The Certificate of Qualification (CoQ)
"The CoQ is the mandatory authorization instrument that converts non-refundable Arizona R&D tax credits into immediate refundable cash for eligible small businesses."
In the context of the Arizona R&D Tax Credit program, most credits are non-refundable—meaning they can only offset tax liability. The Certificate of Qualification acts as a bridge, allowing companies with fewer than 150 employees to bypass this limitation and receive up to 75% of their credit as a direct refund from the state.

The CoQ is governed by specific Arizona Revised Statutes and Department of Revenue guidelines. Access the detailed guidance below.
Arizona Revised Statutes § 41-1507
This statute establishes the legal basis for the "Refundable research and development tax credit." Key provisions include:
- Authority: Grants the Arizona Commerce Authority (ACA) the power to process applications and certify eligibility to the Department of Revenue.
- The Cap: Explicitly sets the cumulative limit of refundable credits at $5,000,000 per calendar year.
- Qualification: Mandates that the taxpayer must employ fewer than 150 full-time employees worldwide on the last day of the taxable year.
- Refund Election: "If the amount of the credit exceeds the taxes otherwise due... the taxpayer may elect to have the excess refunded."
The Arizona Certificate of Qualification (CoQ): Strategic Compliance and Liquidity Management for R&D Tax Credit Refundability
I. Executive Overview: Defining the Certificate of Qualification (CoQ)
The Certificate of Qualification (CoQ) is an official authorization issued by the Arizona Commerce Authority (ACA) that establishes a small business’s eligibility for the state’s refundable portion of the Research & Development (R&D) tax credit. This document certifies the maximum refundable amount, enabling the taxpayer to convert a portion of their unused R&D credit into immediate operational cash flow from the State of Arizona.
1.1 The Context: Distinguishing Non-Refundable Use from Refundable Cash Recovery
The Arizona R&D tax credit, established in 1994 and currently authorized through the year 2030, is a key incentive designed to encourage investment in qualified research activities (QRAs) across vital state sectors, including technology, aerospace, biotechnology, and manufacturing.1 The program offers two pathways for benefit realization: a standard non-refundable credit and a specialized partial cash refund available only to a subset of businesses.1
For established, profitable firms, the credit operates non-refundably, offsetting Arizona income tax liability. Any unused, non-refundable credit balance may be carried forward for up to ten years for credits generated post-2021.1 The refundable mechanism, however, is reserved for Qualified Small Businesses (QSBS) and necessitates the issuance of the CoQ. This certification fundamentally transforms the credit’s utility for smaller, often cash-strapped companies by authorizing up to 75% of the unused credit to be paid out as a cash refund.1 This immediate liquidity injection allows high-growth firms that may not yet have significant tax liability to accelerate their innovation efforts. The process of securing the CoQ is, therefore, not merely a compliance step but a strategic financial mandate that provides crucial working capital.
1.2 Statutory Framework and Calculation Basis
The Arizona R&D credit statute, primarily found in Arizona Revised Statutes (ARS) § 43-1168, dictates that the calculation of the credit must adhere to the provisions of the Internal Revenue Code (IRC) § 41, with several critical state-specific adaptations.2 This alignment ensures that expenses categorized as Qualified Research Expenses (QREs)—including wages for employees performing or supervising research, supplies and prototypes, and 65% of contract research costs—are eligible, provided the research is conducted solely within Arizona.1
A crucial requirement for Arizona taxpayers is the mandatory application of the federal regular credit computation method.2 Unlike federal law, which permits the use of the alternative simplified credit (ASC), Arizona explicitly prohibits this method. This requirement means that taxpayers must calculate the complex “base amount” defined in IRC § 41(c), which is based on the average annual Arizona gross receipts for the four preceding taxable years.4 For startups and small businesses, preparing this historical data to calculate the base amount imposes a substantial documentation and computational burden that must be finalized before the CoQ application can be submitted to the ACA.
