Colorado Considers Legislation to Tax Phantom Income

The contentious House Bill 26-1221, currently under consideration in the Colorado legislature, proposes significant alterations to the state’s tax code that have ignited a fierce debate among policymakers, business leaders, and tax experts. At its core, the legislation aims to generate additional state revenue by modifying the existing alternative minimum tax (AMT) provisions and imposing new limitations on net operating loss (NOL) deductions. Critics argue that these changes would effectively tax income that does not genuinely exist in an economic sense, leading to double taxation, distorting taxpayer behavior, and potentially undermining Colorado’s competitive economic environment. The bill represents a departure from the state’s historically streamlined tax system, which has largely mirrored federal policy, raising concerns about its long-term implications for businesses and individuals across the state.

Understanding the Legislative Context: HB 26-1221

House Bill 26-1221 emerges amidst ongoing discussions about state fiscal health and the allocation of resources in Colorado. While the specific impetus for the bill is not explicitly detailed in the original legislative text, it can be inferred that the proposed changes are part of a broader effort to bolster state revenues, potentially to fund public services, address budgetary gaps, or support new initiatives. Legislators supporting the bill may argue that these adjustments are necessary to ensure that all entities contribute equitably to the state’s financial well-being and to close perceived "loopholes" that allow some businesses and high-income earners to reduce their tax liabilities. However, the methods proposed—specifically targeting the AMT credit and NOL utilization—have drawn sharp criticism for their potential to create unintended economic consequences rather than simply leveling the playing field.

Colorado has long maintained a reputation for a relatively simple and broad-based tax system, characterized by lower rates and a high degree of conformity with the federal tax code. This approach has historically contributed to a predictable and stable environment for businesses. HB 26-1221’s provisions, particularly those related to "phantom income," are seen by many as a significant deviation from these established principles, potentially positioning Colorado as an outlier among states in its approach to corporate and individual taxation.

Double Taxation Under the Alternative Minimum Tax: A Closer Look

One of the most significant provisions within HB 26-1221 involves the state’s alternative minimum tax (AMT). Colorado is notable for being one of the few states that still maintains an AMT, a parallel tax system designed to ensure that taxpayers benefiting from numerous deductions and credits pay at least a minimum amount of tax. The AMT operates by disallowing many standard deductions and credits, calculating tax liability under a separate set of rules, and then requiring taxpayers to pay the higher of their regular tax or their AMT liability.

The Historical Context of AMT
The concept of the AMT originated at the federal level in 1969, primarily to prevent a small number of very wealthy individuals from using various tax shelters and deductions to pay little to no federal income tax. Over the decades, its scope expanded significantly, ensnaring millions of middle-income taxpayers due to its failure to be indexed for inflation. The complexity and compliance burden associated with the federal AMT became a perennial point of contention. Recognizing these issues, the Tax Cuts and Jobs Act (TCJA) of 2017 dramatically curtailed the federal AMT, raising exemption amounts and phase-out thresholds, effectively reducing the number of filers subject to it to a small fraction of what it once was.

In response to the federal changes and the inherent complexity of the AMT, most states that once had a parallel state AMT system have since repealed theirs. The argument for repeal was multifold: state income tax codes generally feature far fewer deductions and credits than the federal system, meaning the original rationale for a state AMT—mirroring a federal "problem"—often did not apply neatly. Furthermore, the administrative burden and compliance costs associated with maintaining a separate, complex tax calculation became increasingly difficult to justify for state revenue departments and taxpayers alike. Colorado, with its unusually tight conformity to federal tax law, has remained an exception, maintaining an alternative tax regime that the majority of states have abandoned.

HB 26-1221’s Proposed Change: Repealing the AMT Credit
The critical aspect of HB 26-1221 concerning the AMT is the proposed repeal of the AMT credit. This credit, an integral component of both federal and state AMT systems, is specifically designed to prevent double taxation on what are often considered "timing differences" rather than permanent exclusions of income. Without this credit, the AMT would not merely strip away the immediate benefit of certain provisions; it would permanently tax income that is not true economic income, effectively imposing a surtax on capital investments and certain types of compensation.

