Find the AIN, Then Use the Right LA County Office

Los Angeles County property-tax records are split across several official departments. Start with the Assessor Portal to find the property by address or 10-digit AIN/APN, review assessed value and parcel details, and save that identifier before moving to the tax or appeal system.

This 2026 guide separates Assessor records from Tax Collector bills, explains Proposition 13 and supplemental assessments, shows the currently open 2026 assessment-appeal window, provides verified phone numbers, and routes deed or lien research to the Registrar-Recorder instead of the wrong property portal.

Fast Answer: Assessor or Property Tax Collector?

VALUE

County Assessor

Use for assessed value, AIN/APN, property characteristics, change in ownership, new construction, exemptions, Proposition 8 and Proposition 19 questions.

BILL

Treasurer & Tax Collector

Use for the tax bill, amount due, payment, payment history, penalties, delinquent taxes and duplicate bills.

APPEAL

Assessment Appeals Board

Use for a formal challenge to assessed value after determining the correct filing period for the assessment type.

DEED

Registrar-Recorder

Use for deeds, liens, mortgages and other recorded real-estate documents. The Assessor Portal is not a title-search system.

Independent guide: AssessorPropertySearch.org is not Los Angeles County or any county department. Do not send this website tax payments, appeal applications, banking information, deeds or exemption documents.

AIN vs APN: Los Angeles County Parcel Number Explained

AIN means Assessor’s Identification Number. Many property owners and real-estate professionals use the term APN, Assessor’s Parcel Number. In Los Angeles County property-tax research, the same 10-digit parcel identifier is commonly referenced with both terms.

First 4 digits

Map Book

Example: 1234

Next 3 digits

Map Page

Example: 567

Last 3 digits

Parcel

Example: 890

Where to find the AIN: it appears on Los Angeles County annual and supplemental property tax bills. You can also find it by searching the Assessor Portal by property address.
Save it once: the AIN is used repeatedly for tax payment, payment-history search, duplicate bills, assessment appeals and parcel research.

Los Angeles AIN Formatter

If you copied a 10-digit AIN without hyphens, this helper formats it into the familiar 1234-567-890 pattern. It does not search or transmit the number.

Enter exactly 10 digits.

This helper only formats the number in your browser. Verify the parcel on the official Assessor Portal.

Basic Search, Legal Search or Map Search?

Basic Search

Use when: you have a normal street address or AIN.

This is the best starting point for most homeowners, buyers and tax-bill users.

Legal Search

Use when: your research depends on assessment-map or legal-description information rather than a conventional postal address.

Map Search

Use when: you need parcel-location context, nearby parcels or an assessment map rather than only a text result.

Parcel map ≠ boundary survey. An Assessor map is useful for tax and parcel identification but should not be used alone to establish an exact fence, easement, encroachment or legal boundary.

What “2026 Current Roll” Means

Los Angeles County closes an annual assessment roll that the Auditor-Controller and Tax Collector use in the property-tax process. Current Assessor records show 2026 roll entries with records updated in July 2026.

Assessment roll vs tax bill: seeing a 2026 assessment in the Assessor system does not mean the 2026–27 annual secured tax bill has already been mailed. The annual bill is normally mailed in the fall.

Assessor record

Shows valuation and parcel information used in the property-tax process.

Tax Collector bill

Shows the actual taxes, direct assessments, installment amounts, delinquency dates and payment information.

Proposition 13: Why Assessed Value Is Not Current Market Value

California Proposition 13 generally establishes a base-year value when property changes ownership or when qualifying new construction occurs. That base can then receive an annual inflation adjustment generally limited to no more than 2%.

Base-year value

A qualifying change in ownership normally establishes a new assessed base at current market value as of the transfer date.

Annual adjustment

The factored base-year value can generally increase by the applicable inflation factor, capped at 2% annually.

New construction

Qualifying new construction can create a new base-year value for the newly constructed portion while existing components retain their applicable base-year treatment.

Common mistake: Proposition 13 does not mean your total property-tax bill can never rise by more than 2%. Voter-approved debt, direct assessments, supplemental assessments and other bill components can change separately.
General tax levy: the regular county property-tax bill identifies a general levy of 1% of net taxable value, with other voter-approved or direct charges potentially added.

Proposition 8 Decline in Value: When Market Value Falls Below the Prop 13 Value

If a property’s market value as of January 1 falls below its factored Prop 13 base-year value, California’s decline-in-value rules can allow the lower market value to be used temporarily.

