Ready Reckoner Rates 2026-27 Mumbai: Stamp Duty and Total Cost of Buying

When the Maharashtra government announced that ready reckoner rates 2026-27 would stay frozen at 2025-26 levels from 1 April 2026, most buyers read it as good news and moved on. It is good news. The industry had expected a 4-5% increase after a 3.39% rise in Mumbai and a 7.7% rise in Thane the year before. But the freeze is only one line in a much longer bill. Stamp duty, registration, GST and a handful of smaller charges can add 7% to 13% to the price you agree with the seller.

That gap catches buyers out every season. A family that has budgeted Rs 1 crore for a flat in Thane may need closer to Rs 1.12 crore on the day of registration, and banks do not finance most of these charges. With the RBI raising the repo rate to 5.50% on 7 October 2026, every lakh of cash you need upfront now matters more.

We at Godrej Properties MMR have put together the full cost picture for Mumbai, Thane and Navi Mumbai, with worked examples for ready and under-construction homes, so you can see your real number before you book.

The ready reckoner rate (RR rate) is the government’s minimum value for property in each zone and sub-zone of Maharashtra. It is published by the Inspector General of Registration and Controller of Stamps. Stamp duty is charged on the agreement value or the RR value, whichever is higher. So the RR rate acts as a floor under your stamp duty bill.

For 2026-27, Revenue Minister Chandrashekhar Bawankule confirmed the rates would stay at status quo to avoid adding a financial burden on buyers. CREDAI and other industry bodies had lobbied against a hike. The rates in force today are therefore the April 2025 revision:

Mumbai’s 6% is a 5% base rate plus 1% metro cess. Thane and Pune add a further 1% local body tax, which takes them to 7%. Sources disagree on whether Navi Mumbai is charged at 6% or 7%, so check the exact rate for your property on the IGR Maharashtra portal before you budget.

A frozen ready reckoner rate does not mean frozen prices. Knight Frank put Mumbai’s weighted average price at Rs 37,064 per sq ft in Q3 2026, up 5% year on year. Market prices now sit well above RR values in most of MMR, so stamp duty is usually charged on your agreement value.

Here is what goes into the all-in cost of a home in MMR, beyond the agreement value:

• Stamp duty: 6% in Mumbai, 7% in Thane, on the higher of agreement value or RR value. Women buying in their sole name pay 1% less.
• Registration fee: 1% of the property value, capped at Rs 30,000. On most MMR homes, you pay the full Rs 30,000.
• GST: 5% on under-construction homes without input tax credit, or 1% on affordable homes (up to 60 sq m carpet and Rs 45 lakh in metro areas, which include all of MMR). No GST on ready homes with an occupation certificate, or on resale flats.
• TDS: 1% deducted by the buyer and paid to the government when the price is Rs 50 lakh or more. It is not an extra cost, but it must be paid on time.
• Developer charges: society formation, legal fees, infrastructure charges and advance maintenance for 12-24 months. These vary widely by project, so ask for a written cost sheet that lists each one before you pay the booking amount.
• Loan costs: processing fees, typically up to 0.5% of the loan, plus documentation charges.

Note the Rs 45 lakh limit for affordable GST covers the total consideration, including parking and club charges. A Rs 44 lakh flat with a Rs 2 lakh parking slot is no longer “affordable” for GST purposes.

We worked through three common buyer profiles. The figures cover government charges only. Add developer charges and loan fees on top.

Outside BMC limits, municipal corporation areas such as Thane, Navi Mumbai and Panvel typically charge 7% for men and 6% for women: 5% base duty plus 1% local body tax and 1% metro cess. A joint purchase by a man and a woman pays the full 7%. Confirm the rate for your exact node or village on the IGR Maharashtra portal before you register.

Two things stand out. First, a ready home with an occupation certificate saves the 5% GST entirely, which on a Rs 1 crore flat is Rs 5 lakh. That partly explains why ready homes command a premium. Second, the women’s concession saves 1% of value, Rs 1 lakh on a Rs 1 crore flat, but only when a woman is the sole buyer. Most sources say a joint purchase with a male co-owner is charged at the full rate.

