Interest definition clarifies taxable and excluded components, including commitment charges, discounts on bills, and treated dividends. The document defines interest for taxation: it covers amounts payable in respect of moneys borrowed or debt incurred, including service fees, charges related to borrowed moneys or debt, and charges for unutilised credit facilities; an explanation treats dividend as interest for a specified anti-avoidance provision. The interest-tax definition includes commitment charges on unutilised credit and discounts on promissory notes and bills, while excluding certain statutory categories and treasury bill discounts.
