Colorado Wildfire Mitigation Tax Credit: The 2026 Guide

How do the wildfire mitigation tax credits work in Colorado?

Source: Colorado Department of Revenue, Income Tax Topics: Wildfire Mitigation Measures. Income limits are federal taxable income and adjust annually for inflation; the Department publishes each year's limit after year end.

Three rules shape the credit. It is nonrefundable: it can reduce your Colorado income tax to zero, but any excess is not refunded. It cannot be carried forward to future years. And it is per return: joint filers share one annual maximum, and for property owned by tenants in common or joint tenants, only one owner may claim it. The credit is scheduled for repeal effective January 1, 2030, with the final claimable year being tax year 2027.

What work qualifies for the credit?

That list maps directly onto professional mitigation work: defensible space creation, hazard tree and fuels removal, and slash treatment. Timberline performs all mitigation work to Colorado State Forest Service defensible space standards and Home Ignition Zone guidelines and NFPA 1144. Our invoices and post-completion documentation itemize the mitigation measures performed and the amounts paid, which is the documentation format the credit's receipt requirement calls for.

What costs do NOT qualify?

Two of these exclusions matter most in practice. First, if you split mitigation costs with neighbors or received grant or cost-share funding, the shared or reimbursed portion does not qualify, but per the State Auditor's 2026 review of the program, the portion you paid out of pocket and were not reimbursed for can still qualify. Cost-share reimbursement typically runs directly between you and the program, so keep your award or reimbursement records alongside our invoice: the invoice documents what you paid us, the program records document what was reimbursed, and the difference is the out-of-pocket amount the credit is calculated on. Second, because inspection and certification fees are excluded, a standalone forest health assessment fee likely does not qualify for the credit, while the mitigation work that follows it does. Confirm treatment of any specific expense with your tax professional.

How do I claim the credit?

1. Keep every receipt. The credit requires actual out-of-pocket expenses paid to a third-party provider, documented by receipt.
2. Complete the Individual Credit Schedule (form DR 0104CR) and file it with your Colorado Individual Income Tax Return (DR 0104).
3. Submit copies of your receipts, either with your return or through the E-Filer Attachment function at Colorado.gov/RevenueOnline.
4. Check the year's income limit. For 2025 it is $129,200 in federal taxable income; the 2026 limit is published by the Department of Revenue after year end.

Timberline customers automatically receive a copy of their invoice at payment and a post-completion document when the work is finished. Keep both with your tax records; together they document what was done and what you paid.

What happened to the old wildfire mitigation subtraction?

One historical note for anyone amending a past return: for tax years 2023 and 2024, the Department of Revenue confirms a taxpayer meeting all requirements could claim both the subtraction and the credit for the same year's qualifying costs. Talk to your tax professional before amending.

What other wildfire mitigation assistance exists in our area?

Several verified programs help homeowners in our region pay for mitigation. As of mid-2026 (funding availability changes, so confirm directly with each organization):

Wildfire Adapted Partnership (wildfireadapted.org), serving Archuleta, La Plata, Montezuma, San Juan, and Dolores counties, offers free wildfire risk site visits, a Chipper Rebate Program that reimburses individuals 50% of chipping costs up to $250 (communities up to $1,500), and a Community Mitigation Grant Program that funds neighborhood-scale projects through active neighborhood ambassadors with at least a 25% cash match, with completed projects inspected by WAP and the Colorado State Forest Service. Chipping, notably, is one of the secondary fuel treatments named in the tax credit statute, so the rebate and the credit intersect directly: the reimbursed portion of a chipping bill does not qualify for the credit, and your unreimbursed share can.

For Rio Grande, Mineral, and the other San Luis Valley counties, Colorado State Forest Service district offices are the starting point for what is currently funded. At the community scale, the CSFS Forest Restoration and Wildfire Risk Mitigation (FRWRM) grant program funded projects in counties including Alamosa, Archuleta, Conejos, Costilla, Mineral, Rio Grande, and Saguache in its spring 2026 cycle, with the next round announced in fall 2026; FRWRM funds communities and groups rather than individual homeowners, and it is the program behind much of the organized mitigation work in the region. At the state scale, the Colorado Strategic Wildfire Action Program (COSWAP), a permanent program in the Department of Natural Resources, funds landscape-scale mitigation projects and mitigation workforce crews statewide; like FRWRM, it funds projects and organizations rather than individual homeowners.

The interaction rule applies to all of it: amounts a program reimburses do not qualify for the tax credit, but your unreimbursed out-of-pocket share can. Used together, cost-share plus the credit can meaningfully reduce the net cost of a mitigation project. And separately from taxes, documented mitigation now carries insurance value under Colorado HB 25-1182; see our Wildfire Insurance Documentation guide.
