Section 423 Interest for defaults in furnishing return of income.

Income-tax Act, 2025

At a Glance

Document compared: Section 423 of the Income-tax Act, 2025 (as appearing in the enacted Act) and Clause 423 of the Income Tax Bill, 2025 (Old Version) (the Bill text supplied). Both texts deal with interest for defaults in furnishing return of income. The provisions affect taxpayers required to furnish returns, and the income-tax department in calculating and demanding interest. Effective date or decision date: Not stated in the document.

Background & Scope

Statutory hook: Clause 423 in the Income Tax Bill, 2025 - Old Version (hereinafter "Clause 423 (Bill)"). Subject matter: interest chargeable for defaults in furnishing return of income. Coverage: outlines when simple interest at the rate implicit in the formula I = 1% x A x T becomes payable, defines the starting and ending dates for computation across specified circumstances, prescribes treatment where post-assessment orders alter tax, and defines components included in "tax paid". Definitions or explanations provided in the text: limited to the formula and the Table; the Bill supplies a definition of "tax paid" in sub-section (4)(d) with enumerated items (i)-(vii). No separate definitions section is provided.

Statutory Provision Mode

Text & Scope

Clause 423 imposes simple interest for defaults in furnishing a return of income. The interest is computed by the formula I = 1% x A x T, where A is the "amount of tax on which interest is payable" (as specified in sub-section (2)) and T is the number of months comprised in the period commencing on the day after the "starting date" and ending on the "ending date" specified in the Table. Sub-section (2) contains a Table that maps specific circumstances to starting date, ending date and the tax base (A) for interest computation. The Table covers four scenarios: (1) return furnished u/s 263(1), (4) or (6) or in response to a notice u/s 268(1) after the due date; (2) no return furnished under the said sections; (3) return required by a notice under an unspecified section issued after certain determinations and furnished late; and (4) where such a notice requires a return and no return is furnished. Sub-section (3) deals with the consequence of orders (under a list of sections) that increase or reduce the tax base for interest, prescribing issuance of notice of demand in prescribed form where interest increases, and refund of excess interest where interest is reduced. Sub-section (4) contains qualifying notes, including exclusions of additional income-tax u/s 267 from the tax bases, reduction of interest payable by amounts of interest paid u/s 266, and the detailed meaning of "tax paid". Sub-section (5) treats an assessment made for the first time u/s 279 as a "regular assessment" for purposes of the section.

Interpretation

Legislative intent as indicated by the Bill text: to provide a simple, uniform interest formula for late or non-furnishing of returns and to tie the interest computation periods to concrete events (due date, date of furnishing, date of completion of assessment, dates specified in notices). The Table-driven approach indicates an intent to vary the tax base (A) and the start/end dates according to factual circumstances of how and when returns are filed or not filed. The inclusion of a detailed "tax paid" definition shows an intent to net off various prepayments and credits from the tax base when computing interest. The provision for adjustment upon post-assessment orders (sub-section (3)) manifests an intent to align interest levies with the final assessed tax position.

Exceptions/Provisos

Carve-outs or qualifications present in the Bill include:

• Exclusion of additional income-tax u/s 267 from the tax base (4)(a)-(b).
• Reduction of interest payable by interest already paid u/s 266 (4)(c).
• Specific items constituting "tax paid" (4)(d)(i)-(vii), which serve as offsets against the tax base for interest calculation.
• Where an assessment is made for the first time u/s 279, it is to be regarded as a regular assessment (5).

Illustrations

• Example 1: A return filed late in response to a notice u/s 268(1). Starting date is the due date u/s 263(1); ending date is date of furnishing; A is tax on total income as determined u/s 270(1) (if regular assessment not made) or tax determined under regular assessment, reduced by "tax paid". (All other specifics of amounts and dates Not stated in the document.)
• Example 2: No return furnished in response to a notice u/s 268(1). Starting date is due date u/s 263(1); ending date is date of completion of assessment u/s 271; A is tax on total income determined under regular assessment reduced by "tax paid". (Concrete amounts and computation Not stated in the document.)
• Example 3: Return required by a notice (serial number 3) but furnished after expiry of time allowed under such notice. Starting date is the date immediately following the last date of time allowed under such notice (Bill text); ending date is date of furnishing; A is amount by which reassessed tax exceeds earlier tax. (The Bill text contains an omission in the cross-reference to the notice section; specifics Not stated in the document.)

Interplay

The Bill text expressly references multiple other provisions (sections 263, 268, 270, 271, 279, 280, 266, 267, 287, 288, 289, 359, 363, 365(10), 368, 377, 378, 206). Interplay with those provisions is central to determining starting/ending dates, the tax base (A), and credits. The Bill, as supplied, contains at least one omitted cross-reference (a missing section number in the Table at serial number 3) and a differing cross-reference for the tax credit clause (206(13) vs the multi-paragraph references in the Act). These differences create potential interpretive issues and could require reconciliation with the substantive provisions of the referenced sections; however, the content of those referenced sections is Not stated in the document.

