Alaska — Corporate Income / Franchise Tax

Alaska imposes a corporate income tax on the taxable income of every corporation derived from sources within the state under AS 43.20.011(e). The tax applies to C corporations only; pass-through entities (S corporations, partnerships, LLCs taxed as partnerships) are not subject to Alaska corporate income tax because their income and losses flow through to individual owners' tax returns, and Alaska repealed its individual income tax in 1980. The tax is computed on a graduated rate structure ranging from 0% on the first $25,000 of taxable income to a top marginal rate of 9.4% on income over $222,000.

Certain small corporations meeting specific qualification requirements under AS 43.20.012 may be exempt from the tax. Alaska does not impose a separate corporate franchise tax.

Alaska corporate income tax returns are due within 30 days after the federal corporate return is required to be filed under AS 43.20.030(a). For most calendar-year C corporations, this means the Alaska return is due May 15 (30 days after the April 15 federal due date). Corporations filing on a fiscal-year basis must file their Alaska return 30 days after their federal due date.

Federal extensions automatically extend the Alaska filing deadline to 30 days after the extended federal due date. When a corporation obtains an extension for its federal return, Alaska allows the same extension period plus the additional 30 days, so no separate Alaska extension application is required.

The statute applies to corporations and to partnerships that have a corporation as a partner. The 30-day deadline is measured from the date the federal return is "required to be filed," meaning the original federal due date (or extended due date if an extension was granted), not the date the taxpayer actually files the federal return.

Alaska's corporate income tax uses ten graduated brackets ranging from 0% to 9.4%, in effect since 1981. The first $25,000 of taxable income is taxed at 0%. Rates then increase in increments: 2% on income between $25,000 and $49,000; 3% on income between $49,000 and $74,000; 4% on income between $74,000 and $99,000; 5% on income between $99,000 and $124,000; 6% on income between $124,000 and $149,000; 7% on income between $149,000 and $174,000; 8% on income between $174,000 and $199,000; 9% on income between $199,000 and $222,000; and 9.4% on income over $222,000.

Multistate corporations doing business both inside and outside Alaska apportion their total income to the state using an equally weighted three-factor formula based on the Multistate Tax Compact, codified at AS 43.19.010. The apportionment percentage is the average of three ratios: (1) Alaska property to total property, (2) Alaska payroll to total payroll, and (3) Alaska sales to total sales. Each factor receives equal one-third weighting. Oil and gas producers and pipeline transporters use modified apportionment formulas under separate statutory provisions.

Alaska imposes corporate income tax on C corporations doing business in the state, but Alaska statutes do not codify bright-line nexus standards comparable to the economic nexus thresholds many states adopted after South Dakota v. Wayfair (2018). Practitioners must instead rely on the statutory language taxing income "derived from sources within the state," constitutional nexus principles, and the absence of Alaska administrative guidance defining what constitutes sufficient connection to trigger filing obligations.

## Statutory foundation: income derived from sources within the state

AS 43.20.011(e) imposes Alaska corporate income tax "upon the entire taxable income of every corporation derived from sources within the state." The statute does not define what connection or presence is required for a corporation to be considered subject to the tax. The imposition language presupposes that nexus exists but does not specify the activities or thresholds that create it.

Alaska Statutes Title 43, Chapter 19 (allocation and apportionment) and Chapter 20 (the Alaska Net Income Tax Act) contain no section titled "nexus" and no enumeration of nexus-creating activities or safe harbors. Legislative fiscal analyses describe the tax as applying to "C-Corporations doing business in the state of Alaska" without further statutory definition of that phrase.

This statutory silence leaves Alaska corporate income tax nexus determinations governed by general constitutional nexus principles—substantial connection to the state sufficient to satisfy due process and Commerce Clause requirements—without state-specific administrative elaboration.

## Physical presence and apportionment factors

Because Alaska uses a three-factor apportionment formula under AS 43.19.010 (property, payroll, and sales), corporations subject to Alaska corporate income tax typically have property or payroll presence in the state. However, the apportionment statute does not itself create or define nexus; it describes how income is apportioned for corporations already determined to be subject to Alaska tax.

