How to File an Income Tax Appeal Against Assessment Order in India

If the Income Tax Department passes an assessment order making additions, disallowing expenses or deductions, or raising an additional tax demand, the taxpayer may have the right to challenge that order by filing an income tax appeal before the appropriate appellate authority.

An income tax appeal against an assessment order must be filed within the applicable statutory time limit, using the prescribed form and supported by a clear Statement of Facts, properly drafted Grounds of Appeal and relevant documents.

From 1 April 2026, the Income-tax Act, 2025 introduced the new appellate framework and Form 99. However, appeals relating to earlier assessment years may continue under the Income-tax Act, 1961 and Form 35, subject to the applicable transitional provisions.

This guide explains who can appeal, the applicable law, appeal fees, filing deadlines, Form 35 and Form 99, additional evidence, faceless proceedings, stay of demand and further remedies.

What Is an Income Tax Appeal Against an Assessment Order?

An income tax appeal is a statutory remedy through which an aggrieved taxpayer challenges an appealable order passed by the Income Tax Department.

For example, the Assessing Officer may disallow business expenses, treat certain credits as unexplained income, reject a deduction or make an addition that the taxpayer considers factually or legally incorrect.

Where the order is appealable, the taxpayer may seek relief from the appropriate first appellate authority.

An appeal is different from a rectification application. Rectification generally concerns a mistake apparent from the record, whereas an appeal can involve disputed facts, interpretation of law, additions, disallowances or procedural objections.

Important: Filing an income tax appeal does not automatically stay recovery of the disputed demand. A separate stay application may be necessary.

Which Income Tax Act Applies to Your Appeal in 2026?

The Income-tax Act, 2025 came into force on 1 April 2026, but proceedings relating to earlier tax periods are subject to the applicable repeal, savings and transitional provisions, including section 536.

The form and legal framework should be selected by identifying the law governing the underlying assessment order, not merely the date when the appeal is filed.

For example, an appeal relating to Assessment Year 2026-27, corresponding to Financial Year 2025-26, may continue under the earlier Act and Form 35 framework, even if the appeal is filed after 1 April 2026.

For appeals governed by the new Act, Form 99 is prescribed for an appeal to the Joint Commissioner (Appeals) or Commissioner (Appeals).

The official statutory and procedural guidance is available through the Income Tax Department’s Appeals and Revisions resources.

Which Assessment Orders Can Be Appealed?

The right of appeal is statutory. An appeal may be filed only against an order or intimation for which the governing Act provides an appellate remedy.

Common appeal matters include:

• Scrutiny assessment orders involving additions or disallowances.
• Best judgment assessment orders.
• Reassessment orders involving alleged escaped income.
• Specified processing intimations making adjustments to returned income.
• Specified rectification orders.
• Appealable penalty orders.
• Other orders specifically covered by the applicable appellate provisions.

The exact appealable order and the proper forum should be checked before filing.

For further background on the underlying proceedings, refer to our guides on Income Tax Scrutiny Assessment and Different Types of Income Tax Assessment.

Who Hears the First Income Tax Appeal?

Depending on the applicable statutory provisions and allocation of jurisdiction, a first appeal may lie before the:

• Joint Commissioner of Income-tax (Appeals), commonly referred to as JCIT(A); or
• Commissioner of Income-tax (Appeals), commonly referred to as CIT(A).

The appropriate forum depends on the nature of the order and the governing appellate provisions.

The first appellate authority considers the assessment record, Grounds of Appeal, submissions, admissible evidence and applicable legal provisions before deciding the appeal.

The broader appellate structure generally proceeds from the Assessing Officer to the appropriate first appellate authority, followed by the Income Tax Appellate Tribunal, High Court and Supreme Court, subject to the statutory requirements governing each stage.

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

Under section 249(2) of the Income-tax Act, 1961 and section 358 of the Income-tax Act, 2025, the ordinary time limit for filing a first appeal against an assessment or penalty order is generally 30 days from service of the relevant notice of demand.

For other appealable matters, the limitation period may run from service of the relevant order or intimation, as specified by law.

Illustrative Calculation of Appeal Deadline

Suppose an assessment order and corresponding notice of demand are served on 10 October 2026.

If the statutory appeal period is thirty days from that service date, and no special extension or exclusion applies, the ordinary filing deadline would be 9 November 2026.

This is an illustrative calculation only. The actual limitation period must be calculated using the governing statutory provisions and valid service date, including any applicable rules regarding holidays or exclusions.

What if the Appeal Is Filed Late?

The relevant appellate authority may admit an appeal after the prescribed period if it is satisfied that sufficient cause prevented timely filing.

A taxpayer seeking condonation should normally provide:

• The date of service of the appealable order or notice.
• The reason the appeal could not be filed within time.
• A clear chronology explaining the delay.
• Supporting evidence where available.
• A request for condonation under the applicable provision.

Condonation is discretionary and should not be assumed. Whenever possible, file the appeal within the normal limitation period.

Form 35 vs Form 99: Which Income Tax Appeal Form Should You Use?

