Step-Up in Basis for Inherited Property: How It Saves You Money in Colorado
If you have inherited a home or other property in Colorado, you might worry about the taxes and financial stress it can bring. The stepped-up basis rule allows your tax basis to reset to the property's fair market value at the time of death. 2 This article explains how this tax benefit works, why it matters for capital gains taxes, and how it could save you money when selling inherited real estate in Colorado. 1
Key Takeaways
- The step-up in basis allows heirs to reset the property's tax value to its fair market price on the date of death. If you inherit a Denver home worth $500,000 that your parent bought for $50,000, your cost basis becomes $500,000.
- This rule can save you tens of thousands in capital gains taxes when selling inherited Colorado real estate.
- Colorado is a common law (not community property) state, so surviving spouses only receive a partial step-up on jointly owned property — not a full step-up on both halves.
- You must report sales using IRS Schedule D and Form 8949, and you may owe Colorado state income tax on any gain as well. Always use certified appraisals to prove fair market value at inheritance.
- Only inherited property receives this benefit. Gifted assets keep the original owner's cost basis, which can mean much higher capital gains taxes later.
What Is Step-Up in Basis?
Step-up in basis lets you reset the tax value of inherited property to its fair market price on the date of death. This rule can significantly lower your capital gains tax when you sell — a major benefit for Colorado heirs dealing with the state's appreciating real estate market.
Definition of "basis" and how step-up resets value
Your "basis" in property means the amount paid for it, plus costs like major improvements or closing fees. The IRS uses this number to calculate capital gains tax when the property is sold.
When you inherit real estate, federal law under Section 1014 of the Internal Revenue Code allows you to use the fair market value on the date of death as your new cost basis. This reset eliminates income taxes on appreciation that occurred during the deceased's ownership. For example, if a home in Aurora is worth $450,000 at the time of death and you later sell it for that same amount, there may be little or no taxable gain.
Example: Parent's home purchase and inheritance scenario
Angela bought her Colorado Springs home in 1975 for $50,000. In 2020, Angela passed away, and the fair market value of her home was $500,000. As her daughter, you inherited the house with a new cost basis of $500,000 due to the step-up in basis rule.
You sell the home two years later for $525,000. Your taxable gain is only $25,000 instead of a potential $475,000 without this rule. At combined federal capital gains rates and Colorado's state income tax rate of 4.4%, the savings are substantial. If a primary residence exclusion of $250,000 applies, your taxable gain may be eliminated entirely — saving tens of thousands of dollars compared to using Angela's original purchase price.
How Step-Up Works
The step-up in basis resets the tax basis of inherited real estate to its fair market value, often reducing your capital gains tax if you sell. Tax rules treat inherited assets very differently from gifts — a distinction that matters greatly for Colorado heirs.
Valuation process and inheritance rules
- Executors must establish the fair market value (FMV) of the property as of the decedent's date of death, typically using a certified independent appraisal or comparable sales data from the local Colorado market.
- An alternate valuation date — exactly six months after death — may be used if property values have dropped, potentially reducing capital gains taxes when you sell.
- The cost basis for inherited property equals its FMV at date of death, not what the decedent originally paid.
- Required documentation includes a certified appraisal, the death certificate, deeds, closing statements, and records of any improvements made to the property.
- In Colorado, inherited property passes through the probate process overseen by the district court in the county where the decedent lived. Colorado uses the Uniform Probate Code, which provides a relatively streamlined process compared to many other states.
- Only inherited property receives a step-up in basis. Gifted assets use the original carryover basis, which can result in higher capital gains taxes later.
- Report the sale on IRS Schedule D and Form 8949. You will also need to report any gain on your Colorado state income tax return, as Colorado taxes capital gains as ordinary income at a flat rate of 4.4%.
- If Schedule A to Form 8971 is issued by the executor, use the same value reported on the estate tax return to avoid IRS penalties.
Difference between inherited assets and gifted assets
Inherited assets receive a step-up in basis to fair market value at the date of death. 2 If your parent bought a home in Lakewood for $100,000 and it is worth $400,000 when you inherit it, your new tax basis becomes $400,000 — and you only owe capital gains tax on appreciation above that amount.
Gifted assets keep the original owner's cost basis. If someone gifts you Colorado real estate during their lifetime, you take over their original purchase price. When you later sell, all past appreciation is taxed under your name — often resulting in a far larger tax bill than if you had inherited the same property through an estate. 1
Step-Up in Basis for Married Couples in Colorado
Because Colorado is a common law state — not a community property state — surviving spouses receive only a partial step-up in basis on jointly owned real estate. Understanding this distinction is important for estate planning in Colorado.
Partial step-up in Colorado (a common law state)
In Colorado, when spouses hold property as joint tenants with right of survivorship, only the deceased spouse's half of the property receives a step-up in basis. The surviving spouse's half retains its original cost basis.
For example, if you and your spouse purchased a Denver home for $400,000 and it is worth $600,000 at your spouse's death, only half of the property steps up. Your new combined tax basis becomes $500,000 — not the full $600,000 fair market value. This means you could still face capital gains taxes on $100,000 worth of appreciation tied to your original half if you later sell.
Some Colorado couples use estate planning tools such as revocable living trusts or spousal lifetime access trusts to better manage this outcome. Consulting a Colorado estate planning attorney can help you structure ownership in a way that minimizes future capital gains exposure.
Community property trusts as an option
While Colorado is not a community property state, some states allow couples to hold assets in a community property trust that provides a full step-up on both halves at death. Colorado residents may explore whether such structures are available through trusts established in states that permit them, but this requires guidance from a qualified estate attorney familiar with both Colorado and the relevant state's laws.
