In Bangalore, a rental agreement is often treated as a formality: a template is printed on stamp paper, signed in a hurry on moving day and forgotten. But that document decides how much of your security deposit you get back, how much notice you must give, how much the rent can go up, and whether you can use the address for Aadhaar or your bank. It is worth half an hour of careful reading.

This guide explains how rental agreements work in Bangalore, which clauses to check, what Karnataka's latest Rent Act amendment actually changed, and the tax rules that tenants often miss.

Key points

  • Most Bangalore rentals use an 11-month agreement on Karnataka e-stamp paper. Leases longer than a year must be registered.
  • A registered agreement is stronger proof of address than a notarised one.
  • Read the clauses on the deposit, notice period, lock-in, rent increase and painting charges before you sign.
  • Pay rent and the deposit by bank transfer, and keep receipts.
  • Karnataka's December 2025 amendment replaced jail terms with fines. Despite claims online, it did not cap deposits at two months' rent.

1. Why rental agreements are for 11 months

Under the Registration Act, 1908, a lease for a term of more than one year must be registered at the sub-registrar's office, which involves higher costs and a visit by both parties. A lease of 11 months does not need compulsory registration, so most landlords and tenants choose 11 months and simply renew the agreement each year.

That convenience has a downside: an unregistered agreement is weaker evidence if there is a dispute, and it may not be accepted as proof of address everywhere. For longer stays, a registered agreement is the better choice.

2. E-stamp paper and stamp duty

3. Notarised or registered?

Many Bangalore agreements are simply signed on e-stamp paper, with two witnesses, and sometimes notarised. A notary only attests the signatures. It does not register the agreement.

4. What Karnataka law says in 2026

Residential tenancies in the state are governed by the Karnataka Rent Act, 1999. Among other things, it requires premises to be let under an agreement in writing, and in certain situations requires the landlord and tenant to file a copy of the agreement, or its particulars, with the prescribed authority.

In December 2025, the Karnataka Legislature passed the Karnataka Rent (Amendment) Bill, 2025. As reported by Deccan Herald, it removes imprisonment for minor offences and increases fines. For example, a landlord or tenant who fails to present a copy of the tenancy agreement or particulars as required now faces a fine instead of possible jail, and rental agents who do not register with the government face fines too. During the debate, the Revenue Minister said the government would focus on regulating rents and protecting tenants. That was a statement of intent, not a new rule.

Beware of misinformation. Several websites claim the amendment caps security deposits at two months' rent and makes online registration of every rental agreement compulsory within 60 days. These ideas come from the central government's Model Tenancy Act, a template that states may adopt. We could not find them in the amendment passed by Karnataka or in news reports of it. Before relying on any "new rent rule", check the official text or ask a lawyer.

5. Clauses to check before you sign

Most agreements come from the landlord's or broker's template. Read every clause, and ask for changes before signing, not after.

6. The security deposit

Bangalore is known for high security deposits, often several months' rent, and much higher than in most Indian cities. There is no clearly established legal cap in Karnataka today, so the amount is negotiated between you and the landlord.

Frequently asked questions

Is an 11-month rental agreement legal in Bangalore?

Yes. Leases of up to one year do not need compulsory registration, which is why 11-month agreements on e-stamp paper are the norm. You can still choose to register one, and a registered agreement gives you stronger proof of address and terms.

Is there a limit on the security deposit in Karnataka?

There is no clearly established legal cap today, and the deposit is negotiated. The two-month cap often mentioned online comes from the central Model Tenancy Act and was not part of Karnataka's December 2025 amendment, as far as we could find.

Can I use a notarised rent agreement for an Aadhaar address update?

UIDAI's update form lists a registered rent agreement as proof of address, so a notarised one alone may be rejected. A recent bank statement showing the new address is a common alternative.

Who pays the stamp duty on a rental agreement?

It is a matter of agreement between the landlord and tenant. Tenants usually pay, but you can agree to share it.

Do I need to deduct TDS on rent?

If you are an individual paying more than ₹50,000 a month in rent, yes. Check the current rate and procedure under the Income-tax Act, 2025.
