Colorado's heat pump tax credits drop from $1,500 to $750 in 2026 due to budget shortfalls. Denver homeowners: install before December 31, 2025 to maximize savings.
Colorado Heat Pump Tax Credits Are Getting Slashed – Here's What Denver Homeowners Need to Know
If you've been thinking about upgrading to a heat pump for your Denver home, the clock is ticking. Colorado's generous heat pump tax credits—which have been helping homeowners save up to $1,500 on installations—are being cut in half starting January 1, 2026.
This sudden change comes from the state's dismal revenue forecast announced in June 2025. Colorado economists project only 2% revenue growth for next year, falling well short of the 4% threshold needed to keep the full green tax credits intact. For homeowners across Aurora, Lakewood, Westminster, and throughout the Front Range, this means a dramatic reduction in available savings for energy-efficient heating and cooling upgrades.
The good news? You still have time to lock in the maximum savings—but you need to act before the end of 2025.
How Much Are the Tax Credits Being Reduced?
The cuts are significant and affect all types of heat pump installations. Here's the breakdown of what's changing on January 1, 2026:
Air-Source Heat Pumps (Space Heating/Cooling)
2024-2025: $1,500 tax credit
2026-2028: $750 tax credit (50% reduction)
2029-2032: Drops further to $500
Ground-Source (Geothermal) Heat Pumps
2024-2025: $3,000 tax credit
2026-2028: $1,500 tax credit (50% reduction)
2029-2032: Drops further to $1,000
Heat Pump Water Heaters
2024-2025: $500 tax credit
2026-2028: $250 tax credit (50% reduction)
2029-2032: Remains at $250
For a Denver homeowner installing a standard air-source heat pump, this reduction means losing $750 in savings simply by waiting until next year. That's not pocket change—it's a significant portion of your installation cost.
Why Are Colorado's Green Tax Credits Being Cut?
The reduction comes down to simple economics. When Colorado lawmakers enacted these green tax credits in 2023 through HB23-1272, they included a safeguard provision: the credits maintain full value only when the state projects at least 4% revenue growth for the following fiscal year. If growth falls below that threshold, the credits automatically get cut in half.
As recently as March 2025, state economists projected the tax credits would remain intact. However, by June, "lower collections and a reduction in expectations for the economy" changed everything. With projected revenue growth at only 2%—half the required threshold—the automatic cuts were triggered.
Emily Dohrman, senior economist for the nonpartisan Legislative Council Staff, explained the situation at a Joint Budget Committee meeting: the state simply doesn't have the revenue to support the full credit amounts alongside other budget priorities.
The Perfect Storm: Federal Incentives Are Also Expiring
The timing couldn't be worse for Denver homeowners planning heat pump installations. Not only are state credits being slashed, but federal incentives are also disappearing at the end of 2025.
Federal Tax Credits Ending December 31, 2025:
Energy Efficient Home Improvement Credit (25C):
30% of installation costs, capped at $2,000 for air-source heat pumps
Previously expected to last into the 2030s
Moved up end date due to the "One Big Beautiful Bill Act" signed July 2025
Expires completely after December 31, 2025
Renewable Energy Tax Credit (25D):
30% of total system cost with no cap for geothermal heat pumps
Also expires December 31, 2025
This means homeowners who install before year-end can stack both state AND federal credits for maximum savings. Wait until 2026, and you'll lose both the full state credit and all federal incentives—potentially missing out on thousands of dollars in combined savings.
What This Means for Your Heat Pump Installation Budget
Let's look at real numbers to understand the financial impact for Denver homeowners considering a heat pump upgrade:
Example: Standard Air-Source Heat Pump Installation
Typical Installation Cost: $8,000 - $12,000
If You Install in 2025:
Federal Tax Credit (25C): Up to $2,000
Colorado State Tax Credit: $1,500
Xcel Energy Rebate: $2,200 (for cold-climate models)
Total Potential Savings: Up to $5,700
Your Net Cost: $2,300 - $6,300
If You Wait Until 2026:
Federal Tax Credit (25C): $0 (expired)
Colorado State Tax Credit: $750 (reduced)
Xcel Energy Rebate: $2,200 (for cold-climate models)
Total Potential Savings: $2,950
Your Net Cost: $5,050 - $9,050
The Difference? Waiting until 2026 could cost you $2,750 more for the exact same heat pump installation. That's nearly double the net cost for homeowners in Westminster, Thornton, and throughout the Denver Metro Area.
How the Colorado Heat Pump Tax Credit Actually Works
Understanding how to claim this credit is important, especially since it works differently than you might expect. The Colorado heat pump tax credit is claimed by the installing contractor, who then passes the savings to you as an upfront discount at the time of installation.
