What Are Tax Exemptions in Illinois?

Tax exemptions in Illinois reduce or eliminate liability for property taxes, sales taxes, or income taxes for qualifying individuals, organizations, and businesses. They are designed to provide relief for seniors, veterans, disabled persons, low-income households, nonprofits, and specific industries like manufacturing and agriculture.

Exemptions are claimed through specific forms filed with county offices (for property) or provided to sellers (for sales tax). Illinois does not conform fully to federal tax rules, so state-specific rules apply.
