- Guideline value = minimum registrable value set by the government for an area.
- Check free on tnreginet.gov.in → Guideline Value.
- Duty is on the higher of sale value or guideline value.
- Normal sale: 7% stamp duty + 4% registration.
- Family transfers: 1% + 1% (subject to caps).
- Women buyers: a 1% registration concession on properties up to ₹10 lakh (from April 2025).
What guideline value means
The guideline value (also called the government value or ready-reckoner rate) is the minimum price the government recognises for a property in a specific location. It exists to stop under-valuation of property in sale deeds, which people used to do to dodge stamp duty. You cannot register a property below its guideline value — so it acts as the floor for your registration and the base for calculating your duty.
How to check guideline value on TNREGINET
- Go to tnreginet.gov.in and click Guideline Value.
- Choose the zone → sub-registrar office → village → street, or switch to survey-number search for a specific plot.
- Enter the land classification (residential, commercial, agricultural) if asked.
- The portal displays the guideline value per unit (per sq ft for buildings, or per acre/cent for land) for that location.
It's free and doesn't need a login for a basic value check — useful before you even start negotiating a purchase.
How guideline value decides your stamp duty
This is the part that costs (or saves) you money. Stamp duty and registration are always charged on the higher of two figures:
Duty base = higher of (sale value in the deed) or (government guideline value)
So if a flat's guideline value is ₹50 lakh but you agree a price of ₹45 lakh, duty is still charged on ₹50 lakh. If you agree ₹55 lakh, duty is on ₹55 lakh. You never pay duty on less than the guideline value.
Tamil Nadu stamp duty & registration rates
| Deed type | Stamp duty | Registration |
|---|---|---|
| Sale / conveyance | 7% | 4% |
| Gift / settlement / release / partition (within family) | 1% | 1% (subject to caps) |
For a normal purchase, the combined statutory cost is roughly 11% of the duty base — a big number, so knowing the guideline value in advance lets you budget accurately. From April 2025, women buyers get a 1% cut in registration (from 4% to 3%) on properties valued up to ₹10 lakh.
A worked example
Guideline value ₹60 lakh, sale value ₹58 lakh. Duty base = ₹60 lakh (the higher). Stamp duty 7% = ₹4,20,000; registration 4% = ₹2,40,000; total ≈ ₹6,60,000 on top of the price. Our stamp duty calculator does this instantly.
Why buyers should always check it first
- It sets your real registration cost — budget for it before you commit.
- A big gap between sale price and guideline value can be a red flag to investigate.
- It helps you judge whether an asking price is reasonable for the area.
- Guideline values are revised periodically, so always check the current figure.
Guideline value vs market value — they're not the same
People often confuse the two. The guideline value is a government figure for calculating duty; the market value is what the property actually sells for. In fast-growing areas the market value is usually higher than the guideline value, and you'll register (and pay duty) on your actual, higher sale price. But in some older or over-assessed pockets, the guideline value can be higher than the real market price — and that's where buyers get an unpleasant surprise, because duty is still charged on the higher guideline figure. Checking the guideline value early tells you which situation you're in before you sign anything.
When the guideline value is higher than your price
If a property's guideline value is genuinely higher than the fair market price (it happens after slowdowns or in wrongly-assessed streets), you have a few options: proceed and pay duty on the guideline value; negotiate the deal knowing your true statutory cost; or, in appropriate cases, apply to the authorities for a revision of the guideline value with supporting evidence. Because guideline values are revised only periodically, a temporary mismatch can persist — so always factor the current guideline figure into your total budget, not just the asking price.
Buyer checklist before you register
- Check the current guideline value on TNREGINET for the exact survey number/street.
- Compare it with the agreed sale price — note which is higher.
- Compute duty on the higher figure and add it to your budget.
- Verify the property's patta and encumbrance status separately.
- Confirm any concessions (women buyers, family transfers) you may qualify for.
