How to File an Income Tax Appeal Against an Assessment Order
Received an assessment order with disputed additions, disallowances or an incorrect demand? This practical guide explains the first appeal procedure, required forms, filing deadlines, fees, supporting documents and ways to seek protection against recovery.
1. What is an income tax appeal?
An income tax appeal is a statutory remedy by which a taxpayer challenges an appealable order of an income tax authority before a designated appellate authority. An assessment order determines taxable income, loss or tax liability after examination of a return or other proceedings. An assessee is a person within the meaning of the applicable Act who is liable to tax or is subject to relevant proceedings. A notice of demand communicates the amount payable pursuant to an order.
The first appeal generally lies to the Joint Commissioner (Appeals) or Commissioner of Income-tax (Appeals), depending on the statutory allocation of jurisdiction. It is not an automatic rehearing of every issue: identify the specific findings, facts and legal errors being challenged.
2. Which law and appeal form apply?
| Underlying proceeding | Governing law | First appeal |
|---|---|---|
| Earlier assessment years, including AY 2026-27 and prior years | Income-tax Act, 1961, as preserved by section 536 of the 2025 Act | Form 35; sections 246A, 248-250 as applicable |
| Tax year beginning 1 April 2026 or later, where governed by the new Act | Income-tax Act, 2025 | Form 99 under section 358 and applicable Income-tax Rules, 2026 |
| Appeal pending on 1 April 2026 | Continues under saved 1961 Act provisions | Normally no fresh appeal merely because of the new Act |
Under the 2025 Act, section 357 addresses appealable orders, section 358 deals with the form of appeal, fees and limitation, and section 359 addresses appellate procedure. Under the 1961 Act, the corresponding framework includes sections 246A, 249 and 250. Check the provision cited in the assessment order and the tax period before filing.
3. Which assessment orders can be appealed?
Depending on the applicable statute, appealable matters may include scrutiny assessments, best judgment assessments, reassessments, eligible adjustments in processing intimations, certain rectification orders and penalty orders. A taxpayer may contest additions to income, rejection of exemptions or deductions, disallowance of expenses, unexplained credits, procedural defects or errors in computation. Not every communication is independently appealable; read the order and the statutory list of appealable orders.
4. Time limit and appeal fees
Ordinary deadline: 30 days. For assessment or penalty appeals, the statutory clock ordinarily runs from service of the related notice of demand; for other appealable orders, it ordinarily runs from service of the relevant order or intimation. Record the actual service date, not merely the date printed on the order. Applicable exclusions and computation rules may affect the last day.
| Total income assessed by AO | Appeal fee |
|---|---|
| Rs. 1,00,000 or less | Rs. 250 |
| Above Rs. 1,00,000 up to Rs. 2,00,000 | Rs. 500 |
| Above Rs. 2,00,000 | Rs. 1,000 |
| Other matters outside these categories | Rs. 250 |
The appellate authority may condone a delayed appeal on sufficient cause, supported by an explanation and evidence. Under section 358(6) of the 2025 Act and corresponding provisions of the 1961 Act, conditions relating to payment of tax on returned income or advance tax may also affect admission. Check these requirements before submission.
5. How to file an appeal online: step-by-step
- Download the complete record: assessment order, demand notice, computation sheet, relevant notices, replies and proof of service.
- Identify the correct Act and form: use Form 35 for saved 1961 Act matters or Form 99 for matters governed by the 2025 Act.
- Prepare the Statement of Facts: explain the return filed, notices received, documents submitted, findings and disputed additions chronologically.
- Draft separate Grounds of Appeal: challenge each material error of fact, law or procedure and specify the relief requested.
- Pay the applicable appeal fee: retain the challan or payment reference.
- Log in to the Income Tax e-Filing Portal: select the appropriate statutory appeal form in the available filing services and follow the current portal workflow.
- Enter order details: PAN, tax period, DIN/order number, dates, disputed demand, tax paid and related proceedings as requested.
- Upload supporting documents: order, notice of demand, grounds, facts, fee proof and other relevant records; request condonation where necessary.
- Verify and submit: complete the prescribed electronic verification and save the acknowledgement and filed form.
- Monitor the appeal: respond within deadlines to notices, hearing opportunities and requests for additional information.
6. How to draft the Statement of Facts and Grounds of Appeal
The Statement of Facts should be factual, concise and supported by the assessment record. The Grounds of Appeal should separately identify the contested additions or legal errors. Avoid generic allegations without connecting them to the assessment findings.
Illustrative grounds of appeal
1. The Assessing Officer erred in law and on facts in making an addition of Rs. [amount] without properly considering the documentary evidence filed during assessment proceedings.
2. The Assessing Officer erred in disallowing Rs. [amount] claimed as [deduction or expense], despite the supporting records and applicable statutory requirements.
3. The appellant prays that the disputed addition or disallowance be deleted and the consequential tax demand and interest be recomputed in accordance with law.
4. The appellant seeks permission to add, amend or withdraw grounds in accordance with the applicable appellate procedure.
These are examples, not grounds suitable for every case. For alleged denial of natural justice, identify the notice, opportunity or material concerned. If relying on new evidence, examine the applicable rules for admission of additional evidence rather than assuming it will automatically be accepted.
7. Does filing an appeal stop recovery of tax demand?
No. Filing an appeal does not by itself stay recovery. Where a demand is disputed, separately seek appropriate stay or treatment as not being in default from the competent authority under the applicable statutory framework. Explain the prima facie merits, financial hardship, balance of convenience and amounts already paid. Any stay may be subject to conditions; do not assume that a fixed percentage deposit is mandatory in every case.
Also check whether the dispute concerns a simple apparent mistake, such as a tax credit mismatch, for which rectification may be appropriate. A rectification request and an appeal serve different purposes, and a rectification application should not be assumed to extend the appeal limitation period.
8. Hearing, appellate order and further remedies
Appeal proceedings may be conducted through the faceless appellate system where applicable. The authority can examine the grounds, seek further inquiry, admit additional grounds subject to statutory conditions and issue a reasoned order. Depending on the facts and law, the assessment may be confirmed, reduced, enhanced or annulled. Enhancement is subject to the prescribed safeguards and opportunity of hearing.
If the first appellate decision remains adverse, an eligible further appeal may lie before the Income Tax Appellate Tribunal (ITAT), followed by the High Court on a substantial question of law and, where maintainable, the Supreme Court. Each stage has its own limitation and procedural requirements.
9. Frequently asked questions
Can I appeal after 30 days?
Yes, an application for condonation may be considered if sufficient cause is established. Acceptance is discretionary and should not be presumed.
Should I use Form 35 or Form 99 in November 2026?
Use the form applicable to the underlying proceeding: generally Form 35 for matters saved under the 1961 Act and Form 99 for proceedings governed by the 2025 Act. The filing date alone does not decide the form.
Must I pay the entire disputed tax before filing?
Not necessarily. Distinguish the statutory admission requirement concerning tax on returned income or advance tax from the disputed additional demand. Recovery or stay is a separate question.
Can I file an appeal without a lawyer?
Taxpayers may file electronically themselves, although professional assistance is often useful where facts, evidence, jurisdiction or substantial additions are disputed.
Can I request a stay of recovery with the appeal?
Yes, but a separate, properly addressed stay request may be required. An appeal filing alone does not suspend recovery.
