What you need to bring for the Energy Efficient Credit.
New Changes to requirements for claiming the Energy Efficient Home Improvement Tax Credit in 2025
Starting this year, the IRS is implementing a requirement for manufacturers to establish a PIN number for each eligible product, so it can be associated with the tax credit claim. Manufacturers are currently in the process of becoming “qualified manufacturers” or QMs. Because manufacturer registration is in process, it will be sufficient, for installations in 2025, to simply include the manufacturer’s four-digit QM code on your 2025 tax return. This applies to heat pumps (outdoor unit only), water heaters, CAC, boilers, furnaces, biomass stoves, windows, doors and skylights. (The QM code requirements applies for electric panel upgrades but will remain sufficient in future years.)
