Does a change in control of an entity trigger California documentary transfer tax?
Edvin Givargis Published 5 minute read
The short answer
Yes, in every California county, since the Supreme Court decided 926 North Ardmore Avenue, LLC v. County of Los Angeles in 2017. Selling the interests in an entity that holds California real property is treated as selling the realty itself whenever the transfer works a change in ownership under the Proposition 13 rules, principally an acquisition of more than 50 percent control under Revenue and Taxation Code Section 64(c), or the cumulative transfer of more than 50 percent of the interests of original co-owners under Section 64(d). No deed is required, no recording is required, and structuring the deal as an interest sale no longer avoids the tax. For institutional real estate, where entity-level transfers are the norm rather than the exception, the documentary transfer tax became a routine deal cost rather than a technicality, and in the charter cities with graduated rates it can be one of the largest state and local costs in the transaction.
What Ardmore held
The Documentary Transfer Tax Act lets counties and cities tax each written instrument by which lands or realty sold are conveyed (Revenue and Taxation Code Section 11911). For decades the working assumption was that the tax reached deeds, and that transfers of partnership or LLC interests were outside it except in narrow cases. Ardmore ended that. The transfers there were partnership interests in an entity that indirectly held an apartment building; roughly 90 percent of the interests moved between family trusts, no deed was recorded, and Los Angeles County billed the transfer tax anyway. The Supreme Court affirmed, holding that realty is sold within the meaning of the Act when a written instrument, made for consideration, transfers beneficial ownership of real property, directly by deed or indirectly through a transfer of entity interests. And for deciding when an entity transfer moves beneficial ownership, the court adopted the Proposition 13 change in ownership rules: Sections 64(c) and 64(d) identify precisely the indirect transfers that are real rather than paper. The court required a written instrument and consideration, but expressly rejected the argument that only recorded documents are taxable. One justice dissented on the ground that grafting 1979 property tax concepts onto a 1967 stamp tax expanded it beyond its text; that concern is now a footnote, because the majority's rule is the law.
The two triggers
Section 64(c) is the change in control rule: a person or entity obtains more than 50 percent of the voting stock of a corporation, or a majority of the capital and profits interests of a partnership or LLC. One buyer crossing the line in one transaction is the classic case. Section 64(d) is the original co-owner rule: where real property was contributed to an entity in a proportional-interest transfer that was excluded from change in ownership at the time, the later cumulative transfer of more than 50 percent of the original co-owners' interests is a change in ownership even though no single buyer obtained control. Ardmore itself was a Section 64(d) case, which is worth remembering, because Section 64(d) catches patterns that no one in the deal thinks of as a sale of the company: successive estate planning transfers, staged buyouts among founders, and recapitalizations that cumulatively move the original owners past the halfway mark. The same events that trigger property tax reassessment therefore now carry a second, immediate cost at the recorder's office, and the two analyses should always be run together.
Rates, and why the city matters more than the county
The statutory rate is modest: 55 cents per $500 of consideration or value, with general law cities able to impose half that amount as a credit against the county tax. The real money is in the charter cities, which set their own rates on top. San Francisco's graduated schedule climbs to several percent of the price on large transfers, and Los Angeles adds its base city rate plus, since 2023, the Measure ULA tiers that take several additional percent of high-value transfers. On a nine-figure entity deal in the wrong city, the transfer tax can exceed every other state and local cost in the transaction combined, which is why the change in control analysis belongs in the model at the letter of intent stage, not at closing. The measure of the tax on an entity transfer is the value of the California realty whose beneficial ownership moved, and allocating consideration credibly among properties and jurisdictions is part of the compliance work.
How the counties find out
Entity transfers do not pass through escrow or the recorder, but they are not invisible. A legal entity that undergoes a change in control or change in ownership must file a statement of change in control and ownership of legal entities (Form BOE-100-B) with the state within 90 days, and the information is shared with county officials; late or missed filings carry penalties of their own. Post-Ardmore, counties use exactly this reporting to issue transfer tax bills on unrecorded entity transactions, sometimes years after closing. The practical consequence is that not volunteering the tax is not a strategy: the reassessment reporting the deal already requires will surface the transfer, and the bill arrives with interest and penalty exposure attached rather than as a negotiated closing cost.
Practice notes
Diligence on any California entity deal should establish three things before pricing is final: whether the transaction crosses a Section 64(c) or 64(d) line, which county and city rates apply to each parcel, and who bears the tax by contract, because the statute's incidence is not self-allocating and the amounts in charter cities are too large to leave to a boilerplate proration clause. Transfers that stay off the triggers stay untaxed: proportional interest transfers that merely change the form of ownership remain excluded, and partnership interest transfers in a continuing partnership that work no change in ownership remain outside the Act (Revenue and Taxation Code Section 11925), so the sequencing of a multi-step restructuring can determine whether tax is due at all. The Section 64(d) original co-owner ledger deserves particular care in family and founder structures, where no one is tracking cumulative percentages until the transfer that crosses the line. And where a change in control has already happened without a transfer tax payment, the BOE-100-B filing, the reassessment, and the transfer tax exposure should be addressed together, on the taxpayer's initiative, rather than serially as each agency finds the deal.
