State codes form the first part of a registered taxpayer’s GSTIN (Goods and Services Tax Identification Number). State codes play a vital role in determining the place of supply of goods or services, as they help to identify the correct state or union territory where the supply is consumed, and, thus, the correct tax liability and revenue sharing.

This blog will explore how state codes are used to determine the place of supply of goods or services under GST. We will also discuss the legal considerations in using state codes for place of supply, the benefits of streamlining place of supply determination through state codes, and the role of state codes in place of supply compliance.

What is place of supply?

The place of supply is identified as the location of the goods after their movement to the recipient. Once the goods are delivered to the buyer at a specific location, this becomes the deemed place of supply (POS).

State code’s impact on accurate place of supply determination

The place of supply for goods or services is governed by sections 10, 11, 12, and 13 of the IGST Act. While the general rule aligns the place of supply with the delivery location for goods and the recipient’s location for services, exceptions abound.

The state code plays a crucial role in accurate place of supply determination, aiding in identifying the precise state or union territory of consumption. This ensures correct tax rates equitable revenue sharing, and prevents double taxation or evasion.

Incorporating state codes in place of supply calculations

Determining the place of supply for services involves a comprehensive assessment of various factors. These factors play a crucial role in defining the location of supply and, consequently, the applicable tax regulations. Let’s delve into each significant factor influencing the determination of the place of supply.

Type of Service: Defining the Geographic Nexus

The nature of the service provided is a pivotal determinant in establishing the place of supply. Depending on the service category, the location can be attributed to either the supplier or the customer. For instance, services related to real estate tie the place of supply to the property’s location, while consulting services are linked to the customer’s geographic whereabouts.

Location of the Supplier: Geographic Source of Service

The supplier’s geographical location is another critical aspect influencing the place of supply. If the supplier and the customer are situated within the same country, the place of supply is designated as the customer’s location. Conversely, if the supplier operates from a different country, the place of supply is identified as the supplier’s location. State of Codes are important in identifying the supplier’s location and determining the tax levied on the supplier.

Location of the Customer: Geographical Receiver of Services

The customer’s geographical location holds significant weight in determining the place of supply. If both the supplier and the customer are within the same country, the place of supply aligns with the customer’s location. Conversely, when the customer resides in a different country, the supplier’s location becomes the designated place of supply. The state of codes help in identfying the location of the customer and supplier and distinguish between inter-state and intra-state supply. 

Status of the Customer: Impact on Taxation Dynamics

The customer’s status plays a pivotal role in shaping the place of supply for services. The customer’s tax status influences the applicable tax rates and regulations. For instance, if the customer is a non-taxable individual, the place of supply defaults to the supplier’s location. Conversely, for taxable entities like businesses, the place of supply is tied to the customer’s location.

Importance of State of Supply 

  • Misclassifying supplies between interstate and intrastate can lead to hardships for taxpayers under Section 19 of the IGST Act and Section 70 of the CGST Act.
  • Incorrectly paid taxes based on the wrong classification necessitate the taxpayer to initiate a refund claim process.
  • Taxpayers must rectify misclassifications by paying the correct tax amount, considering the revised or corrected classification.
  • Failure to rectify misclassifications to avoid the imposition of interest on the outstanding tax amount.
  • Accurate determination of the place of supply is crucial for understanding the tax incidence associated with a transaction.
  • If the place of supply is correctly identified as outside India, the transaction may be exempt from taxation.
  • Ensures compliance with legal frameworks and contributes to a transparent and fair taxation system.
  • Facilitates the overall efficiency of the GST regime by promoting accurate and fair taxation practices.

Utilising state codes for place of supply determination

State codes play a crucial role in the Goods and Services Tax (GST) system, providing essential information to identify the geographical locations of both suppliers and recipients of goods or services. This identification is vital in determining the accurate place of supply, which, in turn, influences the taxation applied to transactions.

Place of Supply Determination:

State codes contribute to pinpointing the place of supply, representing where goods or services are consumed and where tax revenue is applicable. This determination is pivotal in distinguishing between inter-state and intra-state transactions, dictating the appropriate levies such as IGST or CGST & SGST.

Inclusion in GSTIN:

State codes, represented by a two-digit alphanumeric identifier, are integral components of the Goods and Service Tax Identification Number (GSTIN) assigned to suppliers and recipients. The first two digits denote the country code, while the subsequent digits indicate the state code.

Avoidance of Ambiguity:

The state code eliminates confusion and ambiguity, especially when the locations of the supplier and recipient are unclear. This is particularly significant when place of supply rules are intricate or exhibit variations based on the nature and mode of supply.

Uniform Application of GST:

By incorporating state codes, GST ensures uniformity and consistency in its application across India’s diverse states and union territories. This uniformity facilitates a seamless flow of tax credits and revenue, promoting harmonious taxation practices between states and the central government.


By streamlining place of supply determination through state codes, taxpayers can benefit from the simplicity and clarity of the GST system and reduce the complexity and uncertainty of tax calculation and payment. State codes allow registered taxpayers to assert input tax credits for the taxes paid on their inward supplies by matching their GSTIN with their suppliers’ GSTIN.State codes also facilitate the administration and enforcement of the GST system, as they provide a uniform and transparent mechanism for identifying and verifying the taxpayers and their supplies. Therefore, state codes are a crucial tool for determining the place of supply of goods or services under GST, and they have significant implications for the taxpayers, the tax authorities, and the economy as a whole.

Frequently Asked Questions(FAQs) 

What is the POS rule in GST?

The POS rule in GST, or the Place of Supply rule, designates where the supply is considered an international transaction. If the service recipient’s location is unspecified, the place of supply defaults to that of the supplier.

What is a state code?

A state code in GST is a distinctive code assigned to each state, aiding in identifying regions, provinces, states, and even countries. This code is crucial for accurate determination of the place of supply.
