Non-Refundable Credit: Defined
A non-refundable credit can reduce a company's tax liability to zero, but no further. Unlike refundable credits, any excess amount is not paid out as cash to the taxpayer, though it may often be carried forward to future years.
The Mechanics of Limitation
In the context of the Alaska R&D Tax Credit, the "non-refundable" status is the primary governing constraint on the credit's immediate value. While the federal government and some states offer refundable portions for small businesses or startups, Alaska's credit focuses on offsetting existing corporate income tax liability (AS 43.20.021).
This creates a specific financial dynamic: Profitability is a prerequisite for utilization. A company spending millions on R&D in Alaska without a corresponding net income tax bill will generate credits that sit on the balance sheet rather than generating immediate cash flow.

- 0 $0 Floor: Tax liability cannot go below zero.
- 7 7-Year Carryforward: (Typical). Unused credits are not lost immediately but expire if income remains low.

Department of Revenue Guidance
The Alaska Department of Revenue (DOR) strictly interprets the interaction between credits and liability. The application of the law follows a specific hierarchy of claims against the tax due.
- Current year non-refundable credits.
- Carryforward non-refundable credits (FIFO basis).
- Refundable credits (applied last to maximize cash refund potential).
Since R&D is non-refundable in Alaska, it must be exhausted against liability before determining final payment.

Pro Tip
A common error is assuming federal R&D rules (IRC 41) automatically make the state credit refundable. Alaska adopts the definition of expenses from the IRC, but not the payment mechanism.
Strategic Implications & Conclusion
For businesses operating in Alaska, the non-refundable nature of the R&D credit dictates that tax planning must align research expenditures with projected income windows.
Credit Portfolio Allocation

1. Income Forecasting
Companies must forecast taxable income 3-5 years out. If a net loss is projected, R&D credits will merely stockpile.
2. M&A Considerations
In mergers, the value of carried-forward non-refundable credits may be discounted significantly if the acquiring entity cannot utilize them immediately due to ownership change limitations.
3. Compliance Cost vs. Benefit
Calculating the R&D credit is administratively heavy. If the credit is non-refundable and likely to expire, the ROI on the accounting cost decreases.
Conclusion
The Alaska R&D tax credit is a powerful incentive, but its non-refundable nature requires it to be viewed as a tax reduction tool, not a grant. Businesses must demonstrate tax liability to unlock the cash value of their innovation. Without liability, the credit remains a theoretical asset on the books, subject to carryforward limitations.
The Strategic Imperative of Non-Refundable Credits in the Alaska R&D Tax Program
I. Executive Summary: The Mechanism and Strategic Value of Alaska’s R&D Credit
A non-refundable tax credit is a dollar-for-dollar reduction of tax liability that is strictly capped by the total tax owed, meaning it can reduce a tax bill to zero but can never result in a cash refund for any excess amount.1 The Alaska R&D Tax Credit (AS 43.20.021) leverages this structure as a non-refundable corporate incentive, providing robust longevity for innovation expenditures through a beneficial 1-year carryback and 20-year carryforward period, ensuring long-term monetization.3
Detailed Contextual Overview: The Alaskan Incentive Landscape
The State of Alaska maintains its Research and Development (R&D) tax credit program to strategically encourage in-state innovation and technological development.3 This program provides a powerful state incentive that is fundamentally tethered to the analogous federal R&D tax credit (Internal Revenue Code Section 41). The Alaska credit is specifically calculated as 18% of the federal R&D credit amount that is attributable to the state.4
For businesses, the credit serves as a critical mechanism to reduce the high marginal tax burden imposed by the Alaska corporate income tax.3 However, its designation as a non-refundable credit significantly influences corporate tax strategy. Since the credit cannot generate cash flow directly in the current year, its utility is limited by current profitability and tax liability.6 This constraint necessitates that corporations treat the credit not merely as a temporary discount but as a long-term deferred tax asset, demanding sophisticated tax planning focused on maximizing utilization over the subsequent two decades.
II. Fundamentals of Credit Classification: Non-Refundable vs. Refundable
Understanding the strict categorization of the Alaska R&D credit requires a foundational grasp of the distinction between refundable and non-refundable tax attributes. This differentiation dictates both the immediate financial impact and the long-term planning obligations for the taxpayer.
