Fixed-Base Percentage (Startups)

In the regulatory environment of North Dakota, the Fixed-Base Percentage for startups is a statutory ratio, typically initialized at three percent, used to establish a company’s historical research intensity for the purpose of calculating the base amount threshold. This metric acts as the primary benchmark that current-year research expenditures must exceed to generate a claimable income tax credit under the state’s regular research credit calculation method.

The implementation of the North Dakota Research and Experimental Expenditure Tax Credit, primarily governed by North Dakota Century Code (N.D.C.C.) § 57-38-30.5, represents a sophisticated effort by the state legislature to foster a high-technology economy within a region traditionally dominated by agriculture and energy extraction. While the state credit largely mirrors the federal Credit for Increasing Research Activities under Internal Revenue Code (IRC) § 41, it introduces specific nuances regarding the sourcing of expenses and the calculation of the Fixed-Base Percentage (FBP) that are critical for emerging enterprises to understand. For a startup, the FBP is not merely a static figure but a dynamic variable that evolves over a ten-year phase-in period, reflecting the company’s maturation from a pre-revenue venture to a stabilized market participant. This analysis explores the legal mechanisms, mathematical formulas, and administrative guidance provided by the North Dakota Office of State Tax Commissioner and the Department of Commerce to provide a comprehensive guide for professional practitioners and business leaders.

The Legislative Foundation of N.D.C.C. § 57-38-30.5

The North Dakota research tax credit was established to incentivize businesses to invest in qualified research activities (QRAs) within the state’s geographic boundaries. The state’s reliance on federal definitions creates a streamlined compliance environment for taxpayers who are already claiming the federal R&D credit, yet the state-specific limitations regarding North Dakota-sourced expenses and the tiered rate structure necessitate a distinct internal accounting approach.

Convergence with Federal Standards

Under the North Dakota Century Code, the terms “qualified research expenses” (QREs) and “base amount” are explicitly tied to the definitions provided in IRC § 41. This alignment ensures that the “Four-Part Test” used by the Internal Revenue Service (IRS) is also the standard for North Dakota state audits. To qualify, an activity must meet the following criteria:

• The research must be intended to discover information that is technological in nature, relying on principles of physical or biological science, engineering, or computer science.
• The purpose of the research must be to develop a new or improved business component, such as a product, process, software, technique, or formula.
• The activity must seek to eliminate technical uncertainty regarding the capability, method, or optimal design of the business component.
• Substantially all of the activities must constitute a process of experimentation, involving the evaluation of alternatives through modeling, simulation, or systematic trial and error.

Despite this federal convergence, North Dakota law imposes a strict geographic nexus. Only research conducted within North Dakota and expenses attributable to North Dakota activity are eligible for the credit. This distinction is vital for startups that may have remote developers or out-of-state contractors; while those costs might count toward the federal credit, they are excluded from the North Dakota calculation.

The Evolution of Credit Rates and Caps

The North Dakota credit has undergone several legislative revisions to its rate structure. Currently, for most modern taxpayers—specifically those who began research in North Dakota after December 31, 2006—the credit is calculated based on “excess” research expenses. Excess is defined as the current year’s QREs minus the base amount.

Tier of Excess QREs	Current Credit Rate
First $100,000	25.0%
Amounts exceeding $100,000	8.0%

This tiered structure is highly favorable for startups. A company with $100,000 in excess QREs generates a $25,000 tax credit, representing a substantial 25% subsidy on their incremental investment. Historically, different rates applied; for example, between 2007 and 2016, the second-tier rate for certain taxpayers was as high as 20%, but it was later adjusted to 8% to manage the state’s fiscal liability. Taxpayers who earned credits prior to 2007 face a $2 million annual cap and no carryover provisions, whereas modern startups enjoy a lack of annual caps and extensive carryforward rights.

Mathematical Modeling of the Fixed-Base Percentage

The Regular Research Credit (RRC) method relies on the relationship between a firm’s current research spending and its historical research intensity. The Fixed-Base Percentage (FBP) is the mathematical expression of this historical intensity.