Temporary reduction: a Proposition 8 assessment is not a permanent replacement of the Prop 13 base-year value. The Assessor reviews it as market conditions change.
The 2% misconception: while recovering from a temporary decline-in-value assessment, the assessed value can rise by more than 2% in one year until it reaches the factored Prop 13 value. The 2% cap applies to growth of the factored base-year value—not to recovery of a temporary Prop 8 market-value assessment.

Los Angeles Supplemental Property Tax Assessment

A supplemental assessment is separate from the regular annual assessment and commonly follows a qualifying change in ownership or completion of new construction.

A reassessment event occurs

A purchase, other qualifying ownership change or taxable new construction triggers reassessment of the affected interest or improvement.

The Assessor determines the new value

The supplemental assessment generally represents the difference between the newly assessed value and the prior assessed value for the affected event.

The amount is prorated

Supplemental tax reflects the portion of the fiscal year remaining after the reassessment date.

One or two supplemental bills may follow

If the ownership change or completion of new construction occurs from January 1 through May 31, California’s supplemental system can create two supplemental assessments/bills covering two fiscal-year periods.

Pay it separately from the annual bill

Supplemental taxes are additional to the annual secured bill and use the due dates printed on the supplemental bill.

Escrow warning for new owners: Los Angeles County states that supplemental bills are generally mailed directly to the property owner and are generally not paid from the lender’s impound/escrow account. Confirm with your lender rather than assuming escrow will pay it.
Timing: the county warns new owners that supplemental bills can arrive roughly three months to one year after acquisition.

New Los Angeles County Homeowner Checklist

  • Search the property by address in the Assessor Portal.
  • Save the 10-digit AIN/APN.
  • Confirm the deed was recorded through the Registrar-Recorder/County Clerk.
  • Review the new assessed/base-year value after the transfer is processed.
  • Watch for a supplemental assessment or tax bill.
  • Do not assume the mortgage escrow account will pay supplemental taxes.
  • Remember that the first annual tax bill after a purchase may still show the previous owner’s name.
  • File the Homeowners’ Exemption claim if the property is your qualifying principal residence.
  • Use the Tax Collector website to monitor payment status.
  • Save every Notice of Assessed Value Change because appeal deadlines can run from its mailing date.

Los Angeles County Homeowners’ Exemption

The California Homeowners’ Exemption can reduce the taxable value of a qualifying owner-occupied principal residence by up to $7,000.

Principal residence

The home must qualify as the owner’s principal place of residence under the applicable lien-date rule.

January 1

The regular annual exemption framework uses January 1 as the lien date for determining principal-residence qualification.

One-time filing

Once properly granted, the regular Homeowners’ Exemption generally remains until title, occupancy or eligibility changes.

Full annual exemption deadline: a first-time claimant generally files by February 15 to receive the full exemption for that year. That full 2026 deadline has passed as of August 12, 2026, so a late/new owner should use the current Assessor instructions for the relief still available for the applicable assessment or supplemental bill.
New purchase: California also has rules that can allow a qualifying Homeowners’ Exemption to apply to a supplemental assessment when the purchased property was not already receiving the exemption.

Los Angeles Property Tax Assessment Appeal: 2026 Deadlines

Do not use one appeal deadline for every type of assessment. Los Angeles County has different windows for regular, supplemental, adjusted/escape and calamity assessments.

Assessment type

2026 Regular Assessment
July 2–November 30, 2026
Current AAB filing calendar.
Supplemental Assessment
Within 60 days of the mailing date printed on the supplemental notice/tax bill or its postmark date, whichever is later.
Save the actual notice/bill and envelope.
Adjusted / Roll Change / Escape
Generally within 60 days of the applicable notice/bill mailing date or postmark, whichever is later.
Use the specific notice.
Misfortune & Calamity Reassessment

Use the calamity reassessment notice.
Current status: the 2026 regular-assessment appeal period is open now and the county’s online AAB system states that it closes November 30, 2026 at 12 midnight Pacific Time.
Weekend/holiday rule: the AAB states that if the final filing date falls on a Saturday, Sunday or legal holiday, a properly mailed application postmarked on the next business day can be considered timely under its rule. Do not rely on that exception when you can file before the stated deadline.

AAB-100 Assessment Appeal Application: What the 2026 Form Requires

The current Los Angeles County AAB-100 is more detailed than simply entering a parcel number and saying the value is too high.

Property and applicant information

  • Applicant / assessee information.
  • Agent information and authorization when applicable.
  • Assessor’s parcel number / AIN.
  • Property address.
  • Assessment or tax-bill identification.
  • Property type.

