Late GST Registration penalty

You are required to register once your turnover crosses the ₹20 lakh (or ₹10 lakh) threshold. While you may face a general penalty for late registration, you do not owe tax on your past "zero-rated" exports because the tax rate is 0%. Ensure your services meet the legal definition of "export of services" to avoid being classified as a taxable domestic service. Registering as soon as possible is the best way to mitigate future issues.
