What Is Stamp Paper? Meaning, Types & Uses in India (2026)

Almost every Indian adult ends up holding a sheet of stamp paper at least once. It happens when a flat is rented, when a business partnership is written down, when an affidavit is needed for a passport, or when a property changes hands. The watermarked sheet feels official, slightly old-fashioned, and faintly intimidating, yet most people sign on it without quite knowing what it is or why the law insists on it.

Stamp paper is the everyday face of a 19th-century tax. It is the physical proof that a legal document has paid the duty the state charges for putting an agreement on record. Get the value or the type wrong and a perfectly genuine contract can be refused by a court or a sub-registrar, so the small sheet carries weight far beyond its printed denomination.

This guide explains what stamp paper is, the forms it takes, the duty behind it, and where the system is heading now that most states have moved to electronic stamping. It is general information on how the system works in India, not legal advice; stamp duty rates and rules are set by each state and change often, so the local sub-registrar or an advocate remains the final word for a specific document.

What is stamp paper?

Stamp paper is government-issued paper that carries a pre-paid stamp duty value, used to make written agreements and legal instruments enforceable. Buying the paper is how a citizen pays stamp duty, a tax levied by the state on documents such as deeds, agreements, and affidavits. The duty is collected under the Indian Stamp Act, 1899, one of the oldest fiscal laws still in daily use across the country.

The logic is simple. The state taxes the act of recording a transaction, and the stamp on the paper is the receipt. Without that paid duty, the document is treated as insufficiently stamped, which can make it inadmissible as evidence until the shortfall and a penalty are paid.

Stamp duty is a State subject under the Constitution, so the rate for the same kind of document differs from one state to another. A rent agreement that costs a few hundred rupees to stamp in Delhi may be calculated as a percentage of rent in Maharashtra or Karnataka. The paper looks similar everywhere, but the duty printed on it follows the rules of the state where the document is executed.

"The Indian Stamp Act, 1899 nowhere prescribes any expiry date for use of a stamp paper." (Supreme Court of India, Thiruvengada Pillai v. Navaneethammal, 2008.)

Stamp duty, stamp paper, and the difference between them

Stamp duty is the tax; stamp paper is one way to pay it. Confusing the two is the most common source of error for first-time buyers. The duty is the legal obligation set by the state on a particular instrument, while the paper, the franking impression, or the e-stamp certificate are simply the instruments through which that obligation is discharged.

There are four practical ways to pay stamp duty in India today. Each leaves a different mark on the document, but all of them satisfy the same legal requirement.

Physical stamp paper

Traditional non-judicial stamp paper is the watermarked sheet sold by licensed stamp vendors. It carries a fixed printed denomination, and the agreement is typed or written on the sheet itself. This is the format most people picture, though it is being phased out in favour of e-stamping in most large states.

Franking

Franking is a stamp impression applied by an authorised bank or agent using a franking machine, against payment of the duty. The document is printed on plain paper first, then taken to the franking centre, where a red or blue stamp confirms the duty paid. Several states use franking alongside or instead of physical sheets.

E-stamping

E-stamping replaces the physical sheet with a computer-generated certificate carrying a unique identification number. It was introduced after the Telgi counterfeit scandal exposed how easily physical stamp paper could be forged, and it is now run nationally by Stock Holding Corporation of India (SHCIL) as the central record-keeping agency. The certificate can be verified online, which makes forgery far harder.

E-court fee and judicial stamps

Court fees are paid through judicial stamp paper or e-court fee certificates, governed by the Court Fees Act, 1870 rather than the Stamp Act. This is a separate channel from the non-judicial stamping used for private agreements, and the two should never be mixed up. The distinction is set out in the guide to judicial vs non-judicial stamp paper.

Judicial vs non-judicial stamp paper

The single most important classification is judicial versus non-judicial, because using the wrong one can invalidate a document. Judicial stamp paper is used only to pay court fees, while non-judicial stamp paper covers private agreements, deeds, and affidavits. They are issued under different laws and are not interchangeable.

Judicial stamp paper, also called court fee stamp paper, is used when filing a suit, an appeal, or certain petitions, and the amount is the court fee fixed under the Court Fees Act, 1870. Non-judicial stamp paper is used for everything outside the courtroom: sale deeds, rent agreements, powers of attorney, affidavits, loan and mortgage documents, and partnership deeds, all under the Indian Stamp Act, 1899.

For ordinary readers, non-judicial stamp paper is the relevant one almost all the time. A rent agreement, a business contract, or an affidavit for a bank uses non-judicial paper, never judicial. Picking up court fee stamps for a rental contract is a frequent mistake that gets documents rejected at the registration counter.

Common uses of stamp paper

Non-judicial stamp paper appears in dozens of routine transactions, and the required value rises with the legal and financial weight of the document. Some instruments need only a token denomination, while a property sale deed can attract duty running into lakhs because it is charged as a percentage of the property value.

Rent and lease agreements

Rent agreements are the most common reason ordinary people buy stamp paper, and most are written for 11 months to stay below the registration threshold. Under the Registration Act, 1908, a lease of 12 months or more must be registered with the sub-registrar, so the 11-month term is a deliberate way to keep the agreement on stamp paper without compulsory registration. The value, the 11-month rule, and the calculation are covered in the guide to stamp paper for rent agreements.

Affidavits and declarations

Affidavits for passports, name changes, address proof, and bank formalities are sworn on low-value non-judicial stamp paper, typically Rs 10 to Rs 100. The affidavit is then attested by a notary or an oath commissioner. Banks, schools, and government offices ask for these constantly, which keeps small-denomination stamp paper in steady demand.