Value and appeal information

  • Value shown on the assessment roll.
  • Your opinion of value.
  • Assessment type being appealed.
  • Reason for the appeal.
  • Signature and certification.
  • Applicable filing fee or fee-waiver submission.
Do not leave your opinion of value blank. The current form instructions say the applicant’s opinion of value is required and an incomplete application can be rejected.
Do not attach your hearing evidence to the initial AAB-100 merely because you have it ready. The current paper form specifically tells applicants not to attach hearing evidence to the application; evidence is presented as required in the appeal/hearing process.
Filing fee: Los Angeles County currently charges a $46 non-refundable filing fee per assessment appeal application. Qualifying taxpayers can request a fee waiver by submitting the required waiver material with the application.
An appeal does not stop the tax deadline. The AAB-100 instructions state that filing an assessment appeal does not relieve the taxpayer of the obligation to pay property taxes by the tax bill’s due dates.

Prepare Evidence Before Your LA County Assessment Appeal Hearing

The application starts the appeal; evidence supports the value you are asking the Board to adopt.

For a value dispute

  • Save the Assessor parcel record.
  • Save the assessment notice or tax bill that controls the appeal.
  • Identify the valuation date that applies.
  • Gather comparable sales relevant to that date.
  • Explain location, size, condition and property-type differences.
  • Document material condition issues with dated photos.

For a factual or event dispute

  • Recorded deed or transfer documents.
  • Construction completion evidence or permits.
  • Floor area / property-characteristic evidence.
  • Exemption documentation when relevant.
  • Prior assessment and current assessment comparison.
  • A short explanation of exactly what should change.
Possible hearing officer: the current AAB-100 allows qualifying smaller residential matters and certain properties assessed at $5 million or less to request a hearing officer instead of a three-member Board hearing, subject to the program rules.
Appeal result can move either way: the Assessment Appeals Board is independent of the Assessor and can decrease the assessment, leave it unchanged or increase it based on the evidence.

Los Angeles County 2026–27 Secured Property Tax Calendar

As of August 12, 2026, the next annual secured bill is still ahead of the normal fall mailing cycle.

October 2026 — annual bills normally mailed

Los Angeles County says annual secured bills are mailed on or before November 1.

November 1, 2026 — first installment due

The first installment becomes payable under the regular secured property-tax cycle.

December 10, 2026 — first installment delinquency date

If payment is not received or properly USPS-postmarked by the deadline, the county imposes a 10% penalty.

February 1, 2027 — second installment due

The second half becomes due under the regular annual secured-bill schedule.

April 10, 2027 — regular second delinquency date

The statutory calendar uses April 10. Because April 10, 2027 falls on a Saturday, follow the Tax Collector’s weekend/holiday rule and the exact deadline shown on the 2026–27 bill before relying on a mailed or electronic payment date.

No bill by November 1? Do not wait until December to investigate. Use the AIN to check the account or request a duplicate bill. Not receiving a paper bill does not automatically cancel the tax obligation.

Check Los Angeles Property Tax Payment History

LA County provides a self-service property-tax payment history option. The county indicates that payment history for the past three fiscal tax years can be accessed with the AIN.

Use payment history when

  • You need to confirm a recent annual tax payment.
  • You are checking whether escrow payment posted.
  • You need prior-year payment information.
  • You are comparing tax records before a purchase.

Do not use Assessor history instead

Assessment history shows property values and roll events. It does not prove that the Tax Collector received a specific tax payment.

What Happens When Los Angeles Property Taxes Are Late?

First installment

After the first delinquency deadline, a 10% penalty applies to the unpaid first installment.

Second installment

After the second delinquency deadline, the county applies a 10% penalty plus a $10 cost to the unpaid second installment.

Defaulted taxes

If secured taxes remain unpaid after June 30, additional default/redemption consequences and charges apply beginning July 1.

Do not ask the Assessment Appeals Board to remove a Tax Collector late-payment penalty. AAB-100 instructions distinguish assessment disputes from penalties imposed by the Tax Collector.
Need an exact delinquent payoff? Use the live Tax Collector account or contact the office. Penalties and redemption charges depend on the actual account history and payment date.

Los Angeles Property Records: Deeds, Liens and Recorded Documents

Recorded real-estate documents are maintained by the Los Angeles County Registrar-Recorder/County Clerk, not the Assessor or Tax Collector.

