. The guaranteed, immediate nature of the capital must be weighed against the long-term, dollar-for-dollar value of a traditional tax carryforward.
2.2 Financial and Administrative Caps
The program includes specific limits designed to manage the state’s financial exposure and prioritize the allocation of funds.
The first limitation is the maximum amount an individual applicant may receive approval for in any single year. This taxpayer limit is $\$10,000,000$ in converted R&D credits.1
The second, and more significant, limitation is the aggregate state cap. The total amount of unused income tax credits that the ACA may approve for reinvestment is capped at $\$50,000,000$ per fiscal year.5 The legislature underscored the importance of this program by appropriating funds from the state General Fund (GF) specifically for implementation, including $\$50,000,000$ for the reinvestment itself in FY 2023.1 This appropriation was explicitly exempted from lapsing 1, confirming the program’s intent as a stable, persistent economic development mandate rather than a temporary funding measure.
The presence of a $\$50$ million state cap, coupled with a $\$10$ million per-taxpayer cap, fundamentally introduces competitive scarcity into the program. Since the fund can be fully exhausted by five large applicants, strategic financial planning dictates the necessity of aggressive and timely application. This competitive environment mirrors the first-come, first-served policy sometimes seen in other state incentive programs, meaning applications must be comprehensive and ready for immediate evaluation by the ACA to avoid being delayed until the next fiscal year’s allocation becomes available. Furthermore, only credits that are unexpired at the time of application are eligible for conversion.1
Section 3: Permissible Reinvestment Activities and Utilization Requirements
The cash proceeds generated from the conversion are not for general operating purposes; the statute mandates their use exclusively for five specified, high-priority investment categories within Arizona.1 Strict adherence to these utilization requirements is central to the program’s compliance.
3.1 Category 1: Sustainability or Water Capital Projects
This category encompasses capital expenditures focused on environmental stewardship, resource conservation, and resiliency, particularly relating to water management and infrastructure within the state. This provision aligns the tax incentive mechanism with Arizona’s long-term environmental and natural resource goals.
3.2 Category 2: Building or Updating R&D Facilities
Taxpayers may use the converted funds for capital expenditures dedicated to the construction, expansion, or modernization of their own research and development facilities in Arizona. This directly supports the growth of the state’s innovation infrastructure and complements the original intent of the R&D credit by facilitating future research activity.
3.3 Category 3: Capital Expenditure Projects with IHLs or CTEDs
Reinvestment funds can be used for projects involving capital outlay undertaken in formal collaboration between the taxpayer and an institution of higher learning (IHL) or a career technical education district (CTED).1 This requirement establishes a direct link between corporate financial incentives and the state’s academic and technical infrastructure.
3.4 Category 4: Workforce Development Projects with IHLs or CTEDs
This category covers projects specifically dedicated to workforce training and development, provided they are conducted jointly with an IHL or a CTED.1 By mandating investment in these partnerships, the policy promotes the growth of Arizona’s future workforce capacity and transforms the tax incentive into an active investment in human capital.
3.5 Category 5: Federally Supported Capital Projects
The final category covers any capital expenditure project that is supported by and utilizes matching monies from a federal program or a national grant program.1 This particular provision is highly strategic, as the state is implicitly incentivizing the maximization of external funding sources. The $\$0.60$ cash realized from the conversion effectively serves as state-provided matching funds, which can unlock substantially larger federal resources, creating a significant policy multiplier effect and minimizing the overall reliance on state funds for major infrastructure goals. This leverage mechanism represents a sophisticated governmental strategy to maximize the external financing of Arizona’s economic priorities.
Section 4: Local State Revenue Office Guidance and Administration
Successful implementation of the Reinvestment program requires seamless navigation between two distinct state administrative bodies: the Arizona Commerce Authority (ACA) for certification and the Arizona Department of Revenue (ADOR) for tax compliance and credit reduction.
4.1 The Role and Process of the Arizona Commerce Authority (ACA)
The ACA is the certifying authority for the Reinvestment program.1 Its responsibilities include:
- Application Processing: The ACA receives and evaluates applications for unused credit conversion. Taxpayers are instructed to apply electronically through the Authority’s Electronic Application System (EASY).8
- Project Viability and Certification: The ACA evaluates whether the taxpayer qualifies and whether the proposed project aligns with one of the five specified reinvestment categories. Upon approval, the ACA issues a Certification of Qualification.4
- Timeline and Deadlines: Taxpayers are generally instructed to apply to the ACA by December 31 of each taxable year.1 The competitive nature of the program, driven by the $\$50$ million annual cap, means that timely submission is critical, particularly since the application process often operates on a practical first-come, first-served basis for fund allocation.6
4.2 The Role and Compliance of the Arizona Department of Revenue (ADOR)
ADOR retains its primary role in administering the nonrefundable R&D tax credit (Form 308 for corporations/partnerships and Form 308-I for individuals) and monitoring general tax compliance.4 The interaction between the ACA and ADOR mandates a specific compliance sequence for the taxpayer.
Compliance Sequence: Taxpayers must receive the Certification of Qualification from the ACA prior to filing their tax return with ADOR for the tax year in which the converted credit amount is reduced.4 This strict prerequisite requires corporate tax directors to integrate the ACA’s economic development review process into their year-end financial closing schedule. The ACA certification timeline thus becomes the determining factor for the ADOR filing timeline, potentially superseding standard extension practices.
