Inflation Reduction Act Expands 179D (Energy Efficient Commercial Buildings Deduction)
Oct 17, 2022
The Inflation Reduction Act of 2022 (2022 IRA) was passed to incentivize investment in clean energy and promote the reduction of carbon emissions. A large share of the incentives come in the form of tax credits, which in some cases are extensions or expansions of current credits, such as those for electric vehicles or residential energy upgrades.
Of the tax provisions introduced by the 2022 IRA, one of the most significant to businesses has been the expansion of the Energy Efficient Commercial Buildings Deduction (§179D), which increases the maximum deduction and updates the eligibility requirements for a property’s reduction of energy costs, in addition to other changes.
Under the expanded provision, a deduction is allowed for all or part of the cost of certain energy-savings improvements made to domestic, commercial buildings placed in service as part of the building’s:
- interior lighting systems
- heating, cooling, ventilation (HVAC), and hot water systems
- building envelope
The tax deduction benefits both commercial building owners and lessees along with designers of government-owned buildings. Additionally, the provision states that installation of energy-efficient property may occur as a result of new construction, or through the improvement of an existing commercial or government building.
Efficiency standard: To qualify for the deduction, newly updated eligibility requirements call for energy-efficient property to reduce associated energy costs by 25% or more (decreased from 50% or more) in comparison to a reference building that meets the latest efficiency standards.
Applicable amount: The applicable dollar value of the deduction is $0.50 per square foot, an increase of $0.02 for each percentage point above 25% that a building’s total annual energy cost savings are increased. However the amount cannot be greater than $1/ square foot, and the maximum amount of the deduction in any tax year cannot exceed $1/ square foot minus the total deductions taken over the previous three years (or during a four-year period in cases where the deduction is allowable for someone other than the taxpayer). The applicable dollar value will be adjusted for inflation for tax years beginning after 2022.
An increased dollar value is available for projects that satisfy prevailing wage and apprenticeship requirements for the duration of the construction.
Alternative deduction for energy-efficient retrofit property. Under the 2022 Inflation Act, taxpayers may elect to take an alternative deduction for a qualified retrofit of any eligible property. However, instead of a reduction in total annual energy power costs, the deduction is based on the reduction of energy usage intensity.