In practice, corporations with employees, offices, facilities, inventory, or other physical presence in Alaska are treated as having nexus. Alaska has not enacted legislation establishing economic nexus for corporate income tax based solely on sales volume or transaction count, distinguishing its approach from the remote-seller frameworks many states adopted for sales tax and corporate income tax post-Wayfair.

The scope of activities that create nexus for a corporation with no employees or tangible property in Alaska—such as remote sales facilitated through digital advertising or cloud infrastructure hosted in Alaska—is not addressed by published Alaska Department of Revenue guidance.

## Public Law 86-272 federal protections

Public Law 86-272 (15 U.S.C. §§ 381–384) prohibits a state from imposing a net income tax on an out-of-state corporation whose only in-state activity is the solicitation of orders for sales of tangible personal property, where orders are approved and filled from outside the state. Alaska, like all states, is bound by this federal limitation.

Corporations whose Alaska activities exceed mere solicitation—by installing products, maintaining inventory, providing post-sale services, or performing other in-state functions—may lose P.L. 86-272 protection and thereby create nexus. The Multistate Tax Commission issued revised guidance on P.L. 86-272 in October 2021 detailing protected and unprotected activities, but Alaska has not formally adopted or rejected that guidance, and there is no Alaska administrative position interpreting P.L. 86-272 for Alaska corporate income tax purposes.

## No economic nexus threshold

As of 2026, Alaska has not enacted a corporate income tax economic nexus threshold (such as $100,000 in Alaska sales or 200 transactions). Legislative proposals such as SB 122 in the 33rd Legislature (2023–2024) focused on changing Alaska's apportionment methodology—adopting market-based sourcing and moving certain industries to single-sales-factor apportionment—but did not establish economic nexus standards for remote sellers.

Alaska does not impose a statewide sales tax, so there is no state-level remote-seller sales tax nexus issue. Local jurisdictions that levy sales taxes set their own nexus and collection standards.

## Qualified gas project exception

AS 43.20.145(g) provides a narrow statutory exception to the filing requirement for certain corporations with nexus. A corporation that has signed a legislatively approved contract under AS 43.82 (the Alaska Stranded Gas Development Act) providing for payments in lieu of corporate income tax, and that has nexus with Alaska solely because of its participation in the approved qualified project, is not required to file a corporate income tax return unless the contract requires it. This provision confirms that Alaska law contemplates nexus as a prerequisite to taxation but grants relief for strategically designated projects.

## Practical effect: limited published guidance

Alaska Department of Revenue has not published detailed bulletins, advisories, taxability matrices, or letter rulings clarifying corporate income tax nexus standards. Practitioners face open questions about what level of activity creates nexus for corporations with no employees or tangible property in Alaska—questions common in the digital economy involving telecommuting employees, independent contractors, digital advertising targeted to Alaska residents, or internet sales with no Alaska fulfillment infrastructure.

In the absence of codified nexus thresholds or administrative guidance, corporate income tax nexus determinations in Alaska rest on constitutional principles and the general "doing business" concept. Corporations with physical presence in Alaska—employees, offices, inventory, equipment—are treated as having nexus. The treatment of remote corporations with only sales into Alaska is not addressed by Alaska statute or published administrative authority.

Alaska corporate income tax is calculated on a corporation's taxable income, which begins with federal taxable income and is then subject to Alaska-specific modifications. This starting-point rule is foundational to computing Alaska corporate tax liability.

## Adoption of the Internal Revenue Code

Alaska adopts substantial portions of the Internal Revenue Code by reference under AS 43.20.021. Sections 26 U.S.C. 1–1399 and 6001–7872 of the Internal Revenue Code, as amended, have full force and effect under Alaska's corporate income tax unless excepted to or modified by other Alaska statutory provisions. This means that Alaska generally follows federal rules for determining gross income, allowable deductions, accounting methods, taxable years, and most other computational mechanics.

## Federal taxable income as the base

For corporations subject to Alaska corporate income tax, taxable income is the company's federal taxable income—federal gross income minus allowable federal deductions—with certain Alaska-specific modifications. The federal taxable income figure shown on the corporation's Form 1120 (federal corporate income tax return) serves as the baseline for the Alaska computation.

