Rate Breakdown

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

How Property Tax Works in Colusa County

In Colima County, property taxes are calculated on the assessed value of real‑estate as determined by the County Assessor‑Recorder’s Office. The assessment is generally set at 1 % of the property's market value under California’s Proposition 13, with the assessed value remaining frozen until a change of ownership or new construction triggers a reassessment. From this base, the County adds a series of levies—known as millage rates—expressed in milles (one thousandth of a dollar) to fund schools, public safety, roads, and other local services.

For the 2024‑25 fiscal year, the combined general tax rate for Colusa County is approximately 1.25 % (12.5 mills). Specific districts (e.g., elementary school districts, community college, fire protection) may add additional mills, so the total rate a homeowner pays often ranges between 1.30 % and 1.50 % of the assessed value. The Assessor’s website provides a detailed millage table so you can see exactly which agencies receive a portion of your payment.

Available Exemptions

California law offers several exemptions that can reduce the taxable portion of your property’s assessed value. While the state sets the baseline, many exemptions are administered locally, and Colusa County follows the same guidelines.

• Homestead Exemption (Proposition 13) – Automatically limits the annual increase in assessed value to a maximum of 2 % regardless of market appreciation.
• Senior Citizen or Disabled Owner Exemption – Provides a $7,000 reduction in assessed value for homeowners who are 65 years or older, or who are classified as disabled, subject to income limits set by the state.
• Veteran’s Exemption – Grants a $5,000 reduction for qualified disabled veterans. An additional $5,000 may be available for veterans who are totally and permanently disabled.
• Parent–Child and Grandparent–Grandchild Transfer Exemptions – Allows eligible transfers of property between family members without triggering a reassessment, preserving the original low base value.

To claim any exemption, submit the appropriate claim forms to the Colusa County Assessor’s Office by the filing deadline (typically March 1 of the tax year). Required documentation may include proof of age, disability status, veteran status, and income.

Payment Schedule & Deadlines

Colusa County property taxes are paid in two installments. Missing a deadline can result in penalties, interest, and possible tax‑sale actions.

• First Installment – Due November 1, with a grace period ending December 10. Payments made after December 10 incur a 10 % penalty plus 0.5 % monthly interest.
• Second Installment – Due February 1, with a grace period ending April 10. Late payments attract the same 10 % penalty and interest.
• Late‑Payment Penalties – After the grace period, a 10 % penalty is applied to the overdue amount, followed by compounded interest calculated daily at the statutory rate.
• Payment Options – Pay online via the County Treasurer‑Tax Collector’s portal, by mail with a check or money order, or in person at any Treasurer‑Tax Collector office. Some banks also accept electronic funds transfers.

Homeowners who qualify for the “senior or disabled exemption” may apply for a payment plan that spreads the total tax bill over four quarterly installments, but the first payment must still be made by the November deadline.

Appealing Your Assessment

If you believe your property has been over‑assessed, you have the right to file an appeal with the Colusa County Assessment Appeals Board (AAB). The process is straightforward but time‑sensitive.

• Step 1 – Review Your Notice of Assessment – Carefully examine the assessed value and any applied exemptions.
• Step 2 – File a Formal Appeal – Submit a completed “Property Tax Appeal Request” (Form 281) to the AAB within 60 days of the mailing date of your notice. Late filings are generally not accepted.
• Step 3 – Gather Evidence – Compile comparable sales, an independent appraisal, or proof of damage that may affect value.
• Step 4 – Attend the Hearing – The AAB will schedule a hearing, usually within 90 days of your filing. Present your evidence and answer any questions from the board members.
• Step 5 – Receive a Decision – The board issues a written decision within 30 days of the hearing. If you disagree, you may appeal further to the California State Board of Equalization.

Throughout the appeal, maintain copies of all correspondence and records. An experienced property tax consultant or attorney can help you navigate the process and increase the likelihood of a favorable outcome.
