SF Prop M Progressive Transfer Tax: What Investors Pay at Close
San Francisco's transfer tax is no flat fee. Prop M created six progressive tiers reaching 3% on sales above $25 million. Here is exactly what you owe, who pays it, and how to model it before you list.
San Francisco Prop M (2020) established a progressive real property transfer tax. The rate ranges from 0.5% on sales under $250,000 to 3.0% on sales of $25 million or more. The seller typically pays. For a $2M sale, the tax is approximately $15,000. Verify current rates with the SF Assessor-Recorder at sfassessor.org before closing.
What Is Proposition M?
San Francisco voters approved Proposition M in November 2020. It restructured the city's existing real property transfer tax, converting what had been a tiered-but-relatively-modest levy into a steeply progressive schedule that now reaches 3% on transactions at or above $25 million.
The transfer tax applies whenever real property changes hands in San Francisco. It is separate from — and in addition to — the California Documentary Transfer Tax that all counties collect. Because San Francisco is a consolidated city-county, the tax is administered by the San Francisco Assessor-Recorder's office at sfassessor.org.
For most residential transactions below $1 million, the impact is modest. For luxury residential and commercial sales, Prop M dramatically increased the cost of selling. A $20 million commercial building that would have owed roughly $150,000 under the old schedule now owes $550,000 at the 2.75% rate.
San Francisco's transfer tax can represent the single largest transaction cost at close of escrow — exceeding real estate commissions on high-value sales. Modeling this tax is non-negotiable in any SF exit analysis. Verify all figures with the SF Assessor-Recorder before finalizing a disposition strategy.
Progressive Rate Tiers
San Francisco applies a single flat rate to the entire sale price based on which tier the total consideration falls into. This is not a marginal structure — the rate applies to the full amount, not just the portion above each threshold.
Because the rate applies to the entire sale price (not a marginal structure), crossing a tier threshold creates a sharp jump. A property sold at $4,999,999 pays $37,500 in transfer tax (0.75%). A property sold at $5,000,000 pays $112,500 (2.25%) — a $75,000 increase from a single additional dollar of consideration. This cliff effect is a real negotiation consideration in deal structuring. Consult a tax attorney before pricing decisions near tier boundaries.
| Sale Price Tier | Rate | Tax on Midpoint Example | Effective Rate Context |
|---|---|---|---|
| Under $250,000 | 0.50% | $750 (on $150K) | Lowest tier; rarely seen in SF |
| $250,000 – $999,999 | 0.68% | ~$4,080 (on $600K) | Entry condo / low-end SFR |
| $1M – $4,999,999 | 0.75% | $22,500 (on $3M) | Most SF residential |
| $5M – $9,999,999 | 2.25% | $157,500 (on $7M) | Luxury residential; boutique commercial |
| $10M – $24,999,999 | 2.75% | $412,500 (on $15M) | Mid-size commercial / multifamily |
| $25M+ | 3.00% | $900,000 (on $30M) | Large commercial / trophy assets |
All examples are illustrative. Verify current rates with the SF Assessor-Recorder at sfassessor.org. Rates are subject to change by ballot measure.

Who Pays the Transfer Tax?
By default, the seller pays San Francisco's real property transfer tax. The obligation is statutory — it attaches to the transaction — but the parties may contractually agree to a different allocation in the purchase agreement. In practice, buyer absorption of transfer tax is rare but sometimes negotiated in commercial transactions.
The tax is collected at close of escrow by the title company or escrow officer, who remits payment to the San Francisco Assessor-Recorder as a condition of recording the deed. Without payment, the deed will not be recorded and title will not transfer.
| Party | Default Obligation | Can Negotiate? | Notes |
|---|---|---|---|
| Seller | Pays transfer tax | Yes — may negotiate to split or shift | Statutory default; most common in practice |
| Buyer | Not obligated by default | Yes — may agree to pay in contract | Rare in residential; occasionally in commercial |
| Both parties | 50/50 split if agreed | Yes | Negotiated allocation must appear in purchase agreement |
| Escrow/Title | Collects and remits | No — ministerial function | Tax must be paid before deed is recorded |
If you are a seller, assume you are paying the full tax unless your purchase agreement explicitly says otherwise. I always build transfer tax into my sellers' net sheet from the first conversation so there are no surprises at closing.
Exemptions and Reductions
Not every transfer triggers the full tax. Several categories of transfers are fully exempt or qualify for reduced treatment under the SF Administrative Code. Always verify exemption eligibility with the SF Assessor-Recorder before assuming any relief applies.
