What is GST?
The Goods and Services Tax (GST) is a unified indirect tax system introduced in India to replace multiple taxes such as VAT, Service Tax, Excise Duty, and Central Sales Tax. It simplifies taxation by creating one single tax across the country.
Who Needs GST Registration?
Any business with an annual turnover exceeding Rs 20 lakhs (Rs 10 lakhs for special category states) must register for GST. E-commerce sellers, inter-state suppliers, and businesses providing taxable services also require registration regardless of turnover.
