R&D Tax Credit | ASC Election
The Core Definition
The Alternative Simplified Credit (ASC) election allows Arizona taxpayers to calculate their R&D tax credit based on recent spending trends (prior 3 years) rather than a fixed historical base, simplifying compliance for mature companies.
Primary Statute
A.R.S. § 43-1168
Governs the corporate credit & ASC election specifics.
AZ Credit Rate (Tier 1)
24%
Applied to the first $2.5M of the calculated Excess.
AZ Credit Rate (Tier 2)
15%
Applied to any Excess amount over $2.5M.
Concept: Trend vs. Fixed Base
The ASC rewards increasing research spend over a short-term moving average.
Why Choose ASC?
-
1
Documentation Simplicity
Avoids the need to substantiate records from the 1980s (Fixed Base methodology).
-
2
Federal Conformity
Arizona generally follows the federal election. If you elect ASC federally, you typically utilize the ASC method for Arizona.
-
3
Recent Growth
Ideal for companies with high recent spending but who may not exceed the high "Fixed Base" percentage of the Regular method.
Detailed Report: Arizona ASC Election
1. Context & Overview
The Arizona Research & Development (R&D) Tax Credit is a lucrative incentive designed to spur technological innovation within the state. While modeled after the federal Section 41 credit, Arizona applies its own specific rates and refundability options.
The Alternative Simplified Credit (ASC) is a methodology introduced to provide a more current-year relevant calculation. Unlike the "Regular" method, which relies on a "Fixed Base Percentage" often tied to gross receipts and aggregate QREs from the 1984-1988 period, the ASC looks only at the prior three tax years.
2. Statutory Framework
"If the taxpayer makes an election for the taxable year to calculate the federal credit... using the alternative simplified credit method... the taxpayer shall calculate the credit under this section... using the alternative simplified credit method."
— A.R.S. § 43-1168(D) & A.R.S. § 43-1074.01(D)
This "piggyback" provision means that for most taxpayers, the federal election binds the state method. However, if no federal credit is claimed, a separate Arizona election can be made on Arizona Form 308.
3. Calculation Mechanics
The Arizona ASC differs from the Federal ASC in the final application of rates. The calculation steps are as follows:
- Step A: Determine Qualified Research Expenses (QREs) for the current year.
- Step B: Determine the average QREs for the three preceding taxable years.
- Step C (The Base): Calculate 50% of the average from Step B.
- Step D (The Excess): Subtract the Base (Step C) from Current QREs (Step A). This is the "Arizona ASC Excess."
- Step E (The Credit): Apply Arizona's tiered rates to the Excess:
- — 24% on the first $2.5 million of Excess.
- — 15% on any Excess over $2.5 million.
4. Refundability (The ACA Boost)
A unique feature of the Arizona credit is partial refundability for small businesses certified by the Arizona Commerce Authority (ACA). While the ASC method determines the amount of the credit, the ACA certification determines how it is used (offsetting tax vs. cash refund).
The refundable portion is limited to 75% of the excess credit calculated, capped at a maximum refund amount per taxpayer.

State Guidance & Statutes
Official references for the Arizona ASC election.
Subsection D specifically addresses the method of calculation. It mandates that if the taxpayer elects the federal ASC method under IRC § 41(c)(4), they must use the equivalent Arizona calculation for the state credit. This ensures consistency between federal and state filings.
Form 308 is the primary form for claiming the R&D credit. The instructions clarify that the "Base Amount" for ASC filers is 50% of the average of the prior three years' QREs. It also provides the worksheet for applying the 24% and 15% tiered rates to the excess amount.
This statute outlines the Arizona Commerce Authority (ACA) certification process. While the tax credit is calculated via Title 43, the *refundability* is governed here. A taxpayer must obtain a certificate from the ACA to treat the credit as refundable. The refund is limited to 75% of the excess credit calculated.