The Definitive Line: Tax Liability Reduction vs. Direct Refund Generation
The primary function of a non-refundable tax credit is to serve as an offset against a taxpayer’s calculated tax liability. Critically, this function has a ceiling: the total tax liability.2 Non-refundable credits can reduce the amount of tax payable down to zero, but any portion of the credit that exceeds the original liability is rendered unusable in that tax year for immediate financial benefit.1 For instance, if a corporation determines its total tax due is $200, but qualifies for a $350 non-refundable credit, the corporation will utilize only $200 of that credit, resulting in a $0 tax bill. The remaining $150 credit is not returned to the taxpayer as a cash payment but must instead be carried over to future tax years.1
This mechanism stands in sharp contrast to refundable tax credits. Refundable credits, such as the federal Earned Income Tax Credit (EITC), are designed to provide a benefit even when the tax liability has already reached zero.7 If a refundable credit exceeds the calculated tax bill, the difference is paid out directly to the taxpayer, effectively generating a cash refund.7 This direct cash benefit makes refundable credits a crucial tool for immediate economic relief or stimulus, a feature explicitly excluded from the design of non-refundable corporate incentives like the Alaska R&D credit.
Business Impact: Cash Flow and Strategic Tax Planning
The non-refundable status fundamentally shapes a business’s approach to the R&D incentive. Because the credit’s immediate cash benefit is strictly limited to the reduction of the current year’s tax payment, companies must look beyond the present filing period to fully monetize their qualified research expenditures (QREs).6 For a growing technology firm or a capital-intensive research entity that is currently in a pre-profitability phase or generating minimal taxable income, the generated credit holds no immediate monetary value. It cannot be converted into working capital or invested back into operations instantly.
This delay in realization reduces the Net Present Value (NPV) of the incentive. When a company with low or zero current taxable income must wait potentially many years for future profitability to absorb the accumulated credit, the economic value derived from that credit diminishes over time compared to a fully refundable incentive. This dynamic mandates that corporate finance and tax departments view the unused credit as a deferred tax asset, requiring detailed multi-year projections and sophisticated capital budgeting to accurately gauge the long-term return on R&D investment. Tax strategies must emphasize optimizing credit utilization across the full legal carryforward window, rather than focusing on rapid cash recovery.6
A summary comparison of the distinct features of these credit types illustrates this fundamental strategic difference:
Table 1: Comparison of Tax Credit Types
| Feature | Non-Refundable Tax Credit | Refundable Tax Credit |
| Reduces Liability Below Zero? | No (Maximum reduction to $0 liability) 1 | Yes (Generates a cash refund) 7 |
| Treatment of Excess Credit | Carried over (forward or back) or forfeited 4 | Paid out to the taxpayer as a refund |
| Strategic Planning Requirement | High (Requires long-term liability projection) | Moderate (Focus on immediate eligibility) |
III. Statutory Framework and Calculation of the Alaska R&D Credit (AS 43.20.021)
The implementation of the Alaska R&D Tax Credit is governed by Title 43, Revenue and Taxation, specifically AS 43.20.021(d), which establishes the eligibility, calculation formula, and major limitations of the incentive.
Eligibility Requirements: Entities and Qualifying Research Expenditures (QREs)
The credit is accessible to various business structures, including C-corporations, S-corporations, Limited Liability Companies (LLCs), and Partnerships.3 A notable exclusion from eligibility is the sole proprietorship business structure.3
The foundation of the Alaska credit is its dependence on the federal definition of Qualified Research Expenditures. To be eligible for the Alaska incentive, a business must first establish eligibility for the federal R&D credit (under IRC § 41), which is determined by satisfying the rigorous four-part test.3 The state’s eligibility criteria confirm that a business conducting operations within Alaska that satisfies the federal definition of qualified research is eligible to claim the corresponding state credit.3
The Calculation Nexus: 18% of the Federal Credit (AS 43.20.021(d))
The calculation of the Alaska R&D credit is straightforward, yet it includes a critical apportionment requirement for multi-state businesses. Alaska law stipulates that the credit is limited to 18 percent of the total credit amount determined for federal income tax purposes.5
For taxpayers operating solely within Alaska, the calculation is a direct application of the 18% rate to the computed federal credit. However, for companies conducting business both inside and outside of Alaska, the statutory language requires that the 18% limit applies only to the credit amount “which is attributable to Alaska”.5 This necessitates a complex initial step where the federal credits generated must be accurately apportioned to Alaska using the state’s established allocation formulas before the 18% rate is applied.9
The effective benefit realized by a multi-state taxpayer is, therefore, tied directly to the precision of the apportionment calculation. If a substantial portion of the company’s business activity base or underlying QREs occurs outside Alaska, the state-attributable segment of the federal credit will be smaller, resulting in a proportionately lower state R&D credit. This interdependence requires specialized State and Local Tax (SALT) analysis to ensure compliance with AS 43.20.021(d) and to maximize the credit generated from the Alaska slice of the business operation.9
Statutory Prohibitions and Exclusions
Alaska’s tax statutes include clear prohibitions designed to prevent the misuse or excessive accumulation of the R&D credit, reinforcing its specific role as an offset against corporate income tax.
