Iowa Sales Tax

As a retailer making sales to customers in Iowa, you need to be aware of the state’s sales tax regulations in order to understand how they may apply to you. Any retailer based in Iowa must collect and remit sales tax to the state, and some out-of-state retailers do as well, depending on whether or not a nexus condition exists. Of course, you only have to pay sales tax if what you’re selling is taxable, and if you do have a nexus, you need to know what rates to charge your customers.

Iowa Sales Tax Rates

The Iowa sales tax is a combination of a state rate and a Local Option Sales Tax (LOST). The total sales tax rates paid at different locations are made up of:

• Iowa (IA) State Sales Tax Rate: 6.0%
• Local Tax Range: 0% to 1.0% (Most local jurisdictions apply the 1% LOST)

Therefore the maximum combined rate at any given location is 7.0%.

Tax Sourcing

Iowa is a Destination-Based Sourcing state.

• General Rule: Sales are sourced to the location where the customer receives the product.
• In-State: If you ship from Des Moines to a customer in Cedar Rapids, you apply the Cedar Rapids (Linn County) rate.
• Over-the-Counter: If the buyer takes possession at your place of business, the sale is sourced to your business location.

Iowa Nexus

Most business owners with a physical presence in the state of Iowa will have sales tax obligations, but many remote sellers do as well. Read on to find out how to determine what kind of Iowa sales tax nexus your business has.

Physical Nexus

You will be considered to have a nexus in the state for sales tax purposes if you:

• Have a physical business location in the state
• Have employees or independent contractors coming into Iowa to perform business-related activities other than solicitation of orders
• Store goods in a warehouse in the state

Economic Nexus

Iowa’s economic nexus law is similar to most other states, with a threshold of $100,000 in gross revenue made within Iowa by out-of-state sellers. Economic nexus threshold is computed based on total sales during the preceding calendar year.

Marketplace Facilitators

Marketplace facilitators (Amazon, Etsy, etc.) are required to collect and remit Iowa sales tax if they facilitate more than $100,000 in Iowa sales.

Reporting: Marketplace sellers should include marketplace sales in their “Gross Sales” on the Iowa return, but then deduct them as “Sales to Marketplace Facilitators” to avoid double-paying.

If you’re unsure whether your business is considered to have a sales tax nexus in Iowa, the state provides a questionnaire you can fill out to have a final determination made.

Iowa Use Tax

When Iowa customers buy taxable goods and services from retailers who are not subject to sales tax collection in the state, they owe the amount that would have been collected as use tax. Click here for more information on use tax.

What is Taxable in Iowa

Tangible Goods

Most physical products are taxable at the 6% state rate plus local options.

Exemptions: Unprepared groceries, prescription drugs, and certain chemicals used in agriculture/manufacturing.

Services

Iowa taxes a long list of “enumerated taxable services,” including:

• Digital Support: Installing or repairing computer software.
• Maintenance: Janitorial and landscaping services.
• Personal: Photography, barber/beauty services, and tanning.

Other services not in Iowa’s official list are likely non-taxable.

Shipping and Handling

Delivery and shipping charges are generally exempt in Iowa if they are separately stated on the invoice and are not part of the “sales price” of the item.

Digital Goods

Digital Products: E-books, digital music, and streamed movies are taxable in Iowa.

SaaS: Software as a Service is generally taxable as an “enumerated service” (specifically under “Software as a Service” or “Computer Software”). However, there is an exemption for SaaS used “exclusively” by a commercial enterprise.

Exempt Buyers

Certain buyers may be exempt from sales tax depending on who they are and how the item will be used. The following list is a general guide to the applicable Iowa law:

• Federal, state, county, and municipal government agencies are exempt on direct purchases
• Certain non-profits organizations are exempt, including hospitals, educational institutions, residential care facilities, mental-health centers, museums, and zoos.
• Churches and religious institutions are exempt only for purchase of items used directly for religious or educational purposes.
• Manufacturing, processing, fabrication, and agricultural production companies have broad exemptions
• Companies buying for resale and wholesale purposes who provide a resale certificate

To apply for a sales tax exemption certificate use form 31-014.

Sales Tax Holidays

Annual Sales Tax Holiday (August 7–8, 2026): Iowa holds its annual tax holiday on the first Friday and Saturday of August.

• Exempt Items: Clothing and footwear with a sales price of less than $100.

Note: This holiday applies to both state and local option taxes. Accessories (jewelry, handbags) and athletic equipment remain taxable.

Registration and Filing

Before you can begin making taxable sales to your customers in Iowa, you will have to register with the state to collect and remit sales tax. This can be done online or by mail, and there is no charge, although a bond may be required if you or a partner in your company has a history of delinquent payment. You will need to obtain a separate permit for each business location you operate in the state.

Iowa is a member of the Streamlined Sales and Use Tax Agreement (SSUTA), so you can also register to collect and remit Iowa sales tax through that organization’s website. However, when you register with the SSUTA, you will be required to register in all member states simultaneously. This may or may not make sense for you depending on the number of states where you currently do business or where you’re planning to in the near future.

You can file your sales tax return online or by mail, and Iowa does require zero returns, which means that, as long as you hold a valid sales tax permit in the state, you will have to file a return whether or not you made any taxable sales during the period in question.

Filing Frequencies and Deadlines

At the time of your registration, the state will assign you a filing frequency based on your anticipated sales volume. This can be adjusted up or down annually as well if your sales volume changes over time. In general, you will file:

• Annually if your sales tax liability is less than $1,200 per year
• Monthly if your sales tax liability is $1,200 or more per year

For annual filers, your Iowa sales tax return and payment will be due on January 31st of the following year.

Iowa changed their filing periods for filing periods effective July 1, 2022 There are only annual and monthly filing periods now, depending on if your sales tax liability is more or less than $1,200. All payments are made via GovConnectIowa or by paper.

Penalties and Interest

If you are late filing your return and at least 90% of the tax due has not been paid by the due date, you will incur a penalty of 5% of the total tax due. If your return is filed on time, but you have not remitted at least 90% of the tax due by the due date, a penalty of 5% of the total tax due will be charged to your account. You may be subject to both fees, if both are applicable. This supersedes a previous rule and is documented here.

Interest charges will be added to outstanding balances as well at varying rates, and it accrues monthly. The rates can be found at the link above.
