Stamp duty in Tamil Nadu is the state tax payable on property transfer documents (Sale Deed, Gift, Mortgage, etc.) to make them legally enforceable. Per the official TNREGINET Duty and Fees schedule, Conveyance (Sale) attracts 7% stamp duty on the market value or guideline value (whichever is higher), plus a 2% registration fee — total 9% of the property value. Stamp duty is calculated and paid via the TNREGINET portal before registration at the Sub-Registrar Office.

Procedure to estimate, pay, and file stamp duty for a Tamil Nadu property registration via TNREGINET.
Stamp duty is calculated on whichever is higher: the agreed sale value or the government-fixed guideline value for the SRO/village. Look up the guideline value via TNREGINET before agreeing on price.
Visit https://tnreginet.gov.in/portal/ and use the stamp-duty calculator: 7% stamp duty + 2% registration = 9% of the qualifying value (per the TNREGINET Duty and Fees schedule).
Open portalTamil Nadu has announced concessional registration rates for women buyers under specific value thresholds. Confirm current applicability and exact percentages on the TNREGINET portal before relying on a discounted rate.
Stamp duty can be paid via e-Stamping (online) or Demand Draft. Generate the e-Stamp certificate from the TNREGINET portal.
Schedule registration at the relevant SRO with the Sale Deed, e-Stamp certificate, identity proofs, photographs, and witnesses. Registration is mandatory within 4 months of execution.
These are the patterns that break deals if missed.
A single stamp-duty calculation is one form-fill. Acquisition teams modeling deal economics across 20+ active leads — comparing guideline vs market, factoring women-buyer concessions, modelling impact of guideline-rate hikes — repeat the calculation manually for every revised offer. Proquiro models stamp-duty cost in deal-feasibility calculations automatically and refreshes when guideline values change.

A 2% registration fee is payable separately, bringing the total transaction cost to 9% of the property value.
Tamil Nadu has announced concessional registration rates for women buyers under specific value thresholds. Stamp duty (7%) itself does not have a gender-based concession.
Because rate schedules change with state budgets, confirm current concession percentages and value caps directly on the TNREGINET portal before relying on a discounted figure.
Whichever is higher. If the agreed sale price exceeds the guideline value for the SRO/village, stamp duty is on the sale price. If the guideline value is higher, stamp duty is on the guideline value.
This prevents under-valuation but means buyers in fast-rising micro-markets may pay duty on the inflated guideline value even when their negotiated price is lower.
Use the TNREGINET portal's e-Stamping flow. Calculate the duty using the built-in stamp-duty calculator, generate an e-Stamp certificate, and pay via net banking, UPI, or DD.
The e-Stamp certificate must be presented at the Sub-Registrar Office during registration.