In older buildings, distressed sales and some outer-MMR pockets, the agreed price can fall below the RR value. In that case, stamp duty is charged on the RR value. If your agreement is Rs 90 lakh but the RR value is Rs 1 crore, you pay 6% of Rs 1 crore in Mumbai, which is Rs 6 lakh, not Rs 5.4 lakh.

There is an income tax angle too. Under Section 56(2)(x) of the Income Tax Act, if the stamp duty value exceeds the price you pay by more than 10%, the difference can be taxed as income in your hands. The seller faces a matching rule under Section 50C. A deal that looks cheap on paper can carry a tax bill later.

Maharashtra has also introduced a penalty of up to Rs 1 lakh for insufficient stamp duty, on top of recovering the shortfall. Undervaluing to save duty is not worth the risk.

For a sense of where market prices sit against RR values today, see our analysis of which Mumbai areas are rising fastest in 2026.

1. Look up the RR value for your survey or CTS number on the IGR Maharashtra portal and compare it with the agreement value.
2. Confirm the stamp duty rate for the municipal area: 6% in Mumbai, 7% in Thane and Pune, and verify Navi Mumbai or Panvel for your exact location.
3. Decide ownership early. If a woman will be the sole owner, the 1% concession applies. Changing names later costs fresh stamp duty.
4. Ask the developer for a full cost sheet showing GST, parking, club, legal and maintenance charges as separate lines.
5. Keep cash ready. Banks typically lend 75-90% of the property value and do not fund stamp duty or registration in most cases.
6. Check the RERA registration and carpet area before paying anything. Our MahaRERA 2026 checklist for homebuyers covers what to verify.

Godrej Properties Limited, the third-party developer behind several projects across the region, has homes at both ends of the cost table above. Under-construction launches attract GST but offer construction-linked payment plans, which spread the cash outflow over several years. Ready homes avoid GST but need the full amount upfront.

At Godrej City Panvel, where 1 BHK homes start around Rs 79 lakh, the all-in government charges on an under-construction unit come to roughly 12% of the price. At the Godrej Thane 18-acre project in Thane West, priced from about Rs 1.05 crore, a woman buyer would pay 6% stamp duty instead of 7%, saving over Rs 1 lakh. You can read more about the developer on the Godrej Properties website.

We help buyers compare cost sheets line by line, so the number you budget is the number you pay.

Q: Have ready reckoner rates 2026-27 increased in Maharashtra?

No. The IGR Maharashtra kept rates at 2025-26 levels from 1 April 2026. The last revision, in April 2025, raised Mumbai’s rates by 3.39% and Thane’s by about 7.72%. Industry had expected a 4-5% hike this year, but the government chose a freeze to ease costs for buyers.

Q: What is the stamp duty in Mumbai in 2026?

Stamp duty in Mumbai is 6% for men, made up of a 5% base rate and 1% metro cess. Women buying as sole owners pay 5%. Registration is 1% of the value, capped at Rs 30,000. Duty is charged on the agreement value or the ready reckoner value, whichever is higher.

Q: Is GST charged on ready-to-move flats?

No. GST applies only to under-construction homes, at 5% for standard homes and 1% for affordable homes. Ready homes with an occupation certificate and resale flats carry no GST. On a Rs 1 crore home, buying ready saves about Rs 5 lakh in GST.

Q: Can I include stamp duty in my home loan?

In most cases, no. Banks lend against the property value and generally exclude stamp duty and registration. Some lenders include these in the overall cost for loan-to-value calculations, but you should plan to pay them from your own funds.

Q: Do joint buyers get the women’s stamp duty concession?

Most sources say the 1% concession applies only when a woman buys alone. Where a man is a co-owner, the full rate usually applies. Confirm the treatment with your sub-registrar or lawyer before deciding on ownership.

Q: What happens if my agreement value is below the ready reckoner rate?

Stamp duty is charged on the higher RR value. If the gap exceeds 10%, the difference may also be taxed as income for the buyer under Section 56(2)(x). Short-paying stamp duty can attract a penalty of up to Rs 1 lakh.

The freeze on ready reckoner rates 2026-27 is a small saving, but the real budget lies in stamp duty, GST and registration, which together add 6% to 13% to your price.
