Merced County Tax Collector Office, Phone and Hours
Use the Tax Collector phone line for tax payments, bills, payment posting, auctions and tax-collector account questions. Use the Treasurer line only when the issue is treasury-related rather than a tax bill.
| Item | Official planning detail | What to verify before action |

| Treasurer-Tax Collector | Karen D. Adams, CPA | Use the official county page for current officeholder and contact information. |
| Physical address | 2222 M St., 1st Floor, Merced, CA 95340 | Check county holiday closure and office status before visiting. |
| Tax Collector phone | (209) 385-7592 | Use for tax payments, bills, auctions and account questions. |
| Treasurer phone | (209) 385-7307 | Use for treasury matters, not ordinary property-tax bill questions. |
| Fax | (209) 725-3905 | Call first before faxing sensitive or deadline-related documents. |

How Merced County Property Taxes Can Be Paid
Merced County lists four main routes: online, phone, mail and in person. Choose based on deadline risk, fee tolerance, confirmation needs and whether your bill is current, delinquent, supplemental, unsecured or defaulted.
Pay online
Use the official View or Pay Taxes Online page. Payments can be made until midnight on the stated due date when the online route is available.
Pay by phone
Use the official pay-by-phone number, (866) 890-4105. Phone payments can include credit card or e-check, with fees where applicable.
Pay by mail
Mail the check and payment stub to Merced County Treasurer-Tax Collector, P.O. Box 6008, Whittier, CA 90607-6008, unless your bill says otherwise.
Pay in person
Pay at 2222 M St. in Merced by 5:00 PM on or before the stated due date. Confirm acceptable payment methods before visiting with a large or late balance.
Online and Phone Payment Fees
Convenience fees are separate from the property tax amount. Merced County says convenience fees are payable to the credit card vendor, not to the County of Merced.
| Payment method | Official fee example | Planning note | Best use |
|---|---|---|---|
| E-check | No convenience fee | Still enter bank information carefully. A confirmation number alone does not guarantee the payment will process if account details or funds are wrong. | Best low-fee online route when eligible. |
| Credit card | 2.34% of taxes paid, $2.00 minimum | Compare the fee with deadline urgency, penalties and any cash-flow benefit. | Useful when speed matters and fee is acceptable. |
| Debit card | $3.95 flat fee | Flat fee may be useful for some payments, but final checkout controls the actual fee display. | Useful for smaller payments when the flat fee is acceptable. |
| Phone payment | Same payment-method fee concept applies | Use the official (866) 890-4105 number and save confirmation. | Useful when online access is difficult but deadline timing matters. |
How to Pay Merced County Property Tax Online
The safest online payment flow is not “click the first result.” Use the county’s official Tax Collector route, identify the correct bill, review fees, and save confirmation until the account updates.
Start from the official county page
Open Merced County’s View or Pay Taxes Online page or the official Tax Collector page, then follow the official payment portal link.
Search carefully
Use your parcel, assessment, account, bill or property information from the official tax bill. If address search fails, try the county’s property-search tips before assuming there is no bill.
Match the correct bill
Confirm tax year, secured/unsecured/supplemental status, installment number, property description and owner/account details before adding a bill to payment.
Review fees and deadline
Check whether you are paying by e-check, card or debit card, and compare the payment time with the stated delinquency date.
Save proof
Save confirmation number, amount, payment method, parcel/account identifier and date. Later, verify whether the payment posted correctly.
Merced County Property Tax Deadlines
California secured property taxes usually use two installments. Merced County’s 2025–2026 notice states the first installment was due November 1 and delinquent if not received or postmarked by December 10, while the second installment was due February 1 and delinquent if not received or postmarked by April 10. Use your current bill and official county page for the active tax year.
