Summary
Thousand Oaks requires nearly every business, trade, profession, or calling operating in the city to obtain a business tax certificate and pay an annual tax before doing business, regardless of whether the business also needs other permits. The tax is calculated on a sliding gross-receipts scale, starting at $20 for businesses with $15,000 or less in annual receipts and rising with revenue, or at a flat rate for certain categories like solicitors and contractors.
There are hereby imposed upon the business, professions, trades, occupations, and callings set forth in this chapter business taxes in the amounts set forth in this chapter. It shall be unlawful for any person to transact and carry on any business, trade, profession, occupation, or calling in the City without first having procured a business tax certificate from the City so to do and paying the tax set forth in this chapter or without complying with any and all applicable provisions of this Code.
(a) Conflicts with United States and State laws. The provisions of this chapter shall not be construed to require any person to obtain a business tax certificate prior to doing business within the City if such requirement is superseded by applicable laws of the United States or of the State. Any person not required to obtain a business tax certificate prior to doing business within the City nevertheless shall be liable for the payment of the tax imposed by the provisions of this chapter.
(b) Any person not required to obtain a business tax certificate prior to doing business within the City because of conflicts with applicable statutes of the United States or the State shall be liable for payment of the tax imposed by the provisions of this chapter. (§ 2, Ord. 176-NS, eff. December 4, 1970)

Full Breakdown
Under TOMC Chapter 1, operating without first procuring a business tax certificate is unlawful, and the certificate must be renewed and posted at the place of business. The tax itself is a revenue measure, not a regulatory permit: payment doesn't authorize an otherwise-illegal business or excuse compliance with zoning, health, or fire requirements. For businesses taxed on gross receipts, the City uses a bracketed schedule (Sec. 3-1.32) running from $20 at the bottom tier up to $1,070 plus 8 cents per $1,000 over $5,000,000 at the top. Certain occupations instead pay flat annual, quarterly, or per-vehicle rates set out in Sec. 3-1.35 (e.g., contractors, delivery trucks, taxicabs). Limited exemptions exist for disabled veterans, registered charitable/religious/nonprofit activity, and minors or seniors earning under $1,200/year from a part-time occupation.
Violations & Fines
Knowingly operating without a certificate, failing to display one, or misrepresenting information to the Collector is a violation of the Code under TOMC § 3-1.25, enforced via the general penalty provision of Title 1, Chapter 2 § 1-2.01. Delinquent tax also draws a penalty of $10 or 10% of the tax owed (whichever is greater) for each month it goes unpaid.