The Alternative Simplified Credit (ASC) Election in Arizona: Navigating State Statutory Compliance for R&D Tax Incentives
I. Executive Summary: The Strategic Value of the Arizona R&D Tax Credit
The Alternative Simplified Credit (ASC) Election provides an alternative, often simpler, method for calculating the federal R&D tax credit based on a taxpayer’s average Qualified Research Expenses (QREs) over the preceding three years. Arizona adopted the ASC calculation methodology for its state R&D tax credit effective for tax years beginning in 2023, offering taxpayers enhanced flexibility and potentially a significantly superior benefit compared to the traditional Regular Credit method.1
The state of Arizona strategically employs the Research and Development (R&D) tax credit program, authorized under A.R.S. § 43-1168, as a core component of its economic development strategy, specifically designed to encourage increased research and development activities within the state.2 This incentive is particularly valuable for the state’s high-tech and manufacturing sectors, fostering investment in the development or improvement of technologies, products, materials, and processes.1 The financial significance of this program is substantial, with preliminary data indicating that total corporate R&D tax credits used or refunded amounted to approximately $163,699,286 in Tax Year 2022.4
Initial Decision Matrix: When to Elect ASC over the Regular Credit
Taxpayers face a critical initial decision regarding the methodology used to compute the credit: the Regular Credit method or the ASC method. The traditional Regular Research Credit (RRC) requires a base amount calculation that relies on both Qualified Research Expenses (QREs) and historical gross receipts data extending back as far as five years.5 Companies often select the ASC method when they lack the extensive historical records necessary to fully document the fixed-base percentage component required for the Regular Credit calculation.5
The ASC simplifies the compliance burden by basing the credit calculation solely on the average QREs incurred over the three preceding tax years.7 This flexibility is particularly advantageous for growing businesses with varying QRE histories. While the ASC provides computational ease, the decision to elect ASC over the Regular Credit should ultimately be driven by a side-by-side calculation. The analysis should determine which method yields the maximized credit amount based on the company’s specific QRE history relative to the respective base amounts established by the different calculation methodologies.
II. Federal Foundation: Understanding the Alternative Simplified Credit (ASC)
The Arizona R&D tax credit is structurally linked to the federal framework established under Internal Revenue Code (IRC) Section 41. Arizona’s statute explicitly allows the credit in an amount computed pursuant to IRC § 41, subject only to specific state-level exceptions.1 Therefore, a comprehensive understanding of the federal ASC is foundational to navigating the Arizona credit.
The Regular Credit vs. The ASC: A History of Simplification
The original R&D credit methodology, known as the Regular Research Credit (RRC), utilizes a complex base calculation. This base is determined by multiplying a “fixed-base percentage” by the taxpayer’s average annual gross receipts for the four preceding tax years.6 The fixed-base percentage is derived from the ratio of qualified research expenses to gross receipts during an initial “base period.” Due to the complexity of establishing this historical base, particularly for younger or rapidly evolving companies, the federal government introduced the ASC method.
The ASC method, codified federally since 2009 under IRC § 41(c)(5), was designed to simplify the process and increase accessibility, particularly for businesses that struggled to meet the stringent historical documentation requirements of the RRC.5
Detailed Federal ASC Calculation Methodology
The federal ASC calculation follows a standardized four-step process 5:
- Calculate Average QREs: The taxpayer identifies and calculates the average Qualified Research Expenses (QREs) for the three taxable years immediately preceding the current tax year.
- Determine the Base: The ASC base amount is defined as 50% of the average QREs calculated in the first step.
- Calculate the Excess: This base amount (50% of the three-year average) is subtracted from the QREs incurred in the current tax year.
- Compute the Credit: The federal credit is calculated as 14% of the resulting excess QREs.
A significant provision in the federal ASC structure addresses startups: if a taxpayer had no QREs during any of those three prior years, the federal credit is calculated using a simplified 6% rate applied directly to the QREs in the current tax year.5
The design of the ASC inherently incentivizes companies to increase their research expenditures year-over-year. A company whose current year QREs are substantially greater than their three-year average will realize a larger credit, as the excess expense used to calculate the credit is magnified. This structure strongly encourages substantial incremental growth in R&D investment.5
III. The Arizona R&D Tax Credit Landscape (A.R.S. § 43-1168)
Arizona’s statute, A.R.S. § 43-1168, governs the state research and development income tax credit for corporations and adopts the fundamental calculation framework of IRC § 41, but mandates crucial modifications that tailor the incentive to state economic goals.1
Defining Arizona Qualified Research Expenses (QREs): The In-State Requirement
The foremost restriction Arizona imposes on the definition of QREs is geographical. For purposes of the state credit, qualified research includes only research conducted within Arizona.8 This means that while the fundamental technical definition of “qualified research” (the Four-Part Test) remains aligned with federal law, the associated wages, supplies, and contract research costs must be physically incurred for research performed inside the state’s borders. This includes research conducted at an Arizona university paid for by the taxpayer, which is explicitly permitted.8 This territorial limitation is a critical factor in compliance and represents a distinct area of audit focus for the Arizona Department of Revenue (AZDOR).
