Rate Breakdown

Property taxes in Glenn County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Glenn County

Glenn County follows California’s statewide property‑tax framework, which is anchored by Proposition 13 (1978). Each taxable parcel is first assessed at its current market value, but the assessed value can only increase by a maximum of 2 % per year, regardless of market fluctuations. The county assessor’s office determines the market value through an annual “base‑year” assessment (the 1975–1976 fiscal year for most properties) and then applies the capped annual growth.

Once the assessed value is established, the tax bill is calculated by applying the local and special‑district millage rates. One mill equals $1 of tax per $1,000 of assessed value. In Glenn County the typical millage includes:

• County General Fund: ~10 mills
• School Districts (K‑12): ~18 mills
• Community College District: ~2 mills
• Fire Protection, Water, and Other Special Districts: 3–6 mills combined

These rates can vary slightly each year depending on voter‑approved bonds or budgetary changes. To estimate your tax, multiply the assessed value by the total millage (expressed as a decimal) and divide by 1,000. For example, a property assessed at $150,000 with a total millage of 30 mills would produce a tax bill of $4,500 ($150,000 × 0.030).

Available Exemptions

California offers several exemptions that can reduce the taxable portion of your real‑property value. They apply in Glenn County as they do statewide, provided you meet the eligibility criteria.

• Homestead Exemption: A $7,000 reduction in assessed value for owner‑occupied residences. This exemption is automatic for qualifying homeowners.
• Senior Citizen Exemption (Proposition 19): Homeowners aged 55 or older (or disabled) can transfer their existing assessed value to a replacement home of equal or lesser value within the county, preserving lower taxes.
• Disability Exemption (Proposition 19): Same transfer benefit applies to qualified disabled persons, allowing them to move without resetting the assessment.
• Veteran Exemption: A $5,000 reduction for qualifying disabled veterans or surviving spouses. The exemption is applied to the assessed value and is not subject to the 2 % cap.

To claim any exemption, submit the appropriate form to the Glenn County Assessor’s Office before the March 1 filing deadline (or by the date specified on the notice you receive). Supporting documentation—such as proof of age, disability, or veteran status—must accompany the application.

Payment Schedule & Deadlines

Glenn County property taxes are due in two installments:

• First Installment: November 1 – December 10 (late after December 10 incurs a 10 % penalty).
• Second Installment: February 1 – April 10 (late after April 10 incurs a 10 % penalty plus interest).

If both installments are paid on time, there is no additional charge. Late payments trigger the statutory penalty and accrue interest at the prevailing rate (currently 0.5 % per month). Persistent delinquency can lead to a tax‑sale notice, where the county may auction the lien to recover the owed amount.

Taxpayers may also opt for automatic electronic payments (e‑Bill Pay) or use the county’s online portal to schedule recurring payments, which helps avoid missed deadlines.

Appealing Your Assessment

If you believe your assessed value is inaccurate, you have the right to contest it through the following steps:

• Step 1 – Review the Assessment Notice: You will receive a notice of assessed value each July. Verify the property description, market data, and any recent improvements.
• Step 2 – File a Formal Protest: Submit a written protest to the Glenn County Board of Equalization by the October 15 deadline (or the date listed on the notice). Include supporting evidence such as recent sales of comparable properties, appraisals, or photographs of the property’s condition.
• Step 3 – Attend the Hearing: The Board will schedule a hearing, typically in November. You may present your case in person or via a qualified representative (e.g., a real‑estate attorney or tax consultant).
• Step 4 – Receive a Decision: The Board issues a written determination, usually within 30 days. If the decision is unfavorable, you may appeal to the Superior Court of California, County of Glenn, within 30 days of the Board’s ruling.

Preparing a clear, data‑driven protest and meeting all filing deadlines maximizes the chance of a successful adjustment to your property tax bill.
