GST & Indirect Tax Advisory & Litigation Services in India

Simplifying GST Compliance, Advisory and Litigation for Businesses

India’s Goods and Services Tax (GST) has transformed the country’s indirect tax regime by replacing multiple indirect taxes with a unified taxation system. While GST has simplified taxation in many respects, it has also introduced a complex compliance framework involving registration, classification of goods and services, input tax credit, e-invoicing, e-way bills, cross-border taxation, assessments, departmental audits and litigation.

Businesses today face increasing scrutiny from GST authorities due to extensive use of technology, data analytics and artificial intelligence. Differences between GST returns, e-invoices, e-way bills, customs records, TDS/TCS data and financial statements are automatically identified, often leading to notices, investigations and disputes. Consequently, businesses require not only compliance support but also strategic advisory and experienced representation before tax authorities.

At EzyBiz India Consulting LLP, we provide comprehensive GST and indirect tax advisory services to domestic businesses, multinational corporations, foreign companies operating in India, manufacturers, traders, service providers, exporters, importers, e-commerce businesses and start-ups. Our professionals assist clients throughout the business lifecycle—from GST registration and tax planning to departmental audits, investigations, adjudication proceedings, appeals before the GST Appellate Tribunal (GSTAT), High Courts and the Supreme Court.

Whether you are establishing a new business in India, expanding operations, restructuring your supply chain or defending a GST dispute, our objective is to minimise tax risks, ensure regulatory compliance and protect your business interests.

Monthly, quarterly and annual GST return filing
GSTR-1, GSTR-3B and other applicable returns

Return reconciliation

GST Departmental Audits and Special Audits

With the increasing use of data analytics, artificial intelligence and integrated information systems, GST authorities are conducting more detailed departmental audits to verify tax compliance. Businesses are expected to maintain accurate records and reconcile GST returns with financial statements, e-invoices, e-way bills and other statutory records.

A departmental audit can result in demands for tax, interest and penalties if discrepancies are identified. Timely professional assistance is therefore essential to safeguard business interests.

Our professionals assist clients in:

Assistance during Special Audits under Section 66
Review of books of accounts and supporting records
Preparation of reconciliations and documentary evidence
Representation before GST audit officers
Reply to audit observations and audit reports
Negotiation and resolution of disputed issues
Post-audit advisory and corrective compliance measures

Our objective is to minimise tax exposure while ensuring that the audit is concluded efficiently and in accordance with applicable law.

GST Assessments and Scrutiny Proceedings

GST authorities have the power to scrutinise returns, verify tax payments and assess the correctness of declarations made by taxpayers. Such proceedings may arise due to mismatches in GST returns, discrepancies identified through data analytics or information received from other government departments.

Our team represents businesses throughout assessment and scrutiny proceedings, including:

Scrutiny of GST returns
Reply to notices issued by GST authorities
Reconciliation of GSTR-1, GSTR-3B and books of accounts
Classification disputes

Preparation of written submissions and supporting documentation

Our objective is to resolve issues at the assessment stage itself and avoid unnecessary litigation.

GST Search, Inspection and Seizure

GST authorities have extensive powers to conduct inspections, searches and seizures where they believe that tax evasion or non-compliance has occurred. Such proceedings can significantly disrupt business operations and require immediate professional assistance.

We assist businesses in:

Advisory during search and inspection proceedings
Representation before GST officers
Review of legal validity of search authorisations
Assistance during recording of statements
Documentation and evidence management

The Directorate General of GST Intelligence (DGGI) investigates cases involving alleged tax evasion, fake invoicing, wrongful Input Tax Credit claims and other serious GST violations. Such investigations often involve extensive examination of business records and interactions with company management.

Review of investigation notices and summons
Preparation of legal and factual responses
Representation before DGGI officers
Assistance during recording of statements
Review of documentary evidence
Advisory on voluntary tax payments, where appropriate

Our focus is on protecting the client’s legal rights while facilitating an efficient resolution of the investigation.

Show Cause Notices and Adjudication Proceedings

Many GST disputes begin with the issuance of a Show Cause Notice (SCN). The outcome of adjudication proceedings often determines whether a dispute can be resolved at the departmental level or proceeds to appellate forums.

An effective response requires a thorough understanding of GST law, judicial precedents and departmental practices.

