Where to Start the Search
The Marin County Assessor-Recorder-County Clerk (ARCC) hosts the public lookup system on its main site. Property owners can launch the portal at https://arcc.marincounty.gov/ and select the property search option from the main menu. The search returns current assessment data, parcel maps, and a link to the most recent tax bill through the Treasurer-Tax Collector system.

Marin County Property Tax Rates
California sets a base property tax rate of 1% of assessed value under Proposition 13. Local voters in Marin County have approved parcel taxes, school bonds, and special assessments that raise the effective rate above the 1% floor. The combined rate varies by location because each community falls into a different set of school and community college districts.
How the Rate Is Built
The 1% general tax funds county services, fire protection, and basic municipal operations. Voter-approved debt for schools, community colleges, and special districts is added on top of the 1% rate. Flood control, mosquito abatement, and recreation districts apply their own rates that show as separate line items on each tax bill.
Where to Find the Rate Book
The Auditor-Controller publishes an annual Property Tax Rate Book for each fiscal year. The rate book lists the 1% base rate, every voter-approved override, and the special assessment applied to each Tax Rate Area. For alternative formats, contact the Auditor-Controller’s office by phone at 415-473-6154 or through the County website. California relay users may dial 711.
Property Tax Payment Methods
The Marin County Tax Collector offers four standard payment channels: online, phone, drop box, and mail. The Tax Collector’s office also accepts in-person payments during regular business hours. Each method has its own processing timeline, and the postmark on mailed payments determines the official date of receipt under California law.

Office hours are Monday through Friday 9 a.m. to 4:30 p.m., closed holidays. A secure drop box sits outside the office and is available during extended hours around the installment deadline. Payments placed in the drop box after 5 p.m. are dated the next business day.
Property Tax Deadlines and Calendar
Marin County mails secured property tax bills once a year in early October. The annual bill covers two installments. The first installment becomes delinquent at 5 p.m. on December 10. The second installment of the 2026-26 property tax bill is due by April 10. Refer to the County’s official Property Tax Calendar for the most current installment dates.
Annual Installment Schedule

|---|---|
| First installment | 5 p.m. on December 10 |
| Second installment | 5 p.m. on April 10 |
Mailed Payment Rules
Payments sent through the U.S. Postal Service must be postmarked on or before the delinquency date to count as on time. The Postal Service changed its postmark policy in recent years, and only certain mail classes receive a same-day postmark. Taxpayers who mail payments close to the deadline should use certified mail with a return receipt to prove the postmark date.
Property Tax Exemptions Available in Marin County
California property tax law offers several exemptions that reduce the assessed value or total bill for qualifying owners. Marin County administers the Homeowners’ Exemption directly, while school and special districts run their own parcel tax exemption programs. The County Assessor’s Exemptions Division reviews each claim and verifies eligibility before applying the reduction.
Common Exemption Types
| Exemption | Maximum Reduction | Eligibility | Filing Form |
|---|---|---|---|
| Homeowners’ Exemption | Up to $7,000 of assessed value | Owner-occupied principal residence | BOE-266 |
| Senior Citizen Parcel Tax Exemption | Varies by district | Over age 65, principal residence | District-specific form |
| Contiguous Parcel Exemption | Varies | Adjacent parcels used together | District-specific form |
How to File the Homeowners’ Exemption
First-time claimants file Form BOE-266 with the Marin County Assessor. The form asks for the property address, owner information, and a declaration that the home is the owner’s principal residence. Claims filed within 30 days of a supplemental notice apply to the new assessment. The County reviews the claim and updates the parcel record when approved. For additional information, contact the Marin County Assessor Exemptions Division at 415-473-3794.
Parcel Tax Exemption Application
Most school and special districts grant a parcel tax exemption to seniors who own and occupy the property as their principal residence. Each district sets its own age threshold, income test, and renewal cycle. Application forms for Senior Exemptions and Contiguous Parcel Exemptions for the current fiscal year are available, and the Marin County Free Library maintains a public list of parcel tax exemption forms. The application deadline for the current cycle is June 1, 2026.
How to Appeal a Property Tax Assessment
Property owners who disagree with the Assessor’s enrolled value may file an Assessment Appeal Application with the Marin County Clerk of the Assessment Appeals Board. The application period for the 2026-27 regular property tax bill opens on July 2, 2026 and closes on November 30, 2026. Late applications are not accepted, and missing the deadline forfeits the right to challenge the value for that tax year.
