Legal Requirements for Using the Tax Power of Attorney Form in the State of Washington

Taxpayers in Washington may authorize a representative when dealing with complex or sensitive matters involving the Department of Revenue. This includes audits, disputes, payment arrangements, and reviewing confidential tax records. Authorizing someone else helps when taxpayers cannot manage their affairs due to absence, illness, or legal complexity. Delegating authority ensures timely communication with DOR officials and protects taxpayers' interests.

Washington requires the use of its tax power of attorney, known officially as Form 42-2446. This state-specific document grants limited authority for handling matters with the Washington Department of Revenue only. Taxpayers must complete this form accurately to ensure the state recognizes the representative's legal standing. Other forms, including federal documents, are not accepted for state-level tax matters.

Form 42-2446 is separate from the IRS’s federal Form 2848, which is used for national tax representation. Filing the federal POA with the IRS does not authorize communication with the Washington Department of Revenue. Taxpayers must file both forms if they need representation at both the federal and state levels. Using the correct form prevents delays, confusion, and potential noncompliance with state tax procedures.

Legal Function and Scope of a Tax Power of Attorney Form in the State of Washington

In Washington, the tax power of attorney form is critical in authorizing another person or representative to act on a taxpayer’s behalf in specific dealings with the Washington State Department of Revenue. Below is a breakdown of its legal function, limits, and how it differs from federal authorizations.

• Legal Authority Granted to a Representative: The tax power of attorney form in the state of Washington—officially titled Form 42-2446—allows a taxpayer (individual or business) to authorize a person or multiple representatives to act on their behalf when communicating with the Department of Revenue. This includes access to confidential tax information, representation in revenue taxpayer account administration matters, and handling specific tax issues like filing, payments, or audits.
• Representation is Specific to Washington State Tax Matters: This attorney form only applies to Washington tax matters and does not grant authority for federal issues. For example, a power of attorney form used with the IRS (such as Form 2848) is separate. Washington’s power of attorney must be submitted to the state’s Department of Revenue as a standalone form and is limited to state-level representation.
  
  
• Limitations on What the Representative Can and Cannot Do: While the power of attorney allows access to confidential tax information, it does not allow the representative to sign tax returns, enter into binding settlement agreements, or make legal decisions outside the scope defined by the form. Additional legal documents must be filed and validated for broader representation, including estate, trust, or legal proceedings.
  
  
• Required Format and Submission Process: The Washington tax power of attorney form must be appropriately completed and submitted as a PDF, by fax, mail, or secure electronic delivery. Taxpayers must ensure the form includes all required identification and contact information for the taxpayer and their representative. Incomplete or incorrectly formatted documents may delay processing or result in denial.

A tax power of attorney in Washington is a legally binding document providing targeted authority within the state tax law's boundaries. While it enables proper representation for routine tax matters, it is deliberately limited in scope to protect the taxpayer and confidential tax information.

Legal Recognition of the Confidential Tax Information Authorization (Form 42-2446)

In Washington, the Confidential Tax Information Authorization—Form 42-2446—is the officially recognized tax power of attorney form used by the Washington State Department of Revenue. It plays a central role in allowing individuals and businesses to authorize a representative to access confidential tax information and communicate with the department on their behalf. Below is a clear breakdown of how this form functions under state law and how it compares with similar documents in other states.

Washington’s Official Tax Authorization Form

Form 42-2446 is the only power of attorney form accepted by the Washington State Department of Revenue for tax-related matters.

• This form is required when a taxpayer wishes to authorize another person—such as an attorney, CPA, or tax professional—to access their revenue taxpayer account administration information.
  
  
• It applies to individual and business representation, allowing third-party access to confidential tax files.
  
  
• The form does not allow a representative to sign tax returns or make binding legal decisions; it is limited strictly to information access and communication with the Department.

Function Under State Privacy and Disclosure Laws

Washington law requires written, specific authorization before releasing taxpayer information—Form 42-2446 fulfills that legal standard.

• Under RCW 82.32.330, the Department of Revenue prohibits disclosing confidential tax information without proper authorization.
  
  
• By filing this tax power of attorney form in Washington, taxpayers ensure compliance with state privacy laws while enabling representation.
  
  
• The form protects taxpayer data by limiting the scope of access to what is granted in writing. It does not provide blanket authorization.

