Expert-Level Report: Analyzing the Alternative Simplified Credit (ASC) Method within the Delaware R&D Tax Credit Framework

The Alternative Simplified Credit (ASC) is an elective federal method (IRC § 41(c)(5)) calculated as 14% of current-year Qualified Research Expenses (QREs) exceeding 50% of the average QREs from the three prior years.

In Delaware, the ASC serves as a foundation for an elective credit (Method B under 30 Del. C. § 2070) that can deliver a fully refundable incentive equal to 50% (or 100% for small businesses) of the appropriately apportioned federal ASC amount.

This report provides a detailed examination of the ASC method, its precise integration into Delaware law, the resulting strategic opportunities for businesses, and the compliance requirements established by the Delaware Division of Revenue.

Part I: The Federal Foundation—Understanding the Alternative Simplified Credit (ASC)

1.0 IRC Section 41 and the Federal R&D Tax Credit Mandate

The federal framework for the Research and Development (R&D) tax credit, governed by Internal Revenue Code (IRC) Section 41, is the essential prerequisite for claiming the corresponding credit in Delaware. For a research activity to qualify for the Delaware credit, it must first satisfy the definition of a Qualified Research Activity (QRA) under federal law, typically requiring the activity to pass the “four-part test” (e.g., must be experimental in nature, intended to eliminate technological uncertainty, and relate to a permitted purpose).1

Delaware’s statute, 30 Del. C. § 2070, implicitly adopts the federal definitions for Qualified Research Expenses (QREs). QREs generally fall into three categories defined federally: wages paid to employees performing, supervising, or directly supporting qualified research; the cost of supplies consumed in the research process; and 65% of contract research expenses paid to unrelated third parties for qualified services.1 Therefore, meticulous documentation adhering to federal substantiation requirements is mandatory, as any expense that fails the federal test is automatically disqualified for the Delaware credit.

1.1 Comparison of Calculation Methods: RRC vs. ASC

The complex nature of calculating the federal R&D tax credit has led the U.S. government to offer taxpayers two distinct methods: the Regular Research Credit (RRC) and the Alternative Simplified Credit (ASC).

The Regulatory Imperative for Simplification

The Regular Research Credit (RRC) is often administratively burdensome, particularly because it relies on the calculation of a historical Fixed Base Percentage (FBP). The FBP is derived from a taxpayer’s QREs and gross receipts from the four years spanning 1984 through 1988.2 For companies that have experienced significant growth since that base period, or for firms that lack the historical records necessary to document their base amount, the RRC method can be highly challenging to use or may yield a negligible credit.3 Taxpayers who experience high growth in gross receipts alongside flat research expenditures may find themselves ineligible for the RRC because their current year QREs do not exceed the historical base amount.2

The Strategic Value of ASC

The ASC method (IRC § 41(c)(5)) was introduced to address these complexities, offering a streamlined, accessible alternative.4 Unlike the RRC, the ASC method eliminates the requirement to calculate and document the historical FBP and does not require gross receipts as a component of the calculation formula.3 Instead, it relies solely on the QREs incurred over the three immediately preceding tax years.3

For many businesses, especially smaller companies or startups that may lack legacy records, the ASC provides a pathway to eligibility that the RRC may deny.4 Furthermore, when a taxpayer’s QREs are steadily increasing year-over-year, the ASC often provides a more favorable result than the RRC, given the fixed 14% rate applied to the incremental increase over the relatively low 50% base.2

Table 1.1: Federal R&D Calculation Method Comparison: RRC vs. ASC

1.2 The Mechanics of Federal ASC Calculation (IRC § 41(c)(5))

The computation of the federal ASC is governed by Treasury Regulation § 1.41-9.5 The formula is designed to calculate a credit based on the current year’s incremental increase in research spending relative to a moving average base.

Formula Breakdown: 14% Over 50% Lookback

The calculation process follows four distinct steps 3:

1. Calculate the Average Prior QREs: Determine and sum the Qualified Research Expenses incurred in the three immediately preceding tax years, then compute the average QREs for that three-year period.
2. Establish the Base Amount: Multiply the average QREs from step 1 by 50%.3 This establishes the minimum research expenditure threshold that must be exceeded in the current year to generate a credit.
3. Determine Incremental QREs: Subtract the base amount (50% of the three-year average) from the current year’s QREs.6
4. Calculate the Credit: Apply a credit rate of 14% to the resulting amount (the incremental QREs) to determine the R&D tax credit.3

Rule for New Filers (6% Floor)

In scenarios where the taxpayer is newly engaged in research or otherwise had no QREs during any of the three prior years, the formula is further simplified. In this case, the credit is calculated as 6% of the QREs in the current tax year.3 This 6% floor ensures that even new R&D entities or startups without an established history can immediately qualify for the incentive.

