Dear Sir/ madam One of my client is having a business of trading of F & O .Now I want to check that the client's turnover is falling under tax audit or not. Please let me know how to calculate turnover ? Is difference between sell or buy of securities and futures and options taken as turnover or gross value of sell of securities and futures and options taken as turnover ?
