GST registration in India is free when you apply directly through the official GST portal (gst.gov.in). The government does not charge any registration fee—whether you are applying as a sole proprietor, partnership, LLP, or company. You only need to complete the form, upload required documents, and submit the application online.
However, many businesses choose professional help to ensure the process is smooth, error-free, and compliant. In that case, there may be service charges from the provider you choose.
