What is the sales tax rate in Iowa?
Iowa’s statewide sales and use tax rate is 6%. Most jurisdictions add a 1% local option sales tax (LOST), bringing the common combined rate to 7%. The exact rate depends on the buyer’s location, so check the Iowa Department of Revenue for local details.
Do you have sales tax nexus in Iowa?
Nexus is the connection that obligates your business to collect and remit Iowa sales tax. You can establish it two ways — physically or economically. Either one is enough.
Physical nexus
You have physical nexus if you have a tangible presence in Iowa, such as:
- A physical place of business such as an office or warehouse
- Employees, independent contractors, or representatives working in the state
- Inventory or other property owned in Iowa
- Delivering goods in business-owned vehicles
Economic nexus
Out-of-state sellers establish economic nexus once gross sales into Iowa exceed $100,000 in the current or previous calendar year. Iowa originally also had a 200-transaction test, but removed that transaction threshold effective July 1, 2019 — so the test is now the dollar amount only.
What is taxable in Iowa?
Tangible personal property is generally taxable (with exceptions such as certain agricultural and manufacturing items), and — unlike many states — Iowa taxes a fairly broad list of services. Specified digital products are also taxable. Iowa publishes a detailed list of taxable services and exemptions on its website.
Is SaaS taxable in Iowa?
Yes — with an important exception. Iowa taxes SaaS for general/consumer use, but SaaS purchased by a commercial enterprise for use in its business is exempt. So B2B SaaS to a qualifying commercial enterprise generally isn’t taxed, while other SaaS is.
How is food taxed in Iowa?
Food products for off-premises consumption (groceries) are exempt. Retailer-prepared food for immediate consumption, candy, and certain beverages are taxable.
How to register for an Iowa sales tax permit
You need a sales tax permit (one per Iowa business location) before collecting. Taxually can register for you, or you can apply online through GovConnectIowa (or by mail/fax using the Iowa Business Registration form). There is no fee.
Keep the permit readily available for verification, though you’re not required to display it.
How to collect sales tax in Iowa
Iowa is destination-based — charge the combined state-plus-local rate for the buyer’s Iowa location. Remote sellers with nexus collect exactly as in-state sellers do.
Filing and paying Iowa sales tax
Filing frequency depends on annual tax: annual (less than $1,200/year), due January 31 of the following year; or monthly ($1,200 or more), due the last day of the month following the period. A seasonal option exists for businesses that collect in four or fewer months a year.
File and pay online through GovConnectIowa. Taxually’s software automates the full process.
Penalties for late or non-compliant filing
Failing to file or pay on time triggers these penalties:
- Failure to file: 5% of the tax due.
- Failure to pay: 5% of the unpaid tax.
- Interest accrues on unpaid tax at the current rate (set annually).
