Tamil Nadu charges 7% stamp duty plus 4% registration fee on a sale deed for male buyers, calculated on whichever is higher — guideline value or sale price. Women buyers get a 2% rebate, paying 5% stamp duty instead of 7%. On an ₹80 lakh flat, a male buyer pays ₹5.6 lakh stamp duty plus ₹3.2 lakh registration, totaling ₹8.8 lakh.
Quick answer: Calculating Tamil Nadu stamp duty comes down to one formula — guideline value or sale price, whichever is higher, multiplied by the applicable rate — and the rate itself depends on the transaction type and buyer. Standard sale deeds cost 7% stamp duty + 4% registration for male buyers, dropping to 5% stamp duty for women buyers registering solely in their name. Gift deeds to blood relatives are far cheaper at 1% + 1%, while gift deeds to others and residential lease agreements follow different rates again. On an ₹80 lakh flat, a male buyer's total works out to ₹8.8 lakh in stamp duty and registration combined. Always verify the guideline value on TNREGINET before finalising a sale price — paying below guideline value doesn't reduce your stamp duty, since duty is calculated on the higher of the two figures regardless.
What is Stamp Duty?
Stamp duty is a state-levied tax paid when registering a property. In Tamil Nadu, it is charged on the guideline value or the actual sale price, whichever is higher.
