TABOR refunds are not sales tax refunds—they're money Colorado returns when the state collects more tax revenue than the law allows it to keep

A TABOR refund is a payment from the state of Colorado to individual taxpayers when state revenue exceeds the limit set by the Taxpayer Bill of Rights (TABOR). The refund comes from income tax, sales tax, and other state revenue combined—not from sales tax alone. Colorado's TABOR law, passed in 1992, caps how much revenue the state can retain each year. When actual revenue surpasses that cap, the excess must be returned to taxpayers.

The confusion happens because the refund amount is calculated using total state revenue, which includes sales tax collections. But you're not getting back the sales tax you personally paid. Instead, you're receiving a share of the overall surplus the state collected across all revenue sources. The refund is distributed based on your income tax liability for that year, not on what you spent.

Key Takeaways

  • TABOR refunds come from overall state revenue surplus, not specifically from sales tax you paid.
  • The refund amount is based on your income tax liability, not your spending or sales tax payments.
  • Colorado must return the money when total state revenue exceeds the TABOR spending limit for that year.
  • Refunds are issued automatically to people who filed a Colorado income tax return; you do not need to request one separately.
  • The refund appears as a credit on your state tax return or as a separate check, depending on the year and how you filed.

How the TABOR limit actually works

TABOR sets a ceiling on how much revenue Colorado can spend in a given year. The limit is based on the prior year's revenue, adjusted for inflation and population growth. If the state collects more money than this formula allows, the excess is considered a "surplus" that must be refunded.

The state does not separate which revenue came from sales tax versus income tax versus other sources when calculating the surplus. All revenue flows into one pool. When that pool exceeds the limit, the entire surplus gets refunded proportionally to taxpayers based on their income tax liability. This is why a TABOR refund is not the same as a sales tax refund—it's a share of the total overage, distributed through the income tax system.

Who receives a TABOR refund and when

Anyone who filed a Colorado income tax return for the year in question is may have access to to a share of the refund. You do not need to take any action to receive it. The state automatically processes TABOR refunds for all may be able to access filers.

The timing varies by year. Some years Colorado has no surplus and no refund is issued. Other years the surplus is large enough to trigger a refund. When a refund is due, the state typically issues it in the fall or winter following the tax year. For example, a 2023 surplus would be refunded in late 2024 or early 2025. The refund may appear as a credit applied to your 2024 tax return, or as a separate check mailed to you, depending on how the state processes it that year.

The difference between TABOR refunds and sales tax refunds

A sales tax refund would return the specific sales tax you paid at the register. Colorado does not issue those. Instead, TABOR refunds are a mechanism to prevent the state from accumulating excess revenue—they're a constitutional requirement, not a consumer benefit program.

If you want to reduce the sales tax you pay going forward, that requires a change to Colorado's sales tax rate itself, which is set by law and varies by county and city. A TABOR refund does not change those rates. It straightforward returns money the state collected but was not allowed to keep under the TABOR formula.

How much you receive depends on your income tax liability

The state divides the total surplus by the total income tax liability across all Colorado filers, then multiplies your individual income tax liability by that percentage. This means higher earners receive larger refunds in dollar terms, because they have higher income tax liability. A person who paid $5,000 in Colorado income tax will receive a larger refund than someone who paid $500, even if both lived in the same county and paid the same sales tax rate.

The refund is not based on how much you spent, where you shopped, or what sales tax rate applied in your area. It is purely a function of your income tax obligation for that year.

What happens if you did not file a Colorado income tax return

If you lived in Colorado but did not file a state income tax return, you would not automatically receive a TABOR refund. Colorado residents with income below the filing threshold are not required to file. However, some of these people may still be may have access to to a refund if they had tax withheld or paid estimated taxes.

If you think you should have filed or should have received a refund, contact the Colorado Department of Revenue. They can review your situation and determine whether you are owed money. The state sometimes extends the important date to claim unclaimed refunds, but waiting too long can result in forfeiture.

TABOR refunds versus other Colorado tax credits

Colorado offers other tax credits and refunds separate from TABOR—such as the Earned Income Tax Credit (EITC), property tax exemptions, and senior homeowner property tax deferral. These are different programs with different rules and may be able to access requirements. A TABOR refund is automatic and based solely on the state's revenue surplus. Other credits require you to meet specific conditions and often require you to claim them on your return.

If you received a TABOR refund and also received other credits or refunds, those are separate transactions. The TABOR refund is not reduced by other credits, and other credits are not affected by TABOR.

Frequently Asked Questions

Can I claim a TABOR refund if I moved out of Colorado?

You can receive a refund for the year you lived in Colorado and filed a return there. If you moved out partway through the year, you may still be may have access to to a refund based on the income tax you paid while a resident. Contact the Colorado Department of Revenue if your situation is unclear.

What if I did not receive my TABOR refund?

Check your 2024 tax return to see if the refund was applied as a credit rather than issued as a separate payment. If you cannot find it, contact the Colorado Department of Revenue with your Social Security number and the tax year in question. They can confirm whether a refund was issued and where it was sent.

Is the TABOR refund taxable income?

No. TABOR refunds are not considered income and are not subject to federal or state income tax. You do not report them on your federal return, and they do not affect your federal tax liability.

Why does the refund amount change from year to year?

The refund depends on how much surplus the state collected that year. Some years revenue exceeds the TABOR limit by a small amount; other years by a large amount. Years with strong economic growth and high sales may produce larger refunds. Years with slower growth may produce smaller refunds or no refund at all.
