The newly enacted Inflation Reduction Act contains tax credits and depreciation benefits for owners of commercial property and residential rental property.

If you implement various types of renewable energy improvements, you can qualify for hefty tax credits or deductions.

One caution: the rules are complex.

That said, bear with the rules because the benefits are worthwhile.

Business Energy Investment Tax Credit

The business energy investment tax credit (ITC) is used primarily for solar panel installations on commercial buildings and residential rentals.

The ITC has been available and continues for small wind power installations, fuel cells, microturbine, waste energy recovery, geothermal, and combined heat and power. The new law extends the ITC to stand-alone battery storage, biogas (such as landfill gas), and microgrid controllers.

The new law retroactively increases the base ITC from 26% to 30% of depreciable basis for projects that are placed in service after 2021, provided that construction commences before 2025.

To realize the full tax credit, you must continue to own the property for five years after the energy installation, or the government will recapture some or all of the credit.

Increasing The Itc To 40%, 50%, Or More

Starting in 2023 (in other words, coming soon), businesses can also utilize stackable “bonus” ITC adders that can increase the total ITC to a whopping 40%, 50%, or more.

  • Domestic content bonus. You can earn a 10% ITC bonus (bringing the ITC to 40%) if a project satisfies the domestic content requirement. (100 percent of the steel and iron used must be U.S.-sourced. Manufactured components must be at least 40% U.S.-sourced.) But the Treasury secretary can provide exceptions to these rules if they result in cost increases of over 25% or if comparable products are not readily available in the U.S.

  • Low-income community bonus. You earn a 10% ITC bonus if a solar or wind facility is located in, or services, a low-income community.

  • Qualified low-income residential building project bonus. You earn a 20% ITC bonus for solar or wind installations for residential buildings if (a) the building owner participates in various federal low-income housing programs, or (b) 50% of the affected building households have income of less than 200 percent of the federal poverty line or less than 80 percent of the area’s median gross income.

  • Energy community bonus. You can earn a 10% ITC bonus if the project in located in or on(a) a brownfield site, (b) an area with significant employment related to fossil fuels, or (c) a coal-related census tract.

Special Depreciation Benefit

The year you place your solar or other energy installation in service, you may depreciate it. Ordinarily, you reduce the basis of depreciable property by the full amount of any credit. But the ITC reduces the energy property’s basis by only half the credit amount, increasing your depreciation deductions.

Five-year Depreciation

IRC Section 48 energy property gets a five-year depreciation period under MACRS (this is generous because solar panels usually last 25 to 30 years).

Bonus Depreciation

Here’s more good news. The 80% first-year bonus depreciation is available for energy improvements for residential rental or commercial property placed in service during 2023; the depreciation is 60% for 2024.

Can’t Use The Itc? Sell It

The ITC is non-refundable, but it is transferable. That is, you may transfer all or part of your ITC to another taxpayer for cash.

The buyer of your ITC need not be a business or be involved in the renewable energy industry (but the person or entity may not be related to you).

The buyer must pay you for the ITC in cash. You are not taxed on the payment. It’s tax-exempt income for you.

The credit must be transferred by the due date of the tax return for the taxable year in which the credit is determined. A credit may be transferred only once.


The ITC in its current form expires in 2024. It will be replaced with a new, technology-neutral clean electricity ITC.

Under the new credit, any project producing electricity will qualify for a 30% clean energy ITC if its greenhouse gas emissions rate is not greater than zero. The clean energy ITC will phase out by the later of:

  • 2032, or

  • when the electric power sector emits 75% less carbon than 2022 levels.

Energy-efficient Commercial Buildings Deduction

Since 2006, owners of commercial buildings have been able to claim an immediate first-year deduction for part of the cost of making existing or new buildings more energy-efficient. The Inflation Reduction Act significantly increases the amount of this deduction starting in 2023.

Note that this is simply an accelerated tax deduction, not a tax credit.

Other Choices

Building owners can deduct many of these same expenses in one year using Section 179 expensing without having to comply with the complex rules for the Section 179D deduction. But there is an annual limit on the Section 179 deduction ($1,080,000 for 2022).

