After the down payment, stamp duty and registration charges are usually the biggest one-time cost of buying a home. In Tamil Nadu they add roughly 11% to the value of a sale deed, so it pays to understand exactly how they’re calculated before you book.
This guide explains the current rates, how guideline value affects what you pay, worked examples, and the step-by-step registration process in Chennai.
What are stamp duty and registration charges?
- Stamp duty is a tax the state government charges on property documents such as a sale deed. Paying it makes the document legally valid.
- Registration fee is the fee for recording the document with the Registration Department at the Sub-Registrar office, so the transfer of ownership becomes part of the public record.
Both are paid by the buyer, usually on the day of registration, unless the sale agreement says otherwise.
Current stamp duty and registration charges in Tamil Nadu (2026)
| Document | Stamp duty | Registration fee | Total |
|---|---|---|---|
| Sale deed (conveyance) | 7% | 4% | 11% |
| Gift deed to family members | Lower, fixed rates apply | Lower, fixed rates apply | Varies |
| Settlement / partition among family | Lower rates apply | Lower rates apply | Varies |
| Lease / rental agreement | Depends on rent and term | Depends on rent and term | Varies |
Women buyers: A small concession on the registration fee (about one percentage point) applies to properties valued up to ₹10 lakh purchased only by women, from April 2025. Stamp duty itself is the same for men and women.
Rates can change through government orders. Always confirm the current stamp duty rates for your document type on TNREGINET or with the Sub-Registrar before registration.
How is stamp duty calculated? Guideline value vs market value
In Tamil Nadu, stamp duty and the registration fee are charged on the guideline value or the sale value, whichever is higher.
- Guideline value is the minimum value fixed by the government for each street or survey number. You can check it on TNREGINET.
- Market value / sale value is the price you actually pay as recorded in the sale deed.
So if you buy below the guideline value, you still pay duty on the guideline value. If you pay more than the guideline value, you pay duty on your actual price.
Example 1: Sale value higher than guideline value
| Amount | |
|---|---|
| Sale value | ₹60,00,000 |
| Guideline value | ₹48,00,000 |
| Value used | ₹60,00,000 |
| Stamp duty (7%) | ₹4,20,000 |
| Registration fee (4%) | ₹2,40,000 |
| Total | ₹6,60,000 |
Example 2: Guideline value higher than sale value
| Amount | |
|---|---|
| Sale value | ₹40,00,000 |
| Guideline value | ₹45,00,000 |
| Value used | ₹45,00,000 |
| Stamp duty (7%) | ₹3,15,000 |
| Registration fee (4%) | ₹1,80,000 |
| Total | ₹4,95,000 |
You can use the stamp duty calculator on TNREGINET to estimate your charges for a specific property.
Apartments: UDS and the construction agreement
When you buy a flat in Chennai, especially an under-construction one, the transaction is usually split into two documents:
- Sale deed for the undivided share of land (UDS) — your proportionate share of the land the building stands on.
- Construction agreement with the builder for the flat itself.
The charges on each can differ from a single completed-flat sale deed. Ask your builder for a written breakdown of the UDS value, construction cost, stamp duty and registration fees before you book, so there are no surprises.
