Seniors, Veterans, and Active-Duty Military
Beginning in 2023, the Colorado State Treasurer’s Office will run the program for the Senior Property Tax Deferral and Active Military Property Tax Deferral programs, including processing applications, which was formerly done by our office.
While the state has not yet published the 2023 deferral interest rate, the law says that the rate is “equivalent to the rate per annum on the most recently issued ten-year United States treasury note, rounded to the nearest one-tenth of one percent, as reported by the ‘Wall Street Journal’, as of February 1” (C.R.S. 39-3.5-105(5)). The 10 year treasury note sold on January 17 at an interest rate of 4.125%.
