Home Energy Savings Act of 2021
This bill extends the nonbusiness energy property tax credit through 2031 and increases the credit percentage from 10% to 30% for qualified energy efficiency improvements. The bill also imposes a $1,200 annual limitation on the credit and limits for windows and doors.
The bill allows a credit for 30% of the cost of home energy audits. A home energy audit is an inspection and written report for a taxpayer's principal residence that identifies the most significant and cost-effective energy efficiency improvements and is conducted and prepared by a certified home energy auditor.
The bill also requires that energy property placed in service after 2023 be produced by a qualified manufacturer and that the taxpayer includes the qualified product identification number for such property on the return of tax.
To amend the Internal Revenue Code of 1986 to extend, increase, and 
             modify the nonbusiness energy property credit.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Home Energy Savings Act of 2021''.
