Direct versus indirect taxes, the boards (CBDT and CBIC), key tax terms (progressive, regressive, proportional, buoyancy, evasion versus avoidance, cess and surcharge), the GST architecture (101st Amendment, 1 July 2017, dual GST, CGST/SGST/IGST/UTGST, slabs, input tax credit), the GST Council under Article 279A and its voting, what is outside GST, and the security angle for CAPF Paper I
A tax is a compulsory payment to the Government with no direct quid pro quo. Taxes are split into direct taxes (borne by the person on whom they are levied) and indirect taxes (passed on to the final consumer). The Goods and Services Tax (GST), launched on 1 July 2017 through the 101st Constitutional Amendment Act, 2016, is the single biggest indirect-tax reform in independent India; it replaced a web of central and state indirect taxes with one destination-based value-added tax. CAPF tests the direct-versus-indirect distinction, the two revenue boards (CBDT and CBIC), the GST architecture, the GST Council under Article 279A, the slabs, and what stays outside GST. The standard references are the Constitution (101st Amendment, Article 279A), the GST Acts, the Economic Survey, the Budget documents, and Ramesh Singh's "Indian Economy".
Direct taxes are levied on income or wealth and cannot legally be shifted to another person. The impact and the incidence fall on the same person.
Indirect taxes are levied on goods and services; the impact falls on one person (the seller) but the incidence is shifted to the consumer in the price.
GST is a destination-based, multi-stage value-added tax on the supply of goods and services, with credit for tax paid at earlier stages (input tax credit, ITC), which removes the cascading "tax on tax" effect. Tax accrues to the State where the goods or services are finally consumed, not where they are produced.
On an intra-state sale, CGST and SGST apply together; on an inter-state sale or import, IGST applies.
The main rate slabs are 0, 5, 12, 18, and 28 percent, with a compensation cess on certain luxury and demerit goods (tobacco, aerated drinks, large cars). The slab structure is reviewed periodically by the GST Council and is a recurring re-verify item, so check the latest rate-rationalisation before the exam.
Petroleum crude, petrol, diesel, aviation turbine fuel and natural gas (constitutionally within GST but not yet notified, so taxed under the old regime for now), alcohol for human consumption (kept out by the Constitution), and electricity remain outside GST.
GST subsumed a long list of central and state indirect taxes, removing the cascading and the multiplicity of rates:
| Subsumed central taxes | Subsumed state taxes |
|---|---|
| Central Excise Duty | State VAT / Sales Tax |
| Service Tax | Central Sales Tax |
| Additional and Special Customs duties (CVD, SAD) | Entry Tax and Octroi |
| Central surcharges and cesses on goods/services | Luxury Tax, Entertainment Tax (except local-body levies) |
The reform was based on the work of the Empowered Committee of State Finance Ministers over many years, and required the 101st Constitutional Amendment to give both the Centre and the States concurrent power to tax goods and services (the new Article 246A).
For a broad sense of where Union tax revenue comes from:
| Tax | Type | Board |
|---|---|---|
| Goods and Services Tax | Indirect | CBIC |
| Corporate tax | Direct | CBDT |
| Personal income tax | Direct | CBDT |
| Union excise (mainly petroleum) | Indirect | CBIC |
| Customs duty | Indirect | CBIC |
In recent years direct and indirect taxes have contributed broadly comparable shares of central gross tax revenue; treat the exact split as currency-sensitive and verify against the latest Budget at a Glance.

Adam Smith's four canons of taxation, occasionally tested:
Two related ideas:
The Laffer curve is the idea that beyond a point, raising tax rates reduces revenue because it discourages activity and encourages evasion, which is why rate rationalisation can sometimes raise collections.
A broad, well-collected tax base is the financial foundation of state capacity, funding the defence budget, the central armed police forces, and border-area development (see budget and fiscal policy). The shift to GST and Direct Benefit Transfer reduces cash transactions and leakage, improving the traceability of money flows, which assists anti-money-laundering and counter-terror-financing work. Customs administration (CBIC) is also a frontline internal-security function: it interdicts smuggling, narcotics, fake currency, and the illicit movement of arms and gold across borders, working alongside the central armed police forces at ports and land customs stations. GST's common digital trail (GSTN, e-way bills, e-invoicing) makes large-scale tax fraud and shell-company networks easier to detect.
GST was introduced in India with effect from: a) 1 April 2016 b) 1 July 2017 c) 1 January 2017 d) 1 April 2017 Answer: b. GST came into force on 1 July 2017, through the 101st Amendment of 2016.
On an inter-state supply of goods, the tax levied is: a) CGST and SGST b) only SGST c) IGST d) UTGST Answer: c. IGST applies to inter-state supply and imports, collected by the Centre and apportioned.
The GST Council is a constitutional body established under: a) Article 246A b) Article 279A c) Article 269A d) Article 280 Answer: b. Article 279A; it is chaired by the Union Finance Minister.
In GST Council decisions, the weight of the Centre's vote and the States' combined vote is: a) half and half b) one-third and two-thirds c) two-thirds and one-third d) one-fourth and three-fourths Answer: b. The Centre has one-third, the States together two-thirds, with a three-fourths majority needed.
Which of the following is outside the GST net? a) cement b) ready-made garments c) petrol and diesel d) packaged food Answer: c. Petroleum products, alcohol for human consumption, and electricity remain outside GST.
"Direct can't be Diverted (the payer bears it); Indirect is Imposed onward (shifted to the buyer)." For GST: "Two-7-9-A" is the Council's Article (279A); "C plus S inside a State, I between States". Slabs: "Zero, 5, 12, 18, 28."
Monthly gross GST collections crossing record levels are a regular current-affairs hook, often cited as a sign of formalisation and compliance. The GST Council periodically rationalises slabs and brings items in or out; treat the current slab structure and any rate-rationalisation as currency-sensitive and verify against the latest GST Council communiqué and the Union Budget. Personal income-tax slab changes and the choice between the old and new tax regimes are announced in the Budget each year.