Alaska does not independently define "gross income" or enumerate a separate list of allowable deductions. Instead, the state incorporates the federal definitions and then layers on state-specific adjustments through other provisions in AS 43.20.

## Alaska modifications to federal taxable income

While AS 43.20.021 adopts federal taxable income as the starting point, Alaska statutes and regulations impose modifications. Common categories of modification include:

• State-specific credits and deductions: Alaska allows certain credits (such as the income tax education credit under AS 43.20.014 and special industrial incentive investment tax credits under AS 43.20.042) that do not exist at the federal level or that are computed differently.
• Federal credits limited to 18 percent: Where a federal tax credit is also allowed for Alaska corporate income tax purposes, AS 43.20.021(d) limits the Alaska credit to 18 percent of the federal credit amount attributable to Alaska.
• Alaska-specific rate adjustments: For example, the alternative minimum tax rate for Alaska corporations is 18 percent of the applicable federal alternative minimum tax (AS 43.20.021(f)), and the accumulated earnings tax is calculated at Alaska-specific rates (4.95 percent on the first $100,000 and 6.93 percent on amounts over $100,000 under AS 43.20.021(g)).
• Exclusions and additions: Certain Alaska-specific provisions may require additions to or subtractions from federal taxable income, such as adjustments related to water's-edge combined reporting elections under AS 43.20.145 or deductions of Alaska net operating losses that differ from federal treatment.

Practitioners should carefully review both the federal return and Alaska-specific statutory provisions to identify all applicable modifications. The Alaska Department of Revenue's corporate income tax forms and instructions enumerate the required adjustments in the order they must be applied.

## Interaction with apportionment

For multistate corporations, the taxable income figure (after Alaska modifications) is then apportioned to Alaska using the three-factor formula under AS 43.19.010. The apportioned Alaska income is the amount subject to Alaska's graduated rate structure under AS 43.20.011(e). Only corporations doing business solely within Alaska use their entire taxable income without apportionment.

## Why this matters

Understanding that Alaska starts with federal taxable income and then applies modifications is critical for:

• Return preparation: Practitioners must first complete the federal Form 1120 (or consolidated return) before they can determine Alaska taxable income.
• Audit planning: Adjustments to the federal return (whether by the IRS or by amended filing) generally flow through to Alaska. AS 43.20.030(i) requires taxpayers to file an amended Alaska return within 60 days of any final federal determination that changes federal taxable income.
• State-specific planning: Certain transactions that are neutral or favorable at the federal level may create Alaska-specific additions, and vice versa. Practitioners advising multistate corporations should model the Alaska modifications separately.

The Alaska Legislature has periodically enacted conformity updates or decoupling provisions (for example, the state's treatment of certain federal Tax Cuts and Jobs Act provisions), so practitioners should confirm that Alaska has adopted the version of the Internal Revenue Code in effect for the tax year in question.

Alaska previously provided a temporary corporate income tax exemption for certain qualified small corporations under AS 43.20.012(a)(3). The exemption was enacted by Chapter 55, SLA 2013 (Senate CS for CS for House Bill No. 252) and applied to tax years beginning after December 31, 2012, and before July 1, 2023. It covered Alaska corporations that met the active business requirements of 26 U.S.C. § 1202(e) (as in effect January 1, 2012) and were not engaged in construction, transportation, utility, or fisheries businesses. The exemption expired as scheduled on July 1, 2023, and no corporation may claim the exemption for tax years beginning on or after that date.

However, new legislative activity is underway to revive and make the exemption permanent. House Bill 94, introduced in the 34th Alaska Legislature in February 2025, would re-enact the small business C corporation exemption and make it permanent (removing the sunset). As of June 2026, HB 94 has been introduced but not yet enacted; thus, the exemption remains expired for all open tax years, but this is an area practitioners should monitor for future changes. If enacted, the small corporation exemption under AS 43.20.012 would again become available for qualifying entities.

For historical context: during the period of effectiveness, the exemption relied on federal definitions as of January 1, 2012, and excluded certain industries. Corporate groups were aggregated for exemption tests. Because the law incorporated a sunset and was designed for a limited period, only corporations filing for tax years that began prior to July 1, 2023, may avail themselves of the exemption.

