What is the KMC NOC in Kolkata?

Definition

The KMC NOC is the No Outstanding Certificate issued by the Kolkata Municipal Corporation, Assessment Collection Department, under the Kolkata Municipal Corporation Act, 1980. It confirms that the property carries no outstanding municipal tax dues for the period stated on the certificate.

For any KMC property transfer, the buyer must attach this NOC alongside Form A-42 mutation, the prescribed mutation application. Without the NOC, KMC will not accept the mutation, will not record the new owner, and will keep sending bills to the seller. The buyer continues to pay tax in someone else's name. Worse, the unpaid quarters silently transfer to the new owner. KMC has the power to issue stop-work notices and in 2024 began routing pending dues to new buyers through a clause in approved building plans.

The NOC is also asked for in many situations beyond mutation. Banks ask for it during home loan sanction. Sellers need it to show clean tax history. Some passport and visa applications also require a clean property tax record. The KMC issues it through a single dedicated computerised window at each Assessment Collection Unit (CMO Building, Tolly Tax, SSU, JU and GRU offices). The process begins with a Letter of Intimation that lists any outstanding dues. Once dues are cleared, the NOC is generated and handed over the same day.

State-specific note: The state warning is direct: for Kolkata, KMC NOC is essential and you must verify that property tax dues are cleared. Treat any seller refusal to produce the NOC as a clear sign of unpaid bills.

Common Issues With the KMC NOC in Kolkata

The NOC is a structured document; read every field before relying on it.

Old quarter dues hidden
The seller paid current bills but earlier quarters remain open. KMC adds those quarters to the new owner.
Fix: Pull the full Assessee history on kmcgov.in and clear every open quarter before signing.
Letter of Intimation not verified in 15 days
The LOI lapses; the counter will not generate the NOC without a fresh one.
Fix: Get the LOI verified by the Assessor-Collector inside the 15-day window; otherwise, restart the LOI cycle.
Builder dues passed to new owner
Promoters built the block while not paying KMC tax. Approved plans now carry a clause transferring liability to buyers.
Fix: Insist on a No Outstanding Certificate covering all quarters during construction before purchase.
Stop-work or attachment notice live
KMC has issued a stop-work notice for four-quarter default. Sale is risky.
Fix: Walk away unless the seller produces the satisfaction order in writing and a fresh NOC.
Wrong Assessee Number on NOC
The NOC carries an Assessee linked to a different flat or floor.
Fix: Get the NOC redrawn against the correct Assessee for the exact unit you are buying; the deed alone is not enough.
NOC expired before mutation filed
The buyer collected the NOC but delayed Form A-42; KMC rejects the file.
Fix: File the mutation within the validity window; if expired, apply afresh and clear any new quarter that has fallen due.

Why the KMC NOC Matters for Land Buyers in Kolkata

Within KMC limits, the NOC is the single document that severs the seller's tax history from yours.

📋
Cuts the unpaid-tax chain KMC bills run with the property, not the person
The NOC is what closes the seller's outstanding chain. Without it, every old quarter quietly becomes the buyer's problem.
⚠
Mandatory for KMC mutation The Kolkata warning is direct: KMC NOC is essential and property tax dues must be cleared
KMC will not accept Form A-42 mutation without the No Outstanding Certificate attached, full stop.
🏦
Bank loan and resale Lenders inside KMC limits ask for the NOC before sanctioning a home loan
Future buyers will too. A clean current NOC is the document that proves the property tax dues Kolkata residents must always clear are actually clear.
🔍
Kolkata-specific liability transfer KMC introduced a 2024 rule routing developer-era unpaid taxes to new owners through approved building plans
Outside KMC limits this clause does not exist. Inside the city, the NOC is the only firewall a buyer has.
Red flag: If the seller offers an old paid receipt instead of a current No Outstanding Certificate, walk away. Genuine sellers walk into the KMC counter and produce a same-day NOC. Old receipts hide quarters that quietly become your liability.
