In June 2026 a couple buying their first home in the Mumbai suburbs sat down to sign the agreement for a flat priced at one crore rupees. They had planned the down payment to the last rupee. What briefly threw them was the cost sheet line for government charges, more than six lakh rupees on top of the price, due at registration. Had the flat been registered in the wife's name alone, that line would have been a full lakh lower. The rules that produced both numbers are public, fixed, and worth understanding before you ever reach the sub registrar.

The short answer. A male buyer in Mumbai pays 6 percent stamp duty, made up of a 5 percent base rate and a 1 percent metro cess, plus a registration fee of 1 percent that is capped at 30,000 rupees. A woman buying in her own name pays 5 percent instead of 6. The duty is charged on the higher of your agreement value or the ready reckoner rate. The trade off worth knowing is that registering in a woman's name saves one percent of the price, a real and legal saving, but it must reflect genuine ownership, not a paper arrangement.

What exactly do you pay when you register a flat in Mumbai?

You pay stamp duty and a registration fee, and in Mumbai the stamp duty already includes a metro cess. For a male buyer the stamp duty is 6 percent of the value, which is a 5 percent base rate plus a 1 percent cess that funds metro rail infrastructure. On top of that sits the registration fee of 1 percent, capped so that it never exceeds 30,000 rupees. On our one crore flat, a male buyer therefore faces six lakh rupees of stamp duty and 30,000 rupees of registration, a little over six lakh in all. These are state charges and they fall due at registration, separate from the price you pay the seller and from the home loan that funds the flat itself.

Because these charges are large and arrive as cash at the counter, they belong in your plan from the first day. A buyer who has budgeted only for the flat and the down payment can be caught short, since a lender typically funds the property value rather than the government charges layered on top.

Do women buyers really pay less, and how much?

Yes, a concession lowers the stamp duty when the buyer is a woman. When the sole buyer is a woman, or when all the buyers named on the deed are women, the stamp duty in Mumbai is 5 percent rather than 6, because the base rate drops by one percentage point while the 1 percent metro cess still applies. On a one crore flat that is a saving of about one lakh rupees, and on a larger home the rupee saving grows in step with the price. The concession is a genuine policy choice meant to encourage ownership by women, and many families use it deliberately and lawfully.

Two cautions apply. The concession must reflect real ownership by the woman named, not a nominal arrangement to save duty. And the precise conditions attached to the concession are revised from time to time, so confirm the current terms on the official portal before you rely on them. Used honestly, it is one of the few large, legal savings available in the entire transaction.

How much does it add up to in rupees?

The clearest way to see the effect is to place a male buyer and a female buyer side by side on the same one crore flat. The table below assumes the agreement value is at or above the ready reckoner rate, so duty is charged on one crore.

The pattern holds at every price. Stamp duty scales with value, while the registration fee flattens out at 30,000 once the flat crosses 30 lakh. That is why on an expensive Mumbai flat the registration fee is almost a rounding item and the stamp duty is the number that really matters.

What value is the duty actually charged on?

Duty is charged on the higher of your agreement value or the ready reckoner rate for the locality, never simply on the price you would like to declare. The ready reckoner rate is a government set floor value for each area, revised by the revenue department around the first of April each year. If you negotiate a price below the ready reckoner figure, the duty is still calculated on the ready reckoner, so the floor protects the exchequer from under declaration. If your agreed price is above it, the duty follows your price. Knowing the ready reckoner for your locality before you negotiate tells you the minimum duty you will face whatever the final price. Our guide to reading the Index II document to verify a Mumbai registration shows where these registered values later appear on the record.

This rule also has a practical consequence for how you read a project's price. In a locality where the ready reckoner sits close to the market price, the two figures move together and the duty is easy to predict. In a fast rising micro market, where actual prices have run ahead of the last revision, your agreement value is likely to be the higher figure, so budget for duty on the price you pay. Either way, the safe habit is to look up the ready reckoner first, because it sets the floor and removes the guesswork from the largest single charge in your closing costs.

How do these charges sit alongside your loan and EMI?

Stamp duty and registration are cash you bring to the table, while the loan and its EMI are the long tail of the purchase. Lenders generally advance a percentage of the property value and expect you to fund the duty, the registration and the other closing costs yourself. That means the six lakh on our example flat is money you need in hand at registration, not something the bank rolls into the loan. Planning the two together, the upfront government charges and the ongoing monthly outgo, is what keeps a purchase from straining your finances in its first year. A buyer who forgets the duty can find the shortfall forces a costlier personal loan at the last minute, which quietly raises the true cost of the home. For the monthly side of that equation, our explainer on how the repo rate shapes a Mumbai home loan EMI is a useful companion.

How do you calculate and pay it, step by step?

Treat the calculation as a fixed sequence so nothing is missed. Working through the following steps gives you a firm number before you commit and a clean payment on the day.

1. Find the ready reckoner rate for the exact locality and building of the flat you intend to buy.
2. Compare that ready reckoner value with your agreement value and take the higher of the two.
3. Apply 6 percent for a male buyer, or 5 percent where the buyer is a woman, to that higher figure.
4. Add the registration fee of 1 percent, remembering it is capped at 30,000 rupees above 30 lakh.
5. Decide whose name the flat will be registered in, weighing the woman buyer concession honestly.
6. Pay the stamp duty and registration through the authorised online and bank channels before the appointment.
7. Carry the payment proof, the agreement and identity documents to the sub registrar for registration.

Run the numbers on the specific flat you are considering. A buyer weighing a launch such as Prestige Garden Trails at Mira Road should add the full 6 or 5 percent, plus registration, to the headline price so that the figure compared across projects is the true all in cost, not the marketing number.

Frequently asked questions

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

In Mumbai a male buyer pays 6 percent stamp duty on a residential sale, which is a 5 percent base rate plus a 1 percent metro cess. The duty is charged on the higher of the agreement value or the ready reckoner rate for that locality, so the figure on your cost sheet follows the larger of the two.

Do women buyers pay less stamp duty in Mumbai?

Yes. When the sole buyer is a woman, or every buyer on the deed is a woman, the stamp duty in Mumbai is 5 percent rather than 6 percent, because the base rate is lowered by one percentage point while the 1 percent metro cess still applies. On a one crore flat that concession is worth about one lakh rupees.

How much is the property registration fee in Mumbai?

The registration fee in Mumbai is 1 percent of the property value, but it is capped at a maximum of 30,000 rupees for properties valued above 30 lakh. For a home costing well above that threshold the fee stays at 30,000, which is why registration is a small line next to stamp duty on an expensive flat.

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

Stamp duty is charged on the higher of your agreement value or the ready reckoner rate notified for the locality. The ready reckoner is a government set floor value revised around the first of April each year, so even if you negotiate a lower price the duty will not fall below the figure the ready reckoner implies.

The rates in this guide reflect the stamp duty, metro cess and registration figures reported for Mumbai in 2026, as summarised in this guide to Maharashtra stamp duty and registration charges. Because ready reckoner rates and concession conditions are revised periodically, always confirm the current figures for your locality on the official Maharashtra registration portal before you commit.
