Los Angeles County Property Tax Due Dates 2026-27: Dec. 10, April 12, and How to Pay the Tax Collector

Every home in the City of Los Angeles gets its property tax bill from the Los Angeles County Treasurer and Tax Collector (TTC), which mailed about 2.4 million annual secured bills for 2026-27 by November 1, 2026 [1]. Not getting a bill doesn’t excuse a late payment, so if yours hasn’t arrived, look it up at propertytax.lacounty.gov [1].

The 2026-27 deadlines

The bill has two payment stubs, one per installment [1].

• First installment: due Sunday, November 1, 2026; delinquent after close of business on Thursday, December 10, 2026 [1].
• Second installment: due Monday, February 1, 2027; delinquent after close of business on Monday, April 12, 2027. April 10 falls on a Saturday in 2027, so the TTC moves the deadline to the next business day, as state law requires [1].

Online payments are accepted until 11:59 p.m. Pacific Time on the delinquency date [1]. A payment counts as on time if the TTC receives it, or the U.S. Postal Service postmarks it, by the delinquency date [1].

What a late payment costs here

The TTC adds a 10% penalty to each late installment, plus a $10 cost on a late second installment [1]. Its own example: on a $2,000 first installment, the penalty is $200; on a $2,000 second installment, it’s $210 [3].

If you can’t pay a whole installment, the TTC still recommends paying in full but accepts partial payments, which lower the penalty [1]. For what happens if taxes stay unpaid after June 30 and the statewide rules on tax default, see BestCalifornia’s California property tax due dates and late penalties.

Ways to pay the TTC, and what each costs

A few local details that trip people up [1][2]:

• eCheck needs your AIN. The AIN is on your bill. Phone payments also ask for the bill’s Year and Sequence.
• Bank debit blocks. If your account blocks unknown ACH debits, tell your bank to allow Los Angeles County’s Company Identification Number, 0000079161.
• Check that it went through. Online payments send an email confirmation right away, but a wrong account number can leave the payment incomplete. The TTC suggests confirming with your bank.
• Mail only to P.O. Box 54018. Don’t send cash, and don’t staple or tape anything to the stub.

Monthly payments, Four-Pay and Five-Pay

Automated monthly payments. The TTC has partnered with an independent platform that lets owners spread property tax payments into monthly amounts; paying from a bank account costs nothing, and cards cost 1.99% [1]. The delinquency dates still apply to each installment.

Four-Pay Plan (escape assessments). An escaped assessment for prior years can be paid over four years without penalty if the extra tax is over $500 and you start the plan before that bill’s delinquency date [3].

Five-Pay Plan (defaulted taxes). Owners with defaulted taxes can pay them over five years. It’s open to residential and agricultural property less than five years in default (and vacant residential lots and commercial property less than three years in default), and opening a plan stops the property from being sold at auction [3]. Apply on the TTC’s installment plans page.

Penalty cancellations: what the county says it will deny

State law lets the Tax Collector cancel penalties only in limited circumstances. The TTC lists requests it will deny [4]:

1. A good payment history.
2. A bank bill-pay or online bill-pay payment started before the deadline that arrived after it.
3. A postage-meter date on the envelope (it isn’t a USPS postmark).
4. Saying you mailed it early enough for the post office to deliver it in time.
5. Money problems that kept you from paying.
6. Not receiving a bill.
7. Being a new owner who didn’t understand the process.

If you have a reason the law does allow, file the online Penalty Cancellation Request on ttc.lacounty.gov and send supporting documents to penalty@ttc.lacounty.gov, with sensitive personal information blacked out [4].

Help for older owners and families

• Third-Party Notification: name a friend, relative or agency to get copies of past-due notices. They aren’t responsible for the bill, but they can remind you [1].
• Email reminders: sign up for deadline notices at ttc.lacounty.gov/eNotify [1].
• Property Tax Postponement: the State Controller’s program lets eligible seniors, blind or disabled homeowners postpone current-year taxes on their home. Applications are taken October 1 to February 10; call 1(800) 952-5661 [2].
• Trouble with the mortgage: the county Department of Consumer and Business Affairs’ Foreclosure Prevention Unit gives free counseling [2].
