What is a California FTB Power of Attorney?#

A California FTB Power of Attorney (POA) is a legal document that grants a representative (also called an "attorney-in-fact") the authority to interact with the FTB on behalf of the taxpayer. This includes actions like:

• Communicating with FTB agents about your account
• Receiving and reviewing your confidential tax information
• Representing you in all FTB matters
• Requesting information the FTB receives from the IRS
• Making payments or setting up payment plans

The POA defines the scope of the representative's authority (e.g., which tax years or types of taxes they can handle) and its duration (how long the representative can act on your behalf). It is governed by California state law and must comply with FTB requirements to be valid.

POA vs. Tax Information Authorization (TIA): If a representative only needs to review your tax information (for example, a new tax preparer reviewing your history), a Tax Information Authorization (TIA) may be sufficient. A POA is required for active representation in audits, disputes, or other matters where the representative needs to act on your behalf.

When Do You Need an FTB Power of Attorney?#

You may need to file an FTB POA in the following scenarios:

• Incapacity or Absence: If you're unable to manage your taxes due to illness, disability, or extended travel.
• Working with a Tax Professional: If you hire a CPA, enrolled agent, or tax attorney to handle your California state taxes (e.g., filing returns, resolving audits).
• Business Owners: If you run a business (LLC, corporation, partnership) and want to delegate tax responsibilities to a manager, accountant, or legal representative.
• Estate Planning: If you want to ensure a trusted individual can manage your taxes if you become incapacitated.
• Tax Disputes: If you need a representative to negotiate or appeal on your behalf with the FTB.

Types of FTB Power of Attorney Forms#

The FTB uses specific forms for POAs, depending on whether you're an individual or a business. The two primary forms are:

1. FTB 3520-PIT: Individual or Fiduciary Power of Attorney Declaration#

• Use Case: For individual taxpayers (including sole proprietors), estates, and trusts to appoint a representative for personal income tax matters.
• Covers: Personal income tax (Form 540, 540NR), as well as related taxes (e.g., capital gains, rental income).
• Important: If you file a joint tax return, each spouse or Registered Domestic Partner (RDP) must complete their own separate POA declaration.

2. FTB 3520-BE: Business Entity or Group Nonresident Power of Attorney Declaration#

• Use Case: For business entities, including corporations (Form 100), LLCs (Form 568), partnerships (Form 565), and estates/trusts (Form 541).
• Covers: Business tax returns and other business-related tax matters.
• Important: If your business needs representation for both its regular business return and a group nonresident return (Form 540NR), you must file two separate POA declarations.

Note: The FTB does not accept generic POA forms (e.g., those used for real estate or financial matters). You must use FTB-specific forms to ensure validity. The FTB will also reject the older form FTB 3520-C1 and non-FTB POA forms.

Step-by-Step Guide to Filing an FTB Power of Attorney#

Step 1: Determine the Correct Form#

First, confirm whether you need FTB 3520-PIT (individuals, estates, or trusts) or FTB 3520-BE (businesses). You can download the current forms directly from the FTB website:

• FTB 3520-PIT (Individuals)
• FTB 3520-BE (Businesses)

Step 2: Gather Required Information#

Before completing the form, collect the following details:

• Taxpayer Information:
  • Full legal name (must match FTB records exactly)
  • Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) (for individuals)
  • California Corporation Number (CCN), Employer Identification Number (EIN), or FEIN (for businesses)
  • Mailing address and contact information
• Representative Information:
  • Full legal name of the representative (must be an individual, not a firm or company)
  • Representative's address, phone number, and email address
  • Professional credentials (e.g., California CPA license number, California State Bar number, CTEC number, Enrolled Agent number, or PTIN) if applicable
• Scope of Authority:
  • Specific tax years or periods the representative can handle (e.g., "2022–2025" or "all years")
  • Types of actions the representative is authorized to take

Step 3: Complete the Form Accurately#

Fill out the form legibly (or type it) to avoid delays. Key sections to focus on:

For FTB 3520-PIT (Individuals):#

• Part I – Taxpayer Information: Enter your name, SSN/ITIN, address, and contact details. Check only one box (Individual or Fiduciary).
• Part II – Representative(s): List the representative's name, address, phone number, email, and credentials. A primary representative must be listed.
• Part III – Authorization Scope: Check "Yes" or "No" for all years and/or specific years. Do not use vague language like "all taxes"—this will cause rejection.
• Part IV – Additional Authorizations: Indicate whether the representative can add other representatives, sign tax returns (only in cases of incapacitation or continuous absence from the U.S. for 60+ days), receive refund checks, waive statutes of limitations, or execute settlement agreements.
• Part V – MyFTB Online Access: Choose whether to grant your tax professional full or limited online account access.

For FTB 3520-BE (Businesses):#

• Part I – Business Information: Enter the business name, CCN/EIN, address, and contact details. Check the appropriate entity type.
• Part II – Representative(s): Same as above, including the representative's credentials.
• Part III – Authorization Scope: Specify tax years or income periods and authorized actions.
• Part IV – Additional Authorizations: Similar options as the individual form.
• Part V – MyFTB Online Access: Choose the access level for your tax professional.

