California nonprofits answer to the Attorney General's Registry of Charitable Trusts (RRF-1, CT-TR-1, initial CT-1 registration), the Franchise Tax Board (Form 199 or 199N), and — for federally funded organizations — the Uniform Guidance single audit regime. The state filings have moved deadlines and added forms repeatedly over the past five years; this FAQ reflects the current cadence and the cross-cutting interaction with federal grant compliance.
A Bay Area health-equity nonprofit with $4.2M in revenue submitted its Form 990 federal return on schedule and assumed the California state filings were tracked by the same outside CPA. Six months later, the AG Registry posted a delinquency status — the RRF-1 had never been filed, and the prior-year CPA audit had not been attached. A major California state contract was withheld pending Registry good standing. The organization spent three weeks remediating two years of missed filings and paying penalty fees that, once aggregated, exceeded the cost of the original filings several times over.
California compliance is straightforward in form and easy to miss in practice. The Attorney General’s Registry of Charitable Trusts requires annual RRF-1 filings from every registered organization regardless of revenue. The Franchise Tax Board requires annual Form 199 or 199N. Small organizations under $50,000 in gross revenue file the additional CT-TR-1. Organizations using commercial fundraisers file CT-694. And federally funded California nonprofits inherit the full Uniform Guidance regime when their federal expenditures cross the $1M single-audit threshold — see the practical guide to 2 CFR 200 for the federal layer.
Mid-sized nonprofits in this category typically inherit a tangle of restricted-fund histories: federal pass-throughs, state agency contracts, family-foundation grants, and partner funding stretching back many years. Migrating that history cleanly is not optional — auditors and program officers will ask questions that require a year-by-year reconstruction. Implementation timelines run six to ten weeks for organizations that scope the data inventory before signing. Cutting corners on migration to chase a fast launch usually surfaces gaps during the next single-audit cycle, and the cost of fixing those gaps after the fact is meaningfully higher than doing migration right at the start.
Plan accordingly, and require any vendor on the shortlist to demonstrate restricted-fund handling, grant tracking, and donor record migration on a representative sample of your actual historical data before you sign. Vendors that decline to demo on real data are filtering you out for a reason. The demo on your data is where the gaps surface — both the gaps in the vendor’s product and the gaps in your existing records that you will need to clean up regardless of which system you choose. Use that demo to set realistic expectations with the board and the audit committee about timeline and scope before contracts get signed.

Q&A
Does California require an audit at $500,000 like some other states?
No. California's audit threshold is $2,000,000 in gross revenue. State requirements should not be confused with funder or federal requirements, which often impose audit at lower revenue.
Q&A
Can a California nonprofit be registered with the IRS but not the AG Registry?
It can happen, but it is a violation. Federal 501(c)(3) status does not relieve a California organization of the AG Registry registration requirement, and operating without registration exposes the organization to enforcement action.
Q&A
How does Proposition 64 / cannabis revenue affect nonprofit compliance?
Cannabis-related revenue raises both unrelated business income (UBIT) issues at the federal level and licensing complications under California cannabis regulations. Nonprofits considering any cannabis-adjacent revenue should consult counsel before initiating the activity.
Frequently asked
Frequently Asked Questions
What is the RRF-1 and who has to file it?
Form RRF-1 is the Annual Registration Renewal Fee Report filed by every charity registered with the California Attorney General's Registry of Charitable Trusts. All organizations holding assets for charitable purposes in California must register and then file RRF-1 annually, regardless of whether contributions were solicited that year. The form sets a renewal fee scaled by gross annual revenue and asks a series of governance questions about transactions with insiders, loans, and significant compensation.
When is RRF-1 due?
RRF-1 is due 4 months and 15 days after fiscal year end — the same as the federal Form 990 (without extension). California grants extensions of up to 6 months, but the extension must be requested via the Registry's portal. Late filing triggers escalating late fees and ultimately delinquent or suspended status, both of which appear publicly on the Registry search and trigger funder due diligence flags.
What is CT-TR-1 and is it different from RRF-1?
