LA County Tax Collector: Pay Property Tax, Find AIN & Avoid Wrong Portals
Use this guide when you need the real LA County Tax Collector payment route, office phone, bill search, AIN help, mailing address, secured-tax deadlines, unsecured-tax warning, card fee, eCheck details or the right county office for a value or exemption question.

Choose the right LA County route
Quick answer: where do I pay LA County property tax?
Pay Los Angeles County secured property taxes through the official Treasurer and Tax Collector payment route. You normally need your Assessor’s Identification Number, or AIN, to search and pay a secured property tax bill. The in-person secured property tax counter is at 225 North Hill Street, First Floor Lobby, Los Angeles, CA 90012.
Online eCheck is listed with no cost to the taxpayer. Credit/debit card payments are listed with a 2.22% service fee and $1.49 minimum. For a value, exemption, ownership or mailing-address question, use the Los Angeles County Assessor instead of the payment office.

Current source check for 2026 publishing
Los Angeles County property-tax information is active and date-sensitive. The County’s official pages currently confirm the standard secured-tax schedule, online eCheck and card payment options, in-person counter hours, mail instructions, unsecured-tax rules and public inquiry routes.
A fresh County warning from September 2026 also flags property-tax scams promoting a fake federal “1098-SR” form. Do not pay for a promised tax freeze or share personal information with a caller, social video or website unless you verify it through the County Assessor, Treasurer and Tax Collector, Auditor-Controller or another official agency.

Do not confuse LA County with the City of Los Angeles
The City of Los Angeles Office of Finance handles city business-tax and city revenue matters. The Los Angeles County Treasurer and Tax Collector handles county property-tax collection. A property tax bill for a parcel in Los Angeles County should be paid through the County route, not a city business-tax portal.
How to pay LA County property tax
LA County gives taxpayers several payment methods. The safest first step is to start from the official Treasurer and Tax Collector payment page, then confirm the bill, AIN, installment and fee before sending money.
Pay online
Use the official payment link from the TTC site. Online payments are accepted 24 hours a day, 7 days a week, up to 11:59 p.m. Pacific Time on the delinquency date.
Open Payment OptionsPay by mail
Make the check or money order payable to Los Angeles County Tax Collector, write the AIN on the lower left corner, include the payment stub and use the correct mailing address.
Mailing InstructionsPay by phone
Card and debit payments can be made by phone at 888-473-0835. You need the AIN, year and sequence from the secured property tax bill.
Call Phone PaymentPay in person
In-person secured property tax payment is listed at 225 North Hill Street, First Floor Lobby, Los Angeles, CA 90012, Monday through Friday from 8:00 a.m. to 5:00 p.m. Pacific Time, excluding Los Angeles County holidays. The official payment page lists cash, check, money order, cashier’s check and major credit/debit cards at this counter.
Lancaster payment-location caution
The TTC payment page also references a Lancaster location at 335A East Avenue K-6, Lancaster, CA 93535 for Annual Secured Property Tax Bill installment delinquency dates only. It does not accept cash. Do not treat it as a normal everyday full-service tax counter without checking the current TTC page first.

