When registering and operating a business in California, understanding the California Secretary of State (SOS) file number is crucial. This unique identifier, issued upon registration, plays a significant role in legal filings, tax compliance, and business operations. Whether you’re forming a corporation or running a limited liability company (LLC), knowing how to find, use, and manage your SOS file number is key to staying compliant.
What Is a California Secretary of State File Number?
File numbers are assigned to all entities in the state of California by the Secretary of State. This can be found in the LLC form that was submitted when applying for a limited liability corporation. It’s used to distinguish entities, streamline state records, and facilitate tax and legal filings.
Typically, businesses will either have a seven-digit corporation number or a 12-digit file number. They can call the office of the Secretary of State to see which one they have if they don't have their original application form. The ID number and type can also be found on the California Secretary of State's website.
Types of State File Numbers
California assigns different types of file numbers depending on the entity type:
- Secretary of State (SOS) Number: A 12-digit number starting with “19” or “20,” commonly assigned to corporations.
- California Corporation Number: A 7-digit number beginning with “C,” designated for corporate entities.
- LLC Temp Number: A 9-digit number starting with “0,” typically issued for LLCs during the registration process.
Each number format serves a specific function and is essential for ensuring accurate business identification. All corporations in California have an SOS file number, regardless of whether they are a C corporation or an S corporation. They'll receive this after they file the Articles of Incorporation with the Secretary of State when they are forming their corporation.
Choosing an S corporation status is a tax election that is filled with the Internal Revenue Service and isn't related to the corporation's SOS File Number. The original incorporation stays valid.
Why Is the California State File Number Important?
The SOS file number is more than just an identifier—it’s integral to a business’s legal and operational framework.
- Legal and Tax Filings: It’s required for submitting state tax returns, filing annual reports, and processing other legal documents.
- Entity Differentiation: The file number helps the state maintain accurate records by distinguishing between businesses with similar names.
- Compliance Requirements: Many compliance activities, such as paying franchise taxes or filing Statements of Information, mandate the inclusion of the file number.
Failure to use the correct file number can lead to delays, penalties, or even non-compliance issues.
How to Receive a California Secretary of State File Number
When a California business tax return is filed, it is required to put the filing number on the tax forms. The filing number is not the same as the tax identification number. This is a separate number that the California Secretary of State assigned when the company registered with the office.
If the number needs to be located, the owner can look at paperwork or receipts they received from the California Secretary of State from the year the business was registered. The owner can also ask the office of the Secretary of State to look up the filing number but will need to give the business name, address, and tax ID number.
