Two friends bought identical 2 BHK flats on the same floor of the same Mumbai tower in early 2026, at the same price. One paid a little over 6 lakh rupees in stamp duty. The other paid roughly 1 lakh rupees less. The difference was not negotiation or timing. One flat was registered in a woman's sole name, and Maharashtra rewards that with a full 1 percent cut in stamp duty. In a city where flats routinely cross a crore, that 1 percent is real money, and it is only one of several numbers a Mumbai buyer needs to get right before signing.

The short answer. In Mumbai, stamp duty is 6 percent for a male buyer and 5 percent for a female buyer, both figures already including the 1 percent metro cess, plus a 1 percent registration fee capped at 30,000 rupees for property above 30 lakh. It is charged on the higher of your agreement value or the locality Ready Reckoner Rate. The trade off worth planning around: the woman sole owner concession saves 1 percent, but it applies only to residential property held in a woman's sole name, so a joint purchase with a male co-owner is charged at the full male rate.

What are the exact stamp duty and registration rates in Mumbai?

The headline rate depends on who is on the title. A male buyer in Mumbai pays 6 percent stamp duty and a female buyer pays 5 percent, and in both cases the 1 percent metro cess is already baked into that figure. The base stamp duty is 5 percent for men and 4 percent for women, with the metro cess adding the final 1 percent. Registration is charged separately at 1 percent of the value, but it is capped at 30,000 rupees once the property crosses 30 lakh, which is almost every flat in the city. The table lays out what a buyer is actually looking at.

Note that these are Mumbai figures. Elsewhere in Maharashtra the total runs higher, commonly cited near 7 percent for men in Pune, Thane and Nagpur once the local body tax and metro cess are added, so a buyer comparing across the region should not assume the Mumbai number travels with them.

How much does the women buyer concession actually save?

The concession lowers stamp duty by a full percentage point, and on Mumbai prices that adds up quickly. On a 1 crore rupee flat, the male rate of 6 percent is 6 lakh rupees, while the female rate of 5 percent is 5 lakh rupees, a clean 1 lakh rupee saving. There are conditions that matter. The reduced rate applies to residential property registered in a woman's sole name. If the flat is bought jointly with a male co-owner, the standard male rate applies, so the ownership structure has to be decided with this in mind rather than corrected afterwards.

This is a decision to take deliberately and with proper advice, weighing succession, loan eligibility and family circumstances, not just the stamp duty line. It is a genuine saving, but it should fit your overall plan for the home rather than drive it. Because the exact conditions can be updated, confirm the current rules on the official IGR Maharashtra portal or with your lawyer before you structure the purchase around them.

The policy exists to encourage property ownership among women, and it has become a routine part of how many Mumbai families structure a purchase. It does not extend to commercial property and is tied to residential use, so a shop or office in a woman's name will not attract the lower rate. Where it does apply, the saving is immediate, applied at the time of registration rather than as a later refund, which makes it one of the cleaner ways to reduce the cost of buying in the city.

What value is the duty calculated on?

Duty is charged on the higher of two numbers: your agreement value, or the Ready Reckoner Rate for that locality applied to the carpet area of the flat. The Ready Reckoner Rate, sometimes called the ready reckoner or circle rate, is the state's notified minimum value for an area. If your negotiated price is above it, you pay on your price. If the reckoner value works out higher, you pay on that, even if you struck a good deal. This is why two buyers paying the same price in different localities can face different duty, and why the reckoner value is a number to check rather than assume.

Because the reckoner is applied to carpet area, understanding exactly what carpet area your flat carries is not just a RERA formality, it feeds directly into your duty. A larger carpet area at a given reckoner rate means a larger assessed value and a larger bill, so the area figure on your agreement deserves a careful read.

Ready Reckoner Rates are revised by the state from time to time, so the figure that applied last year may not be current. Because a revision changes your duty even when the percentage stays the same, treat the reckoner value as a number to confirm close to your purchase date rather than one to carry over from an older estimate you were given.

