Understanding the California nonprofit sales tax exemption is critical for charities, foundations, and educational institutions that sell goods or host fundraising events. Many assume their 501(c)(3) status automatically exempts them from sales tax—but California law doesn’t work that way. The state grants exemptions only for specific activities, items, or transactions that meet narrow statutory criteria. Without proper documentation or awareness, even well-meaning nonprofits can face unexpected tax liabilities or audits. \
In this guide, we’ll break down California’s exemption rules, required forms, and compliance pitfalls. For organizations seeking hands-on guidance, Hands Off Sales Tax (HOST) helps nonprofits simplify compliance and stay audit-ready.
The Baseline: Why Nonprofits Don’t Automatically Qualify
Nonprofits in California sometimes assume that their 501(c)(3) or charitable status automatically grants them a sales tax exemption. That assumption, however, is incorrect. The law is explicit: “there are no statutory exemptions from the sales or use tax merely because the user is a nonprofit organization.”
No Blanket Exemption Under Law
CDTFA’s resources reinforce this principle: while nonprofits may enjoy exemptions in income or property tax, California does not provide a general exclusion from sales and use tax for nonprofit status alone. Any relief must come through specific statutes or regulations, not broad nonprofit privilege.
Sales Tax vs. Use, Income, and Property Exemptions
- Sales Tax: Imposed on retail sales of tangible personal property unless a specific exemption applies.
- Use Tax: Applies to purchases made out-of-state or untaxed sales used in California. Nonprofits may owe use tax if no sales tax was collected.
- Income Tax & Property Tax Exemptions: These are separate regimes. Many nonprofits are exempt from income tax under federal/state law. Some also qualify for a welfare exemption for property tax under R&T Code § 214, but that doesn’t translate to sales/use tax relief.
Because of these distinctions, even nonprofits must treat sales and use taxes like any other entity—register, collect, and remit unless a specific legal exception applies.
Specific Exemptions & Exclusions Available to Nonprofits
Although California provides no blanket sales tax exemption for nonprofits, the law does carve out specific exemptions and exclusions under narrow circumstances.
Charitable Sales & Welfare Exemption (§ 6375)
Under Rev. & Taxation Code § 6375, sales by charitable organizations engaged in relief of poverty or distress may be exempt if the organization qualifies for the “welfare exemption.”
- This applies when tangible personal property is sold or donated in furtherance of charitable purpose.
- However, normal office supplies or administrative goods generally remain taxable.
Charitable Organization Regulations (Regulation 1570)
Regulation 1570 provides additional criteria, such as requiring the organization to hold the welfare exemption on the retail location tied to the seller’s permit.
Exemptions for Newspapers, Periodicals & Art Leases
- Leases of original artwork may be exempt when both parties are nonprofit.
- Nonprofits distributing newspapers or periodicals can claim an exemption under Regulation 1590 via a special exemption certificate.
Situational Exclusions & Resale of Donated Goods
- Sales of donated goods by nonprofits (such as thrift stores) may qualify as resale—subject to proper resale certifications and rules.
- Inter-organizational transfers may be excluded when one nonprofit sells to another under qualifying conditions.
- The key is to follow statutory, regulatory, and documentation rules precisely—if conditions are not met, the exemption fails.
Step-by-Step Application & Documentation Process
Getting an exemption—or an eligibility review—in California requires more than belief; it demands documentary proof and procedural rigor. Here’s how nonprofits should approach it.
Pre-Application Eligibility Checklist
- Confirm you’re recognized under 501(c)(3) (or equivalent) for tax-exempt purposes.
- Verify your California state records (e.g. registering with the Franchise Tax Board).
- Assess whether your planned sales or activities potentially fall under qualified exemptions or exclusions (e.g. sales for relief of poverty).
Forms, Agencies & Supporting Documents
- The CDTFA’s “Nonprofit Organizations” guide outlines that when applying, you must send a written request or application to have your eligibility reviewed.
- Typical supporting documents include:
• IRS exemption letter
• Articles of incorporation and bylaws
• Mission statements or charitable purpose statements
• Financial statements or budgets showing intended use of proceeds
• Welfare exemption status if applicable under property tax code (for some special relief exemptions) - In some cases, CDTFA issues a verification letter confirming which sales or purchases may be exempt and what evidence must be furnished to suppliers.
Application Timeline & Approval Expectations
- Processing may take a few weeks to several months, depending on complexity and completeness of the request.
- If your application lacks required documentation, CDTFA may request additional information or deny the review.
