In 2018, the Iowa legislature enacted Senate File 2417, a state tax reform bill that includes extensive changes to the state’s tax structure. Effective January 1, 2019, Iowa law began requiring marketplace facilitators to collect and remit Iowa sales tax and applicable local option sales tax for sales made or facilitated on the business’s marketplace. Generally, a marketplace facilitator is a business that provides infrastructure or support for retail sales to occur and collects the sales price, processes payments, or receives compensation from the retail sale. One type of business that may qualify as a marketplace facilitator is a food delivery service company. If a business allows customers to order food and handles the payment for the customer, the business likely qualifies as a marketplace facilitator. This new guidance discusses this new aspect of the law and provides examples for a handful of situations.
