Any full-year Colorado resident who was at least 18 by the end of the tax year, is not claimed as a dependent on someone else’s federal return, and was not held in a Colorado correctional facility for 180 days or more that year gets a TABOR refund in Colorado, as long as they file a Colorado individual income tax return or a Property Tax/Rent/Heat Credit application by the October deadline.1Department of Revenue – Taxation. TABOR
The Four Eligibility Conditions
To qualify for the TABOR sales tax refund, you need to meet all four of these at once:
- Full-year Colorado residency. Your primary home must have been in Colorado from January 1 through December 31 of the tax year. Temporary absences for travel or work don’t break residency as long as you intended to return and kept your Colorado home.
- Age 18 or older. You must have turned 18 by December 31 of the tax year.
- Not claimed as a dependent. No one can claim you as a dependent on their federal income tax return for that year.
- Not incarcerated for 180 days or more. Anyone held in a Colorado correctional facility for at least 180 days during the tax year is ineligible.1Department of Revenue – Taxation. TABOR
Who Doesn’t Qualify
Part-year residents and nonresidents are out, even if they filed a Colorado return and paid Colorado tax. If you moved to Colorado partway through the calendar year, you’ll have to wait until you complete a full January-through-December year in the state before you qualify for a refund tied to that year.1Department of Revenue – Taxation. TABOR
College students and young adults claimed as dependents on a parent’s federal return don’t qualify in their own right, no matter how long they lived in Colorado. The dependency test is federal, not based on where you actually lived or who paid your expenses day to day.
Age cuts off the youngest filers. If you turned 18 after December 31 of the tax year, you don’t qualify for that year’s refund even if you earned Colorado income and filed a return.
The 180-day incarceration rule applies specifically to Colorado correctional facilities and to time within the tax year itself. Shorter stays don’t disqualify an otherwise eligible resident.
You Have to File to Get Paid
Eligibility by itself doesn’t trigger a payment. You have to claim the refund by filing either a Colorado Individual Income Tax Return (Form DR 0104) or a Property Tax/Rent/Heat Credit Rebate Application (Form DR 0104PTC). This applies even if you had no income and owe no state tax. Without a return on file, there’s no refund.1Department of Revenue – Taxation. TABOR
Most eligible residents use Form DR 0104. The TABOR refund is claimed on a designated line within the return; no separate schedule is needed. The Department of Revenue offers free electronic filing through its Revenue Online portal.2Department of Revenue – Taxation. File Individual Income Tax Online
The PTC Alternative for Older and Low-Income Residents
If you’re 65 or older, or a surviving spouse age 58 or older, and your income falls below the PTC thresholds, you can claim your TABOR refund through the PTC application instead of a full income tax return. For the 2025 tax year, the income limits are $19,094 for single filers and $25,788 for joint filers. Residents without a Social Security Number or ITIN can apply using an alternate identification number through Form DR 0019.3Department of Revenue – Taxation.

The Deadline That Actually Matters
For the TABOR refund, the deadline is October 15 of the year after the tax year, not April 15. Colorado automatically grants a six-month filing extension past the April date, so you don’t need to request one.4Department of Revenue – Taxation. Individual Income Tax Due Dates and Filing Extension One caveat: the extension is for filing, not for paying. If you owe state tax, interest runs from April 15 regardless. If your only reason to file is the TABOR refund and you have no tax liability, October 15 is your real cutoff. Miss it, and the refund for that year is gone.5Justia Law.

Claiming for a Resident Who Died During the Year
A Colorado resident who met the eligibility requirements but died during the tax year still has a refund to claim. A surviving spouse or legal representative can file for it using Form DR 0104 along with Form DR 0102 (Claim for Refund on Behalf of a Deceased Taxpayer) and a copy of the death certificate.6Department of Revenue – Taxation. Deceased Taxpayer
A surviving spouse writes “DECEASED” in large letters above the tax year on the return and notes “filing as a surviving spouse” in the decedent’s signature block. A legal representative does the same but writes “filing as a legal representative” and completes the Third Party Designee section. When filing electronically, the death certificate and Form DR 0102 go through the e-Filer Attachment feature on Revenue Online.6Department of Revenue – Taxation. Deceased Taxpayer
When an Eligible Person’s Refund Gets Intercepted
Qualifying doesn’t guarantee the money reaches you. Colorado’s refund intercept program applies to all state tax refunds, including the TABOR sales tax refund. The state can seize it to cover:7Colorado Department of Revenue. General 17 – Refund Interceptions
- Unpaid child support or overpaid public assistance benefits
- Back state taxes owed to the Department of Revenue
- Federal tax debts certified by the IRS
- Court-ordered fines, fees, or restitution
- Unpaid student loans from state-supported institutions or CollegeInvest
- Unemployment compensation fund debts
- Other state agency debts certified by the State Controller
Before an interception, you should receive a written notice at your last known address explaining the debt and your right to dispute it. You have 30 days from the mailing date of that notice to request an administrative review or an evidentiary conference. You can contest whether the debt amount is correct or whether the debt belongs to you, but you cannot contest the existence of the interception mechanism itself.8Justia Law.
