Assessment Procedure for CA Final: Steps, Timelines & Key Distinctions

14 min read2 September 20265 viewsConferenza Conferenza

Assessment Procedure is the structured process by which the Income-tax Department verifies and assesses the tax liability of an assessee based on the return of income (ROI) filed or the department's own proceedings. For CA Final, this topic is high-weightage and tests both procedural knowledge and application to real scenarios. The procedure encompasses return filing timelines, defect curing, three distinct assessment routes, and the rights and obligations at each stage.

Return of Income: Filing Framework

Who Must File & When

An individual, HUF, partnership, company, or trust must file a return if their Gross Total Income (GTI) exceeds the applicable basic exemption limit, or if any of the mandatory filing conditions apply (e.g., aggregate bank deposits over ₹50 lakh, high turnover, profession income, investments, foreign assets). The due date for ROI filing depends on the assessee's category:

  • Individual / HUF (accounts not required to be audited): 31st July of the Assessment Year
  • Individual / HUF (accounts required to be audited): 30th September of the A.Y.
  • Company: 30th September of the A.Y.
  • Firm / LLP: 30th September of the A.Y.
  • Charitable trust / entity: 31st October of the A.Y.

Note: Verify the current-year due dates with the latest ICAI / CBDT circular, as these may be extended or amended for specific periods.

Exam tip: The distinction between audited and non-audited accounts is critical. A professional (doctor, lawyer, CA) with non-audit threshold income still follows the 31st July due date—this is a frequent trap.

Belated Return (Section 139(4))

If an assessee misses the original due date, they may file a belated return at any time before the end of the relevant Assessment Year. However, a fee is payable—the amount varies by income level and is capped at a specific limit for those with T.I. not exceeding ₹5,00,000. Verify the current fee amount with the latest ICAI handbook; historically, a low cap (e.g. ₹1,000) has applied to small taxpayers.

Critical restriction: A belated return cannot claim the benefit of deductions under Section 10AA (SEZ units) or certain other concessional regimes. This is a common exam question.

Revised Return (Section 139(5))

An assessee who has filed an original or belated return and discovers an omission or error may file a revised return at any time before three months prior to the end of the A.Y., or before completion of assessment, whichever is earlier. This is a narrower window than belated filing and applies only to genuine omissions, not to items already disclosed.

Exam pattern: Questions test whether the assessee has filed "revised" or "updated" returns—the terminology and eligibility are distinct.

Defective Return (Section 139(9))

If the return is not properly filled (e.g., verification missing, signatures absent, schedules incomplete), the Assessing Officer issues a notice requiring the assessee to rectify the defect within 15 days (or an extended period at the AO's discretion). If the defect is not cured within the stipulated time, the return is treated as if no return was furnished—i.e., the assessee is in default, and the AO may proceed under Section 144 (Best Judgment Assessment).

Verification of Return

The return must be verified (signed and dated) by the assessee or an authorised person. For a company, any director may verify on behalf of the Managing Director. For an LLP being wound up, the liquidator is the authorised verifier. For trusts and partnerships, designated partners or trustees must verify. This detail appears frequently in scenario-based questions.

Assessment Methods: The Three Routes

Once a valid return is received, the AO follows one of three assessment pathways:

1. Summary Assessment (Intimation) — Section 143(1)

Scope: The AO processes the return and makes only adjustments that are apparent from the face of the return. Common adjustments include:

  • Disallowance of depreciation inconsistent with unabsorbed depreciation shown in the preceding year's return.
  • Corrections of arithmetic errors.
  • NOT permitted: additions based on external information, questioning the veracity of documents, or disallowing deductions in excess of statutory limits without inquiry.

Timeline: The AO issues an intimation under Section 143(1) and demands payment within 30 days. The assessee cannot dispute the intimation; if they disagree, they must file a revised return before the assessment is completed.

Exam alert: Q.2 in your practice set tests the specific boundary of Section 143(1) adjustments—learn what is "apparent" vs. what requires investigation.

