Buying a flat or plot in Chennai in 2026 costs 9% of the property’s value in government charges: 7% stamp duty plus a 2% registration fee, worked out on the guideline value or the sale price, whichever is higher. The registration fee on sale deeds was cut from 4% to 2% from 1 April 2023 through a state gazette notification, and we found no later change to it. The 7% stamp duty component is set out in a King Stubb & Kasiva legal note on the 2023 changes.
The big exception is transfers within a family. Settlement, release and partition deeds between family members attract much lower, capped charges. The way you register has also changed this year, with more documents moving online and fewer trips to the sub-registrar’s counter.
The standard rates for common documents
The sale deed rates below come from the 2023 gazette and the legal note above. For family documents and mortgages the charges are a percentage of value subject to caps, but published summaries disagree on the cap amounts, so we have not listed figures. Always run your own document through the stamp duty check on TNREGINET before you pay.
| Document | Stamp duty | Registration fee |
|---|---|---|
| Sale deed (plot, house or flat) | 7% of value | 2% of value |
| Settlement in favour of a family member | Low rate, capped | Low rate, capped |
| Release among family members | Low rate, capped | Low rate, capped |
| Partition among family members | Low rate per share, capped | Low rate per share, capped |
| Simple mortgage | Share of loan amount, capped | Share of loan amount, capped |
For a flat, ask the builder early for the draft sale deed and check what value it states for your undivided share of land and the building together. Run that value through TNREGINET so the figure at the sub-registrar’s counter is not a surprise, and keep the 9% in your loan and down-payment plan from the start.
A worked example
Say you agree to buy a flat in Velachery for Rs 80 lakh, and the composite guideline value for that flat works out to Rs 72 lakh. Duty is charged on the higher figure, which is your price.
- Stamp duty at 7%: Rs 5.6 lakh
- Registration fee at 2%: Rs 1.6 lakh
- Total: Rs 7.2 lakh, on top of the price
Now reverse it. If the agreed price were Rs 72 lakh and the guideline value Rs 80 lakh, you would still pay Rs 7.2 lakh, because the guideline value is higher. Ask your lender early whether the loan will cover any of these charges, and plan for the rest from your own funds.
Family settlements and the 15 October change
Settlement deeds are the usual way parents pass a house to a child while alive. Because the charges are capped, a settlement in favour of a family member usually costs far less than a sale. A settlement in favour of someone outside the family is charged differently, so check the rate for your case on TNREGINET before drafting the deed.
From 15 October 2026, settlement, release, partition and revocation deeds move to paperless registration, DT Next reported. The department registers about 5.4 lakh such family documents a year. The same report said API links will check death and legal-heir certificates in real time to reduce fraud.
Other registration changes this year
- First sales from builders: From 17 August 2026, buying a new flat or plot directly from a developer must be registered through the no-visit online system. Buyers verify identity through Aadhaar with fingerprint or iris and pay online, according to DT Next.
- Home loan documents: From 15 September 2026, deposit of title deeds for bank and NBFC loans has to go through presenceless registration.
- Anywhere registration: The 2026-27 budget, presented on 5 August, announced Faceless Registration and the option to register at any designated sub-registrar office in the state, DT Next reported.
- Model hubs: 25 registration hubs are planned, with North, Central and South Chennai in the first phase.
For an inheritance, partition or settlement involving several heirs, a lawyer can check whether the family-member caps apply to each share.