II. The Arizona R&D Credit Statutory Foundation and Calculation
The CoQ authorizes the partial refund based on the total credit generated by the taxpayer, which is determined by a tiered rate structure applied to the excess QREs.
2.1 Arizona’s Tiered Rate Structure
The allowable credit amount is calculated as a percentage of the excess of the current year’s Arizona QREs over the established base amount, plus Arizona basic research payments.2 Arizona utilizes a tiered approach to incentivize varying scales of research investment.
For taxable years beginning before December 31, 2030, the rate structure is as follows: the credit is 24% of the first $2,500,000 in excess QREs.1 For any excess QREs surpassing the $2,500,000 threshold, the credit drops to 15%.1 This tiered system encourages top utilization by mid-sized firms that maximize the initial 24% rate.1
It is essential to note the statutory sunset provisions. After December 31, 2030, the rates decrease significantly. The initial tier rate drops from 24% to 20%, and the subsequent tier rate falls from 15% to 11%.3 Taxpayers should consider the time horizon of these rates when projecting the value of credit carryforwards extending beyond the 2030 sunset date.
The table below summarizes the current and planned R&D credit rate structures:
Arizona R&D Tax Credit Rate Structure (ARS § 43-1168)
| Excess QRE Threshold | Rate (Before 12/31/2030) | Credit Calculation | Rate (After 12/31/2030) |
| Up to $2,500,000 | 24% | 24% of the amount | 20% |
| Above $2,500,000 | 15% | $600,000 + 15% of the excess | $500,000 + 11% of the excess |
2.2 Additional Credit for University Basic Research
Arizona offers an additional incentive for taxpayers that make basic research payments to a university under the jurisdiction of the Arizona Board of Regents (e.g., Arizona State University, Northern Arizona University, or the University of Arizona).6 This supplementary credit is equal to 10% of the amount of basic research payments that exceed the qualified organization base period amount.3 This additional credit is subject to a calendar year aggregate cap of $10,000,000.3
Securing this specific university research credit also requires a form of certification. Taxpayers must obtain a separate letter of certification from the ACA and a letter of approval certifying the credit amount from the Arizona Department of Revenue (ADOR).7 This dual certification requirement for basic research payments highlights the state’s bifurcated approach to managing R&D incentives—the ACA handles initial certification, while ADOR manages final approval and disbursement.
III. The CoQ as a Prerequisite for Refundability
The Certificate of Qualification is the critical document that grants a QSBS access to the cash value of its R&D investment.
3.1 Defining the Qualified Small Business
Eligibility for the partial refund is strictly controlled to ensure the benefit targets the intended small business demographic. To qualify for the refundable portion, a company must first qualify for the non-refundable credit and meet a size threshold. Specifically, the business must certify that it employs fewer than 150 full-time employees.1 Upon application to the ACA, the business must also pay a 1% application fee.1
3.2 The Refund Calculation and Financial Caps
The CoQ confirms the maximum amount of cash refund a QSBS can receive. The refund amount is limited to 75% of the allowable credit that exceeds the taxpayer’s liability for the taxable year.1 This conversion rate provides substantial liquidity.
However, the liquidity benefit is subject to two crucial caps:
- Individual Taxpayer Cap: The maximum refund amount authorized by the ACA for any single taxpayer in one tax year is strictly capped at $100,000.8
- Statewide Aggregate Cap: The ACA is authorized to approve refunds up to an aggregate annual cap. This cap has historically been $5,000,000.1 Recent legislative activity indicates an increase to $10,000,000 in the aggregate annual cap for the refundable portion, providing a larger potential pool for applicants.11
The individual $100,000 cap is a key strategic limitation. If a QSBS generates a total credit that results in a calculated refundable portion (75% of the excess credit) exceeding $100,000, the CoQ will only authorize the $100,000 maximum. The amount of the calculated refundable credit that exceeds the $100,000 cap is automatically converted back into a non-refundable credit carryforward, which can be utilized against future tax liabilities.1 Therefore, companies generating significant credits must prioritize securing the maximum immediate cash refund while managing the remainder as a future tax asset.