Consider two illustrative examples where the AMT credit plays a crucial role:

1. Accelerated Depreciation: The ordinary tax code allows businesses to accelerate the depreciation of certain capital investments, deducting a larger portion of the asset’s cost in its early years. This policy is generally intended to encourage business investment and stimulate economic activity. The AMT system, however, often adds back some of this accelerated depreciation, treating it as if it were regular income. The existing AMT credit ensures that while the immediate tax benefit of accelerated depreciation might be delayed, the business owner still gets those deductions eventually, preventing them from paying income tax on what is essentially a capital investment. Repealing this credit would mean that the "phantom income" generated by the difference between regular and AMT depreciation schedules would be permanently taxed, increasing the effective cost of capital for businesses and discouraging future investments in productive assets.

2. Incentive Stock Options (ISOs): Many employees, particularly in the tech and startup sectors, receive Incentive Stock Options (ISOs) as part of their compensation. When an employee exercises an ISO, the AMT may tax them on the difference between the strike price (the price at which they can buy the stock) and the market value of the stock at the time of exercise, even if they have not yet sold the shares. This gain is "phantom" because it has not been realized; the employee has merely acquired the stock. The existing AMT credit is crucial here: it ensures that employees are not taxed on these paper gains if the stock price subsequently drops before they sell the shares. Without the credit, an employee could be taxed on a significant "gain" that never materializes into actual cash income, creating a substantial financial burden and distorting decisions about when to exercise or sell options. It could force employees to sell shares prematurely to cover a tax liability on income they may never fully realize.

In essence, repealing the AMT credit transforms the AMT from a mechanism to limit the timing of certain tax benefits into a permanent surtax on specific economic activities. This move is not merely a technical adjustment; it represents a fundamental shift in how Colorado would define and tax income, moving towards a system that captures non-existent gains and penalizes productive investment. Business advocacy groups in Colorado have vocally expressed concerns that such a policy would deter new business formation and expansion, particularly in high-growth sectors reliant on stock options and significant capital expenditures.

Limiting Net Operating Loss Deductions: Another Form of Phantom Income Taxation

The second major component of HB 26-1221 that critics argue targets "phantom income" involves new restrictions on net operating loss (NOL) deductions. The ability for businesses to carry forward net operating losses is a cornerstone of sound corporate income tax policy, recognized globally across developed economies. Corporate income taxes are typically levied on annual profits, but the economic reality for most businesses involves cycles of losses and profits over a longer time horizon. Startups, for instance, often incur substantial losses during their initial years as they invest heavily in research and development, product development, and market penetration before achieving profitability. Similarly, businesses in cyclical industries may experience significant losses during economic downturns, followed by periods of profit during recovery.

The Economic Rationale for NOLs
If a corporate income tax were applied solely to profitable years without any mechanism to offset past losses, it would dramatically overtax overall profitability and disproportionately penalize businesses with irregular income streams or those requiring significant upfront investment. NOL carryforwards address this problem by allowing businesses to deduct past losses against future taxable income. This mechanism enables businesses to smooth their taxable income over time, making the tax code more neutral and ensuring that the tax burden aligns more closely with a company’s true long-term economic profitability. Without NOLs, the tax code would effectively discourage risk-taking, innovation, and long-term capital investment.

Federal NOL Policy Evolution
Historically, the federal government allowed net operating losses to be carried forward for 20 years, with no limit on the percentage of taxable income that could be offset in a given year. The TCJA of 2017 brought significant changes to federal NOL policy. While it eliminated the 20-year time limit, allowing losses to be carried forward indefinitely, it simultaneously introduced a new restriction: NOL deductions could only reduce taxable income by up to 80 percent in any given year. This change aimed to provide more flexibility for businesses with very long runways to profitability while ensuring a minimum tax payment even in years with substantial prior losses. Many states subsequently conformed to these federal changes, aligning their state tax codes with the new federal framework. However, some states, including Colorado, maintained their prior approach of a 20-year carryforward period with uncapped utilization.

HB 26-1221’s Proposed Restrictions
Under HB 26-1221, Colorado proposes to drastically limit NOL carryforwards to just 10 years, a reduction from the current 20-year period. Furthermore, the bill would cap the deduction at 70 percent of taxable income in any given year, even more restrictive than the federal 80 percent limit. These proposed changes are explicitly designed to prevent businesses from fully offsetting their losses, thereby forcing them to pay tax on an inflated measure of net income—another instance of taxing "phantom income."

