Which of the following is NOT a function of money?

Money serves several important functions within an economy, primarily acting as a store of value, a unit of account, and a medium of exchange.

A store of value means that money can hold and preserve value over time, allowing individuals to save and plan for future purchases. This function is essential because it enables people to defer consumption until a later date without losing value.

As a unit of account, money provides a consistent measure for pricing goods and services, making it easier to compare their value. This function simplifies transactions as consumers can easily understand the worth of items in monetary terms.

The medium of exchange function allows money to facilitate transactions between buyers and sellers, making it easier to trade goods and services than barter systems, which require a double coincidence of wants.

In contrast, managing tax obligations is not a core function of money itself. While money may be used to pay taxes, the responsibility and system surrounding taxation are governed by laws and regulations established by governments, rather than being inherent to the nature of money. Therefore, the correct response identifies a function that does not align with the foundational roles that money plays in the economy.
