ITAT Makes E-Filing Compulsory for Every Appeal, Effective 1 October 2026 — And Gives the Profession One Day’s Notice

Say a firm has filed every ITAT appeal the same way since 2009: a signed Form 36 memorandum, a paper book, a trip to the Registry counter, a stamped acknowledgement for the client file. It has worked for seventeen years. Then, on 30 September 2026, the Tribunal issues a Practice Note. From the very next day, that familiar counter no longer accepts a Memorandum of Appeal at all — not as an alternative, not as a backup, not for anyone.

Sourcing note: this article is based on reporting from TaxGuru, Studycafe and A2Z Taxcorp LLP of ITAT’s Practice Note, and TaxGuru’s published analysis of practitioner concerns. The Practice Note’s full text was not independently retrieved from ITAT’s own e-filing portal this cycle; readers with an imminent filing deadline should independently confirm current portal requirements.

The Note’s own words leave nothing to argument: a Memorandum of Appeal “not filed through the e-Filing Portal or not filed in the form prescribed… shall not be registered.” That is the entire effect of ITAT’s Practice Note F.31-AT/Gen.Adm./Central/Delhi/2025-26, dated 30 September 2026, issued under Section 255(5) of the Income-tax Act, 1961, read with Rule 6 of the Income Tax (Appellate Tribunal) Rules, 1963, as amended by the 2025 Amendment Rules.

Mechanically, the new regime covers more than the headline Memorandum of Appeal: Cross Objections, Stay Applications, Miscellaneous Applications, and every accompanying document requiring an appellant’s signature must now go through the designated portal (itat.gov.in/efiling), signed with a Digital Signature Certificate rather than by hand. PAN or TAN, a mobile number and an email ID serve as the filer’s portal identifiers. The date of upload is now the official date of presentation for limitation purposes. One transition provision softens the edges slightly: appeals already filed in physical mode before 1 October 2026 may continue submitting Paper Books and supporting documents physically — the new portal-only regime governs new filings, not the tail of matters already in the pipeline.

Sidebar: the gap between announcement and enforcement was exactly one day — a Practice Note dated 30 September took effect 1 October, no phased rollout, no pilot period. CA Amresh Vashisht’s analysis, published on TaxGuru on 3 October 2026, flags unresolved gaps: no stated outage protocol if the portal is down near a filing deadline, no clear correction process for a defective upload, no assisted-filing route at the Benches for a litigant without professional help, and an open question on whether “fresh” applications in matters that began under the old physical-filing regime follow the new rule or the old one.

Why It Matters

This is not a change to anyone’s tax liability, and it does not touch the substance of a single appeal. But procedure is exactly where appeals are won and lost before the merits are ever reached — a Memorandum of Appeal that simply never gets registered because it was filed the old way is, for all practical purposes, an appeal that was never filed at all, with the limitation clock running the entire time nobody noticed. Every CA, tax litigator, and in-house finance team managing live or anticipated ITAT matters needs this on their checklist today.

Key Takeaways

• From 1 October 2026, every Memorandum of Appeal, Cross Objection, Stay Application and Miscellaneous Application before ITAT must be filed through the e-Filing Portal with a Digital Signature Certificate — physical filing of a new matter will not be registered.
• Legal basis: Section 255(5), Income-tax Act, 1961, read with Rule 6 of the Income Tax (Appellate Tribunal) Rules, 1963 (as amended, 2025), operationalised via Practice Note F.31-AT/Gen.Adm./Central/Delhi/2025-26 dated 30 September 2026.
• The date of upload on the portal is now the official date of presentation — directly relevant to limitation computation.
• Appeals already filed physically before 1 October 2026 may continue submitting Paper Books and supporting documents physically.
• Practitioner commentary has flagged genuine, unresolved gaps — no stated outage protocol, no clear defect-correction route, no assisted filing for self-represented litigants.

Practical Implications

Any matter with an appeal, cross-objection, stay application or miscellaneous application due to be filed at ITAT from 1 October 2026 onward must go through the portal — there is no fallback. Firms should treat Digital Signature Certificate readiness as a filing prerequisite to check well before a deadline, given there is no confirmed outage protocol if the portal is unavailable close to a limitation date.

Action Checklist

• Confirm every partner, associate or authorised representative who signs ITAT filings holds a valid, portal-compatible Digital Signature Certificate.
• For any filing due in the coming weeks, build in portal-upload time well ahead of the limitation date, given the absence of a confirmed outage protocol.
• For matters already filed physically before 1 October 2026, continue physical submission of Paper Books as the transition provision allows.
• Where a fresh application is contemplated in an older, pre-1 October physical-filing matter, file it through the e-Filing Portal unless and until the Tribunal clarifies otherwise.
• Watch for any follow-up clarification or amendment addressing outage handling and defect correction.

Relevant Sections & Rules

Section 255(5), Income-tax Act, 1961; Rule 6, Income Tax (Appellate Tribunal) Rules, 1963, as amended by the 2025 Amendment Rules; Practice Note F.31-AT/Gen.Adm./Central/Delhi/2025-26, dated 30 September 2026.

FAQs

Can a Memorandum of Appeal still be filed physically if the e-Filing Portal is down near a deadline? The Practice Note states no outage or contingency protocol; practitioners should not assume physical filing will be accepted as a fallback.

Does this affect appeals already pending before 1 October 2026? Paper Books and supporting documents in already-physically-filed matters may continue to be submitted physically; whether a genuinely fresh application within such a matter must now be e-filed is not expressly addressed, and the cautious reading is that it should be.