Election Rules and Consistency

The election to use the ASC at the federal level must be made on an original return and is generally binding for subsequent years unless formally revoked.2 This necessitates careful long-term planning before making the initial election.

Furthermore, consistency is paramount. IRC § 41(f) requires consistency in determining QREs across all years used in the calculation (the credit year and the base years).2 The integrity of the ASC calculation, both federally and by extension in Delaware, hinges on the consistency and proper documentation of these expenditures. If a federal audit challenges the proper inclusion of expenses or the consistent application of QRE definitions in the base years, this adjustment directly reduces the total federal ASC. Because the Delaware credit (Method B) uses the calculated federal ASC as its primary input, any reduction in the federal credit amount directly diminishes the base available for the state credit.

Part II: Integration with Delaware Law (30 Del. C. § 2070)

The State of Delaware offers a highly attractive R&D incentive authorized under Delaware Code Annotated, Title 30, Chapter 20, Subchapter VIII, specifically § 2070.1 This state credit is strategically compelling due to its full refundability and its direct, favorable linkage to the federal ASC calculation.

2.1 Delaware’s Statutory Dual-Track Election System

Delaware allows taxpayers to choose between two methods for calculating their state R&D credit, providing necessary flexibility for optimization. Crucially, 30 Del. C. § 2070 specifies that the taxpayer’s Delaware R&D tax credit determination election shall be an annual election and shall be independent of the taxpayer’s federal R&D tax credit determination.7 This policy is vital: a business may calculate its credit using the RRC federally but find that Delaware’s Method B (ASC Linkage) yields a higher benefit at the state level, requiring a comparative analysis annually.

The two elective methods are:

• Method A (Traditional/Incremental): The credit is equal to 10% (or 20% for qualifying small businesses) of the excess of the taxpayer’s total Delaware QREs for the taxable year over the taxpayer’s Delaware base amount.1
• Method B (ASC Linkage): The credit is equal to a percentage (50% or 100% for small businesses) of Delaware’s apportioned share of the taxpayer’s federal R&D tax credit, calculated using the Alternative Simplified Credit method under IRC § 41(c)(5).1

2.2 Detailed Analysis of the ASC Linkage (Method B)

Method B provides a direct mechanism for taxpayers to leverage their federal ASC calculation to claim a state credit.

Standard Rate and Apportionment

For businesses whose average annual gross receipts exceed the small business threshold of $20 million, the standard Delaware rate under Method B is 50% of Delaware’s apportioned share of the federal ASC.1

The apportionment step is mandatory for any taxpayer that conducts research activities both inside and outside of Delaware. Apportionment ensures that only the portion of the federally calculated credit attributable to research activities physically conducted within the state’s borders is claimed.

The statute defines Delaware’s apportioned share of the federal credit as the amount of the federal ASC (calculated using IRC $\S 41(\text{c})(5)$ methodology) multiplied by a specific ratio 7:

$$\text{Delaware Apportioned Credit} = \text{Federal ASC} \times \frac{\text{Delaware Qualified Research Expenses}}{\text{Total Qualified Research Expenses}}$$

This mechanism requires taxpayers to meticulously track and document QREs based on their geographic location. Taxpayers must ensure that the QREs used in the numerator of this ratio (Delaware QREs) are supported by detailed, location-specific substantiation of wages paid, supplies consumed, and contract research performed within the state.1

2.3 Small Business Enhancement: The 100% ASC Credit

Delaware provides a significant enhancement to its R&D credit to incentivize smaller, high-growth companies.

Statutory Definition of a Small Business

For the purposes of the R&D credit, a “small business” is defined as any taxpayer with average annual gross receipts, determined by the methodology in IRC § 41(c)(1)(B), not in excess of the applicable threshold of $20,000,000.7 This definition ensures that the state benefit is targeted toward early-stage and mid-sized firms.