How It Differs From Other States’ Power of Attorney Forms

Unlike many states that accept the IRS Form 2848 or other generic attorney forms, Washington requires a specific state-issued form.

• Washington’s Form 42-2446 must be submitted directly to the Department—via mail, secure fax, or uploaded PDF—and it is not interchangeable with federal or out-of-state documents.
  
  
• Some states allow broader powers (such as filing or signing tax documents); Washington’s tax power of attorney is intentionally limited to safeguard confidential information.
  
  
• For multi-state tax issues, separate POAs may be required in each state, as Washington’s form is not valid for federal IRS use or in other jurisdictions.

The Washington tax power of attorney form (Form 42-2446) is a vital, narrowly scoped document that ensures legal access to taxpayers' confidential records while preserving strict privacy protections under state law. Whether you're a business owner, an individual taxpayer, or a professional representative, understanding this form's limits and state-specific requirements is key to compliant and effective representation.

What the Attorney Form Legally Allows and Prohibits

In the State of Washington, the Tax Power of Attorney (Form 42-2446) provides a clearly defined legal scope for authorizing a representative to access and discuss a taxpayer's confidential tax information with the Washington Department of Revenue (DOR). However, it is not a blanket delegation of legal authority. Here's what the form allows, prohibits, and when additional documentation is legally required:

Access to Confidential Tax Records and DOR Communications

What it allows:
Form 42-2446 authorizes the named representative to:

• Receive, inspect, and discuss confidential Washington state tax records.
  
  
• Communicate directly with the DOR on behalf of the taxpayer regarding matters listed on the form (such as business excise tax or sales/use tax).
  
  
• Receive copies of notices and correspondence from the DOR related to the specified tax matters and periods.

This access is granted under Washington state confidentiality statutes (e.g., RCW 82.32.330) and requires proper completion of the form to be legally recognized.

No Authority to Sign or Bind on Behalf of the Taxpayer

What it does NOT allow:
Form 42-2446 does not:

• Authorize the representative to sign tax returns.
  
  
• Permit the representative to enter into binding agreements or settlements with the DOR.
  
  
• Allow representation in formal hearings such as those before the Board of Tax Appeals (unless additional forms are submitted).
  
  
• Authorize broad legal powers, such as handling matters outside the tax scope or engaging in legal negotiations.

The representative’s authority is limited strictly to the tax matters and years indicated on the form.

Legal Representation in Hearings or Complex Cases Requires Additional Documents

When you need more than just Form 42-2446:

• Board of Tax Appeals Hearings: To appear before the BTA, an attorney must typically be licensed to practice in Washington, and additional documentation may be required to establish legal representation rights.
  
  
• Estate, Trust, or Guardianship Matters: Fiduciaries must submit supporting legal documents (e.g., letters testamentary or court appointments) to validate authority.
  
  
• Multi-party or Out-of-State Authorizations: If more than one party is being represented, or if the representative is located out of state, supplemental authorizations such as a General Durable Power of Attorney or notarized declarations may be required.

While Form 42-2446 is essential for granting access to your Washington state tax records and engaging with the DOR, it is a narrow authorization, not a substitute for broader legal authority. Understanding its limits ensures compliance and prevents miscommunications during your tax matter resolution.

Privacy Protections and the Legal Role of Confidential Tax Information

In Washington State, protecting taxpayer privacy is not just a best practice—it’s mandated by law. The Department of Revenue (DOR) enforces strict confidentiality rules under RCW 82.32.330, which limits how and when taxpayer information can be disclosed. Here’s how the legal framework and Form 42-2446 work together to safeguard sensitive tax information:

• Strict Confidentiality Under RCW 82.32.330: Washington’s Revised Code (RCW 82.32.330) prohibits the Department of Revenue from disclosing any taxpayer information—whether individual, business, or corporate—except in specific, legally permitted circumstances. This includes tax returns, audit findings, financial records, and other identifying data. Violating these provisions is considered a misdemeanor, and employees who breach this law may face criminal penalties.
  
  
• Written Consent Is a Legal Prerequisite for Disclosure: Before the DOR can release any taxpayer information to a third party, it must receive written authorization from the taxpayer. This is not optional—it’s a statutory requirement under RCW 82.32.330(3). Form 42-2446 serves as this written consent, identifying who may access the taxpayer’s information, what they may access, and for how long. Without this form (or a similarly valid written authorization), DOR staff are legally barred from discussing or sharing details—even with family members or accountants.
  