| Tax event | Typical Merced County / California timing | What it means | Planning warning |
|---|---|---|---|
| Secured tax bills mailed | Usually October | Annual secured property tax bills are mailed to addresses shown on the tax roll. | Failure to receive a bill does not remove the responsibility to pay on time. |
| First secured installment due | November 1 | The first installment becomes due. | You may pay both installments when the first installment is due. |
| First secured installment delinquent | After December 10 if not paid or postmarked on time | A 10% penalty generally applies, and reminder fees may apply if a reminder notice is generated. | Mail early or get a valid USPS postmark by the delinquent date. |
| Second secured installment due | February 1 | The second installment becomes due. | Do not wait until April 10 if you need help searching or verifying the bill. |
| Second secured installment delinquent | After April 10 if not paid or postmarked on time | A 10% penalty plus a cost can apply. Merced County’s 2026 reminder listed a $55 cost for late second installment payments. | Online and phone payments may be safer than last-minute mail. |
| Unsecured taxes | 2026 unsecured taxes were due August 31, 2026 | Unsecured taxes generally apply to movable or non-real property such as business personal property, boats and airplanes. | If you sold or disposed of the property after January 1, 2026, the county reminder still says the owner must pay the unsecured bill. |
| Tax default date | 12:01 AM on July 1 for unpaid current secured or supplemental taxes | Unpaid secured or supplemental taxes can be declared tax-defaulted. | Redemption penalties, fees and later power-to-sell risk can follow. |
2026 Unsecured Taxes: Business Personal Property, Boats and Airplanes
Merced County’s 2026 unsecured tax reminders are important because unsecured taxes can surprise people who are used to only thinking about real estate bills. An unsecured tax generally refers to property that can be relocated and is not real property.
2026 bills mailed
County reminder materials say 2026 current unsecured tax bills were mailed July 29, 2026, to addresses shown on the unsecured tax roll.
August 31 deadline
The 2026 unsecured taxes were due by Monday, August 31, 2026. If you are checking after that date, ask for the current balance before paying.
Sold after January 1
Merced County’s reminder says if the property was sold or disposed of after January 1, 2026, the property owner still must pay the unsecured tax bill.
Search, Print or Verify a Merced County Tax Bill
Merced County publishes a property-search guide for users trying to view or print tax bills, pay taxes online or verify taxes paid. Address formatting can cause failed searches, so use the county’s search tips before assuming no record exists.
Use bill identifiers first
Parcel, assessment, account or bill numbers are safer than a broad address search when you have the official tax bill.
Shorten address searches
The county suggests trying address searches without words like Street, Road, Drive or Lane if the first search fails.
Try directional abbreviations
For directional names, try N, E, S or W instead of spelling out North, East, South or West.
e-Tax Bills and Property Tax Reminders
Merced County now promotes paperless e-Tax Bills for annual secured and unsecured property taxes. The service can send an email with a bill link, reminders about upcoming due dates and access to download a copy of the bill.
Go paperless
Useful if you want electronic bill access instead of relying only on mailed paper notices.
Due-date reminders
Reminder tools can reduce missed-deadline risk, but they do not replace your responsibility to pay on time.
Keep access current
Make sure the email address stays valid. If you change email accounts, update the official e-billing service.
Supplemental Assessments and Supplemental Tax Bills
Supplemental bills often confuse new owners because they are in addition to the regular annual tax bill. Merced County explains that if the Assessor reappraises your property because of a change in ownership or completed new construction, you may receive a supplemental tax bill.
New construction
Completed new construction can trigger a reassessment and a supplemental tax bill.
Change in ownership
A property purchase or ownership change can lead to a supplemental assessment and separate bill.
Assessor questions
For supplemental assessment value questions, Merced County points users to the Assessor’s Office at (209) 385-7631.
Mobile Home Tax and Tax Clearance Help
Mobile homes in California can be taxed through the local property tax system or handled through vehicle-license style rules depending on history and status. Merced County explains that title transfers for used mobile homes subject to local property taxes may require a tax clearance from the county tax collector.
Permanent foundation
If a mobile home is attached to a permanent foundation, it is generally treated more like conventional real property for tax purposes.
Not on permanent foundation
Mobile homes not on permanent foundations can involve different title and tax clearance steps.
Tax clearance
For a title transfer involving a local-property-tax mobile home, unpaid taxes or fees generally must be resolved before a tax clearance certificate can be issued.
