Does a new insulated garage door count as a new exterior door?

[IreneS]

Yes - The IRS does not make a distinction according to where the exterior door is located (house or garage).

However, according to the instructions for Form 5695 - Residential Energy Credits:

Beginning in 2016, exterior doors, exterior windows, and skylights will only be eligible for the nonbusiness energy property credit if they meet or exceed the specific requirements of the version 6.0 Energy Star program .
