Clause 393 Tax to be deducted at source.

Income Tax Bill, 2025

Introduction

The Indian tax regime has, over the past decade, significantly expanded the scope of tax deduction at source (TDS) and tax collection at source (TCS) to ensure better tax compliance, plug revenue leakages, and create audit trails for high-value transactions. Among the most impactful provisions in this context has been the requirement to deduct TDS on payments made for the purchase of goods, introduced via Section 194Q of the Income-tax Act, 1961, effective from July 1, 2021 vide Finance Act, 2021.

With the tabling of the Income Tax Bill, 2025, a comprehensive re-codification and rationalization of the law is underway. Clause 393(1)[Table: S.No. 8(ii)] of the Bill introduces a provision for TDS on the purchase of goods, which, in substance, seeks to carry forward the legislative intent of Section 194Q, but with certain notable modifications and clarifications. This commentary provides an in-depth analysis of Clause 393(1)[Table: S.No. 8(ii)], examines its objectives, practical implications, and potential interpretational issues, and offers a detailed comparative analysis with the existing Section 194Q of the Income-tax Act, 1961.

Objective and Purpose

The legislative intent behind both Section 194Q and its successor provision in the Income Tax Bill, 2025, is to widen and deepen the tax base by creating a mechanism for tracking large purchases of goods. The rationale is threefold:

  • To ensure that high-value transactions do not escape the tax net, especially in the unorganized sector where the risk of under-reporting is significant.
  • To create a robust audit trail, facilitating the detection of tax evasion and ensuring better compliance.
  • To rationalize the TDS and TCS regime, avoiding duplication and conflicts between multiple provisions, and providing clarity on the precedence of deduction or collection.

The move also aligns with global best practices, where withholding tax mechanisms are used to ensure real-time tax collection and reporting.

Detailed Analysis of Clause 393(1)[Table: S.No. 8(ii)] of the Income Tax Bill, 2025

1. Statutory Text and Structure

Clause 393(1) [Table: S.No. 8(ii)] of the Income Tax Bill, 2025, reads as follows:

Any sum for purchase of any goods.
Payer: Any person, being a buyer.
Rate: 0.1% of such sum exceeding Rs. 50,00,000.
Threshold limit: Rs. 50,00,000.

The provision is accompanied by a crucial Note 1:

The deduction of tax under serial number 8(ii) shall not apply to a transaction on which tax is deductible or collectible under any of the provisions of the Act.

Let us break down and analyze the key elements of this provision.

2. Scope of Application

  • Payer ("Buyer"): The provision applies to "any person, being a buyer." Unlike Section 194Q, which defines "buyer" with reference to turnover exceeding Rs. 10 crore in the preceding financial year, the Bill provision appears, at first glance, to have a broader scope. However, the implementation details and possible subsequent rules or notifications may clarify whether any threshold for the buyer's turnover is intended.
  • Payee ("Seller"): The TDS is to be deducted on payments to a resident seller. This is consistent with the policy of not imposing TDS obligations on cross-border purchase transactions, which are governed by separate provisions.
  • Nature of Transaction: The TDS applies to "any sum for purchase of any goods," indicating a wide coverage, including all movable property that is not money or actionable claims, unless specifically excluded by the Act or rules.

3. Threshold and Rate

  • Threshold: The TDS obligation arises only if the value or aggregate value of purchases from a seller in a financial year exceeds Rs. 50,00,000. This ensures that small and medium transactions are not burdened by compliance costs.
  • Rate: The rate of TDS is set at 0.1% of the sum exceeding Rs. 50,00,000. This is a nominal rate, designed to create an audit trail rather than serve as a significant source of revenue.

4. Timing of Deduction

The TDS is to be deducted at the earlier of:

  • the time of credit of such sum to the account of the payee (seller), or
  • the time of payment, by cash, cheque, draft, or any other mode.

This is consistent with the standard TDS regime, ensuring that the liability to deduct arises irrespective of whether the payment is made or only credited in the books.

5. Exclusionary Provision (Note 1)

A key feature is the exclusionary clause:

The deduction of tax under serial number 8(ii) shall not apply to a transaction on which tax is deductible or collectible under any of the provisions of the Act.

This is significant for preventing overlap and double deduction/collection, particularly with respect to other TDS and TCS provisions, such as Section 206C(1H) (TCS on sale of goods), or TDS on contracts.

6. Other Procedural Aspects

While the main clause provides the substantive obligation, procedural aspects such as return filing, issuance of TDS certificates, and consequences of non-compliance are likely to be governed by general provisions applicable to TDS under the Bill.

Practical Implications

1. Impact on Businesses

  • Compliance Burden: Businesses, especially large buyers, will need to monitor aggregate purchases from each seller to determine when the threshold is crossed. This requires robust accounting systems and regular reconciliation.
  • Cash Flow: Sellers will receive net payments (after TDS), and will need to claim credit for TDS while filing returns. While the rate is low, for high-value transactions, the quantum may not be insignificant.
  • Contractual Negotiations: The TDS regime may necessitate changes in contractual arrangements, especially in cases of price escalation, returns, or discounts, to ensure correct computation of the TDS base.

2. Avoidance of Double Deduction/Collection

The exclusionary clause is vital to avoid situations where both TDS and TCS could have been applied (as was a concern under the Section 194Q/206C(1H) regime). The Bill's provision appears to create a clear hierarchy: if any other TDS/TCS provision applies, Clause 393(1)[8(ii)] will not apply.

3. Administrative and Systemic Adjustments

  • ERP and Accounting Systems: Enterprises will need to configure their ERP or accounting software to track cumulative purchases and trigger TDS deduction at the appropriate time.
  • Vendor Communication: Buyers may need to communicate with vendors regarding TDS deduction, and sellers will need to reconcile TDS credits for advance tax and return filing.

