Stamp duty is the largest single cheque most Maharashtra buyers write after the flat itself, and the most misunderstood. It arrives earlier than expected, it differs by city in ways brochures never mention, and a one-word choice on the document, whose name goes first, can move it by a lakh. Here is the whole bill, computed honestly.
Key takeaways
- Mumbai charges 6 percent stamp duty for men, 5 for women, including the 1 percent metro cess; Pune, Thane and Nagpur charge 7 and 6 percent because a local body tax stacks on top (2026 rates).
- Registration is 1 percent capped at Rs 30,000 above Rs 30 lakh, so it is effectively flat on urban purchases.
- The women's 1 percent concession requires every buyer on the document to be female; the 15-year resale lock-in on it has been removed as of 2026.
- Duty is charged on the agreement value or the government's ready reckoner value, whichever is higher, and it is due at agreement registration, years before possession on under-construction purchases.
Neha's first surprise
Neha, buying her 2BHK in a Mulund redevelopment project (illustrative, as always), had budgeted Rs 1.05 crore for a Rs 1 crore flat, assuming "closing costs" behaved like a broker's fee. Her CA corrected the math in one line: on Rs 1 crore in Mumbai, stamp duty alone is Rs 6 lakh, registration Rs 30,000, and both are due the month she signs the agreement for sale, not at possession two years later. Registering the flat jointly with her mother, with both women as the only buyers, would have cut the duty to Rs 5 lakh. The cheque she almost mis-timed was the size of a car.
What stamp duty actually is
Stamp duty is a state tax on the transaction document itself. Unstamped or understamped documents are not admissible as evidence, which means an unstamped agreement protects nobody. Think of it as the toll for entering the legal system: pay it and the state's courts, registries and records stand behind your ownership; skip it and your Rs 1 crore purchase rests on paper with no legal weight. That is also why it cannot be deferred: the protection starts when the agreement does.
The rates, city by city
Maharashtra's headline duty is 5 percent, but nobody pays the headline. Urban transactions carry a 1 percent metro cess (funding transport infrastructure), and municipal corporations outside Mumbai add a 1 percent local body tax. As reported for 2026:

Three fine-print rules do most of the damage when missed:
- Higher-of-two valuation. Duty is computed on your agreement value or the government's ready reckoner valuation for that building, whichever is higher. A genuine bargain below the reckoner rate still pays duty at the reckoner value.
- The women's concession is all-or-nothing. The 1 percent reduction applies only when every buyer on the document is a woman. Add a husband as co-owner and the concession vanishes. The 15-year resale lock-in that made buyers wary of this concession has been removed as of 2026, so an all-women registration is now a clean Rs 1 lakh saving per crore with no strings on exit.
- Registration is capped, not proportional. 1 percent, but never more than Rs 30,000 (for properties above Rs 30 lakh). On any urban flat, treat it as a flat fee.
When the money leaves: earlier than you think
On an under-construction purchase, the agreement for sale is executed and registered near the start, when you have paid perhaps 10 to 20 percent of the price. Stamp duty and registration are due in full on that day. On our Rs 1 crore Pune example, that is Rs 7.3 lakh leaving your account in the same season as the booking amount and the down payment, the exact pile-up month we mapped in the money timeline of buying a flat. Budget it there, not at possession.
Two smaller notes for completeness: you also pay a nominal Rs 100 to Rs 200 per document as handling and filing fees, and GST on under-construction purchases (5 percent, or 1 percent affordable) is a separate central levy on top, compared properly in under-construction vs ready-to-move.
Never route stamp duty through the builder as a lump "government charges" line. Pay it yourself through the official GRAS portal or bank franking, in your name, and keep the challan. The challan is your proof; a builder's consolidated receipt is not. Buyers who paid "government charges" to promoters who never registered the agreement fill a sad shelf of MahaRERA orders.
What the duty buys you: the registered record
The registered agreement is the anchor document of every protection covered on this blog: the carpet area you can measure against, the possession date your delay interest runs from, the payment schedule the 10 percent cap polices. It is also what makes your flat visible in the state's records, searchable in an encumbrance certificate for the next buyer. In a registered MahaRERA project, the agreement should follow the model agreement's mandatory clauses, and the 12-document checklist shows where it sits in the full file. New to the regulator itself? Start with what MahaRERA is.
The planning moves that legitimately save money
- All-women registration where the family's finances genuinely support it: 1 percent saved, lock-in free as of 2026.
- Time the agreement, not the duty. Rates change in state budgets, and reckoner valuations revise; a purchase straddling a revision date should check both sides of it.
- Never understate the agreement value. The classic "save stamp duty in cash" proposal transfers all its risk to you: your refund rights, delay interest and resale basis all shrink to the understated number, while the duty saving mostly accrues to the seller's tax position.
Before any of this arithmetic matters, the project itself has to deserve the cheque. The Rs 499 ReraGenie buyer report reads a Maharashtra project's complete MahaRERA record, its progress, promoter history and complaint file, so the largest tax payment of your life lands on a project whose filings have earned it. Run it before the agreement date is fixed: sign up on ReraGenie.
The one-line summary
Six percent in Mumbai, seven in Pune, one back for all-women documents, Rs 30,000 to register, computed on the higher of your price and the government's valuation, due the day the agreement is signed. Put those numbers in the budget on day one and the biggest cheque after the flat stops being a surprise.
