Senior Deferral Information

What is the senior tax deferral program?

The senior tax deferral program is offered by the State of Colorado. It allows you to postpone tax payments on your primary residence until you sell your property, or your estate is settled after your death. Interest is applied to the amount you defer. Each year, you can defer either the whole amount of your taxes, or half your taxes.

In the past, this program was managed jointly between the County and State Treasurer’s Offices. Beginning in 2023, the State Treasurer took over all aspects of the program, including the deferral application process.

You can find information and sign up for the program at the Colorado property tax deferral program website.

General requirements

  • You must be at least 65 years old before January 1 of this year
  • If your property is in a trust you must be named the trustee and the beneficiary of the trust
  • If you have a reverse mortgage you likely cannot receive tax deferral (your lender must agree to subordinate)
