Section 3 of the Indian Stamp Act, 1899 is the charging provision, but it charges nothing on its own — it merely says that the listed instruments shall be chargeable "with duty of the amount indicated in that Schedule". The Schedule is therefore the operative heart of the statute: it is the tariff table that converts the abstract liability created by Section 3 into a precise, article-numbered figure. Schedule I enumerates roughly sixty-five descriptions of instruments — from an Acknowledgement of debt (Article 1) to a Transfer of shares (Article 62) — each carrying either a fixed duty or an ad valorem rate. This article works through the architecture of the Schedule, the most litigated articles, and the two interpretive keys — Sections 5 and 6 — that decide how much an instrument straddling several articles must bear. For the framing rules behind it, read alongside our notes on liability of instruments to duty and the broader Indian Stamp Act hub.
The Schedule as the Statute's Tariff Table
The Indian Stamp Act is, in form, a fiscal statute, and like every fiscal statute it separates the charge from the rate. Section 3 imposes the charge: subject to exemptions, every instrument mentioned in Schedule I, if executed in India (or, if executed out of India, relating to property in India and received in India), "shall be chargeable with duty of the amount indicated in that Schedule as the proper duty therefor". Without the Schedule, Section 3 is a frame with no picture. The Schedule supplies the rate — sometimes a flat figure, more often an ad valorem percentage geared to the consideration, value or amount secured by the instrument.
Schedule I as enacted by Parliament applies in its original form only to instruments falling within the Union List — chiefly bills of exchange, promissory notes, cheques, bills of lading, letters of credit, policies of insurance, transfers of shares, debentures, proxies and receipts (Entry 91, List I). For instruments in the Concurrent field — conveyances, leases, mortgages, partitions, settlements, gifts and the like under Entry 44 of List III read with Entry 63 of List II — each State has substituted its own rates, usually by inserting a Schedule I-A. The article numbering, however, has remained broadly uniform across States, so that "Article 23" almost everywhere means Conveyance and "Article 35" means Lease. This uniformity of nomenclature, coupled with divergence of rate, is the single most important practical feature of the Schedule. For the underlying scheme of what is and is not chargeable, see our note on liability of instruments to duty.
How to Read a Schedule Entry
Each entry in the Schedule has a recurring grammar. The left column gives the description of instrument — the legal category the document must answer to; the right column gives the proper duty. The duty is expressed in one of three ways: a fixed sum (for example, the small fixed duty on an Affidavit under Article 4 or an Acknowledgement under Article 1); an ad valorem figure stated as so much per unit of value (the classic "per five hundred rupees or part thereof" formula in the Conveyance article); or a duty borrowed by reference from another article (a Lease in perpetuity, for instance, is charged as a Conveyance; a Mortgage with possession is charged as a Conveyance on the secured amount).
Two structural devices recur throughout. First, many articles carry their own Exemptions — clauses that withdraw specified instruments from the charge altogether (for example, an agreement for the sale of goods or merchandise is exempt under Article 5). Second, the description is governed by the definitions in Section 2: the word "Conveyance", "Lease", "Bond", "Mortgage-deed" or "Instrument of partition" in the Schedule carries the meaning the definition clause assigns it, not its loose commercial sense. The classification exercise is therefore always a two-step one — first fix the legal character of the document under Section 2, then locate the matching article in the Schedule.
Classification: Substance Over Nomenclature
The cardinal rule of classification is that the Schedule charges the instrument according to its true legal character, not according to the label the parties have put on it. A document headed "Agreement to Sell" may in law be a Conveyance; a deed called a "Power of Attorney" coupled with consideration and possession may operate as a transfer. The Collector and the court look to the recitals, the operative clause and the legal effect, not to the heading.
This principle drove the Supreme Court's intervention in Suraj Lamp & Industries (P) Ltd. v. State of Haryana, (2012) 1 SCC 656. There the Court confronted the widespread "SA/GPA/WILL" practice — transferring immovable property through a sale agreement, a general power of attorney and a will rather than a registered sale deed, precisely to escape the heavier Conveyance duty under Article 23 and registration charges. The Court held that such a combination does not convey title; immovable property can be transferred only by a registered deed of conveyance, and the SA/GPA/WILL device, being designed to evade stamp duty, registration and capital gains tax and to launder unaccounted money, could not be recognised as conveying any title or interest. Though decided primarily under the Transfer of Property and Registration Acts, the ruling is squarely a stamp-duty decision in effect: it shut down a route engineered to avoid the Conveyance article of the Schedule.
