How do I register to collect sales tax in Iowa?

You can apply or register for an Iowa sales tax permit by visiting the Iowa Department of Revenue and following the instructions provided.

Iowa also has an old school paper based form (PDF) you can print and mail in, but this is going to be a slower setup and with greater possibility for errors. We don’t recommend it, but wanted to make the option available in case it suits the needs of someone out there.

Iowa charges precisely zero dollars and zero cents for a business to register to pay sales tax :) 



Do I need a Federal Tax ID Number or EIN to register for an Iowa sales tax permit?

You’ll want to give this some thought and do a little research or investigating; since every business is unique, and there are such different rules, regulations, and laws that may apply.

Iowa Sales Tax FAQ

Iowa Sales Tax FAQ 


By now, you may have already contacted the Iowa Department of Revenue and applied for an Iowa sales tax permit. 

Once you have a license to collect and remit sales taxes in Iowa, you will probably be asking yourself two questions: 

  • When do I charge a sales tax in Iowa?
  • What goods and services are subject to sales taxes in Iowa? 

We are going to go over some common questions that our clients have asked. We believe these questions will help you appreciate the nuances of taxable goods so you can be confident in fulfilling your tax obligations. 

Let’s start with the first question…



What goods and services are considered taxable in Iowa?

The following items are all taxable in the state of Iowa: 

  • Sales of tangible goods at retail.
  • Repairs or alterations of tangible personal property.
  • Property rentals, leases, or licenses [e.g. commercial, mini-warehouse]
  • Selling service warranty contracts.
  • Short-term rentals for living accommodations (e.g. motel/hotel, beach houses, condos, timeshares, vacation homes, or RV homes).
  • Rental/lease of personal goods (e.g.: machinery, vehicles, equipment, or other property).
  • Charges for admission to any place of amusement, sport, or recreation.
  • Manufacturing or producing goods for retail sales.
  • Operating vending machines or amusement rides.
  • Services are mostly exempted... mostly.


The bottom line is …

Your business must pay taxes on sales of any non-exempt goods, and some taxable services.



Let’s now review some of our clients’ frequently asked questions:

  • Is Iowa an Origin or Destination sales tax State?
  • What creates a sales tax nexus in Iowa?
  • What is the economic threshold in Iowa?
  • Does Amazon have fulfillment centers in Iowa?
  • Does Iowa have a Click-Through Nexus?

To best understand your tax obligations, new businesses need to consider how they are doing business and the type of relationships they have with buyers and any third parties to their transactions. 

 Let’s discuss some questions that will help you understand the nature of your small business and the subsequent tax implications.   



Is Iowa an origin or destination-based sales tax state?

Iowa is a destination-based sales tax state, which simply means you charge sales tax based on the location of the purchaser rather than that of the seller. Local cities and unincorporated areas may choose to add an additional 1%. Iowa’s Department of Revenue offers a website to check the sales tax rate based on an address.


 Protip: Charge the customer tax based on their location.


What creates a tax nexus with the state of Iowa?  

Having nexus, also known as "sufficient business presence,” with Iowa means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Iowa because you created a sales tax Nexus.

Even if your business maintains its main headquarters in another state, you may still have to charge and pay sales tax to the Iowa Department of Revenue even if you never step foot in Iowa.   

So, how do you create a sales tax nexus in Iowa?


A business establishes a nexus in Iowa by:

  • having a business location in Iowa;
  • having property stored in Iowa;
  • employing any person in Iowa;
  • contracting with a salesperson or other agent in Iowa;
  • leasing equipment used in Iowa;
  • performing services in Iowa;
  • licensing the use of intangible property in Iowa, or transporting property in Iowa using the taxpayer’s vehicles.

Let’s talk a bit more specifically about where your goods are stored such as in the instance of an Amazon warehouse. 



Does Amazon have fulfillment centers in Iowa?

No, Iowa has no distribution centers at this time.

This information is relevant for our customers who sell products on Amazon or are recognized as Amazon FBA (Fulfillment by Amazon) sellers. When Amazon stores products in one of its fulfillment centers in any state including, it triggers a sales tax requirement. 



Does Iowa have economic nexus?

Yes, Iowa now has an economic nexus law. As of January 1st, 2019 remote sellers are liable to pay sales tax beyond a certain threshold. This means even businesses without a physical presence or traditional nexus can be required to register for, collect, and pay sales taxes.

The threshold for registering is having a cumulative gross revenue of over $100,000 to Iowa purchasers. Other states include a separate transaction number, but not Iowa.

For  more information see the Iowa DOR’s remote sellers page here. They also have a separate page with filing info for remote sellers and marketplace facilitators.



Does Iowa have click-through nexus?

Yes, Iowa has click-through nexus as of January 1st, 2019. This means if your business is involved in affiliate marketing sales to Iowa purchasers, you may be liable to pay sales tax even if you aren’t located in the state of Iowa. 

