Taxes on Selling an Inherited House: What You'll Owe in Colorado

Losing a loved one is hard enough without worrying about taxes on selling an inherited house in Colorado. One key fact: most people don't owe huge amounts because the property's value resets to its fair market price at the time of inheritance. 1 This guide covers what Colorado heirs need to know — from stepped-up basis rules to state-specific capital gains treatment — so you can avoid costly surprises. 2
Key Takeaways
- The IRS uses a stepped-up basis for inherited houses. Your cost basis becomes the fair market value at the owner's death. You only pay capital gains tax on profit above that amount.
- Federal estate tax generally does not apply unless the estate exceeds $13.61 million per person in 2024. Most Colorado heirs will not owe federal estate taxes.
- Colorado does not have a state inheritance tax or a separate state estate tax, which is good news for most heirs in the Denver metro and beyond.
- Colorado taxes capital gains as ordinary income at the state level. The flat state income tax rate is 4.4% as of 2024, applied to your net capital gain.
- Inherited property always qualifies for long-term capital gains rates (0%, 15%, or 20% federally) regardless of how quickly you sell after inheriting.
- Keep all records: Get a professional appraisal at the date of death, save receipts for repairs and selling expenses, and consult a Colorado estate planning attorney or CPA.
Understanding inherited property taxes can feel overwhelming during an already difficult time.
Selling an inherited house in Colorado can trigger taxable income, even if you never expected it. Most heirs do not owe taxes until they actually sell, but you could face capital gains tax depending on the home's value at sale. Colorado is relatively heir-friendly — there is no state inheritance tax and no separate state estate tax. However, Colorado does tax capital gains as ordinary income at a flat 4.4% state rate, so your net gain from selling an inherited Denver or Colorado Springs property will face both federal and state tax. Consulting a Colorado-based financial advisor or estate planning attorney early helps reduce surprises and keeps your overall tax liability under control.
The Stepped-Up Basis Concept
The IRS resets your cost basis to the home's fair market value at the owner's date of death. This rule can greatly reduce your capital gains tax when you sell an inherited Colorado property.
How the tax basis resets to the property's fair market value at the date of death.
If you inherit property in Colorado, your tax basis resets to the fair market value (FMV) as of the decedent's date of death under Internal Revenue Code Section 1014. For example, if your grandmother bought her Aurora home in 1985 for $60,000 and it was worth $400,000 when she passed in 2023, your new cost basis is $400,000 — not $60,000. This step-up erases much of the capital gains tax on decades of appreciation.
As an heir, you only pay capital gains taxes on increases above this stepped-up basis. If you sell that home for $415,000, your taxable gain is just $15,000. Executors may choose an alternate valuation date up to six months after death using IRS Form 706 if it benefits the estate. A professional appraisal at the time of death is especially important in active markets like Denver, where values can shift quickly.
Example: Grandma bought the house for $60k in 1985, worth $400k at her death in 2023, sold for $415k — you owe tax on $15k, not $355k.
The stepped-up basis shields you from capital gains tax on all past appreciation. The IRS counts as taxable income only the profit above the new stepped-up basis. This rule prevents double taxation and keeps your tax liability far lower than most Colorado heirs fear. Always review IRS Publication 551 or speak with a Colorado CPA for guidance specific to your situation.
Capital Gains Tax Rates

Capital gains tax on inherited Colorado property uses federal rates of 0%, 15%, or 20% based on your taxable income and filing status — plus Colorado's flat 4.4% state income tax on the same gain.
Federal rates: 0%, 15%, or 20% depending on income.
You pay capital gains tax only on profit from selling the inherited property, not the full sale price. For 2024, single filers with taxable income below $47,025 owe 0% federal capital gains tax. The 15% bracket applies up to $518,900 for singles or $583,750 for married couples filing jointly. Above those thresholds, the federal rate is 20%. High earners may also owe an additional 3.8% Net Investment Income Tax if individual income exceeds $200,000 or joint income exceeds $250,000.
On top of federal rates, Colorado taxes your capital gain as ordinary income at a flat 4.4% state rate. So a Colorado heir in the 15% federal bracket effectively pays close to 19.4% combined on their net gain. Use Form 1040 for federal reporting and Colorado Form 104 for your state return.
Inherited property is always treated as long-term.
The IRS always treats inherited property as long-term, regardless of how quickly you sell. Even if you sell a Lakewood home one week after inheriting it, you still qualify for long-term capital gains rates — never the higher short-term rates. This benefit, confirmed in IRS Publication 559, often reduces the financial burden during difficult family transitions.
Primary Residence Exclusion

