Stamp duty is the single most misunderstood line item in any Indian rental arrangement, and most of the confusion comes from one wrong assumption: that there is a single national rate. There is not. Stamp duty on a rental agreement is a State subject, set by each State under its own stamp legislation, which is why the duty on the same flat differs sharply between Mumbai, Bengaluru and Delhi. If you are signing a lease or a leave and licence in 2026, the question that matters is not "what is the rate in India" but "what is the rate in my State, and on what amount is it calculated". This guide sets out how the duty actually works, State by State, so the agreement you sign holds up and is never impounded.
What stamp duty on a rental agreement really is
Stamp duty is a tax on the instrument, not on the transaction behind it. You pay it to make the written rental agreement a valid, admissible document, and an agreement that has not borne the correct duty is not "illegal" so much as legally weak: it cannot be relied on in court until the shortfall and any penalty are cleared. That distinction matters in practice, because tenants and landlords routinely treat the stamp paper as a formality and discover its importance only when a deposit dispute or an eviction lands in front of a judge.
The amount of duty depends on three things that vary by State: the rate itself, the base it is applied to (annual rent, total rent for the term, rent plus deposit, or a slab), and the minimum floor that applies regardless of how small the rent is. A leave and licence in Maharashtra, a rent agreement in Karnataka and a lease deed in Delhi are stamped under three different schedules with three different logics. Do not assume a rate you saw for one State applies anywhere else. The only safe approach is to read your own State's stamp schedule, which is exactly where most online templates fall silent.
The legal framework: one central Act, many State rates
The structure looks complicated but rests on a simple division of power. The Indian Stamp Act, 1899 is the central legislation, and it expressly allows each State to fix and amend the rates of duty on instruments such as leases and rental agreements. Maharashtra applies Article 36A of the Maharashtra (Bombay) Stamp Act, 1958; Delhi applies Article 35 of Schedule IA of the Indian Stamp Act as adapted for Delhi; Karnataka runs its own Karnataka Stamp Act, 1957. Same parent statute, different children, different numbers. You can read the central Act and its schedule on the official Department of Revenue portal through its reference text of the Indian Stamp Act on dor.gov.in, which is the authoritative starting point before you check your State's amendment.
Registration sits in a separate statute and is where the famous eleven-month habit comes from. Under Section 17 of the Registration Act, 1908, a lease of immovable property from year to year, or for any term exceeding one year, must be registered to be valid; the Transfer of Property Act, 1882 governs the lease itself. A great many residential lettings are therefore kept to eleven months, just under the one-year line, specifically to avoid compulsory registration. That is lawful, but it carries a trap worth naming. An agreement for a term above one year that is left unregistered is inadmissible as evidence, so the saving on registration can cost you the entire document when you most need it. Stamping and registration are two separate obligations, and clearing one does not clear the other.
How the rate works State by State
Maharashtra is the cleanest illustration because its rule is explicit. Duty runs at 0.25 per cent of the total rent for the licence period, and where a non-refundable deposit is paid, the same rate applies to that amount. To close an old loophole where landlords took a large interest-free deposit against a token rent, the State now imputes a notional annual interest of ten per cent on any refundable deposit and charges duty on that imputed interest for each year of the term. So the base is not just the headline rent; it is rent plus a deemed return on the deposit.
Delhi works on a slab tied to the lease term rather than a flat percentage of the whole, with the duty for short leases calculated under the bond article of its schedule and rising for longer terms. Karnataka and Tamil Nadu each apply their own percentages and minimums, with Tamil Nadu commonly assessing on annual rent and Karnataka distinguishing by term and urban or rural location. The practical consequence is that two identical flats, let on identical terms in two States, can attract materially different duty. Always compute on your State's base, not on a national rule of thumb that does not exist. When you draft a lease for a property in one State while living in another, it is the property's State that governs the duty, a point that catches out many first-time landlords who own a flat away from where they work.
Drafting and stamping the agreement on Captain.Legal
The reason a guided document beats a downloaded template here is that the duty logic is built into the drafting rather than left to you to reconstruct afterwards. On Captain.Legal you start from the property type and the State, then enter the rent, the deposit and the term, and the rent and leave-and-licence agreements in the real estate category assemble around those inputs with the clauses Indian property practice expects on deposit, lock-in, maintenance and termination. Because the term you choose drives the registration question, the document flags where an eleven-month licence keeps you below the Section 17 threshold and where a longer lease pulls you into compulsory registration.
You then download the finished agreement in Word and PDF, which is what lets you take it to the stamping or e-registration step without redrafting. The Word file is the working copy you can adjust if a party's details change before signing; the PDF is the clean version you execute. If your matter sits at the boundary between a sale and a letting, the platform's property documents and sale deeds under Indian property law sit in the same section, so you are choosing the right instrument rather than forcing a rental template to do a job it was never built for.
Common mistakes that make a rental agreement fail
The first and most expensive error is treating eleven months as a magic shield. It only avoids compulsory registration; it does nothing about stamp duty, which is still payable, and it does nothing if the real arrangement is plainly long-term and a court looks through the label. The second is under-stamping to save a little: an under-stamped agreement can be impounded by the Collector of Stamps, and the Indian Stamp Act allows a penalty of up to ten times the deficient duty, so the gamble is heavily one-sided. The third is paying duty on the rent alone while ignoring the deposit, which in Maharashtra and several other States forms part of the base through the imputed-interest rule.
