Stamp Duty on Agreements in India: What Attracts It, Why Timing Matters, and How E-Stamping Works
Stamp duty confuses more Indian businesses than any other contracting rule. Which agreements attract it, why it must be paid before signing, what happens to an unstamped agreement, how e-stamping works state by state, and how it fits with e-signature.
Every Indian business has asked "do we need stamp paper for this?" and received a different answer each time. The rules are simpler than the folklore: duty is charged on instruments listed in a schedule, it must be paid before or at signing, an unstamped instrument cannot be used in evidence until the duty and a penalty are paid, and e-stamping is now the normal way to pay. This guide covers the principles that apply everywhere and flags where states differ. Position as of October 2026.
What is charged
The Indian Stamp Act, 1899 charges duty on "instruments" (documents by which rights or liabilities are created, transferred, limited, extended, extinguished or recorded) listed in its Schedule I; states levy duty on instruments within their competence under their own Acts and schedules (Maharashtra, Karnataka, Gujarat, Rajasthan and others have their own Stamp Acts; many others apply the central Act with state amendments). Commonly charged commercial instruments include agreements or memoranda of agreement, leases and leave and licence agreements, indemnity bonds, powers of attorney, security documents, share transfers and partnership deeds. Whether a particular MSA, NDA or SOW is charged, and at what rate, depends on the article under which the state schedule classifies it. ****
When it must be paid
Section 17 of the central Act: instruments chargeable with duty and executed in India "shall be stamped before or at the time of execution". The timing rule is why e-stamping must be a step before the signature request in any digital workflow.
What happens if it is not
Section 35: an instrument not duly stamped "shall not be admitted in evidence for any purpose" until the duty and the prescribed penalty are paid, with limited exceptions. Section 33 empowers authorities to impound such instruments. The agreement is not void; it is unusable in court until regularised, and the penalty can be a multiple of the duty. For a business, the practical consequence is that the unstamped vendor agreement you relied on cannot be produced in a dispute without first paying up.
Where duty is paid
Duty is attracted by the state in which the instrument is executed; section 19 of the central Act (and state equivalents) can require the difference to be paid when an instrument executed elsewhere is received in a state and relates to property or matters there. For electronically signed agreements where parties sign from different places, state the place of execution in the document and stamp accordingly.
How e-stamping works
Most states now issue stamp duty through electronic systems rather than physical stamp paper:
- SHCIL e-Stamp operates as the central record keeping agency in several states and union territories, issuing e-stamp certificates through authorised collection centres and, for many instruments, online.
- State treasury systems, such as GRAS in Maharashtra (where the 2025 amendment to section 10 of the Maharashtra Stamp Act formalised e-payment with an endorsement or e-stamp certificate) and e-GRAS in Haryana (mandatory statewide since 1 March 2017).
The output in each case is a certificate with a unique number, the amount, the parties and the instrument description, which is attached to the agreement and can be verified online. ****
E-stamp plus e-signature: the sequence
- Classify the template under the state schedule and record the article and rate.
- On intake, capture the place of execution and the values the duty depends on (rent, deposit, consideration, term).
- Generate the e-stamp certificate.
- Attach it as the first page of the execution version.
- Send for electronic signature (Aadhaar eSign or DSC under the IT Act, 2000).
- Store the signed document, the certificate and the audit trail together.
Common mistakes
- Signing first, stamping later (section 17 breach; penalty on regularisation).
- Using one certificate for a batch of separate agreements (duty is per instrument).
- Stamping under the wrong state because the signatories were in different cities.
- Treating a "non-binding MoU" as exempt when it contains chargeable obligations.
- Forgetting that an amendment changing the chargeable terms may itself attract duty.
Where Legatio fits. Legatio carries the stamp article and state in template metadata, places the e-stamp step before signature, attaches the certificate per instrument and files it with the audit trail. Rates and channels are the state's.
