GST Registration in Mumbai
If you are running a business in Mumbai, you have probably heard about GST registration. GST stands for Goods and Services Tax. It is a single tax charged when goods are sold or services are provided. Any business with annual sales exceeding ₹40 lakhs (for goods) or ₹20 lakhs (for services) is required to register. Even smaller businesses, such as e-commerce sellers, agents, or those supplying goods across state lines, are required to register.
The process is fully online, so you don’t need to stand in queues or visit offices. You just need simple documents, such as your PAN, Aadhaar, business proof, and bank details. After obtaining a GST registration in Mumbai, your business will be assigned a unique GST number. This number allows you to charge GST to your customers and also claim back the GST you pay on purchases.
What is GST?
GST means Goods and Services Tax. It is just one tax that you pay when you sell goods or give services. Earlier, there were various taxes, including VAT, excise, and service tax. People had to pay them separately to different departments, which was very confusing. In 2017, the government removed all the old taxes and introduced GST. Now, instead of paying 5–6 different taxes, you only pay GST, which is much simpler.
There are four kinds of GST:
- CGST is paid to the central government when you sell something inside your own state.
- SGST goes to the state government at the same time, for the same sale.
- IGST is used when goods or services move between states or when importing or exporting.
- UTGST works like SGST, but only in Union Territories.
