Colorado Notice of Collection Assignment Checklist

If you receive a Colorado Notice of Collection Assignment, it means the Colorado Department of Revenue has transferred your unpaid tax balance to its collections unit for enforcement. While this notice may seem alarming, it is essential to understand what the state can and cannot do under Colorado State Law. In particular, unpaid taxes no longer affect your driver's license or driving privileges.

This checklist explains how tax collection works in Colorado, outlines the enforcement actions permitted, and provides guidance on steps to protect yourself from escalating penalties and interest.

What Colorado Cannot Do for Unpaid Taxes

Colorado’s authority to collect unpaid taxes changed significantly in 2021. Under Colorado Revised Statutes, the Colorado Department of Revenue no longer has the power to suspend or revoke a driver’s license or driving privilege based solely on unpaid tax debt. Previously, license suspension was sometimes used as a collection tool; however, this practice is now prohibited.

The Department of Revenue cannot involve the Division of Motor Vehicles, the Department of Motor Vehicles, or the Colorado Department of Motor Vehicles to take action against a Colorado driver’s license for unpaid taxes. A Colorado Notice of Collection Assignment does not trigger a license suspension, license revocation, Notice of Revocation, or Order of Revocation. These actions are reserved for traffic violations, specific court orders, or other non-tax-related matters.

Tax debt also does not result in a Colorado DMV hearing or any other type of DMV hearing. There is no hearing process, administrative hearing officer, or hearing transcript associated with tax collection. If you receive a letter suggesting your driving privileges are at risk because of unpaid taxes, verify the notice directly with the Colorado Department of Revenue, as that type of enforcement is not authorized by law.

What Colorado Can Do for Unpaid Taxes

Although license-related penalties are no longer permitted, the Colorado Department of Revenue still has several enforcement tools available under Colorado State Law. A Colorado Notice of Collection Assignment signals that these tools may be used if the debt remains unresolved.

One common action is the filing of a tax lien against your property. A lien becomes part of the public record and can affect your credit and ability to sell or refinance property. The Department of Revenue typically provides notice before filing a lien, allowing you to respond.

The state may also levy bank accounts or garnish wages. These actions do not require a criminal case, involvement in a criminal court, or review by the Colorado Judicial Branch. In certain situations, the Department of Revenue may file documents with a district court to enforce collection; however, this process remains civil in nature and does not involve traffic enforcement or the Department of Motor Vehicles.

Interest and penalties continue to accrue on unpaid taxes, which can significantly increase the total balance owed over time. Addressing a Colorado Notice of Collection Assignment early can help limit these added costs.

Common Reasons You Might Owe State Taxes

Many Colorado taxpayers owe state taxes because they filed a return but were unable to pay the full amount due. Others discover a balance after the Department of Revenue reviews a return and corrects reported income, deductions, or credits.

Business owners may owe unpaid sales tax, withholding tax, or other state taxes. In some cases, an audit conducted under Colorado State Law results in additional tax liability. These tax obligations are unrelated to traffic tickets, traffic violation points, unpaid tickets, or any issues involving a suspended license.

Checklist: What to Do If You Owe Colorado State Taxes

Step 1: Verify the Debt and Review All Notices

Contact the Colorado Department of Revenue to confirm the amount listed in your Colorado Notice of Collection Assignment. Request a detailed breakdown that includes the original tax, penalties, and interest. Review each notice carefully to ensure the balance is accurate and tied to the correct tax periods.

Be cautious not to confuse tax notices with a revocation letter or other license-related correspondence. Tax collection notices do not affect your driver's license or driving privileges.

Step 2: Gather Your Tax Records and Payment Documentation

Collect copies of filed tax returns, payment confirmations, and correspondence from the Colorado Department of Revenue. Compare your records with the state’s assessment to identify any discrepancies.

If you believe an error exists, document it clearly and accurately. Accurate records are essential if you plan to dispute the balance or request adjustments under Colorado State Law.

Step 3: Understand Your Payment Options

The Department of Revenue offers payment plans for taxpayers who are unable to pay in full. These agreements allow monthly payments over time and can pause specific collection actions while you remain compliant.

Unlike Department of Motor Vehicles matters, there is no reinstatement fee, application for Reinstatement, or Reinstatement Requirements associated with tax debt. You will not be asked to provide evidence of insurance, current liability insurance, or auto insurance for tax collection purposes.

Step 4: Consider Filing a Protest

If you disagree with the assessment, Colorado Revised Statutes provide the right to file a formal protest. Deadlines are strict, often requiring action within 30 days of the notice date.

A protest may be reviewed by the Department of Revenue and, in some cases, may lead to proceedings in the district court or oversight by the Attorney General. These matters remain civil and do not involve the Department of Motor Vehicles or any license suspension process.

Step 5: Get Professional Help If Needed

Complex tax issues may benefit from professional assistance. A qualified tax professional can help explain your options, communicate with the Department of Revenue, and ensure your rights are protected. Establishing a clear attorney-client relationship or professional advisory relationship can be especially helpful when large balances or audits are involved.

Step 6: Communicate with the State Promptly

Do not ignore a Colorado Notice of Collection Assignment. Respond within stated deadlines and keep records of all communications with the Colorado Department of Revenue. Prompt communication often leads to more manageable outcomes and prevents unnecessary escalation.

Step 7: Make Payments as Agreed

If you enter a payment plan, ensure that you make each payment on time. Missing payments can result in renewed collection actions such as liens or garnishments. Monitor your account to confirm that payments are credited adequately in accordance with Colorado State Law.

Common Mistakes to Avoid

A common mistake is assuming unpaid taxes can lead to a suspended driver’s license or revoked license. This is no longer permitted in the state of Colorado. Another mistake is ignoring notices, which allows penalties and interest to grow.

Do not assume you must attend a DMV hearing or resolve tax debt through the Colorado DMV. Tax collection is handled entirely by the Department of Revenue and does not involve license suspension or procedures with the Department of Motor Vehicles.
