Key Audit Assertions for the Income Statement:

1. Occurrence:

   • Transactions and events recorded in the income statement must have actually occurred and pertain to the entity.
   • Example: Sales revenue recorded in the financial statements should correspond to actual sales transactions that have taken place.

2. Completeness:

   • All transactions and events that should have been recorded in the income statement must be included to ensure there are no omissions.
   • Example: All revenue transactions during the period must be captured to avoid understating income.

3. Accuracy:

   • Amounts and other data in the financial statements must be recorded correctly.
   • Example: Sales revenue and expenses should reflect correct amounts, including discounts and tax deductions.

4. Cut-off:

   • Transactions must be recorded in the correct accounting period to avoid misstatements.
   • Example: Sales occurring on December 31 should be included in the current year’s financial statements, while sales on January 1 should be recorded in the following year.

5. Classification:

   • Transactions must be classified into appropriate accounts.
   • Example: Revenue should be recorded under income, not under liabilities or expenses.