Form 35 applies to relevant first appeals under the Income-tax Act, 1961.

Form 99 is the prescribed form for applicable first appeals under the Income-tax Act, 2025 and Rule 167 of the Income-tax Rules, 2026.

Both forms require information about the taxpayer, the order appealed against, the disputed matter, tax and fee details, Statement of Facts, Grounds of Appeal and supporting documents.

However, the forms and applicable legal provisions are not interchangeable. Always select the correct framework for the relevant assessment or tax year.

For official instructions, refer to the Form 35 User Manual and Form 99 User Manual.

What Is the Fee for Filing an Income Tax Appeal?

The filing fee for a standard first appeal depends on the total income computed by the Assessing Officer in the matter under appeal.

The fee is generally linked to assessed total income, not simply the amount of additional tax demanded or the amount disputed.

For an appeal governed by the Income-tax Act, 2025, these fee categories are prescribed under section 358(2).

The prescribed appeal fee should be paid through the applicable e-Pay Tax facility and its challan particulars retained for completing the appeal form.

Professional representation fees, where applicable, are separate from the statutory appeal filing fee.

How to File Income Tax Appeal Online: Step-by-Step Procedure

First appeals are generally filed electronically through the Income Tax e-Filing Portal, following the procedure and form applicable to the relevant tax period.

Log In to the Income Tax Portal

Visit the official Income Tax e-Filing Portal and log in using the taxpayer’s PAN or TAN credentials, as applicable.

Open the Appeal Filing Facility

Depending on the applicable form and current portal interface, navigate through:

Pending Actions > e-Proceedings > For Your Information > File Appeal

Alternatively, use:

e-File > Income Tax Forms > File Income Tax Forms

Select Form 35 or Form 99 under the correct statutory category.

Select the Relevant Assessment Year or Tax Year

Select the relevant assessment year under the 1961 Act or tax year under the 2025 Act, as applicable.

Identify the order under appeal using its DIN, order number, date and relevant statutory provision.

Provide Appeal Details

Complete the required particulars concerning the appellant, assessing authority, order, demand, taxes paid, other pending appeals and appeal fee.

Upload the Statement of Facts and Grounds of Appeal

Prepare issue-wise Grounds of Appeal and an accurate Statement of Facts. Upload the required documents and supporting annexures.

For Form 99, the Department’s instructions also require identification of documentary evidence and disclosure of any additional evidence sought to be admitted.

Verify and Submit the Appeal

Review every field before submission. Complete verification using the prescribed DSC or EVC facility, as applicable.

Preserve the acknowledgement number, transaction ID, filing receipt and complete copy of the submitted appeal documents.

Practical recommendation: Before submitting, reconcile the dates, amounts and statutory sections against the assessment order and notice of demand. Avoid waiting until the last day, particularly where multiple attachments are required.

How to Prepare a Statement of Facts for an Income Tax Appeal

The Statement of Facts should explain the relevant history of the case clearly and chronologically.

It generally covers:

• The taxpayer’s relevant business or income activity.
• The return filed and income declared.
• Selection or initiation of assessment proceedings.
• Notices and important queries raised by the Department.
• Explanations and documents submitted during assessment.
• The disputed addition or disallowance.
• The taxpayer’s factual position regarding that dispute.

Illustrative Statement of Facts

Assume that a company filed its income tax return declaring income of Rs. 20 lakh. During scrutiny, the Assessing Officer questioned business expenses of Rs. 8 lakh and subsequently disallowed the entire amount.

A concise Statement of Facts might explain that the expenses were recorded in the books of account, the relevant invoices and payment details were submitted during assessment and the Assessing Officer made the disallowance for the reasons recorded in the order.

The Statement of Facts should objectively present the sequence and supporting records without substituting lengthy legal arguments for the factual background.

These figures are hypothetical and do not relate to any particular EzyBiz client or case.

How to Draft Effective Grounds of Appeal

Grounds of Appeal identify the precise findings, additions, disallowances or legal defects that the taxpayer is challenging.

They should be concise, specific and structured so that the appellate authority can determine the issues requiring adjudication.

Illustrative Grounds of Appeal

Continuing the hypothetical expense-disallowance example:

1. That the Assessing Officer erred in law and on the facts in making a disallowance of Rs. 8,00,000 in respect of business expenditure claimed by the appellant.
2. That the Assessing Officer failed to properly consider the invoices, books of account and payment records submitted during assessment in support of the expenditure.
3. That the appellant disputes the consequential computation of income and tax demand arising from the impugned disallowance.

The actual Grounds of Appeal must be tailored to the assessment findings, documents and statutory provisions.

Separate grounds should be considered for genuine jurisdictional or procedural objections, such as limitation, invalid initiation of proceedings or denial of a required opportunity of hearing.

For Form 99, the official filing guidance prescribes a limit of 100 words for each individual Ground of Appeal. The available form instructions should be followed when drafting and uploading grounds.

Can Additional Evidence Be Submitted During an Income Tax Appeal?

Additional evidence is evidence that was not produced before the Assessing Officer during the original proceedings.

Its admission is not automatic.

