How to Claim State Tax Credit
After installing a qualifying system, you claim the credit on your state income tax return for the install year. If your state tax liability is too low to absorb the full credit, most states allow carry-forward for 5 to 10 years until used.

State income tax credits stack cleanly with the federal credit because they apply to a different tax authority. They typically do not reduce the federal credit basis. Property tax and sales tax exemptions also stack independently.