If you are a seller selling on a marketplace, and the marketplace collects Iowa sales tax, you do not need to register. In any other situation where your business is garnering revenue from assisting sales and gross receipts exceed $100,000/year, you will need to register and pay as a marketplace facilitator. Iowa’s Department of Revenue has more information and clarity on marketplace facilitators here. They also have a separate page for filing info for remote sellers and marketplace facilitators.



Is Iowa a streamlined sales tax state?

Yep! Since October, 2005 Iowa has been a full member of Streamlined Sales Tax.

If you are planning on taking advantage of the Streamlined Sales Tax as a business, it is recommended you use a Certified Service Provider though businesses may opt to register themselves without a CSP. Ultimately the aim of streamlined sales tax is to simplify payment to multiple different states of sales and use tax. It isn’t required that you utilize them, but it can significantly reduce complexity to do so, especially if your business sells in multiple states.


More effectively manage your tax needs by keeping this guide handy. 

You and your business can be better equipped to avoid situations like paying fines, paying back taxes that you did know you had to pay in the first place, or facing an audit by the tax authorities in Iowa.



Collecting sales tax in Iowa

Collecting Sales Tax in Iowa


By now you know if you are a business that has established a nexus with Iowa. So you have an understanding about whether, and when, you are required to collect sales tax. Knowing this is just half the battle! Now, we are going to help you with the next half of the battle: how to navigate the process of collecting taxes.

Let’s review some common questions our clients have asked regarding their Iowa Sales Tax obligations. 

  • How do I collect Iowa Sales Tax?
  • Who is eligible for Iowa Sales Tax exemptions?
  • What should I do if my customer is exempt from sales tax in Iowa?
  • What happens if I lose an Iowa nontaxable transaction certificate? 

After reading this, you will be better equipped to determine when --and when not-- to collect sales tax in Iowa.



How do I collect Iowa sales tax?

Iowa is one of those few states that mandates tax be collected from customers at transaction time. You may not ‘absorb’ the tax and must convey it distinctly in the receipt if doing so. As we covered earlier, Iowa is a destination-based state, so you’ll want to collect tax based on the purchasers location. Your point-of-sale software should make this relatively simple, including accounting for any local surtaxes



What are the current Iowa sales tax rates?   

Iowa’s state-wide sales tax rate is 6% at the time of this article’s writing, with the local surtaxes potentially bringing that as high as 8%. However, since sales tax rates may change, we shall refer you to check out the Iowa Department of Revenue tax rate lookup page. Any change will be reflected on that page.

It always helps to be accurate and up to date with this type of information! :) 



What is exempt from Iowa sales tax?

Here is a sample list of exemptions: 

  • purchases for resale
  • Everyday clothing items
  • Medical supplies
  • Groceries 

Iowa has too many exempt items to list here, but they go into greater detail on their website.



Who are eligible for Iowa tales tax exemptions?

At this point, you should know what products are exempt from sales tax in Iowa. You also want to know who may be exempt. 

Under Iowa law, the type of buyer or the way the goods will be used can qualify can buyer for a sales tax exemption. A good example of this is a merchant purchasing goods for resale, aka a wholesaler.

Other common examples of an exempt buyer may include:

  • Government agencies
  • Non-profit organizations
  • Religious groups
  • Out-of-state buyers (should their business not have nexus in their home state).

Note that a non-profit or contractor status doesn’t necessarily immediately confer tax exempt status. To learn more about tax issues for non-profits in Iowa, click here.



What should I do if my customer is exempt from sales tax in Iowa?

Purchasers who are tax exempt must have completed form 31-014 (PDF) and must present their completed exemption certificate at the time of purchase. It is then incumbent upon you, the seller, to hold on to this exemption certificate. Failure to do so may leave you unable to justify tax exempt sales.

Remember, you always want to collect and file a copy of the exempt certificate. Such certificates must be produced upon request in the event of an audit to justify tax-exempt sales.



What happens if I lose an Iowa sales tax exemption certificate?

Hmm... Obviously this issue is best to be avoided! Imagine finding out you’ll be audited and discovering you cannot produce an exemption certificate for a buyer! That nightmare scenario would mean you could be held liable to pay all taxes on behalf of the buyer. This is a bad scene and can be avoided by taking proper care with your paperwork… which happens to be one of our specialties! :) 



Does Iowa have a sales tax holiday?

Yes, they do! 🎉🥳 The tax man takes a brief rest in Iowa each year on the first Friday and Saturday in August. Items of clothing under $100 are exempt from sales tax during the holiday. For more information, check out the Iowa Department of Revenue Tax Holiday page.




We have now covered who you need to collect sales taxes from, how to determine whether goods for sale are deemed taxable, what goods and services fall under tax exemptions, who is eligible for tax exemption certificates, and, finally, the process of collecting sales tax in Iowa state. 

Now that we’re this far down the rabbit hole there’s only one thing we need to learn about next… how to pay the piper!
