The Sonoma County transfer tax is $1.10 for every $1,000 of the sale price, charged whenever real property changes hands. On a sale near the county’s recent median of about $833,000, that works out to roughly $916. If the property sits inside a city that imposes its own transfer tax, the total bill can run well above that.
How the Rate Works
The county’s authority comes from California Revenue and Taxation Code Section 11911, which allows a charge of $0.55 per $500 of value, or $1.10 per $1,000. The rate applies the same way to residential, commercial, and agricultural transfers anywhere in the county.
The taxable amount is the total consideration paid, minus any existing liens or debt the buyer takes over. If a buyer pays $900,000 and assumes a $200,000 mortgage that stays on title, the tax applies only to the $700,000 difference. That drops the bill from $990 to $770.
City Transfer Taxes on Top of the County Rate
Section 11911 also lets cities inside the county charge their own transfer tax on sales within city limits. General law cities can add up to $0.55 per $1,000, half the county rate. Chartered cities such as Santa Rosa and Petaluma can set higher rates by ordinance, and several Sonoma County cities charge $2.00 or more per $1,000 on top of the county’s $1.10. In those cities the combined rate runs above $3.00 per $1,000.
On an $833,000 sale inside a city charging $2.00 per $1,000, the county piece is about $916 and the city piece about $1,666, for a total north of $2,500. That is nearly three times the bill for a comparable property in unincorporated Sonoma County. Confirm the combined rate with your escrow officer before closing so the city layer does not catch you off guard.
Who Pays
California law does not assign the tax to either party. The buyer and seller negotiate it in the purchase agreement. In Sonoma County the longstanding custom is for the seller to pay, consistent with practice across much of Northern California, but custom is not binding. A buyer may offer to cover it in a competitive market, and a seller may ask the buyer to share it in a slower one.
The County Recorder’s office only cares that the tax is paid before the deed is recorded. Escrow pulls the funds from whichever side of the settlement statement the contract specifies.
Transfers That Are Exempt
Several categories of transfer owe no tax, but the deed itself has to cite the correct exemption code or the recorder will reject it.
Divorce or Legal Separation
Section 11927 exempts transfers that divide community property between spouses as part of a divorce, legal separation, or nullity judgment. It also covers transfers made under a written agreement between spouses in anticipation of such a judgment. The deed must include a signed statement from either spouse declaring the exemption.
Gifts, Inheritance, and Trusts
Section 11930 exempts transfers made as a gift during the owner’s lifetime and transfers that occur because of death. It also covers property placed in trust for the benefit of another person, which is why moving a home into a revocable living trust for estate planning generally does not trigger the tax. The exemption only holds if no money changes hands.
Retitling Into an Entity You Control
Section 11925(d) exempts transfers from your own name into an LLC, partnership, or other legal entity you fully control, as long as the proportional ownership interests are identical before and after. This covers the common move of putting a rental property into a single-member LLC for liability protection.
Foreclosure and Deeds in Lieu
Section 11926 exempts a transfer to a lender through foreclosure or a deed in lieu, but only up to the amount of unpaid debt. If the property’s value exceeds the outstanding loan balance plus accrued interest and foreclosure costs, the tax applies to the excess. The deed has to note the consideration, the unpaid debt, and identify the grantee as the lender or beneficiary.
What the Deed and Recording Package Must Include
Section 11932 requires every taxable document submitted for recording to show the transfer tax amount and the property’s location (incorporated or unincorporated) on the face of the deed. There is no option to file the tax figure on a separate confidential paper; the amount becomes public record. If the transfer is exempt, the deed must state the applicable Revenue and Taxation Code section in place of a dollar amount.
A Preliminary Change of Ownership Report (PCOR) has to accompany the deed. The form tells the Assessor-Recorder’s office about the transaction, the parties, and how the property will be used. Skipping it triggers a $20 additional recording fee. Escrow usually prepares the PCOR, but if you are recording a deed yourself, such as a trust transfer or an interfamily deed, include it.
Recording fees come on top of the tax. When transfer tax is being paid, or the deed states an exemption, Sonoma County charges $14 for the first page and $3 for each additional page. If the deed does not address the transfer tax at all, the first-page fee jumps to $91. A typical two-page grant deed with the tax paid runs $17 in recording fees on top of the tax.
