California Property Tax Deadlines for 2026–2027: When Are Payments Actually Late?
If you own a home in California, you’ve probably heard that property taxes are due twice a year.
But there’s an important distinction that homeowners should understand.
The date your property taxes are due and the date you actually face a late-payment penalty are not the same.
Knowing the difference could help you avoid an unnecessary 10% penalty.
When Are California Property Taxes Due?
For the 2026–2027 property tax year, California’s regular secured property taxes are generally divided into two installments.
| Installment | Due Date | Last Day Without Penalty |
|---|---|---|
| First | November 1, 2026 | December 10, 2026 |
| Second | February 1, 2027 | April 12, 2027 |
The first installment becomes due November 1, but it isn’t considered delinquent until after December 10.
The second installment becomes due February 1, but homeowners have until April 12, 2027, to pay without a delinquency penalty. The normal April 10 deadline falls on a Saturday in 2027, so the deadline moves to the next business day.
What Happens If You Miss the Deadline?
Missing either delinquency deadline generally results in a 10% penalty on the unpaid installment.
For example, if your property tax installment is $5,000, a 10% penalty would add $500 to your bill.
That’s an expensive consequence for missing a deadline, especially when a simple reminder or scheduled payment could have prevented it.
Additional charges may also apply depending on the installment and how long the taxes remain unpaid.
What If Your Property Taxes Are Included in Your Mortgage?
Many California homeowners pay their property taxes through an escrow or impound account.
If that’s how your mortgage is structured, a portion of your monthly mortgage payment is set aside to cover property taxes and often homeowners insurance.
Your mortgage servicer generally handles the property tax payments when they become due.
However, it’s still worth reviewing your mortgage statements and confirming that your taxes have been paid.
This is particularly important if you’ve recently purchased a home, refinanced or changed mortgage servicers.
What About Supplemental Property Tax Bills?
There’s another important distinction for California homeowners.
The regular November and February installment schedule generally applies to annual secured property taxes.
Supplemental property tax bills can have different due dates.
These bills may be issued after a property changes ownership or new construction is completed.
They also aren’t always paid automatically through your mortgage escrow account, so it’s important to review any supplemental bill you receive and confirm who is responsible for paying it.

The Bottom Line for California Homeowners
California property taxes are generally due November 1 and February 1, but homeowners have additional time before late-payment penalties apply.
For the 2026–2027 tax year, the two dates to remember are December 10, 2026, and April 12, 2027.
Whether you pay your taxes directly or through your mortgage company, keeping track of these deadlines can help you avoid unnecessary penalties.