Step 4: Sign and Date the Form#

• Taxpayer Signature: You (the taxpayer) must sign and date the form with an original "wet" signature. The FTB does not accept electronic or stamped signatures.
• Business Signatures: If filing for a business, an authorized officer (e.g., CEO, president, CFO, vice president) must sign and include their title.
• Signing on Behalf of Someone Else: If you are signing on behalf of an individual or business using a general/durable POA, you must attach the supporting document and sign in one of the following formats:
  • For individuals: "John Doe, Attorney-in-Fact for Jane Doe"
  • For businesses: "Jane Doe, CEO, by John Doe, Attorney-in-Fact, XYZ Corp"

Step 5: Submit the Form to the FTB#

You can submit the POA online or by mail:

• Online (Recommended): Submit through MyFTB for faster processing. In the services menu, select File a Power of Attorney. This is the preferred method.
• Mail: Send the completed, signed form to the POA/TIA Unit:
  • FTB 3520-PIT and FTB 3520-BE: Franchise Tax Board, PO Box 2828, Rancho Cordova, CA 95741-2828
  • Mail the POA separately from tax returns or other correspondence to avoid processing delays.

Verify the latest address on the FTB POA page to avoid delays.

Step 6: Confirm Receipt#

After submission, wait approximately 3 weeks for the FTB to review and process the POA. If additional information is needed, it may take longer. The FTB will send a letter to the taxpayer when the POA is approved or denied. You can also check the status by contacting the FTB at 800-852-5711 or via MyFTB. Keep a copy of the signed POA for your records.

How to Revoke or Update an FTB Power of Attorney#

If you need to revoke or update your POA, you have several options:

• Online via MyFTB: This is the fastest method. Log in to MyFTB and revoke the POA relationship. Note: Online revocation is not available for fiduciaries or 540NR group nonresident return filers.
• File Form FTB 3520-RVK: Use the Power of Attorney Declaration Revocation form to revoke an existing POA before it expires.
• Call the FTB: Contact 800-852-5711 (within the U.S.) or 916-845-6500 (outside the U.S.) to revoke a POA.
• Submit a Written Statement: Mail a signed and dated letter to the FTB requesting revocation, including your name, SSN/CCN, and the representative's name.

Important Notes:

• Filing a new POA does not automatically revoke previous POAs with overlapping authorizations. You must explicitly revoke old POAs or they will remain in effect.
• If a POA was filed on or before January 1, 2018, it expired on December 31, 2023. You must file a new POA to continue the relationship.

Common Mistakes to Avoid#

To ensure your POA is processed quickly and correctly, avoid these errors:

• Incomplete Forms: Missing fields (e.g., taxpayer SSN, representative address) will delay processing or cause rejection.
• Incorrect Representative Credentials: If your representative is a tax professional, include their license/EA number to verify their authority.
• Vague Scope of Authority: Using general references like "all years" or "all taxes" will cause the form to be rejected. Be specific about tax years and types.
• Missing Signatures: The taxpayer (or authorized business officer) must sign the form with an original signature. Electronic or stamped signatures are not accepted.
• Sending to the Wrong Address: Both FTB 3520-PIT and FTB 3520-BE go to the same mailing address (PO Box 2828, Rancho Cordova, CA 95741-2828).
• Not Revoking Old POAs: If you're replacing a previous POA, explicitly revoke the old one to avoid confusion.
• Joint Filer Error: Both spouses must file separate POA forms for a joint return—one form does not cover both spouses.
• Naming a Firm Instead of an Individual: You must name an individual person as your representative, not a company or firm.

Frequently Asked Questions (FAQs)#

Q: How long is an FTB Power of Attorney valid?#

A: The POA remains valid for 6 years from the date signed, or until the end date specified in the form, or until you revoke it. To extend the POA for an additional 6 years, you must submit a new POA.

Q: Can I revoke an FTB POA?#

A: Yes. You can revoke a POA at any time using one of these methods:

• Online via MyFTB (fastest method)
• File Form FTB 3520-RVK
• Call the FTB at 800-852-5711
• Mail a signed and dated written request to the FTB

Q: Can I appoint multiple representatives?#

A: Yes. You can list multiple representatives on the form. All representatives listed have the ability to remove another representative from the POA declaration.

Q: Do I need to file a new POA if my representative changes?#

A: Yes. If your representative (e.g., your CPA) leaves or is replaced, file a new POA with the new representative's information and revoke the old one.

Q: Is there a fee to file an FTB POA?#

A: No. Filing an FTB Power of Attorney is free.

Q: Can my representative sign my tax return?#

A: Only in very specific circumstances. Your representative can sign your tax return only if you are incapacitated due to illness/injury or continuously absent from the United States (including Puerto Rico) for at least 60 days before the filing deadline.

Q: What is the difference between limited and full online access for my tax professional?#

A: Limited access allows your tax professional to view notices and correspondence issued within the last 12 months. Full access allows them to view estimated tax payments, account summary information, and take actions on your behalf through MyFTB for the authorized tax years.
