CMA Inter Paper 7 (DITX) common mistakes
CMA Inter Paper 7 (DITX) · Understand the traps and how to avoid them.
Treating the 182-day rule as the only test for resident status and ignoring the 60-day plus 365-day test, and forgetting that the 60-day threshold becomes 182 days for an Indian citizen leaving India for employment or as crew, or for a citizen/PIO visiting India.
Candidates memorise '182 days' from coaching summaries and never build the two-step section 6(1) structure (basic condition 1, basic condition 2, then the deemed-resident rules of section 6(1A)). The special carve-outs for seafarers, employment abroad and visiting PIOs get lost because they are exceptions to the exception.
What to do instead
Draw a decision tree before attempting any residential status question: (a) is the individual in the listed exception categories? (b) apply 182 days; (c) if not, apply 60+365; (d) check deemed residence under 6(1A) for citizens/PIOs with Indian income above Rs 15 lakh and non-residence in 7 prior years; (e) then test ROR/RNOR under 6(6). Practise at least three fact patterns per branch until the tree is automatic.
Computing salary income without first deciding whether the taxpayer is on the old regime or the new section 115BAC regime, then mixing exemptions (HRA, LTA, 80C) into the new regime computation.
Many candidates learned the old regime first and treat the new regime as an add-on. Since the new regime is the default and most exemptions and Chapter VI-A deductions (other than 80CCD(2), 80JJAA and a few others) are withdrawn, applying old-regime exemptions inside it produces a wrong total income even when every individual line item is arithmetically correct.
What to do instead
At the top of every computation, write one line: 'Regime assumed: 115BAC default / old regime opted under 115BAC(6)'. Then strike out every exemption and deduction not permitted in the chosen regime before doing any arithmetic. If the question is silent and asks for the better option, compute both totals side by side in two columns.
For house property, deducting the full 30% standard deduction and interest on borrowed capital against rent that is not actually received, and ignoring the annual value ceiling of municipal value versus fair rent versus standard rent versus actual rent.
Candidates jump straight to the 30% deduction because it is the most memorable number in section 24, skipping the section 23(1) determination of annual value. Unrealised rent and vacancy allowance under rule 4 are also commonly omitted because they appear later in the chapter.
What to do instead
Use a fixed four-step template: (1) determine gross annual value as the higher of expected rent (municipal value or fair rent, subject to standard rent) and actual rent received or receivable, reduced for vacancy; (2) deduct municipal taxes actually paid by the owner; (3) deduct 30% of net annual value; (4) deduct interest under section 24(b), with the Rs 2 lakh pre-construction cap for self-occupied property. Do the steps in order every time.
Claiming depreciation under section 32 on a block of assets while also deducting the full capital cost of the same asset as a business expense, or forgetting that depreciation is mandatory and that the block's written-down value must be reduced even if no depreciation is claimed.
Candidates treat depreciation as optional like a Chapter VI-A deduction. They also forget that for assets used for less than 180 days in the year of acquisition, only half the normal rate applies, and that the block ceases to exist when the WDV falls to zero.
What to do instead
Memorise three rules as a checklist: depreciation is compulsory; half-rate applies for assets put to use for fewer than 180 days in the year of acquisition; and the block's WDV is reduced by the depreciation actually allowable, not by what the assessee chooses to claim. When an asset is sold, reduce the sale proceeds from the block and compute the short-term capital gain only if the block is exhausted.
Applying the 20% long-term capital gains rate to listed equity shares or equity-oriented mutual funds instead of the special 12.5% rate under section 112A, and using the wrong cost inflation index base year.
The Finance Act 2024 changes (12.5% rate, Rs 1.25 lakh section 112A exemption, removal of indexation for most assets) are recent, and candidates rely on older study material or memory. The base year for the cost inflation index was shifted to 2001-02, and many still use 1981-82.
