What It Is

In Illinois, solar energy systems do not increase your property tax assessment even though they may increase the value of your property. This prevents higher property taxes due to solar installation.

How It Works

  • After solar installation, file the required forms with your county assessor.
  • Your solar system is valued separately, typically at a lower assessment basis.

Who It Helps

  • Commercial property owners.
  • Agricultural facilities.
  • Other taxable properties.

Why It Matters

This exemption protects your bottom line by preventing additional property taxes that could negate solar savings.
