Yes, however we DO NOT recommend paying your taxes this way, especially towards the end of any month, as the envelope that the checks are mailed in DO NOT have a USPS postmark. Since CT General State Statute states "No tax or installment thereof shall be construed to be delinquent...if the envelope containing the amount due..., bears a postmark showing a date within the time allowed by statute for the payment of such tax or installment.", we will process the checks using the interest date of the day that the payment was received. Any other payments made by mail that are received with envelopes that do not have a USPS postmark will be processed in the same manner. Exception: Envelopes that are postmarked on time, but include payments that are postdated past the last day to pay will be processed with applicable interest.
