Professional alert

Connected Income-tax Rules, 2026 and Forms

No provision-specific Rule/Form is independently mapped in this tranche. General return, procedure and evidence rules can still apply.

Worked application

Two banking entities amalgamate under a qualifying Central Government scheme. Before claiming predecessor losses, the amalgamated bank should map each amount to the statutory category, original tax year and the conditions of the approved scheme.

Evidence / compliance checklist

  • Build a section 117 loss ledger showing source, head, tax year of origin, amount used and balance carried forward.
  • Preserve the timely return and assessment/intimation that determines the loss where the statute makes filing a condition (section 117: Treatment of accumulated losses and unabsorbed depreciation in scheme of amalgamation in certain cases).
  • For reorganisations, retain scheme orders, ownership continuity, asset/business continuity and predecessor-successor tax records (section 117: Treatment of accumulated losses and unabsorbed depreciation in scheme of amalgamation in certain cases).
  • Prevent double use by reconciling the carry-forward schedule to each later return before set-off (section 117: Treatment of accumulated losses and unabsorbed depreciation in scheme of amalgamation in certain cases).

Common mistake

Using a single “loss carried forward” figure for section 117 without preserving head/source restrictions, filing conditions and the remaining statutory period.

Recommended approach

For section 117, fix the governing tax year, identify the operative sub-section for “Treatment of accumulated losses and unabsorbed depreciation in scheme of amalgamation in certain cases”, trace every amount to evidence, apply only verified Rule/Form links, and retain a computation that another reviewer can reproduce from the primary source.

Judicial / interpretive bridge
