Bills are issued by the Department of Revenue when you do not pay your tax in full when you file your return, if you paid late and owe penalty and interest or if you did not file a return and the Department filed one for you. When a Notice of Deficiency is issued, you have 30 days to notify the department if you disagree with the bill. Be sure to read the notice carefully to understand your rights and to see what documentation is required.
If you do not pay or protest the bill within the allotted time, the Department will issue a Final Determination and Demand for Payment. Should you fail to pay the balance in full or start a monthly installment plan (see Pay Your Tax Bill above), we may take certain actions to collect your unpaid taxes. For example,
It is important to contact us and make arrangements to pay the tax due voluntarily. Penalty and interest will continue to accrue until the tax is paid in full. For more information about your bill, read the topic Respond to Billing Notices above or call the number listed on your bill. To request a monthly installment plan, call 303-205-8291.
The Department may garnish the wages of any taxpayer who has failed to pay their taxes after a Final Notice and Demand for Payment is issued. We will usually send a Notice of Intent to Issue Garnishment to the taxpayer’s last known address before we actually start garnishing their wages. This is a courtesy letter to allow the taxpayer one final chance to pay their tax debt before we notify their employer. At this stage, the taxpayer has 30 days from the date of the notice to pay the balance in full or resolve it.
Once a garnishment notice has been sent to your employer, the garnishment will continue until the balance is paid in full. The department generally sets the garnishment to be 25% of your disposable pay. You cannot request a payment plan at this time and sending a partial payment will not prevent future wages from being garnished. The garnishment will continue until it is paid in full through your wage assignment, or if you remit certified funds. Only a bank/cashier’s check or a money order can be accepted as certified funds. We strongly suggest that you DO NOT mail your certified payment and DO NOT pay via Revenue Online.
If your wage garnishment causes you a financial hardship, you may request a reasonable accommodation. To request such a review, you must submit:

The Department of Revenue may refer your unpaid tax debt to a third-party collection agency [§39-21-114 (8), C.R.S.]. These agencies are authorized to enforce collections on behalf of the department. Once your debt has been placed with one of the following agencies, you must work directly with them to pay your tax debt.

Judgments and Liens
The Colorado Department of Revenue is authorized to file a judgment/lien to collect your unpaid tax debt [§39-21-114 (3), C.R.S.]. We will usually send a Notice of Intent to Issue Judgment/Lien to the taxpayer’s last known address. This is a courtesy letter to allow the taxpayer one final chance to pay their tax debt. At this stage, the taxpayer has 10 days from the date of the notice to pay the balance in full with certified funds. Only a bank/cashier’s check or a money order can be accepted as certified funds. DO NOT mail your payment. Once filed, a judgment/lien attaches to all of your assets (such as property and vehicles) and will prevent you from selling them without first paying your tax debt.
