Working Through H.C. Mehrotra for Current Year Income Tax Problems
The book is still the most accessible reference for anyone tackling Indian income tax calculations, especially if you're sitting for CA, CS, or university exams. The 2024-25 edition covers the Finance Bill amendments that came into effect from April 1, 2024, which is where a lot of students and practitioners trip up because they're still solving problems using the old slab rates. Official PDF versions circulate on various educational forums and document-sharing platforms. The legitimate route is through the publisher's website or authorized e-book retailers. Many students end up with older editions accidentally, and the page numbers shift between versions, which causes confusion when cross-referencing with solved examples. Verify the copyright year before downloading anything. The 2024-25 edition will explicitly mention the assessment year 2024-25 on the title page. I spent about three hours last year trying to locate the correct PDF because my first download turned out to be the 2023-24 version. The chapter on capital gains had entirely different long-term holding period definitions in it, and I was solving problems assuming 24 months for immovable property when the new threshold had already shifted. Once I confirmed the edition, the rest was straightforward.
How the Book Is Structured and What It Actually Covers
It follows the standard Income Tax Act structure: computation of total income head by head, starting with salary, house property, profits and gains of business or profession, capital gains, and other sources. Then it moves into deductions under Chapter VI-A, set-off and carry forward of losses, and special provisions for specific categories of taxpayers. The solved examples are the real value here. They walk through the actual computation sequence, including the interplay between section 44AD and section 44ADA, which trips up a lot of people who try to claim both simultaneously. The book makes clear you can only elect one, but beginners keep missing that line. One thing the book doesn't handle well is the new tax regime under section 115BAC, particularly the amendments that took effect in FY 2023-24. The old regime chapters are still useful for understanding the underlying sections, but if you're preparing for current year problems, you need to supplement this with the latest CBDT circulars and notification updates. The book's coverage of the new regime is surface-level at best.
Practical Usage: A Problem That Isn't Straightforward
Last month I was helping someone with a case involving section 80TTB and section 80TTA overlap for a senior citizen who had both savings account interest and fixed deposit interest. The book presents these as separate heads under "Other Sources," but it doesn't clearly address what happens when the aggregate crosses the threshold in a way that triggers the higher exemption limit under 80TTB. The workaround is to aggregate all interest income first, then apply 80TTB up to the 50,000 limit, and any remaining interest above that gets checked against the 80TTA 10,000 ceiling. The book implies this but doesn't lay it out as a step-by-step computation, so I ended up drafting a separate flowchart for the person. Another edge case that the 2024-25 edition handles poorly is the interaction between the revised surcharge rates and the new tax regime option. When your total income crosses the higher surcharge thresholds, the effective tax rate jumps noticeably, and the book's numerical examples often use clean slab boundaries that don't reflect real-world income levels where this actually matters.

What You Should Know Before Relying on It
The biggest limitation is that no printed book, no matter how frequently updated, stays current with the rapid pace of amendment notifications. The CBDT issues clarifications almost weekly during budget season, and those don't appear in the book until the next edition. If you're using this for actual tax filing work rather than exam preparation, you need to cross-reference with the Income Tax Department's official website and the latest Budget highlights. The book also assumes a certain baseline familiarity with legal terminology. Sections are referenced by number without always explaining the plain-language meaning, which is fine if you've already studied the Act, but frustrating if you're encountering it for the first time. Pair it with the bare Act text for those moments. For exam purposes, it remains one of the most practical resources available. The problem sets at the end of each chapter cover the range of scenarios that typically appear in CA and university papers. Just make sure you're solving them with the current year's rates and thresholds, not the ones printed in the examples if those have changed.
