Idaho rebate questions

Can I still get a federal tax credit in Idaho?

No. 25C and 25D were both repealed by the One Big Beautiful Bill Act for property placed in service after December 31, 2025. Anything installed in Idaho in 2026 earns no federal residential energy credit. Work finished on or before that date can still be claimed.

Are the Idaho state rebates open yet?
