Online Payments & Fees

Online payments are now available in COSTIS-IA!  Invoices will be used in all cases of payments including permit applications, NOVs/Enforcements and tank registrations. When invoices are received (either by email or by mail) please closely review the online payment instructions prior to attempting to make payments. If you hae questions, concerns, or suggestions, please submit a completed COSTIS-IA Help Ticket.  Please note: All previous bookmarked links have been deactivated, please update accordingly.

Important: Due to integration with the new COSTIS-IA system, you may not see your payment reflected on your account immediately. You may also receive an error message, however please do not submit a payment more than once to avoid multiple payments. If you have questions or concerns about whether your payment was received, please contact Sandi Johnson at sandi.johnson@state.co.us. We appreciate your patience and understanding during this transition period.
