How to pay an LA County secured property tax bill online
LA County property tax payment methods, fees and limits
No county fee is listed for eCheck. Confirm that your bank account can accept ACH debits before submitting.
Credit/debit card payments list a 2.22% service fee with a $1.49 minimum and online transaction limits.
Call 888-473-0835 and have AIN, Year and Sequence ready.
The 225 N. Hill Street counter accepts common payment methods during published hours; card limits and fees still apply.

How to check LA County property tax payment history
Payment history is a separate service from making a new payment. Use it when you need to confirm a posting, compare escrow activity, print a record or research a possible duplicate payment.
Payment not showing, returned or applied to the wrong bill?
Do not pay again immediately. Save confirmation, bank/card record, amount, date, AIN and tax year, then check official payment history after processing.
An online confirmation does not always mean the payment fully settled. Bank rejections, debit blocks and wrong account details can create a returned payment.
Contact Public Inquiries with the intended and entered details. Do not send a second payment until the county gives a clear next step.
Ask the lender for the payment date, amount, check/trace number, AIN and tax year, then compare the county history.