Historical Context and Modernization
The Arizona R&D credit program has evolved significantly since its inception. While older statutory language detailed fixed, annual maximum allowable credit caps—starting at $\$100,000$ for the first taxable year and potentially increasing up to $\$500,000$ after the third taxable year—these limitations have been superseded by modern legislative amendments.8
The contemporary structure confirms a strategic legislative pivot: Arizona moved away from a capped, modest incentive program toward a scalable, aggressive incentive mechanism that directly rewards large, sustained investment. The termination provisions of IRC § 41, which might otherwise limit the credit’s duration, are explicitly stated not to apply to the Arizona credit, ensuring its permanence.8
Arizona’s Unique Tiered Credit Rate Structure
The most powerful distinction between the Arizona and federal R&D credits lies in the applicable credit rate. Whether a taxpayer chooses the Regular Credit method or the ASC method to determine the “excess QREs” (the amount exceeding the calculated base), the state applies its own aggressive tiered rate structure.1
- Tier 1 (Aggressive Incentive): The allowable credit is 24% of the excess QREs, applied to the amount up to $\$2,500,000$.1 This rate is substantially higher than the 14% federal ASC rate, highlighting the state’s aggressive fiscal push for research activity.
- Tier 2 (Sustained Incentive): If the allowable excess QREs exceed $\$2,500,000$, the credit amount is calculated as $\$600,000$ (representing 24% of the first $\$2.5$ million) plus 15% of the amount of expenses over the $\$2.5$ million threshold.1
Carryforward Rules
For any portion of the non-refundable credit that exceeds the current year’s tax liability, the unused amount may be carried forward. For taxable years beginning from and after December 31, 2021, the excess credit can be carried forward for the next ten consecutive taxable years.3 This represents a reduction from the previous 15-year carryforward period applicable to earlier tax years.3
IV. Arizona’s Adoption and Application of the ASC Election
Effective for tax years ended on or after December 31, 2023, Arizona began permitting taxpayers to compute the Credit for Increased Research Activities using the Alternative Simplified Credit (ASC) method.1 This change was implemented to enhance flexibility and simplify the computational burden for established businesses.
The Hybrid Calculation Strategy
Arizona’s ASC is a hybrid calculation that leverages the simplified base methodology of the federal ASC while retaining the state’s high, tiered credit rates. The calculation proceeds as follows 7:
- ASC Base Determination: The base amount is calculated as 50% of the average Arizona QREs incurred during the three taxable years immediately preceding the current year. If a taxpayer had no prior QREs, the base is zero.
- Excess QREs Calculation: The calculated base amount is subtracted from the current year’s Arizona-sourced QREs.
- Arizona Rate Application: The resulting excess QREs are then subject to the state’s tiered rate structure (24% up to $\$2.5$ million, then 15% thereafter).
Critical Eligibility Restriction: The AZ Zero-QRE Prohibition
A critical statutory deviation exists between the federal and Arizona rules concerning ASC eligibility, primarily impacting new or first-time claimants.
Under federal law, a taxpayer with zero QREs in the three preceding years is still eligible for the federal ASC, albeit at a reduced 6% rate applied to the current year’s QREs.5
However, the Arizona Department of Revenue (AZDOR) guidance specifies a stringent requirement for the state ASC election: If the taxpayer has no qualified research expenses (QREs) in any of the three (3) prior taxable years, the taxpayer does not qualify for the Arizona ASC.10 This rule eliminates the state ASC option for true startups or companies with no history of QREs.
The implication of this restriction is significant: companies that are attempting to claim the R&D credit for the first time or those that had a zero base in any of the three preceding years are precluded from utilizing the simpler ASC method. These taxpayers are instead obligated to compute their Arizona credit using the historically more complex Regular Credit method, requiring them to document a fixed-base percentage derived from historical QREs and gross receipts, even if they could have utilized the ASC federally. This structural difference restricts the ASC option to companies that demonstrate a consistent pattern of at least some historical R&D investment in Arizona.
