What are the benefits of having an Alliant Teen Checking Account? An Alliant Teen Checking Account is a great way for teens to learn about and practice financial management. The teen account offers many of the same benefits as our regular Alliant Checking account, including online banking, mobile banking, ATM rebates, High Rate Checking, and Overdraft Protection. Plus, the Alliant Teen Checking Account provides stricter access limits for debit card purchases and ATM withdrawals. Note: Parent/guardian must set up overdraft protection on a free teen checking account. Learn more about Alliant Teen Checking.
