Summary

National City puts every business into a tax class under § 6.04.220. A business takes its class from the rate classification schedule, unlisted businesses take the closest Standard Industrial Classification match, and a business that fits two classes is taxed under the one with the highest dollar volume, or the highest tax if volumes tie.

A.The classification of a particular business shall be that classification set forth in the business tax rate classification schedule designated in Section 6.04.030(B). When a particular type of business cannot be located on that schedule, the collector shall assign to it the tax rate classification most closely corresponding to the business's standard industrial classification number ("SIC" number) from the most current Standard Industrial Classification Manual published by the U.S. government, a copy of which shall be kept on file in the collector's office.B.Any business classifiable under two or more classification schedules shall be classified on the basis of the business classification with the highest dollar volume of business; if the business dollar volume is equal, however, it shall be classified on the basis of the business classification which will result in the highest tax.

Full Breakdown

Section 6.04.220 of the National City Municipal Code gives the collector two rules for classification. First, the class is the one set forth in the business tax rate classification schedule designated in § 6.04.030(B). When a business type is not on that schedule, the collector assigns the class most closely matching the business's Standard Industrial Classification number from the most current manual published by the U.S. government, and a copy is kept on file in the collector's office. Second, a business classifiable under two or more schedules is classified by the class with the highest dollar volume of business. If the volumes are equal, the class producing the highest tax controls.

Section 6.04.230 applies classification to multiple activities. Tax is calculated separately for each business location and for each business name at one location, and separate licenses are issued. Similar businesses under one name at one location, the code's example being retail and wholesale auto parts, are taxed on total gross receipts using the schedule of the class with the highest receipts. Dissimilar businesses at one address, such as retail auto parts and automobile repair, or a restaurant and an amusement arcade, are classified separately and the taxes combined. A business with a principal office in National City that runs facilities elsewhere is taxed on its cost of doing business at that office as the measure of gross receipts.

Once classified, § 6.04.280 sets the tax from the classification schedule and the Gross Receipts Tax Table in Appendix B. A new business pays a first-year tax of $20, the minimum annual tax, prorated by quarter, and the second year is based on first-year gross receipts (§ 6.04.270). Annual taxes are due January 1 and delinquent March 1 (§ 6.04.290). Flat alternatives exist for vehicles ($25 per vehicle, or $75 for food vending), swap meets ($4,500 per year), pawnshops ($150) and amusement arcades ($100), each with a binding election for gross receipts (§§ 6.04.310, 6.04.330).

A person aggrieved by a classification or tax decision files a notice of appeal with the collector within 90 days of notification and pays the processing fee in the National City Fee Schedule. The city treasurer sets a hearing within 30 days of receiving the appeal, and the fee is refunded only if the appellant wins wholly (§ 6.04.160).

Violations & Fines

Conducting business in National City without a valid business tax license is unlawful (§ 6.04.260(A)). A business that understates gross receipts by more than five percent can be charged the city's actual audit costs (§ 6.04.150). A business that fails to file has its tax estimated by the collector, at the highest gross receipts tax for its category if records are missing (§ 6.04.300). Missing the 90-day appeal window makes the determination final and bars judicial review (§ 6.04.160).

Frequently Asked Questions

How does National City classify a business not on the rate schedule?
Under § 6.04.220(A), the collector assigns the classification most closely corresponding to the business's Standard Industrial Classification number from the most current manual published by the U.S. government. A copy is kept on file in the collector's office, and the rate schedule itself is designated in § 6.04.030(B).
What if my National City business fits two classifications?
Section 6.04.220(B) classifies the business under the schedule with the highest dollar volume of business. If the dollar volume is equal, the business is classified under the class that results in the highest tax. Dissimilar activities at one address are classified separately under § 6.04.230(B)(2).
Do I need a separate license for each location or business name?
Yes. Section 6.04.230(A) requires the tax to be calculated separately for each business location and for each business name at the same location. Separate business tax licenses are issued for each location and for each separate business name at that location.
How do I appeal a business tax classification decision in National City?
File a notice of appeal or request for dispute resolution with the collector within 90 days of notification and pay the appeal processing fee in the National City Fee Schedule. The city treasurer fixes a hearing within 30 days of receiving the appeal, and a written decision follows within 15 days of the examiner's report (§ 6.04.160).
