Sec. 29.
"Business Income" Defined. "Business Income" is defined in the Act as income from transactions and activity in the regular course of the taxpayer's trade or business, including income from tangible and intangible property if the acquisition, management, or disposition of the property are integral parts of the taxpayer's regular trade or business.
Nonbusiness income means all income other than business income.
The classification of income by the labels occasionally used, such as manufacturing income, compensation for services, sales income, interest, dividends, rents, royalties, gains, operating income, non-operating income, etc., is of no aid in determining whether income is business or nonbusiness income. Income of any type or class and from any source is business income if it arises from transactions and activity occurring in the regular course of a trade or business. Accordingly, the critical element in determining whether income is "business income" or "nonbusiness income" is the identification of the transactions and activity which are the elements of a particular trade or business.
