Kern County Tax Collector website, payment center and property search
The Kern County Treasurer-Tax Collector is the county office for property-tax payments, payment status, delinquent secured taxes, redemption bills, tax-defaulted installment plans and tax sales. The public office is at 1115 Truxtun Avenue, 2nd Floor, Bakersfield, CA 93301.
For online property-tax lookup, use the official Kern County payment system and search by property address, ATN, File Number or Bill Number. For mailed tax payments, Kern lists the payment center as KCTTC Payment Center, P.O. Box 541004, Los Angeles, CA 90054-1004.
Choose the right Kern County tax route first
Use the payment search, choose the correct installment, and pay by ACH, card, mail or counter before the delinquency time.
Search previous-year bills, check for a redemption bill, then call for the current payoff before mailing funds.
Owners should ask about redemption. Bidders should research title, access, maps, assessments, IRS lien risk and GovEase terms before bidding.
How to pay Kern County property tax online
The online payment system is useful when you have a current bill, know the property address, or can search with an ATN, File Number or Bill Number. It is also useful for printing a bill or checking whether a recent payment has posted.
Kern County property tax search: address, ATN, File Number or Bill Number?
| Search method | What to enter | Best use | Micro-level fix |
|---|---|---|---|
| Property address | Street number, direction, street name, street type and city when known. | You do not have the bill number or parcel identifiers. | Kern warns that names like California Ave can exist in Bakersfield, Ridgecrest, Shafter and McFarland. Try All Cities when unsure. |
| ATN | At least 6 digits for partial search; all 11 digits for exact match. | Secured and secured supplemental property bills. | Hyphens can be included, removed or replaced with spaces. |
| File Number | All 13 digits. | Unsecured and unsecured supplemental bills. | Partial File Number search is not supported, so copy every digit. |
| Bill Number | At least the first 11 digits; the 12th check digit is not required. | A specific bill, reassigned bill, or bill that does not appear under parent ATN/File Number. | Use Bill Number when the bill moved to a different ATN or File Number during the year. |
Why your Kern County property tax bill is not showing online
Separate street number, direction, name, type and city. Try All Cities if the property could be listed under another Kern community.
Once a secured bill becomes delinquent, Kern says it can be wrapped into one redemption bill with other delinquent bills for the same ATN.
A bill may move to a different ATN or from ATN to File Number during the year. Search directly by Bill Number when that happens.
New county listings may not display yet. Call if the property should exist but the system does not show it.
Some bills cannot be paid online and must be paid by cash, money order, cashier’s check or wire transfer.
Recently paid bills can still show as payable until the end of the following business day.
How to read a Kern County tax bill result before paying
| Label | What it usually means | What to check |
|---|---|---|
| ATN | Assessor Tax Number for secured real property. | Confirm all digits, property address, tax year and installment. |
| File Number | Identifier used for unsecured property tax bills. | Use all 13 digits and confirm whether the bill is current or supplemental. |
| Bill Number | Direct ID for a specific bill. | Use at least the first 11 digits, then verify the bill details. |
| Secured | Regular real-property tax secured by the property. | First installment, second installment or full-year payment. |
| Secured supplemental | Additional tax after reassessment from sale, transfer or new construction. | Do not assume escrow or mortgage servicer paid it. |
| Unsecured | Tax on personal property, business property, boats, aircraft, possessory interests or similar items. | File Number, due date, accepted payment method and appeal route. |
| Redemption bill | A combined delinquent secured-tax account after default. | Current payoff, penalties, costs, fees, interest and accepted funds. |
Kern County property tax payment fees, limits and posting delays
| Payment issue | Official rule signal | Practical decision |
|---|---|---|
| ACH / electronic check | Accepted online and not subject to convenience or processing fees. | Lowest-cost online route when your routing and account numbers are verified. |
| Credit or debit card | 2.19% non-refundable service fee with a $2 minimum. | Useful for speed, but expensive on large bills. |
| Returned payment | $27 returned-payment fee; penalties or interest may apply if returned after a deadline. | Avoid using uncertain bank data near December 10 or April 10. |
| Duplicate transaction | Duplicate returned transactions may each trigger a $27 fee. | Save the first confirmation and wait for posting before paying again. |
| Recently paid bill | Online payments may not be marked paid until the end of the next business day. | Recheck next business day before assuming failure. |
| Cart limit | Up to 12 bills can be paid in one transaction. | Split larger batches into multiple transactions. |
| Large balance | No single-transaction maximum is listed, but ACH or wire can save fees over $25,000. | For large accounts, compare ACH/wire before using a card. |

Kern County Tax Collector payment center and mailing address

Kern County property tax due dates and penalty timeline
You may also pay both secured installments when the first installment is due.
A 10% penalty is added after the delinquency deadline.
Confirm whether your mortgage servicer or escrow account is actually paying it.
A 10% penalty plus a $10 cost is added after the deadline.
Unpaid secured taxes may transfer to the delinquent roll with a $15 redemption fee and 1.5% monthly penalty.
After five years of tax default, property may become eligible for public auction.
Kern County supplemental property tax bills: what new owners miss
A supplemental bill is not just another copy of the annual secured bill. It is tied to a reassessment event, such as a change in ownership or new construction, and the delinquency schedule can depend on when the bill was mailed.
Fiscal year, event date, old value, new value, net supplemental assessment, exemptions and tax due.
Closing prorations are between buyer and seller. They do not automatically change the county bill or make the Tax Collector adjust the installment.
Many supplemental bills go directly to the taxpayer. Do not assume your mortgage company paid it unless you confirm.
