Is Stamp Duty Payable on a Share for Share Exchange in India (2026)?

Whether stamp duty is payable on a share for share exchange is one of the most commercially consequential, yet frequently misunderstood, questions facing M&A and PE deal teams executing share-swap transactions in India. Under the Indian Stamp Act, 1899 and the post-2020 depository-based collection framework, stamp duty treatment hinges on the type of instrument executed (SPA, SSSA or transfer deed), the route of transfer (off-market physical versus demat), and the state in which the instrument is stamped. The Maharashtra Stamp (Amendment) Bill 2026 has added fresh urgency by revising schedule entries that directly affect subscription and allotment instruments used in share-swap structures.

This guide sets out, in practical terms, who pays, at what rate, on which documents, and what deal teams must do at each stage of a transaction to avoid enforceability gaps, penalties and escrow disputes.

The Short Answer: Is Stamp Duty Payable on a Share for Share Exchange?

Yes, in most cases, stamp duty will be payable, but the incidence and rate depend on how the exchange is structured. Under the Indian Stamp Act, 1899, any instrument that effects or records a transfer of shares for consideration (including non-cash consideration such as shares) is prima facie a chargeable instrument. Section 8A of the Act modifies the position for securities held in dematerialised form by routing the collection obligation through depositories and stock exchanges, but it does not eliminate the underlying charge. Where a share-for-share exchange involves the execution of a share purchase agreement (SPA), a share subscription and shareholders agreement (SSSA), or a share transfer deed, each document may attract separate stamp duty under the applicable state schedule.

The post-2020 consolidated collection framework, operationalised through NSDL and CDSL procedural circulars, shifted the collection mechanism for securities transactions to stock exchanges, clearing corporations and depository participants (DPs). Industry observers expect the Maharashtra 2026 amendments to further clarify the state’s schedule entries for subscription instruments, making it essential for deal teams to track state-level Gazette notifications alongside central rules.

Legal Framework: Central Stamp Law and Depository Rules

The stamp duty on transfer of shares in India is governed primarily by the Indian Stamp Act, 1899, read together with the Depositories Act, 1996 and state stamp legislation. The Indian Stamp Act classifies instruments into categories listed in its Schedule, assigning ad valorem or fixed duty rates to each category. Instruments that evidence or effect the transfer or issue of securities fall under several entries, including those for “conveyance,” “transfer” and, in some state schedules, specific securities entries.

Section 8A of the Indian Stamp Act, Explained

Section 8A, inserted by the Finance Act, 2019 and effective from 1 July 2020, provides that the stamp duty on the transfer of securities dealt with by a depository shall be collected by the depository or, in the case of exchange-traded transactions, by the stock exchange or clearing corporation on behalf of the state government. The critical practical effect is twofold:

• The charge is not removed. Section 8A does not exempt demat transfers from stamp duty. It relocates the collection point from the parties (who would otherwise affix physical stamps or purchase e-stamps) to the intermediary infrastructure, the depository, stock exchange or clearing corporation.
• Off-market transfers remain within scope. Where shares are transferred off-market through a delivery instruction slip (DIS) processed by a DP, the DP collects stamp duty at the rate notified by the relevant state and remits it to the state government through the depository.

For share-for-share exchanges, Section 8A applies to the “transfer” leg, the delivery of existing shares from transferor to acquirer via the depository system. However, the “issue” leg, new shares issued by the acquirer as swap consideration, may attract separate duty under state schedule entries for allotment or issue of securities.

Depositories Act, 1996 and Collection Mechanics

The Depositories Act, 1996 defines the legal framework under which NSDL and CDSL operate as central depositories. Section 8A of the Stamp Act cross-references the Depositories Act definition of “depository” and “securities” to delineate which transactions fall under the depository-based collection regime. NSDL Circular NSDL/POLICY/2020/0085 sets out the detailed procedure and guidelines for collection of stamp duty by depository participants, including the obligation on DPs to debit duty from the transferee’s account at the time a transfer instruction is processed. For off-market share swaps between unlisted companies, a common M&A structure, the DP acting for the transferee collects and remits duty based on the consideration value or market value, whichever the state specifies.

SPA vs SSSA vs Share Transfer Deed: Stamp Duty on a Share Swap

A share-for-share exchange typically involves multiple documents, each of which may independently trigger a stamp duty obligation. Understanding the stamp treatment of each instrument is essential when structuring a stamp duty on share swap transaction.

SPA, Stamp Duty on Share Purchase Agreement

A share purchase agreement records the sale and purchase of existing shares for consideration. Where the consideration is cash, the SPA is a chargeable instrument under the applicable state schedule entry for “agreement” or “conveyance.” Where the consideration is shares (i.e., a share swap), the SPA still evidences a transfer for value and remains prima facie stampable. The quantum of duty depends on the state schedule: some states charge ad valorem duty on the value of the shares transferred; others charge a fixed fee for “agreements” not otherwise specifically provided for.

