Online guest payment

Curious about online payment but tired of juggling passwords? Keep reading.

You can pay your Alliant Energy bill online without setting up an account or password. It’s called online guest payment.

Just like writing a check, you choose the amount you pay and when to pay it. Unlike writing a check, you get instant confirmation that your payment was received, and there’s no delay time in the mail.

You choose whether the payment comes from your bank account or a credit card (no fees).

Myths about online payment

Have any of these myths kept you away from online payment? If they have, it may be time to give online bill pay another look.

Myth #1. To pay my Alliant Energy bill online, I’ll have to set up another password.

THE TRUTH: Another password is the last thing anyone needs. That’s why you can make a guest payment online without a password. All you need is your Alliant Energy account number, which is on your bill.

Myth #2. Online payment isn’t safe.

THE TRUTH: Most identity theft starts with physical documents, including lost or stolen mail. With online payment, there’s no physical mail to intercept.

Myth #3. If I pay online, I’ll stop receiving my paper bill.

THE TRUTH: Making an online payment won’t cancel your paper bill. If you’re getting a paper bill now, you’ll keep getting it – regardless of how you pay.
