Property Taxes In California

Updated August 7, 2026

13 min read

Property tax is usually the largest single line item on a California rental property's operating statement, and it is the one an owner has the least direct control over. For a management company, the practical questions are narrow: how the county arrives at the number, which exemptions your owners do and do not qualify for, when payment is due, and what the appeal window looks like if an assessment comes in high.

This guide covers those mechanics for California, sourced to the state's own statutes and to county assessor and treasurer offices. Rates and dollar thresholds change; the citations stay put, so you can confirm the current figure before advising an owner.

How Property Is Assessed

California county assessors value locally assessed real property, while the State Board of Equalization sets statewide assessment rules, publishes the annual inflation factor and directly assesses certain utility and railroad property. The lien date is January 1. California does not use an assessment ratio, and there is no separate class or ratio for rentals: every parcel is assessed on its factored base year value, which is the market value established at the last change in ownership or new construction, indexed forward. The practical consequence is that two identical rentals on the same street can carry very different tax bills depending on when each was last purchased.

Full cash value means the county assessor's valuation of real property as shown on the 1975-76 tax bill, or the appraised value of real property when purchased, newly constructed, or a change in ownership has occurred after that assessment. (California Constitution, Article XIII A, Section 2)
The base year value is adjusted annually by the lower of the percentage change in the California Consumer Price Index or two percent, and the resulting taxable value is called the factored base year value. (California Constitution, Article XIII A, Section 2)
The State Board of Equalization publishes the annual inflation factor each year in a Letter To Assessors that county assessors statewide use in preparing the assessment roll. (BOE Letters To Assessors, annual California Consumer Price Index letter)
A decline in value occurs in any year in which the current market value of real property is less than its adjusted base year value as of the lien date, January 1, and the assessor then enrolls the lower value. (Proposition 8 decline in value)

How The Tax Is Calculated

The California formula is factored base year value multiplied by the applicable tax rate, which is the one percent basic levy plus any voter-approved debt rates, with special assessments and non-ad valorem charges added on the bill. Proposition 13 is the cap: the base year value can rise by no more than two percent per year, and it resets to market value only on a change in ownership or new construction. Proposition 8 provides a temporary downward adjustment when market value falls below the factored base year value, and those reduced values can climb back faster than two percent until they reach the original factored base year value.

Proposition 13 caps growth in a property's assessed value at no more than two percent a year unless market value falls below the factored base year value, and the annual adjustment is the lower of the California Consumer Price Index change or two percent. (California Constitution, Article XIII A, Section 2)
Once a property is in Proposition 8 decline in value status, the assessor reviews the assessment annually, and values can increase by more than two percent in a year, but the assessed value cannot exceed the existing factored base year value unless ownership changes or new construction occurs. (Proposition 8 decline in value)
For the 2026 assessment roll the inflation factor is 1.02, based on a California Consumer Price Index increase from 343.108 in August 2024 to 354.456 in August 2025, meaning the full two percent increase applies for the 2026 lien date. (BOE Letter To Assessors 2026/002, 2026-27 California Consumer Price Index)

Tax Rates And Who Sets Them

California does not use a mill levy set freely by local boards. The maximum ad valorem tax on real property is one percent of full cash value, collected by counties and apportioned to local districts. Above that one percent, a parcel can carry additional rates only to service voter-approved bonded indebtedness, plus separately authorized special assessments and non-ad valorem charges. That is why an actual California tax bill usually lands somewhat above one percent of assessed value rather than exactly at it.

The maximum amount of any ad valorem tax on real property is one percent of full cash value, collected by counties and apportioned according to law to the districts within the counties. (California Constitution, Article XIII A, Section 1)
The one percent limitation does not apply to ad valorem taxes or special assessments to pay interest and redemption charges on indebtedness approved by voters before July 1, 1978, on bonded indebtedness for acquisition or improvement of real property approved by a two-thirds vote after July 1, 1978, or on school facility bonds approved by fifty-five percent of voters subject to accountability requirements. (California Constitution, Article XIII A, Section 1)

Exemptions And What Rentals Do Not Get

California's main residential relief is the homeowners' exemption, and it is explicitly limited to owner-occupied principal residences. There is no equivalent exemption for rental or investment property, so an investor owner simply pays on the full factored base year value. The disabled veterans' exemption is likewise residence-based. In practice the meaningful tax planning lever for California investors is not exemptions but avoiding an unnecessary change in ownership that would reset the base year value.

