Tax policy refers to the guidelines and principles established by a government for the imposition and collection of taxes. It encompasses both microeconomic and macroeconomic aspects. The former focuses on issues of fairness and efficiency in tax collection, and the latter focuses on the overall quantity of taxes to be collected and its impact on economic activity. The tax framework of a country is considered a crucial instrument for influencing the country's economy.
Tax policies have significant implications for specific groups within an economy, such as households, firms, and banks. These policies are often intended to promote economic growth; however, there is significant debate among economists about the most effective ways to achieve this.
