Butte CA Property Tax Due Dates 2026-27
Butte County secured property taxes follow California’s two-installment schedule. Bills are generally mailed in October, with the first installment due November 1 and the second due February 1. The more important dates for avoiding penalties are December 10 and April 10.
First Installment
November 1, 2026 First installment of the 2026–27 secured property tax bill.
First Installment Delinquent
December 10, 2026 A 10% penalty applies after 5:00 p.m. if the first installment remains unpaid.
Second Installment
February 1, 2027 Second installment of the 2026–27 secured property tax bill.
Second Installment Delinquent
April 10, 2027 A 10% penalty plus a $10 cost applies after 5:00 p.m. if unpaid.
Important: December 10, 2026 and April 10, 2027 fall on weekdays, so the normal deadlines apply. The county notes that when a delinquent date falls on a weekend or legal holiday, payment by 5:00 p.m. on the next business day avoids the penalty.
Butte County Property Tax Penalties
Late property-tax payments in Butte County can add penalties and county costs to the bill. Property owners should watch both installment deadlines, especially when mailing payment, using online payments near midnight, or paying after a parcel has already become delinquent.
What Happens If You Miss a Payment?
For the 2026-27 secured roll, the first installment becomes delinquent after December 10, 2026 at 5 p.m., and Butte County adds a 10% penalty. The second installment is tied to April 10, 2027; because that date falls on Saturday, verify the next-business-day deadline. Butte County lists a 10% penalty plus an additional $44 charge after the second-installment deadline.
Important Reminder for Property Owners
Butte County accepts online payments as timely if paid by midnight on the final due date, while mailed payments generally depend on the postmark. Check the official parcel balance, payment method rules, and any delinquent-roll status before assuming a payment will be accepted without penalty.

How to Calculate Your Butte County Property Tax
Start with the property’s assessed value, choose the closest Butte County local area, and add any known exemptions, special assessments, or direct charges. The calculator provides a planning estimate and should not be treated as an official Butte County tax bill.
Step 1
Enter the assessed value, which is the taxable value used before exemptions, bonds, and direct charges are added.
Step 2
Select a local context such as Chico, Oroville, Paradise, Gridley, Biggs, or an unincorporated area.
Step 3
Enter the exact TRA rate if the parcel's official tax-rate area is known from county records.
Step 4
Apply the homeowner exemption only when the property qualifies as an owner-occupied principal residence.
Step 5
Add special assessments or fixed charges that appear as separate line items on the tax bill.
Step 6
Include Mello-Roos or CFD charges if the parcel is located in a community facilities district.
Step 7
Enter parcel taxes or local direct charges tied to schools, services, or special districts.
Step 8
Use a projected assessed-value increase for planning, while remembering California law controls actual increases.
Step 9
Click Calculate Tax to combine taxable value, rate, exemptions, and charges into an estimated result.
Butte County Property Tax Calculation Formula
Property Tax = 1% of Taxable Value + Voter-Approved Bond Debt + Applicable Special Assessments

FAQ's
Why can Butte County properties in Chico and Oroville have different tax bills?
Two properties can have different assessed values, tax-rate areas, voter-approved debt, exemptions, and direct charges. A Chico parcel may not have the same local obligations as a parcel in Oroville, Paradise, or an unincorporated area.
Can I appeal a Butte County property assessment?
Proposition 13 generally limits the base property tax rate and restricts annual increases in assessed value, with reassessment rules applying when certain ownership or property changes occur.
How often is a property reassessed in Alameda County?
Property owners who disagree with an assessed value should contact the Butte County Assessor and confirm formal assessment appeal deadlines, forms, evidence requirements, and filing procedures.
Can buying a home in Butte County create a supplemental tax bill?
Yes. Butte County tells new property owners that a purchase can trigger reassessment and a supplemental tax bill reflecting the difference between the prior value and the new assessed value.
What happens if my Butte County tax bill went to the previous owner?
New owners remain responsible for paying property taxes on time even if the bill was mailed to the prior owner. Butte County recommends requesting a duplicate bill if needed.
Can improvements increase my Butte County assessment?
Completed new construction can trigger reappraisal. Butte County’s Assessor identifies buildings, structures, wells, septic systems, roads, orchards, vineyards, and certain fixtures as taxable improvements.
Are mobile homes treated differently in Butte County?
Butte County notes that manufactured homes purchased after June 30, 1980 are subject to local property taxes, while older units may be licensed or placed on the local roll.
Where can I verify an official Butte County tax balance?
Use Butte County Treasurer-Tax Collector’s online payment system or contact the Property Tax Division. The calculator cannot confirm whether a parcel is paid, delinquent, or corrected.
What should I gather before estimating?
Collect the assessed value, assessment number or parcel number, tax bill, local area, homeowner exemption status, TRA rate if known, special assessments, and direct charges.
Why might my estimate differ from the actual Butte County bill?
The official bill may include parcel-specific bonds, direct assessments, supplemental taxes, prior-year balances, penalties, corrections, or payment-processing details that are not visible from general inputs.
