Life often unfolds unexpectedly. A sudden job loss, a medical emergency, or an unexpected expense can throw even the most responsible taxpayer off track. You're not alone if you're behind on your state taxes and unable to pay the full balance to the Colorado Department of Revenue.

What's the good news? Colorado offers a way to catch up without sinking further into financial stress. Through what’s known as a tax payment plan or installment agreement, you can pay off your back taxes gradually in monthly installments that match your budget. Whether you’re dealing with a recent tax bill or a debt hanging over your head for a while, this option can help you avoid aggressive collection actions like wage garnishment, property liens, or bank account levies.

Getting started isn’t as complicated as it might seem. You can apply through Colorado’s Revenue Online portal or talk directly with someone in the Collections Section. This guide will walk you through the process, covering everything from who qualifies to what to do if things go wrong. If you’re feeling overwhelmed by your tax situation, don’t worry. You’ve got options, and this breakdown is here to help you move forward confidently.

What Is a Colorado Tax Payment Plan?

A tax payment plan in Colorado lets you pay your state tax debt over time, rather than all at once. It’s designed for people and businesses who’ve received a tax bill from the Colorado Department of Revenue (CO DOR) but can’t afford to pay it in full by the due date. Instead of risking collection actions, you can spread your balance through structured monthly payments that better fit your budget.

These plans can be used to settle various tax types, including personal income tax and business-related taxes. To stay in good standing, you’ll need to make your full payments on time every month and stay current with all future tax filings. While Colorado doesn’t charge a setup fee for these plans, remember that interest and penalties will still accrue until the full balance is paid. If you're owed a state refund, Colorado may automatically apply it to your outstanding balance to help pay it down faster.

The minimum monthly payment depends on how much you owe and the agreement's time frame. When ready, log into your Revenue Online account or contact the Collections Section to initiate a plan request. It’s a straightforward way to manage your tax debt responsibly, avoid being sent to a third-party collection agency, and regain financial control one step at a time.

Colorado Tax Payment Plan Types

To assist taxpayers in paying off their outstanding tax debt, the Colorado Department of Revenue provides short-term and long-term installment agreements. Colorado’s payment plans are designed to meet people where they are financially, whether you’re a business owner dealing with past-due sales tax or an individual trying to catch up on personal income taxes. How much you owe, what your finances look like, and how much you can reasonably pay each month will all factor into what kind of plan you qualify for and how long it’ll last. 

Short-Term vs. Long-Term Payment Plans

  • If you can pay off your full tax balance in just a few months, a short-term plan might be your best bet. You’ll pay more each month but save money in the long run by paying less interest.

  • A long-term plan might be better if your budget is tight and you need more time to pay off your tax debt. You'll make lower monthly payments, which can ease the pressure, but just know that interest will continue to build the longer your balance remains unpaid.

Both plan types require you to meet the Colorado Department’s minimum monthly payment and remain current on all subsequent tax filings.

The Importance of Selecting the Correct Plan

No matter which plan you choose, following the terms exactly is imperative. If you fall behind on payments or forget to file new returns, the state may issue a warning, and in some cases, it’ll send your case to a collection agency. By selecting the appropriate plan and maintaining compliance, you can resolve your tax situation and responsibly safeguard your finances.

Qualifications for Eligibility

To qualify for a Colorado tax plan, you must meet specific requirements established by the Colorado Department of Revenue.

Basic Requirements

  • Please make sure you’ve received an official tax bill from the Department. You can’t request a payment plan until you have this.

  • Your balance must be over $50, and your plan needs to include at least three monthly payments.

  • To get your application approved, please ensure that all past-due and current-year tax filings are up to date.

If your tax bill is too small, you must pay it in full rather than use an installment plan.

Additional Considerations for Business Taxpayers

Eligibility for taxpayers with business tax debt is often more complex than for individuals and usually requires review by a compliance agent. If you've previously defaulted or owe a significant balance, you may be asked to submit supporting financial documents before a payment plan can be approved.

To keep your Colorado tax payment plan active and avoid collection actions or a final notice:

  • Ensure your business stays current on all future tax filings, including sales and withholding taxes, so your account remains in excellent standing.