Credit Reduction Verification: ADOR’s critical compliance function is verifying that the taxpayer accurately reduced their reported R&D credit carryforward balance by the full $100\%$ of the amount certified for conversion by the ACA.1 This ensures that the tax asset is properly extinguished once the cash proceeds are secured.
Enforcement and Deficiency: If ADOR later determines through audit that a converted credit was incorrect or invalid (e.g., if the original Qualified Research Expenses calculation was flawed, or if the credit was claimed without proper ACA certification), the excess credit issued may be treated as a tax deficiency, subjecting the taxpayer to penalties and enforcement procedures.10 Because the conversion involves two agencies—ACA verifying project utilization and ADOR verifying historical credit generation—comprehensive documentation covering both the original R&D claim and the execution of the converted project is essential to mitigate future audit risk.
Section 5: Detailed Example: Modeling the Reinvestment Process
This example illustrates the financial impact of utilizing the Unused Credit Reinvestment program, detailing the conversion calculation and the resulting reduction in the tax asset.
5.1 Scenario Setup
- Taxpayer: Advanced Technology Corporation (ATC), a qualified R&D taxpayer.
- Tax Position: ATC has generated and accumulated substantial R&D credits over several years, resulting in a total unexpired R&D Credit Carryforward Balance of $\$35,000,000$.
- Project Goal: ATC plans a $\$10,000,000$ capital expenditure project to build and update its R&D facilities in Arizona (a project qualified under Category 2 of the permissible reinvestment activities).
- Application: ATC applies to the ACA to convert a portion of its carryforward balance to fund this critical infrastructure investment.
5.2 Application and Conversion Calculation
- Proposed Conversion: ATC requests to convert $\$15,000,000$ of its $\$35,000,000$ carryforward balance.
- ACA Approval: Because the maximum allowable conversion amount per taxpayer is capped at $\$10,000,000$ per year, the ACA certifies $$10,000,000 for conversion.1
- Cash Proceeds Calculation: The certified $\$10,000,000$ in credit is converted at the required $\$0.60$ per dollar rate.1
$$\text{Cash Proceeds} = \$10,000,000 \times 0.60 = \$6,000,000$$
5.3 Impact on Tax Asset and Financial Outcome
The conversion immediately impacts the taxpayer’s balance sheet, reducing the long-term deferred tax asset (the credit carryforward) while generating current liquidity.
Table 2: Financial Impact of Credit Reinvestment
| Description | Amount ($) | Calculation/Notes |
| Initial Unexpired R&D Credit Carryforward Balance | 35,000,000 | Total accumulated, non-liquid credit asset. |
| Amount of Credit Approved for Conversion | 10,000,000 | Limited by the statutory annual taxpayer cap. |
| Cash Proceeds Generated (Reinvestment Amount) | 6,000,000 | $(\$10,000,000 \times 0.60)$. Immediate capital. |
| Required Reduction of R&D Credit Carryforward | 10,000,000 | The full face value of the converted credit must be extinguished. |
| Remaining R&D Credit Carryforward Balance | 25,000,000 | New balance available to offset future tax liability for the remaining carryforward period. |
5.4 Summary of Financial Impact
ATC successfully secures $\$6,000,000$ in immediate, reliable capital to fund its R&D facility project, avoiding reliance on external financing or waiting years for tax liability to accrue. The corresponding R&D credit carryforward asset is reduced by the face value of $\$10,000,000$.
The effective financial trade-off for ATC is the loss of the ability to use the $\$4,000,000$ difference ($10M original credit value less $\$6 \text{M}$ cash received) to offset future taxes. This $\$4$ million represents the cost of liquidity. In capital budgeting terms, this cost is accepted because the immediate use of the $\$6$ million for the critical R&D facility upgrade is deemed more valuable than the delayed, uncertain realization of the full $\$10$ million tax offset over the remaining carryforward period.
Conclusion and Strategic Recommendations
The Arizona Reinvestment of Unused Credits program is a robust, politically supported mechanism designed to strategically monetize accumulated, non-liquid tax assets. It is a critical policy tool that shifts the benefit of R&D credits from a long-term liability offset to an immediate capital stimulus, particularly for large enterprises engaged in strategic in-state investment.
The success of utilizing this program hinges entirely on strategic timing and precise compliance with the dual administrative structures of the ACA and ADOR.
Strategic Compliance Roadmap:
- Secure Timely ACA Certification: Due to the strict $\$50$ million aggregate cap, the ACA application process is the primary constraint. Companies with large carryforwards should initiate the application process aggressively, well ahead of the December 31 deadline, to secure an allocation before the statewide fund is depleted by competitors.
- Conduct Rigorous Financial Modeling: The taxpayer must evaluate the net present value (NPV) of the converted cash proceeds against the long-term NPV of the $\$1.00$ face-value credit. The conversion should proceed only when the projected return on the mandated capital project sufficiently justifies the accepted $40\%$ discount (the cost of liquidity).
- Integrate Compliance Documentation: Comprehensive documentation must be maintained for both state agencies. This includes detailed evidence demonstrating the legitimacy of the original Qualified Research Expenses (QREs) used to generate the tax asset (for ADOR audit defense) and explicit proof that the converted funds were utilized exclusively for one of the five specified capital projects (for ACA compliance review).
Prioritize Leveraging Opportunities: Where possible, taxpayers should prioritize reinvestment projects that qualify under Category 5 (Federally Supported Capital Projects). The use of the converted state funds as matching capital amplifies the economic impact, effectively turning a discounted state tax asset into a catalyst for much larger external federal grants and maximizing the overall return on the R&D credit mechanism.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
