Which of the following is NOT a source of government revenue?

Step 1: Analyze the question We are asked to find the option that is NOT a source of government revenue. Three options will list real ways governments raise money, and one will list things that are not government revenue sources.

Step 2: The concept Government revenue is money the government collects to finance its spending. The main sources are:

• Tax revenue: income tax, company tax, VAT, customs and excise duties
• Non-tax revenue: fees, licences, fines, rents, royalties, interest, dividends, and profits from government-owned enterprises
• External and other sources: grants, aid, and borrowing (loans, bonds, treasury bills)

Step 3: Check each option

• A. Taxes, fees, licences and fines: These are standard government revenue sources. For example, driver's licence fees and court fines are paid to government.
• B. Personal income, disposable income and transfer earnings: These are concepts in household and individual finance. Personal income is what individuals earn, and disposable income is what remains after tax. Transfer earnings is a factor-pricing concept: the minimum payment needed to keep a factor in its current use. None of these is something the government collects as revenue. (Government taxes personal income, but the income itself belongs to individuals.)
• C. Interest, dividends, profits and earnings: Government receives these from its investments and public enterprises, such as shares in companies or earnings from NNPC and other parastatals.
• D. Grants, aids and borrowing: Grants and aid from other countries or international bodies, and loans from domestic or external lenders, all fund government spending.

Step 4: Answer Option B is the only one made up of items that are not government revenue sources.

Tip: In "NOT a source of government revenue" questions, look for the option that describes individual or household money concepts (personal income, disposable income) rather than money flowing into the government. Remember that taxes are the government's revenue, but the income being taxed is not.