Bonus depreciation is also available to deduct many of these expenses in one year, but it will be reduced from 100% in 2022 to 80% in 2023 (and to 60% in 2024).

Commercial And Multi-family

The Section 179D deduction is only for commercial buildings and multi-family residential buildings of four stories or more. It is not available for rentals of single-family homes, multi‐family buildings of three stories or less, mobile homes, or manufactured homes.

Building owners qualify for the deduction when, as part of a plan to reduce total energy costs, they upgrade a building’s

  • interior lighting system;

  • heating, cooling, ventilation, or hot water system; or

  • building envelope—for example, roofs, walls, floors.

Old 50 Percent Rule

Under the old deduction, building owners had to improve a building’s energy efficiency by 50% as compared with a hypothetical reference building that meets an efficiency engineering standard established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE Standard 90.1).

New, Easier 25 Percent Rule

Under the revised deduction, building owners only have to improve energy efficiency by a minimum of 25%.

And the maximum deduction amount increases for every percentage point of energy efficiency above the 25% benchmark.

Old Deduction

The old deduction was capped at $1.88 per building square foot in 2022.

New Deduction

Starting in 2023, the deduction cap is increased to $5 per building square foot (subject to annual inflation adjustments). But to claim the $5-per-square-foot deduction, building owners must comply with prevailing wage and apprenticeship requirements. If those requirements are not met, a building owner may claim only a $1-per-square-foot maximum deduction.

Electric Vehicle Charger Credit

The Inflation Reduction Act extends through 2032 the tax credit for installing an electric vehicle charging station in a commercial or rental building garage or parking lot.

Prevailing Wage Rules Apply Here Too

Starting in 2023, the credit remains 30% of the cost of installing such chargers, but only if the project complies with prevailing wage and apprenticeship requirements (these are the same requirements discussed above).

If the project does not comply with these requirements, the law reduces the credit from 30% to 6%. The maximum annual credit is now capped at $100,000, and the cap applies per charger unit.

Under prior law, there was a $30,000 annual cap for an entire location regardless of the number of chargers.

More Chargers Qualify

The credit is also extended to include bi-directional chargers that can be used to power a home and feed energy back into the electricity grid.

The credit now also applies to chargers for two- and three-wheeled vehicles.

New Geographic Requirement

The electric charger credit is subject to a new geographic requirement that will greatly limit its availability. Starting in 2023, it will be available only for property located in low-income or rural areas.

Low-income census tract. The charging station must be located in a low-income census tract that has a poverty rate of at least 20% or a median family income of less than 80% of the statewide median.

Rural area. Alternatively, the charging station must be in a non-urban area. This is an area not designated as an urban area by the U.S. Commerce Department in the most recent census. Less than 20% of the U.S. population lives in such rural areas.

General Business Credit

The electric vehicle charger credit is part of the general business credit.

The basis of the property for which a credit is claimed must be reduced by the amount of the credit.


The Inflation Reduction Act extends and expands business ITCs for installing solar and other renewable energy facilities in commercial and rental buildings. The new law retroactively increases the ITC from 26% to 30% for projects begun after 2021 and before 2025.

Starting in 2023, you can earn bonus credits giving you 40%, 50%, or more in ITC. You earn the bonus credits for projects that:

  • comply with domestic content requirements,

  • are located in low-income communities,

  • participate in federal housing programs, or

  • are located in communities involved with fossil fuels.

The ITC in its current form expires in 2025, to be replaced with a new technology-neutral, 30% clean electricity ITC.

The Energy Efficient Commercial Buildings Deduction can now be obtained for projects that increase a building’s energy efficiency by 25% instead of 50%. Starting in 2023, the cap on the deduction is increased to $5per building square foot if prevailing wage and apprenticeship requirements are met. If these requirements are not met, a building owner may claim only a $1-per-square-foot maximum deduction.

The credit for installing electric vehicle charger units in commercial or rental buildings is extended to 2032. Starting in 2023, the following rules govern:

  • The 30% credit is available only for projects that comply with prevailing wage and apprenticeship rules; otherwise, it is reduced to 6%.

  • The credit is available only for property located in low-income or rural areas.

  • The annual cap on the credit is increased to $100,000 per charging unit.
