If you are buying a home, comparing housing costs, or reviewing your annual tax bill, you may be wondering how much is property tax in California in 2026. California’s basic property tax is generally 1% of taxable assessed value, but your actual bill can be higher because of voter-approved bonds, Mello-Roos special taxes, parcel taxes, and other local assessments.
The answer to how much is property tax in California also depends heavily on Proposition 13. This law generally limits annual increases in a property’s assessed value, which means two similar homes can have very different tax bills depending on when each property was purchased.
This guide explains California property tax rates, Proposition 13, county differences, tax calculations, reassessment rules, supplemental bills, Mello-Roos, exemptions, Proposition 19, ADUs, solar systems, senior programs, appeals, deadlines, and how to estimate the tax for a specific home.
Quick Answer: How Much Is Property Tax in California?
For most homeowners trying to calculate how much is property tax in California, a useful starting formula is:
Taxable assessed value × 1% + voter-approved debt + other property-specific charges
For example, if a home is newly assessed at $800,000:
$800,000 × 1% = $8,000 per year
That equals about $667 per month before additional local charges.
Proposition 13 generally limits annual inflationary increases in a property’s factored base-year value to no more than 2%. For the 2026–27 assessment year, the official inflation factor is 2%.
Tax Foundation’s 2026 comparison also reports a California effective property tax rate of about 0.70% of owner-occupied housing value. However, that effective rate should not be confused with California’s 1% base rate on taxable assessed value.
California Property Tax 2026 at a Glance
| Property Tax Item | 2026 Information |
|---|---|
| Basic Proposition 13 rate | 1% of taxable assessed value |
| Additional ad valorem rate | Qualifying voter-approved bonded debt |
| Maximum normal annual assessment growth | Generally 2% |
| 2026–27 Prop 13 inflation factor | 2% |
| Reported statewide effective rate | About 0.70% |
| Property tax lien date | January 1 |
| First installment due | November 1 |
| First installment delinquent | After December 10 |
| Second installment due | February 1 |
| Second installment delinquent | After April 10 |
| Homeowners’ Exemption | Up to $7,000 off taxable value |
| Full Homeowners’ Exemption deadline | February 15 |
California’s regular secured property taxes are normally paid in two installments. The first is due November 1 and becomes delinquent after December 10. The second is due February 1 and becomes delinquent after April 10.
Key Takeaways
- California’s basic property tax is generally 1% of taxable assessed value.
- The total bill may exceed 1% because of voter-approved debt and local charges.
- Proposition 13 generally limits normal annual growth in factored base-year value to a maximum of 2%.
- The 2026–27 Proposition 13 inflation factor is 2%.
- A qualifying home purchase usually establishes a new base-year assessment at current fair market value.
- New construction can add assessed value without automatically reassessing the entire existing property.
- Long-time homeowners may pay significantly less than recent buyers of comparable homes.
- Buyers should check Mello-Roos, parcel taxes, direct assessments, and supplemental-tax exposure before closing.
- County effective rates are useful for comparison but should not be used as exact quotes for individual homes.
How Much Is Property Tax in California and How Does It Work?
Understanding how much is property tax in California starts with taxable assessed value. California generally uses an acquisition-value system under Proposition 13. When a property changes ownership, the county assessor usually establishes a new base-year value based on current fair market value. After that, the property’s taxable value may generally increase each year by the applicable inflation factor, subject to the Proposition 13 limit.
A simplified formula is:
Taxable Assessed Value × Applicable Tax Rate + Other Charges = Total Property Tax Bill
Suppose a buyer purchases a home for $900,000 and its fair market value is also approximately $900,000.
The basic tax estimate would be:
$900,000 × 1% = $9,000 per year
If that property also has $2,000 in bonds, Mello-Roos, or other assessments, the total annual bill could be around $11,000. That is why the simple 1% calculation is a starting point rather than a guaranteed final amount.
What Is Proposition 13?
Proposition 13 was approved by California voters in 1978 and remains the foundation of the state’s real property tax system.
It generally:
- Limits the basic property tax rate to 1% of taxable assessed value.
- Allows additional rates for qualifying voter-approved bonded debt.
- Uses acquisition value to establish a property’s base-year value.
- Limits normal annual inflationary increases to no more than 2%.
- Allows reassessment after qualifying changes in ownership.
- Allows qualifying new construction to be assessed.
