Handling California state tax matters can be complicated, especially if facing an audit, arranging a payment plan, or managing taxes for a business or trust. The state allows you to appoint someone to represent you using a legal tool known as the California Tax Power of Attorney form. This legal document, called a POA declaration, authorizes a trusted person—your attorney-in-fact—to act on your behalf before the Franchise Tax Board (FTB). They may access your confidential account information, receive notices, discuss your case, and address matters related to tax compliance.
This guide explains how to properly complete and submit the FTB's official form, FTB 3520-PIT or 3520-BE, depending on your filing status. We'll cover who can use these forms, what powers they grant, how long they last (typically six years), and the following methods for submission—online through MyFTB or by mail. Whether you're a taxpayer, a business company, or someone unable to manage taxes due to health or financial circumstances, this article will help you make informed decisions when assigning authorization through a power of attorney.
A power of attorney (POA) is a legal document that allows one person—the taxpayer—to authorize another individual or professional to act on their behalf. This authority is explicitly used in California tax cases, such as communicating with the Franchise Tax Board (FTB), accessing account information, and managing filings, payments, and disputes—the individual you designate as your attorney-in-fact obtains access to information and rights typically reserved for you.
A California tax POA is strictly limited to matters related to the state's tax system, unlike a general financial POA or one created for medical treatment decisions. For example, a general durable POA might give someone control over your finances, property, or healthcare, but the FTB wouldn't accept it for tax representation. California requires a POA declaration that is tax-specific and submitted on the same form designed for the Franchise Tax Board. This process ensures the state agency can verify the authorization is valid and appropriate for the situation.
The Franchise Tax Board accepts only its versions of power of attorney forms—form FTB 3520-PIT and FTB 3520-BE. These various forms differ based on who is filing:
Both forms serve the same core function: to grant another individual the legal authority to obtain and manage confidential information, submit other documents as needed, and handle interactions with the FTB on behalf of the taxpayer. Each form requires signatures, the designation of specific tax years, and clearly defined authorization scopes.
Many taxpayers mistakenly assume that federal tax forms can be used for state purposes. However, California explicitly rejects IRS Form 2848, the federal power of attorney form commonly used for dealings with the IRS. Submitting this form to the California Franchise Tax Board (FTB) will result in a denial of representation because the state has established its procedures and documentation requirements. To avoid delays, submitting the correct state-issued legal document is crucial.
California requires a state-specific POA declaration because its probate code, regulations, and administrative systems differ significantly from federal processes. The state exercises its authority regarding representation, privacy rights, and access to confidential information, so it mandates the use of its official forms. These forms are designed to comply with California law and ensure the proper authorization is in place to protect the taxpayer and their account information.
The only accepted forms are FTB 3520-PIT and FTB 3520-BE. Each is tailored for different taxpayer types. Individuals, fiduciaries, and estates use FTB 3520-PIT, while FTB 3520-BE applies to company structures such as corporations, partnerships, and LLCs. Regardless of your situation, using one of these various forms is not just a best practice—it's a requirement. Failing to do so can result in processing delays or the inability of your attorney-in-fact to represent you legally in tax matters.
There are many situations where filing a California Power of Attorney form is helpful and necessary. If you're dealing with the Franchise Tax Board (FTB) and need someone to represent you—whether you're temporarily unavailable, overwhelmed by tax issues, or relying on a professional for assistance—a POA authorizes them to handle your case correctly. Submitting this form ensures that your chosen attorney-in-fact can communicate with the FTB, access confidential information, and help resolve issues efficiently and legally.
Here are ordinary circumstances where a California taxpayer should consider filing a POA declaration:
Using a POA form proactively ensures continuity in managing your state taxes, even when you cannot handle them directly.
If you’re preparing to authorize someone to act on your behalf with the California Franchise Tax Board (FTB), understanding the difference between the two official Power of Attorney (POA) forms—FTB 3520-PIT and FTB 3520-BE—is crucial. Each form targets different types of taxpayers, and using the wrong one can delay processing or limit your representative’s access.
Choosing the right form—based on whether you’re acting as an individual or a business—is the key to a smooth authorization process with the California FTB. Always double-check your entity type and supporting documentation before filing.
A California power of attorney gives the appointed attorney-in-fact the ability to legally act on behalf of the taxpayer in dealings with the Franchise Tax Board (FTB). This includes reviewing private tax information, speaking with the agency, and completing specific tax-related tasks. The precise authorization depends on the selections made in the submitted POA declaration.
