Supplemental Savings FAQs

What’s the difference between a regular savings account and the supplemental savings account?

The only difference is that a supplemental savings is an additional savings account. You can name each account based on your specific financial goals — saving up for a vacation, making a large purchase, etc. — allowing you to more easily track your progress toward that goal.

Can I have more than one supplemental savings account?

Yes. You can have up to 19 supplemental savings accounts.

Do I have to maintain a minimum balance to have a savings account or to earn interest?

The minimum balance to keep your savings account open is $5. To earn interest, you must maintain a daily average minimum balance of $100. Alliant interest is paid monthly.

Are there any transaction restrictions for savings accounts?

The number of withdrawal transactions from savings accounts are limited by federal law.

What is a preauthorized transaction?

A preauthorized transaction includes any arrangement with Alliant to pay a third party from your account upon verbal or written requests, including those received through the automated clearing house (ACH).

Why can’t I get a debit card for my savings account?

Savings accounts are a convenient way for members to save money. Federal regulations restrict the number of electronic transactions on savings accounts to six per month, excluding personal withdrawals. For this reason, we provide members a limited-use Convenience Card, which permits members to withdrawal cash from Alliant network ATMs. We encourage members to open a checking account for more flexible access to their money, while relying on a savings account for their money to remain and grow.
