Most Mumbai buyers budget for the price on the agreement and forget the number the government uses to tax them. That second number is the ready reckoner rate, and from 1 April 2026 it went up again. The revision does not change the price a seller quotes, but it can quietly raise the stamp duty and registration cost you pay on top, because the state charges duty on whichever is higher, the agreement value or the reckoner value.

The short answer. Maharashtra revised its ready reckoner rates from 1 April 2026, reported at around 5 percent on average across the state, with higher revisions of up to 8 to 10 percent in pockets near completed infrastructure such as Metro Line 3, the Coastal Road and the upcoming Navi Mumbai airport. In Mumbai, stamp duty is 6 percent for male buyers, made up of a 5 percent base and a 1 percent metro cess, and 5 percent for female buyers, charged on the higher of the agreement value or the reckoner value. The trade off is blunt: a reckoner increase raises your minimum taxable value even when you negotiate a lower price, so the tax floor can rise while your deal does not.

The figure that matters most is that duty is levied on the higher of the two values. That single rule is why the reckoner revision reaches into your budget regardless of what you and the seller agree.

What is the ready reckoner rate and who sets it?

The ready reckoner rate, also called the annual statement of rates, is the government assessed minimum value of property by locality and building type, published by the state and revised each year. It exists so that stamp duty and registration fee cannot be dodged by declaring an artificially low price. The rates are notified through the Maharashtra registration and stamps department and can be read on IGR Maharashtra. For a buyer, the reckoner is not an abstract table. It is the floor beneath your transaction, the value the state assumes your property is worth unless your agreement value is higher.

How much did the 2026 revision raise rates in Mumbai?

The 2026 to 2027 revision, effective from 1 April 2026, has been reported at roughly 5 percent on average, with sharper increases in localities close to newly completed infrastructure. Areas near Metro Line 3 stations, the Coastal Road and the corridor feeding the Navi Mumbai airport were reported to see revisions running higher, in the region of 8 to 10 percent, because the reckoner is meant to track the market value that new connectivity pushes up. Buyers should treat the exact locality figure as something to confirm on the official reckoner for their specific area, since the average hides wide variation between one node and the next.

How does a reckoner increase change your stamp duty?

Stamp duty in Mumbai is charged as a percentage of the higher of the agreement value or the reckoner value, so when the reckoner rises, the taxable base can rise with it. If your negotiated price sits above the reckoner, the revision may not touch your duty at all, because you are already taxed on the higher agreement value. But if your price is at or below the reckoner, the increase lifts the value on which you are taxed, and your duty goes up even though your deal did not. This is the quiet mechanism buyers miss, and it matters most in softer micro markets where negotiated prices hover near the reckoner floor.

What is the full stamp duty and registration structure in Mumbai?

For property in Mumbai, male buyers pay 6 percent, comprising a 5 percent base stamp duty and a 1 percent metro cess, while female buyers pay 5 percent under the concession the state offers to women owners. On top of that sits the registration fee of 1 percent of the value, subject to the standard cap applied to most residential transactions. So a rough all in figure for transaction charges is around 7 percent for a male buyer and 6 percent for a female buyer, before the smaller incidental costs. The concession makes registering in a woman owner name or joint name with a woman a genuine saving worth weighing against family and tax considerations. We cover the mechanics in detail in our guide to Maharashtra stamp duty and registration charges.

Does the revision affect under construction and resale differently?

The reckoner floor applies to both, but the way it bites differs. In a resale, the reckoner is compared directly to your agreement value, so the revision can lift the taxable base at once. In an under construction purchase, the applicable value and the timing of duty depend on the agreement structure, and buyers near infrastructure that just triggered a higher reckoner revision should check whether the new rate applies to their registration date. Either way, the honest planning move is to compute your duty on the current reckoner for the exact flat, not on last year table, so the number in your budget matches the number at the sub registrar office.

How should buyers plan around the 2026 reckoner?

Build the transaction cost into your budget from the reckoner up, not from the price down. Pull the current reckoner value for the specific building and carpet area, compare it with your agreement value, and calculate duty on the higher figure. If you are buying near Metro Line 3, the Coastal Road or the Navi Mumbai airport corridor, expect the reckoner to have moved more than the citywide average, and confirm the locality figure rather than assuming 5 percent. For the broader connectivity picture that is pushing these pockets up, read our note on the Navi Mumbai airport property impact. The point is to remove the surprise, since the reckoner is public and your duty is arithmetic once you have the right value.

How the 2026 reckoner revision reaches your cost

Seven point checklist for the 2026 reckoner

1. Pull the current ready reckoner value for the exact building, wing and carpet area.
2. Compare it with your agreement value and identify which figure is higher.
3. Calculate stamp duty on the higher figure, not on the price you negotiated.
4. Add the 1 percent metro cess for Mumbai and the registration fee to reach the all in cost.
5. Check whether a woman owner or joint registration lowers your duty to 5 percent.
6. If buying near new infrastructure, confirm the locality revision rather than assuming the average.
7. Confirm which reckoner year applies to your registration date before you commit.

Frequently asked questions

When did the 2026 ready reckoner revision take effect in Maharashtra?

The revised ready reckoner rates for 2026 to 2027 took effect from 1 April 2026. The increase was reported at around 5 percent on average across the state, with higher revisions in localities close to newly completed infrastructure such as Metro Line 3, the Coastal Road and the Navi Mumbai airport corridor.

Is stamp duty charged on the agreement value or the reckoner value?

Stamp duty is charged on whichever is higher, the agreement value or the ready reckoner value. If your negotiated price is above the reckoner, duty is based on the price. If it is at or below the reckoner, duty is based on the reckoner, so a revision can raise your tax even when your deal does not change.

What is the stamp duty rate for a woman buyer in Mumbai?

A female buyer in Mumbai pays 5 percent, against 6 percent for a male buyer, which includes the 1 percent metro cess. Registering in a woman owner name or joint name with a woman can therefore lower the duty, a saving that grows larger as the property value and the reckoner rise.

Does the reckoner revision increase my cost if I negotiated a low price?

It can. Because duty is charged on the higher of the agreement value or the reckoner, a low negotiated price does not shield you if it falls below the revised reckoner. In that case the reckoner becomes your taxable base, so the revision lifts your duty even though your price did not move.