Selling Inherited Property in Colorado
Selling inherited Colorado real estate often results in lower capital gains taxes because of the step-up in basis rules. Still, Colorado heirs should understand both federal and state tax obligations before deciding when and how to sell.
Long-term capital gains treatment
Inherited property automatically qualifies for long-term capital gains tax rates — regardless of how quickly you sell after inheriting. Federal long-term rates for 2025 are 0%, 15%, or 20% depending on your income. High earners may also owe a 3.8% Net Investment Income Tax.
At the state level, Colorado does not have a separate capital gains tax rate. Gains are taxed as ordinary income at Colorado's flat income tax rate of 4.4%. When combined with federal taxes, the step-up in basis can still generate significant savings by reducing or eliminating the taxable gain entirely — especially in Colorado's high-appreciation markets like Denver and Boulder.
Considerations for selling quickly or holding
Selling inherited property shortly after the Colorado probate process closes often minimizes capital gains tax. If you sell within 6 to 12 months of inheritance, the stepped-up basis means there is typically little or no taxable gain. 3
Holding the property comes with ongoing costs: Colorado property taxes, homeowner's insurance, HOA fees (common in many Denver-area communities), and maintenance can run $500 to $2,000 or more per month. Out-of-state heirs often find these expenses difficult to manage from a distance. Renting the property before selling can trigger depreciation recapture, increasing your federal tax liability. When multiple heirs inherit together, disagreements about whether to sell or hold can further complicate and delay decisions.
Tax Reporting for Inherited Property Sales in Colorado
When you sell inherited real estate in Colorado, you must report the sale at both the federal and state level. Working with a CPA or tax attorney familiar with Colorado tax law helps ensure accuracy and avoid penalties.
Required forms and professional help
- Report the sale on IRS Schedule D (Form 1040) and Form 8949 for federal purposes.
- Report any taxable gain on your Colorado state income tax return (Form DR 0104). Colorado taxes capital gains as ordinary income at 4.4%.
- Use the fair market value at the date of death — confirmed by a certified appraisal — as your cost basis.
- If an estate tax return was filed and Schedule A to Form 8971 was issued, your reported basis must match that value to avoid IRS penalties.
- Colorado does not impose a separate state estate tax or inheritance tax, which simplifies reporting compared to some other states.
- Note that Colorado does require a withholding on real estate sales by nonresident sellers. If you are an out-of-state heir selling Colorado property, you may need to withhold and remit a portion of the sale proceeds to the Colorado Department of Revenue at closing.
- Consult a Colorado estate attorney or CPA for complex situations involving trusts, multiple heirs, or large investment portfolios. Many Denver-area professionals specialize in estate and probate tax matters.
Insights for Colorado Inherited Houses
Inherited houses in Colorado often come with surprises. Many properties are 20 to 40 years old and may need significant repairs before going on the market. Monthly carrying costs for taxes, insurance, and maintenance are real — and Colorado property taxes, while not the highest nationally, vary significantly by county and can still add up quickly.
Disagreements among heirs can stall decisions and increase holding costs. Confusion about the step-up in basis often creates unnecessary fear of capital gains taxes where little or none may actually be owed. A proper FMV appraisal from a Colorado-licensed appraiser is essential for protecting yourself from unexpected tax bills.
Selling quickly for cash can provide relief from monthly carrying costs and the emotional difficulty of managing an inherited property — especially for families navigating Colorado's probate process while also grieving. Working with a local estate attorney and CPA ensures the paperwork goes smoothly for everyone involved.
Conclusion
The step-up in basis offers real, meaningful savings for Colorado heirs. By resetting your cost basis to fair market value at the date of death, you can often avoid or significantly reduce capital gains taxes — both at the federal level and under Colorado's 4.4% income tax rate. This rule helps families preserve more of their inheritance and make smarter estate planning decisions.

FAQs
1. What does step-up in basis mean for inherited property in Colorado?
It raises your tax basis to the property's fair market value on the date of death. This new cost basis lowers your taxable gain when you sell — whether you owe federal capital gains tax or Colorado state income tax on the proceeds.
2. Does Colorado have an inheritance tax or estate tax?
No. Colorado does not impose a state inheritance tax or a separate state estate tax. However, federal estate tax rules still apply to larger estates, and any capital gains from selling inherited property are subject to Colorado's 4.4% flat income tax rate.
3. Is step-up in basis available for all types of inherited assets in Colorado?
Most real estate and investment accounts benefit from the step-up under federal law. Some exceptions apply to retirement accounts like IRAs and certain depreciated assets.
4. How does Colorado's common law status affect my step-up in basis?
Because Colorado is a common law state, only the deceased spouse's share of jointly owned property receives a step-up in basis. The surviving spouse's share keeps its original cost basis, which can result in higher capital gains taxes when the property is eventually sold.
5. What if I am an out-of-state heir selling Colorado property?
Nonresident sellers of Colorado real estate are generally required to withhold a portion of the sale proceeds and remit it to the Colorado Department of Revenue at closing. Consult a Colorado CPA or closing attorney to ensure compliance.
6. Should I sell an inherited Colorado home quickly or hold it?
Selling soon after probate often minimizes capital gains tax because prices typically haven't moved far from the stepped-up basis. Holding adds ongoing costs and potential depreciation recapture issues if the home is rented. A financial advisor familiar with Colorado real estate can help you weigh the options.
