Step-Up in Basis for Inherited Property: How It Saves You Money in Washington
If you have inherited a home or other property in Washington State, 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 guide explains how this federal tax benefit works, why it matters for capital gains taxes, and how Washington's unique tax environment affects inherited real estate. 1
Key Takeaways
- The step-up in basis resets the property's tax value to its fair market price on the date of death. If you inherit a Seattle home worth $800,000 that your parent bought for $100,000, your cost basis becomes $800,000.
- This rule can save you tens of thousands in capital gains taxes when selling inherited property.
- Washington is a community property state, meaning surviving spouses can receive a full step-up on both halves of jointly owned property.
- Washington has no state income tax, but does impose a capital gains tax on gains above $262,000 (2024 threshold). Inherited property sold near fair market value may fall below this threshold entirely.
- You must report sales using IRS Schedule D and Form 8949. Use certified appraisals to document fair market value at inheritance.
- Only inherited property receives a step-up in basis; gifted assets keep the original owner's cost basis, which can result in much higher capital gains taxes.
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 potential capital gains tax if you sell the property later — especially important in high-value markets like Seattle, Bellevue, and Tacoma.
Definition of "basis" and how step-up resets value
Your "basis" in property is generally what you paid for it, plus costs like major improvements or closing fees. The IRS uses this number to calculate any capital gains tax if you sell.
Under Section 1014 of the Internal Revenue Code, when you inherit real estate, the fair market value on the date of death becomes your new cost basis. Instead of using what your loved one paid decades earlier, you start fresh with the current market value. If an inherited Bellevue home is worth $900,000 at the time of death and you sell it near that price, there may be little or no taxable gain.
This step-up eliminates income taxes on all appreciation that occurred during the deceased's ownership, as detailed in IRS Publication 551.
Example: Parent's home purchase and inheritance scenario
Angela bought her Seattle home in 1980 for $75,000. By the time she passed away in 2020, the home's fair market value had grown to $700,000. As her daughter, you inherited the house with a new cost basis of $700,000 due to the step-up rule.
You sell the home two years later for $725,000. Your taxable gain is only $25,000 rather than $650,000. At federal long-term capital gains rates, the savings are substantial. Washington's 7% capital gains tax would not apply here because your gain falls well below the $262,000 annual threshold.
This illustrates how understanding the step-up rule protects Washington families from enormous tax burdens during already difficult transitions.
How Step-Up Works
The step-up in basis resets the tax basis of inherited real estate to its current fair market value, often reducing your capital gains tax if you sell. Washington's tax rules add an important layer to this federal benefit.
Valuation process and inheritance rules
- Executors must establish the fair market value (FMV) of the property as of the date of death, typically using a certified independent appraisal or comparable sales in the local market.
- An alternate valuation date — six months after death — may be used if property values have declined, potentially reducing future capital gains taxes.
- The cost basis for inherited property equals its FMV at the date of death or the alternate valuation date, not the original purchase price.
- Required documentation includes a certified appraisal, the death certificate, deeds, closing statements, and records of any improvements made by the deceased.
- Only inherited property receives a step-up in basis. Gifts made during the owner's lifetime use carryover basis, which can result in significantly higher capital gains taxes later.
- Report the sale on IRS Schedule D and Form 8949. A Washington-licensed CPA or estate attorney can help ensure accuracy and compliance with both federal and state requirements.
- If the executor filed a federal estate tax return and issued Schedule A to Form 8971, heirs must use the value reported there 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 Tacoma rental property for $120,000 and it is worth $550,000 when you inherit it, your new tax basis is $550,000. You only owe capital gains tax on any increase above that value when you sell.
Gifted assets keep the original owner's cost basis. If someone gifts you real estate during their lifetime, you take on their original purchase price. All past appreciation becomes taxable under your name when you sell. In Washington, this matters even more because gains above the $262,000 annual threshold are subject to Washington's 7% capital gains tax in addition to federal rates. 1
Careful estate planning — including community property trusts or revocable living trusts — can help Washington families maximize the step-up benefit and minimize overall tax exposure.
Step-Up in Basis for Married Couples in Washington
Washington is a community property state, which gives married couples a significant tax advantage when one spouse passes away. This can result in a full step-up in basis on jointly owned property.
Full step-up in Washington as a community property state
Because Washington is a community property state, surviving spouses receive a full step-up in basis on both halves of community property after a spouse dies. This means the entire fair market value of the property is reset on the date of death — not just the deceased spouse's share.
For example, if you and your spouse purchased a Spokane home for $300,000 and it is worth $600,000 when your spouse passes, your new cost basis becomes the full $600,000. All appreciation during the marriage is essentially wiped out for tax purposes. This can eliminate capital gains taxes entirely if you sell at or near the stepped-up value.
To qualify, assets must have been acquired during the marriage as community property. Inherited or gifted property held separately generally does not qualify. Working with a Washington estate planning attorney is strongly recommended to confirm how your specific assets are titled.
Joint tenancy and other ownership structures
If Washington property is held as joint tenancy with right of survivorship rather than community property, only the deceased spouse's half receives a step-up in basis. The surviving spouse's half retains the original cost basis. This partial step-up can result in a higher taxable gain when the property is eventually sold.
For this reason, many Washington couples work with estate attorneys to retitle property as community property or place it in a community property trust to secure the full step-up benefit. If you are unsure how your property is titled, review your deed or consult a Washington real estate attorney before making any decisions.
Selling Inherited Property in Washington
Selling inherited real estate in Washington often results in lower capital gains taxes because of the step-up in basis rules. Understanding both federal and Washington state tax implications will help you make the right decision.