A fourth recurring problem is confusing stamping with registration and assuming one cures the other; they are independent, and a long lease needs both. The fifth, common among owners with property outside their home State, is applying the wrong State's rate entirely. Each of these is avoidable at the drafting stage. The discipline is simple: identify the property's State, find the correct article in that State's stamp schedule, compute on the right base including any deemed deposit interest, and decide registration separately on the basis of the term. Get those four right and the agreement does its job; get any one wrong and the document you paid for may not protect you when it counts.
Frequently asked questions
Is a rental agreement valid in India without paying stamp duty?
An agreement that has not borne the correct stamp duty is not outright void, but it is legally weak and, crucially, inadmissible as evidence until the duty and any penalty are paid. If a dispute over rent, deposit or possession reaches a court, an under-stamped or unstamped agreement can be impounded by the Collector of Stamps, who may levy a penalty of up to ten times the deficient duty before the document can be used at all. So while you can technically sign on insufficient stamp paper, you have created a document that will not protect you precisely when you need it. Proper stamping is what turns a private understanding into an enforceable instrument.
In what format can I download my rental agreement?
You download the finished agreement in both Word and PDF. The Word version is the editable working copy, useful if a name, date or figure changes before signing, while the PDF is the clean, fixed version you execute and take for stamping or e-registration. Having both formats matters in practice because the stamping and registration steps differ by State, and you may need to adjust details or produce a print-ready copy at short notice. You can revisit and regenerate the document as your terms settle, then move straight to the stamp-and-register stage without rebuilding the agreement from scratch.
When does a rental agreement have to be registered?
Registration becomes compulsory under Section 17 of the Registration Act, 1908 when the lease runs from year to year or for any term exceeding one year. This is the reason so many residential lettings are capped at eleven months, which keeps them just under the threshold and avoids the registration step. Be careful with the trap, though: an agreement for a term above one year that is left unregistered is inadmissible as evidence, so skipping registration on a long lease can cost you the document entirely. Registration is separate from stamp duty, and a long lease needs both. Maharashtra in particular treats registration of leave and licence agreements as mandatory regardless of the eleven-month habit.
Why is the stamp duty different in Mumbai, Bengaluru and Delhi?
Because stamp duty is a State subject. The central Indian Stamp Act, 1899 sets the framework but expressly lets each State fix and amend its own rates, so Maharashtra, Karnataka and Delhi apply different articles, different percentages and different bases. Maharashtra charges 0.25 per cent of total rent plus duty on the deposit through an imputed-interest rule; Delhi uses a term-linked slab; Karnataka and Tamil Nadu each apply their own figures and minimums. Two identical flats let on identical terms in two States can therefore attract very different duty. This is also why no single "national 2026 rate" exists, and why you should always compute on your own State's schedule.
Does the security deposit affect the stamp duty?
In several States, yes, and Maharashtra is the clearest example. A non-refundable deposit is charged duty at the same rate as the rent, and on a refundable deposit the State imputes a notional annual interest of ten per cent and charges duty on that deemed interest for each year of the term. This rule exists specifically to close an old practice where landlords took a large interest-free deposit against a token rent to shrink the duty. The lesson for drafting is that your stamp-duty base is often rent plus a deemed return on the deposit, not the rent alone, so calculating on rent only will leave you under-stamped.
What happens if my agreement is under-stamped?
It can be impounded. When an under-stamped or unstamped instrument is produced before an authority or a court, the document can be sent to the Collector of Stamps, and the Indian Stamp Act permits a penalty of up to ten times the deficient duty before the agreement can be admitted or acted upon. Courts have consistently held that an insufficiently stamped document is not void but is inadmissible until the shortfall and penalty are cleared. The arithmetic makes under-stamping a poor bet: a small saving at signing can turn into a tenfold penalty later, alongside the delay of getting the instrument validated mid-dispute.
Is an eleven-month rental agreement always exempt from registration?
Not always, and the exemption is narrower than people assume. Keeping a lease to eleven months avoids the compulsory-registration line in Section 17 of the Registration Act, 1908, but it does not remove the stamp-duty obligation, which still applies. Courts also look at the real nature of the arrangement, so an eleven-month label on what is effectively a long-term tenancy may not hold. And some States, Maharashtra among them, treat registration of leave and licence agreements as mandatory irrespective of the eleven-month convention. The safest reading is that eleven months helps with registration in many States but is never a blanket exemption and never touches stamp duty.
Where can I check the exact rate for my State?
Start with the central Indian Stamp Act text on the Department of Revenue portal to understand the framework, then look up your own State's stamp legislation and the specific article that covers leases and licences, since that is where the operative rate and base live. Maharashtra users want Article 36A of the State stamp act, Delhi users Article 35 of Schedule IA as adapted for Delhi, and so on. For the document itself, the employment, business and personal categories on Captain.Legal sit alongside the property templates if your matter spans more than a tenancy, and the contracts drafted for enforceability under the Indian Contract Act 1872 follow the same stamp-aware approach. When in doubt on a figure, confirm against the State portal rather than a generic calculator.