Alaska corporations subject to corporate income tax are required to make estimated tax payments following the same schedule and rules that apply to federal corporate estimated taxes under the Internal Revenue Code. Alaska has no separate state-specific estimated tax payment schedule, safe harbor rules, or penalty calculation—the state adopts the federal framework by reference.

## Payment timing: same as federal

AS 43.20.030(c) provides that "the total amount of tax imposed by this chapter is due and payable to the department at the same time and in the same manner as the tax payable to the United States Internal Revenue Service." This language governs both final tax payments and estimated tax installments.

Because Alaska requires payment "at the same time and in the same manner" as federal payments, corporations must make Alaska estimated tax payments on the same quarterly deadlines as their federal estimated tax payments under IRC § 6655. For calendar-year corporations, the four quarterly estimated tax installment due dates are:

• April 15 (1st quarter)
• June 15 (2nd quarter)
• September 15 (3rd quarter)
• December 15 (4th quarter)

Fiscal-year corporations follow the corresponding dates based on their fiscal year under the federal rules.

## Federal safe harbors apply by reference

Alaska adopts IRC §§ 1–1399 and 6001–7872 by reference under AS 43.20.021. Consequently, the federal safe harbor rules for avoiding estimated tax underpayment penalties in IRC § 6655(d) apply for Alaska purposes as well.

A corporation can avoid Alaska estimated tax penalties if its quarterly payments equal or exceed the lesser of:

1. 100% of the prior year's tax liability (if the corporation filed an Alaska return for the prior year and that year was a full 12 months), or
2. 100% of the current year's tax liability computed on an annualized income basis for the months in the installment period.

Large corporations (those with taxable income of $1 million or more in any of the three preceding years) cannot use the prior-year safe harbor for installments after the first quarter under IRC § 6655(d)(2), as incorporated by Alaska law. Alaska applies this federal limitation in the same manner as the IRS.

## Underpayment penalty calculation

Alaska imposes an underpayment penalty using the same methodology as IRC § 6655. The penalty is calculated as interest on the underpayment for the period between the installment due date and the earlier of the actual payment date or the return due date.

The interest rate for Alaska corporate tax underpayments is set by the Department of Revenue. Alaska does not use the federal underpayment interest rate; the state sets its own rate, but the calculation method—measuring the underpayment amount and the number of days late—follows IRC § 6655.

Corporations that underpay Alaska estimated taxes must complete Alaska Form 0405-708, Underpayment of Estimated Tax by Corporations, and attach it to their Alaska corporate income tax return (Form 0405-611). The form applies the IRC § 6655 framework to compute the penalty amount.

## Practical application

Alaska corporations should:

• Calculate both their federal and Alaska estimated tax liability each quarter.
• Make Alaska estimated payments on the same quarterly schedule as federal payments (April 15, June 15, September 15, and December 15 for calendar-year corporations).
• Apply the federal safe harbor tests under IRC § 6655(d) to determine the minimum required payment for each quarter.
• Use the same annualized income method, if elected for federal purposes, when computing Alaska installments.
• Complete Form 0405-708 if an underpayment occurs and attach it to the annual Alaska return.

Because Alaska corporate tax is imposed on Alaska-apportioned income and computed at Alaska's graduated rate structure (AS 43.20.011(e)), the dollar amount of Alaska estimated tax will differ from the federal amount. However, the timing, safe harbor tests, and penalty calculation method are identical to the federal rules.

Alaska corporate income tax law provides for rolling conformity to the federal Internal Revenue Code (IRC).

Rolling conformity mechanism Under AS 43.20.021(a), Alaska adopts IRC Sections 1–1399 and 6001–7872 “as amended.” This language means that Alaska conforms to the IRC as it exists at any given time, not to a particular version or cutoff year. The law does not require annual legislative updates to adopt federal changes—instead, federal amendments are automatically incorporated for state corporate income tax purposes, unless Alaska specifically amends its statutes to decouple from a new federal provision.

Definition established in statute Alaska statutes further reinforce this with the definition of “Internal Revenue Code” as the federal code “as it exists now or as hereafter amended.”

