Californians campaign to limit property taxes (Proposition 13)

Summary

Officially named the People’s Initiative to Limit Property Taxation and popularly known as the Jarvis-Gann Amendment, Proposition 13 was a California constitutional amendment qualified through the state’s ballot-initiative process and approved by California voters on June 6, 1978, by a margin of roughly two to one. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] It capped the real-property tax at 1% of assessed value, restricted annual assessment increases to a maximum of 2% until a change of ownership, and required a two-thirds supermajority in both houses of the state legislature for any increase in state tax rates. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The campaign was built around a state-wide signature drive under the leadership of Howard Jarvis, a former newspaperman and appliance manufacturer turned taxpayer activist, and Paul Gann, with the two named in the Wikipedia article as “the most vocal and visible advocates” of the measure.

Tactics used

  • ballot-initiative petitioning under the California Constitution’s provision allowing a proposed constitutional amendment to be offered to voters once advocates collect the required number of signatures [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • populist narrative framing that connected disparate grievances — fixed-income retirees priced out by reassessment, perceived inequality in school funding after Serrano v. Priest, and the post-AB 80 jump in market-value assessments — into a single anti-property-tax message [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • coalition work between Jarvis and Gann as a two-figure leadership pairing, with the amendment popularly carrying both names onto the ballot as the “Jarvis-Gann Amendment” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • embedding a supermajority constraint (a two-thirds legislative vote for state tax-rate increases and a two-thirds local vote for special taxes) into the measure itself, so the campaign’s signature lived on as a permanent procedural barrier to later tax increases [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • side-by-side ballot positioning against the alternative Proposition 8 (the “split roll”) that was rejected 53–47% on the same June 1978 ballot, with the LA Times-Channel 2 News Survey of roughly 2,500 voters showing that “Among those who voted for Proposition 13, only one in five also voted for Proposition 8, while Proposition 8 was endorsed by fully 91% of those who voted ‘no’ on Proposition 13” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

Background

Proposition 13 is described in the article as drawing on several overlapping grievances that had been accumulating through the 1970s. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] One strand was the displacement of fixed-income homeowners: “Due to severe inflation during the 1970s, reassessments of residential property increased property taxes so much that some retired people could no longer afford to remain in homes they had purchased long before,” with a 2006 study cited in the article reporting that “older voters, homeowners, and voters expecting a tax increase were more likely to vote for Proposition 13.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

A second strand came from the 1971 and 1976 California Supreme Court rulings in Serrano v. Priest, which equalised California school funding by redistributing local property taxes from wealthy to poor school districts and triggered a political backlash in the donor suburbs. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The article frames the political backdrop quantitatively: “Between 1973 and 1977, California state and local government expenditures per $1,000 of personal income were 8.2% higher than the national norm,” and “From 1949 to 1979, public sector employment in California outstripped employment growth in the private sector. By 1978, 14.7% of California’s civilian work force were state and local government employees, almost double the proportion of the early 1950s.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] It also documents that the share of state and local revenues derived from property taxes had risen from 34% at the turn of the 1970s decade to 44% in 1978. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

A third strand was the corruption narrative around county assessors in the early 1960s and the 1966 passage of Assembly Bill 80, which forced assessments back toward market value. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The article notes that “The return to market value in the wake of AB 80 could easily represent a mid-double-digit percentage increase in assessment for many homeowners. As a result, a large number of California homeowners experienced an immediate and drastic rise in valuation, simultaneous with rising tax rates on that assessed value, only to be told that the taxed monies would be redistributed to distant communities,” and that “Cynicism about the favoritism of the tax system towards the wealthy and well-connected persisted into the 1970s. The ensuing anger started to form into a backlash against property taxes which coalesced around Howard Jarvis, a former newspaperman and appliance manufacturer, turned taxpayer activist in retirement.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

What happened

The measure qualified for the ballot through California’s initiative process, “a provision of the California Constitution that allows a proposed law or constitutional amendment to be offered to voters if advocates collect a sufficient number of signatures on a petition.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The substantive text of the amendment, as quoted in the article from California Constitution Article XIII A, Section 1(a), provided: “The maximum amount of any ad valorem tax on real property shall not exceed one percent (1%) of the full cash value of such property.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The article describes the capping rule: “Under Proposition 13, the annual real estate tax on a parcel of property is limited to 1% of its assessed value,” with the assessed value “increased only by a maximum of 2% per year until, and unless, the property has a change of ownership,” at which point “the low assessed value may be reassessed to complete current market value that will produce a new base year value for the property, but future assessments are likewise restricted to the 2% annual maximum increase of the new base year value.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] Reassessment can otherwise be triggered only by a change of ownership or by completion of new construction. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