Article 23 — Conveyance and the Deemed-Conveyance Rule
Article 23, Conveyance, is the busiest entry in the Schedule and the one that yields the most revenue. "Conveyance" is defined in Section 2(10) to include every instrument by which property — movable or immovable — is transferred inter vivos and which is not otherwise specifically provided for. The duty is ad valorem on the consideration or market value, whichever the State scheme prescribes, and it is invariably the highest tariff in the Schedule, which is exactly why so much classification litigation is about keeping a document out of Article 23.
The most consequential development around this article is the deemed conveyance of an agreement to sell coupled with possession. In Veena Hasmukh Jain v. State of Maharashtra, (1999) 5 SCC 725, the Supreme Court upheld the levy of conveyance duty on an agreement for sale of a flat where the explanation to the conveyance article (Article 25 of the Bombay/Maharashtra Schedule, the State analogue of Article 23) deemed such an agreement — where possession is or is agreed to be delivered — to be a conveyance. The Court reiterated that stamp duty is levied on the instrument and not on the transaction, so an agreement that has the substance of a transfer is taxed as one. The same logic was applied recently in Vayyaeti Srinivasarao v. Gaineedi Jagajyothi (2026), where the Court read the State explanation to mean that an agreement to sell attracts conveyance duty only where possession is in fact acquired pursuant to it. The lesson for the Schedule is that the boundary between Article 5 (Agreement) and Article 23 (Conveyance) is fixed not by the title of the deed but by whether it carries the substance of a transfer, typically signalled by delivery of possession.
Article 35 — Lease, Premium and the Rent Multiple
Article 35, Lease, illustrates how a single article fractures into sub-categories driven by the commercial structure of the document. "Lease" is defined in Section 2(16) to include not only a lease of immovable property but also a kabuliyat, an undertaking to cultivate or occupy, and any agreement to lease. The duty under Article 35 turns on three variables: the term of the lease, whether the lessee pays a premium (a lump sum) in addition to or instead of rent, and whether an advance is paid. A lease reserving rent is charged by reference to the multiple of average annual rent appropriate to the term; a lease in perpetuity or for a term exceeding the prescribed long period is charged as a Conveyance; and where a premium or advance is paid, additional conveyance-rate duty is levied on that sum as if it were consideration for a sale.
The practical significance is that draftsmen cannot dilute duty by recharacterising a long-term transfer as a "lease". Where the substance is a permanent alienation dressed up as a lease, the Schedule's own cross-reference to the conveyance rate pulls the duty back up. The interaction between Article 35 and the time at which the lease must be stamped is dealt with in our note on the time of stamping.
Articles 40 and 45 — Mortgage-Deed and Partition
Article 40, Mortgage-deed, again splits according to substance. A mortgage-deed under which possession of the property is given or agreed to be given is charged as a Conveyance on the amount secured — the rationale being that a possessory mortgage transfers a substantial interest. A mortgage where possession is not given, and a mortgage executed merely as collateral or auxiliary security, attract the lighter Bond rate. The classification thus reflects the economic reality: the closer the mortgage comes to a transfer of enjoyment, the closer its duty comes to conveyance duty.
Article 45, Instrument of partition, charges an instrument by which co-owners divide property held jointly. The duty is computed by reference to the Bond rate on the value of the separated share of the largest co-sharer, with concessional treatment where the partition merely gives effect to a prior agreement or to an order of court or revenue authority. The definition in Section 2(15) is wide enough to catch a final partition decree and an award effecting partition, so parties cannot escape Article 45 by routing the division through an instrument with a different name. These borrowed-rate articles — lease-as-conveyance, possessory-mortgage-as-conveyance, partition-as-bond — show how the Schedule economises on tariff entries by cross-referring rather than re-stating rates.
Article 48 — Power of Attorney and the Benthall Principle
Article 48, Power of Attorney, scales its duty by the number of persons authorised and the number and nature of the acts authorised — a single act of registration at the bottom, a power authorising a person to sell immovable property (often charged as a Conveyance where consideration has passed) at the top. It is the article that produced the Supreme Court's classic exposition of how the Schedule interacts with the framing rules in The Member, Board of Revenue v. Arthur Paul Benthall, AIR 1956 SC 35, (1955) 2 SCR 842.
