If you live or run a business in Oroville, the tax bill comes from several directions: a combined sales and use tax of 9.25% at the register, annual property taxes billed by Butte County, a 9% transient occupancy tax on short-term lodging, a utility user tax on your monthly service bills, and a city business license fee for anyone operating within city limits. Each Oroville tax has its own rate, deadline, and payment channel, and missing any of them triggers penalties that stack quickly.
Sales and Use Tax
The combined sales and use tax rate in Oroville is 9.25%, applied to most retail purchases of tangible goods within city limits.1California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates That rate stacks the statewide base with county and city add-ons. One of those local layers is the 1% transactions and use tax authorized by voter-approved Measure U, codified in Oroville Municipal Code Chapter 3.18.2City of Oroville, CA. City of Oroville Code – Chapter 3.18 Transactions and Use Tax Measure U revenue flows into the city’s general fund and supports day-to-day municipal operations rather than being earmarked for a single project.3Butte County Clerk-Recorder. Measure U City of Oroville – Transactions and Use Tax
Retailers collect the tax and remit it to the California Department of Tax and Fee Administration, which distributes the local share back to Oroville. Most food products sold for home consumption and prescription medicines are exempt.4California Department of Tax and Fee Administration. Tax Guide for Grocery Stores Hot prepared food, carbonated beverages, and food sold for on-premises consumption are generally taxable.
Property Tax
Property taxes in Oroville follow California’s Proposition 13 framework. The base rate is capped at 1% of assessed value, plus any additional levies voters approved for bonds or special districts. Assessed value starts at what you paid for the property and can rise by no more than 2% per year unless the property changes hands or undergoes new construction.5California State Board of Equalization. California Property Tax An Overview Over years of ownership the gap between assessed value and market value can grow, which is why longtime homeowners often pay far less than recent buyers on comparable homes.
Due Dates and Penalties
The Butte County Treasurer-Tax Collector handles all billing and collection for Oroville property owners and distributes the revenue among the county, cities, school districts, and special districts.6Butte County, CA. Property Taxes The annual bill splits into two installments:
- First installment: due November 1, delinquent after 5 p.m. on December 10.
- Second installment: due February 1, delinquent after 5 p.m. on April 10.7Butte County, CA. New Property Owner Information
Miss either deadline and you owe a 10% penalty on the delinquent installment. It applies automatically the day after the delinquency date, with no grace period. Properties that remain unpaid eventually become tax-defaulted, which adds interest and can lead to a tax sale.
Challenging Your Assessment
If you believe your property is overvalued, you can file a formal appeal with the Butte County Assessment Appeals Board through the Clerk of the Board of Supervisors in Oroville. The regular filing period runs from July 2 through November 30 each year. For supplemental assessments triggered by a purchase or new construction, you have 60 days from the date of the supplemental assessment notice.8Butte County, CA. Assessment Appeals
The most common grounds are that the assessor’s estimated market value exceeds what the property would actually sell for, or that similar nearby properties carry lower assessments. Bring documentation: a recent appraisal, comparable sales data, or evidence that the assessor relied on incorrect property details like an overstated square footage.
Transient Occupancy Tax
Anyone renting out a hotel room, vacation rental, or other short-term accommodation in Oroville collects a 9% transient occupancy tax on the rent charged to guests. Under Chapter 3.20 of the Municipal Code, anyone staying 60 consecutive days or less counts as a transient and owes the tax. If a stay extends past 60 days, only the first 60 days are taxable.9City of Oroville, CA. City of Oroville Code – Chapter 3.20 Uniform Transient Occupancy Tax
Lodging operators add the tax to the guest’s bill and remit it to the city. Late remittance penalties escalate:
- Initial delinquency: 10% of the tax owed.
- Still delinquent after 30 days: an additional 10% penalty on top of the first.
- Fraud: a 100% penalty on top of the unpaid tax.
- Interest: 1% per month on the unpaid tax, running from the original delinquency date until paid.9City of Oroville, CA. City of Oroville Code – Chapter 3.20 Uniform Transient Occupancy Tax
If you list a property on Airbnb or Vrbo, check whether the platform automatically collects and remits the transient occupancy tax to Oroville. Where it doesn’t, the operator is personally responsible for collecting from guests and paying the city. Delinquencies persisting more than 60 days begin accruing interest on the penalties themselves.
Utility User Tax
Oroville imposes a utility user tax on several household and business services. Electricity, gas, and water are taxed at 5%. Telecommunications and video services, including cable and internet-based TV, are taxed at 4.5%. Your utility provider adds this tax to your monthly bill and remits it to the city, so most residents see it as a line item rather than a separate filing obligation. Revenue goes into the city’s general fund alongside Measure U proceeds.
Business License Tax
Every person or entity conducting business within Oroville must obtain a business license from the city. Under Municipal Code Chapter 5.04, you apply by submitting a written application to the city’s finance officer with the information needed to determine the correct license fee.10City of Oroville, CA. City of Oroville Code – Chapter 5.04 Business Licenses Generally – Section 5.04.030 Applications If the fee is calculated based on average employee count, you report that figure for the applicable period. The city directs applicants to obtain the combined occupancy and business license packet from the Building Department.11Oroville, CA. Business License
Accuracy on the application matters, since the information you provide directly determines the fee. Incorrect figures can trigger a corrected assessment or require an amended filing. Businesses with employees also need a federal Employer Identification Number from the IRS before they can properly handle payroll and remit employment taxes.12Internal Revenue Service.

Federal Deduction for Oroville Taxes
Oroville residents who itemize on their federal return can deduct state and local taxes, subject to a cap. For tax year 2026 the limit is $40,400 for most filers and $20,200 for married individuals filing separately. That cap covers the combined total of your California income tax, Oroville property taxes, and any other deductible state or local levies. For higher earners, the deduction phases down: if your modified adjusted gross income exceeds $505,000 ($252,500 for separate filers), the cap is reduced by 30% of the excess, though it never drops below $10,000.13Office of the Law Revision Counsel. 26 USC 164 – Taxes
For property owners who rent out lodging, rental income is generally reported on Schedule E. One exception: if you rent your home for fewer than 15 days during the year, you don’t report the rental income and can’t deduct rental expenses.14Internal Revenue Service. Topic No. 415, Renting Residential and Vacation Property Once you cross the 14-day threshold, all rental income becomes reportable, and you can offset it with deductible expenses like repairs, insurance, and the transient occupancy tax you collected and remitted.
How and Where to Pay
Property tax payments go through the Butte County Treasurer-Tax Collector, not the City of Oroville. You can pay online with a credit card or e-check through the county’s payment system. Credit card payments carry a 2.30% service fee and debit cards cost $3.49 per transaction. Mailed payments by check or money order should be made payable to the Butte County Tax Collector, and the postmark must be on or before the due date. Cash, checks, and money orders are also accepted in person at the Tax Collector’s front counter.15Butte County. Property Taxes
City-collected taxes, including the business license fee and transient occupancy tax, are handled separately through the City of Oroville Finance Department. Keep confirmation receipts and your business license certificate after payment. Those documents serve as proof of compliance if you face a city audit or need to renew your license.
