The Investment Tax Credit (ITC), popularly known as the federal solar tax credit, is THE most important solar credit. It provides tax credit of 30% for the purchase price of a solar system against your federal income taxes, and covers both residential and commercial solar installations, bringing down the cost of the system enormously. EVERY person in the US who installs a solar system is allowed to claim this credit on their federal income taxes
Put simply: You get 30% of the cost of a solar system back as a tax credit.
There is no limit to how much of a tax credit the ITC provides, and with US prices for residential solar systems averaging roughly $22,000, homeowners who purchase their system with cash or through a loan can save $6,600 on their system due to the ITC. A tax credit of 30% towards the cost of a solar panel installation is enormous – and you are able to take all of this tax credit in the year you install your solar system.
While most people installing systems have enough federal tax liability to take the entire credit in the first year, you are allowed to roll it over into a second year. Rolling it into a third year is a subject of debate among accountants – it’s best to use your tax credit within two years of installing your system.
Everyone who installs a solar system in the US in an eligible year is eligible for the Investment Tax Credit, and as long as your accountant fills out the proper paperwork correctly there is nothing that should stop you from receiving the credit.
This part is IMPORTANT. The ITC is going to be ramping down over time – meaning that the longer you wait on going solar, the lower of a solar panel tax credit you will receive.
See the below diagram for the ramping down of the ITC over time – what this graph indicates is that if you have begun construction on your solar panel installation before December 31st 2019, you will be eligible for the full 30% tax credit. Installations begun between January 1, 2020 and December 31, 2020 will be eligible for a 26% tax credit, installations begun between January 1, 2021 and December 31, 2021 will be eligible for a 22% tax credit, and installations begun between January 1, 2022 and December 31, 2022 will be eligible for a 10% tax credit. After that, there will be NO tax credit for homeowners, only commercial solar installations.
That just happens to be the name that it was given by congress – many people are confused by why it wasn’t called the Federal Solar Tax Credit or something – we are too. Solar IS an investment that provides handsome returns – but we agree, they could have come up with a better name.
