Notices, Show Cause Replies & Summons
We assist clients in drafting accurate, well-reasoned responses to income tax and GST notices, show cause notices, and summons issued by tax authorities. Our team ensures that every submission is timely, fact-based, and legally sound to prevent escalation of issues and avoid penalties or prosecution.
Representation before Tax Authorities
Our team represents clients during assessments, audits, and investigations before Income Tax Officers, GST Officers, and other relevant authorities. We work diligently to present accurate facts, legal positions, and supporting documentation to protect client interests at the primary level of proceedings.
Appeals before Appellate Authorities
We handle appeals before Commissioner (Appeals), Income Tax Appellate Tribunal (ITAT), and GST Appellate Authorities with detailed documentation, strategic arguments, and expert representation. Our approach is focused on building a strong case backed by legal precedents and tax law interpretations.
TDS Litigation & Recovery Proceedings
TDS defaults or mismatches can result in penalties and recovery actions. We help clients resolve disputes related to TDS deductions, non-payments, and mismatches by representing them before tax officers and appellate forums, ensuring that demands are reduced or nullified where legally feasible.
International Tax & Transfer Pricing Disputes
Cross-border transactions often lead to disputes under international tax laws and DTAAs. We advise and represent clients in complex matters such as transfer pricing adjustments, including representation before Transfer Pricing Officers and Dispute Resolution Panels.
Representation before High Courts
In cases requiring judicial intervention, we represent clients before High Courts in writ petitions, appellate tax matters, and constitutional challenges. Our legal team is well-versed in drafting petitions, handling complex arguments, and securing interim reliefs or final judgments in high-stakes tax matters.
