CA Inter Advanced Accounting mock test Jan 2027: AS-wise map
A good CA Inter Advanced Accounting mock test for Jan 2027 is built around the Accounting Standards, because ICAI's Paper 1 is. Across the three Paper 1s ICAI set in 2026 (January, May, September), nine standards came up every single time: AS 2, 3, 11, 13, 14, 15, 16, 20 and 21. The other AS rotate between the MCQ case scenarios and the compulsory Question 1. Below: the AS-by-AS map, one AS sum worked from ICAI's own answer, and what ICAI's examiners said students got wrong.
Group I starts on 2 January 2027. Each Inter paper runs 2 to 5 PM, and the 15 minutes before it, from 1:45 PM, are for reading, according to ICAI's January 2027 exam notification (PDF) (opens in a new tab). That notification gives group dates only; if ICAI keeps the papers in number order, as it did in September 2026, Paper 1 is the first of them.
What a CA Inter Advanced Accounts mock test paper must copy
ICAI's three 2026 papers were built the same way:
| Part | What ICAI set | What your mock should have |
|---|---|---|
| Part I, 30 marks | 15 MCQs of 2 marks, most of them in three case scenarios | A case where one company's facts test 3 to 5 different AS |
| Question 1, 14 marks, compulsory | Three AS questions, about 5 + 5 + 4 marks | Three different standards, each a short computation |
| Questions 2 to 6, any four, 14 marks each | Amalgamation, consolidation, cash flow, Schedule III, reconstruction or buy-back | At least one full AS 14 and one full AS 21 question |
| Question 6 | An OR in 6(a), branch accounts in 6(c) | One theory-or-numerical choice, one branch question |
ICAI's instructions on the paper also say: "Working notes should form part of the answer." The marks for each part, paper by paper, are in CA Inter exam pattern Jan 2027.
CA Inter Advanced Accounting accounting standards: where each AS came in 2026
ICAI's syllabus lists 27 standards for Paper 1 (AS 1 to AS 29, without AS 6 and AS 8), plus the Framework, in Section I, which carries 55% to 65% of the paper (ICAI section-wise weightage, PDF (opens in a new tab)). Here is where each one was actually tested. The question numbers come from ICAI's January 2026 answers (PDF) (opens in a new tab), May 2026 answers (PDF) (opens in a new tab) and September 2026 paper (PDF) (opens in a new tab). The September paper is a scan, so its question numbers are our reading of the page images, and the AS tagging in all three is ours.
Asked in all three papers:
| Standard | January 2026 | May 2026 | September 2026 |
|---|---|---|---|
| AS 21 Consolidated statements | Q5 | Q5(a) | Q5 |
| AS 14 Amalgamations | Q4, MCQ 15 | Q4, MCQ 15 | Q3, Q2(b) |
| AS 3 Cash flow | MCQs 11–14 | Q3(a), MCQ 12 | Q4(a), MCQ 13 |
| AS 15 Employee benefits | Q1(b) | Q1(a) | MCQs 3, 5 |
| AS 16 Borrowing costs | Q1(a), MCQ 1 | MCQ 7 | Q1(a), MCQ 6 |
| AS 20 Earnings per share | Q1(c) | MCQ 5 | Q1(c) |
| AS 13 Investments | Q3(b) | MCQ 8 | MCQ 7 |
| AS 2 Inventories | MCQ 4 | MCQ 6 | MCQ 9 |
| AS 11 Foreign exchange | MCQ 2 | Q6(a) OR | MCQ 1, Q1(a) |
Asked in two of the three:
| Standard | January 2026 | May 2026 | September 2026 |
|---|---|---|---|
| AS 10 Property, plant and equipment | – | Q1(b), MCQs 4, 7 | Q1(a) |
| AS 25 Interim reporting | MCQ 8 | Q1(c), MCQ 10 | – |
| AS 29 Provisions | MCQ 5 | – | MCQs 4, 8 |
| AS 23 Associates | MCQs 3, 7 | MCQ 2 | – |
| AS 28 Impairment | – | Q1(b) | Q4(b) |

| AS 19 Leases | Q6(a) OR | – | Q1(b) |
| AS 24 Discontinuing operations | Q6(a) | Q5(b) | – |
| AS 7 Construction contracts | MCQ 6 | MCQ 3 | – |
| AS 18 Related parties | MCQ 10 | – | Q6(a) |
Once in the three: AS 4 (May MCQ 9), AS 5 (May Q6(b)), AS 9 (September Q6(a) OR), AS 22 (January MCQ 9) and the Framework (September MCQ 10).
What the map tells you
- The two big statements never move. AS 21 was Question 5 all three times and AS 14 was a full 14-mark question all three times. With their MCQs, they are about a quarter of the marks printed, as counted in our chapter-by-chapter marks table for Paper 1.
- Question 1 is where the smaller AS live. AS 10, 15, 16 and 20 each took a Question 1 part in two of the three papers, and AS 25, AS 28 and AS 19 in one each. Expect three standards you didn't prepare as "big chapters".
- The MCQ cases mix standards. September 2026's first case alone tested AS 11, 12, 15 and 29 on one company.
- AS 2 is quiet but constant: an MCQ every time, never a long question.
A worked AS 25 question, checked against ICAI's answer
AS 25 came in January 2026 as an MCQ and in May 2026 as both an MCQ and Question 1(c). ICAI's examiners wrote that in Q1(c) "many examinees were unable to correctly calculate the weighted average annual effective tax rate." Here is that question, with the figures and method from ICAI's May 2026 suggested answer (PDF) (opens in a new tab).