LA County property tax payment fees and limits
Payment method matters because a service fee can become expensive on a large property tax bill. The County says it does not receive or retain the third-party card/debit service fee.
| Payment type | Current official information | Before you submit |
|---|---|---|
| Online eCheck | No cost to the taxpayer is listed for electronic check payments. | Confirm routing/account numbers and that the bank account is ACH-enabled. |
| Online credit/debit card | 2.22% service fee, with a $1.49 minimum per transaction. | Compare the fee before using a card for a large tax bill. |
| Phone card payment | 2.22% service fee, $1.49 minimum; phone payment line is 888-473-0835. | Have AIN, year and sequence ready before calling. |
| In-person card/debit | Card/debit payments are listed at the counter with a transaction limit including service fee. | Check the live TTC page if the bill is large or you need split transactions. |
| Mail check/money order | No card fee, but postmark and wrong-address risks matter. | Mail early, include stub and use the correct P.O. Box. |
| Easy Smart Pay monthly option | TTC says it partnered with ESP, an independent provider, for automated monthly payments. | Review ESP’s separate fees, terms, privacy and support before enrolling. |
Large eCheck limit warning
Official TTC pages have shown different eCheck transaction-limit language in different sections. If you are paying a very large amount, verify the current limit inside the live payment system before assuming one published number controls your transaction.
LA County secured property tax due dates
Annual secured property tax bills are mailed each fiscal tax year and have two payment stubs. The regular secured-tax calendar is simple, but penalties can still happen when taxpayers confuse due dates, delinquency dates, mail postmarks or supplemental bills.
| Installment | Due date | Delinquent if not paid by | What to remember |
|---|---|---|---|
| First secured installment | November 1 | Close of business on December 10 | Pay early if mailing. Online payment is accepted until 11:59 p.m. PT on the delinquency date. |
| Second secured installment | February 1 | Close of business on April 10 | The second installment can include a statutory cost in addition to penalty if late. |
| Weekend or County holiday | Depends on the year | Extended to the next business day under the County’s published rule | Always check the bill or TTC page for the exact tax year. |
| Supplemental or adjusted bill | Printed on that bill | Printed on that bill | Do not force annual secured dates onto a supplemental bill. |
2026–27 practical timing
The 2026–27 fiscal tax year runs July 1, 2026 through June 30, 2027. LA County’s standard secured-tax framework means the first installment becomes due on November 1 and the second on February 1, but your actual bill and the official TTC portal should control the amount, year, sequence and any special notice.
AIN lookup, PIN, property tax bill search and payment history
The AIN, or Assessor’s Identification Number, is the key number for secured LA County property tax tasks. It is a 10-digit number assigned by the Office of the Assessor to each piece of real property and appears on the secured property tax bill.
Which number do you need?

