Sales Tax Registration is mandatory for any business entity engaged in the sale of goods in India. No VAT is levied on goods exported from India. VAT is collected and governed by the State Government. So each State Government in India has distinct rules applicable for their State based on the type of good manufactured or sold.
Sales Tax Registration is required if the annual turnover of the business crosses Rs. 5 lakhs in most states, though some have raised this threshold limit to Rs. 10 lakhs. When registered for VAT/Sales Tax, the manufacturer or trader is allotted with a unique 11 digit number which will serve as the TIN Number for the business.
