Stamp Duty & Registration Rates in Tamil Nadu 2026
Tamil Nadu has some of the highest combined stamp duty and registration charges among Indian states. Here are the current applicable rates for 2026:
| Transaction Type | Stamp Duty | Registration Charge | Total |
|---|---|---|---|
| Sale Deed (Property Purchase) | 7% of market value | 4% of market value | 11% |
| Gift Deed (Family Transfer) | 7% of market value | 4% of market value | 11% |
| Gift Deed (Blood Relatives) | 1% (capped at ₹25,000) | 1% (capped at ₹4,000) | Concessional |
| Mortgage Deed | 1% of loan amount (max ₹40,000) | 1% (max ₹10,000) | Capped |
| Lease Deed (Above 1 year) | 1% of annual rent + deposit | 1% | 2% |
| Power of Attorney | ₹100 (general) | ₹100 | Nominal |
Important note on Gift Deeds: Even when a property is gifted — meaning no payment changes hands — the donor is still required to pay stamp duty and registration. It may seem awkward that a donor is expected to pay a cost to gift property to another person, given that they are not earning anything through the change of ownership. But Tamil Nadu law requires it, and the same 7%+4% rate applies unless the transfer is between specified blood relatives, where a concessional rate applies.
Guideline Value — The Calculation Base
Stamp duty is calculated on the higher of the transaction price or the government guideline value — not just what you agree to pay the builder. Tamil Nadu guideline values are set locality-by-locality and updated periodically by the state government. On OMR, Medavakkam, and Sholinganallur, guideline values have been rising steadily in line with market prices.
If a builder agrees to show a lower price in the sale deed (an illegal practice), stamp duty is still calculated on the guideline value if it is higher. Always ensure the sale deed reflects the actual transaction price.
GST on Property Purchase in Chennai
GST is a central government levy that applies specifically to under-construction new builder properties. It does not apply to resale properties or to new builder projects that have obtained their Completion Certificate (CC).
| Property Type | GST Rate | Condition |
|---|---|---|
| Under Construction — Regular | 5% of property value | Property value above ₹45 Lakh |
| Under Construction — Affordable Housing | 1% of property value | Property value up to ₹45 Lakh AND carpet area ≤ 60 sq mt (metro) or 90 sq mt (non-metro) |
| Ready to Move (with CC/OC) | Zero | Completion Certificate obtained before sale |
| Resale Property | Zero | No GST on resale of completed property |
| Plot / Land Purchase | Zero | No GST on land purchase |
Critical for Chennai buyers: Most new builder 3 BHK projects in Chennai in 2026 — TVS Emerald Verde Vista (₹77 Lakh), TVS Emerald Aaranya (₹96.99 Lakh), Casagrand Estia (₹72 Lakh) — are under-construction and attract 5% GST. This must be included in your total cost calculation.

Home Loan Fees & GST on Processing Charges
Beyond the property purchase costs, your home loan comes with its own fee structure:
- Loan processing fee — typically 0.25%–1% of the loan amount. Major Chennai banks and HFCs (HDFC, SBI, ICICI, Federal Bank, Bajaj Housing Finance, Kotak, Tata Capital, LICHFL, IIFL, Shriram Housing Finance) all charge a processing fee.
- GST on loan processing fee — 18% — the 18% GST is widely applied to the processing fees of home loans across all major banks. On a ₹60 Lakh loan with 0.5% processing fee (₹30,000), the GST adds ₹5,400 — a small number, but it should be factored in.
- Mortgage deed stamp duty — 1% of loan amount (maximum ₹40,000) + 1% registration (maximum ₹10,000). This is registered separately from the sale deed.
- Legal verification fee — banks appoint their own lawyer to verify title. Fee varies from ₹5,000–₹15,000.
- Property valuation fee — banks appoint a registered valuer to confirm property value. Typically ₹3,000–₹8,000.
Total loan-related add-on costs for a ₹70 Lakh home loan: approximately ₹50,000–₹90,000, including processing fee + GST + mortgage deed + legal + valuation.
