Water Tax Online Payment Receipt: How to Pay Chennai Metro Water Tax and Download the Receipt

Shop owners, landlords and small businesses in Chennai pay water tax and water/sewerage charges to the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB), commonly called Chennai Metro Water. Paying online takes a few minutes, but many people struggle afterwards to find the water tax online payment receipt, especially when a bank, a tenant, a buyer or a licensing authority asks for proof.

This guide explains how to pay online, how to download the receipt, and what to do if the payment went through but the receipt did not.

Quick answer: Pay Chennai water tax on the official CMWSSB portal (chennaimetrowater.tn.gov.in) or through Bharat BillPay-enabled apps, using your consumer number / CMWSSB account number. The receipt is generated immediately after payment and can be downloaded again later from the portal's payment history or duplicate receipt option by entering your consumer number.

What Is Water Tax in Chennai?

Property owners in the CMWSSB area are billed for:

1. Water tax, linked to the property's annual value, and
2. Water and sewerage charges, based on the connection and, where metered, consumption.

These are billed half-yearly for most properties. Commercial and industrial connections often have different tariffs from residential ones.

Chennai Water Tax Online Payment: Steps

Option 1: CMWSSB portal

• Visit chennaimetrowater.tn.gov.in.
• Choose the online payment option for water tax and charges.
• Enter your consumer number (or CMWSSB account number) as printed on your previous bill or receipt.
• Check the owner name, property address and amount due.
• Pay through net banking, debit or credit card, or UPI.
• Save or print the receipt shown on the confirmation screen.

Option 2: Bharat BillPay apps

CMWSSB payments may be available through Bharat BillPay on banking and UPI apps. Search for the biller name, enter your consumer number and pay. The app gives a transaction reference; for an official receipt, download it from the CMWSSB portal afterwards.

Option 3: Offline

Pay at CMWSSB area or depot offices, or authorised collection centres. Ask for a computer-generated receipt.

CMWSSB Receipt Download

To get the water tax online payment receipt again:

• Open the CMWSSB portal.
• Go to the payment history / duplicate receipt / print receipt option.
• Enter your consumer number (and, where asked, the transaction date or reference number).
• Download the PDF receipt.

Save the receipt with a clear file name such as "CMWSSB-[consumer no]-[half-year]-receipt.pdf". Businesses should keep these receipts for at least eight years along with property tax receipts.

Water Tax Payment by Consumer Number: Where to Find It

Your consumer number appears on:

1. An earlier water tax bill or demand notice
2. A previous payment receipt
3. Your connection documents from CMWSSB

If you have lost all of these, visit the CMWSSB area office with your property tax receipt and ownership proof to retrieve it.

Payment Done but Receipt Not Generated

• Wait 24–48 hours. Bank confirmation sometimes takes time to reflect.
• Check your bank statement for the debit and note the transaction reference.
• Try the duplicate receipt option on the portal.
• If not updated after 3 working days, raise a complaint with CMWSSB customer care or visit the area office with the bank statement.
• If the payment failed but money was debited, banks usually reverse it within 5–7 working days.

Water Tax Due Date and Penalty

Water tax and charges are generally payable in each half-year. Late payment can attract a surcharge or penalty as per CMWSSB rules, and long overdue amounts may lead to disconnection notices. Check the due date on your demand notice or on the portal, as it can vary by billing cycle.

Water Tax Name Change

After buying a property, the CMWSSB records must be updated to the new owner's name:

• First update the property tax records with the Greater Chennai Corporation.
• Apply to CMWSSB with the sale deed, updated property tax receipt, ID proof and the latest water tax paid receipt.
• Follow the online name transfer option if available on the portal, or apply at the area office.

Clear all dues before applying, as name transfers are usually processed only for accounts without arrears.

Why Businesses Need the Water Tax Receipt

For GST registration, the principal place of business proof is usually an electricity bill, property tax receipt or municipal khata copy. A water tax receipt can serve as supporting evidence of ownership or occupation.
