Illinois Convertible Promissory Note Overview

A convertible promissory note in Illinois is a debt instrument commonly used in startup financing that converts into equity upon a triggering event. As a security, it must comply with both federal regulations (SEC Rule 506 under Regulation D) and Illinois's state securities laws. The primary state exemption is: 815 ILCS 5/4 exemption.

Illinois requires Form D filing required when issuing convertible notes. The state provides enhanced protections for note holders through its securities regulatory framework. The interest rate must comply with Illinois's 9% usury limit, though most convertible note rates (2-8%) fall well below this threshold. Companies should work with an attorney familiar with Illinois securities law to ensure full compliance.

Securities Compliance in Illinois

When issuing convertible promissory notes in Illinois, you must comply with the state securities exemption (815 ILCS 5/4 exemption), file the required Form D filing required, ensure the interest rate stays within the 9% usury limit, and follow Illinois's investor protection requirements (enhanced protections). Federal Form D must be filed with the SEC within 15 days of the first sale. Our Illinois-specific template ensures compliance with both state and federal securities regulations.