The Enhanced Rate (100% Multiplier)

Qualifying small businesses are subject to a significantly more generous calculation under Method B: they receive 100% of Delaware’s apportioned share of the federal research credit calculated using the ASC method.1

This aggressive 100% multiplier means that Delaware’s incentive for small businesses is exceptionally competitive. Considering that the federal ASC formula yields 14% of incremental QREs, allowing a small business to claim 100% of the apportioned federal ASC effectively means that the state provides an equivalent of 14% of the incremental QREs incurred in Delaware. This generous rate, especially when coupled with the fully refundable nature of the Delaware credit (discussed in Part III), offers immediate, non-dilutive working capital (cash) to R&D-intensive startups and growth companies, which significantly enhances Delaware’s status as a hub for innovation.10

Table 2.3: Delaware R&D Credit Calculation Summary (30 Del. C. § 2070)

Part III: Delaware Division of Revenue Guidance and Compliance

The administration of the Delaware R&D tax credit falls under the jurisdiction of the Delaware Division of Revenue.1 Claiming the credit requires strict adherence to state procedures, forms, and filing deadlines.

3.1 Administrative Authority and Key Forms

The credit is not claimed directly on the state income tax return; instead, it requires an annual application for approval. Taxpayers must submit Form 2070AC, the “Application and Computation Schedule for Claiming Delaware Research and Development Tax Credits”.1

A critical compliance requirement is the mandate to attach a copy of the federal research credit Form 6765 to the state application.12 This requirement ensures the Delaware Division of Revenue can verify the foundational federal ASC calculation used as the base for the state credit calculation under Method B before applying the apportionment ratio.

3.2 Filing Requirements, Deadlines, and Credit Characteristics

Mandatory Deadline and Compliance Risk

The application for the R&D credit must be submitted to the Division of Revenue by September 15th following the end of the taxable year during which the qualified R&D expenses were incurred.1

This deadline is absolute and represents a significant compliance concern for corporate tax departments. Many taxpayers routinely extend the filing of their federal and state income tax returns, often to October 15th. However, the September 15th deadline for Form 2070AC is non-extensible for the credit application itself. Failure to complete the complex R&D credit study, compile the documentation, and file the Form 2070AC by September 15th will result in the forfeiture of the credit for that taxable year. Tax teams must treat the Form 2070AC filing as a high-priority, non-extensible task, regardless of extensions granted for the primary corporate income tax returns.

Refundability and Pass-Through Entities

One of the most significant advantages of the Delaware R&D credit is its fully refundable nature.1 If the approved tax credit exceeds the taxpayer’s corporate income tax liability, the unused credits are paid to the taxpayer as a direct cash refund.1 This feature makes the Delaware incentive especially attractive, as it provides immediate liquidity rather than merely creating a tax asset in the form of carryforwards.

For pass-through entities such as S corporations and partnerships, the Delaware Division of Revenue provides specific instructions for credit allocation.14 The approved Delaware R&D Credit is multiplied by the percentage of stock owned by each shareholder (for S corporations) or the percentage ownership of each partner (for partnerships). The resulting allocated credit amounts are then entered onto the Delaware Income Tax Credit Schedule (Form 700).14

3.3 The Annual Credit Cap and Proration Rules

While the credit is generous and refundable, Delaware places a limitation on the total amount of R&D credits awarded statewide in any given fiscal year. The state imposes an annual cap of $5,000,000 in total credits across all applicants.12

Statutory Proration Formula

Should the aggregate amount of research and development tax credits applied for by all eligible taxpayers in any fiscal year exceed the statutory cap of $5,000,000, the Delaware Division of Revenue is mandated to prorate the available credits. The amount each applicant ultimately receives is determined by the following statutory formula 14:

$$\text{Credit Received} = \$5,000,000 \times \frac{\text{Applicant’s Eligible R\&D Tax Credit Applied For}}{\text{Total of All Eligible R\&D Tax Credits Applied For}}$$

This cap introduces a layer of financial uncertainty for taxpayers, particularly those making large credit claims or filing during years of high statewide R&D investment activity. While the refundable nature of the credit is highly beneficial, the cap serves to protect the state’s fiscal position by limiting the total cash outflow.16 Taxpayers must factor in the potential for proration when projecting the final cash benefit from the Delaware R&D credit.

Part IV: Computational Modeling: A Detailed Delaware ASC Example

To illustrate the strategic advantage and mechanical process of the ASC Linkage Method (Method B) in Delaware, consider the following scenario involving a small business.

4.1 Scenario Setup: TechCorp DE (Small Business)

TechCorp DE, a multi-state technology company, qualifies as a Small Business because its average annual gross receipts are $15,000,000 (below the $20,000,000 threshold). TechCorp elects Method B (100% ASC Linkage) for Tax Year (TY) 2024.

