Nonprofit Sales Tax Compliance in California: A Complete Guide

May 12, 2025 | Blog Posts, Compliance, Sales Tax

If you’ve ever wondered do non profits pay sales tax in California, the answer is more nuanced than most expect. Unlike income tax exemptions granted to 501(c)(3) organizations, California does not offer a blanket sales tax exemption to nonprofits. This means many charitable organizations are still required to collect and remit sales tax on applicable transactions. Failing to comply can lead to fines, audits, and reputational risk. 

This guide walks you through the sales tax landscape for nonprofits in California. And if you’d rather not navigate it alone, Hands Off Sales Tax (HOST) is here to help you stay fully compliant, effortlessly.

Understanding Sales and Use Tax in California

In California, the sales and use tax system applies broadly to the sale and use of tangible personal property, with specific implications for nonprofit organizations.

Definition and Scope

Sales Tax is imposed on retailers for the privilege of selling tangible personal property at retail in California. Use Tax complements sales tax and applies to the storage, use, or consumption of tangible personal property purchased from out-of-state sellers without California sales tax. “Tangible personal property” refers to items that can be seen, weighed, measured, felt, or touched, such as furniture, clothing, and artwork.

Application to Nonprofits

Nonprofit organizations in California are generally subject to the same sales and use tax laws as other entities. This means that unless a specific exemption applies, nonprofits must collect sales tax on their sales of tangible personal property and pay use tax on taxable purchases.

Common scenarios where sales tax applies to nonprofits include:

  • Fundraising Sales: Selling merchandise like t-shirts, books, or baked goods.
  • Event Admissions: Charging for entry to events where tangible goods are provided.
  • Auctions: Selling donated items during fundraising auctions.

It’s important for nonprofits to understand that holding a federal tax-exempt status does not automatically exempt them from California sales and use taxes. They must ensure compliance by obtaining the necessary permits and understanding the specific exemptions that may apply to their activities .

Exemptions and Special Provisions for California Nonprofits

While California does not provide a blanket sales tax exemption for nonprofit organizations, certain specific exemptions and provisions can apply under defined circumstances.

Specific Exemptions Available

Nonprofits may qualify for sales tax exemptions in the following scenarios:

  • Occasional Fundraising Events: Sales at infrequent fundraising events, such as rummage sales, bazaars, or community events, may be exempt from sales tax.
  • Sales of Donated Goods: Items donated to the nonprofit and subsequently sold can be exempt, provided the donor did not receive any consideration and the items were not purchased for resale.
  • True Donations: Monetary contributions where the donor does not receive merchandise or services of equal value in return are not considered sales and are not subject to sales tax.
  • Sales of Certain Tickets: Tickets sold for events where the ticket price includes food or beverages may be exempt under specific conditions.

Criteria for Exemptions

To qualify for these exemptions, nonprofits must meet certain criteria:

  • Charitable Purpose: The organization must be formed and operated exclusively for charitable purposes.
  • Welfare Exemption Qualification: The organization should qualify for the welfare exemption from property taxation on the retail site where sales occur.
  • Use of Proceeds: The proceeds from sales must be used exclusively in furtherance of the organization’s charitable activities.

It’s essential for nonprofits to maintain proper documentation and ensure compliance with all conditions to benefit from these exemptions.

Obtaining a Seller’s Permit

In California, nonprofit organizations engaging in the sale of tangible personal property are generally required to obtain a seller’s permit, even if the sales are not taxable. This requirement ensures compliance with the state’s sales and use tax laws and facilitates proper tax reporting and remittance.

Requirement for Nonprofits

Nonprofits must obtain a seller’s permit if they:

  • Sell goods or merchandise in California, regardless of whether the sales are taxable.
  • Conduct three or more fundraising sales events per year.
  • Engage in continuous taxable sales activities.

Even if all sales are nontaxable, a seller’s permit is generally required.

Application Process

Obtaining a seller’s permit is a straightforward process:

  1. Online Registration: Visit the CDTFA Online Services Registration page.
  2. Information Required: Prepare necessary information, including:
    • Organization’s name and address.
    • Federal Employer Identification Number (FEIN).
    • Description of business activities.
    • Estimated monthly sales.
  3. Permit Type: Determine the appropriate permit:
    • Regular Seller’s Permit: For organizations conducting ongoing sales.
    • Temporary Seller’s Permit: For organizations holding sales events lasting less than 90 days.
  4. Submission: Complete and submit the application online.
  5. Post-Approval: Upon approval, the CDTFA will issue the seller’s permit, which must be displayed at the place of business.

