Colorado taxpayers will receive reduced TABOR refunds this tax season, with single filers eligible for $19 to $37 depending on adjusted gross income—far below the hundreds returned in prior years. This modest amount reflects a certified $296.1 million surplus from fiscal year 2024-25, but after allocations for property tax exemptions and other statutory requirements, only a limited portion remains for statewide sales tax refunds. The underlying causes trace directly to policy decisions by Democratic leaders and Governor Jared Polis, who have expanded tax credits and programs that divert potential surpluses, compounding external pressures like federal tax changes and exposing persistent failures in fiscal oversight that undermine TABOR’s core purpose of limiting government growth and returning excesses to citizens.
Adopted by voters in 1992 as Article X, Section 20 of the Colorado Constitution, the Taxpayer’s Bill of Rights (TABOR) restricts state and local revenue increases to the rate of inflation plus population growth, mandating voter approval for tax hikes and refunds of any surplus beyond the cap. Referendum C, passed in 2005, adjusted the cap upward to allow retention for priorities like education and health care, yet surpluses above this level must still be refunded. Historically, TABOR has returned over $10 billion to taxpayers, promoting economic discipline but introducing budget instability. In stronger economic periods, such as fiscal year 2022-23 with a $3.6 billion surplus, refunds reached $565 for higher-income single filers. For tax year 2025, claimed on returns filed this spring, the State Controller certified a $296.1 million surplus on September 1, 2025, yielding a $293.3 million refund obligation after minor adjustments. Eligible full-year 2025 Colorado residents—not incarcerated or committed for over 180 days in the prior fiscal year—can claim these via Form DR 0104 or Property Tax/Rent/Heat applications, with amounts tiered by income: $19 for up to $52,000, $25 for $52,001 to $105,000, $29 for $105,001 to $168,000, $35 for $168,001 to $233,000, and $37 for $233,001 to $299,000 (double for joint filers).
The constrained refunds result from a combination of factors, but foremost among them are deliberate expansions of social programs that siphon funds before they can accumulate as surpluses. The Earned Income Tax Credit (EITC) and Family Affordability Tax Credit (FATC), enhanced under House Bills 24-1134 and 24-1311 during Democratic-controlled sessions, distribute over $1 billion annually to lower-income households, effectively reducing the pool available for general refunds. These credits, fully implemented in tax year 2025 but halved or paused in 2026 due to revenue shortfalls, prioritize targeted relief at the expense of broader taxpayer returns, a shift critics from the Common Sense Institute and Independence Institute describe as inefficient, with administrative costs exceeding those of uniform rate reductions. Federal reforms via H.R. 1—the “One Big Beautiful Bill Act”—further erode revenues by $1 billion through expanded deductions and corporate adjustments, pushing fiscal year 2025-26 projections $308.2 million below the Referendum C cap and eliminating refunds for tax year 2026 filings in 2027.
This trajectory reveals entrenched patterns of fiscal mismanagement under Governor Polis and Democratic majorities, who have repeatedly reclassified revenues as fees to sidestep TABOR’s voter-approval requirements, amassing billions for enterprises like transportation without public consent. State audits highlight overruns, including $50 million in behavioral health initiatives and $200 million in Medicaid expansions that exceeded forecasts, while the General Fund swells to $18.2 billion for fiscal year 2025-26 amid priorities favoring $2.4 billion in health care increases and $500 million in education supplements—despite Colorado’s 40th national ranking in teacher pay and lagging infrastructure. Polis’s January 2, 2026, budget amendments acknowledge the bind, halting EITC and FATC expansions for tax year 2026 as a corrective measure, yet this comes after years of expansions that have converted potential $5,119 average household refunds into narrower distributions. Conservative evaluations estimate these tactics could enable $42 billion in net tax increases if unaddressed, diluting accountability and contradicting TABOR’s intent to constrain government and empower taxpayers.
Compounding the issue, economic volatility—exacerbated by reliance on federal aid and inconsistent revenue streams—has flipped multi-billion surpluses to deficits, with no refunds projected for 2027 but a modest $208.2 million surplus anticipated in fiscal year 2026-27. While advocates defend these programs for addressing inequities, outcomes remain uneven: health rankings persist below average despite spending growth, suggesting execution flaws and wasted resources. Polis’s office has cited Pinnacol Assurance’s declining market share as another inefficiency, potentially requiring state subsidies and higher business premiums, further straining budgets.
Ultimately, TABOR endures as a vital check on overreach, but the diminished 2026 refunds underscore how current leadership’s programmatic preferences have favored selective aid over direct rebates, fostering instability and prompting calls for renewed fiscal restraint to restore taxpayer protections.
