The total tax payment is due by January 15th. If payment is postmarked after January 15th penalties accrue on the following dates: January 16, February 2, and March 17. 

1. In person, at the Lexington County Treasurer's Office, with cash, check (payable to County of Lexington), or debit/credit card. Convenience fees apply to all tax payments made with a credit or debit card.
2. Online with a debit/credit card or electronic check. Convenience fees apply to all tax payments made with a debit/credit card or electronic check.
3. Through the mail with check only. Make check payable to County of Lexington, include tax bill, and write the bill number on the check. The United States postmark is the determining date for mailed payments as to whether or not penalty applies.
4. At the Lexington County Treasurer's Office night deposit box for convenient after business-hours payment. Checks only, made payable to the County of Lexington, include tax bill and write the bill number on the check. The night deposit box is located in front of the County Administration Building.
If your payment cannot be processed, it will be returned for the necessary corrections. Additional penalties and/or fees may accrue. Failure to receive a bill does not exempt the account from penalty. The Lexington County Treasurer's Office is not responsible for mail that has been mishandled by the US Postal Service. 

These numbers make it possible to process your payment more efficiently. The numbers are a code that can be read by an optical scanner thereby automating the receipt of your payments paid by mail.
