GST Registration
Businesses with an annual turnover exceeding ₹40 lakhs (₹20 lakhs for certain states) are required to register for GST. Some businesses may need to register regardless of turnover, such as those making inter-state supplies or selling through e-commerce platforms.
Input Tax Credit
One of the key benefits of GST is the provision for Input Tax Credit (ITC). Businesses can claim credit for the tax paid on inputs used in the course of business, which helps in avoiding double taxation and reduces the tax burden.