  • Always make your scheduled payments on time to show the Department that your business is complying with the plan's agreed-upon terms.

  • If you receive a letter or notice from the Colorado Department of Revenue, respond quickly and thoroughly, even if unsure about the next steps—communication helps avoid escalation.

Financial Difficulties and Adapted Contracts

Submit Form DR 6596 (Statement of Economic Hardship) to request hardship consideration formally. Both individuals and businesses may qualify.

Supporting Documentation

  • Bank statements

  • Recent pay stubs or proof of income

  • Documentation of expenses (e.g., medical bills, dependent care)

What Takes Place If Your Plan Is Not Completed

There are serious consequences for defaulting on a tax payment plan in Colorado.

When Is a Plan Considered a Default?

Your tax payment plan in Colorado is considered in default if you don’t meet the agreement's essential terms. This can happen in the following situations:

  • If you miss a scheduled full monthly payment, the plan may be flagged as noncompliant for even a few days.

  • If you fail to file required future tax returns by their deadlines, the Department will view your account as out of compliance.

  • If you don’t return your signed agreement documents, the payment plan won’t be activated, and the Department can cancel your request.

What the Department May Do After Default

Once your payment plan is officially in default, the Colorado Department of Revenue may take the following actions:

  • If your plan defaults, the Department may cancel it, meaning your entire tax debt, including interest and late fees, becomes due immediately.

  • Since the tax was initially assessed, you may be required to pay the full balance immediately, including all accumulated interest and penalties.

What Happens After Default?

You’ll usually receive a final notice from the Colorado Department of Revenue warning you that your tax payment plan is at risk. If you don’t act quickly, the state may pursue more aggressive collection efforts to recover the balance owed. These actions may include

  • The state may place a property lien on your home, land, or other real estate until the tax debt is paid in full.

  • Bank levies can be issued, allowing the state to withdraw funds directly from your checking or savings account to cover your outstanding balance.

  • If the state issues a wage garnishment, it’ll take a portion of your paycheck each pay period and apply it toward your tax balance. It’s automatic and financially disruptive, so it’s best to stay ahead of your plan terms if possible.

  • If your case escalates, it may be handed over to a third-party collection agency, adding additional pressure and costs.

Can You Reinstate a Canceled Plan?

Yes, you may be able to reinstate a canceled tax payment plan in Colorado, but it’s essential to act quickly and take the proper steps:

  • Please contact the Collections Section as soon as possible to discuss your situation and verify whether your payment plan remains eligible for reinstatement.

  • Be ready to make up any missed payments or propose updated terms that reflect your current financial circumstances.

  • If your default was due to hardship, you may need to submit updated financial documentation, such as pay stubs or Form DR 6596, to support a request for modified payment terms.

Checklist for Pre-Application

Review your eligibility and gather the necessary documents before applying for a tax payment plan in Colorado. Submitting a complete and accurate request increases your chances of approval and helps avoid unnecessary delays. Here's what you need to do before starting your application:

1. Confirm Eligibility

To qualify for an installment agreement with the Colorado Department of Revenue, you must meet specific criteria:

  • You must first receive an official tax bill from the state. This notice outlines your unpaid balance and is required before establishing a payment plan.

  • Your tax debt must be more than $50. The Department requires full payment rather than monthly installments if you owe less than that.

  • Your plan must include at least three scheduled monthly payments. The Department does not allow single- or two-payment arrangements.

  • Your previous and current tax returns must be filed on time and fully up-to-date before your application can be accepted.

  • You must demonstrate that you can financially make consistent, full monthly payments for the duration of the agreement.

  • You cannot have any active lawsuits or enforcement actions related to your tax situation at the time of your application.

If you meet all these criteria, you can request a payment plan that fits your financial circumstances.

2. Gather Taxpayer and Account Information

Before beginning your application, be sure to collect all of your personal and tax account details. This includes your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), your most recent tax bill or notice, and your contact information, such as your phone number, mailing address, and email. If you plan to apply online, you must create or log in to a Revenue Online account. You should be prepared to supply your bank account information to set up automatic payments.

