Individuals

SIGMA VSS provides one stop for individuals to maintain their address and bank account information.  SIGMA VSS includes all your payments made by the State (by check or direct deposit), and sends emails to inform you of important information. If you are a sole proprietor, you can also see your contracts and business and grant opportunities. SIGMA VSS improves online security and protection of personal information. You can easily see and maintain your information 24 hours a day, 7 days a week, outside of standard maintenance, in SIGMA VSS through a secure connection.  For specific instructions, see the links below.
