## How Capital Gains Tax Works on an Inherited House Sale When you sell a house that you inherited, the IRS treats the transaction differently than a standard home sale. The property receives a step-up in cost basis to its fair market value on the date of the original owner's death. This means the taxable gain is calculated from that stepped-up value, not from the original purchase price the deceased paid decades earlier. For most heirs, this step-up eliminates a large portion of potential capital gains that would otherwise apply if the property had been gifted during the parent's lifetime.
The federal long-term capital gains tax rate for inherited property is 0%, 15%, or 20% depending on the seller's taxable income. In 2026, single filers with taxable income below $47,025 pay 0%, those between $47,025 and $518,900 pay 15%, and those above $518,900 pay 20%. Married couples filing jointly have thresholds of $94,050 and $1,037,800 respectively. These rates apply to the gain realized above the stepped-up basis, which for many inherited homes results in little to no federal tax liability.

The sale must also clear the IRS ownership and use tests if the seller wishes to exclude up to $250,000 of gain ($500,000 for married couples). However, inherited property does not receive the $250,000 primary residence exclusion in the same way a personally purchased home does. The step-up in basis already provides a substantial tax shield, making the exclusion less relevant for most inherited home sales. The IRS has been increasing scrutiny of inherited property sales in 2026, particularly when heirs sell within months of the original owner's passing.
## The Step-Up in Basis: Why It Matters for Inherited Homes The step-up in basis is the single most important tax concept for anyone selling an inherited house. When a person dies, the Internal Revenue Service resets the cost basis of their assets to the fair market value at the date of death. For a house purchased in 1980 for $80,000 that is now worth $650,000 at the time of the owner's death in 2026, the heir's new cost basis becomes $650,000. If the heir sells the property for $680,000, the taxable gain is only $30,000 rather than the $600,000 gain that would apply if the original owner had sold it themselves.
This step-up applies to all inherited property, including real estate, investment accounts, and personal property. The IRS requires the executor of the estate to file Form 706 if the estate exceeds the federal exemption threshold, which was $13.61 million per individual in 2024 and is adjusted for inflation annually. For most middle-class families, the estate will not trigger federal estate tax, but the step-up in basis still applies to the inherited property regardless of estate tax liability.
The step-up rules have faced political pressure in Washington. Proposals to limit or eliminate the step-up have appeared in various budget frameworks, but as of August 2026 the rules remain intact for inherited real estate. The Niskanen Center has advocated for changes to the tax code that would affect family-sized housing markets, but no legislation has yet altered the step-up in basis for inherited homes. Heirs should plan their sale timing carefully, as future Congresses could change these rules.
## State Capital Gains and Inheritance Taxes on Inherited Property Beyond federal taxes, state-level taxes on inherited property vary dramatically. Six states impose an inheritance tax as of 2026: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Rates and exemptions differ by state, with surviving spouses typically exempt and children and grandchildren receiving reduced rates. In Pennsylvania, for example, direct descendants pay 4.5% on inherited property, while siblings pay 12% and unrelated beneficiaries pay 15%.
California does not impose an inheritance tax or a state-level capital gains tax on inherited property beyond the federal rules. However, the San Francisco Chronicle has reported that the math on inheriting a home in California has changed in recent years due to Proposition 19, which took effect in 2021. Prop 19 limited the ability of parents to transfer property tax bases to children when the property is not the primary residence, though this affects property taxes rather than capital gains taxes directly.
New York State imposes its own capital gains tax on inherited property, with rates ranging from 4% to 10.9% depending on income. Washington State levies a capital gains tax of 7% on profits from the sale of inherited real estate above $250,000 for individuals. Oregon has a top capital gains rate of 9.9% on gains exceeding $250,000 for single filers. Heirs should consult a state-specific tax professional to understand their combined federal and state obligations before listing the property.
## Practical Steps for Selling an Inherited House in 2026 The first step after inheriting a house is to obtain a professional appraisal to establish the fair market value on the date of death. This appraisal becomes the foundation for the stepped-up cost basis and will be essential documentation if the IRS audits the sale. The IRS has intensified its review of inherited property sales in 2026, particularly those where the property is sold quickly after the original owner's death or where the reported gain seems inconsistent with local market conditions.
Next, the heir should determine whether the property qualifies for any exclusions or deferrals. If the heir lived in the inherited home as their primary residence for at least two of the five years preceding the sale, they may claim the $250,000 or $500,000 gain exclusion in addition to the step-up in basis. This combination can eliminate federal capital gains tax entirely on gains up to those thresholds. The heir must file Form 8949 with their federal tax return to report the sale and calculate the gain based on the stepped-up basis.
Timing the sale matters for both tax and financial reasons. Selling within one year of inheriting may trigger short-term capital gains treatment if the property was not held for the required period, though the step-up in basis typically makes this a non-issue for inherited property. Heirs should also consider the impact of capital improvements made before the sale, as these can further reduce the taxable gain. Keeping detailed records of all improvements, repairs, and selling costs ensures the lowest possible tax bill.
