What a TABOR refund is and why Colorado sends them

A TABOR refund is money Colorado returns to taxpayers when the state collects more tax revenue than a constitutional limit allows it to keep. TABOR stands for Taxpayer Bill of Rights, a 1992 amendment that caps how much revenue Colorado can retain each year. When actual revenue exceeds that cap, the state must return the overage to taxpayers rather than spend it or save it.

The refund is not a tax credit you claim on a return. It is a direct payment the state sends to you based on your prior-year tax filing. Colorado calculates how much each household owes in refunds, then distributes the money through the mail or direct deposit, depending on how you filed.

TABOR refunds are irregular. Some years Colorado collects enough extra revenue to trigger a refund; other years it does not. The amount you receive varies based on your tax liability and the total overage the state collected. A household that paid $5,000 in state income tax receives a larger refund than one that paid $1,000, because the refund is distributed proportionally.

Key Takeaways

  • TABOR refunds happen when Colorado collects more tax revenue than its constitutional limit allows, and the state must return the excess to taxpayers.
  • The refund is calculated based on your prior-year Colorado income tax liability, so households that paid more tax receive larger refunds.
  • Colorado sends TABOR refunds by check or direct deposit to the address or account on file from your most recent tax return.
  • Refunds are not automatic claims—the state identifies who is owed money and initiates the payment without requiring you to take action.
  • The timing and amount of TABOR refunds vary year to year depending on how much revenue the state collects above the constitutional cap.

How Colorado calculates your refund amount

Colorado divides the total refund pool by the total state income tax collected in the prior year, then multiplies that percentage by what you personally paid in state income tax. If the state collected $100 million in excess revenue and total state income tax was $10 billion, the refund rate is 1 percent. A household that paid $5,000 in state income tax receives $50.

The state uses your Colorado income tax return from the prior calendar year to determine your tax liability. If you filed a joint return, both spouses are listed on the refund check or deposit. If you filed as head of household or single, only your name appears. Dependents do not receive separate refunds.

Colorado does not refund money to households that paid no state income tax. You must have had a tax liability in the prior year to receive a TABOR refund. This includes people who had taxes withheld from paychecks but owed nothing after filing, because the withholding counts as your tax liability for that year.

When Colorado sends TABOR refunds and how you receive them

The state typically announces TABOR refunds in late spring or early summer, after the prior fiscal year closes and revenue is final. Refunds are usually mailed or deposited between June and September, though the exact timing varies. Colorado's Department of Revenue publishes a schedule on its website when a refund is confirmed.

If you filed your prior-year return electronically and provided direct deposit information, Colorado deposits your refund to that account. If you filed on paper or did not authorize direct deposit, the state mails a check to the address on your return. Checks are sent in batches, so not all refunds arrive on the same date.

You do not need to do anything to receive a TABOR refund. The state identifies who is owed money based on tax records it already has. If your address or banking information has changed since you filed, update it with the Department of Revenue before the refund is sent, or the check may be mailed to an old address.

TABOR refunds versus other Colorado tax credits and deductions

A TABOR refund is separate from tax credits you claim on your return, such as the Colorado child dependent care credit or the earned income tax credit. Those credits reduce what you owe when you file. A TABOR refund is money the state sends back after the year is over, because it collected too much overall.

TABOR refunds also differ from property tax refunds or sales tax refunds, which are separate programs. Some Colorado counties and municipalities offer property tax relief or refunds under different rules. The TABOR refund applies only to state income tax overage.

If you received a TABOR refund in a prior year, that does not mean you will receive one the following year. The refund depends entirely on whether the state collects excess revenue that year. A year with strong economic growth and high tax collection may trigger a refund; a slower year may not.

What to do if you did not receive your TABOR refund

If Colorado announced a TABOR refund but you did not receive it, first check whether you had a tax liability in the prior year. You must have filed a Colorado income tax return and owed tax (or had tax withheld) to be included. If you did not file or owed nothing, you are not owed a refund.

If you believe you should have received a refund, contact the Colorado Department of Revenue. Provide your Social Security number and the tax year in question. The department can confirm whether a refund was issued, when it was sent, and to which address or account. If a check was mailed to an old address, the department may be able to issue a replacement.

Refund checks that are not cashed within a certain period may be voided. If your check was lost or damaged, contact the Department of Revenue to request a replacement. Direct deposit refunds that fail due to a closed account or incorrect routing number are typically returned to the state; you will need to contact the department to arrange reissue.

How TABOR limits work and why refunds happen

Colorado's TABOR amendment limits how much revenue the state can retain each year. The cap is based on the prior year's revenue, adjusted for inflation and population growth. If actual revenue comes in higher than the cap allows, the excess must be returned to taxpayers or held in a reserve account, depending on state law at the time.

Refunds are triggered by strong tax collection—typically from economic growth, higher wages, increased sales, or one-time revenue sources. A recession or economic slowdown reduces tax collection and may mean no refund that year. The state cannot predict refunds in advance because revenue depends on factors outside its control.

Colorado has issued TABOR refunds in some years and not in others. The amount and frequency are not may provide. Understanding that refunds are irregular helps you avoid counting on them as part of your annual budget.

Frequently Asked Questions

Do I have to report my TABOR refund as income on my federal tax return?

No. TABOR refunds are not considered taxable income for federal purposes. The IRS treats them as a return of tax paid, not as new income. You do not report the refund on your federal return or include it in your adjusted gross income.

What if I moved to another state after filing my Colorado return?

If you moved before the refund was sent, update your address with the Colorado Department of Revenue. The state will mail the check to your new address if you provide it in time. If the check was already mailed to your old address, contact the department with your new address and they can help locate or reissue it.

Can I claim a TABOR refund I did not receive on my next year's Colorado tax return?

No. TABOR refunds are not claimed on tax returns. If you did not receive a refund you believe you were owed, contact the Colorado Department of Revenue directly. They can investigate whether a refund was issued and help you obtain a replacement if it was lost or misdirected.

Is a TABOR refund the same as getting money back from my tax withholding?

No. A tax refund from your annual return is money you overpaid in withholding during the year. A TABOR refund is separate—it is money Colorado returns because the state collected more tax revenue than the constitution allows it to keep. You can receive both in the same year.

How do I know if a TABOR refund is coming this year?

The Colorado Department of Revenue announces TABOR refunds after the fiscal year closes and revenue is final. Check the department's website or news releases in late spring or early summer for confirmation. The announcement will include the refund rate and when payments will be sent.
