California Property Tax Deadline April 10, 2026: Penalties, Payment Options, and Exemptions

Last updated: April 2026 | 5 min read

When Are California Property Taxes Due

California property taxes are paid in two installments each fiscal year. The first installment covers July 1 through December 31 and is due November 1, becoming delinquent after December 10. The second installment covers January 1 through June 30 and is due February 1, becoming delinquent after April 10.

For the 2025-2026 fiscal year, the second installment California property tax deadline is April 10, 2026. Since April 10 falls on a Friday this year, there is no weekend extension. Your payment must arrive by 5 p.m. or close of business, whichever is later, at your county tax collector’s office.

If you are wondering when are California property taxes due for both installments, here is the complete annual schedule.

One important detail: not receiving a tax bill does not exempt you from payment or penalties. If you did not receive your bill, contact your county tax collector’s office before the California property tax deadline passes.

What Happens If You Miss the Deadline

Missing the April 10 deadline triggers an automatic 10% penalty on the unpaid second installment, plus a $20 administrative cost per parcel. For example, if your second installment is $3,000, the penalty is $300 plus $20, bringing your total to $3,320.

After June 30, if both installments remain unpaid, the property becomes tax-defaulted. The county places a lien on the property. After five years of tax default, the county initiates the process to sell the property at a tax sale. While a tax sale is rare for occupied homes, the penalties and interest compound quickly.

I’ve talked to homeowners across California who assumed the penalty was a small flat fee. It is not. At 10% of your installment, the cost of missing the deadline in an expensive California county is significant. On a $1.2 million assessed property paying roughly $7,200 per year in property taxes, the second installment penalty alone is $360 plus $20.

How to Pay Your Property Taxes

Now you know the deadlines and what happens if you miss them. The next step is getting your payment in on time. Every California county offers multiple payment methods, and the one you pick affects what you pay in fees.

Online via eCheck is the fastest and cheapest method. Most counties charge no fee for electronic check payments. You will need your bank routing number and account number. Visit your county treasurer-tax collector website to access the payment portal.

Online via credit or debit card is convenient but carries a processing fee, typically 1.99% to 2.34% of the payment amount. On a $3,600 installment, the fee runs $72 to $84. For large payments, eCheck saves you real money.

Payment by mail works if your check is postmarked by April 10. Do not rely on delivery speed. A postmark after April 10 means the penalty applies regardless of when the county receives your check.

In-person payments at your county tax collector’s office must arrive before 5 p.m. on April 10. Some counties also offer secure drop boxes with extended hours. Check your county’s website for specific locations and hours.

I switched to eCheck years ago after dealing with the credit card fee on a large bill. The savings add up, especially when you are making two payments per year. If you are still writing checks and mailing them, the online portal takes about five minutes to set up.

California Property Tax Rates Explained

Once your payment is submitted, you might wonder why your bill is the amount it is. The answer starts with Prop 13 property tax rules, which set the foundation for California’s system. Under Proposition 13, passed in 1978, the base property tax rate is 1% of assessed value. Assessed value increases are capped at 2% per year until a change of ownership or new construction triggers reassessment at current market value.

In practice, most California homeowners pay an effective rate between 1.10% and 1.55% because voter-approved bonds, Mello-Roos community facilities districts, and special assessments add to the 1% base. Despite this, California’s effective property tax rate sits at approximately 0.71% of current market value, ranking 34th out of 50 states. The gap between the assessed rate and effective rate exists because Prop 13 property tax caps keep assessed values well below market values for long-term owners.

Since I’ve owned property in California since the late 1990s, my assessed value is substantially below current market value. This is the core benefit of Prop 13 for long-term residents. However, if you recently purchased a home, your assessed value reflects your purchase price, and your tax bill is higher relative to market value than your neighbor who bought 20 years ago.

Exemptions and Savings You Should Know About

The California property tax exemption homeowners should know about first is the Homeowner’s Exemption. It reduces your assessed value by $7,000, saving approximately $70 per year. File the BOE-266 form with your county assessor after closing on your primary residence. You only need to file once, and the exemption stays in place until you sell or move out.

Veterans have access to additional exemptions. The Disabled Veteran’s Exemption provides a reduction of $161,083 to $241,627 in assessed value, depending on income. Qualifying veterans or their surviving spouses should contact their county assessor for application details.

Seniors age 55 or older benefit from Proposition 19, which allows you to transfer your Prop 13 property tax base to a new home anywhere in California. Before Prop 19, this transfer was limited to certain counties. Now it applies statewide, up to three times in your lifetime, though the new home’s value is adjusted if the replacement property costs more than the original.

These exemptions are worth pursuing. Many homeowners do not realize the California property tax exemption options available to them, and the savings compound over the life of ownership.

Supplemental Property Tax Bills

If you recently purchased a home or completed new construction, you will receive a California supplemental property tax bill. This bill reflects the difference between the previous assessed value and the new assessed value as of the date of the ownership change or completion of construction.

The supplemental bill is separate from your regular annual bill. It is prorated based on the number of months remaining in the fiscal year from the date of the event. For example, if you bought a home in October, your supplemental bill covers October through June of the current fiscal year.

New buyers are often surprised by the California supplemental property tax bill because it arrives outside the normal November billing cycle. It is a one-time adjustment, not a recurring charge. After the supplemental assessment, your regular annual bill will reflect your new assessed value going forward.

Special Relief for Wildfire Survivors

If you were affected by the January 2025 LA wildfires, the state of California extended property tax deadlines and offers penalty cancellation for up to four years. This relief applies to homeowners in declared disaster areas, including Pacific Palisades, Altadena, and surrounding communities.

Check your county treasurer’s website for specific extension dates and the process for requesting penalty cancellation. LA County’s recovery portal at recovery.lacounty.gov has details on all available tax relief for fire survivors.

Pros and Cons of Paying Early vs. Waiting Until Deadline

Final Verdict

The California property tax deadline for the second installment is April 10, 2026. Missing it costs 10% of your installment amount plus $20. For most homeowners, the smartest move is to pay via eCheck online before the deadline. It is free, fast, and you get instant confirmation.

If you have not already filed for the Homeowner’s Exemption, do it today. The $70 annual savings is small, but it is free money you are leaving on the table. Veterans, seniors, and wildfire survivors should also check their eligibility for additional exemptions and deadline extensions.

California’s property tax system runs on strict deadlines with no grace period. The dates are fixed: December 10 and April 10. Mark them, set a reminder, and pay before the penalty kicks in.
