Guidance value calculator is an online tool or formula used to estimate the minimum value of a property for stamp duty and registration purposes, based on rates fixed annually by the Karnataka government's Department of Stamps and Registration. According to the Karnataka Stamp Act, 1957 (as amended in 2025), stamp duty is levied on the higher of the guidance value or the actual sale consideration.
What is guidance value and why does it matter before you buy?
Guidance value is the floor price set by the government for a property in a specific area. It's not the market price — it's the minimum. When you register a sale deed, the sub-registrar will charge stamp duty on whichever is higher: the guidance value or the price you and the seller agreed upon. I've seen buyers get into trouble because they thought they could show a lower price on paper and pay less tax. That doesn't work. The department checks the guidance value, and if your sale price is lower, you still pay duty on the guidance value. In fact, underpaying can lead to a notice and penalty later.
How do you use the Karnataka guidance value calculator?
You can find the official calculator on the Kaveri online services portal (kaveri.karnataka.gov.in). Here's how I guide my clients to use it:
- Go to the Kaveri portal and click on 'Guidance Value' under 'Online Services'.
- Select the district, taluk, hobli, village, and the specific property type (residential, commercial, agricultural).
- Enter the exact survey number or khata details if you have them. If not, you can search by location.
- The system will show the guidance value per square foot or per acre. Multiply that by your property's area to get the total guidance value.
For example, if the guidance value for a residential flat in Whitefield is Rs 5,000 per sq ft and your flat is 1,000 sq ft, the guidance value is Rs 50 lakh. If you're buying it for Rs 45 lakh, stamp duty is still calculated on Rs 50 lakh.
What documents do you need to check the guidance value?
You don't need many documents for the calculator itself, but to verify that the guidance value applies correctly to your property, you'll need:
- Khata certificate or extract with the exact khata number.
- Survey number and sub-division details from the sale deed or mutation records.
- Encumbrance certificate (EC) to confirm there are no hidden dues that could affect value.
- Approved building plan (for constructed properties) to cross-check built-up area.
One client came to me last year, ready to register a flat in Whitefield. One EC search showed an unreleased bank mortgage the seller never mentioned — but that's a different story. The point is, you need accurate property details to get the right guidance value.
How long does a guidance value check take?
Checking the guidance value online takes about 10 minutes if you have the property details. But to get those details right — especially the khata and survey numbers — you might need a few hours or a day if you're doing it yourself. At Legal Brigade, we usually verify guidance values as part of our due diligence and return a full report in two to three days. But the online calculator itself is instant.
What happens if you skip checking the guidance value?
I've seen buyers pay a token advance without checking the guidance value, then discover at registration that the stamp duty is double what they budgeted. For example, a property with a guidance value of Rs 1 crore may attract stamp duty of 5% plus 1% registration = Rs 6 lakh. If you budgeted based on a lower sale price, you'll be short. The sub-registrar will not register until you pay the correct duty. You may have to borrow or delay the deal. Worse, if you underpay intentionally, the department can issue a penalty of up to 200% of the deficit under Section 45A of the Karnataka Stamp Act.
How much does stamp duty cost in Bangalore in 2026?
As of 2026, Karnataka charges 5% stamp duty plus 1% registration fee on properties above Rs 45 lakh (Karnataka Stamp Act schedule, 2025). For properties between Rs 20 lakh and Rs 45 lakh, it's 3% plus 1%. Below Rs 20 lakh, it's 2% plus 1%. But remember, this is calculated on the higher of guidance value or sale consideration. So if your property's guidance value is Rs 60 lakh and you're buying for Rs 50 lakh, you pay duty on Rs 60 lakh. That's Rs 3.6 lakh total (6% of 60 lakh).
Guidance value vs market value: what's the difference?
| Factor | Guidance Value | Market Value |
|---|---|---|
| Set by | Government (stamps department) | Buyers and sellers in open market |
| Purpose | Stamp duty calculation | Actual transaction price |
| Frequency of revision | Usually once a year | Changes daily |
| Can it be lower than market value? | Often yes, especially in fast-growing areas | Always the real price |
Takeaway: Always check both. You'll pay stamp duty on the higher number, so budget accordingly.
