How to get an Iowa Resale Certificate (Sales Tax Exemption Certificate)

An Iowa Sales Tax Exemption Certificate is a document that allows a business to purchase goods and services tax-free from suppliers for the purpose of reselling those goods and services. The tax certificate is also sometimes referred to as a “resale permit” or a “reseller’s permit.”

What is a Sales Tax Exemption Certificate?

When retailers purchase products to resell, they often don’t pay sales tax to the supplier on the purchase. The sales tax will still be paid, but instead of the retailer paying the state sales tax, the retailer charges sales tax to their customer on the final value of the merchandise. The collected sales tax is then sent by the retailer to the Iowa Department of Revenue.

For instance, when a lawn equipment dealer in Iowa purchases items like mowers, or parts from a manufacturer to sell in their dealership, by having a resale certificate, the dealer won’t pay sales tax on these transactions. When a homeowner farmer purchases a piece of equipment, the dealer will charge sales tax to the customer based on the full price of the item.

Throughout the course of business, the agricultural equipment dealer will accumulate sales tax from all their transactions with customers. Periodically, typically at the end of the month, the dealer will collect all the sales tax that has been charged to the customers and send it to the state of Iowa. In this way, the sales tax is effectively paid by the final consumer.

The purpose of the certificate is to provide evidence of why sales tax was not collected on a transaction. Similar names for a resale certificate include reseller number, seller’s permit, exemption certificate, wholesale license, or reseller’s license. In order for the supplier to allow the tax-exempt purchase, the seller needs proof the buyer intends to resell the product by providing a valid resale certificate.

The sales tax exemption is only intended to be used for inventory that will be resold and not intended for the tax-free purchase of items used in normal business operations such as paper, pens, etc.

Getting Started

Before a business starts selling products or providing taxable services, it must first get an Iowa Sales Tax Permit from the Iowa Department of Revenue. The Sales Tax Permit is sometimes referred to as a seller’s permit, sales tax number, or sales tax license.

Is a Sales Tax Exemption Certificate the same as a Sales Tax Permit?

The sales tax permit and Sales Tax Exemption Certificate is commonly thought of as the same thing, but they are actually two separate documents. The Sales Tax Permit allows a business to sell and collect sales tax from taxable products and services in the state, while the Sales Tax Exemption Certificate allows the retailer to make tax-exempt purchases for products they intend to resell.