Why the exclusion typically doesn't apply to inherited homes.
The IRS primary residence exclusion requires that you both own and live in the home as your main residence for at least two of the five years before selling. Most Colorado heirs do not move into an inherited house, so they cannot use the $250,000 (single filer) or $500,000 (married filing jointly) exclusion. Instead, the stepped-up basis provides the main tax protection. 1
Exception: moving in for at least 2 of the past 5 years.
If you inherit a Colorado home and make it your primary residence for at least two out of the five years before selling, you may qualify for the exclusion under 26 U.S. Code Section 121. Keep documentation such as utility bills and tax returns showing your address. Meeting this requirement can eliminate a significant portion of your federal capital gains liability — and reduce your Colorado state income tax on the gain as well.
Estate Taxes vs. Income Taxes

Federal estate tax and Colorado's no-estate-tax environment.
Federal estate tax only applies if the total estate value exceeds $13.61 million per person in 2024 — roughly $27.22 million for married couples. Only about 0.1% of estates nationally owe this tax. Colorado does not impose its own state estate tax or inheritance tax, which puts Colorado heirs in a more favorable position than residents of states like Maryland or New Jersey that have lower state-level thresholds.
Even when no estate tax is owed, large estates may still need to file IRS Form 706. Executors also file Form 8971 and Schedule A to report asset basis to heirs. Accuracy matters — overstating asset basis can trigger IRS penalties under Notice 2016-27. Work with a Colorado probate attorney or CPA to confirm all filing obligations are met correctly.
Colorado-Specific Tax Considerations

