Is stamp duty calculated on the agreement value or the Ready Reckoner value?

On whichever is higher. If you negotiate below the Ready Reckoner value, duty is still assessed on the Ready Reckoner figure — the discount reduces your price but not your duty.

Do women pay less stamp duty in Maharashtra?

Yes. Residential property purchased in a woman's name attracts a concession of one percentage point. Confirm how it applies to your specific ownership structure, and check the current resale condition attached to it, before relying on it.

Can stamp duty be included in a home loan?

Generally not. Most lenders fund the property price and treat stamp duty and registration as the buyer's own contribution, payable in cash at registration. Budget for them separately.

Is registration fee part of stamp duty?

No. It is a separate charge at 1% of value with a statutory ceiling, which makes it effectively a fixed amount above a certain price point.

In short

Stamp duty on a Navi Mumbai flat is charged on whichever is higher — the agreement value or the Ready Reckoner value. The headline rate is built from a base duty plus a local body tax and a transport surcharge, and women buyers receive a one percentage point concession on residential purchases. Registration is charged separately at 1% of value, subject to a statutory cap.

Key facts

Levied by: Department of Registration & Stamps, Government of Maharashtra
Charged on: Higher of agreement value or Ready Reckoner value
Rate components: Base duty + local body tax + transport surcharge
Women's concession: 1 percentage point on residential property
Registration fee: 1% of value, subject to a statutory cap
When payable: Before or at execution; registration within 4 months

Stamp duty is the single largest cost on top of a flat's price, and it is the one buyers most often under-budget. It is a state tax on the instrument — the agreement itself — not on the property, which is why it falls due when you sign rather than when you take possession.

This guide explains how the charge is built up, what it is calculated on, and where the concessions apply. It deliberately explains the mechanism rather than leading with a single number, because the components change independently of one another and a rate quoted without its parts goes stale silently.

What stamp duty is actually charged on

This is the part that catches people out. Stamp duty is not charged on what you agreed to pay. It is charged on the higher of two figures: the consideration stated in your agreement, and the Ready Reckoner value of the property as published by the state for that year and that location.

If you negotiate a flat down to below its Ready Reckoner value, the state still assesses duty on the Ready Reckoner figure. The saving is real on the price, but it does not extend to the duty. Buyers negotiating hard in a soft market are the ones most likely to be surprised by this.

Agreement value — the consideration recorded in the agreement for sale.
Ready Reckoner value — the state's published rate for that building, locality and floor, multiplied by the chargeable area.
Duty is assessed on whichever of the two is higher.

How the rate is built up

The figure a broker quotes as "the stamp duty rate" is a total, not a single levy. It is assembled from separate components, each with its own legal basis and each capable of changing on its own.

Components of the headline rate in a municipal corporation area

Component	What it is	Applies to
Base stamp duty	The duty under the Maharashtra Stamp Act on a conveyance	All property transfers
Local body tax	A surcharge levied for the local authority	Municipal corporation areas
Transport surcharge	An additional levy earmarked for transport infrastructure	Notified cities, including the Mumbai metropolitan region
Registration fee	A separate fee under the Registration Act, not part of stamp duty	All registrable instruments

The components are structural and stable. The percentages attached to them are not — confirm the current figures on the IGR Maharashtra portal before you budget.

The concession for women buyers

Maharashtra offers a concession of one percentage point on stamp duty where residential property is purchased in a woman's name. It applies to residential property only — not to commercial premises, and not to plots bought for other purposes.

Two practical conditions matter more than the headline. First, the concession attaches to sole or joint ownership where all purchasers are women; a joint purchase with a male co-owner does not generally attract it. Second, the concession has historically carried a resale restriction, and the terms of that restriction have been amended more than once. Confirm the current position before you structure ownership around it.

Applies to residential property purchased in a woman's name.
Ownership structure matters — verify how a joint purchase is treated.
A resale condition has applied historically; check its current terms.
Structuring ownership purely for the concession is a decision to take with your lawyer, not your broker.

Registration is a separate charge

Registration is not part of stamp duty. It is a distinct fee under the Registration Act, 1908, charged at 1% of the value with a statutory ceiling, which means it is effectively a flat amount on anything above a certain price.

The agreement must be registered within four months of execution. Late registration attracts a penalty, and an unregistered agreement for sale is not admissible as evidence of the transaction — which matters enormously if the project runs into trouble later.

What this means for a Navi Mumbai purchase specifically

Navi Mumbai sits inside a municipal corporation area and inside the notified region for the transport surcharge, so both of those components apply. That places it above the rate you would pay in a rural part of the state, and roughly in line with the rest of the Mumbai metropolitan region.

For a buyer, the practical consequence is a budgeting one: on a Navi Mumbai flat the duty and registration together are a material fraction of the purchase price, payable in cash at registration and not fundable by a home loan in the way the price itself is. It has to be available separately.

Common mistakes

Most of the trouble here is avoidable and comes from the same handful of assumptions.

Budgeting duty on the agreement value when the Ready Reckoner value is higher.
Assuming a home loan covers duty and registration — most lenders fund the price, not the levies.
Assuming the women's concession applies to a jointly-held purchase without checking.
Missing the four-month registration window.
Taking a rate quoted in an article from a previous financial year as current — including this one, after its verification date.
