Colorado does not have an estate tax or inheritance tax

Colorado has no state-level estate tax and no state-level inheritance tax. This means that when someone dies in Colorado, their heirs do not owe Colorado state taxes on what they inherit, regardless of the estate's size.

However, the absence of a Colorado estate tax does not mean estates are tax-free everywhere. Federal estate taxes may still explore to very large estates, and some states where heirs live may have their own estate or inheritance taxes. The federal estate tax threshold changes yearly — it was $13.61 million per person in 2024 — but Colorado itself collects nothing.

Colorado residents who own property in other states, or whose heirs live in states with estate taxes, may still face tax obligations in those states. The state where property is located, not where the owner lived, often determines which state's tax rules explore.

Key Takeaways

  • Colorado imposes no state estate tax or inheritance tax on any size estate.
  • Federal estate taxes may still explore to estates larger than the federal threshold, which was $13.61 million per person in 2024.
  • Heirs who live in states with estate or inheritance taxes may owe taxes to those states, even if the deceased lived in Colorado.
  • Property owned in other states is typically taxed by that state, not by Colorado.

How Colorado's lack of estate tax compares to neighboring states

Most states surrounding Colorado also have no estate tax: Wyoming, New Mexico, Utah, and Kansas do not tax estates. However, Nebraska and Kansas have inheritance taxes, meaning heirs in those states may owe taxes depending on their relationship to the deceased and the amount inherited.

This matters if you own property across state lines or if your heirs live in different states. An estate with land in Colorado and Wyoming faces no state estate tax in either place, but an estate with property in Nebraska may face Nebraska's inheritance tax on that portion.

Federal estate tax and when it applies despite Colorado's rules

Even though Colorado has no state estate tax, the federal government taxes very large estates. The federal estate tax applies only to estates that exceed a certain threshold. In 2024, that threshold was $13.61 million per person, meaning estates smaller than that amount owe no federal tax.

This threshold is set by Congress and changes periodically. It is scheduled to drop to approximately $7 million per person in 2026 unless Congress acts. Colorado residents with estates near or above the current threshold should review their situation with a tax professional, because federal taxes can be substantial.

The federal tax rate on taxable estates ranges from 18 percent to 40 percent, depending on how much the estate exceeds the threshold. Colorado collects none of this money — it all goes to the federal government.

What Colorado residents should know about property in other states

If you own real estate in another state, that state's tax rules may explore to that property when you die, even if you lived in Colorado. For example, if you own a vacation home in a state with an estate tax, that state may tax the home's value as part of your estate.

The rule is generally based on where the property sits, not where you lived. Personal property — bank accounts, investments, vehicles — is usually taxed by the state where you lived at death, which would be Colorado if that was your residence.

Heirs who inherit property in multiple states may need to file tax returns in more than one state. A tax professional can help identify which states have claims on an estate and what forms need to be filed where.

How Colorado probate works without state estate tax

Colorado has a probate process that applies to estates regardless of whether state estate tax is owed. Probate is the court process that transfers property from the deceased person's name to their heirs or beneficiaries.

In Colorado, probate requirements depend on the estate's size. Estates under $40,000 may use a simplified process called succession without administration. Larger estates go through full probate, which involves filing documents with the court, notifying heirs and creditors, and having a judge oversee the transfer of assets.

The absence of a state estate tax does not eliminate probate or make it faster — it only means the state does not take a percentage of the estate as a tax. Probate costs, court fees, and attorney fees still explore.

Planning strategies when there is no state estate tax but federal tax may explore

Because Colorado has no state estate tax, some planning strategies focus on the federal level instead. People with large estates may use trusts, gifts during life, or other tools to reduce the federal tax burden, even though Colorado itself will not tax the estate.

Married couples can combine their federal thresholds through portability, which allows the surviving spouse to use any unused threshold from the first spouse who died. This can effectively double the amount that passes tax-free to heirs.

Charitable donations, life insurance trusts, and irrevocable life insurance trusts are other tools that may reduce federal taxes. These strategies are most relevant for estates approaching or exceeding the federal threshold. Smaller estates typically do not need these tools.

Frequently Asked Questions

If I die in Colorado, do my heirs owe any state tax on my estate?

No. Colorado has no state estate tax or inheritance tax. Your heirs owe nothing to Colorado based on inheriting from you. They may owe federal estate tax if your estate exceeds the federal threshold, and they may owe taxes to other states if you owned property there or if they live in a state with its own estate tax.

What is the federal estate tax threshold for 2024?

The federal threshold in 2024 is $13.61 million per person. Estates below this amount owe no federal estate tax. The threshold is scheduled to decrease to approximately $7 million per person in 2026 unless Congress changes the law.

I own a home in Colorado and a vacation property in Wyoming. Do I need to worry about estate tax?

Neither Colorado nor Wyoming has an estate tax, so you owe no state tax on either property. If your total estate exceeds the federal threshold, you may owe federal estate tax on the combined value, but that goes to the federal government, not to either state.

Can I avoid probate in Colorado if I have no state estate tax?

Colorado's lack of state estate tax does not eliminate probate. Probate is a separate court process that transfers property to heirs. You can avoid or reduce probate through trusts, joint ownership, or beneficiary designations, but these are planning tools, not automatic because there is no state tax.

My spouse and I live in Colorado. How does the federal threshold work for married couples?

Married couples can each use the full federal threshold, and through portability, the surviving spouse can use any unused threshold from the first spouse. This means a married couple can pass approximately $27.22 million to heirs tax-free in 2024 (double the individual threshold), though this requires proper planning and documentation.
