Oxnard anchors the Ventura County coast and the rich farmland of the Oxnard Plain. The Channel Islands Harbor, the nearby Port of Hueneme, the beaches, Heritage Square, and The Collection shopping center round out an economy that blends agriculture, logistics, retail, and a large, diverse residential base. It is the biggest market in the county, and a varied one.
That scale and that diversity are the opportunity. Getting open cleanly, with the right Business Tax Certificate and permits, sets the foundation. Getting found by customers comes next. This guide covers the first in detail, then points you to the second at the end.
//The sequence
How to start a business in Oxnard, step by step.
This is the order that works for most new Oxnard businesses. Requirements vary by entity, location and industry, so use the city, county and state sources below to confirm what applies to yours.
- 1
Register the business and the name
Form an LLC or corporation with the California Secretary of State through bizfile Online, or stay a sole proprietor. If you use a name that is not your legal name, file a fictitious business name (DBA) statement with the Ventura County Clerk-Recorder within 40 days of starting business. It costs $76 for one name and one registrant, plus $10 for each additional name or registrant; you can start online but finish in person with your original signature. Publish it within 45 days of filing, once a week for four consecutive weeks in a newspaper of general circulation in the county.
- 2
Get your free EIN and any seller's permit
The IRS says you generally need an EIN to hire employees or to operate a partnership or corporation. It issues the number online, immediately if approved, and never charges for it. If you sell or lease goods that would ordinarily be subject to sales tax, you also need a seller's permit from the CDTFA, which does not charge for it but may ask for a security deposit.
- 3
Get your Oxnard Business Tax Certificate
Oxnard issues a Business Tax Certificate instead of a business license. Anyone doing business in the city needs one before starting, whether the business is in Oxnard or outside it, and even with another city's license. A business physically located in Oxnard applies in person so Planning and Zoning can approve it, then renews online; a business based elsewhere can apply by email (CTLicensing@oxnard.org), by mail to 214 South C Street, or by fax, (805) 385-7865, and licensed contractors have their own application. Each location and each type of business needs its own certificate. Licensing: (805) 385-7817; in-person window hours are temporarily 9 a.m. to 1 p.m.
- 4
Confirm zoning and pull any industry permits
Have an exact street address before you go to any agency, since it decides your zoning; a private mailbox address is for mail only. If you sell or serve food: Ventura County Environmental Health issues the Permit to Operate every restaurant and market needs, and state law requires plans approved before a new facility is built or an existing one is remodeled. Plan review is usually needed for new construction, remodels, new or replacement equipment, an ownership change or a menu change: (805) 654-2813. For other permits, GO-Biz offers permitting and regulatory help for any size company.
- 5
Renew every year
Renew before the first day of your business's anniversary month. A business taxed on gross receipts gives a 12-month estimate the first year and proof of receipts at each renewal. Penalties apply to late renewals even if the notice never arrives, and card payments carry a 2.95% service fee.
- 6
Check the $800 California tax rules for your entity
Every California LLC owes the $800 annual tax, even in a year it does no business, until it is cancelled. Corporations owe an $800 minimum franchise tax, but newly incorporated or qualified corporations do not pay it in their first taxable year.