Our services include:

Detailed review of Show Cause Notices
Legal analysis of allegations
Preparation of comprehensive written replies
Compilation of supporting evidence
Representation during personal hearings

Review of adjudication orders

GST law provides for refunds in various situations, including exports, inverted duty structures, excess tax payments and accumulated Input Tax Credit. However, obtaining refunds often involves detailed documentation and interaction with tax authorities.

We assist clients with:

Export refunds
Refund of accumulated Input Tax Credit
Refund under inverted duty structure
Refund of excess tax paid
Refund arising from appellate orders
Preparation and filing of refund applications
Documentation and reconciliations
Representation before refund authorities

Advance Rulings enable taxpayers to obtain certainty on the GST implications of proposed or existing transactions. They are particularly useful where the interpretation of GST provisions is unclear.

Our professionals advise clients on:

Eligibility for Advance Ruling applications
Classification of goods and services
Determination of applicable GST rates
Place of supply issues
Eligibility of Input Tax Credit
Applicability of exemptions
Preparation and filing of Advance Ruling applications
Representation before the Authority for Advance Ruling (AAR) and Appellate Authority for Advance Ruling (AAAR)

Obtaining an Advance Ruling can significantly reduce future tax disputes and provide greater certainty for business planning.

Anti-Profiteering Advisory

The anti-profiteering provisions under GST require businesses to pass on the benefits of tax rate reductions or increased Input Tax Credit to consumers by way of commensurate reductions in prices. Non-compliance may result in investigations and significant financial consequences.

We assist businesses in:

Evaluation of anti-profiteering implications
Pricing policy review
Documentation of pricing decisions
Representation before appropriate authorities
Preparation of legal submissions
Assistance during investigations and proceedings

Our advisory helps businesses demonstrate compliance while mitigating regulatory risks.

GST Advisory for E-Commerce Businesses

GST registration requirements
TCS compliance
Place of supply rules
Marketplace transactions
Cross-border digital services

Jurisdictional GST Authorities
Audit Officers
Investigation Wings
DGGI Authorities
Refund Authorities

Appellate Authorities

We prepare detailed legal submissions, present factual and legal arguments, attend personal hearings and work towards achieving practical and commercially viable resolutions for our clients.

GST Appeals and Appellate Advisory

Despite best compliance efforts, disputes with GST authorities may arise due to differing interpretations of law, classification issues, valuation disputes, denial of Input Tax Credit, refund rejections or procedural non-compliance. An effective appellate strategy is critical to safeguarding the interests of taxpayers.

Our professionals provide end-to-end assistance in GST appellate proceedings, including:

Review of assessment and adjudication orders
Evaluation of legal merits and litigation strategy
Preparation and filing of appeals
Drafting of Statements of Facts and Grounds of Appeal
Preparation of written submissions

The operationalisation of the Goods and Services Tax Appellate Tribunal (GSTAT) marks a significant milestone in India’s indirect tax dispute resolution framework. The Tribunal provides taxpayers with a specialised appellate forum for challenging orders passed by the First Appellate Authority.

Given the technical and legal complexities involved, businesses require experienced professionals who can effectively present factual and legal arguments before the Tribunal.

Frequently Asked Questions (FAQs)

Who is required to obtain GST registration in India?

GST registration is mandatory for businesses exceeding the prescribed turnover threshold and for certain specified categories of taxpayers, such as e-commerce operators, non-resident taxable persons and businesses engaged in inter-State taxable supplies, subject to the provisions of the GST law.

Can a business claim Input Tax Credit on all purchases?

No. Input Tax Credit is available only where the statutory conditions prescribed under the GST law are satisfied. Certain credits are specifically restricted or blocked, and businesses must ensure proper documentation and vendor compliance before claiming ITC.

What happens if a GST notice is ignored?

Failure to respond to a GST notice may result in ex parte orders, tax demands, interest, penalties and recovery proceedings. It is advisable to seek professional advice immediately upon receiving any communication from the GST authorities.

What is the GST Appellate Tribunal (GSTAT)?

The GST Appellate Tribunal is the specialised appellate authority established to hear appeals against orders passed by the First Appellate Authority under the GST laws. It provides taxpayers with an independent forum for resolving GST disputes before approaching the High Courts.

Can foreign companies be required to comply with GST in India?

Yes. Depending on the nature of their business activities, foreign companies may be required to obtain GST registration, discharge tax liabilities, comply with return filing requirements or appoint authorised representatives in India.