Why Can Two Similar California Homes Have Different Property Taxes?
This is one reason there is no single simple answer to how much is property tax in California for every homeowner.
Consider two homes that are each worth approximately $1 million today.
| Homeowner | Current Market Value | Example Taxable Value | Basic 1% Tax |
|---|---|---|---|
| Long-time owner | $1,000,000 | $450,000 | $4,500 |
| Recent buyer | $1,000,000 | $1,000,000 | $10,000 |
The long-time homeowner may have a much lower Proposition 13 assessment because the taxable value has been limited over many years.
The recent buyer generally receives a new base-year value based on current fair market value after a qualifying ownership change.
California Property Tax Increase for 2026
For the 2026–27 assessment year, California’s official Proposition 13 inflation factor is 2%.
For example:
Previous taxable value: $600,000
Adjusted taxable value: $600,000 × 1.02 = $612,000
At the basic 1% rate:
- Previous basic tax: $6,000
- New basic tax: $6,120
- Difference: $120
This is a simplified example and assumes there is no ownership change, new construction, exemption change, Proposition 8 reduction, or change in local charges.
Does Proposition 13 Limit the Entire Tax Bill to a 2% Increase?
No.
The 2% limitation generally applies to annual growth in the property’s factored base-year value.
The total bill can increase by more because of:
- New construction.
- Change in ownership.
- Voter-approved debt.
- Mello-Roos.
- Parcel taxes.
- Direct assessments.
- Changes in exemptions.
- Restoration after a Proposition 8 reduction.
How Much Is Property Tax in California by Home Value?
If you want a fast answer to how much is property tax in California for different home values, the table below uses the basic 1% rate.
Taxable Assessed ValueBasic Annual TaxApprox.
| Home Value | Basic 1% Tax | Monthly Amount |
|---|---|---|
| $300,000 | $3,000 | $250 |
| $400,000 | $4,000 | $333 |
| $500,000 | $5,000 | $417 |
| $600,000 | $6,000 | $500 |
| $750,000 | $7,500 | $625 |
| $800,000 | $8,000 | $667 |
| $900,000 | $9,000 | $750 |
| $1,000,000 | $10,000 | $833 |
| $1,250,000 | $12,500 | $1,042 |
| $1,500,000 | $15,000 | $1,250 |
| $2,000,000 | $20,000 | $1,667 |
These figures exclude additional bonds, Mello-Roos, parcel taxes, and direct assessments.
How Much Is Property Tax in California on a $500,000 House?
For a taxable assessed value of $500,000:
$500,000 × 1% = $5,000 per year
That is approximately $417 per month before other charges.
Therefore, if someone asks how much is property tax in California on a $500,000 home, about $5,000 in basic annual property tax is a useful starting estimate.
How Much Is Property Tax in California on a $750,000 House?
For a taxable value of $750,000:
$750,000 × 1% = $7,500 per year
That equals approximately $625 per month before additional charges.
How Much Is Property Tax in California on a $1 Million House?
For a $1 million taxable assessment:
$1,000,000 × 1% = $10,000 per year
That works out to approximately $833 per month.
A home with Mello-Roos, school bonds, parcel taxes, or other assessments could have a noticeably higher total bill.
How Much Is Property Tax in California on a $1.5 Million Home?
At $1.5 million of taxable assessed value:
$1,500,000 × 1% = $15,000 annually
That equals approximately $1,250 per month before additional local charges.
How Much Is Property Tax in California by County?
Another common way people search how much is property tax in California is by county.
California’s Proposition 13 rules apply statewide, but effective property-tax rates differ among counties because of differences in home values, assessment histories, voter-approved debt, and local charges.
| California County | Reported Effective Rate |
|---|---|
| Los Angeles County | 0.67% |
| Orange County | 0.64% |
| San Diego County | 0.67% |
| Riverside County | 0.83% |
| San Bernardino County | 0.73% |
| Alameda County | 0.76% |
| Contra Costa County | 0.78% |
| Sacramento County | 0.76% |
| Kern County | 0.89% |
| San Francisco County | 0.72% |
| Santa Clara County | 0.68% |
| San Mateo County | 0.63% |
| San Joaquin County | 0.79% |
| Monterey County | 0.63% |
| Santa Barbara County | 0.59% |
| Sonoma County | 0.65% |
California’s statewide effective property tax rate is approximately 0.70% in Tax Foundation’s 2026 comparison. These percentages are effective rates based on taxes paid relative to home values. They should not be used as the exact property tax rate for a newly purchased home.