Question
Correct source
What is the property’s assessed value?
County Assessor
How much property tax is due?
Treasurer & Tax Collector
What deed was recorded?
Registrar-Recorder/County Clerk
Is a mortgage or lien recorded?
Registrar-Recorder/County Clerk records

Recorded documents/title research, not merely an Assessor display
Important LA County access rule: the Registrar-Recorder states that it does not provide online internet access to its real-estate record indexes. Members of the public can search/request real-estate records, but the official access process uses online copy request, in-person viewing/request, fax or mail depending on the task.

How to move from an address to a recorded deed

Find the Assessor parcel first

Save the AIN, property address and any available legal-description or transaction clues.

Identify likely party names and recording period

Closing paperwork, title reports and the Assessor’s assessment history can help narrow the document you need.

Use the Registrar-Recorder request/viewing process

LA County real-estate indexes are maintained by name and recording year. Telephone index-search requests are not accepted.

Request the correct copy if needed

Recorded real-estate documents from 1850 forward are available through the office’s applicable copy-request channels.

LA County Homeowner e-Notification for Recorded Documents

Los Angeles County’s Homeowner Notification Program can alert participating homeowners when certain documents affecting their property are recorded.

Useful fraud-monitoring step: the Registrar-Recorder says the program can send paper notices and offers an e-Notification option for faster alerts when qualifying property documents are recorded.
An alert is not title insurance. It helps you learn about a recording; it does not determine whether a document is legally valid or resolve a disputed ownership claim.

Los Angeles Property Tax Assessor FAQs

What is the official Los Angeles property tax assessor portal?

The official Los Angeles County Assessor Portal is the county property-search system for an Assessor’s Identification Number or property address. Use it for assessed value, parcel information and assessment history; use the Treasurer and Tax Collector for the actual tax bill and payment.

What is an AIN or APN in Los Angeles County?

AIN means Assessor’s Identification Number, while APN is commonly used for Assessor’s Parcel Number. Los Angeles County uses a 10-digit property identifier arranged as a four-digit Map Book number, three-digit Page number and three-digit Parcel number, such as 1234-567-890.

Can I search Los Angeles County property records by address?

Yes. Use the official Assessor Portal and search by property address. If the complete address does not match, simplify it by removing unit, city, ZIP code, direction or street suffix, then save the AIN from the correct parcel.

What is the Los Angeles County Assessor phone number?

The Los Angeles County Assessor’s main public-service phone is 213-974-3211. The county also provides the toll-free property-tax assistance number 888-807-2111. Use the Assessor for assessed value, parcel data, exemptions and reassessment questions.

What is the Los Angeles County property tax collector phone number?

The Los Angeles County Treasurer and Tax Collector can be reached at 213-974-2111 or through the toll-free county property-tax number 888-807-2111. Use this office for tax bills, balances, payments, payment status and delinquent-tax questions.

What is the 2026 Los Angeles County property assessment appeal deadline?

The 2026 regular-assessment appeal period is July 2 through November 30, 2026. Supplemental and certain adjusted or escape assessments generally use a separate 60-day filing period based on the mailing date or postmark of the applicable notice or tax bill.

Do I still have to pay my Los Angeles property tax while appealing the assessment?

Yes. The current Los Angeles County AAB-100 instructions state that filing an assessment appeal does not relieve the taxpayer of the obligation to pay property taxes by the tax bill’s due dates. Paying the tax does not prevent you from continuing the assessment appeal.

Why did I receive a supplemental property tax bill after buying a Los Angeles County home?

A qualifying change in ownership generally causes reassessment and can create a supplemental assessment for the difference between the new and prior assessed values. Supplemental bills are separate from the annual bill, and Los Angeles County warns that they generally are not paid from mortgage impound accounts.

When are Los Angeles County secured property taxes due?

Under the regular annual secured-tax schedule, the first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10, subject to applicable weekend and holiday rules.

Where can I search Los Angeles County deeds and liens?

Use the Los Angeles County Registrar-Recorder/County Clerk for deeds, liens, mortgages and other recorded real-estate documents. The office does not provide its real-estate indexes for public internet searching, so use its official viewing or record-copy request process.

One Parcel Number Makes the LA County Property Tax System Easier

Start with the Los Angeles County Assessor Portal, find the property by address and save the 10-digit AIN/APN. That identifier is the bridge to tax bills, payments, assessment appeals and many other county property services.

Use the Assessor for value, the Treasurer and Tax Collector for money due, the Assessment Appeals Board for formal value disputes, and the Registrar-Recorder/County Clerk for recorded legal documents. Keeping those four roles separate prevents most Los Angeles property-tax search mistakes.