The two-thirds procedural hooks embedded in the measure required “a two-thirds majority in both legislative houses for future increases of any state tax rates or amounts of revenue collected, including income tax rates,” and “a two-thirds majority in local elections for local governments wishing to increase special taxes.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

Howard Jarvis was active in public framing of the measure in the run-up to the vote; the article’s external links include a Hoover Institution sound recording “of Howard Jarvis discussing Proposition 13 a few weeks before the 1978 election.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The official June 6, 1978 primary-election California Voters Pamphlet is cited in the article as a primary campaign document. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

On June 6, 1978, California voters approved Proposition 13 with 4,280,689 votes in favour (64.79%) against 2,326,167 votes in opposition (35.21%), on a total of 6,606,856 valid votes out of 6,843,001 ballots cast; the article describes the result as “nearly two to one margin” and notes that “Proposition 13 passed with roughly two-thirds of those who voted in favor and with the participation of around two-thirds of registered voters.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The companion Proposition 8 (“split roll”) on the same ballot was rejected 53–47%, with the LA Times-Channel 2 News Survey cited in the article noting that “Proposition 13 was advertised as a stronger tax relief measure than Proposition 8. That is exactly how the voters saw it, and that is exactly what they wanted.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

After passage, Proposition 13 “became article XIII A of the California Constitution.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] In the year after passage, the article reports, “property tax revenue to local governments declined by roughly 60% statewide.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The legal challenges that followed did not displace the measure: the California Supreme Court’s decision in Amador Valley Joint Union High School District v. State Board of Equalization (1978) “confirmed that an initiative cannot ‘revise’ the constitution; Proposition 13, however, was an amendment to the California Constitution and not a revision,” and the U.S. Supreme Court’s 1992 decision in Nordlinger v. Hahn “held that Proposition 13 was constitutional.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

The article frames the downstream effect on U.S. tax politics in the lead: “Passage of the initiative presaged a ‘taxpayer revolt’ throughout the country that is sometimes thought to have contributed to the election of Ronald Reagan to the presidency during 1980. Of 30 anti-tax ballot measures that year, 13 passed.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] Paul Gann followed up with the 1979 Proposition 4 (“Gann Limit”), which he promoted as “The Spirit of 13.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

Outcome

Verdict: won.

Proposition 13 passed on June 6, 1978, with 4,280,689 votes in favour (64.79%) against 2,326,167 votes in opposition (35.21%), on a total of 6,606,856 valid votes; voter participation is described in the article as around two-thirds of registered voters. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The measure took its place in the California Constitution as Article XIII A, “to cap property taxes and limit property reassessments to when the property changes ownership, and to require a 2/3 majority for tax increases in the state legislature.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] The article describes Proposition 13 as “California’s most famous and influential ballot measure.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978] In the year after passage, “property tax revenue to local governments declined by roughly 60% statewide.” [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]

Lessons

  • A ballot-initiative campaign can convert disparate economic grievances — retiree displacement from inflationary reassessment, perceived inequity in school-funding redistribution, and post-AB 80 market-value reassessment shocks — into a single constitutional amendment, when the procedural vehicle is in place. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • Embedding a procedural supermajority (here, a two-thirds legislative vote for state tax-rate increases and a two-thirds local vote for special taxes) inside the substantive measure turns one electoral win into a durable constraint on later legislation. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • Pairing the campaign’s two named public figures in the popular name of the amendment (the “Jarvis-Gann Amendment”) made the leadership team itself a brand that travelled beyond the campaign into later reform politics, including Gann’s 1979 “Spirit of 13” follow-on. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • A “stronger” tax-relief framing can beat a competing “split roll” alternative on the same ballot: on June 6, 1978, Prop 13 passed 65–35 while Prop 8 was rejected 53–47, with 91% of Prop-13-No voters also backing Prop 8 and only one in five Prop-13-Yes voters doing so. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
  • Capping the assessment at acquisition value transfers fiscal risk from households to local-government budgets: in the year after passage, property tax revenue to local governments declined by roughly 60% statewide. [source: us-californians-campaign-to-limit-property-taxes-proposition-13-1978]
