Inheriting a house is rarely simple, and the tax questions come fast. In Los Angeles County, where the median sale price for a home in Hawthorne, CA sits at around $864,000, what you've inherited isn't a sentimental object - it's a substantial financial asset. What you do with it matters. A probate real estate agent in Hawthorne, CA can help you prepare the property for sale, but understanding the tax rules comes first.
Keeping it, renting it, or selling it each carries different tax consequences under federal and California state law. The fear most heirs walk in with is that selling a house the family bought decades ago will trigger a tax bill based on that original price. That fear, fortunately, is misplaced. The rules are built to protect you from exactly that scenario.
How Capital Gains Tax Applies to Inherited Homes
Federal tax law treats inherited property differently than a house you purchased yourself. When a homeowner dies, the IRS resets the property's tax value to its fair market value on the date of death - not what the deceased originally paid for it. That single rule changes everything.
If you sell the inherited house, you only owe capital gains tax on appreciation that occurs between the date of death and the date you close. Whatever gain built up during the original owner's lifetime? Gone, for tax purposes.
How the Step-Up in Basis Rule Works
The tax code calls this reset a step-up in basis. Your basis is the starting number used to calculate your taxable profit, and by stepping it up to the date-of-death value, the IRS effectively erases all the gain that accumulated while the deceased owner held the property.
Say a relative bought a Hawthorne house in 1980 for $80,000 and it was worth $850,000 when they passed away. Your new basis is $850,000. That $770,000 in appreciation that built up over four-plus decades? You're not on the hook for any of it.
Why the Original Purchase Price Drops Out
Once the step-up is applied, the original purchase price is simply irrelevant. You don't need to dig up old closing documents or reconstruct what the deceased paid at settlement. None of that affects your tax calculation.
The only number that sets your starting point is the date-of-death valuation. Any gain or loss is measured strictly against that updated baseline.
Calculating Your Potential Tax Liability
The formula is straightforward: take the final sale price, subtract your stepped-up basis and your sale costs, and what's left is your taxable capital gain.
Worth keeping in mind - homes in Hawthorne currently spend roughly 49 days on the market, so there can be some movement in value between the date of death and the date of sale. Getting the numbers right means you won't overpay the IRS.
Pinpointing the Fair Market Value
You'll need a professional appraisal to establish the date-of-death fair market value. Specifically, you hire a licensed appraiser to evaluate the property as of the day the original owner passed away - this is called a historical or retrospective appraisal.
That appraisal is the documented baseline you'll use on your tax returns. An automated online estimate or a recent property tax bill won't satisfy IRS requirements.
Deducting Sale Costs and Improvements
Before you land on your final taxable gain, you can deduct the costs of selling. Agent commissions, escrow fees, transfer taxes, necessary legal fees - all of it counts.
Capital improvements you made to prepare the house for sale can also be added to your basis. Replacing a roof or updating the electrical system qualifies. Routine maintenance and minor cosmetic touch-ups don't.
A Worked Example for a Hawthorne Sale
For illustration only: you inherit a home in Hawthorne with a date-of-death appraised value of $860,000. Six months later you sell it for $890,000 - a gross profit of $30,000 before deductions.
If you pay $60,000 in agent commissions and closing costs, you're looking at a $30,000 net loss on paper. Zero capital gains tax owed, because the sale costs more than wiped out the post-death appreciation.
California Inheritance and State Taxes
California doesn't have a state-level inheritance tax. The state abolished it decades ago, so you don't owe California anything simply for receiving the asset.
What you're subject to instead is federal estate tax - and that affects very few people. For 2026, it only kicks in on estates exceeding $15,000,000 per individual, or $30,000,000 for married couples using portability.
California Capital Gains Rates for 2026
No inheritance tax doesn't mean no state tax exposure at all. If you sell the property for a profit, California taxes that gain - and unlike the federal government, California doesn't offer a preferential lower rate for long-term capital gains. The state taxes all capital gains as ordinary income under its progressive brackets.
For 2026, those state rates run from 1% up to 13.3%. That top figure includes a 12.3% marginal rate plus an additional 1% Mental Health Services Tax on taxable income over $1,000,000. And this is on top of whatever federal capital gains taxes you owe.
Ways to Limit Your Tax Liability
You have real options here. Timing the sale, changing how you use the property, or simply moving in can drastically alter what you owe - or eliminate the liability entirely. The right path depends on your circumstances, and a licensed tax professional in Los Angeles County is the right person to help you map it out.
Selling Immediately After Inheritance
This is the simplest approach. Because the stepped-up basis matches the home's value at the time of death, a quick sale typically means the property hasn't had time to appreciate further. If the sale price matches the date-of-death appraised value, your capital gain is zero. Once you factor in closing costs and agent commissions, you often end up with a capital loss - which shelters the sale from taxes entirely.
Moving In for the Primary Residence Exclusion
If you move into the inherited home, you can eventually qualify for the Section 121 primary residence exclusion. Single filers can exclude up to $250,000 in capital gains from taxable income; married couples can exclude up to $500,000. To qualify, the home must be your primary residence and you must live there for at least two of the five years before you sell.
This strategy makes the most sense if you're planning to keep the house long-term and expect the value to climb.
Converting the Home to an Investment Property
Renting the property turns it into an income-producing asset. You'll owe taxes on the rental income, but you defer capital gains taxes on the property itself until you sell. When that day comes, a 1031 exchange lets you roll the proceeds into a new investment property - pushing the capital gains tax further down the road, as long as you follow the timelines and rules governing 1031 exchanges.
Handling a Probate Sale in Hawthorne
Selling through the Los Angeles County Probate Court isn't like a standard real estate transaction. There are specific legal timelines and disclosure requirements, and the executor or administrator needs to either secure court approval or use the Independent Administration of Estates Act to list the property.
A local agent with genuine probate experience knows how to market the home correctly while staying within what the court requires. That agent will coordinate with your estate attorney on the paperwork, clear title, and move the transaction toward a clean close - without surprises that drag the timeline out.
Frequently Asked Questions
Do I have to pay capital gains tax when I sell an inherited house in California?
It depends on whether the house appreciated after you inherited it. Because of the step-up in basis, you don't owe capital gains tax on value that built up during the deceased owner's lifetime. You only owe tax on profit above the date-of-death value when you finalize the sale.
What is a step-up in basis for inherited real estate?
It's a tax provision that resets the property's baseline value to its fair market value on the date the original owner died. That wipes out all prior appreciation for tax purposes. When you sell, your taxable gain is calculated from this new stepped-up value - not the original purchase price.
Can I avoid capital gains tax if I live in the inherited house?
Yes. If you make the home your primary residence and live there for at least two of the five years before selling, you can exclude up to $250,000 of capital gains if you're single, or $500,000 if you're married filing jointly.
How do I determine the date-of-death fair market value for a house in Hawthorne to accurately calculate my taxes?
Hire a licensed appraiser to conduct a historical appraisal. This assessment establishes exactly what the home was worth on the day the original owner passed away and gives you the documentation the IRS requires.
If the Hawthorne real estate market goes up while the house is in probate, will I owe taxes on that increase when I sell?
Yes - capital gains tax applies to the increase in value that occurs between the date of death and the date of sale. That said, you can deduct agent commissions, transfer taxes, and closing costs from the final sale price, which frequently offsets minor market gains.