The Base Amount Calculation

The FBP is utilized to determine the “base amount,” which serves as the threshold for the credit. The formula is as follows:

Base Amount = Fixed-Base Percentage × Average Annual Gross Receipts (Prior 4 Years)

This calculation ensures that the credit is truly “incremental,” rewarding companies only when their current research spending exceeds their historical average relative to their revenue. However, the law includes a safeguard known as the “Minimum Base Amount.” Under IRC § 41(c)(2), the base amount can never be less than 50% of the current year’s QREs. For high-growth startups with minimal historical revenue, this 50% floor is often the determining factor in their credit calculation, effectively capping the marginal credit rate.

The Startup Definition and the Phase-In Schedule

For the purpose of the FBP, a “startup” is defined by the timing of its research and revenue history rather than its date of incorporation. A taxpayer is classified as a startup if it had both gross receipts and QREs for the first time in a taxable year beginning after December 31, 1983, or if it had fewer than three such years between 1984 and 1988.

Recognizing that new companies often have volatile spending and revenue patterns, the tax code provides a ten-year phase-in for the FBP. This prevents a startup from being locked into a high intensity ratio based on a single year of high R&D and low sales.

Year of Research Activity	Fixed-Base Percentage (FBP) Calculation
Years 1 through 5	3.00%
Year 6	1/6 of (Aggregate QREs for Years 4–5 ÷ Aggregate Gross Receipts for Years 4–5)
Year 7	1/3 of (Aggregate QREs for Years 5–6 ÷ Aggregate Gross Receipts for Years 5–6)
Year 8	1/2 of (Aggregate QREs for Years 5–7 ÷ Aggregate Gross Receipts for Years 5–7)
Year 9	2/3 of (Aggregate QREs for Years 5–8 ÷ Aggregate Gross Receipts for Years 5–8)
Year 10	5/6 of (Aggregate QREs for Years 5–9 ÷ Aggregate Gross Receipts for Years 5–9)
Year 11 and beyond	The actual ratio of QREs to Gross Receipts for any 5 years between Years 5 and 10

This progression allows the FBP to gradually trend toward the company’s actual long-term average. During the first five years, the 3% FBP is often much lower than a tech startup’s actual intensity, which may be 20% or 50% of revenue. This creates a low base amount and a high volume of “excess” research expenses, maximizing the 25% and 8% credits.

Local State Revenue Office Guidance on Compliance

The North Dakota Office of State Tax Commissioner provides essential administrative guidance on how these laws are applied in practice, particularly regarding the determination of “gross receipts” and the conduct of audits.

Defining North Dakota Gross Receipts

For the purposes of the North Dakota R&D credit, “gross receipts” must be attributable to North Dakota activity. This typically involves sourcing revenue based on the location of the customer or where the service is delivered, following the state’s standard apportionment rules. Revenue figures must be reported net of returns and allowances.

Guidance from the Tax Commissioner emphasizes that if a company has zero gross receipts in North Dakota for any of the four prior years—which is common for early-stage software or biotech startups—the base amount will likely be dictated by the 50% minimum base rule. Startups must meticulously track their North Dakota revenue to ensure they do not overstate the FBP in later years, which would lead to an artificially high base amount and a lower credit.

Audit Windows and Record Retention

Taxpayers must be aware of the North Dakota-specific statute of limitations for tax assessments. The Tax Commissioner generally has three years from the date a return is filed or the due date (whichever is later) to conduct an audit. However, this window expands to six years if there is a “substantial change” in taxable income or liability exceeding 25% of the amount stated on the return. In instances of fraud or willful evasion, there is no time limit for assessment.

Professional guidance suggests that startups should retain project records for at least four to six years. Documentation must be sufficient to substantiate that the expenses were incurred for qualified research and that they were sourced correctly to North Dakota. The Commissioner requires “consistency” in reporting; if a startup changes how it classifies certain software developer wages as QREs, it must apply that same logic to its base period calculations to ensure a valid comparison.

Certification for Research and Development Companies

One of the most distinctive features of the North Dakota R&D landscape is the ability for startups to monetize their credits even if they are not yet profitable. This is achieved through the certification of “Qualified Research and Development Companies”.

Eligibility for Credit Transfer

Under N.D.C.C. § 57-38-30.5(9), a taxpayer may elect to sell, transfer, or assign all or part of their unused tax credit if they are certified by the Director of the Department of Commerce. This certification is reserved for companies that meet the following criteria:

• The business must be a certified “primary sector business.” This means it adds value to a product or process through labor or knowledge, creating new wealth for the state.
• The company must have annual gross revenues of less than $750,000.
• The business must not have conducted new research and development in North Dakota prior to specific dates (generally after 2006 for some provisions and after 2016 for others).
• The transferor must be an individual, C corporation, estate, or trust. Passthrough entities like S corporations and partnerships are ineligible to sell the credit at the entity level.