The POA allows your representative to obtain and review your confidential information maintained by the FTB. This access includes the following:
Once the POA is active, your representative has the legal right to represent you in formal proceedings with the FTB. These include:
California's forms FTB 3520-PIT and 3520-BE allow you to grant your agent additional powers, but only if you select these explicitly on the form. These optional authorizations include the following:
Filing a California Power of Attorney form correctly ensures your attorney-in-fact has the necessary authorization to handle your tax matters. Below is a simplified breakdown for each form: FTB—PIT for individuals and fiduciaries, and BE for business entities.
Provide your legal name, SSN or ITIN, and mailing address. Fiduciaries must list the estate or trust name and FEIN.
List each authorized person with contact info and professional credentials (e.g., CPA, EA, or attorney).
Indicate whether the POA applies to all years or lists up to four specific tax years.
You may authorize your agent to sign tax returns, receive refund checks, or waive statute limitations.
Choose between full and limited access to your account information.
Use an original ink signature. If you are signing on behalf of someone else under a general or durable power of attorney, please attach the relevant legal documents.
Include the legal business name, address, and at least one ID number (e.g., CA SOS number or FEIN).
List individual agents (not firms) with credentials and contact information.
Use the mm/dd/yyyy format for up to four specific periods or authorize them all.
Choose whether to grant authority for settlement agreements or receive notices.
Grant full or limited online access to your business's tax account.
A qualified officer, such as a chief financial officer, must sign and list their title.
After completing your POA declaration, you must submit it to the Franchise Tax Board (FTB) using one of two accepted methods: online via MyFTB or by mail. Submitting the form correctly and all required signatures and supporting documentation ensures your authorization is processed without delays.
The fastest and most secure option is submitting your form FTB 3520-PIT or 3520-BE through MyFTB.
Paper filing is available if you cannot use MyFTB or prefer physical submission.

A power of attorney granted to a representative remains active until it is revoked, expires, or is replaced. Suppose you need to cancel a previous authorization—whether because your tax issues have been resolved or you want to appoint a new attorney, you have several options. The Franchise Tax Board accepts POA revocations online and offline as long as they include the appropriate legal authority and required information from the taxpayer.
Here are the accepted methods for revoking a California POA declaration:
After revocation, your representative can no longer access your account information, submit other documents, or act on your behalf regarding your California taxes.
Filing a California Power of Attorney form may seem straightforward, but minor errors can result in processing delays, rejections, or miscommunication with the Franchise Tax Board. Avoid the following mistakes to ensure your POA declaration is accepted without issue:
California does not accept IRS Form 2848 or earlier versions of Form FTB 3520-PIT or 3520-BE. Always download the current version from the official FTB website.
Every section must be completed thoroughly, and all required signatures must be ink-based (no electronic or stamped signatures allowed).
If an email address or mailing address is outdated or inaccurate, your attorney-in-fact may not be able to receive notices or access account information.
Be sure to clearly define the tax years or income periods covered and indicate whether you grant full or limited access to the MyFTB portal.
Avoiding these issues helps ensure your representative is authorized correctly and your legal document is processed immediately.
The California Franchise Tax Board (FTB) does not accept IRS Form 2848. Likewise, an FTB power of attorney (such as Form 3520-PIT or 3520-BE) does not authorize representation before the IRS. If you need someone to represent you at the federal level, you must file a separate Form 2848 with the IRS. Each agency requires its own POA documentation, so be sure to submit the correct form to the correct tax authority to avoid delays.
A tax professional is licensed to practice before the FTB—such as a CPA, EA, or tax attorney—while an attorney is the legal title given to the individual authorized through your attorney declaration to act on your behalf. A tax professional can also be your attorney-in-fact if formally appointed using the correct form, FTB.
A durable power of attorney (POA) does not replace the need for an FTB-specific form when handling California state tax matters. Even if valid under probate law, it won’t grant authority to act before the Franchise Tax Board. Likewise, an advance health care directive only covers medical decisions, not taxes. To authorize representation, you must file FTB 3520-PIT or FTB 3520-BE and attach the durable POA only if it helps prove your representative’s signature authority.
If the form lacks any required signatures, the FTB will reject the attorney declaration, and your representative will not be granted access to your account. All POA forms must be signed in ink and include official titles if signed on behalf of a business or estate. Always follow the official instructions for form FTB 3520-PIT or 3520-BE to ensure the document is complete and valid.