Why Is California’s Effective Property Tax Rate Below 1%?
The difference comes from the way each number is calculated. California’s 1% basic property tax rate applies to taxable assessed value.
An effective property tax rate usually compares the amount actually paid with the home’s current market value.
For example:
- Current market value: $1,000,000
- Proposition 13 assessed value: $500,000
- Basic tax: $5,000
The homeowner is paying 1% of the assessed value, but $5,000 is only 0.5% of the property’s current $1 million market value.
This explains why statewide effective-rate statistics can be below 1%.
How to Calculate Property Tax Before Buying a California Home
For buyers trying to estimate how much is property tax in California, the seller’s current bill can be misleading. Suppose a seller bought a property many years ago and currently has a taxable value of $400,000. The property now sells for $1 million.
The seller’s basic tax may be close to $4,000.
But after a qualifying sale, the buyer’s new base-year value may be much closer to $1 million.
That creates a basic estimate of:
$1,000,000 × 1% = $10,000 per year
California Buyer Property Tax Formula
Start with:
Expected new assessed value × 1%
Then investigate:
- Voter-approved bond charges.
- Mello-Roos.
- Community Facilities District taxes.
- Parcel taxes.
- Direct assessments.
- Supplemental property taxes.
This provides a more realistic estimate of future ownership costs.
How to Find Property Tax for a Specific California Address
If you want to know how much is property tax in California for one exact home, use official county records instead of a statewide or county average.
Start by finding the property’s Assessor’s Parcel Number, or APN.
Then check:
- Current taxable assessed value.
- Current secured property tax bill.
- Tax Rate Area.
- Voter-approved debt.
- Parcel taxes.
- Direct assessments.
- Mello-Roos or CFD charges.
Because property tax administration is primarily handled by California counties, the most accurate information for an individual home comes from the county assessor and tax collector.
What Is Mello-Roos?
Mello-Roos is a special tax imposed in certain Community Facilities Districts. These districts may finance public infrastructure, schools, roads, public safety facilities, or other authorized improvements.
Mello-Roos is important when estimating how much is property tax in California because it can make the total annual bill much higher than the basic 1% estimate. It is particularly common in some newer developments.
Before purchasing a home, review the current tax bill for:
- CFD charges.
- Community Facilities District.
- Mello-Roos.
- Special tax.
- Direct assessment.
Does Buying a House Reset Property Taxes in California?
A qualifying change in ownership generally results in a new base-year value based on current fair market value.
That means a buyer normally should not assume the seller’s old assessed value will continue.
For example:
- Seller’s taxable value: $350,000
- Purchase price: $900,000
- Seller’s basic tax: about $3,500
- Buyer’s possible new basic tax: about $9,000
This difference is one of the most important factors for buyers calculating how much is property tax in California after purchasing a home.
What Else Can Trigger Reassessment?
A property may also receive additional assessed value after qualifying new construction.
Common reassessment-related events include:
- Property sale.
- Certain gifts.
- Some inheritance transfers.
- Certain trust or ownership changes.
- New construction.
- Major additions.
Specific exclusions may apply depending on the transaction.
Do Home Improvements Increase Property Tax in California?
Not every renovation increases property taxes. Routine repairs and maintenance generally do not have the same effect as assessable new construction.
Work that may be more likely to create taxable new value includes:
- Adding square footage.
- Building a room addition.
- Constructing a pool.
- Adding a substantial new structure.
- Major rehabilitation.
- Converting a property to a significantly different use.
The assessor generally determines the market value added by qualifying new construction.
Does an ADU Increase Property Tax in California?
An Accessory Dwelling Unit can increase assessed value because it may qualify as new construction. However, an ADU generally does not cause the entire existing house to be reassessed at current market value.
For example:
| ADU Assessment Example | Amount |
|---|---|
| Existing taxable value | $500,000 |
| Example added ADU value | $200,000 |
| Illustrative combined value | $700,000 |
The county assessor determines the actual taxable value attributable to the ADU.
Do Solar Panels Increase Property Tax in California in 2026?
California currently provides a new-construction exclusion for qualifying active solar energy systems.
For 2026, qualifying systems may receive that exclusion.
However, the current exclusion is scheduled to become inoperative on January 1, 2027.
