Commerce QUESTION #6061

Question 4900

A house building advance of Rs. 2 million is paid to employees. In accounting terms, this payment is classified as a:

Asset✔️
Revenue Expenditure
Capital Expenditure
Deferred Revenue Expenditure

Correct Answer Logic:

An advance paid to employees (such as a house-building advance) creates a receivable for the organization — the employee owes the money back. It is therefore recorded as an Asset (specifically a long-term receivable or loan to employees) on the balance sheet. It is not an expense until it is written off or adjusted, so it is neither revenue expenditure nor capital expenditure in the traditional sense.