Benthall had executed a single power of attorney in which he conferred authority on his attorney in several distinct capacities — individually, as executor of one estate, as trustee of another, as a director, and so on. The question was whether this single sheet of paper was chargeable once, or as many times as there were capacities. Venkatarama Aiyar J., for the majority, drew a careful distinction between the operative words of three sections: "transaction" in Section 4, "matter" in Section 5, and "description" in Section 6. He held that the powers, relating to unconnected estates and capacities, were "distinct matters" within Section 5, so the instrument bore the aggregate of the duties that separate powers would have borne. Benthall remains the leading authority on the meaning of "distinct matters" and is the natural bridge from the Schedule's articles to the framing rules discussed next.
Sections 5 and 6 — When an Instrument Touches Several Articles
The Schedule does not operate in isolation; two charging-chapter provisions tell us how to apply it when a document does not fit neatly into one box. Section 5 governs instruments relating to several distinct matters: such an instrument is chargeable with the aggregate of the duties that separate instruments, each dealing with one of the matters, would have attracted. Section 6 governs an instrument so framed as to come within two or more descriptions in the Schedule where the duties are different: it is chargeable only with the highest of those duties.
The distinction is subtle but decisive. Section 5 deals with several separate things bundled into one paper — there, the State adds up. Section 6 deals with one transaction that happens to answer to more than one description in the Schedule — there, the State takes the highest and no more, because the same transaction is not taxed twice merely for fitting two labels. Benthall is the locus classicus for both, holding that "matter" in Section 5 is wider than "description" in Section 6, and that one must first ask whether there are genuinely distinct matters (Section 5) before asking whether a single matter answers to several descriptions (Section 6). Section 6 also carries a proviso protecting a counterpart or duplicate of an already-duly-stamped instrument from bearing more than a nominal duty.
Ad Valorem Duty and the Valuation Problem
Where the Schedule fixes duty ad valorem, the figure that goes into the formula becomes critical, and States have responded to systematic under-statement of consideration by enacting minimum-value ("circle rate" or "ready reckoner") machinery and by amending Section 47-A-type provisions allowing the registering officer to refer an under-valued instrument to the Collector for determination of true market value. The Schedule's ad valorem articles — Conveyance, Settlement, Gift, possessory Mortgage and premium Lease — are the ones that feed this valuation machinery.
The constitutional limit is that stamp duty is a tax on the instrument, not on the transaction or the title it evidences, a point repeatedly stressed from Veena Hasmukh Jain onwards. The valuation exercise therefore fixes the value of what the instrument purports to transfer at the moment of execution; subsequent rises or falls in value are irrelevant. The interplay between the Schedule's ad valorem rate and the adjudication of value is taken up in detail in our note on determination and adjudication of stamp duty.
The Schedule and the Sanction: Sections 33 to 35
An article in the Schedule fixes the proper duty; the teeth that enforce it lie in Sections 33 to 35. By Section 35, an instrument not duly stamped — that is, not stamped to the amount the Schedule requires for its description — "shall not be admitted in evidence for any purpose" and shall not be acted upon, registered or authenticated by any person having authority to receive evidence, unless the deficient duty and a penalty are paid. The classic statement is Hindustan Steel Ltd. v. Dilip Construction Co., (1969) 1 SCC 597, AIR 1969 SC 1238, where the Supreme Court explained that the object of the Act is purely to secure revenue, not to arm a litigant with a technical weapon; once the deficiency and penalty are paid, the instrument becomes admissible, and Section 36 then bars any later objection to its admission.
The bar is keyed to the original instrument. In Hariom Agrawal v. Prakash Chand Malviya, (2008) 5 SCC 479, the Court held that the impounding and penalty machinery operates only on the "instrument" within Section 2(14) — the original document — and a copy or photocopy is not an instrument capable of being impounded or validated by payment of duty. The correct figure for that duty is, of course, read off the relevant article of the Schedule. The Schedule thus sits at the centre of the enforcement chain: it sets the benchmark against which "duly stamped" is measured.
The Schedule, Admissibility and Arbitration Agreements
The admissibility consequence of an under-stamped instrument took a dramatic turn in the arbitration context. After a series of conflicting decisions — SMS Tea Estates (2011) and the five-judge ruling in N.N. Global Mercantile (2023) had treated an unstamped agreement containing an arbitration clause as unenforceable — a seven-judge Bench in In Re: Interplay between Arbitration Agreements under the Arbitration and Conciliation Act, 1996 and the Indian Stamp Act, 1899 (decided 13 December 2023) settled the law. The Court held that non-stamping or insufficient stamping is a curable defect that renders an instrument inadmissible but not void; an arbitration agreement in an unstamped contract remains enforceable, and the stamping objection is to be decided by the arbitral tribunal, not at the reference stage.