Systems that qualified before that date generally continue to receive the exclusion until a later qualifying change in ownership.
Homeowners planning late-2026 solar installations should verify the current rule and project timing with the county assessor.
What Is a Supplemental Property Tax Bill?
A supplemental property tax bill is separate from the normal annual tax bill.
It can be issued after a qualifying ownership change or completion of new construction.
The simplified calculation is:
New Assessed Value − Previous Taxable Value = Supplemental Assessment
Example:
| Supplemental Tax Example | Amount |
|---|---|
| Previous assessed value | $400,000 |
| New assessed value | $700,000 |
| Difference | $300,000 |
| Approx. full-year basic tax difference | $3,000 |
The actual supplemental tax is prorated based on when the change occurred.
Depending on timing, one or more supplemental assessments may be issued.
Important Tip for Buyers
A supplemental bill may not automatically be included in your mortgage escrow account. If you receive one, contact both your mortgage servicer and county tax collector to confirm payment arrangements.
Secured, Supplemental and Unsecured Property Tax
| Tax Type | General Meaning |
|---|---|
| Secured property tax | Property tax secured by real estate |
| Supplemental property tax | Added assessment after ownership change or new construction |
| Unsecured property tax | Mainly taxable property not secured by real estate |
Most homeowners primarily deal with secured and supplemental property taxes.
What Is Proposition 19?
Proposition 19 changed California property tax rules for certain homeowners moving to new residences and for some family transfers.
Homeowners Age 55 and Older
Qualifying homeowners age 55 or older may transfer an eligible taxable value from a principal residence to a replacement principal residence anywhere in California.
Similar provisions apply to certain severely disabled homeowners and qualifying wildfire or natural-disaster victims. Eligible homeowners can generally make a qualifying transfer up to three times.
Parent-to-Child Transfers
Proposition 19 also narrowed California’s previous parent-child reassessment exclusion. For qualifying family-home transfers, specific residence and value requirements apply.
For transfers occurring from February 16, 2025 through February 15, 2027, the adjusted Proposition 19 exclusion amount is $1,044,586 under the applicable value calculation.
California Homeowners’ Exemption
California’s Homeowners’ Exemption can reduce the taxable assessed value of an eligible principal residence by up to $7,000.
At the basic 1% tax rate:
$7,000 × 1% = approximately $70 in annual basic-tax savings
The exemption reduces taxable value. It does not reduce your tax bill by $7,000.
A first-time claimant generally needs to file by February 15 to receive the full exemption for the year.
Disabled Veterans’ Property Tax Exemption for 2026
Qualifying disabled veterans and certain surviving spouses may qualify for a larger exemption.
| 2026 Disabled Veterans’ Exemption | Amount |
|---|---|
| Basic exemption | $180,671 |
| Low-income exemption | $271,009 |
| Low-income household limit | $81,131 |
Eligibility requirements apply, and the basic and low-income exemption amounts are alternatives rather than amounts that are added together.
Can Seniors Freeze Property Taxes in California?
California does not provide a universal property-tax freeze based only on age.
However, qualifying older homeowners may benefit from:
- Proposition 13 assessment limits.
- Proposition 19 base-year-value transfers.
- California’s Property Tax Postponement Program.
These programs have different eligibility requirements.
California Property Tax Postponement Program
California’s State Controller operates a Property Tax Postponement Program for certain eligible homeowners.
For the 2026–27 program, qualifying applicants generally must:
- Be at least 62 years old, blind, or disabled.
- Own and occupy the property as a principal residence.
- Have household income of $57,002 or less.
- Have at least 40% equity.
2026–27 Filing Schedule
| Event | Date |
|---|---|
| Applications available | September 2026 |
| Filing opens | October 1, 2026 |
| Filing closes | February 10, 2027 |
The program postpones tax. It does not eliminate the debt.
Can Property Taxes Go Down in California?
Yes.
Proposition 8 allows temporary reductions when a property’s current market value falls below its Proposition 13 factored base-year value.
If the market later recovers, the assessment may increase again.
Can the Assessment Increase More Than 2% After a Proposition 8 Reduction?
Yes.
A temporarily reduced Proposition 8 assessment can increase by more than 2% as market value recovers.
However, without another reassessment event, the taxable value generally cannot exceed the applicable Proposition 13 factored base-year value.