4.2 Step-by-Step Federal ASC Calculation (IRC § 41(c)(5))

This calculation determines the baseline federal ASC amount using national (Total) QREs.

1. Calculate 3-Year Average QREs (2021-2023):

• $(\$400,000 + \$500,000 + \$600,000) / 3 = \$1,500,000 / 3 = \$500,000$

1. Determine Federal ASC Base Amount (50%):

• $\$500,000 \times 50\% = \$250,000$

1. Determine Incremental QREs (Amount exceeding the base):

• $\$1,200,000 (\text{CY QREs}) – \$250,000 (\text{Base}) = \$950,000$

1. Calculate Gross Federal ASC (14%):

• $\$950,000 \times 14\% = \mathbf{\$133,000}$

4.3 Step-by-Step Delaware ASC Apportionment and Credit Calculation

The calculated Federal ASC of $133,000 is now localized to Delaware activity.

1. Calculate Delaware QRE Apportionment Ratio:

• This ratio compares QREs incurred within Delaware to the total QREs nationwide.8
• $\$900,000 (\text{Delaware QREs}) / \$1,200,000 (\text{Total QREs}) = \mathbf{75.0\%}$

1. Determine Delaware’s Apportioned Share of Federal ASC:

• $\$133,000 (\text{Federal ASC}) \times 75.0\% (\text{Ratio}) = \mathbf{\$99,750}$

1. Calculate Final Delaware R&D Tax Credit (Small Business Rate):

• Since TechCorp DE is a small business, the multiplier is 100%.1
• $\$99,750 (\text{Apportioned Share}) \times 100\% (\text{Multiplier}) = \mathbf{\$99,750}$

The final approved credit amount for TechCorp DE in TY 2024 is $99,750, which is fully refundable, subject only to the annual state cap and proration rules.

Conclusion: Strategic Considerations and Maximizing the Delaware Incentive

The Alternative Simplified Credit methodology provides a crucial, streamlined pathway for Delaware taxpayers seeking substantial R&D incentives. The state’s statute, 30 Del. C. § 2070, successfully leverages the administrative simplicity of the federal ASC while adding powerful state-level enhancements, notably full refundability and preferential rates for small businesses.

Strategic Recommendations for Taxpayers

The analysis of the Delaware R&D credit framework reveals several key strategic considerations necessary for tax optimization and compliance certainty:

Independent Annual Election is Mandatory

The statutory provision allowing an annual election independent of the federal method provides essential flexibility. Taxpayers should never assume that their federal R&D calculation method (RRC or ASC) automatically yields the optimal state credit. Modeling must be performed every year to compare the potential outcome of Delaware Method A (excess QREs) versus Method B (ASC linkage), ensuring the business selects the mechanism that maximizes the state benefit.8

Prioritize Cash Flow via Refundability

The fully refundable nature of the Delaware credit is a defining competitive advantage compared to incentives offered by many other states.11 This characteristic converts tax benefits directly into cash flow, which is highly advantageous for R&D-intensive companies that may experience tax losses or have low corporate income tax liabilities during periods of heavy investment.13 Taxpayers must correctly use Form 700 to allocate these credits to ensure the proper refund mechanism is triggered.14

Compliance Management: The September 15th Deadline

The September 15th deadline for filing Form 2070AC is non-negotiable and requires rigorous adherence.12 Compliance teams must integrate this date into their annual tax calendar and ensure that the underlying federal R&D study (including the required Form 6765) is completed in time to support the state application. Failure to meet this single deadline results in the complete loss of the state credit for the tax year in question.

Rigorous Apportionment Documentation

For multi-state companies, the apportionment calculation—multiplying the federal ASC by the ratio of Delaware QREs to Total QREs—demands meticulous, contemporary documentation.8 This necessitates maintaining real-time, state-by-state records to substantiate that QREs (wages, supplies, and contract research) included in the numerator were physically incurred within Delaware’s borders and meet the federal standards of qualified research.1

Assessing Risk from the State Cap

While the credit is robust, taxpayers must be mindful of the $5 million annual aggregate cap.14 Although proration is often viewed as a lower probability event, large R&D spenders, particularly those claiming the enhanced small business rate, must factor this potential uncertainty into their financial modeling and risk mitigation planning when anticipating the final cash benefit from the credit.
