Q.State any four objectives that GST was designed to achieve.

GST's objectives all trace back to fixing the fragmentation and cascading that defined the pre-GST structure.

Any four of these six, correctly stated, is a complete answer.

GST was designed with several linked objectives in mind:

1. Eliminate the cascading effect of taxation ('tax on tax'), through a seamless input tax credit chain.
2. Create one unified national market, removing State-level tax barriers (like Entry Tax/Octroi at State borders) that fragmented trade.
3. Simplify compliance, replacing multiple taxes, returns, and authorities with a single tax, return system, and portal.
4. Broaden the tax base and reduce tax evasion, through invoice-matching and the input-credit mechanism.
5. Boost overall economic growth and ease of doing business, by lowering compliance and logistics costs and removing inter-State tax friction.
6. Harmonise Centre-State tax administration, through the GST Council as a joint constitutional forum for rate-setting and rule-making.

Any four of these six, clearly stated, fully answers the question.

Students sometimes state 'to increase government revenue' as GST's primary objective — while GST does aim to broaden the tax base and reduce evasion (which can raise revenue), the syllabus's own framing centres on removing cascading, unifying the market, and simplifying compliance, not revenue maximisation as the stated goal.