The following table summarizes the strategic differences between the two methods available in Arizona:
Table Title: Comparative Analysis: Arizona R&D Credit Methods
| Feature | Regular Credit Method | Alternative Simplified Credit (ASC) Method |
| Statutory Basis | A.R.S. § 43-1168 adopting IRC § 41 RRC structure 8 | A.R.S. § 43-1168 adopting IRC § 41 ASC structure 1 |
| Base Calculation | Fixed-Base Percentage × 4-Year Average Gross Receipts (Minimum 50% of Current QREs) 7 | 50% of Average QREs for the Prior 3 Years 5 |
| Arizona Eligibility | Requires documentation of historical QREs and Gross Receipts. | Ineligible if zero QREs in any of the 3 prior years 11 |
| Arizona Credit Rates | Tier 1: 24% (up to $\$2.5\text{M}$ Excess); Tier 2: 15% (over $\$2.5\text{M}$ Excess) 7 | Tier 1: 24% (up to $\$2.5\text{M}$ Excess); Tier 2: 15% (over $\$2.5\text{M}$ Excess) 7 |
V. AZDOR Compliance: Navigating the Filing Requirements
The claiming of the Arizona R&D tax credit is administered by the Arizona Department of Revenue (AZDOR) primarily through Form 308-I, Credit for Increased Research Activities.9 Specific instructions govern how taxpayers must elect and compute the credit using the ASC method.
The ASC Election Procedure
Taxpayers who choose to claim the ASC must make this election clearly on their state return. This is accomplished by checking the designated “ASC” box located on the top of Form 308-I.11 The selection of the ASC is determinative for the subsequent computational parts of the form.
Computation on Form 308-I
If the ASC election is made, the taxpayer is directed to complete a specific section of the form dedicated to the alternative calculation. Taxpayers must complete Part 12, lines 75 through 93, which constitutes the specialized worksheet for computing the ASC.9 Once the total credit amount is derived from line 93 of Part 12, that figure is carried forward and entered onto Part 2, line 27b, for use in calculating the final tax liability reduction.9 If the taxpayer instead elects the Regular Credit, they must complete Part 2, lines 8 through 27a.9
Taxpayer Type Differentiation
The detailed instructions for Form 308-I clarify that the starting point for calculating current year QREs varies based on the taxpayer’s entity type 9:
- Corporate Taxpayers (excluding S Corporations, personal holding companies, and service organizations): These entities electing the ASC are instructed to begin their computation on line 75, which focuses on Basic research payments paid or incurred to qualified organizations.9
- All Other Taxpayers (including S Corporations and partnerships): These entities begin their current year QRE computation on line 78, which relates to Current Year Wages for Qualified Services.9
This differentiated approach ensures that the federal basic research payment deduction components, which apply primarily to C Corporations, are correctly integrated into the state filing structure, adding a necessary layer of complexity for specialized tax teams.9
Treatment of Contract Research and University Payments
Arizona maintains specific rules for contract research expenses. Only 65% of any amount paid or incurred for qualified research performed in Arizona on the taxpayer’s behalf is eligible for inclusion in QREs.11 Furthermore, contract research expenses paid to an Arizona university under the Arizona Board of Regents, if they qualify as basic research payments, may entitle the taxpayer to an additional credit, which is claimed separately via Form 346.11
Pro Rata Claims for Pass-Through Entities
For tax liability reduction purposes, two or more corporate taxpayers that share in the eligible expenses may claim their pro rata shares of the tax credit.8 For pass-through entities, such as S Corporations and partnerships, the entity itself must file Form 308-I and allocate the calculated credit amount to its shareholders or partners on a proportional basis.11
VI. The Critical Factor of Refundability and the ACA Process
The Arizona R&D tax credit offers a significant advantage in that it is both non-refundable (used to offset current tax liability) and, under certain conditions, partially refundable (providing a cash refund for the excess credit).3 However, the process for obtaining the refundable portion is governed by stringent requirements that involve a separate state authority.
Mandatory Pre-Approval Requirement
Unlike a standard tax election, the refundable option is not automatically granted upon filing with AZDOR. To qualify for a refund, the taxpayer must first submit an application to the Arizona Commerce Authority (ACA) and receive a Certificate of Qualification before the tax return claiming the credit is filed.3
This mandated two-step process—requiring approval from an economic development agency (ACA) before final filing with the revenue department (AZDOR)—demonstrates a strategic effort by the state to control the cash outlay associated with the refundable portion of the incentive. The ACA reviews the application to ensure compliance with economic development standards before issuing the certificate specifying the maximum refundable amount.10
Eligibility Thresholds for Refundability
To be eligible for the refundable portion of the credit, the taxpayer must meet a key size criterion: the entity must employ fewer than 150 full-time employees.10 This restriction targets the most aggressive cash-back incentive toward Small and Medium-sized Enterprises (SMEs) that the state seeks to stimulate.