CT-TR-1 is the Annual Treasurer's Report, required for California-registered organizations with gross revenue under $50,000 that do not file IRS Form 990 or 990-EZ. CT-TR-1 collects a basic financial summary in lieu of the full 990. Organizations above the $50,000 gross-revenue threshold file Form 990 (or 990-EZ) with the IRS and attach a copy to RRF-1; they do not file CT-TR-1. The form numbers create confusion: small organizations file CT-TR-1 + RRF-1; larger organizations file Form 990 + RRF-1.
When is an audited financial statement required for California filings?
Under California Government Code §12586(e)(1), nonprofits with gross revenue of $2,000,000 or more must obtain an independent CPA audit and submit it with the RRF-1. Organizations under that threshold may file without an audit (subject to other audit obligations from federal grants, foundation requirements, or state contracting). The $2M threshold has been stable for several years but check Government Code §12586 and the AG Registry guidance before contracting.
What is initial registration with the AG Registry of Charitable Trusts?
Every charitable organization holding assets in California for charitable purposes must register with the AG Registry within 30 days of first receiving property. Initial registration uses Form CT-1 and requires a copy of the founding documents, IRS determination letter (if available), and other supporting material. Organizations that wait until they have substantial assets to register face penalties and complications during initial filing — register at formation.
How does Form 199 differ from RRF-1?
Form 199 is the California Franchise Tax Board's annual return for tax-exempt organizations — it is filed with FTB, not with the AG Registry. RRF-1 is filed with the AG Registry. Both are annual; both are required for most California nonprofits; they go to different agencies and serve different purposes (FTB is tax; AG is governance). FTB Form 199N (e-Postcard) applies to organizations with gross receipts normally $50,000 or less. Filing one does not relieve you of the other.
How does California single-audit interaction work?
California does not have a separate state single-audit statute layered on top of the federal Uniform Guidance, but state pass-through dollars in many California grant programs (CDSS, DHCS, CalOES) flow federal funds and therefore impose Uniform Guidance compliance on the subrecipient. If your federal expenditures aggregate to $1,000,000 or more in a fiscal year (the post-2024 threshold), you must conduct a single audit under 2 CFR 200 Subpart F and submit it to the Federal Audit Clearinghouse. State pass-through funds count toward that threshold.
What is California's charitable solicitation registration requirement?
California consolidates charitable solicitation oversight into the AG Registry of Charitable Trusts — there is no separate solicitation license. Once registered with the Registry and current on RRF-1 filings, an organization may solicit contributions in California. Out-of-state organizations soliciting California donors must register with the Registry just as in-state organizations do.
When does my California nonprofit need to file Form CT-694?
Form CT-694 (Annual Financial Solicitation Report) is required of organizations using commercial fundraisers in California. It collects detail on professional fundraising contracts, gross receipts, fundraiser fees, and net proceeds. Organizations that do not contract commercial fundraisers do not file CT-694. Both the nonprofit and the fundraising firm have separate filing obligations — mismatches between the two filings are an audit trigger.
What is the penalty for late RRF-1 filing in California?
The California AG assesses late fees that escalate based on how late the filing is and the size of the organization. Continued non-filing results in delinquent status, then suspended status, then loss of tax-exempt status under California law. Suspended organizations cannot legally solicit contributions in California and may be administratively dissolved. Restoring registration is more involved than filing on time — a one-year delinquency that is corrected typically resolves with a fee; a multi-year delinquency requires a formal reinstatement process.
Does my California nonprofit need to file CT-TR-1 if we file Form 199N?
Yes. Form 199N is filed with the FTB; CT-TR-1 is filed with the AG Registry. Small California nonprofits typically file Form 199N (FTB) and CT-TR-1 (AG Registry) plus RRF-1 (AG Registry) every year. The forms cover overlapping financial information but go to different agencies and are not substitutes.
How do I withdraw a California charitable registration?
To withdraw, file a final RRF-1 indicating final filing, submit a request for withdrawal in writing to the Registry, and resolve any outstanding fees or filings. Organizations dissolving in California must follow the dissolution process under the Nonprofit Corporation Law and distribute remaining charitable assets in compliance with §17510.5 of the California Business and Professions Code (the irrevocable charitable purpose requirement).