  
• Form 42-2446 Establishes Secure and Controlled Access: This form isn’t just procedural—it’s a legal boundary. Form 42-2446 allows the taxpayer to precisely define the scope of access: which accounts, tax periods, and tax types (e.g., B&O, sales tax). The DOR will only communicate with the named representative about the specified items—any attempt to exceed the defined scope results in denial of access. The form limits exposure by creating a controlled communication channel, ensuring sensitive tax data is not unintentionally or unlawfully disclosed.

Together, Washington's legal statutes and Form 42-2446 provide a robust framework to protect taxpayers from unauthorized access or misuse of their confidential tax information. Ensure this form is completed correctly and submitted before expecting third-party access to your tax records.

Requirements for Properly Completing the Power of Attorney Form

Specific legal, identification, and documentation requirements must be met to correctly complete the Washington State Department of Revenue’s Power of Attorney form (Form 42-2446). Here's a clear breakdown of what taxpayers and their representatives need to know:

Authorized Signatories: Who Can Legally Sign the Form

• The taxpayer or an individual with legal authority over the taxpayer’s affairs must sign the form.
  
  
• For individual taxpayers, this means the person whose tax matters are involved.
  
  
• For businesses, a duly authorized officer, partner, member, or manager must sign—typically someone listed in the business’s registration with the Secretary of State.
  
  
• In the case of trusts, estates, or guardianships, court-appointed fiduciaries (executors, administrators, or legal guardians) are the authorized parties.

Required Fields: Information That Must Be Included

• The form requires accurate and complete identification of the taxpayer and the appointed representative.
  
  
• Mandatory taxpayer information includes:
  
  
  • Name and mailing address
    
    
  • Unified Business Identifier (UBI) if applicable
    
    
  • Account or permit numbers associated with tax accounts
    
    
• For the representative, include:
  
  
  • Full legal name
    
    
  • Mailing address
    
    
  • Telephone number and email address
    
    
  • Type of representation (e.g., attorney, CPA, enrolled agent)

Fiduciary Documentation: When Extra Proof Is Required

• Fiduciaries (such as legal guardians, executors, or trustees) must submit supporting legal documentation verifying their authority to act on behalf of the taxpayer.
  
  
• Examples include:
  
  
  • Letters of Testamentary
    
    
  • Court orders of appointment
    
    
  • Trust agreements
• If signing on behalf of a business, a corporate resolution or internal authorization letter may be necessary if the signatory’s authority is not already recorded with the Department of Revenue.

Filling out Form 42-2446 correctly is not just administrative—it ensures legal authorization is appropriately documented and your tax matters can be handled efficiently. A single omission or misstep could delay or invalidate your representation. Be precise, be thorough, and always double-check before submission.

Submitting the Tax Power of Attorney Form in the State of Washington

Submitting the Tax Power of Attorney (Form 42-2446) in Washington is a formal legal process, and it’s essential to follow the correct procedures to ensure your representative is properly authorized to act on your behalf with the Department of Revenue (DOR). Below is a breakdown of what you need to know to submit this form properly—and make sure it’s accepted without delay.

Approved Submission Methods: Choose the Legally Recognised Channels

Washington State’s Department of Revenue accepts Form 42-2446 through three official channels only:

• Mail: Send the completed form to the DOR’s designated address. Ensure it's addressed correctly—misdirected mail can delay processing.
  
  
• Fax: Fax submissions are accepted at the number provided on the form. Always confirm that all pages transmitted are received.
  
  
• Secure Web Message or Email Portal: The DOR allows electronic submission via its My DOR online account or designated secure portals. Never send tax documents via unencrypted email.

Submission Proof Is Not Optional: Protect Your Legal Rights

Retaining documentation of your submission is more than good practice—it’s a legal safeguard.

• Mail Receipts: Use certified mail with tracking to establish the date the DOR received your form.
  
  
• Fax Confirmation: Always save the fax transmission report, as it serves as a legal timestamp.
  
  
• Digital Timestamp: Download or screenshot the confirmation page or acknowledgment email from My DOR for electronic submissions.

Direct Coordination with DOR Employees: Know When and How

If a specific Washington State DOR employee assists with your matter, extra steps are taken to ensure the form is routed correctly.

• Include Employee Name or ID: When instructed, write the employee’s name or ID number on the form to direct it internally.
  
