Quick Answer: A K2 challan is the payment challan you generate on Khajane 2 (k2.karnataka.gov.in), the Karnataka Government’s official treasury portal, to pay a government department online. It has two main uses: general treasury payments (department fees, fines and other government payments) and paying stamp duty and registration fees for property registration through Kaveri 2.0. There is no single published validity period — the expiry date is printed on your challan, so generate it close to the day you need it and pay before that date.
Last updated: 12 November 2026 — registration fee checked against Government of Karnataka Notification No. RD/46/MNMU/2025 dated 29 August 2025.

K2 Challan for Property Registration (Stamp Duty via Kaveri 2.0)
Most people searching for “K2 challan” are not paying a general government fee — they are buying property in Bengaluru or elsewhere in Karnataka and need to pay stamp duty and registration fees before registering the sale deed. That payment is made through Kaveri 2.0 (the Department of Stamps and Registration portal), and the actual money is paid through a K2 challan. This section explains the full process.
Stamp duty and registration fee rates (2026)
Duty and registration fee are charged on the higher of your sale price or the government guidance value for the property. If the guidance value is higher than the price you agreed with the seller, you pay on the guidance value. Check the current guidance value for your exact property on the Kaveri portal before you pay — guidance values are revised by the government from time to time.
| Charge | Rate | Charged on |
|---|---|---|
| Stamp duty — property value up to ₹20 lakh | 2% | Higher of sale price or guidance value |
| Stamp duty — property value ₹20 lakh to ₹45 lakh | 3% | Higher of sale price or guidance value |
| Stamp duty — property value above ₹45 lakh | 5% | Higher of sale price or guidance value |
| Cess on stamp duty | 10% of the duty amount | Added to the stamp duty |
| Surcharge on stamp duty (urban areas, e.g. BBMP limits) | 2% of the duty amount | Added to the stamp duty |
| Registration fee | 2% | Higher of sale price or guidance value |
Two things to know about these rates. First, the 2% and 3% stamp-duty slabs are the concessional rates for the first sale of a flat or apartment under Article 20(2A) of the Karnataka Stamp Act; a general conveyance, including most resales, is charged at 5%. Second, the registration fee was 1% until 30 August 2025 and is 2% from 31 August 2025 — the Government of Karnataka doubled it under Notification No. RD/46/MNMU/2025 dated 29 August 2025 (₹20 for every ₹1,000 of value, under Section 78 of the Registration Act, 1908). Many older guides still show 1% — they are out of date. Cess and surcharge are charged on the duty amount, not on the property value, so for a property above ₹45 lakh in an urban area they add about 0.6% of the property value. Always confirm the final figure on the Kaveri portal calculator before you pay, because rates change by government notification. For the full registration walkthrough, see our Kaveri 2.0 portal guide.
Worked example: an ₹80 lakh flat in Bengaluru
Take a flat with a sale price of ₹80 lakh, where the guidance value is not higher than the sale price:
| Item | Calculation | Amount |
|---|---|---|
| Stamp duty (5% slab, above ₹45 lakh) | 5% of ₹80,00,000 | ₹4,00,000 |
| Cess (10% of duty) | 10% of ₹4,00,000 | ₹40,000 |
| Surcharge, urban (2% of duty) | 2% of ₹4,00,000 | ₹8,000 |
| Registration fee (2%) | 2% of ₹80,00,000 | ₹1,60,000 |
| Total to pay | About 7.6% of the property value | ₹6,08,000 |
If the guidance value for the flat were ₹85 lakh instead of ₹80 lakh, every figure above would be worked out on ₹85 lakh instead. That is the single most expensive mistake buyers make — budgeting on the sale price alone and then finding the duty is higher because of the guidance value.
The Kaveri → K2 → Kaveri flow
- Calculate on Kaveri: log in to the Kaveri Online Services portal (kaveri.karnataka.gov.in), check the guidance value for your property, and use its calculator to work out the stamp duty and registration fee.
- Pay on K2: generate a challan on the Khajane 2 portal (k2.karnataka.gov.in), selecting the Stamps and Registration head of account (Head of Account 0030 — Stamps and Registration Fees), and pay online by net banking, UPI or card. Note the challan reference number and the GRN (Government Reference Number) after payment.