2. Scrutiny Assessment — Section 143(2)

Scope: The AO conducts a detailed examination. The notice for Scrutiny Assessment must be issued within three months from the end of the financial year in which the return is furnished. The AO can:

  • Examine all aspects of income, deductions, and computation.
  • Issue notices under Section 142 (calling for documents) and Section 148 (reopening).
  • Grant the assessee a hearing before finalising the assessment.

Procedure: After examination and hearing, the AO issues an order of assessment finalising the total income and tax liability. The assessee has a right to appeal to the CIT(A).

3. Best Judgment Assessment — Section 144

When initiated: The AO resorts to Section 144 when an assessee fails to comply with a notice under Section 142(1) (summons for documents/information). Before making the BJA, the AO must grant the assessee an opportunity of hearing, except where a notice under Section 142(1) was issued prior to the initiation of the BJA.

Scope of BJA: The AO applies his best judgment and determines the total income or loss. The AO is mandated to make a determination—it is not discretionary. The assessment is binding on the AO but is subject to appeal.

Exam nuance: Q.18 tests whether the AO "must" or "may" apply best judgment in Section 144—the answer is that the AO is mandated.

Updated Return of Income — Section 139(8A)

A recent addition to the procedural framework, the Updated ROI allows an assessee to file a return after the due date of filing (including extended date) and after furnishing an earlier return, to disclose income not previously reported. Key restriction: The Updated ROI cannot be filed if it results in a decrease in total tax liability compared to the earlier return. This deters reverse amendments and ensures the measure functions as a disclosure mechanism.

Comparative Timeline & Key Dates

Original ROI Filing (non-audited) 31 July
Original ROI Filing (audited / company) 30 Sept
Charitable Trust ROI Filing 31 Oct
Belated ROI (within A.Y.) 31 March
Revised ROI (before 3 months before A.Y. end or assessment, whichever earlier) Dynamic
Scrutiny Assessment Notice (within F.Y. end + 3 months) Within 3 months

Common Exam Pitfalls & Distinctions

  • Revised vs. Updated: Revised return corrects omissions in disclosed items and must be filed before 3 months prior to A.Y. end. Updated return discloses previously unreported income and can be filed anytime before assessment completion, but cannot reduce tax liability.
  • Belated return benefits: A belated return cannot claim deductions under Section 10AA (SEZ), and the fee is payable. However, it can still claim standard deductions, Section 80C, and carry forward losses from prior years.
  • Section 143(1) vs. 143(2): Section 143(1) is summary and limited to apparent adjustments; Section 143(2) is detailed scrutiny with full examination rights.
  • Mandatory filing conditions: Even if T.I. is below the basic exemption limit, an assessee must file if aggregate bank deposits exceed ₹50 lakh (or ₹1 crore in current accounts), or if business turnover exceeds applicable thresholds.
  • Age-based exemption limits: An individual aged 60–79 years has a higher exemption limit (e.g., ₹3,00,000), and those aged 80+ have an even higher limit (e.g., ₹5,00,000). However, if GTI exceeds the applicable limit, filing is mandatory regardless of age.

Practice Questions

Q1. An individual assessee furnishes his original return on the due date. Later, he discovers an omission in the original return. By what date can he furnish a revised return?

  1. At any time before the end of the relevant Assessment Year.
  2. At any time before three months prior to the end of the relevant Assessment Year, or before completion of assessment, whichever is earlier.
  3. At any time within 12 months from the end of the relevant Assessment Year.
  4. Within 30 days of discovering the omission.
Show answer & explanation

Correct answer: B. Section 139(5) permits a revised return to be filed to correct omissions or errors, but only within a strict window: before three months prior to the end of the Assessment Year, or before the completion of assessment, whichever is earlier. This ensures finality of assessment and prevents endless amendments. The key word is "omission"—if the item was already disclosed (even if incorrectly), filing a revised return may not cure it; instead, an appeal or rectification application under Section 154 may apply. Option A (end of A.Y.) is too permissive and confuses the belated return deadline.

