Replacement Windows in Oklahoma

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

Oklahoma's roughly $129 million in IRA Home Energy Rebate funding is administered by the Oklahoma Department of Commerce State Energy Office, but the consumer-facing HOMES/HEAR programs had not launched as of mid-2026 — utility rebates remain the main incentive in the meantime.

• OG&E residential efficiency rebates and weatherization. OG&E offers rebates for home upgrades that include windows and doors along with attic insulation and smart thermostats, plus a free weatherization program for income-qualified customers; amounts and eligibility change, so verify current offers with OG&E.

• Oklahoma Natural Gas rebates. ONG offers residential rebates focused on natural gas equipment and weatherization measures; windows generally do not qualify under ONG's program, so it matters mainly as part of a broader efficiency project. (Oklahoma Natural Gas rebates and incentives page)

Energy code

Oklahoma sets a statewide minimum code through the Uniform Building Code Commission based on amended IRC/IECC editions (with 2024 codes slated to take effect in late 2026), and home-rule jurisdictions may adopt stricter local amendments.