- Enter the GRN in Kaveri: go back to Kaveri, enter the GRN against your application so the payment is linked to your registration case.
- Book the SRO slot: once Kaveri shows the payment as verified, book your appointment at the Sub-Registrar Office (SRO) for your area and attend with the documents listed below.
K2 vs Kaveri vs BBMP — Which Portal Does What?
Three different portals are involved in a Bengaluru property registration, and mixing them up is the most common reason buyers get turned away at the SRO. Here is what each one does:
| Task | K2 (Khajane 2) | Kaveri 2.0 | BBMP |
|---|---|---|---|
| Calculates stamp duty & registration fee | No | Yes — guidance value & calculator | No |
| Takes the payment | Yes — challan payment | No — payment goes through K2 | No |
| Books the SRO appointment | No | Yes | No |
| Issues the Encumbrance Certificate (EC) | No | Yes — after registration | No |
| Handles property tax & khata | No | No | Yes |
A K2 challan is not a BBMP payment. BBMP handles property tax and khata for Bengaluru properties — it does not collect stamp duty, and there is no BBMP portal payment for a K2 challan. If someone tells you to pay a K2 challan on a BBMP or Sakala portal, that is wrong. Stamp duty is paid on the Khajane 2 portal (k2.karnataka.gov.in) after calculating it on Kaveri.
After Payment: GRN, Verification & SRO Booking
Paying is only half the job. After a successful payment, the portal gives you a GRN (Government Reference Number) — this is the proof that the government has received your money. Keep the GRN, the challan reference number and the payment receipt together; you will need all three at the SRO.
- Check the status on K2: use “Verify Payment Status” or “Search Challan” on k2.karnataka.gov.in with your challan reference number. The status should show as Paid.
- Enter the GRN in Kaveri: for property registration, enter the GRN in your Kaveri application so the payment is linked to your case.
- Wait for verification: verification is usually quick during working hours, but if Kaveri still does not show the payment, wait a few hours and check again before assuming something is wrong.
- Book the SRO slot: once the payment shows as verified in Kaveri, book your Sub-Registrar Office appointment. Book as early as you can — popular SRO slots can fill several days ahead.
If the payment fails
A failed payment is stressful, but it is usually fixable — and the worst thing you can do is pay the same challan a second time straight away.
- Do not double-pay. If the money left your account but the challan still shows as unpaid, do not pay again immediately — you may end up paying twice for the same challan.
- Wait and re-check. Bank and treasury systems can take time to reconcile. Check the status again after a few hours, and again the next day, using “Verify Payment Status” and the UTR search with your transaction reference number.
- Check with your bank. If the amount was debited, your bank can confirm whether the payment went through or failed. A failed debit is usually refunded automatically to the same account within a few working days.
- Contact the K2 helpdesk (email k2.helpdesk@karnataka.gov.in, or 080-22288801 to 080-22288805) with your challan reference number, GRN if you have one, and the bank transaction reference. They can tell you whether the payment reached the treasury.
- Refund route: if a challan was paid with wrong details or paid twice, the refund is handled through the District Registrar — ask at your Sub-Registrar Office which form and documents they need, and keep the challan, payment proof and both transaction references safe until it is resolved. Do not expect an instant refund; department refunds take time.
Errors & Fixes + SRO-Day Documents Checklist
Common errors and how to fix them
| Error | What happens | Fix |
|---|---|---|
| Wrong amount paid | The challan does not match the duty in the deed, so the SRO may refuse to register until the correct amount is paid. | Generate a fresh challan for the correct amount. If you overpaid, keep the receipt and raise it with the District Registrar — the SRO counter cannot adjust it on the spot. |
| Wrong SRO selected | The challan is linked to the wrong Sub-Registrar Office and cannot be used at the correct one. | Generate a fresh challan for the correct SRO. Check the SRO jurisdiction for your property on Kaveri before paying. |
| Wrong survey number or property details | The deed and the challan do not match, and registration can be stopped at the counter. | Generate a fresh challan with the correct details. Check the survey number and guidance value on Kaveri before paying, not after. |
| Duplicate payment | You have paid twice for the same challan. | Do not pay a third time. Keep both receipts and raise a refund claim through the District Registrar with both transaction references. |
Documents to carry on SRO day
- Original sale deed and a copy
- Aadhaar cards of the buyer, seller and both witnesses
- PAN card of buyer and seller
- Paid K2 challan, GRN and payment receipt
- Kaveri appointment slip
- e-Khata (mandatory for BBMP properties)

Khajane 2 challan is used for making online payments to Karnataka government departments (fees, taxes, fines, etc.).