Business and commercial agreements

Partnership deeds, loan agreements, powers of attorney, and vendor contracts are executed on non-judicial stamp paper as a condition of enforceability. A new firm registering for GST registration or formalising a partnership will need a properly stamped deed, and a business being set up through the steps in the guide to registering a business in India will encounter stamp duty at several points.

Property transactions

Sale deeds and conveyance documents carry the heaviest stamp duty, calculated as a percentage of the property's market or circle-rate value. Rates commonly run between 4% and 7% of the property value depending on the state and the buyer's category, which is why stamp duty is a major line item in any home purchase. These are always registered, not merely stamped.

Stamp paper denominations and prices

Non-judicial stamp paper is sold in a fixed ladder of denominations, from Rs 5 up to Rs 25,000. Commonly available values include Rs 5, Rs 10, Rs 20, Rs 50, Rs 100, Rs 500, Rs 1,000, Rs 5,000, Rs 10,000, Rs 15,000, Rs 20,000, and Rs 25,000. The buyer chooses the denomination that matches the duty payable on the specific document, as set out in the guide to stamp paper denominations.

The printed value is the stamp duty, not a separate fee. When the duty owed is larger than the highest available sheet, multiple stamp papers are combined or, more commonly today, a single e-stamp certificate is issued for the exact amount. E-stamping removes the old problem of stacking several physical sheets to reach a high duty figure.

Choosing the right value matters because under-stamping is penalised. A document stamped below the required duty can be impounded and admitted only after the deficit plus a penalty is paid, and the penalty can be several times the shortfall. When in doubt, buyers confirm the correct denomination with the sub-registrar's office or an advocate before executing the document.

Does stamp paper expire?

Stamp paper does not expire for use, a point the Supreme Court settled in 2008. In Thiruvengada Pillai v. Navaneethammal, the court held that the Indian Stamp Act prescribes no expiry date for using a stamp paper, and that an old sheet remains valid for executing a document. The widely repeated idea that stamp paper is void after six months is a misreading of the law.

The six-month period actually comes from Section 54 of the Indian Stamp Act, and it governs refunds, not validity. A person holding an unused, unspoiled stamp paper may surrender it to the Collector for a refund of its value, provided it was bought within the previous six months. That window applies only to getting money back, never to whether the paper can still be written on.

"The stipulation of the period of six months prescribed in section 54 is only for the purpose of seeking refund of the value of the unused stamp paper, and not for use of the stamp paper." (Supreme Court of India, Thiruvengada Pillai v. Navaneethammal, 2008.)

In practice, sub-registrars and counterparties often prefer freshly issued stamp paper or a recent e-stamp certificate to avoid disputes, even though an older sheet is legally usable. For e-stamp certificates, states may set their own usage timelines, so a buyer relying on an old certificate should check the rule in their state.

The shift to e-stamping

E-stamping is now the default in most major Indian states, and it exists largely because physical stamp paper proved too easy to counterfeit. The Telgi scam, a counterfeit stamp paper racket valued at over Rs 30,000 crore that unravelled in 2003, pushed governments toward a tamper-resistant electronic system. SHCIL was appointed the Central Record Keeping Agency, and e-stamp certificates carry a unique number that can be verified online.

The benefits are concrete. An e-stamp certificate is generated for the exact duty amount, cannot be backdated, and can be checked on the SHCIL portal or a state portal within seconds, which removes the forgery risk that plagued the old paper. The full process of generating one is covered in the guide to buying e-stamp paper online. States including Karnataka, Maharashtra, Delhi, Gujarat, Tamil Nadu, Rajasthan, Uttar Pradesh, Andhra Pradesh, and Telangana have operationalised e-stamping, while some others continue with physical paper or franking.

Availability still varies. According to e-governance records, a number of north-eastern states and a few others continue to rely mainly on physical stamp paper, so the right method depends on where the document is being executed. The direction of travel is clear: the physical watermarked sheet is slowly giving way to the verifiable digital certificate.

How to buy stamp paper the right way

The safe route is to buy through an authorised channel and match the duty to the document. Buying from a licensed stamp vendor, an authorised bank for franking, or the SHCIL e-stamp portal protects the buyer from counterfeit paper and from the penalties that follow under-stamping. Stamp paper bought from unauthorised sellers carries a real risk of being fake.

A simple checklist helps. Confirm whether the document needs judicial or non-judicial stamping, check the correct duty for that instrument in the relevant state, choose an authorised purchase channel, and keep the receipt or certificate number for verification. For agreements that must also be registered, the stamping is only the first step before the visit to the sub-registrar.

Because duty rates and the choice between physical paper, franking, and e-stamping differ by state, the final figure should always be confirmed locally. The state revenue or registration department portal and the sub-registrar's office hold the authoritative rate for any given document.

Looking ahead

Stamp paper is in the middle of a quiet transition from a 19th-century watermarked sheet to a verifiable digital certificate. The legal principle behind it, that the state taxes the recording of an agreement, is unchanged since 1899, but the mechanism is modernising fast as more states adopt SHCIL e-stamping and integrate it with online property registration.

For citizens and businesses, the practical takeaway is steady: the duty is real, the type and value matter, and the cheapest way to lose a legal advantage is to under-stamp or use the wrong paper. As e-stamping spreads, the process is getting harder to forge and easier to verify, which strengthens the very thing stamp paper was always meant to provide, namely trust that a written agreement will hold up when it is tested.
