    What is profit after tax?

    Profit after tax, also known as net profit, is a familiar concept in the field of corporate finance and accounting. Although this is an important indicator in evaluating business performance, the law currently does not have specific and uniform regulations on how to calculate after-tax profit.

    In essence, profit after tax is the remaining income of the enterprise after deducting all expenses related to production and business activities, including corporate income tax. On financial statements, this indicator is often expressed as “net profit” and serves as the main measure of the final financial performance of the business in an accounting period.

    A higher profit after tax indicates that the business is operating efficiently and is able to create real value after completing its tax obligations.

    In addition, in financial analysis, people often use the Net Profit Margin index – which is calculated as a percentage between net profit and net revenue. This is an important tool to help assess the profitability per dollar of revenue, thereby reflecting the ability to control costs and business efficiency of enterprises.