Key Requirements:
Must Use a Registered Contractor: Your contractor must be registered with the Colorado Energy Office to claim the credit on your behalf
Upfront Discount: You receive at least 33.33% of the tax credit as an immediate discount on your invoice
Must Meet 80% of Heating Needs: Heat pumps for space heating must cover at least 80% of your home's annual heating requirements
Energy Star Certified: All heat pumps must be Energy Star certified
Proper Documentation: The discount must appear on your invoice as "State of Colorado Heat Pump Discount"
Important: You don't file any paperwork for the Colorado state credit—your registered contractor handles everything. This makes it incredibly easy to claim your savings when you work with qualified HVAC services in Denver like MoJo Home Services.
Can You Still Stack Multiple Incentives?
Yes! The Colorado heat pump tax credit can be combined with other incentives, which is why acting before December 31, 2025 is so critical. Here's what you can potentially stack:
Available Incentives to Combine (Through End of 2025):
Federal Tax Credit (25C): Up to $2,000 (expires 12/31/25)
Colorado State Tax Credit: $500-$3,000 depending on system type (reduced 50% in 2026)
Xcel Energy Rebates:
$2,200 for cold-climate heat pumps
$1,700 for other qualifying air-source heat pumps
Local Utility Rebates: Additional savings from your local utility provider
City/County Programs: Denver CARe program and other local incentives (when available)
For homeowners in Littleton and across the Denver Metro Area, stacking these incentives can reduce your heat pump installation cost by 40-60%. But this incredible opportunity disappears after December 31, 2025.
Why Heat Pumps Make Sense for Denver Homes
Beyond the financial incentives, heat pumps are an smart investment for Colorado's climate. Modern cold-climate heat pumps are specifically engineered to handle Denver's temperature extremes efficiently.
Benefits for Denver Homeowners:
All-Season Comfort: One system provides both heating in winter and cooling in summer
Energy Efficiency: Heat pumps are 2-3x more efficient than traditional furnaces
Lower Utility Bills: Save 30-50% on heating and cooling costs compared to separate furnace and AC
Environmentally Friendly: Significantly reduce your home's carbon footprint
Works in Colorado Cold: Modern systems operate efficiently even when temps drop to -15°F or lower
Improved Air Quality: No combustion means no carbon monoxide risk and better indoor air
Consistent Heating: No temperature swings like traditional furnaces
What Happens If You Miss the December 31, 2025 Deadline?
If you're unable to complete your heat pump installation before the end of 2025, you'll still have access to incentives—just significantly reduced ones. Here's what will still be available starting January 1, 2026:
Remaining Incentives in 2026:
Reduced Colorado State Credit: $250-$1,500 (50% of current amounts)
Xcel Energy Rebates: Still available at current levels
Local Utility Programs: May still be available depending on your provider
Federal IRA HEAR/HOMES Rebates: Income-qualified rebates launching in late 2025/early 2026
The new federal HEAR (Home Electrification and Appliance Rebates) and HOMES (Home Efficiency Rebates) programs will provide some relief for income-qualified homeowners in 2026. However, these rebates are limited to households earning 150% or less of Area Median Income and won't replace the generous incentives available through the end of 2025 for all homeowners.
5 Steps to Maximize Your Heat Pump Savings Before Year-End
If you want to take advantage of the full tax credits before they're cut, here's your action plan:
1. Act Immediately – Don't Wait for "Perfect Timing"
HVAC contractors are experiencing increased demand as word spreads about the deadline. Scheduling gets tighter as we approach winter, and December installations become challenging. The time to act is now.
2. Get Multiple Quotes from Registered Contractors
Verify that contractors are registered with the Colorado Energy Office to claim the heat pump tax credit. Ask specifically how they'll apply the "State of Colorado Heat Pump Discount" to your invoice. Not all contractors are registered, and unregistered contractors cannot pass the state credit to you.
3. Confirm Your Installation Can Be Completed by December 31
The equipment must be installed and placed in service by December 31, 2025 to qualify for both federal and full state credits. Simply ordering equipment isn't enough—the installation must be complete.
4. Understand Your Home's Heating Needs
For the Colorado credit, your heat pump must meet at least 80% of your annual heating needs. A qualified contractor can perform a load calculation to ensure proper sizing and compliance.
5. Ask About All Available Rebates and Financing
Make sure your contractor helps you identify and apply for all available incentives: federal credits, state credits, Xcel Energy rebates, and any local programs. Also ask about financing options to make the upfront cost more manageable.
Common Questions About the Tax Credit Reduction
Will the tax credits be restored in future years?
Possibly, but there's no guarantee. The credits automatically return to full value if state revenue growth exceeds 4% in future fiscal years. However, given current economic conditions and the further scheduled reductions in 2029, it's unlikely credits will return to 2025 levels anytime soon.
Can I still claim the federal credit if I install in January 2026?
No. Federal tax credits for heat pumps under the Energy Efficient Home Improvement Credit (25C) expire permanently on December 31, 2025. There is no extension—the system must be installed and placed in service by that date.
What if my contractor can't complete installation before December 31?
Unfortunately, you'll only qualify for the reduced state credit and no federal credit. This is why scheduling immediately is crucial. Some contractors are already booking into late December.
Do the reduced credits also affect commercial installations?
