Colorado offers a state R&D tax credit for businesses that increase their research and development spending and operate within designated Enterprise Zones. When paired with the federal credit, qualifying Colorado businesses can reduce innovation costs at both the state and federal level.
Colorado R&D Tax Incentives at a Glance
Excelsior Jobs Program R&D Credit:
- Credit based on the increase in qualified research expenses compared to a two-year average baseline
- Applies only to research conducted within a designated Colorado Enterprise Zone
- Non-refundable; offsets Colorado state income tax liability, with unused credit carried forward until it is used
- Requires certification through the state's economic development office before and after the tax year
- Open to both new and existing businesses with no industry restrictions
Federal Benefits:
- Available for all qualifying U.S. research
- Payroll tax offset option for eligible startups
- Stackable with Colorado's state credit on the same qualifying expenses
Key Distinctions:
- Colorado's R&D credit is not available statewide. Research must be conducted within one of Colorado's designated Enterprise Zones, which are economically distressed areas identified by the state. Confirming your business location falls within a zone is the first step in determining eligibility.
- The credit is not all usable in the year it is generated. The credit is effectively broken into four equal installments: 25% can be claimed in the year of the expenditure, and 25% in each of the three following years, subject to tax liability. In any year, you generally cannot use more than 25% of the original credit amount from a given credit year; unused portions carry forward.
Who Qualifies for Colorado's Enterprise Zone R&D Tax Credit?
What Research Activities Qualify in Colorado?
Colorado uses the same federal standards to define qualifying research, so if your work holds up under the federal four-part test, it will generally qualify at the state level too. The key difference in Colorado is geographic: the work has to happen inside a designated Enterprise Zone, not just anywhere in the state.
In practical terms, that means the questions your team is asking during a credit review shift slightly. It's not just "does this activity qualify?" but also "where was this activity performed?" For businesses with employees or contractors working across multiple locations, tracking the physical location of research activities and associated costs is an important part of building a supportable claim.
What Expenses Qualify for Colorado's R&D Tax Credit?
Wages and Salaries
Employees directly conducting, supervising, or supporting qualified research within an Enterprise Zone
Supplies
Materials consumed during the research process within an Enterprise Zone
Contract Research
Amounts paid to third parties performing qualified research within an Enterprise Zone
Colorado generally follows the federal definition of qualified research expenses, limited to costs tied to work performed within a designated Enterprise Zone.

Federal R&D Tax Credit for Colorado Businesses
The federal credit can be calculated using the Regular Research Credit (RRC) or the Alternative Simplified Credit (ASC), a streamlined method often preferred by newer claimants. Qualified small businesses may also be able to apply the credit against payroll taxes, which can generate a meaningful cash benefit even for companies with limited income tax liability. Businesses should work with a qualified tax advisor to evaluate which calculation method and elections make the most sense given their situation.

Saving Money, Spurring Innovation
Every day, companies nationwide further the mission of innovation with new products, processes and initiatives that change the landscape of how we do business. But innovation takes funding, and with that comes a vicious cycle: You need money to grow your business and develop your products and services… but you also need to do those same things to bring money in.
That’s why R&D tax credits were established. Designed to encourage companies like yours to invest in the innovation, creation and improvement of products or processes, R&D tax credits can offset some of the costs associated with research and development — fueling growth and technological advancement.
Pitfalls Colorado Businesses Should Avoid
Can You Claim Credits for Previous Years in Colorado?
Colorado's state R&D credit requires pre-certification before activity begins, which means prior years generally cannot be captured retroactively through the state program.
However, the federal R&D credit remains available on amended returns for open tax years within the applicable statute of limitations. Many Colorado businesses in qualifying industries have significant unclaimed federal credits available through amended returns, particularly those that have been conducting qualifying research for years without realizing it.
A professional review can identify available federal credits across open years, evaluate whether your business qualifies for Colorado's Enterprise Zone program going forward and put the right documentation and pre-certification processes in place for future claims.
