Residential Energy Conservation Subsidy Exclusion (Corporate)
According to Section 136 of the U.S. Code, energy conservation subsidies provided (directly or indirectly) to customers by public utilities* are non-taxable. This exclusion does not apply to electricity-generating systems registered as "qualifying facilities" under the Public Utility Regulatory Policies Act of 1978 (PURPA). If a taxpayer claims federal tax credits or deductions for the energy conservation property, the investment basis for the purpose of claiming the deduction or tax credit must be reduced by the value of the energy conservation subsidy (i.e., a taxpayer may not claim a tax credit for an expense that the taxpayer ultimately did not pay)
