Safe Harbor Options for Taxpayers as the Solar ITC Begins to Sunset

By Mark Vitello, BerryDunn

Read this if you are a solar investor, developer, or installer.

The solar carve out of the Investment Tax Credit (ITC) has been a great incentive for taxpayers to invest in solar assets over the last several years. It established an increased 30% tax credit for solar assets placed in service, up from the normal 10%.

Starting January 1, 2020, the solar carve out will begin to phase out and will return to 10% by January 1, 2024. 

With the first phase-out of the ITC set to drop the credit from 30% to 26% after December 31, 2019, many taxpayers are evaluating ways to make sure their project still qualifies for the 30% credit. The IRS has issued two safe harbor provisions (IRS Notice 2018-59) to allow for projects placed in service after December 31, 2019 and before January 1, 2024 to still qualify for the 30% credit, but timing is key and certain actions must be taken before midnight on December 31, 2019.

Safe harbor methods

The two safe harbor methods are the Physical Work Test and the Five Percent of Cost Test. If a project satisfies either of these tests it can still qualify for the 30% tax credit as long as it is completed and in service before January 1, 2024.

The Physical Work Test requires that the taxpayer performs, or has performed on their behalf, “work of a significant nature” on the project prior to December 31, 2019. This is a little open to interpretation, but generally involves physical construction of the asset, such as the installation of mounting equipment, rails, racking, inverters, or even the panels themselves. Purchasing of equipment generally held in inventory by either the taxpayer or the vendor does not qualify. However, if the equipment is customized or specially designed for the specific project, it might. Preliminary activities do not qualify, which include planning, designing, surveying, and permitting.

In general, the purpose of this test is to prove that construction has already begun, and is in place to help projects that have been started but won’t be in service before year end still maintain the 30% tax credit. Projects that are substantially complete and waiting for an interconnection or a permission to operate in order to be considered as in service will most easily qualify for this safe harbor test.

The Five Percent of Cost Test is a little more straightforward, and is likely to be more commonly used to qualify projects for the safe harbor provision as the end of the year deadline approaches. This test requires at least five percent of the total project cost be paid or incurred before December 31, 2019. It is important to note that the denominator in this test is the final total cost of the project when it goes in service. The taxpayer may wish to pay more than the five percent to account for project overruns or unanticipated changes to the project in order to make sure they maintain the qualification for safe harbor.

Another consideration is if the taxpayer files on the cash or accrual method as to whether the project cost needs to be paid or incurred in order to satisfy the chosen filing method.

In either case, the taxpayer should also evaluate the cost of prepaying for equipment that may decrease in cost in the future, compared to the benefit they will receive in maintaining the additional four percent of the tax credit that can safe harbor from the phase out.

Additionally, an analysis of total project costs and eligible vs. ineligible ITC costs early on in project development can help identify how best to spend the cash before the end of the year, and ensure that the taxpayer receives the return they require once the project goes into service.
