The framework of Goods and Services Tax was introduced in 2017 as one of India’s impactful tax reforms. It was meant to bring all the indirect taxes under one system, to make it uniform, and to make the flow of tax credit smooth across the supply chain. However, even with the aim of making tax compliance easier and reducing disputes, many GST-related issues still arise because of complex rules, interpretation problems, and procedural mistakes.
To understand the various types of GST disputes is essential for businesses, tax professionals and policymakers to identify areas of conflict and to adopt preventive measures. This article will provide an in-depth overview of the various categories of GST-related disputes commonly encountered in India.
Different Types of GST Disputes
1. Classification Disputes
One of the most common causes of litigation under GST is the classification of goods and services. GST rates often vary, depending on how a product or service is classified under the Harmonised System of Nomenclature or Service Accounting Code.
Similarly, services such as software development, consultancy, or composite supply often led to confusion regarding correct classification.
Common reasons for classification disputes:
- Ambiguity in the nature or composition of products.
- Overlapping entries in GST rate schedules.
- Lack of clarity in interpreting composite vs. mixed supply.
- Divergent Advance Rulings by different states.
Inaccurate classification may lead to the short payment of tax, interest and penalties, making it important for the taxpayers to exercise due diligence and to seek expert opinions where necessary.
2. Valuation Disputes
Valuation under GST determines the taxable amount on which tax is calculated. Disputes often arise over what constitutes “transaction value” and what should be included or excluded from it.
The GST Valuation Rules under the CGST Rules, 2017, outline the specific inclusions, such as incidental expenses, commission, or subsidies, directly linked to the supply. However, differing interpretations often create complexity and conflict.
Common valuation-related disputes include:
- Inclusion of discounts, subsidies, or reimbursements.
- Valuation in case of related-party transactions.
- Inclusion of notional interest on security deposits.
- Determining value when consideration is partly non-monetary.
3. Input Tax Credit (ITC) Disputes
Disputes relating to the Input Tax Credit (ITC) are among the most contentious under the GST reform. The ITC mechanism is specifically designed to eliminate the cascading effect of taxes, but also strict conditions and frequent changes in rules have made it a major source of litigation.
Common areas of ITC disputes:
- Mismatch between GSTR-2A/2B and GSTR-3B: ITC claims not reflecting in the supplier’s returns often lead to denial of credit.
- Blocked credits under Section 17(5): Certain goods and services (like motor vehicles, food & beverages, etc.) are ineligible for ITC, leading to differing interpretations.
- Time limits for availing ITC: Delays in claiming credit beyond the prescribed time limits often attract disputes.
- Use of ITC for exempt or non-business activities.
Proper reconciliation of returns and maintaining supplier compliance are key to preventing ITC-related disputes.
4. Place of Supply Disputes
Determining the place of supply is vital as it identifies whether a transaction is an intra-state supply (CGST + SGST) or an inter-state supply (IGST). Errors in determining the place of supply can result in wrong tax payments and the denial of credit to the recipient.
Common instances of disputes:
- Services involving cross-border or inter-state elements.
- Supply of goods with installation or delivery at multiple locations.
- Online or digital services are supplied across states.
- Export and import transactions involving intermediary services.
Businesses dealing with multi-state operations must have a clear understanding of place-of-supply provisions under Sections 10–13 of the IGST Act, 2017, to ensure compliance.
5. Time of Supply Disputes
The time of supply determines when tax becomes payable. Incorrect determination may lead to payment delays, interest or penalties.
Frequent causes of disputes include:
- Advance payments received before the supply.
- Continuous supply of goods or services.
- Changes in tax rate between invoice and delivery.
- Reverse charge transactions with delayed invoicing.
Accurate maintenance of invoices, contracts and payment records is essential to establish the correct time of supply.
6. Exemption and Concession Disputes
Several goods and services are exempt from GST or attract concessional GST rates, as notified by the government. However, disputes arise over eligibility, classification, and conditions attached to exemptions.
For example, the supply of educational or healthcare services may be exempt, but disputes occur when services are provided through outsourced or ancillary arrangements. Similarly, manufacturers claiming exemption under specific notifications often face scrutiny over compliance with conditions.
7. Refund and Rebate Disputes
The Refund-related disputes are a major area of the GST litigation, particularly for exporters and businesses with inverted duty structures.
Common refund disputes include:
- Delay or rejection of refund applications due to procedural lapses.
- Refund claims on account of inverted duty are not supported by proper documentation.
- Denial of refund on account of input tax credit mismatch.
- Disputes over refund eligibility in zero-rated supplies (exports and SEZ).
Efficient refund processing and adherence to prescribed formats and timelines under Rule 89 of the CGST Rules are essential to avoid disputes.
8. Compliance and Procedural Disputes
Disputes also arise due to some procedural non-compliance, such as incorrect or inaccurate filing of returns, late payments, or non-issuance of invoices. Various businesses, especially small and medium enterprises, struggle with evolving compliance norms, frequent portal updates, and complex filing requirements…!
Examples of procedural disputes:
- Late filing of GSTR-3B or GSTR-9 leads to penalties.
- Non-registration despite crossing threshold limits.
- Wrongful availment of the composition scheme.
- Omission of outward supplies in returns.
Maintaining proper records, timely filing and using professional assistance can minimize compliance disputes.
Conclusion
While the GST was envisioned as a unified, uniform, and simplified tax regime, its practical implementation has given rise to several types of disputes, ranging from classification and valuation to input tax credit and compliance. As the system evolves, continuous efforts by both taxpayers and authorities are necessary to minimise the ambiguities and promote consistency.
To avoid various disputes, businesses should focus on accurate record-keeping, regular reconciliation, timely compliance and professional consultation. Over time, as judicial precedents develop and technology-driven compliance improves, the frequency and complexity of GST disputes are expected to decline, bringing greater certainty to India’s indirect tax landscape.
