Withholding tax on dividends and interest applies to non-resident non-corporates under specified statutory rates and conditions. Section 115A imposes a special withholding tax regime on non-resident non corporates and foreign companies for income by way of dividends, interest, royalty and fees for technical services at prescribed rates for distinct categories. It prohibits deductions under sections 28-44C and section 57 for computing such income, limits chapter VIA benefits (with narrow exceptions), exempts filing where income consists only of specified dividend/interest with TDS, and permits set off and carry forward of losses except unabsorbed depreciation; definitions for key terms are cross referenced.