No decoupling identified since 2023 As of June 16, 2026, there have been no enacted statutory amendments or Alaska Department of Revenue regulations that decouple or materially depart from Alaska’s rolling conformity approach for corporate income tax purposes. The relevant statutory language remains unchanged and no bulletins or administrative guidance indicate Alaska has opted out of any significant federal amendments made since 2023.

Practical effect Alaska-specific computation differences do exist (such as special rules for certain credits and deductions), but these do not affect the rolling conformity to the IRC as the baseline for computing taxable income. Practitioners should monitor for legislative or regulatory changes, but as of the stated date, Alaska continues to match the IRC for corporate income tax, except where Alaska law expressly provides a modification.

Alaska requires corporations engaged in a unitary business group to file on a combined basis for corporate income tax purposes, using either water’s-edge or worldwide reporting depending on the taxpayer’s industry and circumstances.

Combined or consolidated filing Under 15 AAC 20.100(a)–(d), corporations that are part of a unitary business and join in filing a federal consolidated return are required to file a consolidated Alaska return. This requirement applies to any affiliated group engaged in a unitary business (as construed by Alaska law and 15 AAC 20.100(b)), and certain federal exceptions (IRC § 1504(b)) are disregarded (15 AAC 20.100(c)). If eligible, a group not filing federally may still file combined in Alaska (15 AAC 20.100(d)).

Definition of unitary business group A unitary business group, as used in these rules, refers to corporations under common ownership or control (directly or indirectly) and operated as a unitary business (15 AAC 20.100(b), 15 AAC 20.351). Alaska’s regulations incorporate the concept of a flow of value, not merely common ownership.

Water’s-edge combined reporting: general rule Most unitary business groups must use the water’s-edge combined reporting method per 15 AAC 20.330 and AS 43.20.145. Under 15 AAC 20.335(a), the water’s-edge group includes all U.S. corporations in the affiliated group (50% or more voting control), certain foreign corporations treated as domestic under IRC, corporations with Alaska factors exceeding 20% of total, "tax haven" entities, or others with U.S. activity exceeding thresholds. 15 AAC 20.345 details specific inclusion/exclusion rules—such as the inclusion of controlled foreign corporations if more than 20% of their property, payroll, or sales is in the U.S., or if they operate in a listed tax haven.

Worldwide reporting: oil and gas and DOR election Oil and gas producers are required to use worldwide combined reporting with a specialized apportionment formula, as explicitly stated at 15 AAC 20.305(e) and 15 AAC 20.301(d). Additionally, if a taxpayer fails to comply with disclosure or documentation requirements, the Department may mandate worldwide combined reporting for that group (15 AAC 20.330(c)-(d)).

Water’s-edge election and transition There is no separate water’s-edge "election" in Alaska; it is the default for most, except those meeting the worldwide reporting requirements above. The regulations in Article 3 set forth the transition to worldwide reporting if reporting requirements are not met.

Effective authority These rules remain in force as of the current codification of 15 AAC, with 15 AAC 20.100–20.345 current through May 2025 and last confirmed by the 2024 Alaska Department of Revenue Annual Report.

Despite active legislative developments in the 2025–2026 session, no changes to Alaska’s corporate income tax rates, bracket thresholds, or graduated structure have been enacted for tax years beginning after March 2025. The existing rate schedule under AS 43.20.011(e)—with ten brackets topping out at 9.4 percent on income over $222,000—remains in force for the 2026 tax year and beyond.

In contrast, House Bill 280 of the 34th Legislature proposes shifting Alaska’s apportionment methodology from cost-of-performance sourcing to market-based sourcing, aligning the state with a modern sourcing standard used by 36 other states. The bill does not amend tax rates or brackets. As of June 1, 2026, the bill has been passed by both chambers and transmitted to the governor, but has not yet been enacted, and therefore is not effective for any current tax year.

Taxpayers should continue utilizing the existing graduated rate schedule and three-factor apportionment formula under AS 43.20.011 and AS 43.19.010 until such time as HB 280 (or another measure) becomes law and is codified by statute or regulation, at which point this guidance will require updating.

