Colorado Notice of Demand for Payment Checklist
A Colorado Notice of Demand for Payment is a formal letter from the Colorado Department of Revenue, informing you that you owe unpaid state taxes and requesting payment by a specific deadline. The state sends this notice when your account shows an unpaid tax balance that has not been resolved through earlier payment requests or notices. This notice is significant because it marks a more advanced stage in the collection process.
Ignoring it can lead to additional enforcement actions, such as wage garnishment, bank levies, or property liens, which are more difficult to undo than a straightforward payment arrangement.
What This Notice Means
The Colorado Notice of Demand for Payment tells you that the state has determined you owe a specific amount in unpaid Colorado income tax or other state taxes, and the state is formally requesting payment within a deadline shown on the notice. This is not a bill you can ignore or respond to later without consequences. It means your tax account is now in the state's active collection system, and the state has given you a final opportunity to pay or make contact before pursuing more aggressive collection methods.
This Final Determination represents the conclusion of the protest process regarding an earlier notice you may have received. The notice creates a legal obligation for you to respond or pay within the specified timeframe to avoid additional penalties and enforcement actions.

Why the State Sent This Notice
Colorado sends this notice when a taxpayer has an unpaid tax balance that remains uncollected after the state's normal payment follow-up process. This typically happens when an original tax bill was issued, but payment was not received, or when a payment plan or previous notice did not result in payment.
The notice is part of the state's standard collection procedure under Colorado State tax law and does not necessarily mean the state believes the tax was miscalculated. It means the amount owed is still showing as unpaid in the state's records.
What Happens If You Ignore This Notice
If you do not respond to or pay the Notice of Demand for Payment by the deadline shown on the notice, the Colorado Department of Revenue typically moves forward with enforcement collection actions. These actions may include placing a lien on your real property (which means the state has a legal claim against your home, land, or real estate), garnishing your wages (having money taken directly from your paycheck), or levying your bank account (having money taken from your savings or checking account).
The state may also refer your debt to a third-party collection agency authorized to enforce collections on behalf of the department. Once enforcement actions begin, they are more costly and time-consuming to reverse than responding to the notice itself. The specific timeline for when the state moves to these actions is not clearly published in publicly available state guidance, so you should not assume you have unlimited time after the deadline passes.

What This Notice Does Not Mean
This notice does not mean you have already lost the ability to discuss the debt or work out a payment arrangement with the Collections Department. It does not mean the state has automatically seized your property or bank account; those actions come later if the notice deadline passes without response. It also does not automatically imply the tax amount is correct or final.
You may still have options to dispute the amount if you believe it is incorrect. However, these options typically need to be exercised promptly and separately from responding to this demand notice. Understanding your collection options helps you make informed decisions about resolving your tax problem before the situation escalates.
Checklist: What to Do After Receiving This Notice
Step 1: Read the entire notice carefully
Find and write down the following information:
● The tax year or period to which the debt applies.
● The total amount owed, including any penalties and interest.
● The payment deadline date is shown on the notice.
● The name and phone number of the contact person or office.
● Are there specific instructions on how to make a payment?
● Whether this is a Final Determination or an earlier notice stage.
Step 2: Gather your tax records for the year in question
Look for the following documents:
● Your original tax return for that year, showing your reported income.
● Any correspondence from the state about this tax debt.
● Proof of any payments you made toward the balance.
● Any documents showing you disputed this amount previously or filed a Rejection of Refund Claim.
Step 3: Verify the debt is actually yours
Check the following details to ensure accuracy:
● The tax year matches the year you filed with Colorado.
● The amount seems reasonable, given your income that year.
● The address on the notice is correct and matches your current mailing address.
● The name on the notice matches your legal name on file with the state.
If you notice errors in basic information, contact the Taxpayer Helpline immediately to address these issues before the deadline.
Step 4: Decide on your following action
You have several options available to you depending on your financial situation.
Option A: Pay the full amount by the deadline. Follow the payment instructions on the notice exactly. Keep proof of your payment, including confirmation numbers or receipts. Make note of the payment method and date for your records.
Option B: Contact the Colorado Department of Revenue before the deadline to discuss the debt and explore available solutions. Use the phone number listed on the notice to contact the relevant department. Be ready to explain your situation honestly and completely. Ask about payment plans, penalty abatements, hardship options, or dispute processes if pertinent to your problem.
Option C: Pay part of the balance by the deadline and contact the state about the remainder to show good faith. Make a partial payment demonstrating your willingness to resolve the debt. Contact the state to explain your situation and the financial constraints you face. Consider a formal payment plan to spread the remaining payments over a period of time.