4. Ambiguities and Issues

  • Definition of "Buyer": The Bill provision does not, in its text, specifically define "buyer" with reference to turnover, unlike Section 194Q. This could potentially expand the scope to all buyers unless clarified by rules or notifications.
  • Nature of "Goods": The term "goods" is not defined in the Bill extract. In the absence of a definition, reference may be made to the Sale of Goods Act, 1930, or judicial precedents. Exclusions, such as for securities or actionable claims, may need to be specified to avoid interpretational disputes.
  • Interaction with Other TDS/TCS Provisions: While the exclusionary clause is clear, practical issues may arise in identifying which provision applies first, especially in complex transactions.

Comparative Analysis with Section 194Q of the Income-tax Act, 1961

1. Scope and Applicability

Feature Section 194Q of the Income-tax Act, 1961 Clause 393(1)[Table: S.No. 8(ii)] of the Income Tax Bill, 2025
Applicability (Buyer's Turnover) Buyer with turnover > Rs. 10 crore in preceding FY "Any person, being a buyer" (appears to have no turnover threshold unless otherwise defined)
Rate of TDS 0.1% on sum exceeding Rs. 50 lakh 0.1% on sum exceeding Rs. 50 lakh
Threshold Limit Aggregate value exceeding Rs. 50 lakh per seller per FY Aggregate value exceeding Rs. 50 lakh per seller per FY
Seller's Residency Resident seller Resident seller
Timing of Deduction Credit or payment, whichever is earlier Credit or payment, whichever is earlier
Anti-Overlap Provision Not applicable if TDS/TCS under any other provision (esp. 206C(1H)) Not applicable if TDS/TCS under any other provision of the Act
Definition of "Buyer" Specifically defined; includes turnover threshold Not specifically defined in the Table; may rely on general definitions or notifications
Guidelines for Difficulties CBDT empowered to issue guidelines General provisions for guidance may exist, but not specified in this clause
Overlap with TCS 206C(1H) Explicitly excluded (now omitted as per 2025 amendment) General anti-overlap clause; 206C(1H) omission may be reflected here as well

2. Key Points of Divergence

  • Turnover Threshold for Buyer:
    • Section 194Q: Applies only to buyers with turnover exceeding Rs. 10 crore in the preceding year.
    • Clause 393(1)[8(ii)]: Provision as per the text does not specify such a threshold, potentially broadening the scope to all buyers unless clarified otherwise.
  • Exclusion of TCS u/s 206C(1H):
    • Section 194Q: Not applicable if tax is collectible u/s 206C(1H) (TCS on sale of goods).
    • Clause 393(1)[8(ii)]: Not applicable if tax is deductible or collectible under any provision of the Act, providing a broader exclusion and clearer hierarchy.
  • Guidance and Clarifications:
    • Section 194Q: Empowers CBDT to issue guidelines for removing difficulties, which are binding on tax authorities and taxpayers.
    • Clause 393(1)[8(ii)]: No express provision in the extract; general powers may be exercised under the Bill's framework.
  • Omission of Section 206C(1H) Reference:
    • Section 194Q's exclusion for TCS u/s 206C(1H) has been omitted by the Finance Act, 2025, effective April 1, 2025, aligning with the new Bill's approach of a single exclusion for any TDS/TCS provision.

3. Policy and Compliance Implications

  • Wider Compliance Net: If the Bill's provision is interpreted to apply to all buyers (without a turnover threshold), a much larger number of entities, including small and medium businesses, could be brought within the TDS net, increasing compliance requirements and administrative burden.
  • Clarity on Precedence: The Bill's language brings clarity to the precedence of TDS/TCS, reducing the confusion and disputes that arose under the earlier regime regarding which party (buyer or seller) was to deduct/collect tax in overlapping situations.
  • Potential for Overlap: The comprehensive exclusion for transactions covered by any other TDS/TCS provision reduces, but does not eliminate, the possibility of interpretational disputes, especially in complex supply chains or multi-party transactions.
  • Need for Further Clarification: Absence of a defined "buyer" threshold and the undefined scope of "goods" may necessitate further clarification through rules, notifications, or circulars to avoid overreach and litigation.

4. Judicial and Administrative Guidance

Section 194Q has seen several circulars and FAQs issued by the Central Board of Direct Taxes (CBDT) to address practical difficulties, including issues such as adjustment for purchase returns, treatment of discounts, and interaction with TCS u/s 206C(1H). The Bill's provision, being a successor, will likely inherit these practical issues, and administrative guidance will be essential to ensure smooth implementation.

Conclusion

Clause 393(1)[Table: S.No. 8(ii)] of the Income Tax Bill, 2025, represents a continuation and rationalization of the policy underlying Section 194Q of the Income-tax Act, 1961, with a view to strengthening the TDS regime on the purchase of goods. The provision seeks to create a clear audit trail for high-value transactions, reduce opportunities for tax evasion, and provide clarity on the hierarchy of TDS and TCS obligations.

The most significant divergence from the existing law is the apparent omission of a turnover threshold for buyers in the Bill's text, which could have far-reaching compliance and administrative implications. The exclusionary clause is also broader and more streamlined, potentially reducing confusion and litigation. However, the absence of explicit definitions and the need for practical guidance remain, underscoring the importance of timely administrative clarifications and, where necessary, legislative fine-tuning.

As the new regime is implemented, stakeholders-especially businesses and tax professionals-will need to closely monitor developments, ensure robust compliance systems, and engage with authorities to address interpretational and procedural challenges. The ultimate success of the provision will depend on a balanced approach that achieves the twin objectives of revenue protection and ease of doing business.
