Washington Convertible Promissory Note Overview

A convertible promissory note in Washington 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 Washington's state securities laws. The primary state exemption is: RCW 21.20 exemption.

Washington 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 Washington's 12% usury limit, though most convertible note rates (2-8%) fall well below this threshold. Companies should work with an attorney familiar with Washington securities law to ensure full compliance.