## Common Mistakes When Selling an Inherited House One of the most frequent errors is failing to use the stepped-up cost basis and instead using the original purchase price from the deceased's records. This mistake can result in a dramatically overstated gain and a tax bill that is thousands of dollars higher than necessary. The IRS expects executors and heirs to obtain a date-of-death valuation, and failing to do so can trigger an audit or a penalty assessment.
Another common mistake is assuming the $250,000 primary residence exclusion applies automatically to inherited homes. The exclusion requires the seller to have lived in the property as their primary residence for at least two of the five years before the sale. Many heirs sell inherited properties quickly without ever living in them, which means they cannot claim this exclusion. While the step-up in basis often makes the exclusion unnecessary, it is important to understand the distinction.
Heirs also overlook state-specific filing requirements. In states like Maryland and New Jersey, inherited property sales may trigger both inheritance tax and capital gains tax obligations that must be reported separately. Failing to file the correct state forms can result in penalties and interest charges. Additionally, some heirs attempt to sell the property without clearing title issues, which can delay the transaction and create legal complications that increase the overall cost of the sale.
## When to Sell and When to Hold an Inherited Property The decision to sell or hold an inherited house depends on financial goals, market conditions, and tax planning. If the property is in a strong seller's market with rising values, selling quickly after probate closes can lock in gains before the market shifts. The step-up in basis means that even a modest sale price above the date-of-death value generates taxable income, so timing the sale to coincide with a year of lower personal income can reduce the capital gains tax rate.
Holding the property makes sense when the heir intends to rent it out or use it as a future residence. Rental income generates taxable income, but expenses such as mortgage interest, property taxes, repairs, and depreciation can offset the gains. If the heir plans to move into the inherited home and live there for at least two years before selling, the combination of the step-up in basis and the primary residence exclusion can eliminate federal capital gains tax entirely on gains up to $500,000 for a married couple.
The IRS audit focus on inherited property sales in 2026 means that heirs should document every decision carefully. If the property requires significant repairs before it can be sold, the heir should budget for those costs and retain receipts. Selling an inherited house is not a race, and rushing the process without proper planning can result in unnecessary tax payments or legal disputes among co-heirs.
## Cost and Pricing Considerations for Inherited Home Sales The direct cost of selling an inherited house includes real estate agent commissions, typically 5% to 6% of the sale price, closing costs averaging 2% to 3%, and any capital gains tax owed on the profit. For a house sold at $500,000 with a stepped-up basis of $450,000, the taxable gain is $50,000. At the 15% federal rate, the capital gains tax would be $7,500, plus any state tax owed. Total transaction costs including commissions, closing, and taxes could reach $35,000 to $40,000.
Alternative selling methods such as cash buyers, for-sale-by-owner listings, and auction platforms can reduce commission costs but may result in a lower sale price. Heirs should weigh the savings on commissions against the potential loss in sale price when choosing a selling method. The IRS requires the reported sale price to reflect fair market value, so underpricing the property to avoid taxes is not a viable strategy and can trigger an audit.
Property tax reassessment is another cost consideration that varies by state and county. In some jurisdictions, transferring an inherited property triggers a reassessment of property taxes to current market values, which can increase annual tax bills significantly. California's Prop 19 rules limit the parent-child exclusion for property tax purposes, meaning that inherited rental or investment properties may face reassessment. Heirs should research local property tax rules before deciding whether to sell or hold.

Can I avoid capital gains tax on an inherited house by living in it? Living in the inherited house as your primary residence for at least two of the five years before the sale allows you to claim the $250,000 or $500,000 gain exclusion. Combined with the step-up in basis, this can eliminate federal capital gains tax entirely on gains up to those thresholds. However, the exclusion does not apply if you sell the property within two years of inheriting it without meeting the residency requirement.
What happens if multiple heirs inherit a house and one wants to sell? All co-owners must agree to the sale unless one party petitions a court for partition action. Each heir's share of the gain is calculated based on their percentage of ownership and the stepped-up basis. If the property was inherited by three siblings equally, each reports one-third of the gain on their individual tax return. Disputes among heirs can delay the sale and increase legal costs.
Is there a capital gains tax exemption for selling an inherited property in 2026? There is no specific exemption that eliminates capital gains tax on inherited property sales. The step-up in basis and the primary residence exclusion are the primary tax advantages available. Some states offer additional exemptions for surviving spouses or family farms, but these vary by jurisdiction. Heirs should consult a tax professional to identify any state-specific exemptions that may apply to their situation.
What documentation do I need to prove the stepped-up cost basis? The primary document is a qualified appraisal conducted near the date of death. The IRS accepts appraisals from certified appraisers who follow Uniform Standards of Professional Appraisal Practice. If no appraisal was obtained, the IRS may accept alternative documentation such as a broker's price opinion or comparable sales data from the same period. Retaining all documentation for at least three years after filing is essential in case of an audit.