- No Double Dipping: A taxpayer is explicitly barred from claiming a deduction when calculating Alaska corporate net income tax for any expenditure that is simultaneously used as the basis for claiming the R&D credit.10 This mandate forces the taxpayer to elect the most beneficial tax treatment for their QREs: either the immediate, full deduction (reducing taxable income) or the credit (a dollar-for-dollar reduction of the final tax bill). The choice often hinges on whether the immediate credit benefit, subject to the non-refundable limitation, outweighs the benefit of reducing the overall corporate taxable base.
- Credit Siloing: The expenditure claimed for the R&D credit (AS 43.20.049) may not be used to claim a credit against any other type of tax levied by the state.10 This maintains the integrity of the incentive, ensuring it is focused solely on reducing corporate income tax liability.
- Distinct Incentives: The 18% limitation specified in AS 43.20.021(d) is distinct from other state incentives and specifically does not apply to credits such as the special industrial incentive tax credit under AS 43.20.042.5 This legislative distinction confirms the siloed nature of Alaska’s tax incentive programs.
IV. Local State Revenue Office Guidance and Compliance (Alaska DOR)
Compliance with the Alaska R&D credit relies on specific administrative guidance and filing procedures established by the Alaska Department of Revenue (DOR). Taxpayers must follow these protocols carefully, particularly concerning required forms and the application of the non-refundable rule.
Claiming the Credit: Alaska Form 6390 – Alaska Federal-based Credits
To claim the R&D credit, which is calculated based on the federal credit, corporations must submit Alaska Form 6390, titled “Alaska Federal-based Credits,” alongside their primary corporate income tax return (such as Form 6000, 6100, or 6150).9 Form 6390 serves as the administrative mechanism for the DOR to order and strictly limit the application of federal-based credits, verifying adherence to the 18% state cap and ensuring that any required apportionment has been executed correctly.11
The documentation required to substantiate the claim for the state credit is directly tied to the materials used for the federal claim.3 Businesses must retain and potentially present detailed evidence demonstrating the qualified nature of the expenditures, including general ledger details, relevant payroll records, project notes, and lab results, all of which confirm that the expenditures meet the stringent federal four-part test for R&D.3
Limitations on Application: The Non-Refundable Constraint in Practice
DOR guidance reinforces the statutory limits of the R&D credit, particularly in the context of alternative taxation methods. A crucial restriction is that the R&D credits attributable to Alaska cannot be applied against the Alaska Alternative Minimum Tax (AMT) or other state taxes.9 The mandatory Form 6390 reflects this restriction by requiring separate calculations for the regular tax offset (Line 9) and the AMT offset (Line 10), underscoring that the R&D credit is permitted only to offset the regular corporate income tax.11
This exclusion from the AMT offset is a significant element of the state’s tax policy. If a corporation is operating under the AMT regime, it generally indicates that its regular tax liability is low due to various tax preferences or adjustments. By prohibiting the R&D credit from reducing the AMT, the DOR prevents the credit from offsetting the minimum required payment. This structural choice prioritizes the immediate utility of the R&D credit for companies with high, stable regular tax liabilities. For emerging companies or those with fluctuating income profiles, the inability to apply the credit against the AMT further limits current-year utilization, thereby reinforcing the central importance of the 20-year carryforward period for eventual credit realization.
Table 2 provides a concise summary of the primary compliance points for the R&D credit.
Table 2: Alaska R&D Credit Compliance and Filing Requirements
| Requirement Category | Statutory/DOR Guidance | Filing Instrument |
| Legal Basis | AS 43.20.021(d) (18% of federal credit) 5 | Alaska Corporate Income Tax Return (Form 6000, 6100, or 6150) 11 |
| Credit Calculation | 18% of the apportioned federal credit 4 | Form 6390 (Alaska Federal-based Credits) 11 |
| Allowable Offsets | Regular Alaska Corporate Income Tax Only 9 | Form 6390 (Line 9) |
| Ineligible Offsets | Alaska Alternative Minimum Tax (AMT) or other taxes 9 | N/A (Explicitly prohibited) |
| Eligible Entities | C-Corps, S-Corps, LLCs, Partnerships 3 | N/A |
V. Maximizing Credit Utilization: Carryback and Carryforward Strategy
The core strategic challenge posed by any non-refundable credit is how to maximize its value when current tax liability is insufficient to absorb the full amount generated. For the Alaska R&D credit, the solution is provided through generous carryover provisions.
