How Property Tax Works

Glenn County's property tax system operates under California's Proposition 13 framework, providing essential funding for local government services, schools, fire protection, and special districts throughout the county. Property taxes in Glenn County are collected by the County Tax Collector and distributed to various local agencies based on assessed values and voter-approved tax rates. The county follows California's standard assessment practices, with properties reassessed upon ownership changes or new construction, and annual assessment increases capped at 2% for existing ownership.

Effective property tax rates in Glenn County vary by location within the county due to different combinations of special taxing districts, school bonds, and community facilities districts (CFDs). While the base county-wide rate provides a foundation, property owners may pay additional assessments depending on their specific location and the services provided by local districts. As of 2025, Glenn County implemented Measure A, significantly impacting the overall tax structure, with rates now varying considerably based on the specific taxing districts that serve each property.

Supplemental Tax Bills

Supplemental taxes in Glenn County are triggered by two main events: change of ownership or completion of new construction. When either occurs, the County Assessor determines the new assessed value and calculates a supplemental assessment covering the period from the event date through the end of the current fiscal year (June 30). This supplemental tax is prorated based on the number of months remaining in the fiscal year.

For example, if a property sells on October 1st and the assessed value increases from $400,000 to $600,000, the supplemental tax would apply to the $200,000 increase for the remaining 9 months of the fiscal year. Using a 1.2% effective tax rate, the calculation would be: ($200,000 × 0.012 × 9/12 = $1,800). The supplemental tax bill is typically mailed within 90 days of the triggering event and becomes due immediately upon issuance. This is separate from and in addition to the regular annual property tax bill.

Escrow & Property Taxes

Most mortgage lenders in Glenn County require property tax escrow accounts, collecting monthly payments equal to 1/12 of the annual tax bill plus insurance premiums. Lenders typically collect an additional 2-3 months of taxes at closing to establish the escrow account and ensure sufficient funds for payment. The lender pays property taxes directly to Glenn County on behalf of the borrower when bills become due.

Property owners should verify that their lender pays taxes correctly and on time, as the property owner remains ultimately responsible for tax payments even when using escrow. Glenn County sends tax bills to the property address, but lenders may not automatically receive copies unless specifically requested. Escrow accounts are analyzed annually, and lenders will adjust monthly payments based on changes in tax assessments or tax rates. Property owners can request escrow account statements and should review annual escrow analyses to ensure accuracy.

Frequently Asked Questions

Q: When are property taxes due in Glenn County for FY 2025-2026? A: Property taxes are due in two installments - the first installment is due April 15, 2026, and the second installment is due November 15, 2026, based on Glenn County's local payment schedule.

Q: What tax credits are available and do they require application? A: The primary tax credit is the Homeowners' Exemption, providing $7,000 reduction in assessed value (saving approximately $70-135 annually). This REQUIRES annual application and is not automatic. Veterans' exemptions and senior/disabled person property tax postponement programs are also available but require separate applications with specific deadlines.

Q: How does the Homestead exemption work in California? A: California does not have a traditional "homestead exemption." The Homeowners' Exemption reduces assessed value by $7,000 for owner-occupied residences. Additionally, Proposition 13 caps annual assessment increases at 2% for existing owners, but this is automatic and does not require filing.

Q: When does Glenn County reassess properties? A: Properties are reassessed upon change of ownership or completion of new construction. Otherwise, assessed values can only increase by a maximum of 2% annually under Proposition 13. Mass appraisal updates occur annually as of January 1st.

Q: What is the appeals process and deadline? A: Assessment appeals must be filed during the regular filing period, typically July 2 through September 16 or December 2 (depending on when assessment notices are mailed). Appeals are heard by the Glenn County Assessment Appeals Board.

Q: What are the late payment penalties? A: Late payments incur a 10% penalty if paid after the due date, plus 1.5% interest per month. Additional costs may include collection fees and potential tax lien procedures for extended delinquencies.

Q: Can I pay property taxes online? A: Yes, Glenn County offers online payment options through the County Tax Collector's website. Electronic payments, credit card payments, and traditional mail payments are typically accepted.

Q: Why do some properties in Glenn County have higher tax rates? A: Tax rates vary based on special taxing districts serving each property, including school districts, fire districts, and Mello-Roos Community Facilities Districts (CFDs). Properties in newer developments or areas with voter-approved bond measures often have higher effective rates due to these additional assessments.
