The Colorado Revised Statutes - 39-11-119 - provide that a holder of a certificate of purchase may pay any subsequent taxes on the property on which the buyer has an unredeemed certificate, and that this payment will be endorsed on the certificate and the tax lien sale book of record in the Treasurer's Office.

The payment is made to protect your certificates and to prevent the subsequent delinquent taxes from being sold again at the tax lien public auctions.  Payment is recorded on the certificate and on the tax lien sale book to insure that you will be reimbursed for this additional payment in the event of a redemption.  This fee for the endorsement of these payments is $5.00 per endorsement.  This fee will also be recovered on redemptions.  Current general property tax payments can be endorsed on to certificates for special assessment if you desire. Delinquent Local Improvement installments may be endorsed on to general tax certificates.  Certificates must be brought in, left, and processed in the order they are received.

Subsequent payments of delinquent taxes endorsed on certificates purchased in October 2018 draw interest at the rate of 1% per month or fraction thereof (12% per annum), from the date of payment. This interest is computed on a monthly basis to the date of redemption.

This may be done at any time, but accrues interest from date of payment to date of redemption. Buyers wishing to make subsequent tax payments should bring or send their certificates to the following:

City and County of Denver

Treasury Division/Special Accounts Unit

201 West Colfax Ave, Dept 1009, MC 401, Wellington E Webb Municipal Office Building

Denver, CO  80202-5330

(720) 913-9500

Treasury will determine the amounts required and will notify buyers so that payment can be made.  We will then process the payments and make the necessary entries to the tax lien sale books.

For payment of general taxes, most buyers bring their certificates in during the last two weeks of July.  Processing takes several weeks.  If redemptions are received during this time, we pull the certificate and mail a check to the taxbuyer.
