A transition guide for taxpayers with pending assessments, appeals, rectifications, or demands from old years after the Income-tax Act, 2025 starts.

This guide is for Indian taxpayers, founders, finance teams, and return filers navigating the Income-tax Act, 2025 and Finance Act 2025 changes. Always verify the position against the official portal, notified forms, and the taxpayer's own documents.

The pending assessment 2026 change in context

The arrival of a new law does not automatically close out old-year tax proceedings. An assessment order issued for AY 2022-23, a rectification application filed under the old Income Tax Act 1961, or a pending CIT(A) appeal — each of these continues under the procedural rules applicable to it, not the new statute. The Income-tax Act, 2025 handles its own proceedings; the old Act handles the years it governed.

Point	Practical meaning
1	Pending old-year proceedings need their own document folder.
2	The applicable law, year, and notice section should be checked before replying.
3	Do not merge old appeal issues into current-year return working papers.

The risk of mixing up the two frameworks is real. Citing a section from the Income-tax Act, 2025 in a reply that concerns an AY under the old Act, or using an old form number in a proceeding that has moved to the new portal form, introduces errors that are difficult to correct after the fact.

Practical effect of pending assessment 2026

April 2026 onwards, Work on the AY 2026-27 return, Tax Year 2026-27 ongoing compliance, pending old-year appeals, and newly notified forms can all land in the taxpayer's queue during the same month. Without a clear filing system, it is easy to conflate the period, law reference, or procedural route for different proceedings.

A well-organised file for each pending proceeding should include the assessment year, the statute under which it was initiated, the specific sections cited in the notice or order, the current portal status, and the relevant evidence. Keep that file separate from the AY 2026-27 return working papers.

Example using pending assessment 2026 records

Take a taxpayer with a pending appeal at CIT(A) level for AY 2022-23. That taxpayer should maintain a separate folder containing: the original assessment order, the grounds of appeal, the evidence index, the demand notice and current outstanding amount, any stay order obtained, correspondence with the AO, and the latest hearing notice or portal status. None of this should be mixed into the current-year ITR working papers, even if some of the disputed income relates to amounts also reflected in later years.