3. Assess Your Financial Capacity

Please carefully review your finances before proposing a monthly payment amount. You’ll need to know all household income sources, including wages, Social Security, and pension income. List your fixed monthly expenses—rent or mortgage payments, utilities, transportation costs, and insurance. Don’t forget to include any unusual or necessary expenses like medical bills or dependent care. Proposing a payment you can afford is essential; overcommitting could result in default, penalties, or being referred to collections.

4. Prepare Financial Hardship Documentation (If Needed)

You must submit proof of your hardship if you're struggling financially and need a modified installment agreement. This includes a completed Form DR 6596 (Statement of Economic Hardship), your most recent pay stubs, 30 to 60 days’ worth of bank statements, and documents showing significant obligations like child support, medical bills, or student loans. If you feel it’s helpful, include a brief letter explaining your financial situation. You should keep up your current plan's regular payments while your request is reviewed to prevent cancellation.

5. Verify Final Readiness

Before submitting your application, double-check that you’ve reviewed your tax balance through Revenue Online or on the mailed bill. Make sure the payment plan you’ve selected meets the Department’s minimum requirements and that you understand interest and penalties will continue to accrue until the full amount is paid. Once your plan is approved, please return any signed agreement documents at your earliest convenience. You should know how to reach the Collections Section or your assigned compliance agent if you run into questions. Lastly, ensure all your state tax returns have been filed through the current tax year.

Frequently Asked Questions (FAQs)

When can I ask for a tax payment plan for this year?

You can request a tax payment plan for Colorado the day after the annual tax deadline, typically around April 15. Once the Colorado Department of Revenue sends your tax bill, you may apply through Revenue Online or by calling the Collections Section. Don’t wait too long—getting a payment plan early can help reduce stress, avoid penalties, and give you more manageable monthly payments for your outstanding tax debt.

What is the smallest amount I can pay each month?

The Colorado Department of Revenue determines your minimum monthly payment based on your total tax debt and how long you need to pay it off. All payment plans must include at least three monthly payments. You might need to pay in full if your tax bill is small. Your proposed amount must be realistic and approved by the department to keep your tax payment plan active and avoid default.

Why was my refund applied to my payment plan by the state?

If you've enrolled in a tax payment plan in Colorado, the state may automatically apply future tax refunds to lower your outstanding balance. This helps pay off your tax debt faster but doesn’t replace your required monthly payments. You must continue making timely payments, even if your refund is applied. This process ensures the Colorado Department of Revenue collects unpaid taxes efficiently while keeping your plan active.

What occurs if I cease filing tax returns or fail to make a payment?

Missing a monthly payment or failing to file new tax returns on time may result in defaulting on your tax payment plan in Colorado. If this happens, the Colorado Department of Revenue can cancel your agreement and demand full payment, which may involve using wage garnishment or property liens. To avoid these actions, always follow your plan’s terms, file future returns promptly, and contact the Collections Section if financial problems threaten your ability to pay.

If I run into financial difficulties, can I change my plan?

If your financial situation changes and you can’t keep up with your monthly payments, you may request modified terms. To adjust your tax payment plan in Colorado, file Form DR 6596 and provide proof of financial hardship, such as pay stubs or bank statements. A compliance agent will review your case. Continue making your current payments during the review to avoid default. Modified plans can help reduce financial pressure.

How can I arrange a payment schedule if I have business tax debt?

Businesses with Colorado tax debt must contact a compliance agent directly at the Department of Revenue. Call (303) 866-3711 to discuss your balance and financial status and set up a tax payment plan that fits your business’s needs. Business taxpayers cannot use Revenue Online to apply. After approval, you’ll receive documents to sign and return. Compliance with business tax filings and payments helps avoid collections and enforcement actions.

What caused my payment coupons to stop coming in?

If your payment coupons suddenly stop arriving, it could mean your tax payment plan for Colorado has been canceled. This may happen due to missed payments, failure to file new tax returns, or unreturned agreement documents. Please contact the Collections Section promptly to verify the status of your plan. You can often reinstate your plan or reapply if your tax situation qualifies. Acting quickly helps avoid additional penalties or collections.