Differences between the two provisions and practical impact

• Starting date for notice-required returns (serial numbers 3 and 4): The enacted Section 423 (Act) uses "The last date of time allowed under such notice" as the starting date for serial numbers 3 and 4. The Clause 423 of Bill (Old Version) uses "Date immediately following the last date of time allowed under such notice" (for both serial numbers 3 and 4 in the Bill).
  • Practical impact: shifting the stated starting date by one day will change the counted months (T) in the formula I = 1% x A x T in some cases; whether the difference produces a material change depends on the method of counting months under the section (not further specified in the documents). It can lead to one additional month being counted in some interpretations, thereby increasing interest liability slightly in some cases.
• Row 3 starting date wording: In the Act text, for serial number 3 the Starting date is "The last date of time allowed under such notice." The Bill text, for serial number 3, states "Date immediately following the last date of time allowed under such notice."
  • Practical impact: same as above; potential to alter the period used for interest computation.
• Omissions/typographical differences affecting clarity: The Bill's Table entry for serial number 3 contains an apparent omission - "Where return of income is required by a notice u/s issued after..." (the section number is missing). The Act provides the relevant contextual references (Act shows section 280 in related contexts).
• Practical impact: omission creates ambiguity in the Bill text about which notice provision is referred to; this could cause interpretive uncertainty unless corrected. The Act text does not exhibit that omission in the supplied extract.
• "Tax paid" definition - tax credit cross-references: The Act's clause (4)(d)(vii) defines "tax paid" to include "any tax credit allowed to be set off as per sections 206(1)(m) to (p) and 206(2)(e) to (h)." The Bill (Old Version) substitutes "(vii) any tax credit allowed to be set off as per section 206(13)."
  • Practical impact: this is a substantive difference in cross-references. If the Bill's singular reference is intended to capture the same set of credits, the drafting does not make that clear. Depending on the actual content of section 206 in the statute (not stated in the document), taxpayers may lose (or gain) certain credits being treated as "tax paid" for interest computation. As the document supplied does not state the content of section 206, the practical effect cannot be fully determined from the text alone.
• Form of notice of demand: Sub-section (3)(a) in the Act reads "in such form as may be prescribed"; the Bill reads "in the form as prescribed."
  • Practical impact: stylistic/minor drafting difference; both phrases point to prescribed form, but "such form as may be prescribed" is the more conventional legislative formulation. No clear substantive impact in isolation.
• Other structural/wording differences: Minor variations in punctuation, paragraphing and referential phrases occur across the two texts (for example, use of "the Assessing Officer shall serve on the assessee a notice of demand in such form as may be prescribed specifying the sum payable" vs "shall serve on the assessee a notice of demand in the form as prescribed specifying the sum payable").
  • Practical impact: primarily drafting and clarity; no express substantive change beyond the items noted above based on the supplied texts.

Practical Implications

• Compliance and risk areas: The precise starting date language (whether the last date of time allowed or the day after that date) will affect calculation of months (T) - which could increase or decrease interest by the formula provided. Taxpayers filing in response to notices should be alert to how the start date is to be computed. Where the Bill's cross-references differ (notably to section 206), taxpayers should verify which tax credits count as "tax paid" for interest computations - the Bill text introduces uncertainty. The omission of a section number in serial number 3 may create avoidable disputes until corrected.
• Record-keeping/evidence points: The text makes clear that dates of notices, dates of furnishing of returns, dates of completion of assessments and amounts of tax determined at various stages are determinative items. Parties should maintain contemporaneous records showing notice dates, time allowed under notices, dates of filing, assessments and any payments or credits claimed (details of records to be kept Not stated in the document).

Key Takeaways

• Clause 423 (Bill) applies a simple interest formula I = 1% x A x T for defaults in furnishing returns, tying the interest period to specific starting and ending events listed in a Table.
• There are material drafting differences between the Bill and the enacted Section 423: notably in the exact stated starting dates for notice-driven cases and in the cross-references used to define tax credits included as "tax paid".
• Shifts in starting date wording (last date vs date immediately following) can alter interest months counted and thus interest liability; the Bill language tends to state the day after, potentially increasing periods in some views.
• The Bill text contains an omission (missing section reference in serial number 3 of the Table) creating interpretive ambiguity that requires correction or legislative clarification.
• The Bill lists prescribed mechanisms for adjustment where post-assessment orders alter tax and requires notice of demand or refund accordingly.
• The provision for reduction of interest by interest already paid u/s 266 and the detailed enumeration of items constituting "tax paid" show an intent to prevent double charging and to net prepayments and credits.

Section 423 Interest for defaults in furnishing return of income.

Interest for defaults in furnishing return may accrue from differing start dates, altering the interest period and liabilities. Section 423 charges simple interest for defaults in furnishing returns by applying a formula based on a tax base 'A' and a period 'T', with a Table linking specific filing or non-filing scenarios to starting and ending events for the interest period, reductions of the tax base by a prescribed definition of 'tax paid', and provisions for adjustment (notice of demand or refund) where post-assessment orders change the tax on which interest is calculated.