  
• Confirm with the Employee: Verify if additional identifying details or reference numbers should be included to avoid misrouting.
  
  
• Use Direct Communication Channels: Some cases—such as audits or payment disputes—may allow or require direct email or document uploads to the employee’s case file system.

Accurate submission of Form 42-2446 isn’t just about filling in the blanks—it’s about sending it through the right channel, retaining proof, and coordinating where needed. These steps ensure your representative can act without unnecessary delays or legal disputes.

Situations That Require Additional Power of Attorney Documentation

Certain legal and administrative scenarios in Washington State require more than just the standard Form 42-2446 to authorize tax representation fully. Below are specific situations where additional power of attorney documentation is necessary to meet legal, procedural, or jurisdictional obligations.

Board of Tax Appeals Hearings Require Legal Standing

Form 42-2446 allows a representative to access tax information and communicate with the Department of Revenue (DOR). Still, it does not grant the authority to act as legal counsel in formal adjudicative settings.
In appeals before the Washington State Board of Tax Appeals, a taxpayer must either:

• Represent themselves (pro se),
  
  
• Be represented by a licensed attorney, or
  
  
• File an additional legal power of attorney (often general or durable) naming the attorney or agent with appropriate legal authority under Washington State law.

Estate, Trust, and Guardianship Matters Require Fiduciary Documentation

When dealing with a deceased taxpayer, a minor, or an incapacitated person, Form 42-2446 alone is not enough. The DOR requires documentation verifying the legal capacity of the representative.
This includes:

• A court-issued Letter of Testamentary (for executors),
  
  
• A Letter of Guardianship (for guardians),
  
  
• Or a Trust Agreement (for trustees).
  These documents must accompany the POA form to validate the fiduciary’s authority to access or act on tax matters.

Multi-Party or Out-of-State Authorizations Require Expanded Clarity

If the taxpayer is based outside of Washington, is represented by multiple agents, or is part of a joint business entity, supplementary documentation is essential to clarify scope, jurisdiction, and consent.
Examples include:

• Separate POA forms are available for each individual if more than one party is authorized.
  
  
• A business resolution naming an authorized signatory,
  
  
• Or a reciprocal legal document validating the representative’s authority across state lines.
  This is particularly important in cases involving multi-state taxation or foreign LLCs doing business in Washington.

In summary, while Form 42-2446 is Washington's primary tool for tax-related authorization, it is not a one-size-fits-all solution. In complex or formal situations, additional legal documentation is required to establish authority, protect taxpayer rights, and comply with state law.

FAQs

Is the Washington form valid for IRS matters?

Washington State’s Form 42-2446 invalidates for IRS or federal tax matters. It is strictly used to authorize someone to access confidential tax information or communicate with the Washington Department of Revenue (DOR). If you need to authorize representation before the IRS, you must complete Form 2848, the federal Power of Attorney form, which operates under different legal authority and privacy regulations.

How long is the authorization legally valid?

The authorization provided by Form 42-2446 remains valid until the expiration date listed on the form or until the taxpayer revokes it in writing. If no expiration date is specified, the form stays in effect indefinitely. However, the Department of Revenue recommends setting a precise end date or reviewing authorizations periodically to ensure they remain current and appropriate for the taxpayer's ongoing needs and circumstances.

Can I submit more than one power of attorney form?

You may submit multiple Power of Attorney forms to the Washington Department of Revenue. Each form can authorize a different representative or apply to other tax matters or periods. However, be aware that submitting a new form may revoke prior authorizations unless specified otherwise in the latest submission. Taxpayers should indicate if they wish to retain existing representatives when filing additional forms.

Do I need to be a Washington resident to use the form?

No, you need not be a Washington resident to use Form 42-2446. Anyone with Washington tax obligations—such as businesses, out-of-state sellers, or individuals with Washington-based tax interests—can use the form to authorize a representative. The form applies to any taxpayer dealing with the Washington Department of Revenue, regardless of physical residency or location, as long as it relates to state tax matters.

What legal authority is required for fiduciaries to use this form?

Fiduciaries—guardians, trustees, or executors—must submit supporting legal documentation with Form 42-2446 to verify their authority. This may include court orders, letters of guardianship, trust instruments, or other documents showing legal capacity to act on behalf of the taxpayer. The Department of Revenue requires this proof to ensure the fiduciary is lawfully empowered to access or manage confidential tax information under state law.
