Federal Solar Investment Tax Credit (ITC)
Your solar system must be installed before January 1st, 2023 in order to qualify for the entire 26% rebate. In 2023, this rebate will be reduced to 22%, and this incentive is going away in 2024. Below is a timeline of anticipated federal rebate changes.
2022: Owners of new residential and commercial solar systems can deduct 26% of the cost of the system from their federal tax obligations.
2023: Owners of new residential and commercial solar systems can deduct 22% of the cost of the system from their federal tax obligations.
2024: Owners of new commercial solar only (not residential) can deduct 10% of the cost of the system from their federal tax obligations. The ITC vanishes for homeowners in 2022.
Understanding Cost
Calculation example 1:
$20,000 cost x 0.26 rebate = $5,200
In this example, you will receive an extra $5,200 back from the federal government.
Calculation example 2:
$15,000 cost x 0.26 rebate = $3,900
In this example, you will receive an extra $3,900 back from the federal government.
