Years ago, India had many different taxes in every state. It was like having to use different currencies just to move goods across the country. This made things expensive and confusing for everyone. The government brought in GST, which is one single tax for the whole country. Everything is now tracked on computers. Because of this, the money collected in March grew by 8.2% to reach ₹1.78 lakh crore.Think of this as a big "Piggy Bank" for the country. When it stays full, the government can build faster trains, better roads, and free hospitals without running out of money.
