CA stands for Chartered Accountant. It is a professional designation in the field of finance and refers to a financial professional who is qualified to execute certain accounting procedures. The CA designation is granted internationally to individuals aside from the United States, and it is the same as the certified public accountant (CPA) designation in the United States. Chartered Accountants work in four main areas, including applied finance, financial accounting and reporting, management accounting, and taxation. Their responsibilities may include filing taxes and auditing financial statements.
