Late Payment/Warning

If you pay delinquent motor vehicle tax bills online or in person, you will NOT be able to register/renew registration at CT DMV for up to 48 hours from the time of payment. Do NOT pay delinquent motor vehicle tax bills on this site and expect to conduct DMV registration business on the same day. An electronic report is sent to DMV every evening listing all taxpayers that are clear to register. This is a Town of Southington policy and exceptions will not be made.
Make online payment

A payment that is mailed and bears a legible US Postal Service (USPS) postmark of August 1, 2024 will be considered on-time. The stamp of metered mail through a service such as Pitney Bowes, Neopost, or does not constitute a USPS postmark. Any payment received after August 1, 2024 solely bearing such a stamp will be considered late.

LATE PAYMENT WARNING when using a Bank Payment Service like "Bill Pay" - You should be aware that bank payments via a paper check electronically drawn from your bank account (e.g. savings, checking) and mailed to the Tax Collector's office must meet the same postmark requirements mentioned above. The date on the paper check is meaningless. Furthermore, you should know that we receive many envelopes from banks with "bill pay" checks without a valid USPS postmark. Any payment received after August 1, 2024 without a postmark will be considered late. Finally, most banks require that you schedule your payment 5 business days before their "deliver by" date. Using August 1, 2024 as the due date, means a bank expects you to schedule payment on or before July 25th. Waiting until July 25th or later to use a "bill pay" service is a dangerous practice and a potentially expensive late payment and interest experience for the taxpayer.
