Master Guide to Income Tax Rules 2026 is Taxmann's flagship, rule-wise treatise on the Income-tax Rules 2026, notified vide G.S.R. No. 198(E), dated 20-03-2026, and brought into force as the subordinate legislative framework operationalising the Income-tax Act 2025. Spanning over 1,700 pages, the work undertakes a complete and systematic reconstruction of procedural income tax law in India under the new statutory regime. Every one of the 333 rules contained in the Income-tax Rules 2026 is addressed in a dedicated, self-contained commentary that maps the new rule to the following:

• Its parent provision in the Income-tax Act 2025
• The corresponding rule under the Income-tax Rules 1962
• The corresponding form (where applicable) under both the new and old frameworks

The treatise thus simultaneously functions as a rule-wise commentary, a comparative concordance and a transition manual for the change-over from the Income-tax Act 1961/Income-tax Rules 1962 regime to the Income-tax Act 2025/Income-tax Rules 2026 regime.