Yes. The Colorado state heat pump tax credit applies to residential and commercial installations. Commercial buildings can claim one credit per 4 tons of installed capacity (up to 100 tons per building), and these amounts will also be cut in half in 2026.

Frequently Asked Questions
Why does my contractor claim the Colorado heat pump tax credit instead of me filing for it myself?
Colorado's heat pump tax credit works differently from most tax benefits homeowners are familiar with. Rather than filing a form at tax time, the credit is claimed directly by your installing contractor — but only if they are registered with the Colorado Energy Office. The contractor passes at least 33.33% of the credit value to you as an upfront discount on your invoice, which must appear as "State of Colorado Heat Pump Discount." This means choosing an unregistered contractor isn't just a technicality — it means you forfeit the state credit entirely, with no way to claim it yourself afterward.
What does it mean for a heat pump to cover 80% of my home's annual heating needs?
The 80% requirement is a qualification condition for the Colorado state credit — your heat pump must be sized and installed to handle the majority of your home's heating demand rather than serve purely as a supplemental system. A qualified contractor determines this through a proper load calculation that accounts for your home's size, insulation, and local climate data. In Denver's climate, most properly sized cold-climate heat pumps will naturally meet this threshold. If you're using a dual-fuel setup where a gas furnace handles extreme cold backup, your contractor should confirm the heat pump's percentage contribution qualifies before applying the credit.
How does the federal 25C Energy Efficient Home Improvement Credit work for heat pumps?
The 25C credit covers 30% of your qualified heat pump installation costs, capped at $2,000 for air-source heat pumps. Unlike the Colorado state credit which your contractor claims on your behalf, the federal 25C credit is claimed directly by you on your federal income tax return for the year the system was installed and placed in service. The equipment must meet specific efficiency standards to qualify, and your contractor should be able to confirm whether the system they're proposing meets the requirements. Since this credit expires permanently on December 31, 2025, the installation must be complete — not just ordered — before that date.
What is the Xcel Energy cold-climate heat pump rebate and how do I qualify?
Xcel Energy offers a $2,200 rebate specifically for cold-climate heat pump models — those engineered to operate efficiently in sub-zero temperatures, which makes them particularly well-suited for Denver's winters. Standard air-source heat pump installations qualify for a $1,700 rebate. Unlike the state and federal credits, Xcel rebates are not tied to the December 31, 2025 deadline and should remain available into 2026. However, the rebate alone won't offset the loss of the full state and federal credits — homeowners who qualify for all three incentives simultaneously in 2025 can save up to $5,700, compared to roughly $2,950 if they wait until 2026.
What are the HEAR and HOMES federal rebate programs and will they replace the expiring credits?
HEAR (Home Electrification and Appliance Rebates) and HOMES (Home Efficiency Rebates) are federally funded programs launching in late 2025 and into 2026. They provide point-of-sale rebates for heat pumps and other efficiency upgrades — but with a significant limitation: eligibility is restricted to households earning 150% or less of the Area Median Income for their area. For Denver-area homeowners above that income threshold, these programs offer no benefit and will not replace the broad-based federal 25C credit that expires at year-end. For income-qualifying households, HEAR rebates can be substantial, but they are a different and narrower program than the universal credits expiring in 2025.
Why are heat pumps 2-3 times more efficient than a traditional furnace?
The efficiency advantage comes from a fundamental difference in how the two systems work. A furnace generates heat by burning fuel — even a 98% AFUE furnace converts at most 98 cents of every dollar of fuel into warmth. A heat pump doesn't generate heat at all; it moves existing heat from the outdoor air into your home using a refrigerant cycle. Moving heat requires far less energy than creating it, which is why heat pumps can deliver two to three units of heating energy for every one unit of electricity consumed. That ratio — called the Coefficient of Performance — is what makes heat pumps significantly cheaper to operate than combustion-based systems despite electricity typically costing more per BTU than natural gas.
What triggers the automatic restoration of Colorado's full heat pump tax credits in future years?
Colorado's HB23-1272 included an automatic mechanism tied to state revenue projections. The credits return to full value in any year where the state projects revenue growth of at least 4% for the following fiscal year. The same provision that cut them for 2026 — projected growth falling to 2%, below the 4% threshold — works in reverse when economic conditions improve. However, the credits are also scheduled to drop again in 2029 to a third tier of even lower values regardless of revenue performance, meaning a return to 2025 credit levels would require not just economic recovery but potentially new legislative action to extend the current structure.
Can I combine the Colorado heat pump credit with a Denver CARe program benefit if both are available?
Yes — Colorado's state heat pump tax credit can be stacked with local utility and city programs, including the Denver CARe program when available. The key is that each incentive has its own eligibility requirements, application process, and timing. Your contractor should be familiar with which programs are currently active and applicable to your installation. The most important step is confirming your contractor is registered with the Colorado Energy Office for the state credit, as that's the qualification that unlocks the largest single benefit — and the one that disappears at half value on January 1, 2026.
