How to File Income Tax Appeal Against Assessment Order in India

An assessment order can result in additions, disallowances, penalties or a substantial income tax demand. If the taxpayer disagrees with the order, the law provides a statutory right of appeal before the appropriate first appellate authority. The appeal must be filed in the prescribed form, within the applicable time limit and with properly drafted facts, grounds and supporting documents.

From 1 April 2026, appeals governed by the Income-tax Act, 2025 are filed under the new appellate framework. Form 99 is the prescribed electronic form for an appeal to the Joint Commissioner of Income-tax (Appeals) or Commissioner of Income-tax (Appeals). Proceedings relating to earlier periods may continue under the Income-tax Act, 1961 under the applicable transition provisions, in which case the familiar Form 35 framework may continue to apply.

This guide explains how to file an income tax appeal against an assessment order in India, including limitation, appeal fees, Form 99, Statement of Facts, Grounds of Appeal, additional evidence, condonation of delay, stay of demand and the powers of the appellate authority.

What Is an Income Tax Appeal Against an Assessment Order?

An Appeal Challenges an Adverse Tax Order

An appeal is the statutory remedy available to a taxpayer who is aggrieved by an appealable order passed by the Income Tax Department. It allows the taxpayer to challenge additions, disallowances, tax computations, penalties or other appealable findings before an independent appellate authority within the Department.

The Appeal Is Different From a Rectification Application

Rectification is generally used for a mistake apparent from the record. An appeal is appropriate where the taxpayer disputes the legal or factual conclusions in the assessment order and requires adjudication on the merits.

The Appeal Does Not Automatically Stay Recovery

Filing an appeal does not by itself suspend recovery of the disputed tax demand. Where recovery is a concern, a separate stay application should be considered. See Stay of Income Tax Demand After Assessment Order in India.

When Can an Assessment Order Be Appealed?

Only Appealable Orders Can Be Challenged Through the Statutory Appeal Route

The Income-tax Act specifies the categories of orders against which an appeal may be filed. Under the Income-tax Act, 2025, sections 356 and 357 contain the first-appellate framework for appealable orders before the Joint Commissioner (Appeals) or Commissioner (Appeals), as applicable.

Assessment and Penalty Orders Are Common Appeal Matters

Typical disputes include additions to returned income, disallowance of expenditure or deductions, unexplained income findings, reassessment additions, best judgment assessment and penalty orders. The exact appeal provision should be checked from the order itself.

Review the Order Before Choosing the Remedy

Before filing, identify whether the issue requires appeal, rectification, revision or another remedy. Filing the wrong proceeding can cause delay and may create limitation problems.

Who Hears the First Income Tax Appeal?

Appeals May Lie to JCIT(A) or CIT(A)

Form 99 is designed for appeals to the Joint Commissioner of Income-tax (Appeals) or the Commissioner of Income-tax (Appeals). The appropriate appellate authority depends on the statutory allocation and the nature of the order.

The Appellate Authority Is Different From the Assessing Officer

The officer who passed the assessment order does not decide the first appeal against that order. The appellate authority independently considers the grounds raised, the assessment record, submissions and admissible evidence.

The Appellate Hierarchy Continues Beyond the First Appeal

The current appellate structure broadly continues as Assessing Officer → JCIT(A)/CIT(A) → Income Tax Appellate Tribunal → High Court → Supreme Court, subject to the statutory conditions for each level.

What Is the Time Limit for Filing an Income Tax Appeal?

The Normal Time Limit Is 30 Days

Under section 358 of the Income-tax Act, 2025, an appeal relating to assessment or penalty is generally required to be presented within 30 days from the date of service of the notice of demand relating to that assessment or penalty.

Calculate Limitation From the Correct Starting Date

The starting point is important. For assessment or penalty appeals, the relevant trigger is generally service of the notice of demand. For other appealable orders, the Act may prescribe the date on which the relevant order or intimation is served.

Do Not Wait Until the Last Day

Appeal preparation may require obtaining the assessment order, demand notice, return, submissions filed during assessment, supporting evidence, challans and other records. Starting early reduces the risk of an incomplete filing or a condonation request.

