When using the online property tax payment option, there is a $.50 fee for all e-checks and a 2.15% fee for all credit card transactions. The vendor fees associated with credit card transactions and e-checks are passed along to the credit card or e-check users and are not paid by the Williamson County budget. Payments made using this service may take approximately 5-7 business days to post in our system and will show the date paid as the original payment date.
