Illinois Financial Disclosure is a system put in place to increase transparency and accountability in government spending and operations. It requires certain public officials and candidates to make public certain financial information, such as income, investments, and liabilities.

Gift Ban: This requires public officials and candidates to report any gifts received over a certain value. 3.
