Types of Income

Key Concepts

Income is the amount earned by a business through its activities. It is recorded in the Statement of Financial Performance. There are three types:

TypeWho earns itExamples
Sales revenueTrading businessesSell goods — furniture, clothing, food products
Service fee revenueService businessesProvide services — hair-cutting fees, IT support fees, tutoring fees
Other incomeAny businessRental income, commission income, interest income

Revenue Recognition Theory — Income is recognised when it is earned, regardless of when cash is received:

  • Trading businesses: revenue is recognised when goods are sold to the buyer.
  • Service businesses: service fee revenue is recognised when services have been provided to the customer.

How to Remember

The cash can come before or after the earning. Recognition follows the earning (when goods are sold or services provided), not the cash.

Common Mistakes
1

Listing service fee revenue under "Other income" — Service fee revenue is the primary revenue of a service business and appears as its own line item in the Statement of Financial Performance, not under "Other income."

2

Recording revenue when cash is received — Revenue must be recorded when earned (goods sold / services provided), not when cash is received. This is the revenue recognition theory.

(a) Commission income (other income) — this is not the primary activity of the business; (b) Sales revenue — selling goods is the primary activity of a trading business.
