4 things to know about the federal solar power tax credit

More and more accountants are recommending their homeowner clients consider solar panels. Here’s why.

When solar panels are installed on rooftops, the sun beats down on them, producing electricity that can potentially help homeowners save money on monthly electric bills and reduce their carbon footprint. This solar-generated power is used in the home first, and any excess can be fed into a battery instead of back to the grid, which means homeowners will have access to this power during outages. The battery backup can be a potential significant cost savings when you consider monetary losses that could result from spoiled food, medication or the inability to work from home.

In 2005, the federal solar investment tax credit (ITC) was established, and it has been extended multiple times since. When it first passed, the value of the credit was at 30 percent, but it fell to 26 percent in 2020. The latest extension of the solar tax credit came last December, and it gives homeowners and businesses up to a 26 percent credit on the net cost of a solar system. The 26 percent credit is in effect for two more years before it drops to 22 percent in 2023 and sunsets altogether for homeowners in 2024. The credit for businesses follows a similar path, with the exception being that its credit falls to 10 percent in 2024 and will stay at that number in future years.

Accountants and tax advisors have long recognized the value of this credit for their eligible clients. Not only homeowners but businesses who own buildings, even stadiums and arenas, can leverage it to reduce the net cost of their solar systems.

Below are four things you need to know when advising your clients:

Qualifying homeowners can reduce the cost of their system.

Homeowners are generally eligible for the credit provided they have tax liability in the year the solar system is placed into service. The federal solar tax credit can reduce the net cost of the solar system by up to 26 percent, the current amount of the credit. Put another way, for every $10,000 of solar that you purchase, you could receive a credit for up to $2,600 on your federal taxes.

The solar tax credit has a rollover factor.

If a homeowner cannot utilize the full 26 percent tax credit in the year they have placed the system into service, the leftover amount may be able to be carried over into future tax years. For example, if the maximum credit you could receive is $6,000, and you have only $4,000 of tax liability in the year you place the system into service, you may be able to carry over the remaining $2,000 to the following year.

Solar work must be installed before the sunset date.

The 26 percent credit will drop to 22 percent in 2023, and sunsets thereafter for homeowners. Remember, solar projects take weeks or months to be approved for installation, so those waiting to sign up for solar in December 2023 will most likely miss out on the opportunity to claim any credit.

Be aware of additional tax credits.

Some states offer additional tax credits, and certain municipalities and utilities also offer cash rebates or other incentives, for homeowners who install solar panels. Take the time to conduct research in each locality and state. Additionally, it is important to note if your clients are eligible for these tax credits that they can lower the net cost of the solar system further. Solar power can potentially save them money now and later.