Open Payment SystemUnsecured property taxes in LA County
Unsecured property taxes are different from secured real-property taxes. They can apply to items such as business personal property, boats, aircraft and other assessments that are not liens against real property.
| Unsecured tax issue | Official rule or route | Practical warning |
|---|---|---|
| Annual unsecured due date | Due upon receipt and delinquent after 5:00 p.m. PT on August 31. | Weekend or County holiday rules can move the cutoff to the next business day. |
| Late unsecured bill | 10% penalty plus Notice of Enforcement cost can apply after the delinquency date. | Additional lien cost and monthly penalties can follow if unpaid. |
| Online unsecured payment | Current-year unsecured payments may be paid online by eCheck or card/debit. | Delinquent unsecured bills may require contacting the Unsecured Property Tax Section. |
| Mail unsecured payment | Los Angeles County Tax Collector, P.O. Box 54027, Los Angeles, CA 90054-0027. | Use the roll year and bill number so the payment posts to the correct bill. |
| Business, boat or plane sold | Unsecured taxes are tied to ownership on the January 1 lien date. | Do not assume selling the property later automatically removes the bill. |
Do not mail unsecured payments to the secured-tax P.O. Box
Secured and unsecured tax payment mail addresses are not the same. If your bill says unsecured, use the address and roll-year/bill-number instructions printed for that bill.
LA County Tax Collector vs Assessor vs Auditor vs Appeals Board
Los Angeles County property tax involves multiple official offices. Sending the right question to the wrong office creates delays and can make a deadline problem worse.
| Your question | Correct office | Why |
|---|---|---|
| How much do I owe, did my payment post, where is my receipt? | Treasurer and Tax Collector | TTC bills and collects property tax payments. |
| Why did my assessed value, ownership or exemption change? | Los Angeles County Assessor | The Assessor establishes assessed value and administers many exemptions and ownership records. |
| Why is this direct assessment, special charge or tax rate on my bill? | Auditor-Controller or listed agency | The Auditor-Controller applies rates and direct assessments to create the tax amount. |
| How do I appeal assessed value? | Assessment Appeals Board | The Appeals Board handles formal assessment disputes. |
| Is this a City of LA business tax issue? | City of Los Angeles Office of Finance | City business taxes are not the same as county property tax payments. |
| Is this federal income tax? | IRS | Federal tax issues do not belong to the County Tax Collector. |
Homeowners’ Exemption and mailing-address changes
Homeowners’ Exemption, property value, ownership data and many mailing-address changes belong with the Assessor, not the payment counter. The Property Tax Portal links those tasks under Assessor-related tools.
Late, delinquent and tax-defaulted LA County property taxes
If a secured tax installment is not paid by the delinquency date, penalties can apply. If secured taxes remain unpaid after the fiscal-year end, the account can become tax-defaulted and additional redemption penalties, fees and costs can apply.
Late first installment
The first installment is due November 1 and becomes delinquent after December 10. Search the live account for the updated amount before paying late.
Late second installment
The second installment is due February 1 and becomes delinquent after April 10. The second installment can include cost as well as penalty if late.
Defaulted property
Tax-defaulted property can move into redemption and sale procedures. Use official TTC auction/redemption resources and do not rely on generic calculators.
LA County does not sell tax lien certificates
The LA County Property Tax Portal says Los Angeles County does not sell Certificates of Tax Liens, and no other California county does so at this time. Be careful with websites that present California county tax collection as a tax-lien certificate purchase opportunity.
Wildfire, disaster and penalty-cancellation guidance
Some Los Angeles County taxpayers have special property-tax questions because of wildfire or other disaster impacts. These situations are not the same as the normal secured-property tax calendar.
Fire-impacted property
LA County emergency guidance explains that a Misfortune and Calamity claim can request reassessment for damaged or destroyed property and may affect property-tax timing for eligible taxpayers who pay the Tax Collector directly.
Wildfire & Emergency FAQPenalty cancellation
Penalty cancellation is account-specific and documentation-based. Use the official TTC request route instead of paying a private “tax relief” promoter.
Penalty Cancellation Request2026 scam warning: fake property-tax relief claims
County officials warned property owners about scams promoting a nonexistent federal form that allegedly freezes or reduces property taxes. Real California property-tax relief programs should be verified through official County or State sources before you provide personal information or pay anyone.
New property owners, escrow and duplicate-payment checks
New owners often receive confusing tax mail because ownership records, escrow payments and bill mailing can move on different schedules. If a lender, escrow company or prior owner was involved, verify payment status before making a second payment.
- Check the closing statement for property tax payments made through escrow.
- Use the official payment history or bill search route before paying again.
- Ask your lender if taxes are paid through an impound or escrow account.
- Use the Assessor route for ownership or mailing-address changes.
- Keep receipts, escrow statement pages and any confirmation numbers.
Duplicate-payment prevention
If a payment appears missing, do not instantly submit another large payment. Check bank records, the County payment history, the payment date, the payment method and the official inquiry route first.
Common LA County Tax Collector problems
| Problem | Likely cause | Best next step |
|---|---|---|
| Cannot find the property tax bill | Wrong AIN, address variation, current-year timing or wrong portal. | Use the Assessor Portal for AIN lookup, then the TTC payment route. |
| Payment page asks for a PIN | The payment system may need the PIN printed on the bill. | Use official bill copy/inquiry options if the original bill is missing. |
| Credit-card fee looks high | LA County card/debit payments use a percentage-based service fee. | Compare eCheck, mail or in-person options before submitting. |
| Bank bill pay has no postmark | Bank online bill pay may send a paper check in a way that does not receive a USPS postmark. | Avoid bank bill pay near a deadline; use official online payment or mail early. |
| Value or exemption is wrong | The issue belongs with the Assessor, not the Tax Collector. | Use Assessor tools for value, ownership, exemptions or mailing address. |
| Unsecured bill is delinquent | Unsecured bills have their own roll year, bill number, PIN and delinquency rules. | Call 213-893-7935 or use the Unsecured Public Inquiries route. |
| Tax-defaulted property notice received | The account may have moved beyond current-year collection. | Use official TTC defaulted-property/redemption resources; get a current payoff. |
