Relevant Laws
California Uniform Partnership Act (UPA)
This is the primary law governing partnerships in California. It defines what constitutes a partnership, the rights and duties of partners, and how partnerships are formed and dissolved. Understanding this act is essential when setting up any partnership in California.
California Partnership Filing Requirements
While general partnerships don't require formal registration in California, filing a Statement of Partnership Authority with the Secretary of State is recommended. This filing puts the public on notice of your partnership and specifies who has authority to bind the partnership.
California Fictitious Business Name Laws
If your partnership will operate under a name different from the surnames of all partners, you must file a Fictitious Business Name Statement (also known as 'doing business as' or DBA) with the county clerk in each county where you have a place of business.
California Business License Requirements
Most businesses in California, including partnerships, need to obtain appropriate business licenses and permits. Requirements vary by location and business type, so you'll need to check with your city and county.
California Tax Requirements for Partnerships
Partnerships in California must file Form 565 (Partnership Return of Income) annually with the Franchise Tax Board. While partnerships themselves don't pay income tax, they must report income that passes through to partners, who pay taxes individually.
California Partnership Agreement Requirements
While not legally required, having a written partnership agreement is strongly recommended in California. Without one, the default provisions of the California Uniform Partnership Act will govern your partnership, which may not align with your intentions.
