The guideline value is the minimum value per unit of land (per square foot, per cent or per hectare) fixed by the Tamil Nadu Registration Department for each street or survey number. You can check it free on TNREGINET (tnreginet.gov.in) by choosing the Sub-Registrar office and village, then the street or survey number. It matters because stamp duty and registration fees are charged on the higher of the guideline value and the price in your deed, and because income tax rules also use this value.
Key takeaways
- Guideline value is set street-wise in towns and survey-number-wise in villages, and is revised from time to time.
- Stamp duty and registration fees are payable on the higher of the guideline value and the agreed price.
- For a sale deed in Tamil Nadu, the standard charges are 7% stamp duty plus 2% registration fee.
- If the price is well below guideline value, both buyer and seller can face income tax consequences.
- Always check the value in force on the date you plan to register, not an old printout.
What guideline value is, and what it is not
Guideline value is a government benchmark to prevent undervaluation of property for stamp duty. It is not the market price. In a sought-after pocket of R.S. Puram or Race Course, market prices can be well above the guideline value, while in some outlying villages the guideline value can sit close to, or even above, what buyers are actually paying. Banks also use their own valuers rather than the guideline value to decide how much to lend.
The value is fixed separately for land and, where applicable, for buildings (based on construction type and age). For a flat, you usually pay on the undivided share of land at guideline value plus the building value, unless the agreed price is higher.
How to check guideline value on TNREGINET
- Open tnreginet.gov.in and choose Guideline Value from the menu (listed under the search services).
- Select the zone, district (for example Coimbatore) and Sub-Registrar office.
- Select the village. For urban areas, pick the street name; for rural areas, enter the survey number and subdivision.
- Note the value, the unit (per square foot, square metre or hectare) and the land classification it applies to.
If your survey number does not appear, the value may be listed under an older survey number or the main survey number. Ask the Sub-Registrar office to confirm before you fix the deed value.
How guideline value affects your costs
| Item | How it is worked out | What to watch |
|---|---|---|
| Stamp duty (sale deed) | 7% of the higher of guideline value or agreed price | Check the current rate on TNREGINET before registration |
| Registration fee (sale deed) | 2% of the same value | A 1% concession has been announced for women buyers of property up to ₹10 lakh; confirm eligibility |
| Home loan | Based on the bank’s own valuation and your agreement value | Stamp duty is usually paid from your own funds |
| Seller’s capital gains | Stamp duty value may replace the sale price if higher | A 10% tolerance applies under the familiar Section 50C rule |
| Buyer’s income tax | Excess of stamp duty value over price may be taxed as income | Same 10% tolerance under the familiar Section 56(2)(x) rule |
Example: if you agree to buy a plot for ₹40 lakh and the guideline value works out to ₹45 lakh, stamp duty and registration fee are charged on ₹45 lakh. At 9% combined, that is ₹4.05 lakh rather than ₹3.6 lakh. Budget for this upfront; our article on the total cost of buying property covers other charges.
Income tax: why a low price can backfire
Under the Income-tax Act, 1961, Section 50C treated the stamp duty value as the sale consideration for the seller when it exceeded the actual price by more than 10%, and Section 56(2)(x) taxed the buyer on the difference in the same situation. The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026 and renumbered these provisions, while broadly carrying the policy forward. Ask your chartered accountant for the current section references on your transaction. The practical lesson is simple: a deed value far below guideline value can create a tax bill for both sides, as well as questions from the Registration Department.
Undervaluation and Section 47A
If the Sub-Registrar believes a document is undervalued, it can be referred for determination of market value under Section 47A of the Indian Stamp Act as applicable in Tamil Nadu. The buyer may then have to pay the deficit duty. Avoid deals where the seller insists on showing a much lower value in the deed and taking the rest in cash; beyond the legal risk, the unrecorded amount gives you no protection.
Revisions: keep your numbers current
Tamil Nadu revises guideline values periodically. After a court challenge to an earlier increase, the State issued revised values from 1 July 2024 for Chennai and several other cities, and further revisions have been reported in 2026. The value that applies is the one in force on the date of registration. If you signed an agreement months earlier, recheck the value before booking your registration slot.
Can I challenge a guideline value?
If the guideline value for your land is clearly out of line, for example a whole survey number valued as commercial frontage when most of it is interior agricultural land, you can take it up with the Registration Department. Guideline values are fixed through valuation committees, and representations can be made through the District Registrar. Keep evidence such as the classification in the A-Register and recent registered sale deeds in the area. Your advocate or a local document writer can advise on the practical route.
Tips for Coimbatore buyers and sellers
- Check guideline values for a shortlisted street or survey number before you negotiate; see our guide on price per cent, sq ft and acre to compare like with like.
- In fast-growing belts such as Saravanampatti, Kovilpalayam or Sulur, guideline values can differ sharply between the main road and the interior streets.
- If you are a seller, keep the stamp duty value in mind when working out capital gains.
Frequently asked questions
Is guideline value the same as market value?
No. Guideline value is the government’s minimum benchmark for stamp duty. Market value is what a willing buyer pays and can be higher or lower.
Do I pay stamp duty on guideline value or on the sale price?
On whichever is higher. If you pay more than the guideline value, duty is charged on your actual price.
Where can I check guideline value for Coimbatore?
On TNREGINET, under the guideline value search. Choose the Coimbatore district, the Sub-Registrar office, the village and the street or survey number.
What if I buy below guideline value?
You still pay stamp duty on the guideline value. If the gap exceeds the 10% tolerance, the income tax rules on stamp duty value may apply to both the buyer and the seller.
