Pay by Mail

When paying your tax bills by mail, please:  

  1. Write your BILL number(s) on the back of your check or money order
  2. Make the check or money order payable to "Tax Collector, City of Norwalk"
  3. Mail your payment to:  Tax Collector, City of Norwalk    125 East Avenue   Norwalk CT  06851  
  4. The last day to pay without interest  was Thursday, February 1, 2024.   We accept a postmark of February 1, 2024 or prior for timely payment.  If your payment arrives postmarked February 1, 2024 or before, it is considered ON TIME, regardless of when we receive it.   
  5. If your payment arrives after February 1, and is postmarked after February 1, or if it doesn't have a postmark, and arrives after February 1, it is LATE. THIS IS STATE LAW. 
  6. There has been an increasing amount of MAIL FRAUD in recent months.   If you are paying ANY BILL (including your tax bill) with a check, the US Postal Service recommends you NOT leave your payment in your own personal mailbox for pick up, because it can be STOLEN and tampered with.  The US Postal Service recommends payments containing checks should be deposited in a mailbox INSIDE the post office. 
  7. You may wish to pay by Electronic Check (E Check or ACH payment) to avoid this risk.  There is more information on this website, and on your tax bill, about this payment method. 

 If you are paying late, interest is charged at the rate of 1.5% per month, from the due date.  Please note the due date is July 1 or January 1 (not August 1 or February 1).  The minimum interest amount is $2.00 on each tax installment. There are no exceptions.  Interest is charged on all late payments regardless of the reason.   

Count the number of months from the due date (July 1, 2023, or January 1, 2024) until your payment date, and multiply that number by 1.5 for the proper percent.  For example: if paying a bill that was due July 1, 2023 in February 2024: 8 months (July through the following February, inclusive) x 1.5 = 12% interest.   A portion of a month is considered the equivalent of a month.  Interest is not charged per diem (by day).  There also may be other collection fees involved.  Additional motor vehicle collection fees, and lien fees on real estate accounts may accrue depending on when you pay.  Please call ahead or check online to see what you owe. 


 Warning about electronic bill payment / telephone bill pay services:  These services may not mail your payment when you expect them to!   You assume the risk of your payment arriving late if you choose to use these services.  These payments come to us without a postmark, and because of this, they must be RECEIVED  BY  US before the last day to pay (on or before February 1, 2024) in order to be considered timely.  Normally, the postmark controls, but if there is no postmark, timeliness depends solely upon our receipt of the payment.  

   Please read the instructions and warnings provided by your own bank before using any 'pay by phone' or electronic bill payment service.  Many service providers specifically advise NOT to use the service for tax payments for the reasons given.   If you chose to use one of these services. we suggested your transaction should  have been processed before January 17, 2024, to attempt to ensure your payment reached us by the February 1, 2024 deadline.