Q2. A Charitable Trust's income, computed before allowing exemptions, exceeds the basic exemption limit. To claim exemption, it must furnish its Return of Income (ROI) by which date?

  1. 31st July of the Assessment Year.
  2. 30th September of the Assessment Year.
  3. 31st October of the Assessment Year.
  4. 31st March of the Assessment Year.
Show answer & explanation

Correct answer: C. Charitable trusts and other eligible entities (including certain co-operatives and political parties) have an extended due date of 31st October to file their ROI. This allows them additional time to finalise accounts and claim eligibility-based exemptions. Standard individuals and companies must file by 31st July (non-audited) or 30th September (audited or company), making the October date a distinguishing feature for trusts and non-profit entities.

Q3. If a person's Total Income (T.I.) does not exceed ₹ 5,00,000, and they file a belated return (under Section 139(4)), the fee payable for late filing is limited to what amount?

  1. ₹ 5,000
  2. ₹ 10,000
  3. ₹ 1,000
  4. No fee is payable.
Show answer & explanation

Correct answer: C. The Income-tax Act prescribes a fee for belated return filing, scaled by income level. For small taxpayers (T.I. not exceeding ₹5,00,000), the fee is capped at a low amount, historically ₹1,000. This concessional fee recognises the burden on small taxpayers and encourages voluntary compliance. Higher-income assessees pay a proportionally larger fee. Note: verify the current-year cap with the latest ICAI/CBDT material, as fee amounts are occasionally revised.

Q4. Mr. P (age 45, resident) is not required to file a return of income based on his T.I. For the P.Y. 2025-26, his aggregate deposit in one or more savings bank accounts amounted to ₹ 51,00,000. Is he obligated to file an ROI for A.Y. 2026-27?

  1. No, as the mandatory filing condition applies only if the total income exceeds the basic exemption limit.
  2. Yes, as the aggregate deposit in savings bank accounts exceeds ₹ 50 lakh.
  3. No, the condition applies only if the deposit is in a current account.
  4. Yes, the condition applies only to individuals.
Show answer & explanation

Correct answer: B. Section 139(1) imposes mandatory filing conditions independent of T.I. thresholds. One such condition is that an individual with aggregate deposits in one or more savings bank accounts exceeding ₹50 lakh during the previous year must file a return. This is a separate ground and applies regardless of whether T.I. exceeds the basic exemption limit. The deposit condition applies to both savings and current accounts; the ₹50 lakh threshold is for savings accounts, and ₹1 crore is typically for current accounts. Mr. P's deposit of ₹51 lakh in savings accounts triggers the filing obligation.

Q5. A return of income filed by an assessee is deemed defective. If the assessee fails to rectify the defect within the prescribed period of 15 days (or extended period), the return is treated as:

  1. A valid return filed on the day the defect period expires.
  2. A revised return.
  3. An invalid return (as if the assessee failed to furnish the return).
  4. A belated return.
Show answer & explanation

Correct answer: C. Section 139(9) states that if a return is defective and the assessee does not cure the defect within 15 days (or extended time), the return is treated as if no return was furnished at all. This is a harsh consequence: the assessee loses the benefit of the return filing and is in default. The AO is then at liberty to proceed under Section 144 (Best Judgment Assessment) without need for a formal notice under Section 142. This makes defect rectification critical and a common compliance pitfall.

Q6. Mr. Q (age 70, resident) has a gross total income of ₹ 4,90,000 (before Chapter VI-A deductions and before considering any exemption under Section 54/54F etc.) for A.Y. 2026-27. He has opted out of the default tax regime (Section 115BAC (1A)). What is his mandatory ROI filing requirement based on the basic exemption limit?

