A buyer in HSR Layout closed a resale flat, moved in, and six months later applied to transfer the khata into his name. The application bounced. The reason was four years of unpaid property tax the previous owner had quietly let pile up, arrears that were now legally his to clear before anything could move. He had checked the sale deed, the encumbrance certificate and the loan papers. The one public record he had not opened was the property tax account, and it was the one that stopped him cold.

The short answer. In Bengaluru, unpaid BBMP property tax stays attached to the property and passes to the new owner, and outstanding dues can stall both the khata transfer and the sale registration. You can check the tax status yourself for free at bbmptax.karnataka.gov.in using the property identification number or the application number. The trade off is stark. Two minutes on the tax portal and a demand for three years of paid receipts costs you nothing, while skipping it can leave you paying someone else's tax bill and unable to complete your own khata transfer.

Why does a seller's unpaid tax become the buyer's burden?

Because property tax is a charge on the property, not merely a debt of the person who owned it. When you buy a flat with tax arrears, those arrears do not stay behind with the seller. They travel with the property, so the municipal body looks to the current owner to clear them regardless of who ran them up. This is why a clean sale deed does not protect you here. The deed transfers ownership, and it transfers the tax liability along with it.

For a buyer the lesson is that price negotiation and paperwork are not the whole picture. A flat that looks like a bargain can carry a hidden liability equal to years of unpaid tax plus penalties, and you inherit that the moment the property becomes yours. The only defence is to check before you pay, not after.

How exactly do arrears block a khata transfer and registration?

Arrears block you at two separate government counters, and both matter. At the khata transfer stage, BBMP checks the property tax status when a transfer application is made, and outstanding arrears stop the transfer from going through until they are cleared. Since the khata is essential to hold the property cleanly in your name, a blocked transfer is not a minor inconvenience.

At the registration stage, the sub registrar's office requires the seller to produce the latest property tax paid receipt, and unpaid property tax can delay or prevent registration of the sale deed itself. So the tax account sits directly in the path of the two steps that actually make you the owner. If it is not clean, the machinery simply does not turn, and you can find yourself having paid for a flat you cannot fully transfer. For how the khata itself now works, our guide to the mandatory BBMP e-Khata explains the record this tax status feeds into.

How do you check the tax status yourself?

You check it on the official BBMP tax portal in a couple of minutes. Go to bbmptax.karnataka.gov.in and search using the property identification number, known as the PID, or the SAS base application number. If you do not have those, you can often search by the previous application number or owner name in the property details section. The portal pulls up the property's details, including the tax paid last year and the amount due for the current year.

Read two things carefully. First, whether the current year is paid, and second, whether there is any accumulated backlog from earlier years. A property that is current for this year can still carry old arrears, so do not stop at the latest receipt. The whole point is to see the full history, because it is the buried old dues that ambush buyers at the transfer counter later.

It also helps to understand how the tax is assessed, because that tells you whether the amount shown is even correct. Bengaluru property tax runs on a self assessment system, where the owner declares the property's built up area, usage and zone, and the tax follows from that declaration. An owner who under declared the area to lower the tax has created a discrepancy that can surface later as a demand for the shortfall. So when the portal figure looks suspiciously low for the size of the flat you are standing in, that gap is worth questioning, since a future correction of the assessment can land on you as the new owner.

What should you demand from the seller before paying?

Ask for the last three years of property tax paid receipts before you part with any advance. Three years is a sensible window because it surfaces a pattern of payment rather than a single convenient receipt, and it lines up with what registration and transfer offices expect to see. Match the details on those receipts, the PID and the owner name, against the portal and against the sale deed, so you know the receipts belong to the exact property you are buying.

If the seller cannot produce the receipts or the portal shows a backlog, treat that as a price and timeline issue to settle in writing before the deal proceeds, not a surprise to absorb afterwards. Our resale flat NOC and dues checklist sets this into the wider list of dues a resale buyer should clear.

What if the property already has arrears?

If arrears exist, the cleanest path is to make the seller clear them before registration, in writing. Because the liability follows the property, you do not want to close the deal and then chase a former owner for money the municipality is now demanding from you. Build a condition into the agreement that all property tax dues up to the date of sale are cleared by the seller, supported by an updated paid receipt from the portal, and hold back a portion of the payment until that receipt exists.

Where a seller insists the buyer absorb old dues, that is a real cost that belongs in the price negotiation, not a favour to grant. The rupee value of clearing years of arrears and penalties can be significant, and it is entirely fair to net it against the price. What you should not do is proceed on a verbal promise that the seller will settle it later, because once the property is yours the leverage is gone.

How does this fit the rest of your resale due diligence?

Property tax is one strand of the dues check that a resale buyer must run in full. Alongside it sit the maintenance dues to the association, any pending utility bills, and the khata and registration readiness of the flat. Each is a place where a previous owner's neglect can quietly become your bill. Running them together, early, is what turns a resale purchase from a leap of faith into a set of boxes you have actually ticked.

A well documented development, for instance Embassy Biome in Yelahanka, is the kind of project where tax and khata records for each unit should be traceable, and that traceability is exactly what you are testing for in a resale.

One last habit is worth building once you own the flat. Keep paying the property tax on time each year and keep your own receipts, because the same problem you just avoided as a buyer is the one you can accidentally create for your own future sale. A clean, unbroken tax history is quietly one of the most saleable features a resale flat can have, since the next buyer will run exactly the check you just ran. Protecting your record protects your eventual resale, and it costs nothing more than paying a bill the state was going to charge you anyway.

Your seven step property tax verification checklist

1. Ask the seller for the property identification number and the SAS application number.

3. Confirm the current year property tax is fully paid.
4. Check specifically for any accumulated arrears from earlier years.
5. Collect the last three years of paid receipts and match the PID and owner name.
6. Make clearance of all dues up to the sale date a written condition on the seller.
7. Hold back part of the payment until an updated paid receipt confirms a clean account.

Frequently asked questions

Do unpaid property taxes transfer to the new owner in Bengaluru? Yes. Property tax is a charge on the property, so unpaid BBMP tax stays attached to it and passes to the buyer. A clean sale deed does not remove this liability, which is why you should verify the tax account and demand cleared dues from the seller before paying any advance.

How do I check BBMP property tax dues before buying? Visit bbmptax.karnataka.gov.in and search using the property identification number or the SAS base application number, or by owner name if needed. The portal shows the tax paid last year and the amount due this year. Check for both current dues and any older arrears carried forward.

Can property tax arrears stop my registration or khata transfer? Yes. BBMP checks property tax status at the khata transfer stage, and outstanding arrears stop the transfer until cleared. At registration, the sub registrar requires the latest tax paid receipt, and unpaid tax can delay or prevent the sale deed from being registered.

How many years of tax receipts should I ask the seller for? Ask for the last three years of property tax paid receipts before paying any advance. Three years reveals a payment pattern rather than a single receipt, and it aligns with what registration and transfer offices expect. Match the PID and owner name on the receipts against the portal and the sale deed.