Alaska corporate income tax allows a deduction for net operating losses (NOLs), which are defined and determined through Alaska’s apportionment and allocation rules (15 AAC 20.100). For taxpayers filing on a combined or consolidated basis, NOLs are calculated on a group basis under federal consolidated return principles, then apportioned to Alaska for the loss year.

Alaska’s link to federal NOL treatment: 15 AAC 20.100(h) states that, except where Alaska law or regulation provides otherwise, taxpayers must carry forward or carry back their net operating loss "in accordance with the Internal Revenue Code." This means that Alaska generally follows the federal framework for NOL carryover and carryback, subject to any Alaska-specific limitations. For multistate or multinational filers, the NOL considered for carryover or carryback is only the portion apportioned to Alaska.

Alaska regulations on NOL usage: For oil and gas taxpayers (i.e., those transitioning between AS 43.20 and AS 43.21 corporate tax regimes), Alaska provides specific rules: NOLs incurred under AS 43.20 may be carried forward for up to 15 years and offset Alaska income under AS 43.21 (15 AAC 21.650). Unused portions may be applied against future AS 43.21 income, but only to the extent of the Alaska-apportioned amount. This 15-year carryforward is set out explicitly for oil and gas taxpayers subject to transition between tax regimes.

Absence of explicit period for general corporate filers: For C corporations taxable only under AS 43.20 (not oil and gas), there is no explicit statutory or regulatory provision establishing a standard NOL carryover or carryback period under Alaska law. The regulations direct taxpayers to follow the IRC by default, but neither Alaska statutes (AS 43.20) nor regulations (15 AAC 20.100) specify the maximum period or any differences from federal law for these taxpayers. As of June 2026: Unable to confirm as of 2026-06-22.

## Direct answer Alaska does not allow net operating loss (NOL) carrybacks for C corporations, and permits NOL carryforwards for no more than five years. This materially diverges from the federal Internal Revenue Code (IRC) treatment, which allows indefinite carryforwards for losses arising after 2017 under the Tax Cuts and Jobs Act (TCJA). The five-year limitation and prohibition of carrybacks were established by SB 154, effective for tax years starting January 1, 2024. There is no special exception for oil and gas filers under AS 43.20; statutory reference to federal IRC periods no longer controls for Alaska purposes after this change.

## Why Historically, Alaska adopted rolling conformity to the IRC for NOLs under AS 43.20.021 and 15 AAC 20.100(h), but in 2024 Alaska enacted SB 154, which decoupled the allowable NOL periods from federal law. New statutory language makes clear that, for losses incurred in tax years beginning on or after January 1, 2024, NOL carrybacks are not permitted and NOLs may only be carried forward up to five years following the loss year. Filers must track separate Alaska NOL schedules and may not rely on the federal indefinite carryover or any IRC carryback period for Alaska filings.

## Source support

• SB 154 (2024) amended Alaska's corporate income tax provisions: "A net operating loss may not be carried back to a tax year before the loss year. A net operating loss may be carried forward, but not more than five years after the loss year." (Text of SB 154)
• 15 AAC 20.100(i): prior rule incorporated IRC by reference except as limited by Alaska statute, but now expressly superseded by SB 154 for periods after 2023 (15 AAC 20.100)

## Caution / review status Not yet human confirmed. This update reflects a substantive statutory amendment effective beginning with the 2024 tax year. Filers should carefully track Alaska NOL computation separately from federal, and monitor for future clarifications by regulation or agency guidance. Oil and gas filers should review transition provisions if subject to both AS 43.20 and AS 43.21.

Alaska imposes specialized apportionment formulas for oil and gas producers and pipeline transporters, diverging from the general three-factor formula (property, payroll, sales) used under the Multistate Tax Compact (AS 43.19.010). The rules for these industries are codified at AS 43.20.144 and further clarified by regulation at 15 AAC 20.490.

Summary of statutory formulas:

• If a corporation only transports oil or gas in Alaska during the tax year, its Alaska apportionment factor is the average of the property factor and the sales factor: (Property factor + Sales factor) ÷ 2.
• If it only produces oil or gas in Alaska, the apportionment factor is the average of the property factor and the extraction factor: (Property factor + Extraction factor) ÷ 2.
• If it both produces and transports oil or gas in Alaska (directly or through related corporations), the apportionment factor is the average of all three: (Property factor + Sales factor + Extraction factor) ÷ 3.