  1. Not mandatory, as his gross total income is below ₹ 5,00,000.
  2. Mandatory, as his gross total income exceeds ₹ 3,00,000.
  3. Not mandatory, as his gross total income is below ₹ 5,00,000.
  4. Mandatory, as his gross total income exceeds ₹ 2,50,000.
Show answer & explanation

Correct answer: B. An individual aged 60–79 years has a basic exemption limit of ₹3,00,000 (the exact amount may vary by year; verify with current ICAI material). Mr. Q, aged 70, has GTI of ₹4,90,000, which exceeds ₹3,00,000. Therefore, filing is mandatory. The filing obligation is based on GTI, not on T.I. after deductions or exemptions under Section 54/54F. Options A and C state the same incorrect conclusion; this is a test of whether you know the age-based exemption limit distinct from the standard ₹5,00,000 for individuals aged 40–59.

Q7. For a person other than a company or a firm, when is the due date for filing the Return of Income (ROI) for the Assessment Year (A.Y.) 2026-27, if their accounts are not required to be audited under the Income-tax Act or any other law?

  1. 30th November 2026
  2. 31st October 2026
  3. 31st July 2026
  4. 30th September 2026
Show answer & explanation

Correct answer: C. For individuals and HUFs whose accounts are not required to be audited, the standard due date is 31st July of the A.Y. This applies to most salaried employees, retirees, and small-business individuals. Professionals (CAs, doctors, lawyers) with income above certain thresholds must have audited accounts and therefore comply with the 30th September deadline. Confusing the audit threshold (often ₹60 lakh business turnover) with the due date is a frequent error.

Q8. A Best Judgment Assessment (BJA) under Section 144 is initiated when an assessee fails to comply with a notice issued under Section 142(1). Before making the BJA, the Assessing Officer (AO) must give the assessee an opportunity of being heard, except in which specific case?

  1. Where the AO has gathered relevant material against the assessee.
  2. Where the notice under Section 142(1) was issued prior to the making of the BJA.
  3. When the assessee is a non-resident.
  4. When the AO directs a Special Audit under Section 142(2A).
Show answer & explanation

Correct answer: B. The general rule is that before making a BJA, the AO must grant a hearing. However, the statute creates an exception: if a notice under Section 142(1) (calling for documents) was issued prior to the initiation of the BJA process, the AO is not obliged to grant a fresh hearing. The prior notice is deemed to have given the assessee an opportunity to respond, satisfying the procedural requirement. This saves time and prevents tactical delays by non-compliant assessees.

Q9. When performing a Summary Assessment (intimation) under Section 143(1), which of the following adjustments can the Assessing Officer make to the returned income?

  1. Disallowance of an expenditure based on questioning the veracity of supporting documents.
  2. Disallowance of depreciation claimed, which is inconsistent with the unabsorbed depreciation of the preceding year shown in the return.
  3. Disallowance of a deduction claimed in excess of the statutory limit based on information not apparent in the return.
  4. Addition of income based on material gathered from external sources.
Show answer & explanation

Correct answer: B. Section 143(1) is a limited, mechanical process. The AO can make only those adjustments that are apparent from the face of the return. Disallowance of depreciation inconsistent with the previous year's unabsorbed depreciation (shown in the return itself) is an apparent mathematical/logical inconsistency and falls within the scope. In contrast, questioning the veracity of documents (Option A), adding income from external sources (Option D), or making adjustments not obvious in the return (Option C) all require detailed scrutiny and belong to Section 143(2) assessments. This is a high-frequency exam question testing the boundary of Section 143(1).

Q10. Mr. K, the Managing Director of K & Co. Ltd. (a resident company), is out of India and cannot verify the company's Return of Income (ROI). Who is the authorised person to verify the ROI in this scenario?

  1. Any director of the company.
  2. The Secretary of the company.
  3. The Principal Officer of the company.
  4. Only a person holding a valid power of attorney from the Managing Director.
Show answer & explanation

Correct answer: A. The verification of a company's return may be done by any director, not just the MD. This recognises practical realities (MD absence, travel, illness) and permits delegation within the board. The Secretary or Principal Officer alone cannot verify without being a director; a power of attorney is unnecessary when a director is available. This flexibility applies because the director is a legal representative of the company and acts in fiduciary capacity. Exam tip: distinguish this from partnerships (where a designated partner must verify) and LLPs (where any designated partner or, if wound up, the liquidator, can verify).

