What Is the Real Estate Transfer Tax and How Much Will You Pay Selling a $1.6M Bay Area Home?
You have built enormous equity in your home over the years, and now you are ready to sell. Before you get to that number in your bank account, there is a line item on the closing statement that surprises almost every seller the first time they see it: the real estate transfer tax.
Here is the short answer. In most of Contra Costa and Alameda counties, the base documentary transfer tax is $1.10 per $1,000 of the sale price, which comes to roughly $1,760 on a $1.6M home. Some cities layer on their own additional transfer tax on top of the county rate, and those city rates can be significantly higher, especially in Oakland and Berkeley, where the tax is tiered and rises sharply above certain price points. Knowing which rate applies to your specific city matters enormously when you are estimating your net proceeds.
I'm Katrina Carter, an East Bay broker and loan officer who specializes in helping longtime homeowners make smart decisions about their equity, and this is one of the first numbers I calculate for anyone thinking about selling a high equity home.
1. What the Transfer Tax Actually Is
The transfer tax is a one time charge collected when property changes hands, based on the sale price. It is separate from property taxes, separate from your agent's commission, and separate from any capital gains you may owe. In California, the county rate is set by state law at $1.10 per $1,000 of value, but individual cities are allowed to add their own tax on top of that county rate, and many East Bay cities do exactly that.
2. Who Actually Pays It
In most of Alameda and Contra Costa counties, this is customarily a seller cost, though it is technically negotiable between buyer and seller in any contract. Lafayette, Danville, Orinda, Moraga, and San Ramon generally follow the county base rate with no significant added city tax, which keeps the cost relatively predictable in those markets.
3. Why Oakland and Berkeley Are Different
Oakland and Berkeley both impose their own additional transfer tax on top of the county rate, and both use a tiered structure where the percentage increases as the sale price climbs. This means a seller in the Oakland Hills at $1.6M or above can pay a meaningfully higher combined transfer tax than a seller in Lafayette or Danville at the same price point. If you own in Oakland or Berkeley and are getting close to a decision to sell, this is one of the first numbers I calculate, because it changes your net proceeds by thousands of dollars compared to a similarly priced home just a few miles away.
4. How This Interacts With Prop 19 and Your Overall Equity Picture
Buyers who come to me often say they wish they had known to look at total transaction costs, not just commission, when they first started thinking about selling. Transfer tax stacks on top of commission, escrow fees, and any capital gains exposure above the $500,000 exclusion for married couples. For a longtime homeowner with decades of appreciation, the full picture of what actually lands in your account after a sale can look quite different from the sale price alone.
5. How to Estimate Your Number Before You Decide Anything
In my experience helping families with this decision, the smartest first step is not deciding whether to sell, it is simply calculating what selling would actually net you today. That means starting with your estimated sale price, subtracting commission, subtracting the correct transfer tax for your specific city, subtracting any remaining mortgage balance, and then looking at capital gains exposure separately. Only once you have that real number can you compare it honestly to the alternative of holding the property.
6. Why This Matters More the Higher Your Home's Value
The transfer tax is calculated as a percentage of sale price, so the dollar impact grows directly with your home's value. On a $900,000 home the county base tax is under $1,000. On a $2.5M home in a city with an added tax tier, the combined transfer tax can run into the tens of thousands of dollars. This is exactly the kind of number that belongs in a conversation with your CPA well before you list, not something you discover on your closing statement.
FAQ
Is the transfer tax the same everywhere in the Bay Area?
No. The county base rate is consistent, but individual cities can and do add their own tax on top of it, and those added rates vary significantly by city.
Can transfer tax be negotiated between buyer and seller?
Yes, in theory. In practice, local custom in most Alameda and Contra Costa communities has the seller paying it, though this can be negotiated as part of the purchase agreement.
Does transfer tax apply to inherited property?
Certain transfers, including some inherited property transactions, may qualify for exemptions. This is a conversation to have with your title company and your estate planning attorney before assuming a rate applies.
How do I find the exact rate for my city?
Your title company or escrow officer can confirm the exact combined county and city rate before you list, and I calculate this for every seller I work with as part of preparing a realistic net sheet.
If you are a longtime homeowner in the East Bay thinking about what selling would actually put in your pocket, I would be glad to run your specific numbers, including the transfer tax for your exact city, before you decide anything.