No Colorado inheritance tax or state estate tax.
Colorado repealed its state estate tax years ago and has never had a state inheritance tax. This means heirs in Denver, Colorado Springs, Aurora, and throughout the state do not owe Colorado any tax simply for receiving an inheritance. The main Colorado tax concern when selling inherited real estate is the state's 4.4% flat income tax applied to your capital gain.
Colorado capital gains and real estate transfer fees.
Colorado taxes capital gains as ordinary income on your Colorado Form 104 state return at the flat 4.4% rate. There is no separate preferential rate for capital gains at the state level, so your entire net taxable gain is subject to that rate regardless of how long you held the property. Colorado also imposes a real property transfer declaration (TD-1000) at the time of sale, though the documentary fee is modest — $0.01 per $100 of consideration. Some Colorado counties may have additional recording fees. Confirm current requirements with the county assessor's office in the county where the property is located. Work with a Colorado real estate attorney or title company to ensure all transfer requirements are properly handled at closing.
Multiple Heirs and Tax Implications
If you inherit a Colorado home with siblings or other family members, each heir receives their own stepped-up basis proportional to their ownership share. Each person reports their individual share of proceeds and taxable gain on their own federal Form 1040 and Colorado Form 104.
Splitting proceeds and tax obligations.
Divide proceeds based on each heir's ownership percentage. For example, if three siblings inherit a Denver home sold for $415,000 with a stepped-up basis of $400,000, each reports one-third of the $15,000 gain — about $5,000 — on their individual returns. Use Schedule D (Form 1040) and Form 8949 at the federal level. Deduct your share of selling expenses such as agent commissions, title fees, and required repairs before calculating your taxable gain. 2 Disputes among heirs can delay tax filings, so keep all records organized and consult a Colorado probate attorney early in the process.
Deductions You Can Claim
You can reduce your taxable gain by deducting allowable costs tied to the sale. Real estate commissions, title insurance, escrow fees, attorney fees, transfer recording fees, and appraisal costs all reduce your net proceeds before calculating gain. Capital improvements made after inheriting the home — such as a new roof or HVAC system — increase your basis and further lower your taxable gain. Routine repairs do not qualify. Keep all receipts and invoices to support these deductions if the IRS or Colorado Department of Revenue reviews your return.
Timing Considerations
The tax year in which you close the sale determines when you report the gain. If you close a Colorado Springs home sale in December 2024, report the gain on both your 2024 federal return (due April 2025) and your 2024 Colorado Form 104. If you expect a significant gain, consider making estimated tax payments to the IRS and to the Colorado Department of Revenue to avoid underpayment penalties. Colorado requires estimated payments if you expect to owe more than $1,000 in state tax for the year. A Colorado CPA can help you time your sale and plan estimated payments accordingly.
Special Situations
Inherited rental properties and depreciation recapture.
If you inherit a rental property in Colorado, you receive a new stepped-up basis equal to its fair market value at the date of death and begin a fresh depreciation schedule. Any depreciation you claim after inheriting the property becomes subject to depreciation recapture tax at up to 25% under IRS Section 1250 rules when you eventually sell. Keep detailed records of your new basis and all post-inheritance depreciation claimed. IRS Publication 527 covers these rules in detail.
Selling below the stepped-up basis (capital loss).
If you sell an inherited Colorado property for less than its stepped-up basis — possible in a shifting market — you may have a deductible capital loss, but only if the property was used as business or investment property, not as your personal residence. The IRS allows up to $3,000 in capital losses per year against ordinary income, with any excess carrying forward to future years. Report the loss on Schedule D (Form 1040).
Options for Selling Your Inherited Colorado Home
Consider your options before selling. Listing with a Colorado real estate agent works well if the home is in good condition and you want full market value. Cash buyers can accelerate the process — helpful when there are multiple heirs, outstanding liens, or probate timelines creating urgency. Some owners explore donating the property for potential charitable deductions. Whatever path you choose, discuss the tax implications with a Colorado estate planning attorney or CPA before accepting any offer. Getting a professional appraisal early establishes your stepped-up basis and supports accurate reporting.
Conclusion
Selling an inherited home in Colorado involves federal capital gains rules, Colorado's 4.4% flat state income tax on your gain, and the probate process if the estate goes through Colorado's court system. The good news: Colorado has no state inheritance tax or estate tax, and the stepped-up basis rule dramatically limits what most heirs owe. Take these key steps: get a professional appraisal at the date of death, keep all receipts for improvements and selling costs, file both your federal Form 1040 and Colorado Form 104 accurately, and consult a Colorado estate planning attorney or CPA before making final decisions.

FAQs
1. Does Colorado have an inheritance tax or estate tax?
No. Colorado does not impose a state inheritance tax or a state estate tax. Heirs in Colorado only need to consider federal estate tax rules (which apply only to estates over $13.61 million in 2024) and Colorado's 4.4% flat income tax on any capital gain when they sell inherited property.
2. How does Colorado tax capital gains on an inherited home sale?
Colorado taxes capital gains as ordinary income at a flat 4.4% state rate, reported on Colorado Form 104. This is applied to your net taxable gain — the sale price minus your stepped-up basis and allowable deductions — on top of any federal capital gains tax you owe.
3. What is the stepped-up basis and how does it help Colorado heirs?
The stepped-up basis resets your cost basis to the home's fair market value at the date of the original owner's death. This means you only pay tax on appreciation that occurs after you inherit — not on decades of prior growth. In a high-value market like Denver, this rule can save heirs tens of thousands of dollars.
4. Do I need to go through probate in Colorado before selling an inherited house?
It depends on how the property was titled. If the home was solely in the decedent's name without a beneficiary designation or joint tenancy, it likely must pass through Colorado's probate process before you can sell. Colorado has both formal and informal probate procedures. An estate planning attorney familiar with Colorado law can guide you through the appropriate process.
5. Should I consult a professional before selling an inherited Colorado home?
Yes. A Colorado estate planning attorney or CPA can help you navigate probate requirements, confirm your stepped-up basis, plan for estimated tax payments to both the IRS and the Colorado Department of Revenue, and identify all available deductions — minimizing your overall tax liability.
