Introduction

Under India’s indirect tax framework, particularly in the Goods and Services Tax (GST) era, the distinction between inter-state and intra-state transactions plays a central role in determining tax treatment. While Service Tax previously governed services, the introduction of GST brought with it a unified tax structure with clear rules for inter-state services. The Integrated Goods and Services Tax (IGST) governs inter-state supply of services, making compliance more streamlined yet crucial for service providers and recipients. Understanding these rules is essential for businesses operating across multiple states to ensure correct tax payment and credit availment.

Definition of Inter-State Services

Inter-state services refer to the supply of services where the location of the supplier and the place of supply are in different states or union territories. According to Section 7 of the IGST Act, 2017, such a supply qualifies as inter-state and is taxable under IGST. This definition is critical because it overrides the older service tax principles that were more ambiguous about cross-jurisdictional services.

Determining the Place of Supply

The place of supply is the key factor in identifying whether a transaction is inter-state. For B2B transactions, the place of supply is generally the location of the recipient. For B2C services, it may vary depending on the nature of the service—whether it’s performed at a specific location, remotely, or electronically. Rules for determining place of supply are detailed in Section 12 and 13 of the IGST Act.

IGST as Applicable Tax

For inter-state services, IGST is levied and collected by the Central Government. This tax replaces the combination of Central and State levies seen under the previous Service Tax and VAT structure. The applicable IGST rate depends on the classification of service under the HSN (Harmonised System of Nomenclature) codes. The tax is collected from the recipient in most B2B transactions.

Registration Requirements

Any service provider making inter-state supplies is required to register under GST, irrespective of their turnover threshold. Unlike intra-state transactions, where a basic exemption is available, inter-state service providers must obtain GSTIN from the beginning. This rule ensures all inter-state services are brought under the tax net.

Invoicing and Compliance

GST-compliant invoices must be raised for all inter-state services, mentioning IGST as the applicable tax. These invoices should include the GSTIN of both the supplier and recipient and clearly state the place of supply. Monthly returns must be filed through GSTR-1 and GSTR-3B, reflecting inter-state sales and IGST collected.

Input Tax Credit on IGST

One major benefit of IGST on inter-state services is the seamless availability of input tax credit. IGST paid on inter-state purchases or services can be used to offset IGST, CGST, and SGST liabilities in a priority sequence. This feature prevents cascading of taxes and promotes ease of doing business across state borders.

Impact on E-commerce and Online Services

Inter-state service rules significantly impact e-commerce operators and digital service providers. For example, online platforms offering services across states must track user locations accurately and apply IGST accordingly. Even if the service is delivered electronically, the tax liability depends on the place of supply rules defined for digital services.

Reverse Charge Mechanism in Inter-State Services

For certain notified services or import of services, the recipient is liable to pay IGST under the reverse charge mechanism (RCM). In such cases, the recipient must self-invoice and report the tax liability under inter-state transactions. This is particularly relevant for foreign services consumed by Indian businesses.

Cross-Border Services as Inter-State Supplies

Services supplied from or to a location outside India are also considered inter-state supplies. However, such services are often categorized under export or import of services and have different tax implications—exports are zero-rated and imports attract IGST under RCM. Thus, cross-border transactions always qualify as inter-state in classification.

Legal and Procedural Clarity

The IGST Act, along with various circulars and notifications issued by the GST Council, provides detailed guidance on the treatment of inter-state services. Businesses are required to maintain proper records, invoices, and audit trails to ensure compliance and defend their tax positions in case of scrutiny.

Conclusion

The rules for inter-state services under India’s GST regime offer a clear and structured approach for taxation and compliance. The classification depends heavily on the place of supply, and IGST becomes the central levy. With mandatory registration, accurate invoicing, and input tax credit mechanisms, inter-state service providers must adhere to the framework to remain compliant. Understanding and applying these rules is vital for operational efficiency and minimizing tax-related risks across state boundaries.
