San Francisco Seller Closing Costs and Transfer Tax

A house that sells for $4,999,999 in San Francisco owes the city roughly $37,500 in transfer tax. Raise the price by one dollar, to an even $5,000,000, and the bill jumps to roughly $112,500. That is not a typo and it is not a rounding quirk. It is $75,000 in tax triggered by a single dollar of sale price, and it is the reason a surprising number of San Francisco listings in the $5 million range top out at $4.95 million or $4.999 million instead of drifting a little higher.

Most sellers never learn this until an escrow officer walks them through the net sheet. By then the list price is already set, the offers are already in, and the math is already locked. Understanding the mechanism before you price a home, not after, is the difference between a strategy and a surprise.

The Line at $5,000,000

San Francisco's real property transfer tax does not work the way most people assume a tiered tax works. With income tax, you only pay the higher rate on the income above each threshold. San Francisco's transfer tax applies the tier rate to the entire sale price once you cross the line. There is no marginal cushion.

Below $1 million, the rate is small enough that this quirk barely registers. Between $1 million and $4,999,999, San Francisco taxes the full sale price at 0.75 percent. The moment a sale touches $5,000,000, the rate on the entire price jumps to 2.25 percent. A seller comparing a price of $4.999 million against $5.1 million needs to see the real math: the extra $100,000 in sale price triggers about $77,000 in additional transfer tax alone, because the higher rate applies to the whole price, not just the slice above the line. The net gain from pushing the price higher shrinks to roughly $23,000, before anyone even asks whether the market treats a home priced above $5 million differently than one priced just under it.

This is the transfer tax that the San Francisco Office of the Assessor-Recorder collects at the time a deed is recorded, and it is customarily paid out of the seller's proceeds.

The Full Schedule

The jump between the third and fourth rows is the one that reshapes pricing conversations across the city's upper-middle market, from Noe Valley to Russian Hill to parts of Pacific Heights where $5 million has become close to an entry price for a nicer single-family home.

A Second, Bigger Cliff at $10 Million

The $5 million line gets most of the attention because it touches more transactions, but the steeper cliff sits at $10 million. A sale at $9,999,999 is taxed at 2.25 percent, or about $225,000. Cross to $10,000,000 and the rate more than doubles to 5.5 percent, pushing the tax to roughly $550,000. That is a $325,000 swing triggered by one dollar of price, more than four times the size of the jump at the $5 million line.

This tier exists because of Proposition I, which San Francisco voters approved in November 2020 and which doubled the transfer tax rate on sales of $10 million or more. Before Prop I, a sale in that range was taxed closer to 2.75 percent. After, it became 5.5 percent, with the rate on sales of $25 million or more climbing to 6 percent, according to the text of the ordinance now on file with the Board of Supervisors.

Why the Rate Is Frozen Right Now

If you have read about San Francisco's transfer tax anywhere else recently, you may have come across mention of a rollback. In February 2026, Mayor Daniel Lurie and District 5 Supervisor Bilal Mahmood introduced legislation known as the BUILD Act, which proposed cutting the rate on sales above $10 million roughly in half, back toward pre-2020 levels, to help stalled housing projects pencil out again.

That plan is currently on ice. In June 2026, Mahmood confirmed the city was stepping back from the cut, tying the decision directly to San Francisco's budget picture.

"Until that is resolved we are not proceeding."

That quote, reported by The Real Deal in June 2026, matters more than it might seem. It means the higher, post-Prop I rates on the $10 million and $25 million tiers remain in effect today, in August 2026, with no confirmed date for reconsideration. Sellers weighing whether to wait out a friendlier tax environment before listing a high-value property are, for now, waiting on a policy that has stalled.

The stakes for the city are not small. A Controller's Office analysis from March 2026 estimated that halving the rate on $10 million-plus sales would cost the city about $390 million over four years, with the first year alone reducing general fund revenue by roughly $93.8 million. With San Francisco facing a projected two-year deficit near $643 million, that revenue gap is a large part of why the cut got shelved rather than passed.

What the November Ballot Could Still Change

The transfer tax fight is not over. A separate ballot measure, backed by advocates who worked on the original Prop I campaign, is gathering signatures for the November 2026 ballot. It would lock in the current higher rate on sales of $10 million or more and require that the revenue be spent specifically on affordable housing, addressing a criticism that current transfer tax proceeds flow into the general fund rather than a dedicated housing account.

Supporters of the original 2020 measure argue the money should keep serving the purpose voters intended. One current supervisor, defending the status quo in an April 2026 Mission Local candidate survey, pointed out that Prop I has generated over $324 million for San Francisco since it took effect. Whether that revenue picture shifts again depends on how the November vote lands, and on whether the mayor's office revives the BUILD Act once the budget situation stabilizes.

For sellers, the practical takeaway is simple: nothing about these rates is settled, but nothing is changing before your next transaction either. Plan around the schedule as it exists today.

What This Means If You're Pricing Near the Line

If your home is likely to appraise or negotiate anywhere between $4.7 million and $5.3 million, or between $9.5 million and $10.5 million, the transfer tax is not a footnote on your closing statement. It is a variable that belongs in the pricing conversation before the sign goes in the yard.

A few things worth working through with your agent before you set a number:

1. Model your net proceeds at a few price points on either side of $5 million or $10 million, not just at your target price. The tax swing can outweigh a modest increase in sale price.
2. Remember the tax is negotiable in the purchase contract even though the seller customarily pays it. In competitive situations, some buyers agree to cover part or all of it.
3. If you are buying near one of these thresholds, understand that a seller pricing just under $5 million or $10 million may have already built the tax cliff into their strategy, which can explain why they are reluctant to negotiate upward past that line even when comparable sales might justify it.

None of this changes what a home is worth. It changes what a seller actually keeps, and that is the number that should drive a list price decision.

Questions Sellers Actually Ask

Does the buyer ever pay the transfer tax instead?

By custom, no. In San Francisco residential sales, the seller pays. The purchase agreement can assign it differently, and in new construction the developer sometimes shifts responsibility to the buyer, but the default expectation on a typical resale is that it comes out of the seller's proceeds.

Can a seller avoid the tax by transferring an LLC instead of a deed?

San Francisco's change-in-ownership rules treat a transfer of more than 50 percent control of an entity that owns city real property the same as a deed transfer for tax purposes. Attempting to structure around Prop I without a real estate attorney and tax advisor reviewing the specifics is a real risk, not a shortcut.

Does the transfer tax reduce what I owe in capital gains tax?

Not directly, but it can be added to your cost basis, which may reduce your taxable gain when you eventually sell. It is worth discussing with a CPA as part of your full net proceeds picture, alongside the federal capital gains exclusion of up to $250,000 for single filers or $500,000 for married couples on a primary residence.

Is the $5 million threshold likely to move?

Not in the near term. The BUILD Act only ever targeted the $10 million and $25 million tiers, not the $5 million line, and that legislation is currently paused. Barring new action from the Board of Supervisors, the schedule described here is the one your transaction will fall under.

If you are weighing a sale near one of these thresholds, or trying to figure out what a purchase actually costs once every line item is on the table, that is exactly the kind of math Rick Lei walks through with clients before a number ever goes on a sign. Let's Connect.
