Mumbai has a heavy concentration of income tax, GST and customs work because so many companies, traders, importers and high-income earners are based here. This page explains how tax disputes move through the offices and tribunals in Mumbai and helps you book a free consultation with an enrolled advocate.
Income tax appeals from Mumbai go first to the Commissioner of Income-tax (Appeals) and then to the Mumbai Benches of the ITAT. Tax Lawyers in Mumbai advise on the law, draft the papers and appear for you. Booking a first consultation with an enrolled advocate through Mara Vakil is free.
Tax matters in Mumbai come from a wide mix of people. Salaried employees and professionals receive notices about mismatches between their return and the annual information statement, or about high-value transactions such as property purchases and share trading. Traders in wholesale markets face GST notices about input tax credit taken from suppliers who later turned out to be non-existent. Importers at the Mumbai and Nhava Sheva ports deal with customs valuation and classification disputes. Companies headquartered in the city handle transfer pricing adjustments and international tax questions, and start-ups face questions on share premium and valuation. Non-resident Indians selling a flat in Mumbai often need help with tax deducted at source, capital gains and lower deduction certificates. Search and survey actions and reopening of old assessments also bring many people to an advocate.
Direct tax is governed by the Income-tax Act, 2025, which came into force on 1 April 2026, while assessments, reassessments and appeals for earlier years continue largely under the Income-tax Act, 1961, so the year involved is checked first. Most assessments are now done in faceless mode, with notices issued and replies filed online. Indirect tax is governed by the Central Goods and Services Tax Act, 2017 and the Maharashtra Goods and Services Tax Act, 2017, together with the Integrated GST Act for inter-state supplies. Customs duties fall under the Customs Act, 1962 and the Customs Tariff Act, 1975. Prosecution provisions exist under each law, and serious cases can also involve the Prevention of Money Laundering Act, 2002 or the Black Money Act, 2015, which call for careful handling from the start.
Income tax appeals from an assessment order first go to the Commissioner of Income Tax (Appeals), largely through the faceless appeal system, and then to the Mumbai Benches of the Income Tax Appellate Tribunal, which sit in the city and hear a very large share of the country's tax appeals. Companies with transfer pricing adjustments may instead go to the Dispute Resolution Panel before the final order. The principal income tax offices in the city are at Aayakar Bhavan. GST matters under the state law are handled by the Maharashtra GST Department, headquartered at GST Bhavan, Mazgaon, while central GST and customs commissionerates have their own offices in the city.
GST appeals go first to the appellate authority and then to the GST Appellate Tribunal, which has state benches. Customs and older service tax and excise appeals go to the Mumbai bench of CESTAT. Questions of law from the ITAT and CESTAT, and writ petitions against notices, searches or orders passed without hearing, are filed in the Bombay High Court, which hears a large volume of tax writs. Prosecution complaints under tax laws are heard by designated Magistrate courts in the city, and appeals or revisions from them go to the Sessions Court and the High Court. Appeals from the Bombay High Court in tax matters lie to the Supreme Court.
Replying to income tax and GST notices on time, with documents, and attending faceless or personal hearings where needed. Many disputes end at this stage when the officer accepts a well-documented explanation.
Filing appeals before the Commissioner (Appeals), the Mumbai ITAT, the GST appellate authority or CESTAT, and seeking stay of demand. A stay of demand prevents bank attachment while the appeal is decided.
Challenging reopening, searches or orders without hearing in the Bombay High Court, and defending prosecution complaints. Prosecution can sometimes be resolved through compounding, where the law allows it.
Tax disputes turn on numbers as well as law, so look for an advocate who works closely with your chartered accountant and who regularly appears before the forum your matter is in, whether the Mumbai ITAT, CESTAT, the GST authorities or the Bombay High Court. Ask for the advocate's enrolment number and verify it with the Bar Council of Maharashtra and Goa. Share the full notice history and all earlier replies, because a statement made in one year can affect another. Agree on who files on the portal and who tracks deadlines.
Agree in writing what the fee covers, such as one reply, the first appeal, or the tribunal stage, and keep the pre-deposit and tax payments separate from the fee. Fees depend on the advocate and the matter. Ask for receipts. Individuals who cannot afford representation can ask about free legal aid through the Mumbai City and Mumbai Suburban District Legal Services Authorities or the NALSA helpline 15100.

The Income-tax Act, 2025 came into force on 1 April 2026, but proceedings for years before that continue largely under the Income-tax Act, 1961. Your advocate will check the year, the type of notice and the time limits that apply. Old year notices can sometimes be challenged if they were issued beyond the period allowed. Keep the notice and all replies in one file.
The first appeal goes to the Commissioner of Income Tax (Appeals), mostly through faceless proceedings. The second appeal goes to the Mumbai Benches of the Income Tax Appellate Tribunal. Questions of law can then go to the Bombay High Court. Strict time limits apply at every stage. Always check the time limit before filing.
You can reply with proof that you received the goods or services, paid the supplier through banking channels and hold valid invoices. The outcome depends on the facts and the law applied. If an adverse order is passed, you can appeal to the appellate authority and then to the GST Appellate Tribunal. Keep proof of payment to suppliers in one place.
The buyer must deduct tax at source on the sale price at rates that apply to non-residents, which can be high. You can apply for a lower deduction certificate if your actual capital gain is smaller. You will also need to file a return in India and may be able to claim exemptions by reinvesting. Keep the sale and purchase deeds ready.
Yes, you can apply for stay of demand. For income tax, the officer or higher authority considers stay, often after payment of a part of the demand. For GST and customs, the law requires a pre-deposit when filing the appeal. If stay is wrongly refused, a writ petition can be filed in the Bombay High Court. Ask your advocate to track the hearing dates on the portal.
Cooperate, but read every statement before signing it and ask for a copy. Keep a note of what was seized. Speak to an advocate and chartered accountant quickly, because statements recorded during a search are used later in assessment, and incorrect statements should be addressed early with proper explanation. Do not destroy any records after the search.
No. Describing your matter and booking a first consultation with an enrolled advocate is free. Any fee for further work is agreed directly between you and the advocate.
