Stamp Duty, GST & Registration Fees: Agent's Cost-of-Acquisition Guide

Why the Full Cost Number Is Your Responsibility

A buyer asks you what a flat will actually cost. If you quote the agreement value and stop there, you have given an incomplete answer, and the gap shows up later as stamp duty, GST, registration, and incidental charges that can add 8 to 12 percent on top of the headline price. The client who budgeted for the wrong figure remembers who gave them that figure.

Section 10(c) of the RERA Act bars agents from unfair practices, including false statements about services. Apart from the law, an understated figure costs you the client's trust.

Know the full breakdown, and recheck each rate before you give a client a final number.

Maharashtra Stamp Duty Rates in 2026 by Zone

Stamp duty on a conveyance in Maharashtra starts from Article 25(b) of the Stamp Act schedule: 5 percent of market value in municipal corporation, municipal council, nagar panchayat, MMRDA-rural and other urban areas, and 4 percent in gram panchayat areas. Many areas add 1 percent more as metro cess or a local-body surcharge. Which one applies depends on the location, so check the IGR Maharashtra calculator for the exact property instead of assuming a city rate.

Since 1 April 2021, a woman buying a residential unit pays 1 percent less. Ask the sub-registrar how this applies to a joint purchase before you quote a figure.

Run the exact figure through a stamp duty calculator before advising any client.

The Ready Reckoner Rate Trap

The Ready Reckoner Rate, also called the Annual Statement of Rates, is the government's notified minimum value for property in a given area. The state revises it annually. Every locality has a per-square-metre value the registration department treats as the floor.

Stamp duty is calculated on the higher of the agreement value or the Ready Reckoner value. This is where buyers and their advisors get caught. If a client negotiates a flat at ₹80 lakh in an area where the Ready Reckoner value works out to ₹92 lakh, stamp duty is charged on ₹92 lakh, not on what was actually paid.

Under-declared transactions, where the agreement value is artificially lowered to save duty, do not escape this. The Sub-Registrar applies the Reckoner floor regardless. Always check the current Reckoner rate for the exact survey number and building before you commit to a cost figure. A property advisor who skips this step will quote a number that the registration office overrides on the spot.

GST: Under-Construction Versus Ready Possession

GST applies only to under-construction property. Once a project has received its Occupancy Certificate, the sale is treated as a completed property and attracts zero GST. This single distinction changes the total cost materially.

Under-construction residential property is taxed at 5 percent without Input Tax Credit. Affordable housing, defined as units priced under ₹45 lakh with carpet area up to 60 square metres in metro areas, is taxed at 1 percent. Ready-possession or OC-received flats carry no GST at all.

Take two flats at the same ₹70 lakh agreement value in Pune. The under-construction flat adds 5 percent GST, which is ₹3.5 lakh, on top of stamp duty and registration. The ready flat with OC adds zero GST. That is a ₹3.5 lakh swing on identical headline prices. Work this out for clients using a GST on property calculator so they compare like with like before deciding.

Registration Charges and the Four-Month Window

Registration is charged at 1 percent of the property value, capped at ₹30,000. For any property valued above ₹30 lakh, the registration fee is effectively flat at ₹30,000. For lower-value properties it works out as 1 percent of value.

At the Sub-Registrar office, the parties must produce the executed sale agreement, proof of stamp duty payment, PAN cards of buyer and seller, Aadhaar, passport-size photographs, and the property documents including the index and prior chain where applicable. Both parties or their constituted attorneys must be present for biometric capture.

There is a deadline. Under the Registration Act, a document generally has to be presented for registration within four months of execution. If you are near that date, ask the sub-registrar what applies. Build the full outgoing into a total cost of purchase calculator so the buyer sees stamp duty, GST, and registration in one figure rather than discovering them one at a time.

The Income Tax Angle on Stamp Duty

Stamp duty and registration charges paid on a residential property are deductible under Section 80C of the Income Tax Act, up to a combined limit of ₹1.5 lakh, for payments made up to 31 March 2026. The deduction is available in the financial year the payment is actually made, and only under the old tax regime.

From FY 2026-27, this benefit moves to Section 123 of the new Income Tax Act 2025. The limit stays at ₹1.5 lakh and remains tied to the old regime. The section number changes, the substance does not.

Flag this to buyers who are close to a financial year boundary. A client completing registration in March 2026 claims under Section 80C for AY 2026-27. One completing in April 2026 claims under Section 123. Ask the client to confirm the tax treatment with their tax adviser.

Agent Checklist and Exam Connection

Before you quote any client a total purchase cost, run these five questions. One, what zone is the property in, and does the female-buyer concession apply to the actual ownership structure? Two, is the agreement value or the Ready Reckoner value higher, and which one will duty be charged on? Three, is the property under-construction or OC-received, and what GST rate follows from that? Four, what is the registration fee after the ₹30,000 cap, and is the four-month window being tracked? Five, which financial year is registration falling in for the Section 80C or Section 123 deduction?
