What Is Form CT-1 for California Nonprofits, and When Do You File It?

New nonprofit founders in California quickly discover that operating in the state means dealing with more than just the IRS. California has its own registration system for charitable organizations, and the first form that starts the entire process is one that many founders have never heard of until they are already behind on it. Form CT-1 is not optional; it is not a technicality, and getting it wrong at the beginning creates compliance problems that can follow your organization for years.

What Is Form CT-1?

Form CT-1, officially called the Initial Registration Form, is the document used to register a charitable organization with the California Attorney General’s Registry of Charitable Trusts. It is the entry point for all charities that plan to operate or solicit donations in California.

When a nonprofit corporation is formed in California, the state’s Secretary of State receives the articles of incorporation. But incorporation alone does not register the organization with the Attorney General’s Registry. That step requires a separate filing, and Form CT-1 is that filing. Without it, your organization is not properly registered as a charity in California, even if you are already incorporated and even if your IRS 501(c)(3) application is in progress.

The form collects basic information about the organization, including its legal name, address, date of incorporation, fiscal year end, and the names of its officers and directors. It also requires a copy of your articles of incorporation and your bylaws, and it must be accompanied by a filing fee.

Who Must File Form CT-1?

Most public benefit corporations, mutual benefit corporations holding assets for charitable purposes, and unincorporated associations operating for charitable purposes in California must file Form CT-1.

The requirement also applies to out-of-state organizations that solicit donations from California residents or operate charitable programs in the state. If your nonprofit is headquartered elsewhere but runs programs in California or sends fundraising communications to Californians, you are likely required to register.

There are limited exemptions. Religious corporations organized primarily for religious purposes and certain educational institutions affiliated with accredited schools may be exempt. However, exemptions must be affirmatively claimed and are not assumed.

When Is Form CT-1 Due?

California requires organizations to file Form CT-1 within 30 days of initially receiving assets, commencing operations, or soliciting donations in the state, whichever happens first. For most nonprofits, this means the clock starts running very early in the organization’s life, often before founders have even opened their bank account.

Missing this deadline means the organization is operating as an unregistered charity, which can lead to enforcement action by the Attorney General’s office. Delinquent organizations may face fines, financial disclosure requirements, and restrictions on fundraising until they are restored to good standing.

What Comes After Form CT-1?

Filing Form CT-1 initiates your registration, but it does not end your compliance obligations. Each year after the initial registration, California charities must file an RRF-1, or Annual Registration Renewal Fee Report, to keep their registration active. The RRF-1 requires updated financial information and a renewal fee based on your organization’s gross revenue.

Organizations with higher revenue thresholds are also required to submit audited or reviewed financial statements prepared by a licensed CPA. The California Attorney General Charities portal provides current threshold information and form instructions.

Keeping both the initial CT-1 and subsequent RRF-1 filings current is what gives your organization legal standing to solicit donations and receive charitable contributions in California.

Practical Steps for New California Nonprofits

Understanding Form CT-1 is part of a larger compliance picture. If you are in the early stages of forming a nonprofit, there are several steps to complete in sequence.

First, incorporate with the California Secretary of State. Next, file Form CT-1 with the Attorney General’s Registry as soon as your organization receives assets or begins operations. At the same time, prepare and submit your IRS Form 1023 or Form 1023-EZ to apply for federal tax-exempt status. If you’re researching how to set up a 501(c)(3) in Texas, for example, the basic federal tax-exemption process still involves applying to the IRS, but the state-level registration and compliance requirements will differ from California’s. Finally, register with the California Franchise Tax Board to establish your state-level tax-exempt status and set up a compliance calendar for annual RRF-1 filings going forward.

Each of these steps builds on the previous one, and skipping any of them creates gaps that tend to surface at the worst possible time.

Founders who want to understand how to start a nonprofit in Texas will find that Texas has its own distinct formation and registration requirements, and working through those alongside organizations like Beacon Nonprofit’s state-specific guidance can help clarify which steps apply in each state.

Conclusion

Form CT-1 is where charitable registration in California begins, and it is due sooner than most founders expect. Getting it filed on time, along with your articles of incorporation and bylaws, sets your organization up for the annual compliance cycle that follows. Missing it puts your charitable status at risk from the very start.
