Direct Taxes Ready Reckoner 2026-2027

Direct Taxes Ready Reckoner (DTRR) is the flagship annual reference publication of Taxmann. It is the most authoritative and comprehensive single-volume guide to Indian direct tax law, updated each year. First published in May 1978, the 50^th Golden Jubilee Edition commemorates fifty years of continuous publication under the same authorship. The DTRR 50^th Edition maps, compares, cross-references, and illustrates, serving simultaneously as a practitioner’s guide, a compliance checklist, a tax calculation resource, and a manual for legislative transition. All section references default to the Income-tax Act 2025, and all rule references default to the Income-tax Rules 2026, unless explicitly indicating the 1961 Act—a deliberate editorial choice that facilitates the profession’s transition to the new legal framework.

The 50^th Edition operates amid unprecedented regulatory complexity: the Income-tax Act 2025, and the Income-tax Act 1961 run concurrently—pre-2025 assessments under the old Act, new assessments under the new. The Finance Bill 2026, amends both simultaneously, with differing effective dates. The Income-tax Rules 2026, further replace the 1962 Rules entirely—renumbering sections, redesignating forms, and restructuring procedural timelines across TDS, TCS, and return filing. The DTRR 50^th Edition addresses all three layers in a single volume.
