Goods and Services Tax (GST) is one of the most significant reforms in Indian taxation, designed to simplify indirect taxes and create a uniform tax system. However, many businesses, especially small and medium enterprises, face challenges in staying compliant. Mistakes in GST compliance can lead to penalties, delayed refunds, and unnecessary legal scrutiny.

In this blog, we’ll discuss common GST errors businesses make and provide tips to avoid them effectively.