Filing the Appeal
Applicants download the Assessment Appeal Application from the County website or pick up a copy in person. The form asks for the parcel number, the disputed value, and the owner’s opinion of market value. Supporting evidence such as a recent appraisal, comparable sales, or photographs of property damage is attached to the application. Applicants should be prepared to submit additional information if requested by the Assessor or at the time of the hearing.
What Happens After Filing
The Assessment Appeals Board schedules a hearing after a complete filing is received. The Assessor’s office receives a copy of the application and may offer a stipulated value before the hearing. If both parties reach a settlement, the appeal closes without a hearing. Hearings that proceed to a full review include sworn testimony and a written decision from the Board.
Supplemental and Escape Assessments
Owners who receive a Supplemental Assessment Notice should review the appeal instructions included with the notice. Escape assessments, which add newly discovered taxable value, follow a different appeal path and require direct contact with the Assessor before a formal hearing is scheduled.
Property Tax Deferral and Assistance Programs
California’s Property Tax Assistance program allows blind, disabled, and senior citizen homeowners to defer payment of current-year property taxes. A lien is recorded against the property, and the County settles the debt from the estate or from the property’s eventual sale. Interest accrues on the deferred amount at a rate set annually by the State. Refer to the Tax Collector’s Property Tax Assistance page for the current eligibility requirements.
Deferral Eligibility at a Glance
- Senior citizen, OR blind, OR disabled (as defined by the State)
- Owner-occupant of the property as the principal residence
- Annual household income at or below the program ceiling
- Sufficient equity in the property
- No reverse mortgage or other deferred-payment lien in first position
How to Apply
Applicants request a deferral claim form from the Tax Collector’s office. The claim package includes an application, an income affidavit, and instructions for recording the lien. Approved applicants defer the current-year bill and receive a confirmation letter that releases the County from collection activity for the deferred year.
Special Assessment Districts and Parcel Taxes
Marin County contains dozens of special districts that levy parcel taxes for specific services. Fire protection districts, water districts, sanitary districts, recreation districts, and school districts each run their own ballot measures. The total bill for any single parcel can include charges from ten or more taxing agencies, depending on location.
Common Special Charges on a Marin Bill
- School district parcel taxes and bond repayments
- Community college district parcel taxes and bond repayments
- Municipal fire protection and paramedic services
- Recreation and park maintenance districts
- Flood control and storm water districts
- Mosquito and vector control assessments
- Library and museum parcel taxes
Where to Verify District Charges
The Auditor-Controller’s rate schedule lists every direct charge applied to a Tax Rate Area. Property owners match the parcel number to a Tax Rate Area to see the full list of district charges. The current fiscal year rate schedule is posted on the Auditor-Controller’s page in PDF format.
Commercial Property Tax in Marin County
Commercial and industrial property owners receive a separate bill component for business personal property in addition to the real property levy. Fixtures, equipment, machinery, and leasehold improvements may be assessed as business personal property when they are not part of the real estate transaction. The Assessor’s Business Property Division manages these accounts and answers questions about filing requirements.
Business Personal Property Filing
Business owners file a Business Property Statement each year when the Assessor requests it. The statement reports acquisition cost, depreciation, and a description of each asset class. Failure to file a requested statement can result in penalties on the assessed value, and continued non-filing may lead to an estimated assessment based on industry averages.
Unsecured Tax Bills
Business personal property, boats, and airplanes are billed on the unsecured roll. Unsecured bills are mailed separately from secured property tax bills and have different delinquency dates. The Tax Collector’s Unsecured Tax page provides the unsecured payment schedule and contact details for resolution questions.
Vacant Land Property Tax
Vacant parcels are assessed at market value in the same way as improved property. The 1% base rate still applies, and the parcel may carry special assessments for fire protection, weed abatement, and storm water runoff. Owners of buildable vacant land often face higher effective rates than owners of similar improved parcels because no exemption applies to bare land.
Key Considerations for Vacant Land
- No Homeowners’ Exemption can be claimed
- Fire suppression and weed abatement assessments apply
- Penalties for non-payment mirror improved property rules
- Subdivision or improvement triggers a supplemental reassessment
Mortgage Escrow and Property Tax
Most Marin homeowners pay property taxes through a mortgage escrow account. The lender collects a portion of the annual tax bill with each monthly mortgage payment and remits the payment to the County on the owner’s behalf. Escrow accounts cushion the homeowner from large lump-sum payments and reduce the risk of delinquency.
