Service Tax is an indirect tax imposed on specified taxable services in India. It is defined in Section 65B of the Finance Act and excludes certain activities like the sale of goods, money transactions, and services provided by employees. Every provider of taxable services must register for Service Tax by filing Form ST-1 within 30 days. There is a "negative list" of 17 services that are exempt from Service Tax. The goal of Service Tax is to reduce taxes on manufacturing and trade while still generating government revenue.
