IRA Updates to the Solar Investment Tax Credit (ITC)

Among the Inflation Reduction Act’s expansions to existing tax credit opportunities are those that promote the adoption of solar energy systems. The IRA extends the provisions of the Solar Investment Tax Credit (ITC), so residential homeowners who install designated solar energy systems between January 1, 2022 through the end of 2032 will receive a tax credit of 30% of the cost from their federal income taxes.

If owners owe less than that amount in federal taxes for the year they install their solar system, they can carry over any unused credit for as long as the ITC is in effect, January 1, 2032.

After 2032, the residential ITC will start to phase out to 26% in 2033, 22% in 2034, and will end in 2035. It’s important to note that the IRA’s Investment Tax Credit expansions are not retroactive for residential solar projects that were placed in service prior to 2022.

Advanced Manufacturing Production Credit, Section 45X

The Inflation Reduction Act created a new Production Tax Credit (PTC), the Advanced Manufacturing Production Credit (Section 45X), that can be applied to the domestic production and sale of qualified solar, wind, and battery components.

Qualifying solar components eligible for these credits include thin film photovoltaic cell or crystalline photovoltaic cells, photovoltaic wafers, solar grade polysilicon, polymeric backsheet, and solar modules. The amount of each credit is defined as a set amount per watt, e.g., 4 cents multiplied by the wattage capacity for photovoltaic cells, or as a set amount per production quantity, e.g., $12 per square meter for photovoltaic wafers. These provisions allow the government to increase support as production volumes increase and are expected to significantly expand solar manufacturing in the U.S., including wafer and cell manufacturing where China is now the global leader.

The Advanced Manufacturing PTC cannot be claimed for components produced at a facility for which a credit was claimed for investments in manufacturing facilities for clean energy technologies under the Section 48C Advanced Manufacturers Tax Credit. They must also be produced after December 3, 2022, and will begin to phase out starting in 2030.

Section 45X Qualifying Solar Components

  • Solar modules
  • Photovoltaic cells
  • Photovoltaic wafers
  • Solar grade polysilicon
  • Torque tube or structural fasteners
  • Polymeric backsheets
  • Solar tracker 

Section 45X Applicable Tax Credits

  • Photovoltaic cells = 4 cents X current watt of such cell
  • Photovoltaic wafer = $12 per square meter
  • Solar grade polysilison = $3 per kilogram
  • Polymeric backsheet = 40 cents per square meter
  • Solar module = 7 cents X current watt of such module
  • Torque tube = 87 cents per kilogram
  • Structural fastener = $2.28 per kilogram

Direct Pay Options for Not-for-Profit Organizations

Organizations that are not subject to federal income taxes, such as those with a 501(c) designation, are not able to benefit directly from the Solar Investment Tax Credit; however, the Inflation Reduction Act has created tax incentives through a “direct pay” option.

For tax year beginning after December 31, 2022, and before January 1, 2033, tax-exempt entities, states, political subdivisions, the TVA, Native American tribal governments, Alaska Native Corporation and rural electricity co-ops can treat designated tax credits as refundable payments of tax. These nonprofit entities are able to receive direct payment in lieu of credits pertaining to renewable energy production. For example, if a tax-exempt town, city, or village with municipal utilities finances a solar photovoltaic array (linked collection of solar modules) to generate electricity, they would qualify for a direct payment. However, if the solar array project is financed with 100% tax-exempt debt, the direct pay amount to the municipality will be reduced by the lesser of 15% OR the portion of the project that has been financed with tax-exempt debt.