What Is Form 99 Under the Income-tax Rules, 2026?

Form 99 Is the Current First-Appeal Form Under the New Act

For appeals governed by the Income-tax Act, 2025, Form 99 is the prescribed electronic form for filing an appeal before the Joint Commissioner (Appeals) or Commissioner (Appeals).

Form 99 Corresponds to the Earlier Form 35

The Income Tax Department’s official Form 99 FAQs identify Form 99 under section 358 and rule 167 of the Income-tax Rules, 2026 as corresponding to Form 35 under section 249 and rule 45 of the earlier framework.

Form 99 Requires Detailed Appeal Information

The form requires information about the appellant, the order under challenge, tax year or block period, demand, appeal fee, Statement of Facts, Grounds of Appeal, relevant sections and supporting documents. Additional evidence, where applicable, must be disclosed in accordance with the prescribed rules.

Official filing guidance is available in the Income Tax Department’s Form 99 FAQs.

What Is the Appeal Fee for Filing Form 99?

Appeal Fee Depends on the Assessed Total Income

Total Income Computed by Assessing Officer	Appeal Fee
₹1,00,000 or less	₹250
More than ₹1,00,000 but not more than ₹2,00,000	₹500
More than ₹2,00,000	₹1,000
Other appeal matters not covered above	₹250

Keep the Appeal Fee Challan Details Ready

Form 99 requires details of the appeal fee paid. Verify the amount, payment particulars and challan before final submission so that the appeal is not delayed by an avoidable procedural defect.

How to Draft the Statement of Facts?

State the Facts Chronologically and Objectively

The Statement of Facts should explain the return filed, notices received, proceedings conducted, documents submitted, additions proposed and conclusions reached by the Assessing Officer. It should allow the appellate authority to understand the dispute without reconstructing the entire assessment record.

Distinguish Facts From Legal Arguments

Facts should describe what happened. Legal propositions and challenges to the assessment should primarily be expressed through the Grounds of Appeal and written submissions. Mixing lengthy arguments into the factual narrative can reduce clarity.

Ensure the Statement Matches the Assessment Record

Dates, amounts, notices, submissions and annexures should be reconciled with the assessment order and portal record. Avoid statements that conflict with earlier submissions unless the difference is specifically explained.

How to Draft Effective Grounds of Appeal?

Each Ground Should Identify a Specific Grievance

A good ground should state exactly what is being challenged, such as an addition, disallowance, jurisdictional defect, denial of opportunity, incorrect computation or penalty. Avoid vague grounds that merely state that the order is “bad in law” without identifying the issue.

Keep Grounds Concise and Independent

The Income Tax Department’s Form 99 guidance states that each Ground of Appeal should not exceed 100 words. Separate material issues into distinct grounds so that each question can be adjudicated clearly.

Include Jurisdictional and Procedural Grounds Where Relevant

If the assessment suffers from a limitation issue, invalid notice, lack of jurisdiction, denial of natural justice or another procedural defect, those grounds should be separately considered in addition to challenging the additions on merits.

What Documents Are Required for an Income Tax Appeal?

Assessment Order and Notice of Demand

Keep the complete assessment or penalty order and the corresponding notice of demand. These identify the order under challenge, date of service, section, tax year and amount disputed.

Return, Computation and Assessment Submissions

Maintain the filed return, computation of income, financial statements where applicable, notices issued during assessment and all replies and supporting evidence submitted to the Assessing Officer.

Appeal-Specific Documents

Prepare the appeal fee challan, Statement of Facts, Grounds of Appeal, supporting records, authority documents where a representative is involved and a clear index of annexures. Where additional evidence is proposed, comply separately with the rules governing its admission.

Can Additional Evidence Be Filed in an Income Tax Appeal?

Additional Evidence Is Not Automatically Admissible

The first appeal is not intended to become an unrestricted opportunity to submit material that could have been produced during assessment. Additional evidence is governed by prescribed conditions.

Rule 192 Governs Additional Evidence Under the New Rules

Rule 192 of the Income-tax Rules, 2026 allows additional evidence in specified circumstances, including where the Assessing Officer refused evidence that ought to have been admitted or where sufficient cause prevented the taxpayer from producing relevant evidence earlier.