The California Constitution provides a 7,000 dollar reduction in the taxable value for a qualifying owner-occupied home, and the home must be the principal place of residence of the owner on the lien date, January 1. (California homeowners' exemption)
DOES NOT APPLY TO RENTALS: because the homeowners' exemption requires the property to be the owner's principal place of residence on January 1, it is not available for rental or other non-owner-occupied dwellings. (California homeowners' exemption)
A first-time claimant must file no later than February 15 to receive the full exemption for that year, and December 10 is the last day to terminate the homeowners' exemption without penalty, which matters when an owner converts a former residence into a rental. (California homeowners' exemption filing and termination dates)
DOES NOT APPLY TO RENTALS: Proposition 19 eliminated the parent-child and grandparent-grandchild exclusion for real property other than the family home and family farm, so rental and investment property inherited on or after February 16, 2021 is reassessed to current market value. (Proposition 19, operative February 16, 2021)
For the family home that does qualify under Proposition 19, the property must be the principal residence of both transferor and transferee, and the exclusion is limited to the factored base year value plus one million dollars, with any excess added to the taxable value. (Proposition 19)

This is the part worth being precise about with owners. Most of the headline California exemptions are tied to the property being someone's primary residence, which means a tenant-occupied rental does not qualify. Promising an owner a homestead benefit that their investment property cannot receive is an easy way to lose trust, so check the occupancy condition before it comes up in a conversation.

Payment Deadlines And Penalties

California bills secured property tax on a July through June fiscal year, in two installments with fixed delinquency dates that are widely misread because the due date and the delinquency date are weeks apart. A ten percent penalty attaches to each installment that misses its delinquency date, and the second installment picks up an additional cost. If the full year remains unpaid at the end of the fiscal year, the parcel goes to tax-defaulted status on July 1 and begins accruing monthly redemption penalties.

The fiscal tax year runs from July 1 of one year through June 30 of the next, and annual secured bills are mailed in October. (Los Angeles County Treasurer and Tax Collector, secured property taxes)
The first installment is due November 1 and is delinquent after December 10, and the second installment is due February 1 and is delinquent after April 10. (Los Angeles County Treasurer and Tax Collector, secured property taxes)
A ten percent penalty applies to each unpaid installment after its delinquency date, and an additional ten dollar cost is added to the second installment for notice purposes. (Los Angeles County Treasurer and Tax Collector, secured property taxes)
If the total annual payment is not received or postmarked by June 30, the unpaid taxes become defaulted on July 1, a fifteen dollar redemption fee is charged, and defaulted taxes accrue additional penalties of one and one-half percent of the base tax per month. (Los Angeles County Treasurer and Tax Collector, secured property taxes)

Appealing An Assessment

California appeals are heard by a county assessment appeals board, a quasi-judicial body of impartial members, or by a hearing officer. The regular filing period is July 2 to September 15 in counties where the assessor notifies all real property taxpayers of value by August 1, and July 2 to November 30 elsewhere, so the deadline is county-specific and must be confirmed each year. Base year value and supplemental assessment appeals run on a separate sixty-day clock. For most rental property the owner, not the assessor, carries the burden of proof.

The regular filing period is July 2 to September 15, but if the assessor does not provide notice to all taxpayers of real property on the local secured roll of their assessed value by August 1, the last day of the filing period extends to November 30. (BOE Letter To Assessors 2025/020, County Assessment Appeals Filing Period)
Appeals of a base year value or a supplemental assessment must be filed within sixty days of the mailing of the notice or the tax bill, and calamity reassessment appeals within six months of the notice. (California assessment appeals filing periods)
The assessor bears the burden of proof for owner-occupied single-family homes, escape assessments and penalty assessments, and the property owner bears the burden for all other property types, which includes rental and investment property. (California assessment appeals, burden of proof)
Acceptable evidence includes comparable sales ideally within ninety days of the assessment date, professional appraisals or expert testimony, and income or replacement cost analyses, and any information provided with the application must also be presented at the hearing in order to be considered evidence. (California assessment appeals, evidence)
The law allows up to two years for an application to be resolved, and if the appeal is not heard within two years the applicant's claimed value may temporarily become the taxable value by default. (California assessment appeals, two-year rule)

