Why Did Form Numbers Change?
The Income Tax Act, 2025 completely restructured the legal framework. New IT Rules 2026 renumber all forms to align with the new section numbering under the 2025 Act.
When Do New Forms Apply?
New form numbers apply from April 1, 2026 (Tax Year 2026-27 onward). For FY 2025-26 filings, continue using old form numbers under IT Rules 1962.
What Are “New Forms”?
Some compliance requirements existed under the 1962 Rules but had no dedicated form. The 2026 Rules create new dedicated forms for these — shown with a dashed border.
Merged Forms
Where multiple old forms served a single purpose, they have been consolidated into one new form under IT Rules 2026 — reducing redundancy and simplifying compliance.