Step 5: If you believe the amount is wrong, document your concerns
Gather the following evidence to support your position:
● Copies of tax records that support your calculation of what you actually owe.
● Any prior correspondence about this amount or related notices.
● Details of what you believe is incorrect, such as miscalculated income or improperly applied tax credits.
● Documentation of payments that the state may not have adequately recorded.
Understand that disputing the amount does not automatically stop the payment deadline, so you may need to explore both paying and disputing at the same time to protect yourself from enforcement actions.
Step 6: If you cannot pay by the deadline, contact the state immediately
Do not wait until after the deadline has passed to seek help. Contact the revenue department using the phone number listed on your notice and provide a clear explanation of your financial situation. Ask about payment plan options available to taxpayers in your circumstances.
Inquire about the possibility of extending the deadline based on your specific circumstances. Get the name of the person you spoke with and any case or reference number they provided for future reference. The Collections Department handles payment plan requests and can provide information about terms and conditions.
Step 7: Document all communication
Keep organized records of every interaction with the state:
● Copies of any letters you send to the state by mail.
● Written notes of all phone calls, including the date, time, person's name, and what was discussed.
● Proof of all payments made, including bank statements and confirmation numbers.
● Email confirmations if you communicate by email or through online portals.
This documentation becomes crucial if disputes arise about what was discussed or agreed upon.
Step 8: Follow up on any commitments made
If you agree to a payment plan or other arrangement with the state:
● Make payments on time according to the agreed schedule.
● Keep all payment receipts in a secure location.
● If circumstances change and you are unable to make a payment, please contact the state immediately rather than missing a payment without explanation.
Breaking a payment arrangement can trigger immediate enforcement actions that were previously suspended.
Step 9: Watch for follow-up notices
If you have made contact with the state or entered into an arrangement, remain vigilant:
● Continue watching for mail from the Colorado Department of Revenue.
● Read any follow-up notices carefully to ensure they reflect current agreements.
● Confirm that all notices accurately reflect the discussions you had with the representatives.
Step 10: Do not ignore additional notices
If you receive another notice after the deadline has passed, take immediate action:
● Read it immediately to understand what enforcement action may be starting.
● Contact the state immediately using the phone number provided.
● Do not assume the situation will resolve itself without your involvement.
Common Mistakes to Avoid
● Waiting until after the payment deadline to contact the state is a critical mistake that limits your options. Contact them before the deadline if you cannot pay in full to discuss alternative payment options.
● Assuming the amount on the notice is definitely wrong without checking your records first can waste valuable time during the notice period. Verify that the debt actually relates to a year you filed and that the amount is within a reasonable range based on your income.
● Sending payment to an address not listed on the notice can delay processing and cause additional issues with your account. Always follow the payment instructions on the notice itself exactly as written.
● Making a payment but not keeping proof of it can create problems if the state does not accurately record it in its system. Always save receipts, confirmation numbers, or bank statements showing the payment was sent and processed.
● Responding to a notice once enforcement actions have already begun, without understanding that you may need additional steps beyond paying the original notice, can complicate resolution and increase total costs.
Frequently Asked Questions
Does this notice mean the state is suing me?
No. A Notice of Demand for Payment is a collection notice, not a lawsuit or legal action in court. If the state filed a lawsuit, you would receive a summons and complaint, which are different documents served through formal legal proceedings. However, if this notice is ignored, a lawsuit is one possible next step the state may pursue.
Can I get the deadline extended?
The state may be willing to extend the deadline or work out a payment plan, but you must contact them before the deadline shown on the notice. There is no guarantee of an extension, but not asking for one does not guarantee you will not receive one. Be prepared to explain your circumstances and demonstrate reasonable efforts to resolve the debt.
What if I already paid this debt?
If you believe you already paid this amount, contact the Colorado Department of Revenue immediately with proof of your payment. Please provide the payment date, amount, and method (such as check number or credit card confirmation) so they can research your account and correct any recording errors.
Can I set up a payment plan instead of paying all at once?
Possibly. Contact the state using the phone number on the notice and ask about payment plan options available to taxpayers. The state does offer payment plans in some situations, but you must request this before the deadline and be prepared to provide financial information to support your request.
What happens if I miss the deadline but then pay the fee?
If you pay after the deadline, it is still better than not paying at all. However, paying late may result in additional penalties or interest being added to your balance under Colorado State tax law. Contact the state as soon as possible after missing the deadline to understand what additional amounts may be owed and to prevent further enforcement actions.
