Our Travis Quick-Pay service allows you to make a loan payment or credit card payment using a debit card, or your checking or savings account. Your property tax bill is due on January 31. After you pay your bill to your local tax office, funds are distributed to your taxing entities. How do I use credits? How do I recharge my credit balance?