DIY guidance value check vs lawyer-led due diligence: cost, time, risk
| Method | Cost | Time | Risk |
|---|---|---|---|
| DIY (online portal) | Free | 10 minutes to 1 day (if you search for property details) | High — you may miss wrong khata or survey details, or an outdated guidance value |
| Lawyer-led due diligence (e.g., Legal Brigade) | Flat fee (typically Rs 5,000 to Rs 15,000 for apartments) | 2 to 3 days; same-day for urgent | Low — we cross-check with EC, khata, and actual sub-registrar records |
Takeaway: DIY is fine if you know the property well. But if you're relying on the seller's documents, a professional check is safer — especially for the guidance value accuracy.
How to calculate stamp duty using guidance value (step-by-step)
- Find the guidance value per unit area (sq ft or sq m) from the Kaveri portal for your property's location and type.
- Multiply by the total area of the property (built-up area for apartments, plot area for land).
- Compare with the actual sale consideration mentioned in the sale agreement.
- Pick the higher amount as the 'market value' for stamp duty.
- Apply the appropriate stamp duty percentage from the Karnataka Stamp Act based on that amount.
- Add 1% registration fee (capped at Rs 50,000 for properties above Rs 50 lakh as per 2025 rules).
Example: Apartment in Bangalore, 1,200 sq ft, guidance value Rs 6,000/sq ft = Rs 72 lakh. Sale price is Rs 65 lakh. Higher value is Rs 72 lakh. Stamp duty = 5% of 72 lakh = Rs 3.6 lakh. Registration = 1% of 72 lakh = Rs 72,000 (but capped at Rs 50,000). Total = Rs 4.1 lakh.
What if the guidance value is higher than market value?
This happens often in areas where the government hasn't updated guidance values recently or where market prices have dropped temporarily. I've had clients in Sarjapur Road who saw guidance values 20% above actual market prices. In such cases, you still pay stamp duty on the guidance value. There's no way around it — under the Karnataka Stamp Act, the sub-registrar must charge on the higher value. Some buyers try to show a higher sale price on paper to match guidance value, but that's tax evasion. Don't do it.
Frequently Asked Questions
How much does property title verification cost in Bangalore?
For a standard apartment, professional title verification including guidance value check, EC, khata, and mother deed scrutiny costs between Rs 5,000 and Rs 15,000 at most reputable firms. At Legal Brigade, we charge a flat fee — no hidden costs — and we usually return the report in two to three days. For urgent cases, same-day is possible.
How long does a property due-diligence check take?
A full due diligence including guidance value verification, EC search (30-year), khata check, and mother deed analysis takes 2 to 3 days normally. If you're in a hurry, some lawyers offer same-day service for an additional fee. In my practice, we've done same-day checks for clients who had a 24-hour token advance deadline.
Can I do property verification myself or do I need a lawyer?
You can check the guidance value online yourself for free. But a full verification — checking the EC for hidden mortgages, verifying khata authenticity, reviewing the mother deed for chain of title — requires legal expertise. I've seen DIY buyers miss a mortgage that was 15 years old and still active. A lawyer catches that before you pay your advance.
What is the difference between guidance value and circle rate?
In Karnataka, 'guidance value' and 'circle rate' mean the same thing — both refer to the minimum value set by the government for stamp duty purposes. The term 'guidance value' is officially used in Karnataka. Other states use 'circle rate' or 'ready reckoner rate'.
How often does the government update guidance values in Karnataka?
The Karnataka Stamps Department usually revises guidance values once a year, though sometimes it's every two years. The last major revision was in 2024, with an average increase of 10-15% across Bangalore. You can check the latest values on the Kaveri portal.
What if I find an error in the guidance value for my property?
If the guidance value shown on the portal is wrong (e.g., shows commercial rate for a residential property), you can file a representation with the District Registrar. You'll need to submit supporting documents like the khata, tax receipts, and an approved plan. It takes about 30 to 60 days for correction. Meanwhile, you may have to pay stamp duty at the incorrect rate and later claim a refund — a hassle I'd advise avoiding by double-checking before registration.
Is guidance value applicable for agricultural land?
Yes, agricultural land also has a guidance value per acre or per gunta, depending on the classification (dry, wet, garden). The calculation is similar — stamp duty is on the higher of guidance value or sale price. But agricultural land has different stamp duty rates (usually lower) and additional restrictions under the Karnataka Land Reforms Act.
If you've got a token advance riding on a deadline, don't gamble on it. At Legal Brigade we usually turn a full title check around in two to three days at a flat, upfront fee — send us the documents and we'll tell you exactly where you stand.