For the Schedule, the significance is doctrinal: the ruling reaffirms that the duty fixed by the relevant article and the admissibility bar in Section 35 go to the evidentiary status of the instrument, a defect that payment of the scheduled duty and penalty cures, rather than to the substantive validity of the underlying bargain. The Schedule sets the price of admissibility; it does not invalidate the transaction.
Exemptions Within and Across the Schedule
The Schedule is not a pure tariff; it is studded with Exemptions. Some are article-specific — Article 5 exempts an agreement for the sale of goods or merchandise; Article 4 exempts affidavits filed in court or made for certain official purposes; the receipt and acknowledgement articles exempt small-value and specified transactions. Others operate Schedule-wide through the general exemptions in Section 3 itself and through notifications under Section 9, by which Government may remit or reduce duty in the public interest, often to promote particular classes of transaction such as loans to weaker sections or instruments executed by or in favour of Government.
Because an exemption withdraws an instrument from charge entirely, exemptions are construed against the assessee and in favour of the revenue, consistently with the general rule that a fiscal exemption must be plainly established. The presence or absence of an exemption is therefore part of the classification exercise: it is not enough to find the matching article; one must also check whether the instrument falls within an exemption appended to that article or granted by general notification.
Federal Variation: Schedule I, I-A and I-B
The single most common source of error in practice is treating the central Schedule as universally applicable. It is not. For instruments within the Union's exclusive competence — promissory notes, bills of exchange, cheques, transfers of shares and debentures, bills of lading, letters of credit, policies of insurance, proxies and receipts — the rates in the central Schedule I apply uniformly across India. For instruments in the Concurrent or State field — conveyances, leases, mortgages, gifts, settlements, partitions, bonds, agreements and powers of attorney — the operative rates are those in the State's substituted Schedule I-A (and, in some States, I-B for particular classes).
The result is that the same article number can carry very different duty in different States, and the same conveyance attracts Maharashtra rates in Mumbai and Karnataka rates in Bengaluru. The article-wise structure of the Schedule is national; the figures in the duty column are, for Concurrent-field instruments, State-specific. Any precise computation must therefore begin by identifying the State whose law governs and reading that State's Schedule I-A against the article identified. For the framework that allocates which law governs which instrument, see our note on liability of instruments to duty and the subject hub.
Frequently asked questions
What exactly is the Schedule to the Indian Stamp Act and why does it matter?
Schedule I is the tariff table that fixes the duty for each chargeable instrument. Section 3 creates the liability but charges only "the amount indicated in that Schedule", so the Schedule supplies the actual rate — fixed or ad valorem — for each of the roughly sixty-five article-numbered descriptions, from Acknowledgement (Article 1) to Transfer (Article 62).
If a document falls under two different articles, which duty applies?
Section 6 answers this: an instrument framed so as to come within two or more descriptions in the Schedule with different duties is chargeable only with the highest of those duties, not the sum. This is distinct from Section 5, which adds duties together where the instrument relates to several genuinely distinct matters, as explained in Member, Board of Revenue v. Arthur Paul Benthall.
When is an agreement to sell taxed as a conveyance under Article 23?
Where the State's conveyance article contains an explanation deeming an agreement to sell coupled with delivery of possession to be a conveyance. In Veena Hasmukh Jain v. State of Maharashtra (1999) the Supreme Court upheld conveyance duty on a flat agreement on this basis, stressing that duty is on the instrument's substance, not its label.
Does the same article number carry the same duty everywhere in India?
Only for Union-List instruments such as bills of exchange, promissory notes, cheques and share transfers, where the central Schedule I applies uniformly. For Concurrent-field instruments — conveyances, leases, mortgages, gifts and the like — each State substitutes its own Schedule I-A, so Article 23 in Maharashtra and Article 23 in Karnataka can carry very different rates.
What happens if an instrument is stamped below the figure the Schedule requires?
Under Section 35 it is inadmissible in evidence and cannot be acted upon until the deficient duty and penalty are paid. Hindustan Steel Ltd. v. Dilip Construction Co. (1969) held the object is to secure revenue, not to defeat claims, so payment cures the defect; and In Re Interplay (2023) confirmed the defect is curable and does not void the underlying contract.
Can a photocopy of an under-stamped document be impounded and validated?
No. In Hariom Agrawal v. Prakash Chand Malviya (2008) the Supreme Court held that the impounding and penalty machinery applies only to the original "instrument" within Section 2(14); a copy or photocopy is not an instrument and cannot be validated by paying duty and penalty on it.
