GST registration is a legal process that gives businesses a unique identity and establishes their legitimacy. Since its implementation on 1st July 2017, the Goods and Services Tax (GST) has been recognized as the most significant tax reform in the country. Earlier, businesses had to deal with multiple indirect taxes like Service Tax, Excise Duty, VAT, Central Sales Tax, Entertainment Tax, and Luxury Tax, which made compliance complex and time-consuming. With the introduction of GST, all these taxes were unified into a single system, making the tax structure simple, transparent, and business-friendly. GST registration is mandatory for traders, service providers, manufacturers, and freelancers whose turnover crosses the threshold limit set by the government. Getting registered under GST not only ensures legal compliance but also enhances business credibility and builds trust among customers. GST has reinforced the vision of “One Nation, One Tax” by eliminating the earlier multi-layered taxation system. This has simplified tax compliance, reduced chances of tax evasion, and minimized the burden of indirect taxation. For businesses, GST has made operations easier and more efficient, while also helping the government maintain stable revenue and strengthen the economy.