The Property Registration Process in Tamil Nadu
Tamil Nadu’s Sub-Registrar offices have become significantly more efficient in recent years — the state recorded over 21,300 property registrations in a single day (December 14, 2020), the highest single-day figure in three years at that time. Here is how the process works in 2026:
- Step 1 — Calculate stamp duty — determine the higher of your transaction price or the government guideline value for your locality. Use the Tamil Nadu Registration Department’s online guideline value search at tnreginet.gov.in.
- Step 2 — Pay stamp duty — stamp duty can be paid online via the SHCIL (Stock Holding Corporation of India) e-Stamping portal, or through authorised Stamp Vendors. Online payment is strongly recommended — it generates a unique e-Stamp certificate that is accepted by all Sub-Registrar offices in Tamil Nadu.
- Step 3 — Book appointment — book your Sub-Registrar office appointment online through tnreginet.gov.in. Both buyer and seller (or their POA holders) must be present with original ID proof (Aadhaar, PAN, passport).
- Step 4 — Execute Sale Deed — the Sale Deed is executed at the Sub-Registrar’s office in the presence of two witnesses. The registration officer scans and verifies documents, takes biometric data, and registers the deed.
- Step 5 — Collect registered Sale Deed — the registered Sale Deed with the Sub-Registrar’s endorsement is issued, typically on the same day or within 1–2 working days.
- Step 6 — Obtain updated Encumbrance Certificate — after registration, obtain an updated EC from tnreginet.gov.in confirming ownership transfer. This is your legal proof that the property is now in your name with no outstanding encumbrances.
Annual Property Tax in Chennai
After purchase, you will pay annual property tax to the Greater Chennai Corporation (GCC) or the relevant local body for your locality. Property taxes in Chennai are levied based on the property’s assessed annual rental value (ARV) and can range from 5% to 20% depending on various factors including property location, usage type, and floor area.
For a typical 3 BHK apartment in a gated community in Chennai, expect annual property tax in the range of ₹3,000–₹15,000 per year — a very modest cost relative to property value. Property tax can be paid online through the Greater Chennai Corporation portal or at ward offices. Chennai Corporation sends property tax bills biannually (April–September and October–March).
Money-Saving Tips for Chennai Property Buyers in 2026
- Consider CC-obtained projects to save GST — Jains Pebble Brook (Thoraipakkam, ₹88 Lakh), Jains Inseli Park (Padur, ₹79 Lakh), and Jains Alpine Meadows (Pallavaram, ₹55 Lakh) all have CC Obtained status, meaning zero GST. Compared to an equally priced under-construction flat, you save 5% of the property value — ₹3.9–₹4.4 Lakh on these projects.
- Don’t under-declare the property value — stamp duty is calculated on whichever is higher: your declared price or the guideline value. Under-declaration does not save stamp duty (the guideline value kicks in) but does expose you to IT scrutiny and penalty. Declare the actual transaction price.
- Claim Section 80C deduction on stamp duty — stamp duty and registration charges paid for a residential property are eligible for deduction under Section 80C of the Income Tax Act, up to the overall ₹1.5 Lakh Section 80C limit. This partially offsets your stamp duty outflow through tax savings.
- Claim home loan interest deduction under Section 24(b) — deduct up to ₹2 Lakh per year on home loan interest for a self-occupied property. For a ₹70 Lakh home loan at 8.75% interest, you are paying approximately ₹6 Lakh in interest in Year 1 — the ₹2 Lakh deduction at the 30% tax bracket saves ₹60,000 annually.
- First-time buyers — claim Section 80EEA — first-time homebuyers whose loan was sanctioned in the eligible window can claim an additional ₹1.5 Lakh deduction on home loan interest under Section 80EEA, over and above the Section 24(b) limit. Consult a tax advisor for current eligibility.
- Use the online stamp duty calculator — Tamil Nadu’s tnreginet.gov.in has a built-in stamp duty calculator. Use it before finalising your budget to get an exact figure based on your locality’s guideline value.
