The Central Sales Tax Act, 1956 provides the legal framework for levying and collecting tax on the sale of goods in the course of inter-state trade or commerce in India. Some key aspects include:
1. It defines terms like "sale", "declared goods", "place of business", and categorizes dealers as registered or unregistered.
2. The Act determines when a sale occurs within a state or inter-state and assigns an "Appropriate State" to administer the tax.
3. It empowers the central government to levy tax according to the tax rates of the Appropriate State and provides for the distribution of tax revenues among states.
