Income tax notices, appeals and GST disputes in Kolkata

Tax problems in Kolkata affect salaried people, traders, professionals and companies alike. Individuals receive notices about mismatches between their returns and the information in their annual statements, high-value cash deposits, or capital gains on property sales. Traders in the city's wholesale markets face GST notices over input tax credit claimed from suppliers who did not pay tax, e-way bill lapses and differences between returns. Companies face reassessment proceedings, transfer pricing questions and penalties. Many of these notices arrive by email and are easy to miss.

For income tax, the Income-tax Act, 2025 applies from 1 April 2026, while proceedings for earlier years remain under the Income-tax Act, 1961. Most assessments and first appeals are now handled through faceless procedures, with replies filed online. GST disputes are governed by the Central Goods and Services Tax Act, 2017 and the West Bengal Goods and Services Tax Act, 2017, with notices issued either by the central GST authorities or by the state tax department.

The single most important rule is to reply to every notice within the time it gives. If no reply is filed, the officer may pass an ex-parte assessment or demand order, which is much harder to undo. Where more time is genuinely needed, an adjournment can be requested in writing before the deadline. A good reply addresses each point raised, attaches supporting documents, and keeps to the facts. Where a demand is raised, a stay of recovery can be sought while an appeal is pending, often on deposit of a part of the disputed amount.

Main law: Income-tax law (the Income-tax Act, 2025 applies from 1 April 2026; earlier years remain under the Income-tax Act, 1961); Central and State GST Acts, 2017.

Where these matters are heard in Kolkata

For income tax, an appeal against an assessment order generally lies first to the Commissioner of Income Tax (Appeals), now largely through the faceless appeals system. A second appeal lies to the ITAT Kolkata Bench, which hears appeals from taxpayers in West Bengal and nearby regions, and its findings on facts are final. On substantial questions of law, an appeal lies to the Calcutta High Court and then to the Supreme Court. Writ petitions before the Calcutta High Court are also filed in cases of jurisdictional errors or breach of natural justice.

For GST, an appeal against an adjudication order lies to the Appellate Authority, and from there to the GST Appellate Tribunal bench that covers West Bengal; your advocate will confirm the current bench. Questions of law can be taken to the Calcutta High Court. Each stage has a strict period for filing and requires a pre-deposit of a percentage of the disputed tax, so timelines must be watched closely.

How a tax matter usually moves in Kolkata

Read the notice carefully
Identify the section under which the notice is issued, the assessment year or tax period, the deadline and what is being asked. Check that it was issued by the officer with jurisdiction. Note the deadline in your calendar on the day the notice arrives.
Collect records and reconcile
Gather returns, annual information statements, bank statements, invoices and books of account. Reconcile the figures with what the department has flagged to see where the difference arises. A clear reconciliation often answers the department's query on its own.
Draft and file the reply
The reply is filed online on the income tax or GST portal with supporting documents. If more time is needed, an adjournment request is filed before the due date. Keep the acknowledgement of every submission.
Personal hearing, if granted
In many cases the taxpayer can request a hearing through video conference. Your advocate or chartered accountant explains the position and answers the officer's questions. Prepare a short written note of submissions to file along with the hearing.
Order and stay of demand
If an adverse order is passed, an application for stay of demand is made to the assessing officer or a higher authority. Paying the prescribed portion of the demand often secures a stay during appeal.
Appeal within the time limit
File the appeal before the Commissioner (Appeals) or the GST Appellate Authority within the period given in the order. Further appeals lie to the ITAT Kolkata Bench or the GST Appellate Tribunal and then the Calcutta High Court on questions of law. Missing the deadline may require an application for condonation of delay, which is not automatic.

Documents to keep ready

Mistakes to avoid

Keeping no reconciliation between books, returns and bank statements.

Kolkata: local points to know

The ITAT Kolkata Bench hears second appeals from taxpayers in Kolkata and the wider region, and hearings are generally in English with documents filed in a paper book.
GST notices to Kolkata businesses may come either from the central GST authorities or from the West Bengal state tax department, so check which authority issued yours before replying.
Traders in the city's large wholesale markets often face input tax credit disputes linked to suppliers' defaults, and records of payment to and goods received from those suppliers are central to the defence.
Old business records, especially of family firms, may be kept in Bengali or Hindi, and translations may be needed when the matter reaches the Tribunal or the Calcutta High Court.
Writ petitions against tax notices issued without jurisdiction or in breach of natural justice are heard by the Calcutta High Court, which can stay proceedings in suitable cases.

Choosing and working with an advocate

Tax disputes often involve both accounting and law, so it helps to work with an advocate who handles income tax or GST matters regularly and coordinates with your chartered accountant. Ask whether the advocate appears before the ITAT Kolkata Bench, GST authorities and the Calcutta High Court, and verify the enrolment number with the Bar Council of West Bengal.

Agree the fee and scope in writing, for example whether it covers only the reply or also the appeal, stay application and hearings, and get receipts for every payment. Fees depend on the advocate and the matter.

Questions people ask about tax matters in Kolkata

I received an income tax notice in Kolkata. What should I do first?

Read the notice to see the section, the year and the deadline, and log in to the income tax portal to view it. Collect the documents it refers to and reply before the due date, or request an adjournment in writing if you need time. Do not ignore it. Check also whether the same issue has arisen in other years.

Which law applies to my notice, the 1961 Act or the 2025 Act?

The Income-tax Act, 2025 applies from 1 April 2026, while proceedings relating to earlier years continue under the Income-tax Act, 1961. The notice itself will state the provision, and your advocate will confirm the applicable law.

Where is the Income Tax Appellate Tribunal for Kolkata?

The ITAT Kolkata Bench sits in the city and hears second appeals against orders of the Commissioner (Appeals). It is the final fact-finding authority, and further appeals lie to the Calcutta High Court only on substantial questions of law. Appeals to the Tribunal must be filed within the time set by law, with the prescribed fee and a paper book of documents.

Can recovery of a tax demand be stopped during appeal?

You can apply for a stay of demand while the appeal is pending. Authorities often grant a stay if a part of the disputed demand is paid, and the Tribunal or the High Court can also grant a stay in suitable cases.

My GST input credit was denied because of a supplier's default. What can I do?

Reply with proof that you received the goods or services, paid the supplier including tax, and hold valid invoices. Courts have taken the view in several cases that a genuine buyer should not suffer automatically for the supplier's default, but the outcome depends on the facts and documents. Keep transport records, payment proofs and supplier correspondence ready.

Is pre-deposit required for a GST appeal?

Yes. A GST appeal requires a pre-deposit of a percentage of the disputed tax, as specified in the law, at each appellate stage. The admitted tax, interest and penalty must also be paid in full. Your advocate will calculate the exact pre-deposit for your appeal.