Kern County unsecured property taxes: business equipment, boats, aircraft and more
Unsecured tax bills are different from regular real-estate secured bills. They can apply to business equipment, supplies, fixtures, leased equipment, farm equipment, livestock, aircraft, boats, mining claims, possessory interests, oil and gas equipment, pipelines, timber and other personal-property categories.
Use the full 13-digit File Number. Partial File Number searches do not work.
Call the Assessor-Recorder at 661-868-3485 for assessed value, description or address questions.
Unsecured assessment appeal windows are date-sensitive. Do not wait until a collection deadline to ask value questions.
What “Tax Defaulted” means on a Kern County bill
A “Tax Defaulted” notation means the Treasurer-Tax Collector shows delinquent taxes for a prior year. That account can carry penalties, costs, fees and interest, and five years after the first year of delinquency the property may become eligible for sale at public auction.
Back taxes remain a lien on the property. Selling, refinancing or transferring the property does not make old tax debt disappear.
A past notice may be outdated because interest and fees continue. Call for a current payoff.
Some delinquent bills require secure funds and cannot be handled like a normal online installment.
Kern County tax-defaulted installment plan: who should ask and what can go wrong
Kern County publishes an installment-plan route for qualifying tax-defaulted secured property. It is not the same as a normal monthly payment plan, and the online total balance is not necessarily the amount needed to start the plan.
| Requirement | County rule signal | Practical warning |
|---|---|---|
| Current taxes | Current-year taxes must be paid depending on whether the plan starts before November, between November and January, or between February and June. | A plan for old taxes does not excuse current taxes. |
| Processing fee | $100 non-refundable processing fee. | Budget this in addition to the redemption amount. |
| Initial payment | 20% or more of the amount due, plus the processing fee. | Call for the correct start amount. |
| Annual payment | 20% or more of the original redemption amount plus 1.5% monthly interest on unpaid balance by April 10. | Missing annual conditions can default the plan. |
| Power-to-sell status | A new plan may not be initiated after the property has become subject to power to sell. | Do not wait until auction season to ask. |
Kern County Tax Collector auction: owner redemption and bidder due diligence
Kern County’s current tax sale page lists the next sale for September 14-16, 2026, with property listings expected approximately 30 days before the sale on GovEase. The county tax sale brochure also states that Kern does not sell tax lien certificates.
- Call for the current redemption payoff.
- Ask which funds are accepted for your account.
- Redeem before 5:00 p.m. on the last business day before sale.
- Do not rely on an old sale-list amount as final payoff.
- Register through GovEase before bidding.
- Research title, access, parcel maps, legal description and location.
- Check for assessments, bonds, IRS lien risk and local conditions.
- Understand that sales are final and properties are sold as-is.
| Issue | Official/PDF detail | Why it matters |
|---|---|---|
| Bidding platform | Sale takes place online through GovEase. | You need platform access before bidding starts. |
| Registration | Only registered bidders can bid. | Do not wait until the closing hour. |
| Deposit | The tax sale brochure states a $5,000 deposit is required to bid. | You need funds ready before researching like a buyer. |
| Bid increments | County sale page describes raises of at least $100 until sold. | Set a maximum bid before emotions take over. |
| As-is sale | Kern makes no guarantee of title, location or condition. | A cheap parcel can still be a bad buy. |
| Remaining assessments | Some bonds or assessments by other agencies may remain outstanding. | Auction price is not always the full financial exposure. |
| IRS lien risk | IRS may redeem property with a recorded federal lien up to 120 days after sale. | Title and resale assumptions can be wrong. |
| Deed timing | Brochure says deed may be recorded within 60 days after payment and deed information are received. | Possession and insurable title can lag the auction close. |
| Title insurance | County says many title companies may not insure for at least one year after recording. | Financing or resale can be harder than expected. |
Should you call the Kern Tax Collector, Assessor, Auditor or Clerk?
| Your issue | Correct office | Why |
|---|---|---|
| Balance, receipt, payment, redemption, tax-defaulted account or auction | Treasurer-Tax Collector | This office collects taxes and manages payment status, delinquency and tax sales. |
| Value, ownership, exemption, improvement value or bill mailing address | Assessor-Recorder | The Assessor maintains assessed value, ownership and many address/exemption records. |
| Tax rates or agency charges | Auditor-Controller-County Clerk or listed agency | The Tax Collector collects the bill; rate and levy calculations can belong elsewhere. |
| Assessment appeal filing | Clerk of the Board / Assessment Appeals | Assessment appeal windows and forms are separate from payment collection. |
Use for value, ownership, exemptions, improvements, address records and parcel questions. Official secured-tax guidance lists 661-868-3485.
Use for rate or calculation questions when the bill amount is about levy math rather than payment status. Official guidance lists 661-868-3599.
Use for assessment appeal filing questions. Official secured-tax guidance lists 1115 Truxtun Avenue, 5th Floor, Bakersfield.
California Property Tax Postponement is not a Kern County penalty waiver
Kern links to California’s state-level Property Tax Postponement information. The program is administered by the State Controller for qualifying homeowners who meet specific age, disability, equity, residence and income rules.
Homeowners who are seniors, blind or have a disability and may meet the state requirements should review the current filing period and rules early.
Postponement is not automatic, not a tax cancellation, and not a general Kern County fee waiver.
Kern County Tax Collector address map: Bakersfield office
Use the office address for in-person tax questions, counter payments, banking-related tasks or documents the official office tells you to bring. Do not use the Bakersfield office address when the county specifically tells you to mail tax payments to the Los Angeles payment center.
