The accountant looks at the customer&#8217;s address, sees another State, and selects IGST. If the customer&#8217;s address appears to be in the same state, CGST and SGST are entered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That approach may work in some straightforward transactions. But it is not the legal test.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under GST law, the nature of the supply is determined through the interaction between the <strong>location of the supplier<\/strong> and the <strong>place of supply<\/strong>, subject to the specific provisions of the IGST Act.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That distinction becomes particularly important for service providers, businesses with registrations in more than one state, supplies involving SEZs, reverse-charge transactions and transactions where the billing address does not tell the whole story.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The issue is therefore not simply an accounting-formatting decision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The tax head on the invoice is a consequence of the legal character of the supply.<\/strong><\/p>\n\n\n\n<h2 id=\"h-1-cgst-sgst-and-igst-are-not-simply-three-ways-of-displaying-gst\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_CGST_SGST_and_IGST_Are_Not_Simply_Three_Ways_of_Displaying_GST\"><\/span>1. CGST, SGST and IGST Are Not Simply Three Ways of Displaying GST<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The first point is worth understanding because it explains everything that follows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">GST in India operates through different statutory and constitutional mechanisms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Article 246A of the Constitution gives Parliament and State Legislatures power to make laws with respect to GST, while Article 269A deals with the levy and collection of GST on supplies taking place in the course of interstate trade or commerce.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CBIC describes the GST structure through three principal components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Central Goods and Services Tax (CGST)<\/strong><\/li>\n\n\n\n<li><strong>State Goods and Services Tax (SGST) \/ Union Territory GST (UTGST)<\/strong><\/li>\n\n\n\n<li><strong>Integrated Goods and Services Tax (IGST)<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The distinction is therefore substantive. It is not merely a matter of putting the same tax into different columns on an invoice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In broad terms:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An <strong>intra-state supply<\/strong> ordinarily attracts CGST together with SGST or UTGST; and<\/li>\n\n\n\n<li>An interstate<strong> supply<\/strong> ordinarily attracts IGST.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The critical question is therefore:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Is the supply intra-state or inter-state?<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">And that question takes us to the place-of-supply provisions.<\/p>\n\n\n\n<h2 id=\"h-2-the-fundamental-test-supplier-s-location-place-of-supply\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_The_Fundamental_Test_Suppliers_Location_Place_of_Supply\"><\/span>2. The Fundamental Test: Supplier&#8217;s Location + Place of Supply<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is where many GST invoicing mistakes begin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an ordinary supply, the supplier should not simply ask:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cWhere is my customer located?\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">The more appropriate starting point is:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Where is the supplier located, and where is the place of supply under the applicable provision of the IGST Act?<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Section 7 of the IGST Act deals with interstate supplies. Section 8 deals with intra-state supplies. Broadly, where the location of the supplier and the place of supply are in different states or union territories, the supply is treated as interstate. Where they are in the same state or union territory, the supply is ordinarily treated as intra-state, subject to the statutory exceptions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This distinction is important because <strong>\u201cplace of supply\u201d is a legal concept<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not necessarily the same thing as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the customer&#8217;s billing address;<\/li>\n\n\n\n<li>the delivery address;<\/li>\n\n\n\n<li>the address printed on the purchase order;<\/li>\n\n\n\n<li>the address from which payment is made; or<\/li>\n\n\n\n<li>the physical location where a particular employee happens to receive an email or service.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The applicable provision of the IGST Act determines the place of supply.<\/p>\n\n\n\n<h2 id=\"h-3-why-the-buyer-s-address-can-sometimes-mislead-you\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Why_the_Buyers_Address_Can_Sometimes_Mislead_You\"><\/span>3. Why the Buyer&#8217;s Address Can Sometimes Mislead You<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Consider a simple example.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A supplier is located in <strong>Rajasthan<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The customer gives a billing address in <strong>Punjab<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It would be tempting to immediately select IGST.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But suppose the applicable place-of-supply provision determines that the place of supply is <strong>Rajasthan<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In that situation, the relevant comparison is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Supplier&#8217;s location:<\/strong> Rajasthan<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Place of supply:<\/strong> Rajasthan<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The supply would ordinarily be intra-state, and CGST + SGST would apply.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CBIC has published precisely this kind of example in its GST FAQ material. Its answer states that where the place of supply and the supplier&#8217;s location are in the same state, the supply is intra-state and CGST\/SGST applies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That leads to an important practical lesson:<\/p>\n\n\n\n<h3 id=\"h-do-not-allow-the-customer-s-billing-address-to-make-the-tax-decision-automatically\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Do_Not_Allow_the_Customers_Billing_Address_to_Make_the_Tax_Decision_Automatically\"><\/span>Do Not Allow the Customer&#8217;s Billing Address to Make the Tax Decision Automatically<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The address may be relevant to determining the place of supply in some transactions.

Other rules apply where goods are installed or assembled, supplied without movement, or supplied on board a conveyance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Services are even more nuanced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Section 12 of the IGST Act contains rules for services where the supplier and recipient are located in India, with specific provisions for different categories of services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That means the correct sequence is not:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Customer address \u2192 choose tax head.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Identify the supply \u2192 determine the supplier&#8217;s location \u2192 identify the applicable place-of-supply rule \u2192 determine the place of supply \u2192 determine whether the supply is intra-state or inter-state \u2192 select the appropriate tax head.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is a much safer way to approach GST invoicing.<\/p>\n\n\n\n<h2 id=\"h-5-a-gst-invoice-should-record-the-legal-reasoning-not-hide-it\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_A_GST_Invoice_Should_Record_the_Legal_Reasoning_Not_Hide_It\"><\/span>5.