What Happens If Taxes Go Unpaid

California does not run an annual tax lien certificate auction the way Arizona and Florida do. Instead unpaid taxes put the parcel into tax-defaulted status, redemption penalties accrue monthly, and only after a long default period does the tax collector gain the power to sell. That gives owners a comparatively long runway, but the accrued penalties are substantial and the eventual sale extinguishes the owner's interest.

The tax collector has the power to sell tax-defaulted property five years or more after the property has become tax defaulted, or three years or more in the case of nonresidential commercial property, provided the property remains unredeemed. (California Revenue and Taxation Code section 3691)
A county may elect to extend the timeline for nonresidential commercial property to match the five-year residential standard, and disaster-damaged property receives a tolling provision that pauses the clock until five years elapse from the damage date. (California Revenue and Taxation Code section 3691)
For nonresidential property defaulted less than five years, enhanced notice procedures apply, including certified mail notification to deed of trust beneficiaries and mortgagees at least forty-five to one hundred twenty days before the intended sale. (California Revenue and Taxation Code section 3691)
Defaulted taxes accrue penalties of one and one-half percent of the base tax per month following default, in addition to the ten percent penalties already attached to each delinquent installment. (Los Angeles County Treasurer and Tax Collector, secured property taxes)

What Is Different For Rental Property

California applies no separate assessment class or ratio to rentals, but three rules hit investors specifically. First, no homeowners' exemption. Second, Proposition 19 removed the parent-child exclusion for rental and investment property, so a portfolio passing to the next generation is reassessed. Third, transfers of interests in the LLC, partnership or corporation that holds the property can themselves be a change in ownership that resets the base year value, which surprises owners who assume that keeping the deed unchanged keeps Proposition 13 intact.

Purchasing or transferring ownership interests in a legal entity does not by itself trigger reassessment, but a change in ownership is triggered when a person or entity obtains control through direct or indirect ownership of more than fifty percent of the voting stock of a corporation or a majority interest in a partnership or limited liability company. (California Revenue and Taxation Code section 64)
When original co-owners cumulatively transfer more than fifty percent of their interests in an entity, reassessment occurs as of the date of the transfer that crosses that threshold, so a series of small transfers in a family holding LLC can trigger a full reset. (California Revenue and Taxation Code section 64)
Under Proposition 19, rental properties and investment land no longer qualify for the intergenerational transfer exclusion, which is limited to family homes and family farms. (Proposition 19, operative February 16, 2021)
Because the property owner bears the burden of proof at an assessment appeals board hearing for property other than owner-occupied single-family homes, an investor appealing a rental assessment must come to the hearing with its own comparable sales, appraisal or income analysis. (California assessment appeals, burden of proof)

Recent Changes Worth Tracking

Effective 2026 lien date, January 1, 2026: The inflation factor for the 2026 assessment roll is 1.02, the full two percent maximum. The State Board of Equalization derived it from the August 2024 to August 2025 California Consumer Price Index change because the federal government shutdown in fall 2025 prevented the Bureau of Labor Statistics from publishing the regional indexes normally used for the October figure. (BOE Letter To Assessors 2026/002, 2026-27 California Consumer Price Index)

Working This Into Your Operations

The two dates that matter operationally are the assessment notice and the appeal deadline. Assessment notices arrive on a predictable schedule, the appeal window is short and unforgiving, and an owner who misses it waits a full cycle. Put both on the calendar per county, escrow for the bill rather than treating it as a surprise, and flag unusual valuation jumps to owners while there is still time to act on them.

This guide is a starting point for professional managers, not tax or legal advice. For a specific assessment, appeal, or delinquency, work with a California property tax professional, and confirm current figures with the county assessor or the California State Board of Equalization.
