These reports must be filed every two years for both nonprofit and for-profit businesses. The filings are due during the anniversary month of your business's formation or the anniversary month in which you were granted authority to do business in the state. As a courtesy, the Secretary of State will send a reminder notice the month your report is due.
If you own the business entirely by yourself and plan to be responsible for all debts and obligations, you can register for a sole proprietorship. Be warned that this route can directly affect your personal credit. Alternatively, a partnership, as its name implies, means that two or more people are held personally liable as business owners. You don't have to go it alone if you can find a business partner with complementary skills to your own. It's usually a good idea to add someone into the mix to help your business flourish.