| Exemption Category | Status | Key Conditions |
|---|---|---|
| Spousal / RDP transfers | Exempt | Transfer between spouses or registered domestic partners; includes divorce settlement transfers |
| Parent-child transfers | Verify with Assessor | May qualify if meeting family transfer criteria; post-Prop 19 changes — verify current rules |
| Trust transfers (transferor as beneficiary) | Exempt | Transfer into a revocable trust where transferor is sole present beneficiary; no change in beneficial ownership |
| Affordable housing transfers | Reduced or Exempt | Transfers of inclusionary units or deed-restricted affordable housing may qualify; verify with Assessor |
| Government / nonprofit transfers | Exempt in many cases | Transfers to government entities or qualifying nonprofits; specific requirements apply |
| Like-kind exchanges (1031) | Transfer tax still applies | 1031 exchange status does not exempt the transfer tax — only federal income tax treatment is affected |
| Foreclosure / REO | Taxable | Transfer tax applies on trustee's deed; lender absorbs as cost of REO disposition |
| LLC / entity interest transfer | May trigger RETT | Transfer of a controlling interest in an entity owning SF real property may trigger documentary transfer tax; complex rules — consult counsel |
Some investors attempt to avoid transfer tax by selling LLC interests rather than deeds. San Francisco has scrutinized this approach. A transfer of a "controlling interest" in a legal entity that owns real property can trigger the real estate transfer tax. This is a complex area requiring a real estate tax attorney — do not assume entity transfer avoids the tax without current legal advice specific to your structure.
Bay Area County Transfer Tax Comparison
San Francisco's rates are far above what neighboring counties charge. This comparison illustrates the contrast — though note that some cities within these counties (such as Oakland, Berkeley, and others) add their own city transfer tax on top of the county rate. Always check both county and city rates for the specific property location.
| County / City | County Base Rate | City Additional Tax | Combined Rate (Typical) | Notes |
|---|---|---|---|---|
| San Francisco | Consolidated city-county | Prop M tiers (0.5% – 3.0%) | 0.5% – 3.0% | City and county are co-extensive; Prop M rates govern |
| Alameda County | 0.11% ($1.10/$1,000) | Varies by city | 0.11% + city | Oakland adds ~1.5% city tax on most residential |
| Oakland (Alameda Co.) | 0.11% | ~1.50% – 1.80% | ~1.61% – 1.91% | Oakland has own progressive transfer tax tiers |
| Berkeley (Alameda Co.) | 0.11% | ~1.50% | ~1.61% | High for a city; verify current Berkeley rate |
| Contra Costa County | 0.11% | Varies (most cities $0) | ~0.11% | Most CCC cities add no city transfer tax |
| San Mateo County | 0.11% | Varies by city | ~0.11% – 0.50% | Some cities add modest city tax; much lower than SF |
| Santa Clara County | 0.11% | Varies by city | ~0.11% | Most cities add no transfer tax; Mountain View charges modest amount |
| Marin County | 0.11% | Varies (most cities $0) | ~0.11% | Some Marin cities charge modest transfer tax |
All rates are estimates for comparison purposes. Verify exact rates for any specific property location before closing. City transfer taxes change by ballot measure. Check with the applicable county recorder and city finance department.
Investor Exit Math: Modeling Transfer Tax
Before listing any San Francisco investment property, I build a close-cost model that includes transfer tax. Most clients are surprised by the magnitude — especially commercial sellers who bought pre-Prop M when the rate at their price point was dramatically lower.
| Scenario | Sale Price | Rate Tier | Transfer Tax | As % of Typical Commission |
|---|---|---|---|---|
| Entry condo | $750,000 | 0.68% | $5,100 | ~25% of 3% commission ($22,500) |
| Typical SFR | $1,500,000 | 0.75% | $11,250 | ~25% of 3% commission ($45,000) |
| Luxury SFR | $3,500,000 | 0.75% | $26,250 | ~25% of 3% commission ($105,000) |
| Small multifamily | $6,000,000 | 2.25% | $135,000 | ~100% of 2.25% commission ($135,000) |
| Mid commercial | $15,000,000 | 2.75% | $412,500 | Exceeds typical commercial commission |
| Trophy asset | $30,000,000 | 3.00% | $900,000 | Major cost center — often primary exit consideration |
At the $5M cliff, transfer tax jumps from $37,500 to $112,500 — a $75,000 increase. Sellers near tier boundaries sometimes negotiate consideration adjustments or seller-paid credits to optimize net outcomes. This requires coordination between your agent, tax counsel, and the buyer's team.
A 1031 exchange defers federal capital gains tax but does NOT eliminate the SF transfer tax. If you're exchanging out of a San Francisco property, budget for the transfer tax as a real transaction cost in your exchange economics. Your qualified intermediary can confirm the escrow treatment. Verify with your tax advisor and the SF Assessor-Recorder at sfassessor.org.

How to Calculate Your San Francisco Transfer Tax
| Step | Action | Notes |
|---|---|---|
| 1 | Determine your expected sale price or accepted offer | Use total consideration including personal property if included in sale |
| 2 | Identify the Prop M rate tier | Under $250K / $250K–$999K / $1M–$4.99M / $5M–$9.99M / $10M–$24.99M / $25M+ |
| 3 | Multiply sale price by the applicable rate | The rate applies to the entire consideration — not just the portion above the threshold |
| 4 | Check for applicable exemptions | Spousal transfer, revocable trust, affordable housing — verify with SF Assessor-Recorder |
| 5 | Confirm the figure with your escrow officer | The title/escrow company will calculate the official transfer tax amount and include it in the estimated closing statement |
If your expected price is within a few hundred thousand dollars of a tier boundary — particularly near $5M or $10M — discuss pricing strategy with your agent and tax counsel. In some cases, structuring consideration slightly below a cliff threshold (with appropriate buyer credits or personal property allocation if legitimate) can save tens of thousands. These strategies require careful legal review and full disclosure.