Collecting and Remitting Sales Tax

For nonprofit organizations in California, understanding when and how to collect and remit sales tax is crucial to ensure compliance with state regulations.

When to Collect Sales Tax

Nonprofits are generally required to collect sales tax when selling tangible personal property, regardless of whether the items are new, used, donated, or homemade. Common scenarios include:

  • Fundraising Events: Sales at events like rummage sales, bazaars, or community events.
  • Ticket Sales: Selling tickets that include food, beverages, or other physical products.
  • Auctions: Selling merchandise through live, silent, or online auctions.

It’s important to note that even if the sales are for fundraising purposes, they may still be taxable unless a specific exemption applies. 

Filing Returns and Remittance

Once sales tax is collected, nonprofits must remit it to the California Department of Tax and Fee Administration (CDTFA). The process involves:

  1. Filing Frequency: Determine your filing frequency (monthly, quarterly, or annually) based on your organization’s sales volume.
  2. Online Filing: File your sales and use tax return electronically through the CDTFA’s Online Services Portal.
  3. Reporting Sales: Report all sales, including taxable and nontaxable transactions. You can claim deductions for exempt sales where applicable.
  4. Payment: Remit the tax due using one of the CDTFA’s accepted payment methods, such as ACH debit, credit card, or paper check. Detailed instructions are available in the CDTFA-401-INST.

Record-Keeping and Compliance

Maintaining accurate and comprehensive records is essential for nonprofit organizations in California to ensure compliance with sales and use tax regulations. Proper documentation not only facilitates accurate tax reporting but also prepares organizations for potential audits by the California Department of Tax and Fee Administration (CDTFA).

Maintaining Proper Records

Nonprofits holding a California seller’s permit are required to retain business records that verify the accuracy of their sales and use tax returns. These records should be kept for a minimum of four years and include:

  • Sales Records: Invoices, receipts, and cash register tapes detailing all sales transactions.
  • Purchase Records: Invoices and receipts for all purchases, especially those for resale or exempt items.
  • Tax Returns: Copies of filed sales and use tax returns and related worksheets.
  • Exemption Documentation: Resale certificates and other documents supporting tax-exempt sales.

Audit Preparedness

To prepare for potential audits:

  • Organize Records: Maintain records in an orderly manner, making them easily accessible for review.
  • Separate Sales: Clearly distinguish between taxable and nontaxable sales in your records.
  • Retain Supporting Documents: Keep all documents that support deductions or exemptions claimed.
  • Regular Reviews: Periodically review records to ensure completeness and accuracy.

The CDTFA provides guidance on audit procedures in their Audit Manual. Being well-prepared can facilitate a smoother audit process and demonstrate your organization’s commitment to compliance.

Common Mistakes and How to Avoid Them

Navigating California’s sales tax landscape can be particularly challenging for nonprofits. Misunderstandings and oversights can lead to significant compliance issues. Here are some prevalent mistakes and strategies to prevent them:

Misconceptions About Exemptions

  • Assuming Blanket Exemption: Many nonprofits mistakenly believe that their 501(c)(3) status automatically exempts them from sales tax obligations. In California, there is no general exemption for nonprofits; tax applies unless a specific exemption is granted.
  • Overlooking Specific Exemptions: Certain sales, such as occasional fundraising events or sales of donated goods, may be exempt. However, these exemptions have strict criteria and limitations.

Errors in Tax Collection and Remittance

  • Failing to Obtain a Seller’s Permit: Nonprofits engaging in sales must obtain a seller’s permit from the California Department of Tax and Fee Administration (CDTFA), even if the sales are infrequent.
  • Incorrectly Applying Sales Tax: Charging or not charging sales tax without proper assessment can lead to liabilities. It’s essential to determine the taxability of each transaction accurately.
  • Inadequate Record-Keeping: Maintaining detailed records of sales, exemptions, and tax filings is crucial. Poor documentation can hinder audit preparedness and compliance.

To mitigate these risks, nonprofits should:

  • Regularly review and understand applicable sales tax laws and exemptions.
  • Ensure proper registration and obtain necessary permits.
  • Maintain comprehensive records and documentation.
  • Seek guidance from tax professionals like HOST, or consult resources like the CDTFA’s Tax Guide for Nonprofit Organizations.

By proactively addressing these areas, nonprofits can enhance compliance and reduce the risk of penalties.
