Payment Options

You have the following options to pay your tax:

1. Mail in a check.
   You need to attach Payment Voucher (Form DR0900) 

   Mail check to:
   Colorado Department of Revenue
   Denver, CO 80261-0008

2. Online Tax PaymentNo matter how a Colorado personal income tax return is filed, electronically or on paper, taxpayers can pay tax owed through the Colorado Online Tax Payment service.  And individuals filing their tax returns via the Colorado NetFileonline tax filing system have the option while they’re in NetFile to pay their tax electronically using a Visa, MasterCard or electronic check.

   To make an electronic payment, users simply complete their filing through the NetFile system and select the online payment link. Or, visit the Colorado Online Tax Payment (https://www.colorado.gov/apps/dor/tax/netfile/welcome.jsf ) service. Either way, taxpayers will be asked to provide basic information to process the payment and submit the transaction. All payments are processed by Colorado.gov’s secure payment processing software and can be made using a credit card or electronic check. In most cases, the payment information is processed by the Department of Revenue and applied to the taxpayer’s account within 24 hours.  There is an administrative processing fee to use this service.  The fee is the amount due plus $ .75 multiplied by 2.25%.  However, if you choose to pay with cash in the form of an eCheck, the administrative processing fee is discounted to $1.00 per transaction.  This fee is paid to a third party that provides these services for Colorado.gov.

3. Payment PlanHow do I make installment payment arrangements?
   File your income tax return on or before the April 15th filing deadline. Include on the paper or electronic return the amount you owe. Pay as much as you can of the amount you owe by the filing deadline.  The ‘Amount You Owe’on your individual income tax return is your first balance due notice.
   Bills will start to be mailed in early July. When you receive the second notice, your billing information is in our computer system and you may set up an Agreement to Pay. There are three methods of setting up an installment plan.
   • Use our Income Tax Account Information (https://www.myincometax.state.co.us/index.asp) service.
   • Use our IVR system at (303) 238-FAST (3278).
   • Contact our Call Center at (303) 238-7378.

If you want to start making payments on your account prior to receiving the bill, you can mail in your payment attached to your Individual Income Tax Payment Voucher (DR 0900) which is included in the Colorado 104 booklet. Make sure you put your social security number (write the primary social security number if it is a joint filing) on the bottom of your payment check and the tax year to which the payment applies.