Additionally, the taxpayer must designate the election to make the credit refundable on the original filed tax return claiming the current year’s credit.10 This election cannot be made retroactively on an amended return. When pass-through entities, such as S Corporations or partnerships, seek the refund, the entity must apply for the Certificate on behalf of its shareholders or partners.11
Calculating the Refundable Excess Credit
The portion of the credit that may be refunded is calculated only after the credit has been applied against the current year’s tax liability. The “excess credit” is defined as the current year’s credit amount reduced by the current year’s tax liability.10
The refundable amount is then capped, determined as the lesser of two specific limitations 10:
- Seventy-five percent (75%) of the current year’s excess credit.
- The maximum refundable amount specified on the Certificate of Qualification issued by the ACA.
The 75% cap acts as a fiscal control mechanism, ensuring that the state retains 25% of the calculated excess credit amount, thereby limiting the state’s potential cash exposure, irrespective of the maximum amount approved by the ACA.10 The calculation of the refund is carried out after the tax liability is determined.11
VII. Numerical Implementation Example: Arizona ASC Election in Practice
To illustrate the powerful combination of the simplified ASC base calculation and Arizona’s aggressive tiered rates, consider a hypothetical case study of AZ Tech Corp., a non-startup company that qualifies for the ASC election, with all QREs being Arizona-sourced.
Scenario Setup: AZ Tech Corp.
AZ Tech Corp. is calculating its 2024 Arizona R&D tax credit using the ASC method. The company’s QRE history over the preceding three years and the current year QREs are as follows:
Table Title: Hypothetical Arizona ASC Calculation Example (Current Year 2024)
| Metric | Data/Calculation Detail | Value |
| Prior QRE History (2021-2023) | ||
| Prior Year 3 (2021) QREs | Research expenses incurred in Arizona | $\$1,500,000$ |
| Prior Year 2 (2022) QREs | Research expenses incurred in Arizona | $\$2,500,000$ |
| Prior Year 1 (2023) QREs | Research expenses incurred in Arizona | $\$2,000,000$ |
| Current Year (2024) | ||
| Current Year (2024) QREs | Total Qualified Expenses in Arizona | $\$5,000,000$ |
| ASC Base Computation (Corresponding to Form 308-I, Part 12) | ||
| 1. Average QREs (Prior 3 Years) | $(\$1.5\text{M} + \$2.5\text{M} + \$2.0\text{M}) / 3$ | $\$2,000,000$ 5 |
| 2. ASC Base Amount (50% Lookback) | $50\% \times \$2,000,000$ (Line 1) | $\$1,000,000$ 5 |
| 3. Excess QREs (Incremental R&D) | Current Year QREs $(\$5.0\text{M}) – \text{ASC Base} (\$1.0\text{M})$ | $\$4,000,000$ 5 |
| Credit Application (AZ Tiered Rates) | ||
| 4. Tier 1 Credit Calculation | $24\% \times \$2,500,000$ (First $\$2.5\text{M}$ of Excess) | $\$600,000$ 1 |
| 5. Tier 2 Credit Calculation | $15\% \times (\$4,000,000 – \$2,500,000 = \$1,500,000)$ | $\$225,000$ 1 |
| 6. Total Arizona ASC Credit | Sum of Tier 1 and Tier 2 Credits | $$825,000 |
Comparative Analysis of the Financial Benefit
If AZ Tech Corp. were to calculate this credit using the federal ASC methodology, the credit would be $14\%$ of the excess QREs. The federal credit would equal: $\$4,000,000 \times 14\% = \$560,000$.5
By utilizing the Arizona tiered rate structure combined with the ASC base, the company achieves a credit of $\$825,000$, representing a substantial increase of $\$265,000$ over the federal rate calculation alone. This outcome clearly demonstrates the profound strategic value of the Arizona tiered rates when applied to the simplified ASC base.7
VIII. Compliance and Risk Mitigation: Substantiating the Claim
While the Alternative Simplified Credit method significantly reduces the administrative burden associated with calculating the historical base amount, it is imperative to understand that ASC election does not simplify or reduce the underlying documentation requirements necessary to substantiate the Qualified Research Expenses themselves.12 Both the IRS and the AZDOR will rigorously examine the eligibility of the claimed QREs.
