Update: As of July 4th, 2025, the reconciliation bill has become law. With it come the following changes to the federal solar tax credit. Homeowners now have until December 31st, 2025 to receive the 30% federal tax credit for solar and home battery backup. Commercial property owners can secure the 30% tax credit plus any applicable adders until July 4, 2026, or for systems placed in service by December 31, 2027. Additional Foreign Entities of Concern (FEOC) rules impact projects beginning January 1, 2026. Contact Namaste Solar today to preserve your 30% tax credit by getting your project safe harbored in the calendar year of 2025 and to be placed in service prior to December 31, 2027.

Blog Updated: July 2025
Since it was enacted in 2006, the solar Investment Tax Credit (ITC) has helped support the growth of solar energy across the country. Both homeowners and commercial property owners are able to recoup 26% of the solar system price, improving the economics of a solar investment. The tax credit is claimed on federal income taxes and can be monetized the first year after system operation. It is scheduled to step down after 2022 and will sunset completely for residential systems after 2023, while remaining at a permanent 10% for commercial systems.
For homeowners, the guidelines are clear that they need to have their system installed and placed in service by the end of the 2022 to be eligible for the 26% ITC. Commercial entities, however, can secure this year’s higher tax credit by safe harboring their project. This blog post will cover the concept of safe harbor and how Namaste Solar can help commercial projects preserve the 26% tax credit before it decreases to 22% in 2023.
What is Safe Harbor?
The IRS established a provision to the ITC tax law called safe harbor which allows customers to preserve the tax credit of a given year by beginning construction on a solar project. The definition of what beginning construction means is at the heart of safe harbor and is what a prospective solar buyer should be aware of in considering a safe harbor strategy. There are two approaches that qualify as beginning construction: The first safe harbor mechanism is to incur 5% of total project cost, and the second is to begin physical work of a significant nature on a project.

“Both are considered acceptable proof of beginning construction and demonstrate that work has been initiated.”
Incur 5% of Total Project Cost
The Five Percent Safe Harbor Test requires at least 5% of the price to be incurred on qualifying equipment such as solar modules, racking, and inverters. The requirement for this varies based on the accounting method of the project owner, and in general, title transfer of equipment must occur within the given year to qualify. While 5% is the minimum required, Namaste Solar recommends purchasing the solar panels for a project, which accounts for a larger percentage of the cost. This allows you to lock in pricing for your panels and is often the cleanest way to achieve safe harbor.
Begin Physical Work of a Significant Nature
Physical work of a significant nature refers to evidence that work has started on something qualitatively significant. Both on-site and off-site work is considered acceptable, and can be performed by the project owner, a contractor, or a subcontractor. Either way, a binding contract must be in place that demonstrates the owner’s assumption of risk. This option also refers to the procurement of components specific to the project which are not normally held in the manufacturer’s inventory, such as custom racking, carports, and transformers. Assuming the work performed is of a significant nature, there is no fixed minimum amount of work, monetary amount, or percentage threshold required to satisfy the physical work test.
