Income types for businesses


You must report all income that your business earned during a tax year. Depending on a type of income, it may be taxable.

Generally, income earned by a business in connection with its regular trade or business is subject to California tax if the business has sufficient contact with the State. Common income types that may be subject to tax include income from sales of goods, provision of services, rental income, and interest/dividend income.

Visit Apportionment and allocation if you also do business outside of California.

Gross income

Gross income is gross receipts minus returns and allowances, minus costs of goods sold. Generally, gross receipts is all revenue that your business received during a given year from:

  • Sales of goods
  • Provision of services
  • Other income producing assets or activities

Calculate gross receipts by adding all revenue received within a tax year without subtracting returns, allowances, costs of goods sold, or any other business expenses.