IV. Agency Guidance: Navigating the ACA Application Process
The Arizona Commerce Authority (ACA) is the governing body responsible for administering the refundable credit program and issuing the CoQ. The process is characterized by competitive timing due to the aggregate statewide cap.
4.1 ACA Jurisdiction and the Electronic Application System (EASY)
The ACA utilizes the Electronic Application System (EASY) for all refundable tax credit submissions.10 This system processes applications based on a highly sensitive timeline. A fundamental requirement for the application is that it must be based on actual numbers, not estimates.10 This necessitates that the QSBS has finalized its QRE aggregation and calculated its final credit amounts according to the complex Regular Credit Method before application submission.
4.2 Critical Timing and Prioritization
The competitive nature of the refundable credit pool demands strict adherence to filing deadlines and procedures. Historically, demand has exceeded the $5 million cap (for example, in the 2022 tax year, taxpayers requested over $6.7 million in refunds).8
- Calendar Year Taxpayers: Applications may be filed on or after the first business day following the close of the calendar year.1
- Fiscal Year Taxpayers: Applications may be filed on or after the first business day after the end of the fiscal year.10
Applications are generally processed on a first-come, first-served (FCFS) basis, according to the date and time stamp provided by the EASY system.10 However, the volume of applications typically received on the very first business day of the calendar year necessitates a specific mechanism for fairness: applications received by 11:59 p.m. (Arizona time) on that day are prioritized through a random selection process (lottery).10
A crucial administrative constraint is that a taxpayer must NOT have filed its tax return with Revenue for the tax year in which the R&D credit was generated prior to applying for the partial refund.10
The existence of the lottery on Day 1 underscores the extreme importance of preparedness. Businesses must complete their intricate R&D credit computations (which rely on historical data for the base amount) almost instantaneously following the close of the tax year. Failing to submit a “substantially complete application” on the first business day immediately subjects the taxpayer to the higher risk of FCFS processing after the lottery, increasing the likelihood that the aggregate statewide cap will be exhausted before their application can be reviewed and certified.10
4.3 Key Limitations and Procedural Requirements
The following table synthesizes the essential parameters that govern the ACA Refund Program, reflecting the strategic planning required to successfully secure the CoQ:
ACA R&D Refund Program Key Parameters and Risk Factors
| Parameter | Requirement | Source | Impact/Risk |
| Employee Limit | Fewer than 150 full-time employees | 1 | Primary eligibility constraint. |
| Refund Rate | 75% of excess allowable credit | 3 | Determines cash conversion ratio. |
| Maximum Individual Refund | $100,000 | 10 | Hard cap on immediate cash benefit; converts excess calculated refund into carryforward. |
| Statewide Aggregate Cap | Historically $5M, potentially increasing to $10M | 10 | High risk of exclusion if not submitted timely on Day 1. |
| Application Method | Electronic Application System (EASY) | 10 | Requires specific system familiarity and electronic submission. |
| Priority Mechanism | Lottery on Day 1; FCFS thereafter | 10 | Mandates immediate post-year-end calculation and application submission. |
| Filing Constraint | Must not have filed tax return with ADOR | 10 | Requires precise coordination between R&D application and tax filing schedules. |
V. ADOR Compliance: Integrating the CoQ into the Tax Return
The Arizona Department of Revenue (ADOR) is responsible for processing the refund request once the CoQ has been issued by the ACA. The CoQ serves as the legal authorization for ADOR to initiate the payment.