In practice, the stamp duty on share purchase agreement is calculated by reference to the state where the agreement is first executed. Deal teams should include an explicit stamp allocation clause in the SPA, specifying which party bears the cost and providing for an indemnity if the instrument is subsequently assessed for additional duty.

SSSA, When the Issuer Is Liable

A share subscription and shareholders agreement governs the issue (allotment) of new shares. In a share-for-share exchange, the acquirer issues new shares to the target’s shareholders as swap consideration. Under Section 8A and the post-2020 collection framework, the issuer is typically responsible for paying stamp duty on the issue of securities through the depository. The Maharashtra Stamp (Amendment) Bill 2026 has proposed changes to the schedule entries applicable to subscription and allotment instruments, the likely practical effect of which will be to broaden the base on which ad valorem duty is computed for certain types of share issues. Deal teams executing swaps with a Maharashtra nexus should monitor the official Gazette for the notification date of these amendments.

Transfer Deeds, Physical vs Demat

For unlisted and closely held companies where shares are held in physical form, a share transfer deed (Form SH-4 under the Companies Act, 2013) must be executed and stamped in accordance with the state schedule. NSDL procedural circulars confirm that where shares are subsequently dematerialised, the original physical transfer instrument must already be duly stamped, dematerialisation does not cure an unstamped transfer.

For demat transfers, the delivery instruction slip processed by the DP replaces the physical transfer deed. Stamp duty is collected by the DP at the point of transfer, as per NSDL’s detailed procedural guidelines. The rate applied is the rate notified by the state in which the transferee’s DP is registered.

Who Pays Stamp Duty on Shares, Statute and Market Practice

The question of who pays stamp duty on shares in a share-for-share exchange is governed by a combination of statutory rules and commercial negotiation. The Indian Stamp Act does not always specify a single “payer”, it identifies the instrument as chargeable and makes the person executing the instrument primarily liable. In practice, the allocation is shaped by the collection mechanism and by contractual allocation clauses in the SPA or SSSA.

State Rates and 2026 Updates, Stamp Duty Maharashtra 2026 and Beyond

Stamp duty on the transfer or issue of securities is a state subject under the Indian constitutional framework. While the central amendments introduced by the Finance Act, 2019 capped the rates for securities transactions collected through depositories and stock exchanges, states retain the power to set rates for instruments not falling within the depository collection mechanism, including SPAs, SSSAs and physical transfer deeds executed as ancillary deal documents.

The table below provides an indicative snapshot of stamp duty rates applicable to share transfers and related instruments in high-volume jurisdictions. Deal teams must verify current rates against the relevant state Gazette or stamp department website before closing.

The 0.015% rate referenced above is the uniform rate for transfer of securities (on the sell side) collected through the depository / stock exchange mechanism under the post-2020 central framework. Instruments executed outside the depository mechanism, including SPAs, SSSAs and physical transfer deeds, may attract materially different rates under each state’s stamp schedule. The stamp duty Maharashtra 2026 amendments are particularly significant because Maharashtra is the domicile state of the Bombay Stock Exchange (BSE), NSDL’s registered office, and a large proportion of corporate registered offices, meaning a change to Maharashtra schedule entries has outsized practical impact on Indian M&A transactions.

Common Exemptions, Reliefs and Anti-Avoidance Traps

Deal teams structuring share-for-share exchanges often assume that certain reliefs apply automatically. In practice, the position is more nuanced, and missteps can trigger penalties or unenforceability.

• Section 8A depository relief. As noted above, this provision shifts the collection mechanism, it does not create a blanket exemption. Shares transferred through the depository system still attract duty; it is merely collected by the DP or exchange rather than by the parties directly.
• Corporate reorganisations (schemes of arrangement). Transfers effected under a court-approved or NCLT-approved scheme of arrangement under Sections 230–232 of the Companies Act, 2013 may qualify for reduced or nil stamp duty in certain states. However, not all states extend this relief, and the scope of the exemption varies. Deal teams must verify the specific state notification.
• Gift or nominal consideration transfers. Where shares are transferred as a gift (i.e., without monetary consideration), some state schedules apply a different entry or reduced rate. However, a share-for-share exchange involves consideration (the shares received), so gift relief is unlikely to apply.
• Shares of land-holding companies. Several states treat transfers of shares in companies whose principal asset is immovable property as equivalent to conveyances of the property itself, attracting full conveyance duty. This anti-avoidance provision can substantially increase the stamp cost of a share swap involving an asset-holding company.
• Anti-avoidance flags. Where a share-for-share exchange is structured to avoid or minimise stamp duty, for example, by splitting a single transaction into multiple low-value tranches, state stamp authorities may invoke valuation and adjudication powers under Sections 31 and 33 of the Indian Stamp Act to assess the instrument at its true market value.

