What the Colorado Tax Information Authorization Is

The Colorado Tax Information Authorization is a written form that allows a taxpayer to authorize disclosure of state or federal tax records to a designated third party. It identifies the taxpayer, the recipient(s) of tax data, the scope of information to be shared, and the effective period. The form is used for representation, tax preparation, third-party verification, or release of information to lenders and legal representatives. Proper completion ensures authorized access while preserving privacy controls and auditability.

Why this authorization matters for taxpayers and agents

A clear, signed authorization lets the Colorado Department of Revenue or other tax authorities disclose return information to an authorized person, avoiding delays when a third party needs access. It documents consent, limits scope, and creates a record useful for audit, compliance, and dispute resolution.

Why this authorization matters for taxpayers and agents

Who typically completes a Colorado Tax Information Authorization

Select the role that matches your situation and ensure the signer has legal authority to grant disclosure.

  • Individual taxpayers seeking third-party help with filings or audits
  • Tax preparers or CPAs acting on behalf of clients
  • Attorneys or lenders verifying tax history for transactions

Core elements found in a professional authorization

A complete Colorado Tax Information Authorization should clearly define parties, scope, dates, and signature requirements so recipients and agencies can act without ambiguity.

Authorization Scope

Specify which tax years, forms (e.g., returns, assessments), and categories of information the designee may access; avoid open-ended language that could be misinterpreted.

Designated Recipient

Provide the recipient's legal name, business name if applicable, contact details, and a clear description of the recipient's role to ensure accurate routing and verification.

Effective Dates

Declare a clear effective start date and expiration or event-based termination to limit disclosure to the intended timeframe and reduce long-term exposure.

Taxpayer Identification

Include the taxpayer's full legal name, SSN or ITIN, current mailing address, and any prior names to match agency records precisely and prevent misidentification.

Signature Block

Require the taxpayer's handwritten or electronic signature and date, and, where applicable, the signer’s title or authority if signing for an entity or as a representative.

Limitations & Conditions

Note any restrictions on use, redisclosure, or retention of the information and state whether copies, extracts, or summaries may be made by the recipient.

    1. Identify parties: Enter the taxpayer and recipient full legal names.
  • 02
    2. Define scope: List tax years and specific documents to release.
  • 03
    3. Set dates: Use clear start and end dates in MM/DD/YYYY.

How to set up an online completion workflow

Field Configuration
Taxpayer Name Field Required; auto-validate spelling
Taxpayer ID Field Required; numeric-only mask
Scope Selector Conditional fields for years

Where the authorization goes and what happens next

Understand routing so you know which agency or recipient will receive the form and how it will be processed after signature.

  • Submit to Agency: Send to Colorado DOR or other agency listed.
  • Recipient Access: Designated recipient receives scope-limited records.
  • Agency Verification: Agency matches form to taxpayer records.
  • Record Retention: Authorized copies are retained per policy.

Digital delivery and authentication options

Choose the authentication level that matches the agency's acceptance rules and the sensitivity of the tax data; stronger methods reduce fraud risk and improve admissibility.

  • Basic Authentication: Email verification
  • Stronger Authentication: SMS code or knowledge-based
  • Audit Trail: IP, timestamp, actions

Timing considerations and related filing deadlines

Know timing that affects the authorization and associated tax filings; some reporting deadlines determine when disclosures are required or helpful.

W-9 and TIN requests:

Provide upon payer request; no set deadline

1099-NEC reporting:

Recipient and IRS deadline: Jan 31

1040 individual return:

Filing due April 15; extension to Oct 15

FBAR reporting:

Due April 15 with automatic Oct 15 extension

Agency processing:

Processing times vary by office and request load

Common mistakes to avoid when preparing the form

  • Using nicknames or abbreviated names that do not match agency records, leading to processing delays or rejection.
  • Leaving the scope vague (for example, saying 'all records') instead of listing specific years and document types.
  • Failing to include taxpayer identification number or entering it with formatting errors, which can trigger backup withholding or denials.
  • Not specifying expiration or termination conditions, which can unintentionally grant long-term access to sensitive tax data.

Potential penalties and risks from incorrect or improper authorizations

Backup Withholding: 24% withholding
Incorrect TIN: Filing penalties possible
Late Disclosure: Processing delays
Unauthorized Release: Privacy breach risk
Intentional Misuse: Civil or criminal exposure
Revocation Failure: Continued access risk

Typical signers and their roles

Individual Taxpayer

A natural-person taxpayer signs to authorize disclosure to a third party. Ensure the name and TIN match agency records and provide contact information for verification.

Authorized Representative

A CPA, attorney, or agent signs on behalf of a taxpayer only with documented authority; attach power of attorney or written consent when the representative is executing the form.

Real-world examples of common uses

These examples illustrate typical scenarios where a Colorado Tax Information Authorization is used to streamline third-party access.

Tax Preparer Request

A taxpayer engages a CPA to resolve an audit and signs an authorization permitting the CPA to obtain Colorado and federal transcripts.

  • The CPA requests transcripts directly from the agency.
  • The authorization speeds document retrieval, enables timely responses during the audit, and documents consent for future follow-up correspondence.

Mortgage Closing

A borrower signs an authorization allowing a lender to verify tax returns for underwriting of a mortgage application.

  • Lender obtains tax transcripts.
  • The authorization clarifies permitted use and expiration, preventing unintended redisclosure after loan closing.

Practical tips for accurate and efficient processing

Following these practices reduces rework and protects taxpayer privacy across the information-sharing lifecycle.

Verify identity and TIN
Confirm the taxpayer’s full legal name and SSN/ITIN against agency records before submitting. A single character mismatch can cause request rejection and delay release of records.
Limit scope and duration
Describe specific tax years, forms, and an expiry date. Narrowly tailored authorizations reduce exposure and make it easier for agencies to comply with the request.
Record revocation method
Include explicit revocation instructions and a method to notify agencies and recipients. Maintain a dated copy of any revocation to demonstrate termination of consent.
Retain signed copies securely
Store completed authorizations in encrypted records with access logs; maintain retention according to federal and state standards to support audits and legal inquiries.