5.1 Required Documentation and Tax Form Integration
To finalize the claim, the taxpayer must submit a copy of the ACA’s Certificate of Qualification to the ADOR along with the income tax return (e.g., corporate Form 308 or individual Form 308-I).3
The authorized refund amount specified on the CoQ must be explicitly reported on the ADOR tax forms. On Form 308 (Credit for Increased Research Activities), the taxpayer must confirm that the credit is refundable and then enter the “maximum refund amount authorized by the ACA” onto designated lines, such as Part 1, Line 2a2, and Part 5.14 This strict administrative process ensures that the amount claimed on the tax return precisely matches the amount certified by the ACA under the competitive cap structure.
5.2 Legal Setoff Provisions
A critical procedural reality is that the issuance of the CoQ does not guarantee an immediate, full cash disbursement. The Arizona Revised Statutes provide that the refund is subject to setoff under ARS § 42-1122.3 This statute permits the ADOR to reduce or intercept the tax refund payment to satisfy any outstanding tax liabilities, penalties, or debts owed by the taxpayer to the State of Arizona or its agencies.
For a QSBS, this requirement necessitates meticulous financial management. If the company is relying on the full $100,000 cash injection for operating purposes, any unaddressed or unexpected state tax liability (e.g., unpaid transaction privilege tax, payroll tax, or other fines) could result in the refund being partially or entirely withheld. Therefore, concurrent with the competitive CoQ application process, the company must conduct a comprehensive review of all state accounts to ensure no liabilities exist that would impede the final cash recovery.
VI. Detailed Case Study: A Small Business R&D Refund Scenario
To illustrate the interplay between the statutory calculation, the 75% refund rate, and the $100,000 individual cap established by the CoQ, consider the hypothetical case of Alpha Innovate, a growing technology firm.
6.1 Scenario Setup: Alpha Innovate
Alpha Innovate is a QSBS that invested heavily in new product development during the 2024 tax year.
| Metric | Value | Rationale |
| Taxable Year | 2024 (Pre-2030 Rate) | Utilizes the 24% rate on the lower threshold. |
| Employee Count | 120 FTEs | Qualifies as a QSBS (must be < 150 employees). |
| Arizona QREs (Current Year) | $1,800,000 | Total QREs incurred in Arizona. |
| Base Amount (Regular Method) | $200,000 | Historically calculated per IRC § 41(c) mandate. |
| Arizona Income Tax Liability | $60,000 | Current liability, common for profitable, but still growing firms. |
6.2 Step-by-Step Calculation of the CoQ-Authorized Refund
Alpha Innovate must calculate its total allowable credit using the Regular Credit Computation Method before submitting its application to the ACA via EASY.
Example of Arizona Refundable R&D Credit Calculation (Illustrative)
| Step | Calculation Component | Value ($) | Statutory Basis / Impact |
|—|—|—|
| 1 | Excess QREs (Basis for Credit) | $1,600,000 | QREs ($1.8M) minus Base Amount ($0.2M). |
| 2 | Total Allowable R&D Credit (24%) | $384,000 | 24% of $1,600,000 (below the $2.5M threshold).3 |
| 3 | Non-Refundable Credit Used (Offset) | $60,000 | Offsets 100% of current Arizona tax liability. |
| 4 | Remaining Excess Credit | $324,000 | $384,000 (Total Credit) – $60,000 (Used Credit). |
| 5 | Calculated Refundable Portion (75% of Excess) | $243,000 | 75% of $324,000 (This is the potential cash refund amount). |
| 6 | Maximum Refund Authorized by ACA (CoQ) | $100,000 | Limited by the statutory individual per-taxpayer cap.10 This is the figure certified by the CoQ. |
| 7 | Non-Refundable Credit Carryforward (Remaining) | $224,000 | $384,000 (Total Credit) – $60,000 (Used) – $100,000 (Refunded). This amount is carried forward for up to 10 years.1 |
6.3 Interpretation and CoQ Impact
In this scenario, Alpha Innovate successfully secures its CoQ by applying on time and being selected under the available statewide cap. Although the calculation generated a potential refundable credit of $243,000, the CoQ caps this amount at $100,000, which is the figure subsequently entered on Form 308.14
The strategic implication here is pronounced: $143,000 of the calculated refundable credit ($243,000 calculated minus $100,000 received) is immediately converted into a less liquid, long-term non-refundable carryforward. The CoQ facilitates $100,000 in immediate, non-dilutive capital, but it simultaneously forces a careful assessment of the utility of the remaining $224,000 carryforward asset over the next decade.