The Importance of the Carryover Provision for Non-Refundable Credits
The ability to carry unused credit amounts forward or back is the essential feature that mitigates the non-refundable limitation.6 Without this provision, qualified R&D expenditures made during years of low or zero profitability would be wasted, significantly diminishing the incentive’s effectiveness. Instead, the carryover mechanism converts the unused credit into a predictable, long-term tax attribute, ensuring that the state’s commitment to incentivizing R&D investment remains viable regardless of a company’s immediate financial performance.6
Detailed Rules: The 1-Year Carryback and 20-Year Carryforward Lifespan
Alaska law permits unused R&D tax credits to be carried back one year and carried forward for a maximum period of 20 years.3
This extended 20-year carryforward period is particularly robust and aligns with general federal standards for qualified business credits.4 The longevity provided by this term offers significant certainty to corporations engaged in long-cycle R&D projects, allowing them to confidently accrue tax assets during early development stages, knowing those assets will likely be available when the ventures achieve eventual profitability and generate a substantial tax liability.
Strategy for Startups and Fluctuating Revenue Streams
For companies with uneven or initially non-existent income streams, the management of R&D credits must be rigorous. Tax departments should implement careful tracking protocols, treating the banked credit as a distinct capital asset with a 20-year expiration clock.6
The limited 1-year carryback feature provides a valuable, albeit narrow, avenue for rapid monetization. This is most beneficial for profitable companies that experience a sudden, large increase in R&D spending, which reduces their current taxable income and results in a large unused credit. The carryback allows them to promptly retrieve taxes paid in the previous year.4
Moreover, the extended carryforward period significantly impacts corporate valuation, particularly during mergers and acquisitions (M&A) or other corporate exits. The availability of a large volume of unutilized R&D tax credits enhances the financial viability of an R&D-intensive target company, even if it is currently unprofitable. An acquiring, profitable entity can often utilize the target company’s accumulated tax attributes. Thus, the 20-year carryforward acts as an implicit long-term financial stimulus for the entire R&D sector by boosting the M&A attractiveness of businesses that have invested heavily in innovation within Alaska.6
VI. Case Study: Application of the Non-Refundable Alaska R&D Credit
This detailed case study illustrates the functional constraints of the non-refundable rule, demonstrating how a calculated R&D credit is applied against the Alaska corporate income tax and how any unused portion is managed through the required carryforward process.
Scenario Definition: A Mid-Sized Alaskan Technology Company (C-Corp)
TechAlaska Corp. is a C-Corporation operating entirely within Alaska, meaning no multi-state apportionment is required. The company’s financial data for Year X is as follows:
- Alaska Taxable Income (ATI): $150,000
- Calculated Federal R&D Credit (Attributable to Alaska): $55,556
Step 1: Determining Pre-Credit Alaska Tax Liability
Alaska utilizes a graduated corporate income tax rate structure.13 The pre-credit tax liability is calculated by applying these rates to the company’s ATI of $150,000.
Table 3: Alaska Corporate Income Tax Rate Structure (AS 43.20.021)
| Alaska Taxable Income (ATI) | Tax Rate on Bracket | Tax Base | Tax Calculation | Cumulative Tax |
| Less than $25,000 | 0% | $25,000 | $0 | $0 |
| $25,000 to $49,000 | 2% | $24,000 | $480 | $480 |
| $49,000 to $74,000 | 3% | $25,000 | $750 | $1,230 |
| $74,000 to $99,000 | 4% | $25,000 | $1,000 | $2,230 |
| $99,000 to $124,000 | 5% | $25,000 | $1,250 | $3,480 |
| $124,000 to $148,000 | 6% | $24,000 | $1,440 | $4,920 |
| $148,000 to $150,000 (Excess) | 7% | $2,000 | $140 | $5,060 |
| Total Pre-Credit Alaska Tax Liability | N/A | $150,000 | N/A | $5,060 |
Based on the graduated rate structure 14, the total tax liability for TechAlaska Corp. prior to the application of any credits is $5,060.
