A federal tax credit for the purchase and installation costs of a residential solar system is fading away. After being 30% of the cost for several years through 2019, the credit amount drops to 26% in 2020. In 2021, the final year of the credit, it drops again to 22%.

The credit is non-refundable, meaning it can only reduce an individual’s tax liability to zero. However, the portion of credit not allowed because of this limitation may carry to the next tax year and add to the credit allowable for that year. The tax code infers that you may add any credit carryover to the credit allowed in the subsequent year.

However, some things are unclear. For example: Will any carryover be allowed to 2022 once the credit expires at the end of 2021? In addition to the credit reducing the regular tax, it also reduces the alternative minimum tax should a taxpayer be subject to it. Read on for Fiducial’s primer on the fading solar tax credit.

Solar credit qualifying property

Only the following solar power systems are eligible for the credit:

  • Qualified solar electric property – property that uses solar energy to generate electricity for use in a home that is the taxpayer’s main or second residence.
  • Qualifying solar water heating property – qualifies if used in a dwelling located in the U.S. and used by the taxpayer as a main or second residence. At least half of the energy used to heat the residence’s water must be derived from the sun. Heating water for swimming pools or hot tubs does not qualify for the credit. The solar equipment must be certified for performance by the Solar Rating Certification Corporation or a comparable entity endorsed by the state government where the property is installed.

When is the solar credit available?

Purchasers may claim credit on the tax return of the year during which they complete installation. So, if a taxpayer has purchased and paid for a system and completed installation in 2020, the credit will be 26% of the cost. But if you did not complete the project until 2021, the credit drops to 22%.

This becomes an even a bigger issue for systems being installed during 2021 but not completed before 2022, when the credit rate will be zero. Are you planning to purchase a solar system in 2021? Make sure to complete the purchase early enough in the year to ensure complete installation before 2022.

Who gets the solar credit?

It may come as a surprise, but the taxpayer need not own the residence where the solar property is installed to qualify for the credit, as the taxpayer need only be a “resident” of the home. The tax code does not specify that an individual has to own the home, only that it is the taxpayer’s residence. For example: A son lives with his mother, who owns the home. The son pays to have the solar system installed; the son is the one who qualifies for the credit.

Multiple installations

The credit is available for multiple installations. For instance, after the initial installation, if a taxpayer adds additional panels to increase capacity, these would be treated as original installations. They would qualify for credit at the credit rate applicable for the year of the additional installation completion provided that the installation finishes before 2022.

What happens if a taxpayer had to replace damaged panels or perform other maintenance on the system? These items would not be an original system and their costs would not qualify for the credit.


A battery qualifies for the credit if it’s charged only by solar energy and not off the grid. This has become popular in areas where there are frequent power outages. However, this may be more of a convenience than a necessity, so carefully consider the cost. A software-management tool—whether part of the original installation or added later (before 2022)—also qualifies for the credit in cases in which the software is necessary to monitor the charging and discharging of solar energy from a battery attached to solar panels.

Installation costs

Amounts paid for labor costs allocable to onsite preparation, assembly, or original installation of property eligible for the credit, and for piping or wiring connecting the property to the residence, are expenditures that qualify for the credit. This includes expenditures relating to a solar system installed on a roof or ground-mounted installations.

Basis adjustment

The term basis generally refers to the cost of a home plus improvements and is the amount subtracted from the sales price to determine the gain or loss when the home is sold. The cost of a solar system adds to a home’s basis, and the credit reduces the basis. This will generally create a different basis for federal and state purposes where a state does not provide a solar credit or it differs from the federal solar credit amount.

Association or cooperative costs

A taxpayer who is a member of a condominium association for a condominium they own, or a tenant-stockholder in a cooperative housing corporation, is treated as having paid their proportionate share of any qualifying solar system costs incurred by the condo or cooperative association or corporation.

Mixed-use property

If you use a portion of a residence for deductible business or rent it to others, you must prorate the expenses. You may only use the personal portion of the qualified solar costs to compute the credit. An exception occurs when one uses less than 80% of the property for non-business purposes. In this case the full amount of the expenditures is eligible for the credit.

Newly constructed homes

If you plan on purchasing a newly constructed home that includes a solar system, a solar credit may still come to you. However, to claim it, you must separate the costs of the solar system from the home construction costs. Also, you must make certification documents available.

How does a utility subsidy affect the solar credit?

Some public utilities provide a nontaxable subsidy (rebate) to their customers for the purchase or installation of energy-conservation property. In that case, the cost of the solar system that’s eligible for the credit must be reduced by the amount of the nontaxable subsidy that was received.

Solar installations are not for everyone

There are TV ads, telemarketing phone calls and sales people at your front door all promoting the benefits of solar power. One of the key considerations and benefits they frequently mention is the federal tax credit.

What isn’t included in the ads—and something most potential buyers are unaware of—is that the solar credit is a nonrefundable tax credit. This means that you may only use the credit to offset your tax liability. This can come as a very unpleasant surprise and is often a financial hardship when the purchaser of a home solar system finds out that the credit is nonrefundable and that they won’t benefit from the full credit.


For example, a married couple with three children, all under age 17, and an annual income of $80,000 installed a solar system costing $20,000 in 2020. They expected a $5,200 ($20,000 x 26%) credit on their tax return.

Their standard deduction in 2020 is $24,800, leaving them with a taxable income of $55,200. The tax on the $55,200 is $6,229. They will also receive a $2,000 child tax credit for each child. This reduces their tax liability by $6,000 and results in a tax liability of $229. Since the solar credit is nonrefundable, the only portion of the credit they can use is $229. Unfortunately, they cannot claim the $5,200 they had expected.

On top of that, the family is probably financing the solar system, which significantly adds to the system’s cost. If they financed the entire $20,000 cost with a 5% home equity loan for 20 years, then the interest on that loan over its term would amount to $11,678. This brings the total cost of the solar system to $31,678 or a monthly cost of $132.
In lieu of purchasing a solar system, some homeowners opt to lease a system. This arrangement is not eligible for the solar credit.

Should You Take Advantage of the Solar Credit?

As you can see, there is a lot to consider before making the final decision to install a solar system. Is it worth it, and is it the right financial move for you? Before signing any contract, ask your Fiducial rep if a solar system is appropriate for you. Call Fiducial at 1-866-FIDUCIAL or make an appointment at one of our office locations.