VII. Strategic and Legal Implications of the Certificate of Qualification
7.1 Documentation Rigor and Audit Preparation
The stringent procedural requirements for securing the CoQ inherently necessitate a heightened level of documentation rigor. The ACA’s demand for “actual numbers” immediately following year-end 10 means that the preparation of all supporting documents—including detailed project descriptions, time tracking records for involved employees, invoices for supplies, and contracts for external research—must be completed contemporaneously with the research activities.
Furthermore, the documentation must satisfy not only Arizona’s requirements but also the underlying federal standards of IRC § 41, which the state adopts.2 For a valid R&D credit claim, the taxpayer must be prepared to identify all business components to which the credit relates, the specific research activities performed, the individuals involved, the information sought to be discovered, and detailed expense categories (wages, supplies, contract research).15 This level of preparation ensures that the underlying QREs supporting the CoQ are defensible in the event of a future audit by ADOR or the IRS.
7.2 Managing Dual Certification for University Research
For QSBS that engage in basic research with state universities, the process involves navigating two related but distinct certification programs. As noted in Section II.2, the 10% additional university research credit requires a separate certification letter from the ACA and subsequent approval from the ADOR.7
The potential for dual certification adds complexity, requiring the meticulous segmentation of basic research payments from general QREs. Strategic planning is necessary to ensure that the claims do not exceed the specific financial limits and aggregate caps associated with each incentive program (the $100,000 cap for the standard refundable credit versus the $10,000,000 calendar year cap for the university basic research credit).3 Effective compliance demands that both certifications be pursued in parallel, understanding that their successful achievement relies on distinct application pathways within the ACA’s system.
VIII. Conclusion: The Strategic Value and Compliance Imperatives of the CoQ
The Certificate of Qualification represents the critical juncture where Arizona’s R&D tax policy transforms into tangible economic support for Qualified Small Businesses. The CoQ is far more than a simple receipt; it is the official state authorization required to convert a non-refundable tax asset into up to $100,000 of immediate, high-value working capital.
The exhaustive analysis of state revenue office guidance reveals that compliance for the CoQ is driven by competitive timing and computational accuracy, placing unique demands on QSBS filing teams.
To successfully secure and monetize the R&D credit through the CoQ, firms must adhere to the following non-negotiable compliance imperatives:
- Mandatory Computational Adherence: The taxpayer must rigorously comply with the Regular Credit Computation Method mandated by ARS § 43-1168, relying on actual, auditable QRE data and historical base period calculations, explicitly excluding the federal Alternative Simplified Credit.2
- Immediate Application Priority: Due to the severe competition for the limited aggregate pool (historically $5 million, though potentially rising), a substantially complete application must be filed via the ACA’s EASY system on the first business day following the close of the tax year to maximize the probability of receiving a CoQ through the initial lottery process.10
- Coordinated ADOR Submission: The final claim requires submitting a copy of the CoQ, detailing the ACA-authorized refund amount, with ADOR Form 308.14 This filing must be precisely coordinated to occur after CoQ issuance but before the main income tax return is filed.
- Mitigation of Setoff Risk: Prior to filing, the taxpayer must confirm that no outstanding liabilities exist with any state agency, as the eventual cash refund remains subject to the setoff authority of ADOR under ARS § 42-1122, posing a final risk to the expected liquidity.3
The Certificate of Qualification is thus the linchpin of the Arizona refundable R&D credit, requiring swift, accurate execution under a high-stakes, competitive regulatory framework to deliver maximum financial benefit to innovative Arizona businesses.

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.
