GST registration, short for Goods and Services Tax registration, is a mandatory requirement in many countries, including India, for businesses that meet specific turnover thresholds. This process involves registering a business entity with the tax authorities to collect and remit GST on the sale of goods and services. Once registered, a business is issued a unique GST identification number, enabling them to engage in lawful commercial activities. Compliance with GST regulations is essential to avoid penalties and legal consequences, and it also facilitates input tax credit claims, making it crucial for businesses to navigate this process effectively.
