DES MOINES, Iowa — More than 33,000 Des Moines Water Works customers will be getting a small refund on their next bill.
The Des Moines Register reports Water Works was collecting tax on a voluntary $3.99 monthly fee for the waterline service maintenance program called HomeServe.
The tax first showed up in spring 2013.
The state received $105,675 of unlawful taxes paid by 33,338 people.
A complaint from a customer prompted an inquiry.
Water Works stopped collecting the sales tax in October.
Customers don’t have to do anything. They’ll receive a credit of between 24 cents to roughly $4.50 on their next bill.
