California Form 3500A: Submission of Exemption Request Explained

Form 3500A, officially called Submission of Exemption Request, is a short document issued by the California Franchise Tax Board (FTB) that lets certain nonprofit organizations request state tax-exempt status based on a federal determination letter they’ve already received from the IRS. Instead of going through the FTB’s full exemption application process, qualifying organizations can use this streamlined form to get recognized as tax-exempt in California.

The key thing to understand about Form 3500A is that it isn’t a standalone application. It works alongside your federal IRS determination letter under Internal Revenue Code Section 501(c)(3). If the IRS has already approved your organization as exempt under that section, California allows you to piggyback on that approval rather than filing the longer Form 3500, which requires a much more detailed review of your organizational documents, activities, and finances.

Who Needs to File Form 3500A

This form is meant for nonprofit corporations, associations, or trusts that have received a federal 501(c)(3) determination letter and now want California state tax exemption from franchise or income tax. Common filers include charities, religious organizations, educational nonprofits, and other public-benefit entities that operate in California but were formed or recognized federally first.

If your organization has not yet received IRS approval under 501(c)(3), Form 3500A is not the right path. In that case, the FTB requires the longer Form 3500 application, which involves submitting bylaws, articles of incorporation, financial statements, and a detailed narrative of your activities. Form 3500A exists specifically to save time for groups that have already cleared the federal hurdle.

When to Use This Form

Organizations typically submit Form 3500A soon after receiving their IRS determination letter, since California doesn’t automatically recognize federal exempt status. Without filing this form (or the longer Form 3500), your organization could still owe California franchise tax or income tax despite being federally tax-exempt. Many newly formed nonprofits file this shortly after incorporation and federal approval to avoid unnecessary state tax liability in their first fiscal year.

There’s no strict statutory deadline tied to a specific date each year, but it makes sense to file as soon as possible after receiving IRS approval, since exemption is generally only effective from the date the FTB processes and accepts the submission, not retroactively in most cases.

How to Get and Complete Form 3500A

Form 3500A is available directly from the Franchise Tax Board as a fillable PDF, meaning you can type your information directly into the form fields before printing or submitting it electronically, depending on current FTB submission instructions. The form asks for basic identifying information: your organization’s name, California entity number, federal employer identification number (EIN), and the date of your IRS determination letter.

You’ll need to attach a copy of your IRS determination letter when you submit the form — this is the core piece of evidence the FTB uses to grant state exemption. Double-check that the legal name and EIN on your IRS letter match exactly what you enter on Form 3500A, since mismatches are one of the most common reasons submissions get delayed or rejected.

Nonprofit administrators juggling multiple state and federal filings often deal with parallel paperwork requirements. If your organization also has staff or contractors filing personal state returns, resources like the guide to Form IT-203-ATT for New York nonresidents or the overview of Form IT-201-ATT can be useful references for staff who split time or income between states.

Once the FTB reviews Form 3500A and confirms the IRS determination letter is valid and matches your organizational details, they’ll issue a letter confirming your California tax-exempt status. Keep this confirmation on file, since it’s often requested by donors, grant-making foundations, and banks when verifying your nonprofit’s standing.