Procedural Requirements for Transfers

A qualified startup may transfer up to a lifetime total of $100,000 in credits. To execute a transfer, the startup and the purchasing taxpayer must jointly file Form CTS (Credit Transfer Statement) with the Tax Commissioner within 30 days of the purchase agreement. The agreement must disclose the purchase price, and the gross proceeds received by the transferor are assigned to North Dakota, meaning they cannot be reduced by net operating losses or other state-level deductions.

This mechanism provides a critical cash infusion for pre-revenue startups, effectively allowing them to trade future tax offsets for immediate working capital. For example, a software startup in Fargo might sell $50,000 of credits to a profitable manufacturing firm in Bismarck for $40,000 (80 cents on the dollar), providing liquidity to hire additional engineers.

Detailed Example: Calculating the Startup Credit

To demonstrate the application of the Fixed-Base Percentage and the tiered rates, consider “AgroTech Solutions,” a North Dakota-based startup specializing in autonomous irrigation sensors.

Financial Profile of AgroTech Solutions

AgroTech is in its fourth year of operation (Year 4 of research). It is currently a pre-revenue company.

• Current Year (Year 4) QREs: $150,000 (All North Dakota-sourced).
• Prior 4 Years Gross Receipts: $0 (Pre-revenue).
• Average Annual Gross Receipts (AAGR): $0.

Step 1: Establish the Fixed-Base Percentage (FBP)

Since AgroTech is in its first five years of research activity, it utilizes the statutory startup FBP of 3.00%.

Step 2: Determine the Base Amount

The calculated base amount is the product of the FBP and the AAGR:

Base Amount = 0.03 × $0 = $0

However, the 50% minimum base rule must be applied:

Minimum Base Amount = 0.50 × $150,000 = $75,000

Because the minimum base ($75,000) is greater than the calculated base ($0), the effective Base Amount is $75,000.

Step 3: Calculate Excess QREs

The excess is the amount of current spending that surpasses the base amount threshold:

Excess QREs = $150,000 – $75,000 = $75,000

Step 4: Apply Tiered Credit Rates

The North Dakota credit rate is 25% for the first $100,000 of excess.

Credit Amount = $75,000 × 0.25 = $18,750

AgroTech Solutions has generated a $18,750 tax credit. Because they are pre-revenue and have no tax liability, they can either carry this credit forward for 15 years or, if they obtain primary sector certification and have revenues under $750,000, they can sell the credit to another taxpayer for cash.

Statistical Insights into the North Dakota R&D Environment

The impact of the research tax credit on North Dakota’s economy is documented through various state studies and fiscal reports. These statistics provide context for the importance of the incentive to the state’s growth strategy.

Economic and Fiscal Impact Data

A 2021 study commissioned by the Taxation Committee revealed several key findings regarding the incentive’s performance between 2007 and 2016:

• Participation: Approximately 1,800 unique taxpayers claimed the credit during this ten-year period.
• Taxpayer Profile: In 2016, individual taxpayers (representing owners of passthrough entities) claimed over $4.5 million in credits, while C corporations claimed over $500,000. This indicates that the credit is heavily utilized by smaller, entrepreneur-led businesses.
• Job Creation: The credit was estimated to have contributed to the addition of 1,100 jobs to the state.
• GDP Contribution: The annual impact on North Dakota’s Gross Domestic Product was estimated at $80 million.

Fiscal Metric (20-Year Projection)	Value
Projected State Revenue Increase	$213 Million
Direct Fiscal Cost to General Fund	$66 Million
Indirect Costs	$182 Million
Net Budgetary Impact	($30 Million Liability)

The study noted that while the credit is a net liability to the state budget, it is considered a success due to its “positive impact on the state’s economy” and its role in supporting diverse sectors like agriculture and energy.

Sector-Specific Adoption

The credit has seen meaningful usage in North Dakota’s core “primary sectors.” Basin Electric Power Cooperative, for instance, reported over 500 employees allocated to research activities and accumulated over $10 million in credits over a three-year span. For startups in the agricultural sector, the credit frequently supports the development of new process enhancements or the prototyping of specialized machinery.