Q11. An assessee files his return belatedly under Section 139(4). In this belated return, he cannot claim the benefit of:

  1. Standard deduction for salary income.
  2. Deduction under Section 80C.
  3. Deduction under Section 10AA (for SEZ Unit).
  4. Carry forward of loss under the head "Income from House Property".
Show answer & explanation

Correct answer: C. The statute restricts certain concessional deductions (notably Section 10AA, relating to SEZ unit income) to assesses who file within the original due date. Filing belatedly bars the benefit of Section 10AA. However, a belated return does not bar standard deductions (Option A), Section 80C (Option B), or carry forward of losses (Option D). The restriction is targeted at specific incentive-based deductions to enforce timely compliance. Many students mistakenly think all deductions are lost with a belated return; the restriction is narrower and fact-specific to deductions notified as being available only on timely filing.

Q12. The time limit for the Assessing Officer (AO) to issue a notice for detailed Scrutiny Assessment under Section 143(2) is:

  1. Within nine months from the end of the financial year in which the return is furnished.
  2. Before the completion of the assessment.
  3. Within three months from the end of the financial year in which the return of income is furnished.
  4. Within one month from the date of processing the return under Section 143(1).
Show answer & explanation

Correct answer: C. The notice for detailed Scrutiny Assessment must be issued within three months from the end of the F.Y. in which the return is furnished (i.e., within three months from 31st March of that F.Y.). This is a strict statutory deadline, and failure to issue notice within this period generally precludes the AO from proceeding to Section 143(2) assessment—the return is deemed accepted under Section 143(1). This is a critical procedural safeguard. Option A (nine months) and Option B (before completion) are imprecise and do not reflect the statutory strictness. The three-month window is exam-favourite because it tests knowledge of procedural timelines.

Q13. Mr. B, a resident individual, aged 85, files his ROI for A.Y. 2026-27, opting out of the default tax regime. His gross total income is ₹ 5,10,000 (before Section 80C deduction). The basic exemption limit applicable to him is ₹ 5,00,000. Is he mandatorily required to file an ROI?

  1. Yes, because his Gross Total Income exceeds ₹ 5,00,000.
  2. No, because his net Total Income after Chapter VI-A deduction may be below ₹ 5,00,000.
  3. Yes, because his Gross Total Income exceeds ₹ 2,50,000.
  4. No, as resident individuals of age 80 years or more are not mandatorily required to file a return.
Show answer & explanation

Correct answer: A. The filing obligation is determined by comparing GTI (Gross Total Income) against the applicable basic exemption limit, not by T.I. after deductions. Mr. B's GTI of ₹5,10,000 exceeds his exemption limit of ₹5,00,000, so he is mandatorily required to file. The fact that he may later reduce T.I. below the exemption limit through deductions (Section 80C, etc.) does not relieve the filing requirement. Option D is a false trap: there is no blanket exemption for individuals aged 80+; the exemption limit is higher for that age group, but if GTI exceeds it, filing is still mandatory. This question tests the critical distinction between GTI and T.I. in the filing context.

Q14. M/s XYZ LLP is being wound up. Who is the authorised person to verify the firm's Return of Income (ROI)?

  1. Any designated partner of the LLP.
  2. The managing partner.
  3. The liquidator.
  4. The principal officer.
Show answer & explanation

Correct answer: C. When an LLP is being wound up or dissolved, it has no ongoing management authority vested in the partners. The liquidator (or designated representative in the winding-up process) becomes the authorised person to file and verify returns on behalf of the LLP. This ensures that the entity's final tax affairs are properly documented and settled. In normal circumstances, a designated partner would verify (Option A); however, the liquidator's authority supersedes during dissolution. This is a scenario-specific exam question testing knowledge of special circumstances beyond routine business.

Q15. An assessee who has furnished an earlier return (original/belated/revised
