GST is a single tax on the supply of goods and services, right from the manufacturer to the consumer. Credits of input taxes paid at each stage will be available in the subsequent stage of value addition, which makes GST essentially a tax only on value addition at each stage. The goods and services tax (GST) is a tax on goods and services sold domestically for consumption. The tax is included in the final price and paid by consumers at point of sale and passed to the government by the seller. The GST is usually taxed as a single rate across a nation.