Which GSTIN Is Making the Supply?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This establishes the relevant supplier registration\/location.<\/p>\n\n\n\n<h3 id=\"h-2-what-is-the-place-of-supply-under-the-igst-act\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_What_Is_the_Place_of_Supply_Under_the_IGST_Act\"><\/span>2. What Is the Place of Supply Under the IGST Act?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is a legal determination and may vary according to the nature of the transaction.<\/p>\n\n\n\n<h3 id=\"h-3-are-the-supplier-s-location-and-place-of-supply-in-the-same-state-or-different-states\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Are_the_suppliers_location_and_place_of_supply_in_the_same_state_or_different_states\"><\/span>3. Are the supplier&#8217;s location and place of supply in the same state or different states?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">That comparison generally determines whether the supply is intra-state or inter-state, subject to the statutory exceptions.<\/p>\n\n\n\n<h2 id=\"h-conclusion-cgst-vs-sgst-vs-igst-is-a-legal-classification-not-an-invoice-formatting-choice\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion_CGST_vs_SGST_vs_IGST_Is_a_Legal_Classification_Not_an_Invoice-Formatting_Choice\"><\/span>Conclusion: CGST vs SGST vs IGST Is a Legal Classification, Not an Invoice-Formatting Choice<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The distinction between <strong>CGST + SGST\/UTGST and IGST<\/strong> is rooted in the structure of India&#8217;s GST legislation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The safest approach is therefore not to ask:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cWhere is my customer?\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">but:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>\u201cWhich GST registration is making the supply, what is the applicable place-of-supply rule, and where does that rule place the supply?\u201d<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">CBIC&#8217;s published material makes the central principle clear: the comparison between the <strong>location of the supplier<\/strong> and the <strong>place of supply<\/strong> is fundamental to determining whether a supply is intra-state or inter-state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For businesses, the practical discipline is simple:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Identify the GSTIN.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Identify the nature of the supply.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Determine the place of supply.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Then select the tax head.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That small change in the invoicing process can prevent a surprisingly large number of GST disputes, reconciliation problems and input-tax-credit complications.<\/p>\n\n\n\n<h2 id=\"h-frequently-asked-questions\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 id=\"h-is-gst-charged-as-cgst-and-sgst-or-igst\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_GST_charged_as_CGST_and_SGST_or_IGST\"><\/span>Is GST charged as CGST and SGST or IGST?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ordinarily, an intra-State supply attracts CGST with SGST or UTGST, while an inter-State supply attracts IGST. The determination depends on the statutory classification of the supply and the applicable place-of-supply provisions.<\/p>\n\n\n\n<h3 id=\"h-does-the-customer-s-billing-address-determine-whether-igst-applies\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Does_the_Customers_Billing_Address_Determine_Whether_IGST_Applies\"><\/span>Does the Customer&#8217;s Billing Address Determine Whether IGST Applies?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. The billing address alone is not the universal test. The supplier&#8217;s location and the legally determined place of supply must be considered under the IGST Act.<\/p>\n\n\n\n<h3 id=\"h-what-is-the-difference-between-cgst-sgst-and-igst\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_the_Difference_Between_CGST_SGST_and_IGST\"><\/span>What Is the Difference Between CGST, SGST and IGST?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CGST is the central tax component applicable to intra-state supplies; SGST\/UTGST is the corresponding state\/union territory component; and IGST applies to inter-state supplies and certain other supplies treated as inter-state under the IGST Act.<\/p>\n\n\n\n<h3 id=\"h-if-the-customer-is-in-another-state-is-igst-always-applicable\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"If_the_customer_is_in_another_state_is_IGST_always_applicable\"><\/span>If the customer is in another state, is IGST always applicable?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not necessarily merely because the customer&#8217;s address is in another state. The applicable place-of-supply provision must first be examined. The legal comparison is between the supplier&#8217;s location and the place of supply.<\/p>\n\n\n\n<h3 id=\"h-does-an-sez-transaction-require-special-gst-treatment\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Does_an_SEZ_Transaction_Require_Special_GST_Treatment\"><\/span>Does an SEZ Transaction Require Special GST Treatment?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Supplies to or by an SEZ developer or SEZ unit are specifically treated under the IGST Act, and supplies to SEZs are dealt with as zero-rated supplies subject to the applicable statutory requirements.<\/p>\n\n\n\n<h3 id=\"h-what-should-i-do-if-i-charged-cgst-and-sgst-when-igst-should-have-been-charged\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Should_I_Do_if_I_Charged_CGST_and_SGST_When_IGST_Should_Have_Been_Charged\"><\/span>What Should I Do if I Charged CGST and SGST When IGST Should Have Been Charged?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Do not simply alter or replace the invoice without examining the applicable GST provisions and the correction mechanism. The consequences can extend to the supplier&#8217;s tax liability, reporting and the recipient&#8217;s input-tax-credit position.<\/p>\n\n\n\n<h2 id=\"h-legal-and-compliance-note\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Legal_and_Compliance_Note\"><\/span>Legal and Compliance Note<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This article is intended for general educational and informational purposes.
