Got a Property Tax Bill in the Mail? Read This Before You Pay It
A property tax bill can be an informational copy, a regular bill your escrow account pays, or a supplemental bill that needs your attention. Here is how to tell the difference.
Quick answer
Receiving a property tax bill does not always mean you should pay it. If you have an escrow account, your mortgage servicer normally pays the regular annual bill, while a California supplemental bill is generally separate and should be reviewed promptly unless your servicer confirms it will be paid.
Every fall, property tax bills start showing up in the mail, and every fall my phone starts ringing with the same question: "Carlos, aren't my taxes included in my mortgage payment?"
If you have had that same thought, you are not alone. In most cases, the answer is yes, and the bill in your hand is just a copy. But there is one bill you should never ignore. Let me walk you through how to tell which one you have.
How your escrow, or impound, account works
If your loan has an escrow account, also called an impound account in California, your monthly payment is more than principal and interest. A portion goes into a separate account that your mortgage servicer uses to pay your property taxes and homeowners insurance when they come due.
It works like this:
- Each month, part of your payment is set aside for taxes and insurance.
- When the county tax bill or insurance premium is due, the servicer pays it directly from that account.
- Once a year, the servicer reviews the account in an escrow analysis and adjusts your payment up or down if taxes or insurance changed.
Not sure if you have escrow? Check your monthly mortgage statement. If you see a line for "escrow" or "taxes and insurance," you are covered for regular bills.
Why you got a bill you do not have to pay
The county mails a copy of the annual tax bill to the property owner, even when a lender or servicer is paying it. Receiving a copy does not mean you need to pay it again.
Look near the bottom of the bill. Many counties print a note such as "For Informational Purposes Only" or "Memo Copy Only." That is your signal that it is a courtesy copy.
Do not toss it. Keep it with your important papers, because your tax preparer may want it. Property taxes you pay on your home may be deductible, and the paid amount is also shown on the year-end Form 1098 from your servicer.
The one bill you should never ignore: the supplemental tax bill
A supplemental tax bill is usually not paid through your escrow account. If your bill says "Supplemental," assume it is yours to pay unless your servicer confirms otherwise.
Why does this happen? In California, when you buy a home or finish new construction, the county reassesses the property at its new value. Your regular tax bill may still be based on the previous owner's lower value. The supplemental bill covers the difference, prorated from the date you took ownership to the end of the tax year.
For a deeper explanation of how a California supplemental tax bill is calculated and why it is usually separate from your regular escrow payment, read our supplemental tax guide.
A few things to know:
- It can arrive several months, sometimes up to a year or more, after you close.
- You may receive more than one, depending on when you closed.
- It has its own due dates, separate from the regular bill.
- Late payments carry penalties, so do not set it aside.
If your new value is lower than the prior assessment, you may receive a refund instead of a bill.
What about that homeowners insurance bill?
The same logic applies to insurance. About 30 to 60 days before your policy renews, your insurance company sends a renewal notice. If insurance is part of your escrow, that notice is usually a copy, and your servicer pays the premium.
Two things are worth a quick check:
- The premium went up. Your servicer will pay the new amount, but your monthly payment may rise at the next escrow analysis. That is normal.
- You switched insurance companies. Send the new policy declarations page to your servicer right away. Otherwise, the servicer may keep paying the old company or buy a costly force-placed policy on your behalf.
If your notice says "Amount Due" and you are not sure who is paying, call your servicer before the due date.
No escrow account? Mark these dates
If you do not have an escrow account, you pay your property taxes directly to the county. California's regular secured tax bill is split into two installments:
| Installment | Due | Late after | Late penalty |
|---|---|---|---|
| First | November 1 | December 10 | 10% |
| Second | February 1 | April 10 | 10% plus a $10 cost |
If a late date falls on a weekend or holiday, the deadline moves to the next business day. Most counties let you pay online, by mail, or in person. Supplemental bills have their own due dates printed on the bill.
While you are at it, check your exemptions
While you have the bill in hand, look for a line showing a "Homeowners' Exemption." If it is missing and the home is your primary residence, you may be paying more than you need to.
- Homeowners' Exemption. This reduces your home's assessed value by $7,000, saving roughly $70 or more per year. File once with your county assessor and it stays in place while you live there.
- Disabled Veterans' Exemption. Veterans with a qualifying service-connected disability may be eligible for a much larger reduction. A major expansion under SB 296 begins with the January 1, 2027 lien date. Read our practical SB 296 guide for the eligibility, value cap, and county-assessor claim steps. As a Marine Corps veteran myself, I always encourage fellow veterans to check with their county assessor.
New owners often receive the exemption claim form in the mail after closing. If you did not, your county assessor's website should have it.
Your 60-second bill checklist
When a tax or insurance bill arrives, ask yourself:
- Do I have an escrow account? Check your mortgage statement.
- Does the bill say "Informational" or "Memo Copy"? File it for your tax preparer. No payment needed.
- Does it say "Supplemental"? Plan to pay it yourself, or confirm with your servicer.
- Is it an insurance renewal? Confirm your servicer has your current policy.
- Still unsure? Ask before the due date, not after.
Not sure which bill you received?
A quick question now can save you a lot of worry. Schedule a conversation with Carlos and we can review what the bill says and help you determine whether you need to confirm payment with your mortgage servicer.
