EAST BAY HOME SELLERS | TAX GUIDE
What Happens to Your Taxes When You Sell?
A plain-English breakdown of capital gains tax for East Bay homeowners selling their primary home or a rental property.
Whether you are selling a longtime home in Walnut Creek, a condo in Concord, or a rental in Hercules, the tax picture matters just as much as the sale price. Here is what you need to know before you sign.
Selling Your Primary Home
When you sell the home you live in, the IRS gives you a significant break under Section 121 of the tax code. You can exclude a portion of your profit from federal capital gains tax entirely, as long as you qualify.
The Exclusion
$250,000
Excluded from tax
Single filers
$500,000
Excluded from tax
Married, filing jointly
What this means in practice: If you bought your Pleasant Hill home for $450,000 and sell for $800,000, your gain is $350,000. As a married couple, the first $500,000 is excluded, so you owe nothing in federal capital gains tax on that sale.
To qualify, you must have owned and lived in the home as your primary residence for at least 2 of the past 5 years. You can only use this exclusion once every two years. The two years do not need to be consecutive.
What If Your Gain Exceeds the Exclusion?
East Bay values have risen sharply. Long-term homeowners in Danville or San Ramon in particular may have gains well above the $500,000 threshold. Any profit above the exclusion amount is subject to capital gains tax.
What Is Capital Gains Tax and Who Collects It?
A capital gain is the profit you make when you sell an asset for more than you paid. Your home is a capital asset. When your gain exceeds your exclusion, the IRS taxes the remainder. The federal government collects this tax through the IRS. The rate depends on how long you owned the home and your income level.

High earners
California does not offer preferential capital gains rates. The state taxes all capital gains as ordinary income, at rates from 1% up to 13.3%. California follows the federal Section 121 exclusion, so the excluded amount is not taxed at the state level. But anything above the exclusion gets hit at your full state income tax rate.
Selling a Rental or Investment Property
Selling a second home, rental, or investment property is a different situation entirely. The Section 121 exclusion does not apply. Every dollar of profit is taxable, and the tax picture is more complex.
Who Collects the Tax?
Both the IRS (federal) and the California Franchise Tax Board (state) want their share. There is no exclusion available, and California treats the entire gain as ordinary income regardless of how long you held the property.
Depreciation Recapture: The Hidden Bill
If you owned a rental property, you likely took annual depreciation deductions to reduce your taxable rental income. That was valuable while you held the property. But when you sell, the IRS requires you to pay tax on the depreciation you claimed. This is called depreciation recapture.
Example:
You claimed $80,000 in depreciation on your Concord rental over 10 years. When you sell, that $80,000 is added back to your taxable gain. Federally, it is taxed at a flat 25%. California taxes it as ordinary income at your marginal rate, which could be as high as 13.3%. That is a combined bill of up to 38% on just the recaptured depreciation, before you count the appreciation gain.
On top of recapture, the remaining appreciation gain is taxed at federal long-term capital gains rates (0% to 20%) and at California ordinary income rates (up to 13.3%). High-income sellers may also owe a 3.8% federal Net Investment Income Tax.
Tips for Sellers
1. Track your cost basis carefully. Your taxable gain is calculated from your adjusted cost basis, not just your purchase price. Capital improvements (kitchen remodel, new roof, ADU addition) increase your basis and reduce your taxable gain. Keep every receipt.
2. Time your sale around income. If you expect lower income in a given year, selling then can push you into a lower capital gains bracket and reduce your federal bill.
3. Consider a 1031 exchange for rental properties. If you are selling an investment property and plan to buy another, a 1031 exchange lets you defer capital gains taxes by rolling the proceeds into a replacement property. Note: California tracks 1031 exchanges and can clawback deferred gains if you eventually sell the replacement property outside California.
4. Do not forget selling costs. Commissions, title fees, transfer taxes, and staging costs can all be deducted from your gain, reducing your taxable profit.
5. Talk to a CPA before you list. Tax strategy before the sale gives you options. Once escrow closes, your choices are gone. A good CPA who knows California real estate can make a meaningful difference in your net proceeds.
6. Converting a rental to a primary residence has limits. Even if you move into a former rental and eventually claim the Section 121 exclusion, depreciation taken during the rental period must still be recaptured. Plan carefully.
The Bottom Line
Most East Bay homeowners selling a primary residence will walk away with a very manageable tax bill, especially with the Section 121 exclusion. Rental property sales require more planning. Either way, knowing the rules before you sell puts you in a stronger position at the closing table.