The implications of these restrictions are particularly punitive for several segments of the business community:

• Startups and Emerging Businesses: Many startups operate at a loss for their first 5-10 years, investing heavily in R&D, infrastructure, and market development. A 10-year limit on NOL carryforwards means that a significant portion of their early losses could expire before the company ever achieves sustained profitability, making it impossible to fully recover those losses through future deductions. This effectively increases the tax burden on nascent companies, potentially stifling innovation and growth in critical sectors.
• Highly Cyclical Businesses: Industries that experience significant fluctuations in demand or commodity prices (e.g., energy, manufacturing, agriculture) are particularly vulnerable. During downturns, these businesses may accumulate substantial losses. A 70 percent cap on NOL utilization, combined with a shorter carryforward period, would severely restrict their ability to use these losses during periods of recovery, increasing their cost of capital and making them less resilient to economic shocks. It could also discourage investment during boom times if businesses know their downside protection (via NOLs) is limited.
• Capital-Intensive Industries: Businesses that require substantial capital investment often incur significant upfront costs and losses before generating sustained revenue. The proposed NOL limits would make such investments less attractive by increasing the effective tax rate on their long-term profits.

Business organizations, such as the Colorado Chamber of Commerce and various industry associations, have expressed grave concerns that these NOL limitations would undermine the state’s attractiveness for new businesses and expansions, potentially leading to job losses and reduced economic dynamism. They argue that taxing businesses on an inflated income measure not only distorts economic decision-making but also creates an unfair and unsustainable tax burden that could drive investment to other states with more favorable tax policies.

Broader Economic Implications and Departures from Sound Tax Policy

Both the AMT credit repeal and the NOL deduction limitations embedded in HB 26-1221 represent a significant departure from fundamental principles of sound tax policy, including neutrality, equity, and simplicity. By taxing "phantom income"—income that does not reflect true economic gains or accurately measure long-term profitability—Colorado risks creating a tax environment that is highly distortionary.

Impact on Investment and Competitiveness
The proposed changes could have a chilling effect on capital investment within Colorado. When businesses face the prospect of paying taxes on accelerated depreciation that is never fully offset or on losses that cannot be fully recovered, the incentive to invest in new equipment, facilities, or research and development diminishes. This could slow economic growth, reduce job creation, and make Colorado less competitive compared to states with more neutral tax systems. For individuals, the changes to ISO taxation could discourage entrepreneurship and make it harder for Colorado companies to attract top talent, particularly in sectors where stock options are a common form of compensation.

Colorado as an Outlier
The analysis suggests that these policies would position Colorado as an "extreme outlier" in the national tax landscape. While many states grapple with the need to raise revenue, few are pursuing measures so expressly targeted at taxing income that is not truly economic. The majority of states have either repealed their AMTs or maintained federal conformity, and most have less restrictive NOL policies. This outlier status could send a negative signal to businesses and investors, suggesting an unpredictable and potentially punitive tax environment. In an increasingly mobile economy, states compete fiercely for business investment and talent, and policies that diverge significantly from national norms can have tangible consequences for economic development.

The Debate Over Fairness and Revenue
Proponents of HB 26-1221 would likely frame these measures as essential for fiscal responsibility and fairness, arguing that they ensure wealthy individuals and profitable corporations contribute their share to public services. They might point to the potential revenue generation as a crucial factor in funding schools, roads, and other state priorities. However, critics counter that the long-term economic costs—in terms of stifled innovation, reduced investment, and slower job growth—will ultimately outweigh any short-term revenue gains. They argue that genuine tax reform should focus on broad-based, low-rate systems that minimize economic distortions, rather than on complex, targeted measures that tax non-economic income.

Legislative Outlook and Stakeholder Reactions

As of its introduction, HB 26-1221 faces a rigorous legislative process, including committee hearings and floor votes, where these concerns will undoubtedly be debated. Business groups, led by organizations like the Colorado Business Roundtable and various industry-specific associations, are actively lobbying against the bill, providing detailed analyses of its potential negative impacts on specific sectors and the broader economy. They are likely to emphasize the importance of maintaining a predictable and competitive tax code to foster a robust economic climate. Tax policy experts, including those from non-partisan research institutions like the Tax Foundation, have provided objective analysis, highlighting the economic pitfalls of taxing phantom income and advocating for tax policies that promote long-term economic growth.

The outcome of HB 26-1221 will be a critical indicator of Colorado’s future tax policy direction. It will determine whether the state maintains its historical commitment to a simple, federal-conforming tax code or embarks on a path that could lead to increased complexity, economic distortions, and a less competitive business environment. The debate over phantom income taxation underscores the delicate balance legislators must strike between revenue generation and the foundational principles of sound economic policy.
