Colorado draws steady migration from states that treat marital assets as community property. A new state law changes how some of that property is handled when the first spouse dies, and it now reaches real estate sitting in Colorado regardless of where the owner was living at the end of life. For couples who bought here after years in California, Texas, Arizona, or Nevada, that distinction carries real tax weight.
What House Bill 26-1189 Changed
The governor signed the bill on April 13, 2026. It took effect August 12, 2026, and it amends a single statute, C.R.S. 15-20-103, which defines the property covered by Colorado’s Uniform Community Property Disposition at Death Act.
The earlier version applied only when the decedent was domiciled in Colorado at death. A couple could buy a home in Larimer County while living in Arizona, move away again, and leave that Colorado property outside the act. The new subsection closes that gap. Real property located in Colorado and traceable to community property is now covered no matter where the decedent was domiciled, along with the rent, profit, and appreciation derived from it. The full text is available through the Colorado General Assembly bill record.
Why Character Matters More Than the Deed
A deed tells you who holds title. It rarely tells you whether the underlying property is community property, and that second question drives the tax result.
The Basis Difference
When property is community property, both halves adjust to fair market value at the first spouse’s death. With ordinary joint tenancy, only the deceased spouse’s half receives that adjustment. The survivor carries the original basis forward on everything else. That gap can mean a substantial capital gains bill years later, when the home is finally sold. The IRS explains the general rules in Publication 551 on basis.
Who Should Review Their Documents
Not every Colorado homeowner is affected. The change matters most for a narrow group:
- Couples who purchased Colorado real estate while domiciled in a community property state
- Surviving spouses holding property acquired during a marriage that began in one of those states
- Families who signed a partition or reclassification agreement years ago and never revisited it
- Anyone whose will or trust was drafted without tracing where each asset was acquired
Tracing that history takes deed records, purchase dates, and sometimes correspondence going back decades. A Loveland estate planning attorney can work through that record with you and document the property’s character in writing, rather than leaving a presumption for a family member to reconstruct later.