- A verification letter will specify which activities qualify and any limitations.
Maintaining Exemption Status
- Even after approval, retain all supporting documents and the verification letter.
- Renew or revisit your exemption status if your mission or sales model changes.
- Be ready for CDTFA audits of your exempt sales, which may require you to show consistency and proper usage.
This process ensures that nonprofits both apply credibly and maintain a defensible position if CDTFA or auditors later question exemption claims.
Pitfalls, Edge Cases & Common Mistakes
Even when nonprofit status feels like a shield, California law contains many traps and ambiguous zones. Below are frequent pitfalls nonprofits fall into — and how to avoid costly missteps.
Event Sales, Auctions & Fundraisers
Many nonprofits assume fundraising events are exempt. Yet per Section 165.0000, gross receipts from auctions held to benefit nonprofits are not generally exempt from sales tax. Nonprofits acting as auctioneers must collect tax on the final bid if tangible property is involved. (E.g. auction board items)
Selling Tangible Goods
If your nonprofit sells tangible items (merchandise, crafts, books), those sales are taxable unless a specific exemption applies. Nonprofit status alone doesn’t exempt you.
Bundling Taxable & Non-Taxable Items
Combining a nontaxable service with a taxable good in one invoice can cause the entire transaction to become taxable (a bundling issue). To avoid this, itemize goods and services separately on the invoice so taxable parts are clear.
Donated Merchandise & Resale Complexities
Thrift stores operated by nonprofits can qualify for exemption under R&T Code § 6363.3, but only if at least 75% of net income supports medical or social services to chronically ill individuals. If those conditions are not strictly met, sales are taxable. Also, improper use of resale certificates on donated goods purchases can trigger liability.
Use Tax on Purchases
Nonprofits may owe use tax on out-of-state purchases or items used internally if no sales tax was paid. Use tax liability applies when you withdraw from inventory or fail to pay tax.
Compliance & Audit Defense Posture for Nonprofits
Nonprofits must treat sales and use tax compliance—and potential audits—as serious obligations. The right posture can make the difference between manageable review and costly assessments.
Essential Records & Documentation
Maintain complete and orderly records including:
- Sales invoices and receipts
- Gift or donation acknowledgments
- Resale certificates and exemption documents
- Supporting documents (mission statements, governing documents, IRS exemption letters)
According to CDTFA’s Nonprofit Organizations guide, nonprofits must keep records showing all claimed exemptions and exclusions.
Periodic Internal Reviews & Gap Assessments
- Conduct routine internal audits to detect discrepancies or missing documentation before CDTFA does.
- Use reconciliations between financial systems and tax filings to identify gaps.
- Review exemption certificates for validity (dates, completeness) and retire or re-collect expired ones.
HOST often recommends quarterly “health checks” to flag risk before it escalates.
Responding to a CDTFA Audit
- Expect auditors to test sampling, review your exemption claims, and request workpapers. CDTFA’s audit manuals emphasize auditing deductions and postings.
- Defense arguments may include challenging sample representativeness, justifying exemptions with clear documentation, and demonstrating consistent recordkeeping.
- A solid response will combine factual support with procedural objection to flawed audit methodology.
With robust internal controls, defensible documentation, and expert backup, nonprofits can reduce audit risk and respond more effectively if an examination occurs.

Frequently Asked Questions (FAQs)
1. Are all nonprofits in California exempt from sales tax?
No. California does not offer a blanket sales tax exemption for nonprofits. Only specific transactions—such as those related to charitable, educational, or welfare purposes—may qualify under limited provisions in the Revenue and Taxation Code. Each exemption must be proven with proper documentation.
2. What types of nonprofit sales can be exempt?
Exemptions typically cover sales for relief of poverty, donations of food, and certain fundraising activities that meet strict statutory requirements. Organizations operating thrift stores, auctions, or merchandise sales must confirm eligibility under California’s specific rules before claiming any exemption.
3. How does a nonprofit apply for sales tax exemption in California?
A nonprofit must submit documentation to the California Department of Tax and Fee Administration (CDTFA), including its IRS 501(c)(3) letter, articles of incorporation, and mission details. CDTFA reviews these materials and may issue a verification letter confirming qualifying sales or purchases.
4. What records should nonprofits maintain for compliance?
Keep invoices, exemption certificates, donation receipts, resale records, and all correspondence with CDTFA. These records help substantiate exemption claims and form the backbone of your defense if audited. Missing documentation is one of the leading causes of failed exemption claims during audits.