Substantiating the Qualified Research Expenses (QREs)
The foundation of any successful R&D tax credit claim, regardless of the method used, rests on compliance with the federal Four-Part Test: permitted purpose, technological uncertainty, process of experimentation, and technological in nature.3 Failure to provide detailed documentation proving that the claimed expenses meet these criteria is the primary trigger for audit scrutiny.14
Key documentation elements necessary for robust audit defense include 13:
- Technical Justification Reports: Detailed narratives for each business component or project must clearly articulate the technological uncertainties encountered and the specific experimentation process undertaken to resolve them. This establishes the basis for credit eligibility.
- Project Logs: Contemporaneous records and project logs are necessary to detail the specific research activities performed.13
- Financial Allocation Records: Detailed timesheets and participation records for technical staff are critical for accurately allocating qualified wages to the specific R&D activities. This substantiation helps prevent the disallowance of claimed wages due to insufficient nexus to R&D or the inclusion of non-technical staff.13
- Financial Reconciliation: A comprehensive cost breakdown is required to reconcile the claimed qualified expenses (wages, supplies, 65% of contract research) back to the general ledger and the final tax filings.13 This also ensures unauthorized costs, such as overhead or indirect expenses, are excluded.
The Crucial State Nexus Requirement
The primary state-specific audit risk for the Arizona R&D tax credit involves the geographical allocation of QREs. Because Arizona statutes require that the qualified research be exclusively conducted in Arizona 8, AZDOR auditors will focus heavily on verifying the in-state nexus of the claimed expenses.
Taxpayers must maintain documentation that establishes the physical location where the research activities occurred. For instance, wage claims must be supported by employee location records, demonstrating that the technical staff performed their qualified services while physically present within the state. Contract research expenses must also be verified as performed by the contractor at an Arizona site.11 The analysis confirms that documentation must establish geographic nexus—proving where the work was performed—in addition to the standard technical substantiation required by the IRS.
Best Practices for Mitigation
To mitigate audit exposure, taxpayers should treat the ASC election as a simplification of calculation but not of compliance. Proactive measures include engaging specialized R&D tax consultants, performing internal “mock audits” to test documentation against the Four-Part Test and the Arizona geographical nexus requirement, and strictly adhering to all eligibility criteria, particularly the three-year QRE history required for the ASC method in Arizona.11
IX. Conclusion and Strategic Recommendations
Arizona’s adoption of the federal Alternative Simplified Credit (ASC) methodology, effective for tax years beginning in 2023, represents a significant enhancement to its already robust R&D tax incentive program. By adopting the simplified base calculation (50% of 3-year average QREs) while maintaining its aggressive tiered credit rates (24% up to $\$2.5$ million in excess QREs), the state has created a highly valuable, accessible, and scalable incentive for established companies with incremental R&D growth.
The ability to use the ASC streamlines compliance for companies with a stable history of research spending by removing the need for complex fixed-base percentage calculations involving historical gross receipts. However, the analysis reveals a critical difference from the federal framework: the prohibition on electing the Arizona ASC if the taxpayer had zero QREs in any of the three prior years compels true startups or first-time claimants to utilize the more documentation-intensive Regular Credit method.
Strategic Recommendations for Maximizing the Arizona ASC Benefit
Based on the statutory framework and regulatory guidance provided by AZDOR and the ACA, the following strategic recommendations are essential for maximizing the Arizona R&D tax credit:
- Validate Eligibility and Run Comparative Scenarios: Before election, taxpayers must rigorously confirm that Arizona QREs existed in all three preceding tax years. If not, the Regular Credit method is mandatory.11 Furthermore, taxpayers should calculate the credit under both the Regular and ASC methods to determine the maximum benefit, as the IRS itself suggests for the federal credit.12
- Plan Refundability Requirements in Advance: For businesses meeting the fewer-than-150-employee threshold, the refundable portion of the credit offers a crucial source of cash flow.10 The mandatory pre-approval process by the Arizona Commerce Authority (ACA) must be initiated well in advance of the tax filing deadline to ensure the required Certificate of Qualification is secured. The election for refundability must be designated on the original filed tax return.3
- Ensure Robust, Arizona-Specific Documentation: The ASC simplifies the calculation, but the need for technical substantiation remains paramount. Documentation must explicitly address the federal Four-Part Test and, critically, must prove the geographic nexus of all qualified expenses occurred entirely within Arizona state lines to withstand state audit scrutiny.8
Manage Contract Research Payments Carefully: When utilizing third-party research, remember that only 65% of contract research expenses are eligible, and they must be for research performed in Arizona.11 Payments to Arizona universities may qualify for an additional credit (Form 346), necessitating careful tracking and reporting.

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.
