Incentives that apply in Idaho

Federal (2026 update)

The 30% federal Residential Clean Energy Credit ended for systems placed in service after December 31, 2025. If you buy with cash or a loan in 2026, there's no federal credit. A lease or PPA can still capture a 30% commercial credit — worth roughly $6,720 on a typical Idaho system — which the provider passes on through lower payments. More in our federal tax credit guide.
