Goods and Services Tax (GST) registration is mandatory for many businesses in India. However, a large number of applications are rejected every year due to avoidable mistakes, incomplete documentation, or lack of proper compliance. A GST rejection not only delays business operations but may also lead to penalties, loss of input tax credit, and legal complications. Most GST rejections happen for predictable, avoidable reasons. Once you know what to watch out for and how to correct it you can reduce your risk dramatically.
