Senior Deferral Information

Senior Deferral Information

The Treasurer’s Office is no longer accepting applications for 2022 deferrals (for tax year 2021 taxes). Any new requests will be considered for next year’s program.

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. The Boulder County Treasurer’s Office collects the information and sends it to the State of Colorado, which manages the program, determines eligibility, and notifies the county treasurers who has been approved or disapproved.

The 2022 interest rate is 1.375%.

General requirements

  • You must be 65 years old on or before January 1 of this year
  • You cannot be earning income from the property (e.g., renting the property), but you can have a home office
  • 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)
