Colorado Notice of Collection Assignment Checklist

A Colorado Notice of Collection Assignment tells you that the state has transferred your unpaid tax debt to a third-party collection agency. This is a real notice that requires your attention, and it marks a shift in how Colorado will pursue the money you owe under the Colorado Revised Statutes. The state sends this notice because earlier collection attempts through standard channels did not result in payment, and it represents a significant step in the enforcement process.

Understanding what this notice states and what typically happens next will help you stay informed and avoid complicating the situation.

What This Notice Means

A Notice of Collection Assignment means Colorado's Department of Revenue has handed your unpaid tax case to a private collection agency or other authorized collection entity to attempt recovery. The notice is telling you that you owe the state, and a third party is authorized to contact you and pursue payment on the state's behalf. This is a formal notice that the standard tax collection process has been initiated and that a new party is now involved in attempting to collect what you owe.

Once your debt has been placed with a collection agency, you must work directly with them to pay your tax debt.

Why the State Sent This Notice

Colorado sends this notice in accordance with specific timing requirements established by state law. For taxpayers who are not residents of Colorado, the state may assign outstanding debts to collection agencies when taxes are more than six months past due. For Colorado residents, the state may assign debts when taxes are more than twelve months overdue.

The state may have tried other collection methods first, such as sending demand letters, filing tax liens, or making payment arrangement offers. The notice itself represents a documented determination that assignment is the next step in the authorized collection process under state government enforcement procedures.

What Happens If You Ignore This Notice

If you do not respond to the Notice of Collection Assignment or the debt collector that contacts you, the collection company will continue attempting to reach you through the United States mail, phone, or other authorized channels. Depending on the size and nature of the debt, the state or collection agency may pursue additional legal actions. However, the specific timeline and next steps are not always detailed in advance.

Collection agency fees, up to 20 percent of the debt collected, will be added to your balance. These fees are collected in addition to your tax debt and are shown as a separate charge. The longer a debt remains unpaid and unaddressed, the more these collection costs and interest will accumulate on top of what you originally owed.

What This Notice Does Not Mean

This notice does not mean the state has taken your tax refund, issued a tax levy on your depository account, garnished your wages, or filed a lawsuit in district court against you yet. It does not mean you are under criminal prosecution or that criminal charges have been filed under penal laws. The notice informs you of a collection assignment, but it is not itself a court order or a final judgment against you. You still have opportunities to address the debt or communicate with the collector.

You are not a judgment debtor at this stage unless the state has already obtained a judgment in the county court or district court.

Understanding Debt Collection Practices and Your Rights

Colorado debt collection practices are governed by both federal and state laws that protect consumers. The Fair Debt Collection Practices Act is a federal law that regulates the actions and communications of debt collectors when collecting debts. The Colorado Fair Debt Collection Practices Act provides additional consumer protections beyond those required by federal law.

These laws prohibit harassment or abuse, as well as false or misleading representations, and require validation of debts upon request. Understanding these protections can help you recognize when a debt collector is acting appropriately or when they may be violating your rights.

The Federal Trade Commission and the Consumer Financial Protection Bureau enforce federal debt collection laws and guide consumer rights. While these agencies primarily focus on private debt collection, the principles of fair treatment also apply to state tax collection.

If a collection agency contacts you, they must follow reporting requirements and provide you with information about the debt they are attempting to collect. You have the right to request written validation of the debt within 30 days of initial contact.

Checklist: What to Do After Receiving This Notice

Step 1: Read the Notice Completely

Look through the entire notice and find the following information: the tax period or year involved, the amount owed, the name of the collection agency assigned, and the collection agency's contact information. Make sure you understand which tax debt is being collected, such as state income tax, sales tax, or use tax. Copy the notice or keep it in a safe place where you can refer back to it.

Step 2: Verify the Debt Is Actually Yours

Check your records to see if you recognize the tax year, type of tax, and amount mentioned. If you filed a return for that year, look for your copy. If you are not sure the debt is correct, make a note of your questions.

Write down any specific details you remember about that tax year or filing. Do not assume the notice is wrong, but do not assume it is right either if you are genuinely uncertain. This verification step helps you determine whether the original creditor, which is the Colorado Department of Revenue, correctly assessed the debt.

Step 3: Gather Your Tax Records

Find any documents related to the year mentioned: your tax return, W-2s, 1099s, receipts, business records, or filing confirmations from the state. If you worked with a tax professional, locate their files or contact them to request copies. If you cannot find original records, write down what you remember about income, deductions, or other relevant details.

The more information you have, the better you can understand or address the debt. Keep all records organized in case legal actions require you to present them as evidence.

