Solar Incentives in Colorado (2026)

Colorado residents installing rooftop solar can combine the 30% federal Investment Tax Credit (ITC) with a state-specific credit (None (state tax credit removed 2019)). Net-metering rules and property/sales tax exemptions are the other big levers.

Gross install cost (6 kW)$18,000
After federal ITC (30%)$12,600

Colorado avg installed cost: $3.00/watt (state avg, 2026). Federal ITC value: $5,400. Additional state incentives (below) may reduce net cost further.

1. Federal Investment Tax Credit (ITC)

Every U.S. state gets the 30% federal ITC. It applies to the gross install cost, including panels, inverters, labor, and permit fees. For a 6.0 kW system in Colorado at $3.00/watt, that’s a credit of $5,400 against your federal income tax. The credit is refundable-carryforward — unused portions roll to future tax years. Valid through 2032.

2. State income-tax credit

None (state tax credit removed 2019)

This stacks on top of the federal credit. Consult a local CPA to confirm current-year limits.

3. Net metering rules in Colorado

Yes for systems <120% of annual use

Net metering determines how much you’re credited for excess solar energy exported to the grid. "1:1" or "full retail" is the best — you get the same rate you pay. "Avoided cost" or "net billing" pays substantially less (often 25-50% of retail).

4. Property & sales tax exemptions

  • Property tax: ✅ Yes — the added home value from solar is excluded from property tax reassessment in Colorado.
  • Sales tax: ✅ Yes — solar equipment is exempt from state sales tax in Colorado, saving typically 5-8% of gross cost.

5. Utility rebates & notes

Xcel Energy Solar*Rewards rebate available. HOA restrictions on solar prohibited.

Utility rebates change frequently. Verify current terms with your specific utility (not just "the state") before signing an installer contract.

Bottom line for Colorado

A typical 6.0 kW rooftop system in Colorado costs about $18,000 gross → $12,600 after the federal ITC. With Colorado’s electricity rate of 16.54¢/kWh, this system saves about $1,554/year — paying back in 8.1 years on the federal credit alone. Add the state-level items above and the net cost drops further.

FAQ

Can I combine federal ITC and Colorado’s state incentives?

Yes — the federal ITC and Colorado’s state credit stack independently. However, some utility rebates reduce the "cost basis" the federal ITC applies to. Consult a CPA.

When do I get the federal ITC money?

The ITC reduces your federal income-tax liability for the year the system is placed in service (i.e., commissioned and producing power). If your tax owed is less than the credit, unused portions roll forward. You do not receive a check.

Do rebates and credits get taxed?

Rebates from utilities are generally not taxable (they reduce your cost basis). Federal tax credits are not income. Some state credits may be treated differently — check your state Department of Revenue.