Facts: estimated income for 2025-26 is Rs 5,00,000, Rs 1,25,000 a quarter, including a capital gain of Rs 1,00,000 in the second quarter. Capital gains are taxed at 20%; other income at 35% on the first Rs 2,00,000 and 40% on the rest.
Step 1: total tax for the year.
| Item | Rs |
|---|---|
| 20% on capital gain of 1,00,000 | 20,000 |
| 35% on the first 2,00,000 of other income | 70,000 |
| 40% on the remaining 2,00,000 | 80,000 |
| Total tax expense | 1,70,000 |
Step 2: the weighted average rate, for other income only. 1,50,000 ÷ 4,00,000 = 37.5%. The capital gain keeps its own 20% rate; that is the trap. ICAI's answer cites para 29 of AS 25: tax in each interim period is based on the best estimate of the weighted average annual rate for the full year.
Step 3: tax for each quarter.
| Quarter | Working | Tax (Rs) |
|---|---|---|
| Q1 | 1,25,000 × 37.5% | 46,875 |
| Q2 | 1,00,000 × 20% + 25,000 × 37.5% | 29,375 |
| Q3 | 1,25,000 × 37.5% | 46,875 |
| Q4 | 1,25,000 × 37.5% | 46,875 |
| Total | 1,70,000 |
The quarters add back to the annual 1,70,000; if yours don't, the rate is wrong.
Check yourself on January 2026's MCQ 8: quarterly profits of Rs 7, 8, 4 and 6 lakh, tax at 30% on the first Rs 5 lakh and 40% above it. The year's tax is Rs 9.5 lakh on Rs 25 lakh, a 38% rate, so the second quarter's tax is 8,00,000 × 38% = Rs 3,04,000: option (C) in ICAI's answer key.
AS 10: what goes into the cost, from May 2026 Q1(b)
The examiners said "many examinees committed errors in determining the cost of the machine by incorrectly including the supplier's interest on deferred credit and expenditure incurred after the asset was ready for its intended use." ICAI's answer sorted the costs like this:
| Cost item | ICAI's treatment |
|---|---|
| Purchase price, less the GST credit available | In the cost |
| Site preparation, architect's fees for set-up | In the cost |
| Labour, only the 200 of 500 hours spent on installation | In the cost |
| Supervisor's salary, only the 25% spent on installation | In the cost |
| Test run and experimental production | In the cost |
| Depreciation on assets used for installation | In the cost |
| Interest to the supplier for deferred credit | Out: charged to profit and loss |
| Costs after the machine was ready (Rs 10,800 for the delay) | Out: charged to profit and loss |
That gives a capitalised cost of Rs 8,10,000 and six months' depreciation of Rs 40,500. The question then moved to AS 28, where the impairment loss is set first against the revaluation reserve and only the rest goes to profit and loss.
May 2026 examiner comments for Paper 1, AS by AS
From ICAI's May 2026 Group I volume (PDF) (opens in a new tab), these are the comments on the AS questions:
| Question | Standard | What went wrong (our summary of ICAI's comment) | What to do in your mock |
|---|---|---|---|
| Q1(a) | AS 15 | Salary not projected at the 10% growth, so the obligation, service cost and interest cost all went wrong | Project the last salary first, then discount |
| Q1(b) | AS 10, AS 28 | Supplier's interest and post-ready costs put into cost; carrying amount after revaluation wrong | Sort every cost in or out before adding |
| Q1(c) | AS 25 | Weighted average annual rate wrong | Separate income taxed at its own rate |
| Q3(a) | AS 3 | Some items treated or classified under the wrong activity; some presentation errors | Decide operating, investing or financing for each item before you total |
| Q4 | AS 14 | Net assets and capital employed wrong, so debentures, goodwill or capital reserve wrong | Write purchase consideration as a working note |
| Q5(a) | AS 21 | Unrealised profit, inter-company income and expenses not eliminated | List every intra-group item before the statement |
| Q6(a) OR | AS 11 | Unclear when an exchange difference goes to profit and loss and when to the asset's cost | State the rule, then pass the entry |
| Q6(b) | AS 5 | Right answer (change in accounting policy) without the reasoning or the AS | Rule, application, conclusion |
ICAI's remaining Paper 1 notes (Schedule III, reconstruction entries, AS 24 and the convergence theory question) are quoted in our May 2026 examiner comments for all six Inter papers. How ICAI gives step marks for each of these lines is in step marking in CA exams.
CA Inter Advanced Accounting important topics for Jan 2027
From the map and the examiners' notes, in order:
- AS 14 and AS 21 as full questions, with working notes for purchase consideration, goodwill or capital reserve, minority interest and unrealised profit.
- AS 3 as a full statement, because it came both as a long question and as an MCQ case.
- The Question 1 standards as 5-mark sums: AS 10 with 28, 15, 16, 19, 20 and 25, about 9 minutes each.
- The quiet constants for the MCQ cases: AS 2, 11, 12, 13, 23 and 29. Know the rule and one number for each.
- Branch accounts for Question 6(c), plus internal reconstruction and buy-back, which shared the company-accounts questions.
The dates to give each of these, alongside Law and Taxation, are set out day by day in the Group I and Group II revision planner.
After each mock, tag every lost mark with its standard; an AS that costs you twice goes to the top of next week, whatever its weightage. The windows for Mocks 1, 2 and 3 before 2 January are in our three-mock calendar for CA Inter.
