Restrictions on Taxation of Sale or Purchase in Inter-State Trade

Inter-state trade taxation is constrained by Article 286 of the Constitution, which stops a State from taxing the sale, purchase, or supply of goods and services that are not actually completed within its own borders. The provision exists to stop States from taxing transactions that cross their boundaries or that form part of India's foreign trade, keeping the country's internal market free of overlapping and cascading State taxes.

What Article 286 Says

Article 286(1) bars any State law from imposing, or authorising the imposition of, a tax on the supply of goods or services where that supply takes place (a) outside the State, or (b) in the course of the import of goods or services into, or the export of goods or services out of, the territory of India. Article 286(2) empowers Parliament to lay down, by law, the principles for determining when a supply falls into either of these two categories — that is, when a transaction should be treated as "outside the State" or as import/export, rather than as a purely local sale.

The original text of Article 286 spoke of the "sale or purchase of goods." The Constitution (One Hundred and First Amendment) Act, 2016 — the amendment that introduced the Goods and Services Tax — replaced this with "supply of goods or of services or both," bringing service transactions within the same restriction and aligning the provision with the GST framework. The same amendment also omitted clause (3), which had earlier allowed Parliament to place further restrictions on State taxation of essential goods. Article 286 had already been reworked once before, by the Constitution (Sixth Amendment) Act, 1956, which removed an explanation attached to clause (1), and by the Constitution (Forty-sixth Amendment) Act, 1982, which substituted the earlier clauses (2) and (3).

How This Fits with Union Taxation of Inter-State Trade

Article 286 tells States what they cannot tax; Articles 269 and 269A describe who taxes inter-state supply instead. Under Article 269, taxes on the sale or purchase of goods (other than newspapers) and on the consignment of goods, where the transaction takes place in the course of inter-State trade, are levied and collected by the Union but assigned to the States — a rule in force from 1 April 1996, with the proceeds distributed among States according to principles that Parliament frames by law. Since the 101st Amendment, Article 269A performs the equivalent role for GST: the Integrated Goods and Services Tax (IGST) on inter-State supply is levied and collected by the Union and apportioned between the Union and the States on the recommendation of the GST Council.

The Wider Free-Trade Framework: Articles 301–304

Article 286 operates alongside Part XIII of the Constitution, which protects freedom of trade across India more broadly. Article 301 declares that trade, commerce and intercourse throughout India shall be free — a guarantee meant to dismantle the kind of inter-provincial trade barriers that existed before Independence, and one that covers intra-State as well as inter-State movement of goods, subject to the exceptions that follow it.

Article 302 lets Parliament impose reasonable restrictions on this freedom of trade "as may be required in the public interest." Article 303 then limits both Parliament and State legislatures: neither may use their power over any entry relating to trade and commerce to give preference to one State over another, or to discriminate between States — except that Parliament may do so if it declares such a law necessary to deal with a situation of scarcity of goods in some part of the country. Article 304 permits a State legislature to tax goods imported from other States or Union territories, but only at the same rate as it taxes similar goods produced within the State, so that local production is not favoured over goods coming from elsewhere; a State legislature may also impose reasonable restrictions on trade with or within the State in the public interest, though a Bill of this kind can be introduced only with the President's previous sanction.

The Bengal Immunity Case

The scope of a State's power to tax inter-State sales was tested directly in Bengal Immunity Co v State of Bihar (1955). The Supreme Court in this case overruled its own earlier majority ruling in State of Bombay v United Motors (1953), which had allowed a State where goods were delivered for consumption to tax their sale or purchase even though the transaction took place in the course of inter-State trade or commerce. In doing so, the Court also made clear that it was not bound by its own prior decisions — a point of judicial procedure that has continued to matter in later constitutional cases. The ruling narrowed the taxing reach of States over inter-State transactions and reinforced the restriction that Article 286 was designed to enforce.

Why the Restriction Matters

Without Article 286, a State could tax goods merely passing through it, or goods destined for or arriving from abroad, creating multiple, overlapping tax claims on a single transaction. This would fragment India's internal market along State lines and burden inter-State and foreign trade with unpredictable costs. By confining State taxation to sales and supplies genuinely completed within the State, Article 286 keeps taxing rights aligned with the place where a transaction is truly rooted, while inter-State and international components of trade remain the Union's domain — first through Article 269, and now, for most goods and services, through the unified GST structure under Article 269A.

UPSC Relevance

Prelims

• Article 286 falls under Part XII (Finance, Property, Contracts and Suits) of the Constitution.
• The 101st Amendment (2016) changed "sale or purchase of goods" to "supply of goods or of services or both" in Article 286.
• Bengal Immunity Co v State of Bihar (1955) overruled State of Bombay v United Motors (1953).

Mains

• Examine how Articles 286, 269 and 269A together allocate taxing powers over inter-State trade between the Union and the States.
• Discuss how Part XIII (Articles 301–304) balances the freedom of inter-State trade with States' regulatory and taxing interests.

FAQ

Q1. What does Article 286 of the Constitution prohibit? It prohibits a State from taxing, or authorising a tax on, the supply of goods or services that takes place outside that State, or in the course of import into or export out of India.

Q2. Did GST change Article 286? Yes. The 101st Amendment Act, 2016 replaced "sale or purchase of goods" with "supply of goods or of services or both" and removed clause (3), aligning the Article with the GST regime.

Q3. Who taxes inter-State sales if States cannot? Before GST, Article 269 let the Union levy and collect such taxes and assign the proceeds to States. Since GST, Article 269A performs this role through IGST, apportioned via the GST Council.

Q4. What did the Bengal Immunity case decide? It held that a State could not tax a sale or purchase of goods delivered for consumption within it if the transaction was part of inter-State trade, overruling the earlier State of Bombay v United Motors ruling.

Q5. How does Article 286 relate to Articles 301–304? Article 286 restricts State taxation of inter-State/import-export supply, while Articles 301–304 protect the broader freedom of trade and commerce across India, subject to reasonable, non-discriminatory restrictions.

Quick Revision

• Article 286: States cannot tax supply outside the State, or import/export supply.

• Article 269A: IGST — Union collects, apportioned via GST Council.
• Article 301: freedom of trade, commerce and intercourse throughout India.
• Article 304: States may tax imported goods only at par with local goods; restrictive Bills need President's sanction.