Definitions of factors:

• Property factor: Numerator is the average value of real and tangible personal property in Alaska, plus the cumulative intangible drilling and development costs for producing wells in Alaska; denominator is the same property and costs everywhere.
• Sales factor: Numerator includes the total of pipeline tariffs allowed or received for oil/gas transported in Alaska, and proceeds from sales of oil/gas in Alaska, with certain exclusions. Denominator is the same items everywhere.
• Extraction factor: Numerator is the sum of barrels of oil (net of royalty) produced in Alaska and one-sixth of the thousands of cubic feet (Mcf) of gas (net of royalty) produced in Alaska. Denominator is the same computation everywhere.

For taxpayers in affiliated groups, the statute provides rules for combining extraction and transportation activities across entities to prevent manipulation of apportionment factors.

Authority: AS 43.20.144(a)–(f) sets out these formulas, and 15 AAC 20.490 clarifies relevant definitions and computational mechanics. These special formulas override the standard Multistate Tax Compact three-factor apportionment for the specified industries.

Direct answer: An out-of-state corporation will generally have Alaska corporate income tax nexus if it has one or more employees or contractors physically performing work within Alaska—including telecommuting employees—regardless of whether the employer itself has property or business facilities in the state. Alaska statutes and regulations do not set a minimum duration, percentage of time, or other bright-line threshold; any presence of a worker conducting business activity in Alaska ordinarily triggers nexus.

Why: Alaska Statutes AS 43.20.040(b) provide that compensation for services rendered in the state is "income from sources in the state." 15 AAC 20.900(3) defines "does business in the state" broadly, including conducting any business activities or any activity from which income is realized or derived within Alaska. The Department of Revenue’s instructions for Form 6000 (Corporate Net Income Tax Return) confirm that "presence of employees in the state for business purposes" is treated as a nexus-creating activity for the Alaska corporate income tax, with no stated de minimis threshold.

Alaska law does not provide a minimum number of days or quantitative threshold for physical presence by employees or contractors. Unlike some sales tax regimes which define a day-count or dollar standard, Alaska’s corporate income tax nexus arises as soon as an employee or agent is present in-state and carries out any business for the out-of-state employer. The law does not distinguish between traditional office, hybrid, or telecommuting workers for nexus purposes. No administrative bulletins or safe harbor guidance addressing remote or hybrid work were published as of June 2026.

• 2025 Alaska Form 6000 Corporate Net Income Tax Return instructions, p. 4 (DOR: Nexus example includes "presence of employees in the state for business purposes", current as of 2025)

Caution / review status: Not yet human confirmed. No published DOR bulletins, rulings, or FAQs set a day or dollar threshold for remote/hybrid work as of June 2026. Practitioners should monitor for future post-pandemic administrative updates, but the prevailing interpretation is that any in-state employee presence triggers nexus for the employer.

Alaska’s water’s‑edge combined reporting regime for corporate income tax includes corporations defined as “tax haven corporations” under AS 43.20.145(a)(5) (previously AS 43.20.073(a)(5)). A “tax haven corporation” is one that is incorporated in or does business in a jurisdiction that imposes no income tax or imposes an income tax at a rate less than 90 percent of the U.S. rate, derives more than 50 percent of its payments from related parties in the group, and does not conduct significant economic activity in that jurisdiction.

Importantly, Alaska does not maintain or publish a list of countries or jurisdictions specifically designated as “tax havens” for water’s-edge purposes. The statute and regulation (15 AAC 20.345) describe a criteria-based inclusion, not a jurisdictional list. There is no regulatory appendix, administrative bulletin, or annual Alaska DOR publication providing an official or updated list of designated tax haven jurisdictions.

As of June 22, 2026, determining whether a given foreign member must be included as a “tax haven corporation” for Alaska combined reporting is a fact-based analysis using the statutory and regulatory criteria described above. Taxpayers and practitioners must evaluate each potentially includable foreign entity under the statutory test; the Alaska Department of Revenue does not issue or maintain any roster or proactive notices updating a set list of included or excluded jurisdictions.
