Read this if you are a solar developer, installer or investor.
Much of the focus in the renewable energy space has been on the commercial Investment Tax Credit (ITC), due to the size of the projects and the money involved. Certainly the nuances of passive vs. active income and basis limitations drive a lot of the conversation about investing in a large scale project. But what about the residential credit? In some ways the residential credit is simpler, but many questions remain. Here we explain some of the differences and things unique to the residential credit to hopefully clear up some of your questions.
Where can the project be located?
Per the regulations for the residential ITC, the solar-energy producing equipment needs to be located on a “home” owned by the taxpayer. This is important because it does not say “primary residence”, but “home”. So the project could be on your primary residence, or it could be on your vacation home on Cape Cod. The important thing here is that the property is used as a “home”, or residence. If you are putting the solar project on a rental property then that would fall into the commercial ITC category, not the residential.
When can I claim the credit?
The credit is claimed on the tax return for the year the project is placed in service. Being placed in service is defined as being operational for its intended purpose—so in other words, not only does it need to be installed, it has to be turned on and operating. Some projects get stuck in the inspection queue at year end and don’t get approved until after the first of the next year. If that happens to you, unfortunately your credit will need to be claimed on the next tax return. Unlike the commercial ITC, there is no provision for a safe harbor for the credit. If you don’t reach full installation and operation by December 31, 2022 then you are only eligible for the 22% credit instead of the 26% credit you would have gotten if the project was completed in 2022.
What costs qualify?
Only the costs for equipment that is integral to the production of energy qualify for the credit. This includes panels, racking, and inverters, but can also include some other costs, depending on the circumstances. It does not include improvements and enhancements to your roof that are not directly related to the production of energy. This tends to be a bigger issue on commercial projects where the added weight of the equipment and the slope of the roof require additional work to be done. However, a skylight added to your roof is not part of the solar energy equipment, and the cost of that addition should be excluded from your total cost, even though it may be helping to make your home more energy efficient. The cost of replacing a roof does not qualify, but in certain cases upgrades to the roof can be included.
What about depreciation?
Depreciation is the annual expensing of a commercial asset. Since the project is on your home, there is no depreciation expense to claim. Instead, the cost of the energy equipment installed on your house becomes part of your cost basis, or original purchase value, of your house. In the future if the house is sold, this cost will help reduce the amount of taxable gain on the sale.
What about storage?
Battery storage has been a part of renewable energy projects for years, but as the technology gets better and more cost effective it is becoming a bigger part of project offerings. Currently, a battery storage system is only eligible for the residential ITC if it is installed at the same time as the energy-producing equipment. This is the same for both the residential and commercial credit. In addition to being installed as part of the original project cost, the battery must also be charged by the renewable energy-producing equipment. If it draws a charge from the grid or from another non-renewable energy source, it will not qualify for the ITC.
We have been watching the activity in Washington, D.C. carefully since President Biden took office. One of the items in the proposed tax bill is an expansion of the Investment Tax Credit to allow for stand-alone energy storage equipment to qualify. While this is still in discussion and no legislation has passed yet, this change to the rules could potentially allow for battery storage to be added to existing projects, and the taxpayer taking the ITC on the cost of adding the battery storage equipment.
Every project, home, and taxpayer’s situation is different, so it is important to discuss your individual project and tax situation with your tax advisor. As we have described here, the residential and commercial ITCs are similar, but not the same. However, both have the potential of being beneficial to the taxpayer, and perhaps at a greater level to environment.