For proceedings governed by the Income-tax Act, 1961, Rule 46A of the Income-tax Rules, 1962 is particularly relevant.

For proceedings governed by the Income-tax Act, 2025, Rule 192 of the Income-tax Rules, 2026 prescribes corresponding restrictions and conditions.

Depending on the facts, additional evidence may be permitted in specified circumstances, including where:

• The Assessing Officer refused evidence that ought to have been admitted.
• Sufficient cause prevented the taxpayer from producing evidence requested during assessment.
• Sufficient cause prevented the taxpayer from producing evidence relevant to a Ground of Appeal.
• The order was made without giving a sufficient opportunity to produce relevant evidence.

The taxpayer should explain the relevance of the documents and why they were not produced earlier. The prescribed procedure also protects the Assessing Officer’s opportunity to examine or respond to the additional material where required.

Practical recommendation: Prepare a separate, reasoned application for additional evidence wherever required. Do not assume that uploading new documents automatically makes them admissible.

What Happens After Filing an Income Tax Appeal?

After submission, the appeal is processed and assigned in accordance with the applicable appellate and administrative arrangements.

The appellate authority may issue notices, seek written submissions, obtain further information, call for a remand report or provide hearing opportunities in accordance with the governing procedure.

The taxpayer should monitor the e-Filing Portal and registered email address for communications.

Written submissions should ordinarily address each Ground of Appeal separately, explain the assessment finding, identify the relevant documentary evidence and set out the legal arguments with appropriate references.

Electronic and Faceless Appeal Proceedings

Many first appeals are administered electronically through the applicable faceless or e-Appeal framework.

Depending on the governing scheme and proceeding, communication, document submissions, allocation of appeals and hearings may be managed electronically.

Where a video hearing is available or required under the applicable procedure, the request should be made through the prescribed facility.

For a more detailed explanation, refer to Faceless and Electronic Income Tax Appeals in India.

Does Filing an Income Tax Appeal Stop Recovery of Demand?

No. Filing an income tax appeal does not automatically suspend recovery.

Where a substantial disputed demand has been raised, the taxpayer should consider filing a separate stay application before the appropriate authority.

For proceedings governed by the Income-tax Act, 1961, section 220(6) provides the relevant Assessing Officer-stage relief framework during qualifying appeals.

Under the Income-tax Act, 2025, section 411 contains the corresponding payment and default framework.

The merits of the dispute, financial hardship, amounts already paid and applicable CBDT guidelines may be relevant when seeking stay.

For detailed guidance, see Stay of Income Tax Demand After Assessment Order in India.

What Powers Does the First Appellate Authority Have?

The first appellate authority can examine the appeal and exercise the powers granted by the governing Income-tax Act.

In an appeal against an assessment, the authority may have power to confirm, reduce, enhance or annul the assessment.

Under section 360 of the Income-tax Act, 2025, the relevant appellate authority is empowered to grant the remedies specified by the statute. The Act also provides specific powers concerning certain best judgment assessment cases.

Enhancement of assessment or penalty, or reduction of refund in circumstances covered by the relevant provision, requires an appropriate opportunity for the appellant to respond.

The first appeal may therefore result in full relief, partial relief, confirmation of the order or an adverse outcome within the appellate authority’s statutory powers.

The appellant should prepare carefully because the appellate authority may examine matters arising from the proceedings beyond the exact wording of the initially drafted Grounds of Appeal, within the applicable law.

What Happens After the CIT(A) or JCIT(A) Order?

Once the first appellate order is issued, review the decision against each Ground of Appeal.

If relief is granted, verify that the tax demand or refund is correctly recomputed and the appellate order is given effect by the Department.

If the taxpayer remains aggrieved by an appealable appellate order, a further appeal may lie before the Income Tax Appellate Tribunal (ITAT), subject to the applicable statutory provisions, limitation period and fees.

For proceedings governed by the Income-tax Act, 1961, sections 253 and 254 are important Tribunal appeal provisions.

For proceedings governed by the Income-tax Act, 2025, sections 361 to 364 contain the corresponding Tribunal appellate framework.

Further appeals to the High Court ordinarily involve the statutory requirements concerning substantial questions of law. Supreme Court proceedings are governed by the applicable law and appellate provisions.

Common Mistakes When Filing an Income Tax Appeal

• Missing the filing deadline: Limitation must be calculated from the correct statutory starting point.
• Using the wrong form: Choose Form 35 or Form 99 according to the governing law.
• Failing to challenge an important addition: Review the order issue by issue before drafting Grounds of Appeal.
• Drafting vague grounds: Identify the exact disputed finding and relief requested.
• Providing inconsistent facts: Reconcile the Statement of Facts with the assessment record.
• Uploading additional evidence without justification: Follow the applicable admission rules.
• Incorrect fee payment: Determine the filing fee from the relevant statutory category.
• Ignoring demand recovery: Consider a stay application where appropriate.
• Failing to monitor the portal: Respond promptly to appellate notices and requests.
• Overlooking the appellate effect order: Verify that relief is correctly reflected in the demand or refund.