Step 4: Check Your Account with Colorado Department of Revenue

(Optional but Helpful)

You can create an account or log in at the Department of Revenue website to view your tax account status. This is not required, but it may show you what the state says you owe. Write down any information you find.

If the website information differs from the notice, make a note of the difference. If you are unable to access the online system, you can proceed without completing this step.

Step 5: Contact the Collection Agency

The notice will list the collection agency's phone number and mailing address. Call or write to introduce yourself and acknowledge receipt of the notice. Ask the collection agency to send you written documentation of what you owe, including the original tax debt, interest, penalties, and any collection costs already added.

Request that they explain what the debt is for, including which year, which type of tax, and what you allegedly owed. Do not agree to anything or commit to a payment amount yet; simply gather information. Be aware that collection agency fees will be added to your total balance at a rate up to 20 percent of the amount collected under Colorado Revised Statute provisions.

Step 6: Ask the Collection Agency About Your Options

Once you have made contact with the collector, ask about the options available to you: Can you set up a payment plan? Could you request a delay while you gather the necessary information? What documentation do they need from you? Write down their answers and keep detailed notes of all communications.

Different agencies may have other options, but many collectors are authorized to work with taxpayers who are trying to resolve the situation. Ask about any deadlines you need to know about, and whether they will continue debt collection practices while you gather information.

Step 7: Decide Whether to Contact the Department of Revenue Directly

The state's Department of Revenue still maintains records of your case even though collection has been assigned. You may contact the Department of Revenue directly instead of or in addition to contacting the collector. The Department can answer questions about why the debt exists or what the original assessment was based on.

The Department of Revenue's contact information should be included on your original notice or available on the state government's website. There is no requirement to contact both, but some taxpayers find it helpful to speak with the original creditor.

Step 8: Document All Contacts

Keep a written record of every phone call and letter you send or receive from the debt collector or collection agency. Write down the date, the person's name if you got one, what was discussed, and any commitments or next steps. Save copies of all letters, emails, and official documents. This record protects you and helps you track progress.

If you cannot write everything down during a call, follow up with a brief email or letter that summarizes the key points discussed and asks the other party to confirm.

Step 9: Respond to Any Follow-Up Requests

If the collection agency or the Department of Revenue sends you forms to fill out, additional documents to provide, or requests for information, respond within the timeframe given. Even if you are not sure of an answer, provide what you know and explain what you do not know. Responding shows you are engaged, and it moves the process forward.

Ignoring requests does not improve your situation and may lead to the collection agency pursuing legal actions, such as filing for a judgment in the county or district court.

Step 10: Keep Records Safe and Organized

Create a folder, whether paper or digital, with the original notice, all correspondence, your records, notes of phone calls, and any other documents related to this debt. Store it in a location where you can easily find it. Do not discard any official records.

You may need these records later if questions arise about what happened or what was agreed upon, particularly if the matter proceeds to legal action.

Common Mistakes to Avoid

● Failing to read the notice or mail from the collection agency can result in increased penalties and enforcement actions.
● Not keeping any written record of phone calls or conversations with the collector makes it challenging to track what was discussed or agreed upon.
● Providing payment to the collector without obtaining written confirmation of the payment's purpose and intended application can create confusion regarding your account balance.
● Agreeing to a payment plan you cannot afford because you are panicked or rushed will only create future problems when you are unable to make the payments.
● Assuming the collection agency is wrong without checking your own records first prevents you from understanding the actual situation.

Frequently Asked Questions

Does this notice mean I will be sued?

A Notice of Collection Assignment is not a lawsuit, but it may lead to further enforcement if the debt remains unpaid. Whether the state or the collector pursues legal actions in the district court or county court is a separate decision. No lawsuit has been filed just because you received this notice.

Will this notice hurt my credit score?

The specific credit reporting practices for Colorado tax debts assigned to collection agencies are not detailed in state laws or official Department of Revenue guidance. Contact the collection agency directly to inquire about their reporting requirements and policies.

Do I have to pay the collection agency's fees in addition to the original tax?

Yes. Collection agency fees, up to 20 percent of the debt collected, will be added to your balance. These fees are collected in addition to your tax debt and are shown as a separate charge. The costs are mandatory when a collection agency is involved, as per the provisions of Colorado Revised Statutes. The notice from the collector should itemize the portion that includes the original tax, interest, penalties, and collection costs. Request a full accounting if one is not provided.

What if I cannot afford to pay right now?

Tell the collection agency about your financial situation. Many collectors have the authority to work out payment plans or arrange delays. Being honest about your circumstances is better than ignoring the notice, and it may open up options you would not have otherwise. Consumer protections under both federal and state laws require collectors to work reasonably with taxpayers attempting to resolve their debts.
