The publication also notes that the Income-tax Rules, 2026 and the prescribed forms were notified on 20 March 2026, which completed the main legal framework for the new income-tax law. The preface says ICAI’s Direct Taxes Committee had given suggestions on the new law and draft rules, and more than 150 recommendations were accepted across the Income-tax Act, 2025 and the Income-tax Rules, 2026.

The release of this second edition is important for tax professionals because the new law has replaced the old section structure with a fresh layout. The tabular mapping in the book will help readers trace corresponding provisions under the Income-tax Act, 1961 and understand the new Act with less confusion. The publication is expected to be a useful reference book for practice, study and day-to-day tax work.