Long-term capital gains treatment and Washington's capital gains tax
Inherited property automatically qualifies for long-term capital gains treatment at the federal level, regardless of how long you or the deceased held the asset. Federal long-term rates for 2025 are 0%, 15%, or 20% depending on your income bracket.
Washington enacted a 7% capital gains tax that applies to gains exceeding $262,000 per year (2024 threshold, adjusted annually for inflation). Importantly, the sale of real estate is currently exempt from Washington's capital gains tax — only certain assets like stocks and bonds are subject to it. This means most inherited home sales in Washington are only subject to federal capital gains tax, not the state capital gains tax.
However, if the estate includes investment accounts, mutual funds, or other non-real estate assets, Washington's capital gains tax may apply to gains above the threshold. Consult a Washington CPA to understand how your specific inherited assets are treated.
Considerations for selling quickly or holding
Selling inherited property shortly after probate often minimizes capital gains tax. If you sell within 6 to 12 months, the step-up in basis means the sale price will typically be close to your new cost basis, leaving little or no taxable gain. 3
Holding inherited real estate comes with ongoing costs: property taxes, insurance, and maintenance can easily run $1,000 to $3,000 per month in the Seattle or Bellevue markets. Out-of-area heirs often find it difficult to manage these expenses from a distance. Renting the property before selling may also trigger depreciation recapture, increasing your federal tax liability later.
When multiple heirs are involved, disagreements over selling versus holding can further complicate and delay decisions. Weighing emotional ties against practical financial realities — ongoing costs, potential appreciation, and tax exposure — is essential.
Tax Reporting for Inherited Property Sales
Selling inherited property requires careful tax reporting at both the federal level and, for certain assets, the Washington state level. Working with a CPA familiar with Washington tax law is highly recommended.
Required forms and professional help
- Report the sale of inherited property on IRS Schedule D (Form 1040) and Form 8949 if you have a taxable gain.
- Use the fair market value at the date of death or alternate valuation date as your new basis.
- If the executor filed a federal estate tax return with Schedule A to Form 8971, you must use the value reported there as your basis.
- Washington has no state income tax, so there is no state income tax return to file for real estate sale proceeds. However, if non-real estate inherited assets generate gains above $262,000, Washington's capital gains tax may apply and requires a Washington state capital gains tax return.
- Review IRS Publications 550 and 559 for guidance on inherited assets, estate administration, and reporting requirements.
- Consult a Washington-licensed estate attorney or CPA, particularly for estates involving community property trusts, irrevocable trusts, or investment accounts subject to Washington's capital gains tax.
Professional guidance reduces the risk of errors, missed deductions, and IRS accuracy-related penalties — all of which can be costly when dealing with high-value Washington real estate.
Insights and Considerations for Inherited Houses in Washington
Inherited houses in Washington often come with unexpected challenges. Many older homes require significant repairs before going to market. In competitive markets like Seattle and Tacoma, property taxes, insurance, and maintenance costs can run $1,500 to $3,500 per month while you hold the property.
Disagreements among heirs can delay decisions and increase carrying costs. Confusion about the step-up in basis rule sometimes leads to unnecessary fear of large tax bills — in many cases, heirs owe little or nothing if they sell near the inherited value.
Washington's community property rules can provide powerful tax advantages for surviving spouses, but only if the property is properly titled. An accurate certified appraisal at the time of inheritance is essential documentation for both federal estate purposes and any Washington state reporting obligations.
For heirs who want to avoid the stress and cost of a traditional sale, selling quickly for cash can eliminate months of carrying costs, repair expenses, and uncertainty. Donating appreciated non-real estate assets to charity is another strategy that avoids capital gains taxes while providing an income tax deduction.
Conclusion
The step-up in basis offers real, significant savings for Washington heirs. By resetting the property's cost basis to fair market value at the date of death, you can often avoid substantial capital gains taxes. Washington's community property rules make this benefit even stronger for surviving spouses. Washington's exemption of real estate from the state capital gains tax adds another layer of protection for most home sales.

FAQs
1. What does step-up in basis mean for inherited property in Washington?
Step-up in basis raises the tax basis of inherited real estate to its fair market value on the date of death. This new cost basis reduces your taxable gain if you sell the property, and in Washington, most home sales are also exempt from the state capital gains tax.
2. Does Washington's capital gains tax apply to inherited real estate?
Generally, no. Washington's 7% capital gains tax currently exempts real estate sales. However, if the inherited estate includes stocks, mutual funds, or other investment assets with gains above the annual threshold (approximately $262,000 in 2024), those gains may be subject to Washington's capital gains tax.
3. How does community property status affect the step-up in Washington?
Because Washington is a community property state, surviving spouses typically receive a full step-up in basis on both halves of jointly owned property when one spouse dies. This can eliminate capital gains taxes on all appreciation that occurred during the marriage.
4. Can using an alternate valuation date help reduce taxes?
Yes. If property values have declined after the date of death, the estate may use an alternate valuation date six months later. This can lower the reported estate value and potentially reduce future capital gains taxes when the property is sold.
5. Should I sell inherited property quickly or hold it?
Selling soon after probate generally minimizes tax exposure because the sale price will be close to the stepped-up basis. Holding the property increases carrying costs and may trigger additional tax issues like depreciation recapture if you rent it out.
6. Where can I get help managing an inherited property in Washington?
A Washington-licensed estate attorney or CPA can guide you through the legal and tax requirements. If you want to sell quickly without repairs or commissions, KDS Homebuyers offers a free cash offer at kdshomebuyers.net.