Explain Why the Evidence Could Not Be Produced Earlier

If additional evidence is necessary, prepare a clear application identifying each document, its relevance to the grounds of appeal and the reason it was not produced before the Assessing Officer. Form 99 also requires disclosure and linking of additional documents to the relevant grounds.

What if the Income Tax Appeal Is Filed Late?

Delay Does Not Automatically End the Right of Appeal

Section 358 permits the appellate authority to admit an appeal after expiry of the normal limitation period where sufficient cause for the delay is established, subject to the statutory framework.

A Condonation Request Should Explain the Entire Delay

The application should provide a clear chronology, explain why the appeal could not be filed within time and attach supporting evidence wherever possible. General statements such as “the delay was inadvertent” are less persuasive than a factual explanation.

File Promptly Once the Cause of Delay Ends

Where the taxpayer discovers a missed limitation period, the appeal and condonation request should be prepared without further avoidable delay. Continuing inaction after discovering the default can weaken the explanation.

How Are Income Tax Appeals Conducted Electronically?

Appeal Filing Is Electronic

Form 99 is an electronic appeal form. Notices, submissions, adjournment requests and other appellate communications may also be handled through the Income Tax Department’s electronic systems, depending on the applicable proceeding.

Monitor the Portal After Filing

Filing the appeal is only the first step. The taxpayer should monitor the registered email address and e-Filing account for hearing notices, document requests, remand-related communications or other directions.

Written Submissions Should Be Issue-Wise

For each ground, written submissions should ordinarily contain the relevant facts, assessment finding, taxpayer’s response, documentary support and legal proposition. A well-indexed and cross-referenced submission makes electronic adjudication easier.

Should a Stay of Demand Be Filed Along With the Appeal?

An Appeal Does Not Automatically Stop Recovery

A pending appeal does not by itself place the demand in abeyance. If the assessment creates a disputed demand and immediate recovery is a concern, the taxpayer should separately consider a stay application.

Appeal and Stay Grounds Should Be Consistent

The stay application should accurately reflect the disputed additions, tax demand and main merits raised in the appeal. Payments already made or refunds already adjusted should also be reconciled.

Do Not Delay the Stay Application Where Recovery Risk Exists

Where the demand is significant, stay planning should begin immediately after the assessment order is reviewed. Detailed guidance is available in Stay of Income Tax Demand After Assessment Order in India.

What Powers Does the Appellate Authority Have?

The Assessment Can Be Confirmed, Reduced, Enhanced or Annulled

Section 360 of the Income-tax Act, 2025 empowers the Joint Commissioner (Appeals) or Commissioner (Appeals), as applicable, to confirm, reduce, enhance or annul an assessment. In specified best judgment assessment cases, the Commissioner (Appeals) may also have the statutory power to set aside the assessment and refer the matter back for fresh assessment.

Enhancement Requires an Opportunity to Respond

The appellate authority cannot enhance the assessment or penalty or reduce a refund without giving the appellant a reasonable opportunity to show cause against the proposed adverse action.

The Appellate Authority Can Examine Matters Arising From the Proceedings

Section 360 also permits consideration of matters arising out of the proceedings in which the appealed order was passed even if the taxpayer did not specifically raise that matter in the original grounds. This makes careful preparation of the appellate record important.

What Happens After the First Appellate Order?

The Appeal May Be Allowed, Partly Allowed or Dismissed

The appellate order may delete additions, grant partial relief, confirm the assessment, enhance it after due opportunity or otherwise dispose of the appeal in accordance with the statutory powers.

Further Appeal May Lie to the ITAT

If the taxpayer or Department remains aggrieved by an appealable first-appellate order, a further appeal may lie before the Income Tax Appellate Tribunal subject to the applicable statutory provisions, limitation and filing requirements.

Give Effect to the Appellate Order and Reconcile the Demand

After relief is granted, verify that the Department correctly gives effect to the appellate order and updates the demand or refund. If the portal continues to show an incorrect outstanding demand, appropriate follow-up or rectification may be required.
