GST Litigation & Indirect Tax Dispute Advisory

Dispute-specific support on GST demands, classification, input-credit issues and enforcement allegations, distinct from the policy-representation practice.

Advisory coverage

How TLGS can support you

  • Demand notices, audit findings and classification disputes
  • Input tax credit mismatches and alleged wrongful-credit claims
  • DGGI, anti-evasion and investigation-response documentation
  • Invoice, supply-chain and tax-return reconciliation
  • Adjudication, appellate and court-stage preparation with appropriate professionals

Diagnosing the GST dispute

GST disputes can arise from classification, credit eligibility, return mismatches, valuation and allegations concerning the underlying supply chain. TLGS first isolates the statutory question, the factual record and the basis of the disputed demand.

The source addresses demand notices, audit and enforcement issues, input-credit disagreements and related proceedings. This service is distinct from GST policy clarification and sector-wide representations.

  • Demand and show-cause notice analysis
  • Classification and indirect-tax disputes
  • Input-credit mismatch and fraud allegations
  • Investigation and audit-response preparation

Structured litigation preparation

TLGS prepares legal and factual material for adjudication, appeal and appropriate court proceedings with relevant professionals. The focus is the specific order, the available remedy and the evidence required to support the client’s position.

Research notes, reply-support documents, grounds, paper books and hearing briefs are assembled around the contested issues. The analysis is kept consistent across related tax and enforcement proceedings.

  • Issue-specific reply preparation
  • Statutory and precedent research
  • Appellate and court-support documentation
  • Counsel conference and hearing notes

Input-credit and transaction reconstruction

The synopsis emphasises reconstruction of invoices, supplies, bank transactions, returns and related business records. TLGS connects these documents to test the factual basis of disputed credit and alleged irregularities.

Supply-chain explanations are supported by the available evidence. Material inconsistencies are identified and documented, including differences between records used in tax, accounting or enforcement proceedings.

  • Invoice and return reconciliation
  • Supply-chain and payment-trail mapping
  • Input-credit evidence analysis
  • Identification of documentary contradictions

Tax-risk and business-impact management

A significant GST dispute may influence cash flow, vendor relationships and continuing compliance. TLGS helps management assess those implications alongside the legal strategy.

The engagement supports a coherent response, disciplined documentation and clearer choices; it does not guarantee that a demand will be withdrawn or an appeal allowed. For wider interpretive issues affecting a business model or sector, the separate policy practice provides technical position notes and representations.

Section 9(5): digital facilitation or economic intermediation?

Why the proposed assessment focuses on actual platform functions, not a business label—and why passenger mobility must be analysed on its own facts.