Alternative Simplified Computation (ASC) Method

While the Regular Method (with its FBP) is the traditional approach, North Dakota’s adoption of the Alternative Simplified Method in 2019 provides an important alternative for startups.

Mechanism of the ASC

The ASC method does not require historical gross receipts or the calculation of a Fixed-Base Percentage. Instead, it uses the company’s QRE history from the three preceding years. The North Dakota ASC rates are as follows:

• 17.5% for the first $100,000 of “North Dakota alternative excess” expenses.
• 5.6% for amounts over $100,000.

“Alternative excess” is defined as the current-year QREs minus 50% of the average QREs for the prior three years.

Comparison for Startups

For a startup with no research history, the ASC defaults to a flat rate:

• 7.5% of the first $100,000 of QREs.
• 2.4% of QREs over $100,000.

Comparison Point	Regular Method (FBP)	ASC Method (No History)
First $100k Rate	25% of Excess	7.5% of Total
Threshold	Base Amount (Minimum 50% QRE)	$0 (in first year)
Monetization	Transferable (if qualified)	Transferable (if qualified)

For a startup in its first year with $100,000 in QREs, the Regular Method would yield a $12,500 credit (25% of the $50,000 excess), whereas the ASC would yield a $7,500 credit. Consequently, the Regular Method—and its reliance on the 3% FBP—remains the more lucrative path for most high-intensity startups in their early years.

Practical Guidance for Business Owners and CPAs

To successfully claim and defend the North Dakota R&D credit, companies must move beyond the mathematical formulas and engage in robust administrative practices.

Integrated Tax Planning

Startups should consider the R&D credit as part of a comprehensive tax strategy that includes other state incentives, such as the Automation Tax Credit or the Internship Employment Credit. The Automation Tax Credit, which provides up to 15% of the cost of manufacturing or animal agricultural machinery, can sometimes overlap with R&D activities if the equipment is used for prototyping new processes.

Furthermore, because North Dakota allows the credit to be carried back three years, a startup that becomes profitable in its fifth year can retroactively claim credits from its second year, resulting in an immediate refund of taxes paid. This carryback must be filed within three years of the due date for the return in which the credit was earned.

Sourcing and Documentation Challenges

A common error in North Dakota R&D claims involves the misallocation of “Contract Research” expenses. Under state law, payments to third parties for research are typically includable at 65% of the actual cost, but the research must be performed in North Dakota. If a Bismarck startup hires a development firm in Minneapolis, those expenses are disqualified for the North Dakota credit, even if they qualify for the federal credit.

Documentation must also clearly distinguish between “Qualified Research” and “Non-Qualifying Activities.” Activities that are excluded from the credit include:

• Research conducted after the start of commercial production.
• The adaptation of an existing business component to a particular customer’s requirement.
• Reverse engineering.
• Market research, sales promotion, or routine quality control.
• Research related to social sciences, arts, or humanities.

Maintaining project-based time tracking for employees is the gold standard for surviving an audit by the Tax Commissioner.

Final Thoughts: The Strategic Value of the Fixed-Base Percentage

The Fixed-Base Percentage is far more than a variable in a tax equation; it is the mechanism by which North Dakota differentiates between routine business activity and genuine, incremental innovation. For the startup community, the statutory 3% FBP provides an intentional advantage, lowering the barriers to entry for companies that are heavy on ideas but light on revenue. This policy choice reflects a deliberate state effort to subsidize the high-risk, high-reward phase of technological development.

By combining the low FBP threshold with a generous 25% initial credit rate and the ability to sell unused credits for cash, North Dakota has created a fiscal environment tailored for the modern entrepreneur. However, the complexity of the ten-year phase-in and the geographic sourcing requirements necessitates a disciplined approach to accounting and documentation. As startups mature and their Fixed-Base Percentage begins to reflect their actual operational history, the credit transition from a “volume-based” incentive to a strictly “incremental” one, pushing firms to continuously increase their commitment to research and development within the state. For professional peers and business leaders, mastering the nuances of the FBP is essential for optimizing capital efficiency and securing the full economic benefits of North Dakota’s investment in its own technological future.
