After reading this, you’ll know:

Do you have sales tax nexus in Iowa?

Good news! You only have to begin thinking about Iowa sales tax if you have sales tax nexus in Iowa.

“Sales tax nexus” is just a fancy way of saying “significant presence” in a state.

Iowa considers a seller to have sales tax nexus in the state if you have any of the following in the state:

  • An office, warehouse, distribution house or place of business
  • An employee, contractor or other representative in Iowa, either temporarily or permanently
  • Installs property it sold in Iowa
  • A construction contractor performs a job in Iowa
  • Regularly engages in delivery of products to Iowa

Is what you’re selling even taxable?

You’ve probably read this far because you realized you have sales tax nexus in Iowa. Your next step is to determine if what you’re selling is even taxable.

Services in Iowa are generally not taxable. So if you’re a freelance writer or a plumber, you’re in luck and you don’t have to worry about sales tax. But watch out – if the service you provide includes creating or manufacturing a product, you may have to deal with the sales tax on products.

Tangible products are taxable in Iowa , with a few exceptions. These exceptions include certain foods and items used in agriculture or manufacturing. You can see a list of tax-exempt items in Iowa here.

So if you sell musical instruments, then charge sales tax to your Iowa customers.

But if you’re a piano teacher, don’t charge sales tax to your Iowa customers.

If you have sales tax nexus in Iowa and your products are taxable, your next step is to register for a sales tax permit.

How to Register for a Sales Tax Permit in Iowa

Sellers with sales tax nexus in Iowa must apply for an Iowa sales tax permit.

Don’t skip this step! Many states consider it unlawful to collect sales tax in their name without a permit. Go here for more on how to register for a sales tax permit in Iowa.

How to Collect Sales Tax in Iowa

So you’ve determined that you have sales tax nexus in Iowa and what you’re selling is taxable. And you’re all set and registered for your Iowa sales tax permit.

The next step is to determine how much sales tax to collect.

Iowa is a destination-based sales tax state. If your business is based in Iowa, you would charge sales tax at the rate of your buyer’s ship-to location.

Example: You live and run your business in Iowa City, IA where the sales tax rate is the 6% state rate with no added local rates, but you sell to a customer in Dubuque, IA. The sales tax rate in Dubuque is made up of the 6% Iowa sales tax rate plus the 1% Dubuque County rate for a total of 7%. Since Iowa is a destination-based sales tax state you would charge your buyer the 7% sales tax rate due to where they are located.

But if you are not based in Iowa but happen to have sales tax nexus there for some reason, you are considered a “remote seller.” Remote sellers are only required to collect “use tax.” (Use tax is similar to sales tax, but collected by out-of-state sellers.) Iowa’s use tax rate is a flat 6%.

You can look up your local sales tax rate by going to TaxJar.com/mobile on your mobile device or look up any sales tax rate by zip code by going to with TaxJar’s Sales Tax Calculator.

Should you collect sales tax on shipping charges in Iowa?

As long as you separately state the shipping charges on your bill to your customer, you do not have to charge sales tax on shipping.

But if you include shipping in the price of the product you sell the customer, then shipping is considered part of the taxable transaction and Iowa declares that you must collect sales tax on shipping.
