Wisconsin Sales Tax FAQ
By now, you may have already contacted the Wisconsin State Department of Revenue and applied for a Wisconsin sales tax permit.
Once you have a license to collect and remit sales taxes in Wisconsin, you will probably be asking yourself two questions:
- When do I charge a sales tax in Wisconsin?
- What goods and services are subject to sales taxes in Wisconsin?
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 Wisconsin?
The following items are all taxable in the state of Wisconsin:
- 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.
- Most services are exempted
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 Wisconsin an Origin or Destination sales tax State?
- What creates a sales tax nexus in Wisconsin?
- What is the economic threshold in Wisconsin?
- Does Amazon have fulfillment centers in Wisconsin?
- Does Wisconsin 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 Wisconsin an origin or destination-based sales tax state?
Wisconsin is a Destination-based sales tax state. This simply means you’ll want to have your Point-of-Sales system configured to track sales tax based on your buyer’s location vs. that of your business.
Protip: Charge sales tax based on your buyer’s location rather than your location
What creates a tax nexus with the state of Wisconsin?
Having nexus, also known as "sufficient business presence,” with Wisconsin means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Wisconsin 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 Wisconsin State Department of Revenue even if you never step foot in Wisconsin.
So, how do you create a sales tax nexus in Wisconsin?
A business establishes a nexus in Wisconsin by:
- having a business location in Wisconsin;
- having property stored in Wisconsin;
- employing any person in Wisconsin;
- contracting with a salesperson or other agent in Wisconsin;
- leasing equipment used in Wisconsin;
- performing services in Wisconsin;
- licensing the use of intangible property in Wisconsin, or transporting property in Wisconsin 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 Wisconsin?
Yes, there is one Amazon fulfillment center in Wisconsin. Why does this matter?
This is relevant if you sell your products on Amazon or are recognized as an Amazon FBA (Fulfillment by Amazon) seller. When Amazon stores your products in one of its fulfillment centers in any state, including Minnesota, this triggers a sales tax requirement. If Amazon is storing your products in a warehouse in Minnesota, you have created a taxing connection with the state of Minnesota.
We can help guide your small business through this! We use tools like A2X and Wherestock to identify where our clients' inventory is currently being held and shipped from so that we can keep them in compliance.
Does Wisconsin have economic nexus?
Yes! As of October 1st, 2018, remote sellers are liable to pay sales tax beyond a certain threshold. This means that even businesses without a physical presence or other traditional nexus can be required to register for, collect, and pay sales taxes.
The threshold for registering is having over $100,000 or 200 transactions in a year to Wisconsin purchasers. Previously there was a minimum transaction threshold and a higher gross revenue requirement, but this was for a small window in 2019; starting 2020 only the revenue threshold will be required.
For more information see the Wisconsin DOR remote sellers page here.
Does Wisconsin have click-through nexus?
No click-through nexus laws on the books in Wisconsin as yet. This means that if your business makes revenue by referring sales AKA “affiliate marketing” you needn’t worry about a tax liability in Wisconsin.
Is Wisconsin a streamlined sales tax state?
Yep! Since October, 2009 Wisconsin 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 that 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 Wisconsin.
Collecting Sales Tax in Wisconsin
By now you know if you are a business that has established a nexus with Wisconsin. So you have an understanding about whether, or 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 Wisconsin sales tax obligations.
- How do I collect Wisconsin sales tax?
- Who is eligible for Wisconsin sales tax exemptions?
- What should I do if my customer is exempt from sales tax in Wisconsin?
- What happens if I lose a Wisconsin nontaxable transaction certificate?
After reading this, you will be better equipped to determine when --and when not-- to collect sales tax in Wisconsin.
How do I collect Wisconsin sales tax?
Because Wisconsin is a destination-based sales tax state, your business should charge sales tax at the time of the transaction based on the business location rather than that of the buyer.
What are the current Wisconsin sales tax rates?
Wisconsin’s state-wide sales tax rate is 5% at the time of this article’s writing, but local taxes bring the effective rate from 5.5% to 5.6% depending on location. We advise you to check out the Wisconsin State Department of Revenue Tax Rate page which has the current rate and links to lookup specific municipal rates. Any changes 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 Wisconsin sales tax?
Here is a sample list of exemptions:
- Non-prepared food
- purchases for resale
- Industrial Machinery
- Medical supplies
And that’s it! Most items of tangible property are taxable in Wisconsin.
Who are eligible for Wisconsin sales tax exemptions?
At this point, you should know what products are exempt from sales tax in Wisconsin. You also want to know who may be exempt.
Under Wisconsin 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 status doesn’t instantly confer tax exemption.
What should I do if my customer is exempt from sales tax in Wisconsin?
Purchasers who are tax exempt must have completed exemption certificate and must present their completed exemption certificate at the time of purchase. It is then incumbent upon 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 exemption certificate. Such certificates must be produced upon request to justify tax-exempt sales in the event of an audit.
What happens if I lose a Wisconsin sales tax exemption certificate?
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 of your paperwork... Which happens to be one of our areas of expertise! :)
Does Wisconsin have a sales tax holiday?
Nope! No break from sales tax in Wisconsin at this time. Boo!
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 Wisconsin state.
