Colorado Convertible Promissory Note Overview

A convertible promissory note in Colorado 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 Colorado's state securities laws. The primary state exemption is: CRS 11-51-308 exemption.

Colorado 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 Colorado's 45% usury limit, though most convertible note rates (2-8%) fall well below this threshold. Companies should work with an attorney familiar with Colorado securities law to ensure full compliance.

Securities Compliance in Colorado

When issuing convertible promissory notes in Colorado, you must comply with the state securities exemption (CRS 11-51-308 exemption), file the required Form D filing required, ensure the interest rate stays within the 45% usury limit, and follow Colorado's investor protection requirements (enhanced protections). Federal Form D must be filed with the SEC within 15 days of the first sale. Our Colorado-specific template ensures compliance with both state and federal securities regulations.

Colorado Usury Warning

Colorado's usury limit is 45%. Charging interest above this rate can render your promissory note unenforceable and may subject the lender to penalties under Colorado law. Our template automatically validates your interest rate against Colorado's current limits.
