Full form of VAT is Value Added Tax

A consumption based tax applied at each stage of the supply chain where value is added to goods or services. Businesses collect it on behalf of the government when selling products, while also receiving credit for the tax paid on their own purchases. This mechanism ensures that the final tax burden is ultimately borne by the end consumer rather than intermediaries.

It is widely used across many countries as a structured and transparent way to generate government revenue. Unlike single point sales taxes, it is collected incrementally, which helps reduce tax evasion and improves compliance. Businesses must maintain proper records of input and output taxes to calculate their net liability accurately.

Its importance lies in its efficiency and fairness in taxation. By linking tax collection to each stage of production and distribution, it creates a traceable system that supports public finances while minimizing cascading tax effects on goods and services.