How do I compute and pay Mumbai stamp duty officially?

Use the government's own tools rather than a broker's estimate. The IGR Maharashtra portal publishes Ready Reckoner Rates and provides a stamp duty calculator, with payment handled through the linked GRAS system. Pull the reckoner rate for your locality, apply it to your carpet area, compare that with your agreement value, and compute duty on the higher figure at the rate for your ownership structure. The seven steps below keep it orderly.

1. Open the official IGR Maharashtra portal and find the stamp duty calculator.
2. Look up the Ready Reckoner Rate for your locality and property type.
3. Multiply the reckoner rate by your flat's carpet area to get the assessed value.
4. Compare that assessed value with the price in your agreement.
5. Take the higher of the two figures as your base.
6. Apply 6 percent for a male buyer or 5 percent for a sole female buyer, then add 1 percent registration up to the 30,000 rupee cap.
7. Pay through the linked GRAS portal and keep the challan with your records.

Running this before you sign turns a large unknown into a fixed line in your budget. It also pairs with the wider set of charges that catch buyers out, which we lay out in our guide to the true cost of buying a flat beyond the sticker price.

Does the registration cap change my planning?

The cap helps at the top end but not the bottom. Because registration is capped at 30,000 rupees for property above 30 lakh, most Mumbai buyers pay the flat 30,000 rupees rather than a full 1 percent, which on a 1 crore flat would otherwise be 1 lakh. That is a small mercy in an expensive city. Stamp duty, however, is not capped, so it scales with the value of the home and remains the large number to plan for. When you budget, treat registration as a modest fixed fee and stamp duty as the percentage that grows with your purchase.

For buyers weighing locations across the region, remember that the rate and the reckoner both shift as you move out of the island city. A comparison such as our Navi Mumbai versus Thane end user guide is best read with the local duty and reckoner rates checked alongside, so the cheaper headline does not hide a heavier transaction cost.

What should a Mumbai buyer do before signing?

Settle four things before the agreement is final: the ownership structure and whether the woman sole owner rate applies, the Ready Reckoner Rate for your locality, your carpet area, and the resulting duty on the higher of reckoner value or price. Keep the IGR calculation and the GRAS challan with your file, and set the stamp duty aside as cash, since your home loan will not usually fund it. For buyers still comparing towers, a listing such as Prestige Garden Trails in Mira Road should be judged on its all in cost, price plus duty and registration, not the price alone. Get these numbers right and the registration counter holds no surprises.

Frequently asked questions

What is the stamp duty on a flat in Mumbai in 2026?

In Mumbai, stamp duty is 6 percent for a male buyer and 5 percent for a female buyer, and both figures already include the 1 percent metro cess. On top of that a 1 percent registration fee applies, capped at 30,000 rupees for property valued above 30 lakh. Confirm your figure on the official IGR Maharashtra portal.

Do women buyers pay less stamp duty in Mumbai?

Yes, a woman buying residential property in her sole name pays 5 percent instead of the 6 percent male rate, a saving of 1 percent of the value. The concession is for residential property in sole female ownership, so joint ownership with a male co-owner is charged at the male rate. Confirm current conditions on the official portal.

What value is Mumbai stamp duty calculated on?

It is calculated on the higher of your agreement value or the Ready Reckoner Rate notified for that locality. The Ready Reckoner Rate is applied to the carpet area of the flat. If the reckoner figure is higher than your negotiated price, duty is charged on the reckoner figure, so check it before you finalise the budget.

Where do I calculate and pay Mumbai stamp duty officially?

Use the official IGR Maharashtra portal at igrmaharashtra.gov.in, which provides a stamp duty calculator and Ready Reckoner Rates, with payment processed through the linked GRAS portal. Enter your locality and carpet area to read the reckoner value, then apply the rate to the higher of that value or your agreement price.