Defaulted Taxes, Redemptions and Installment Plans
If current secured or supplemental taxes remain unpaid as of 12:01 AM on July 1, Merced County says they will be declared tax-defaulted. Once taxes are defaulted, a redemption penalty and fee can attach, and long-term nonpayment can lead to power-to-sell risk.
| Issue | Official rule / planning detail | What to do |
|---|---|---|
| Tax-defaulted status | Current secured or supplemental tax unpaid as of 12:01 AM on July 1 can be declared tax-defaulted. | Call the Tax Collector for the current redemption amount before sending payment. |
| Redemption penalty | Merced County lists a 1½% monthly redemption penalty after default. | Do not calculate the balance yourself from an old notice. |
| Redemption fee | A $15 redemption fee is listed at the time of redemption. | Ask for the full current payoff amount. |
| Payment plan setup | County guidance says payment-plan setup requires 20% or more of the total redemption amount plus other conditions. | Confirm eligibility and due dates before relying on a plan. |
| Annual plan payments | Interim payments of 20% or more of the original redemption amount plus interest are due by April 10 in succeeding fiscal years. | Missing plan conditions can default the plan. |
| Power to sell | If plan conditions fail and the property becomes subject to sale, installment-plan options may be limited. | Act before the fifth year or power-to-sell stage whenever possible. |
Assessor vs Auditor vs Tax Collector: Which Office Do You Need?
Many property-tax problems get delayed because the wrong office is contacted. In California counties, the Treasurer-Tax Collector generally collects and posts payments, while the Assessor handles property value and the Auditor/Controller handles tax rates and calculations.
| Your question | Best office to start with | Why |
|---|---|---|
| How much do I owe? | Tax Collector | The Tax Collector handles tax bills, payments, receipts, delinquency and payment posting. |
| Did my payment post? | Tax Collector | Payment confirmation and tax-account posting are Tax Collector issues. |
| Where do I pay or mail taxes? | Tax Collector | The Tax Collector controls official payment instructions. |
| Why is my assessed value wrong? | Assessor | The Assessor handles values, ownership, property characteristics and assessment roll information. |
| What is my supplemental assessment? | Assessor first, Tax Collector for payment | The Assessor explains the reassessment; the Tax Collector handles the resulting bill payment. |
| Why is the tax rate or special assessment applied? | Auditor/Controller or listed agency | Rates and special assessments may be calculated or placed by agencies outside the Tax Collector. |
| Tax auction or defaulted property question | Tax Collector | The Tax Collector is responsible for auction of tax-defaulted properties. |
What to Have Ready Before You Call, Search or Pay
A Merced County property-tax task is much easier when you already have the right identifiers. Do not rely only on an owner name or partial street address if your official bill shows parcel, assessment or bill details.
- Tax bill: keep the official bill or notice open while searching or paying.
- Parcel or assessment number: use the identifier shown on the county bill or tax record.
- Tax year: confirm whether you are paying 2025–2026, 2026–2027, a prior year, or a supplemental/unsecured bill.
- Installment: confirm first installment, second installment, both installments, delinquent amount, or redemption payoff.
- Property type: check whether the bill is secured, unsecured, supplemental, mobile home, business personal property, boat or aircraft related.
- Payment method: review e-check, card, debit, phone, mail or in-person rules before sending money.
- Mailing proof: if mailing close to a deadline, make sure you understand USPS postmark requirements.
- Confirmation proof: save receipts and verify payment posting later.
Mail and Postmark Warning
Merced County says mailed payments must be postmarked on or before the stated due date to avoid penalty. When a deadline is close, simply dropping an envelope in a mailbox may not give you the proof you need.
Use USPS carefully
Payments sent by mail should receive a valid USPS postmark by the delinquent date. Ask for a counter postmark if timing matters.
Include the stub
Mail the payment stub with your check so the payment is applied to the correct bill and installment.
Keep records
Keep copies of the bill, check, money order, tracking, receipt and postmark proof until payment posting is confirmed.