Execution Checklist: What to Stamp, When, and How

The following checklist provides a practical roadmap for deal teams executing a stamp duty on share swap transaction. Each stage has specific stamping actions that, if missed, can render instruments inadmissible in evidence or trigger penalties under the Indian Stamp Act.

Pre-Signature

• Draft a stamp allocation clause. Include in the SPA or SSSA an explicit provision allocating stamp duty between the parties. Specify which party bears the cost for each instrument (SPA, SSSA, share transfer deed, share certificates).
• Calculate estimated duty. Obtain a state-wise computation of duty based on the transaction value, the instruments to be executed, and the state(s) where execution will occur. Engage the state stamp office or an authorised e-stamp vendor for a preliminary assessment where the quantum is unclear.
• Consider an escrow holdback. Where the applicable state rate is uncertain (for example, pending publication of the Maharashtra 2026 amendments), build a stamp duty escrow holdback into the closing mechanics. This protects both parties against retrospective assessment.

At Signature

• Stamp the SPA / SSSA before or at the time of execution. Under the Indian Stamp Act, an instrument must be stamped before or at the time of execution to be admissible in evidence. Retrospective stamping is possible in some states but attracts penalties.
• Use e-stamping where available. Most major states now accept e-stamps purchased through the Stock Holding Corporation of India (SHCIL) e-stamp platform. Purchase the e-stamp certificate for the correct denomination and affix it to (or reference it in) the relevant instrument.
• Observe state-specific deadlines. Some states impose a time limit (typically within 30 days of execution for instruments executed outside the state) for stamping. Breach of these deadlines attracts penalty interest.

At Closing

• Obtain evidence of DP / depository stamp collection. For demat transfers, confirm that the DP has collected stamp duty on the transfer instruction and retain the NSDL / CDSL acknowledgement or contract note as evidence of payment.
• Stamp share transfer deeds (physical shares). For any leg involving physical share certificates, ensure that Form SH-4 is duly stamped before submission to the company for registration of the transfer.
• Issue stamped share certificates. New share certificates issued as swap consideration should be stamped as required by the applicable state schedule.
• File stamping evidence with registrar. Where the Companies Act requires filing of documents with the Registrar of Companies (e.g., Form PAS-3 for allotment), ensure that stamped copies of the underlying instruments are available for inspection.

Penalties, Interest and Dispute Resolution

Failure to properly stamp instruments in a share-for-share exchange carries significant legal and commercial consequences under the Indian Stamp Act and state stamp legislation.

• Inadmissibility. Under Section 35 of the Indian Stamp Act, an instrument that is not duly stamped is inadmissible in evidence for any purpose. This can be fatal in contractual disputes where the SPA or SSSA is the primary record of the transaction terms.
• Penalty on late stamping. Most states impose a penalty for instruments stamped after execution, typically a multiple of the deficit duty (commonly up to ten times the unpaid duty) plus interest. The exact penalty varies by state and instrument type.
• Adjudication and impounding. Under Sections 31 and 33, a stamp authority may impound an under-stamped instrument presented in legal proceedings and require payment of the deficit duty plus penalty before releasing it.
• Regularisation. Instruments can be regularised by paying the deficit duty plus applicable penalty to the relevant state collector or sub-registrar. Some states allow voluntary disclosure of under-stamped instruments at reduced penalty rates. Deal teams should engage state stamp counsel promptly if a stamping deficiency is discovered post-closing.

Sample Clause Library

The following clauses are provided as drafting templates. They should be adapted to the specific transaction structure and reviewed by Indian stamp counsel before incorporation into definitive agreements.

• Stamp Allocation Clause. “All stamp duty, registration charges and similar levies payable on or in connection with this Agreement, the Share Transfer Deeds and the Share Certificates shall be borne by the Purchaser. Each Party shall co-operate with the other in minimising the aggregate stamp duty payable on the Transaction Documents to the extent permitted by applicable law.”
• Indemnity and Gross-Up. “The Indemnifying Party shall indemnify, defend and hold harmless the Indemnified Party from and against any deficit stamp duty, penalty, interest or other cost arising from the failure of any Transaction Document to be duly stamped in accordance with applicable law, including any additional duty assessed on adjudication by a state stamp authority.”
• Closing Condition, Stamping Evidence. “The obligation of the Purchaser to complete the Closing shall be conditional upon receipt of satisfactory evidence that each Transaction Document has been duly stamped in accordance with the stamp law of the State of [●], including (where applicable) e-stamp certificates and DP acknowledgements of stamp duty collection.”