What to do instead
Build a one-page table of capital gains rates by asset class: listed equity and equity MF under 112A at 12.5% above Rs 1.25 lakh; other long-term assets at 12.5% without indexation; short-term listed equity at 20% under 111A; other short-term at slab rates. Note the 2001-02 base year and that indexation is available only for assets where it is specifically preserved. Re-verify the table against the current Finance Act before the exam.
Deducting Chapter VI-A deductions from gross total income before applying the special-rate incomes (112A, 111A, 112) and then applying the slab rates to the residue.
Candidates learn 'GTI minus Chapter VI-A equals total income' as a single formula and apply it mechanically. Chapter VI-A deductions cannot be set against special-rate income, and the order of computation (normal income first, then special-rate income, with deductions restricted to normal income) is easy to miss.
What to do instead
Compute in this order: income under each head, aggregate to GTI, separate special-rate income, apply Chapter VI-A deductions only against normal income (subject to the overall cap), then tax normal income at slab rates and special-rate income at its own rate. Show the two streams as separate columns in the working notes.
Filing a belated return and then assuming losses can be carried forward, or assuming a revised return can be filed after the belated return deadline.
Candidates conflate the section 139(1) due date, the section 139(4) belated return date and the section 139(5) revised return window. The rule that business losses and capital losses cannot be carried forward if the return is belated (except unabsorbed depreciation and house property loss) is a frequent trap.
What to do instead
Memorise the three dates as a timeline: original return under 139(1); belated return under 139(4) up to 31 December of the assessment year; revised return under 139(5) up to the end of the assessment year. Add a note that belated returns forfeit carry-forward of business and capital losses, and that a loss return must be filed on time to preserve the carry-forward.
Deducting TDS at the wrong rate or threshold because the candidate uses the old section 194A/194C/194J limits and does not check whether the payee has furnished a PAN or a lower-deduction certificate.
TDS thresholds and rates change almost every Finance Act, and the consequences of a missing PAN (tax deducted at the higher rate under section 206AA) are a separate rule that candidates forget to apply. Candidates also miss that TDS on salary is governed by the employee's regime choice.
What to do instead
Maintain a TDS grid with columns: section, nature of payment, threshold, rate, higher-rate trigger under 206AA, and due date. Before computing, check three things: has the payee furnished a valid PAN, is there a lower or nil deduction certificate under 197, and which regime has the employee opted for. Reconcile the grid with the current Finance Act each attempt.
Labelling every arrangement that reduces tax as 'tax avoidance' or 'evasion' without applying the specific tests (legal form versus substance, colourable device, section 96 to 102 of the Income-tax Act on impermissible avoidance arrangements).
The three terms are taught as a vocabulary list rather than as tests. Candidates cannot distinguish a legitimate exemption claim, an arrangement lacking commercial substance, and concealment of income, so they misclassify fact patterns.
What to do instead
Learn one diagnostic question per category: evasion involves illegality or concealment (false invoices, unrecorded receipts); avoidance uses legal means to defeat the intent of the law (round-tripping, treaty shopping, arrangements without commercial substance); planning uses incentives the legislature intended (80C, SEZ, specified deductions). Then map the fact pattern to the specific provision, such as GAAR under section 95 to 102 or the specific anti-avoidance rules under 94A to 94B.
Applying the arm's-length price test only to one transaction type and ignoring the specified domestic transaction thresholds, the most appropriate method selection, and the secondary adjustment and safe harbour rules.
Candidates treat transfer pricing as a single 'compare with unrelated price' step. They forget that section 92BA covers specified domestic transactions above the aggregate threshold, that the most appropriate method must be justified among the five prescribed methods, and that the advance pricing agreement route exists.
What to do instead
Structure every transfer pricing answer as: (1) identify associated enterprises and international or specified domestic transactions; (2) check the threshold; (3) select and justify the most appropriate method among comparable uncontrolled price, resale price, cost plus, profit split and transactional net margin; (4) compute the arm's-length price and the adjustment; (5) mention secondary adjustment, safe harbour and APA options where relevant.