Step 2: Calculating the Allowable Alaska R&D Credit
The Alaska R&D Credit is calculated as 18% of the federal R&D credit attributable to the state.4
$$\text{Calculated Alaska Credit} = \$55,556 \times 0.18 = \$10,000$$
The total calculated Alaska R&D credit for Year X is $10,000.
Step 3: Application and Non-Refundable Limitation
The calculated credit ($10,000) is now applied against the Pre-Credit Tax Liability ($5,060).
Since the credit is non-refundable, it can only reduce the liability down to zero and cannot exceed the total tax owed.1
- Current Year Credit Utilized: $5,060
- Remaining Tax Liability: $0
- Unused Credit: $\text{\$10,000} – \text{\$5,060} = \mathbf{\$4,940}$
Managing the Unused Credit
The $4,940 unused credit is considered a tax attribute of TechAlaska Corp. Because it is non-refundable, this amount is not returned to the company in the current year. Instead, the company has the option to carry this unused credit back one year or, more commonly, carry it forward for a maximum of 20 subsequent years to offset future Alaska corporate tax liabilities.3
Table 4: R&D Credit Utilization: Current Year Application and Carryforward
| Metric | Value | Source/Calculation |
| 1. Alaska Taxable Income (ATI) | $150,000 | Scenario Input |
| 2. Pre-Credit Alaska Tax Liability | $5,060 | Calculated using graduated rates 14 |
| 3. Calculated Alaska R&D Credit | $10,000 | 18% of Federal Credit 5 |
| 4. Current Year Credit Utilized | $5,060 | Limited by Pre-Credit Liability (Non-Refundable Rule) 1 |
| 5. Remaining Tax Liability | $0 | (2) – (4) |
| 6. Unused Credit (Carryforward) | $4,940 | (3) – (4) (Carried back 1 year/forward 20 years) 4 |
This example highlights that the non-refundable structure has a disproportionate impact on smaller firms or those with lower taxable income, such as TechAlaska Corp. Due to the graduated rate structure, smaller entities face lower effective tax rates compared to large multinational corporations, meaning their current tax liability is often insufficient to fully utilize a large R&D credit. Consequently, the 20-year carryforward is not just a secondary benefit for these emerging businesses; it is the essential feature that allows them to eventually monetize the R&D incentive and realize the financial reward for their innovative expenditures.13
VII. Conclusion and Strategic Recommendations
The Alaska R&D Tax Credit is a vital component of the state’s economic development policy, offering a substantial incentive calculated at 18% of the federal qualified research credit. However, its designation as a non-refundable tax credit imposes specific constraints that require meticulous financial management and long-term tax projection. The state’s careful design—enforced through Department of Revenue guidance and the mandatory use of Form 6390—maintains fiscal integrity by preventing dual benefits (no concurrent deduction) and strictly limiting the offset only to the regular corporate income tax.9
The analysis confirms that the non-refundable nature of the credit shifts the focus from immediate cash recovery to the strategic management of a long-term tax asset. For companies, particularly those in the R&D phase with low or fluctuating current profitability, the 20-year carryforward provision is the defining factor that ensures the economic viability of the incentive.
Strategic Recommendations for Utilization
To maximize the benefits of the Alaska R&D Tax Credit while managing the non-refundable limitation, corporations should adopt the following strategic imperatives:
- Maximize Federal Eligibility: Since the Alaska credit is entirely dependent upon the federal IRC § 41 claim, businesses must first prioritize maximizing and rigorously documenting their federal Qualified Research Expenditures (QREs). A robust federal claim is the prerequisite for generating the largest possible 18% state credit base.3
- Rigorous Tracking of the Tax Attribute: Tax systems must be implemented to accurately track and manage the accumulated unused credit throughout the full 20-year carryforward period. This tracking should include annual recalculation of the credit’s Net Present Value (NPV) to inform corporate financial forecasting and long-term budgeting.4
- Plan for Accelerated Monetization: For companies currently generating significant unused credit, the non-refundable nature provides a powerful financial incentive to strategically accelerate the achievement of taxable income. Projections must estimate the specific future tax year in which the accumulated credit balance will be fully utilized, thereby quantifying the expected return on the R&D investment.
Scrutinize Apportionment Calculations: For multi-state entities, the apportionment process that determines the credit amount “attributable to Alaska” is highly sensitive and directly affects the eligible 18% base. Expert SALT review is required to ensure that the apportionment calculation is accurate and maximizes the justifiable portion of the federal credit allocated to the state.5

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.