California Wildfire and Disaster Property Tax Relief
California homeowners whose property is damaged by wildfire, earthquake, flooding, or another qualifying calamity may be eligible for temporary assessment relief.
Generally, the loss must be at least $10,000 in current market value.
Property owners should file with the appropriate county assessor within the applicable deadline.
Qualifying reconstruction may also preserve prior Proposition 13 treatment rather than automatically causing the entire rebuilt property to be reassessed as new construction.
When Are California Property Taxes Due?
| Installment | Due Date | Delinquent After |
|---|---|---|
| First installment | November 1 | December 10 |
| Second installment | February 1 | April 10 |
A missed installment generally results in a 10% penalty.
Knowing these dates is important when calculating how much is property tax in California because late-payment penalties can materially increase the cost.
What Happens If You Don’t Pay California Property Tax?
- If a secured tax installment remains unpaid after the delinquency deadline, a 10% penalty generally applies.
- If the property later becomes tax-defaulted, monthly redemption penalties can also accrue.
- A property that remains unredeemed for the statutory period may eventually become eligible for a tax sale.
How to Appeal a California Property Tax Assessment
Homeowners who believe their assessment is too high may be able to file an appeal.
For regular assessments, the filing period generally ends on either:
- September 15, or
- November 30
depending on county procedures.
Supplemental assessments generally have shorter appeal windows, so homeowners should check deadlines immediately after receiving a notice.
Are California Property Taxes Federally Deductible?
Qualifying real property taxes may be deductible if you itemize deductions on your federal tax return. However, not every charge printed on a California property tax bill qualifies.
For tax year 2026, the federal SALT deduction limit covers qualifying state and local income, sales, and property taxes together. This is a combined deduction limit rather than a separate deduction only for California property tax.
Why Did My California Property Tax Bill Increase?
If you previously knew how much is property tax in California for your home but your bill suddenly increased, common reasons include:
- Proposition 13 annual inflation adjustment.
- Recent purchase.
- Other change in ownership.
- New construction.
- ADU addition.
- Supplemental assessment.
- Voter-approved bonds.
- Mello-Roos.
- Parcel taxes.
- Direct assessments.
- Loss of an exemption.
- Recovery from a Proposition 8 reduction.
Compare the current and previous tax bills line by line to determine what changed.
Common California Property Tax Mistakes
Avoid these mistakes when estimating how much is property tax in California:
- Assuming every homeowner pays exactly 1% of current market value.
- Using an effective county rate as the exact rate for a newly purchased home.
- Assuming the seller’s tax bill will remain unchanged.
- Forgetting about supplemental property taxes.
- Ignoring Mello-Roos.
- Assuming Proposition 13 limits the entire bill to a 2% annual increase.
- Thinking the $7,000 Homeowners’ Exemption means a $7,000 tax reduction.
- Assuming all renovations trigger full reassessment.
- Assuming an ADU causes the entire property to be reassessed.
- Missing an assessment appeal deadline.
California Property Tax Checklist for Home Buyers
Before buying a California home, check:
- Expected new assessed value.
- Basic 1% tax estimate.
- Seller’s current tax bill.
- Tax Rate Area.
- Voter-approved bond charges.
- Mello-Roos.
- Parcel taxes.
- Direct assessments.
- Supplemental-tax exposure.
- Homeowners’ Exemption eligibility.
- Planned improvements that may add taxable value.
This checklist provides a more accurate answer to how much is property tax in California for the home you actually plan to buy.
Conclusion
So, how much is property tax in California in 2026?
For a simple estimate, start with 1% of taxable assessed value. Then add applicable voter-approved debt, Mello-Roos, parcel taxes, and other property-specific assessments. The answer to how much is property tax in California can differ greatly from one homeowner to another because Proposition 13 bases taxes largely on assessed value rather than today’s market price. Long-time owners may therefore pay much less than recent buyers of similar homes.
For buyers, the most reliable approach is to estimate the new assessed value after purchase and then check the home’s APN, Tax Rate Area, Mello-Roos, bond charges, direct assessments, and possible supplemental taxes. Existing homeowners should also review the Homeowners’ Exemption, Disabled Veterans’ Exemption, Proposition 8 relief, Proposition 19 benefits, Property Tax Postponement, disaster relief, and assessment-appeal options when applicable.
By understanding these rules, calculations, and local charges, you can get a much more accurate answer to how much is property tax in California instead of relying on a single statewide percentage.