How an Escrow Account Works
The lender estimates the annual property tax bill at closing and divides it by 12 to set the monthly escrow contribution. The servicer reviews the escrow balance each year and recalculates the monthly payment based on the actual tax bill received from the County. A shortage or surplus at the annual analysis triggers an adjustment to the monthly mortgage payment.
When the Lender Pays Late
Taxpayers who pay through escrow should verify that the lender remits the payment before the delinquency date. County records confirm the date the payment was received. If a lender fails to pay on time and a penalty accrues, the borrower may request a refund under the County’s penalty cancellation process.
Property Tax Delinquencies and Penalty Resolution
Unpaid property taxes become delinquent after the installment due date. Penalties attach after the delinquency date, and additional costs accrue at set dates under California law. After five years of delinquency, the Treasurer-Tax Collector may start the tax-defaulted land sale process, which can transfer ownership of the parcel to a third party at public auction.
Resolving a Delinquent Bill
Owners who fall behind on property taxes should contact the Tax Collector’s office as soon as possible. The office offers installment payment plans for owners who can demonstrate the ability to cure the default over time. Accepted plans stop additional penalties from accruing while the owner remits monthly payments under the agreement.
Penalty Cancellation Requests
A penalty may be cancelled when the late payment resulted from a County error, a disaster declared by the Governor, or a serious medical or financial hardship. The taxpayer files a Penalty Cancellation Request with documentation that supports the reason for late payment. Each request receives an independent review by Tax Collector staff.
Using a Property Tax Calculator
A property tax calculator multiplies the assessed value by the total applicable rate to estimate the annual bill. Marin County property owners can build a custom estimate by combining the 1% base rate with all voter-approved and special district charges that apply to their Tax Rate Area. The Assessor’s portal provides the current assessed value, and the rate schedule provides the total rate.
Calculator Formula
- Find the assessed value from the Assessor’s parcel search.
- Identify the Tax Rate Area from the same parcel record.
- Match the Tax Rate Area to the total rate in the current rate book.
- Multiply the assessed value by the total rate to get the annual bill.
- Divide the annual bill by two for the standard installment amount.
Annual Assessment Cap
Proposition 13 limits the annual increase in assessed value to the lesser of 2% or the local rate of inflation. The cap applies each year the property changes ownership or completes new construction. A change in ownership resets the assessed value to the new market value at the time of sale, which can raise the bill sharply in a rising market.
Tax Roll Search and Public Records
The Recorder’s office indexes every recorded document that affects a Marin parcel, including deeds, deeds of trust, liens, and homestead declarations. The Recorders Index Search portal allows property owners to retrieve recorded documents by name, document type, recording date, or instrument number. A copy fee applies to certified and non-certified copies of each document.
Where to Run a Records Search
The public search portal is available through the ARCC main site. Searches return the recording date, document number, and a list of parties named on the document. Customers can purchase official copies online and download them immediately for printing.
Document Types Available
- Grant deeds and quitclaim deeds
- Deeds of trust and reconveyances
- Liens, judgments, and releases
- Homestead declarations
- Trust transfers and probate documents
- Miscellaneous official records
California Property Tax Law Context for Marin Owners
California property tax law rests on Proposition 13, passed by voters in 1978. The proposition set the 1% base rate, established the 2% annual cap on assessed value, and created the change-in-ownership reassessment rule. Subsequent ballot measures and court decisions have added exemptions, transferred tax functions between agencies, and created new relief programs that apply to Marin County parcels.
Key Rules That Apply to Marin Parcels
- Base property tax rate of 1% of assessed value
- Annual assessed value increase capped at 2% or inflation, whichever is lower
- Reassessment to current market value on change of ownership or new construction
- Homeowners’ Exemption of up to $7,000 of assessed value for owner-occupants
- Parent-child and grandparent-grandchild transfer exclusion under defined conditions
Recent Law Changes
The California State Legislature has updated exemption amounts and clarified filing deadlines in recent sessions. Property owners who claim a parent-child or grandparent-grandchild transfer should review the current law before completing a deed to confirm eligibility. The State Board of Equalization publishes updated claim forms and instructions when statutes change.
