Explain three unique of tax from other sources of government revenue.

1. Taxation is a compulsory form of revenue, meaning that it must be paid by individuals and businesses regardless of their financial situation. This is in contrast to other forms of government revenue, such as grants and donations, which are voluntary.

2. Taxes are progressive, meaning that those with higher incomes pay a higher rate of tax than those with lower incomes. This is in contrast to other forms of government revenue, such as user fees, which are typically regressive, meaning that those with lower incomes pay a higher rate than those with higher incomes.

3. Taxes are collected by the government and are used to fund public services and infrastructure. This is in contrast to other forms of government revenue, such as borrowing, which is used to finance government spending.