Q2: Can I generate a K2 Challan (Khajane 2) without logging in?
Yes, you can use the Guest Challan Generation option on the portal.
Q3: How long is a K2 Challan (Khajane 2) valid?
There is no single published validity period for a K2 challan. Validity varies by department and challan type, and the expiry date is printed on the challan itself. Check that date before you pay: if the challan has expired, do not pay it — generate a fresh challan on the portal instead. As a rule, generate the challan close to the day you need it (for property registration, only a few days before your SRO appointment).
Q4: What if payment fails?
If money was debited but the payment failed, it is usually refunded automatically to the same account within a few working days. Check the challan status first, and if the refund has not come back, contact your bank and the K2 helpdesk with the transaction reference. Generate a new challan only after you have confirmed the first payment failed.
Q5: How to check K2 Challan (Khajane 2) status?
Go to Search Challan section on the portal → Enter reference number → Check status (Paid / Pending).
Q6: Can I cancel a K2 Challan (Khajane 2)?
No, once generated it cannot be cancelled. You must generate a fresh challan if wrong details are entered.
Q7. What is Khajane 2 DDO login?
A login for Drawing and Disbursing Officers to manage government financial transactions.
Q8. Who can use Khajane 2 DDO login?

Q10: What is UTR in Khajane 2 (K2)?
UTR stands for Unique Transaction Reference, a number that helps verify specific online transactions.
Q11: Which banks support K2 Challan (Khajane 2) payments?
State Bank of India, Canara Bank, Union Bank of India, and other treasury-approved banks.
Q12: Can NRIs use K2 Challan (Khajane 2) for payments?
Yes, NRIs can use the portal, but the payment gateway sometimes does not work from outside India. Do not use a VPN for a government payment portal — it can get the transaction blocked or flagged. Instead, ask a family member in India to generate and pay the challan using your details, or pay with an Indian bank account or card.
Q13: What is the stamp duty on a K2 challan for property registration in Karnataka?
For a sale deed, stamp duty is 2% up to ₹20 lakh, 3% from ₹20 lakh to ₹45 lakh, and 5% above ₹45 lakh, plus a 10% cess and a 2% urban surcharge on the duty amount. The registration fee is 2% (raised from 1% on 31 August 2025). All of it is charged on the higher of the sale price or the guidance value — see the rates table and worked example in the property registration section above, and confirm the final figure on the Kaveri portal calculator.
Q14: How long does a K2 payment take to reflect?
Usually the status updates within a few hours during working hours, but it can take longer if the bank and treasury systems are still reconciling. Check “Verify Payment Status” on k2.karnataka.gov.in with your challan reference number. If it still shows as pending the next day, re-check with the UTR / transaction reference, and contact the K2 helpdesk if it has not updated.
Q15: Can someone else pay a K2 challan for me?
Yes. A challan can be generated and paid by another person using the remitter’s details, because the portal offers guest challan generation without login. Make sure the name, department, purpose and amount are exactly right — a challan paid with wrong details cannot be edited afterwards.
Q16: Is there a K2 challan mobile app?
There is no official K2 mobile app promoted on the Khajane 2 portal. Use the website, k2.karnataka.gov.in, in your phone’s browser. Do not download look-alike “K2 challan” apps from app stores — they are not the government portal.
Q17: Can I pay stamp duty in cash at the SRO?
No. Stamp duty and registration fees for property registration are paid online through Kaveri and the K2 challan before your SRO appointment. Carry the paid challan, GRN and receipt to the SRO — the counter does not collect the duty in cash.
