What Form CDTFA-392 (2025) Is For
Form CDTFA-392 (2025) is a power of attorney form that allows a taxpayer to authorize a representative to communicate with the California Department of Tax and Fee Administration (CDTFA). It permits the representative to discuss taxes, account records, payments, and compliance matters related to programs such as sales and use tax.
This form does not file a tax return or change tax liability. Instead, it allows CDTFA to share confidential account information with an authorized agent and recognize that person’s actions within the scope granted.
When You’d Use Form CDTFA-392
A taxpayer would use Form CDTFA-392 when help is needed to manage CDTFA communications, respond to notices, or address an audit or collection issue. It is commonly used by businesses and individuals working with a CPA, attorney, or other qualified representative.
The form may be filed at any time, including after CDTFA has contacted the taxpayer or when correcting past-due matters. It is also used when changing representatives or revoking a prior power of attorney.
Key Rules or Details for 2025
Form CDTFA-392 must clearly identify the tax programs and time periods the representative is authorized to handle. Accurate taxpayer and representative information is required so CDTFA can verify authority and protect confidential records.
The 2025 designation reflects the current form version and does not affect filing deadlines or tax calculations. Rules related to income tax benefits or credits do not apply, as this form only governs representation before CDTFA.
Step-by-Step (High Level)
Step 1. Confirm what authority is needed
A taxpayer should determine whether the representative requires broad or limited authority for specific actions, periods, or accounts. This should align with what the representative is expected to do during an audit, correspondence cycle, or dispute resolution.
Step 2. Gather the information needed to complete the form
A taxpayer should gather information that matches CDTFA account records and confirms the representative’s identity.
A taxpayer should gather the following:
- CDTFA account or permit numbers are tied to taxes and payments.
- The taxpayer's identifying information is required for the account, which may include their Social Security details.
- Provide the representative’s name, contact information, and identifier information.
- Identify the specific periods and programs involved, including the sales and use tax periods that are associated with the tax returns.
Step 3. Complete the taxpayer and representative sections accurately
A taxpayer should enter their legal name as registered with the CDTFA and confirm that their contact information is up to date. A taxpayer should list the representative as a person, even when the representative works for a business.
Step 4. Specify programs, periods, and powers
A taxpayer should identify the CDTFA program involved and clearly list the covered periods. A taxpayer should also ensure the powers granted match the intended actions, including communications, document submissions, and audit-related steps.
Step 5. Sign, submit, and keep copies
A taxpayer should confirm that the correct person signs the form based on the taxpayer entity type. A taxpayer should maintain both digital and paper copies, including any confirmation pages from the CDTFA website.
Common Mistakes and How to Avoid Them
Listing a firm instead of a person
A taxpayer should list an individual representative by name rather than only a business name. This helps avoid processing delays and confusion about who is authorized to act on behalf of the organization.
Using vague periods or unclear program coverage
A taxpayer should list time periods clearly and select the correct CDTFA program. Vague terms like “recent years” can delay access or limit the representative’s ability to discuss the proper records.
Using the wrong signer for a business
A taxpayer should verify that the signer has the authority to act on behalf of the business. A taxpayer should be prudent when officers or ownership have recently changed, because CDTFA may question the signing authority.
Confusing CDTFA-392 with medical or estate documents
A taxpayer should not confuse this form with a health care power of attorney, a medical power of attorney, an advance directive, a living will, or a HIPAA authorization. Those documents address medical care, protected health information, and medical records, not CDTFA tax matters.
Forgetting to revoke old authorizations
A taxpayer should clearly document the revocation of the power of attorney when switching representatives. Explicit revocation reduces the likelihood that the CDTFA will continue sending records to a prior representative.
What Happens After You File
After the CDTFA processes the form, the representative can generally communicate with the CDTFA about the covered taxes, payments, and records within the specified periods and programs. The taxpayer should still monitor deadlines and correspondence, as they remain responsible for compliance even when a representative is involved.
If the taxpayer later needs to revoke the authorization, they can do so through updated documentation that clearly identifies the representative and states the revocation. If the taxpayer is incapacitated or if authority is handled through a guardian, conservator, trustee, or executor, supporting court documentation may be required, depending on the specific facts.
