Wyoming Sales Tax Guide

Wyoming Sales Tax Guide

Wyoming, the Equality State, is the final state in our series on sales tax. It gets its nickname, in part, from a storied history of being the first state to give women the right to vote.

You need not fret as this is a relatively simple process and one for which you’re about to be fully prepared. We are going to outline the steps below so you are totally ready to register for your sales tax license.


Here we go! Remember...

Preparation is key. 

Let’s get started!


How do I register to collect sales tax in Wyoming?

You can apply or register for a Wyoming sales tax permit by visiting the Wyoming Internet Filing System (WYIFS) site and following the instructions provided.

Wyoming prefers online registration but offers an old school paper-based form (PDF) you can print and mail in. We suggest that new businesses who are able to do so register online, as the mail-in version takes longer to process.


What information do I need to register for a Wyoming sales tax permit?

Great question!

Before you sign up for a Wyoming sales tax permit you’ll want the following information on hand:

  • Business name
  • Business entity type 
  • Description of business activities
  • Date business activities began or will begin
  • Business address and mailing address
  • Business contact information
  • Associated business entities 
  • NAICS code that best matches the business
  • Federal Employer Identification Number (FEIN)
  • List of business officers, partners, managing members, and/or trustees

Don’t forget! Preparation is key. When you have all this information ready, you can go online and register for your permit at the WYIFS site


How much does it cost to register for a Wyoming sales tax permit?

Wyoming charges $60 to register a new business sales tax permit, but nothing to renew an existing one.


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

Quite right! For anything but a sole proprietorship, you will most assuredly need one. If you don’t already have one and need to get a new EIN, it’s a painless process. You can register for a Federal EIN right here :). 


Which agencies in Wyoming do I need to additionally register with?

You may need to check with some of the following agencies or resources: 

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. 

We suggest contacting the Wyoming Department of Revenue to verify which additional government agencies you may be required to register with. 





You are now prepared to register for your Wyoming sales tax permit in Wyoming. 

Let’s summarize what we have covered:  

  • Have all the required information easily accessible before registering online.

Wyoming Sales Tax FAQ 


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

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

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

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 Wyoming?

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

  • Sales of tangible goods at retail.
  • Repairs or alterations of tangible personal property.
  • 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 exempt


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 Wyoming an Origin or Destination sales tax State?
  • What creates a sales tax nexus in Wyoming?
  • What is the economic threshold in Wyoming?
  • Does Amazon have fulfillment centers in Wyoming?
  • Does Wyoming 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 Wyoming an origin or destination-based sales tax state?

Wyoming 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 business location



What creates a tax nexus with the state of Wyoming?  

Having nexus, also known as "sufficient business presence,” with Wyoming means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Wyoming 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 Wyoming Department of Revenue even if you never step foot in Wyoming.   

So, how do you create a sales tax Nexus in Wyoming?


A business establishes a nexus in Wyoming by:

  • having a business location in Wyoming;
  • having property stored in Wyoming;
  • employing any person in Wyoming;
  • contracting with a salesperson or other agent in Wyoming;
  • leasing equipment used in Wyoming;
  • performing services in Wyoming;
  • licensing the use of intangible property in Wyoming, or transporting property in Wyoming 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 Wyoming?

None at this time, no.

This is relevant for our customers that sell on Amazon or through Amazon’s FBA program.

In such cases, we can help guide a small business through this regulatory maze! We use tools like A2X to identify where our clients' inventory is currently being held and shipped from so that we can keep them in compliance. 


Does Wyoming have economic nexus?

Yes! As of February 1st, 2019, 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 a cumulative gross revenue of over $100,000 or 200 transactions in a year to Wyoming purchasers. 

For more information see the Wyoming DOR remote sellers update here (PDF).


Does Wyoming have click-through nexus?

No, not at this time. This means if you earn revenue by referring sales you do not have to worry about an extra tax hit [for now].


Is Wyoming a streamlined sales tax state?

Yep! Since January 2008 Wyoming 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 the 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 Wyoming.



Collecting Sales Tax in Wyoming


By now you know if you are a business that has established a nexus with Wyoming. So you have an understanding of 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 Wyoming sales tax obligations. 

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

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


How do I collect Wyoming sales tax?

Because Wyoming 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 Wyoming sales tax rates?   

Wyoming’s state-wide sales tax rate is 4% at the time of this article’s writing, but local taxes bring the effective rate up to 6% depending on the area. We advise you to check out the Wyoming Department of Revenue Tax Rate for 2020 (PDF) which has the current rates.

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


What is exempt from Wyoming 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 Wyoming. 


Who are eligible for Wyoming sales tax exemptions?

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

Under Wyoming law, the type of buyer or the way the goods will be used can qualify can buy 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 Wyoming?

Purchasers who are tax-exempt must have a complete exemption certificate (PDF) 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 Wyoming 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 Wyoming have a sales tax holiday?

Nope! No break from sales tax in Wyoming 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 Wyoming 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!

When is Wyoming sales tax due?

Wyoming sales tax payments are due based on the filing interval and type. Filing intervals are based on the company’s tax liability [detailed ahead, be patient! :p] and the type refers to paper vs. online.

The state of Wyoming requires payment by no later than the last day of the month following the reporting period for paper and electronic filing.


What are the Wyoming sales tax filing interval thresholds?

The thresholds for filing intervals are based on the expected or actual tax liability owed:

Average Tax Liability Owed Monthly*

Filing interval

From $0-$50


From $50.01-$150.00


From $150.01 and up



*anticipated if a new business, actual if an existing company


Not sure how to determine your tax filing frequency?

You can review your eCommerce or Point-of-Sale Software to see the volume of sales you have generated. 

Don't worry though! The state will let you know when your due dates change. :) 

Keep an eye out for notices in your mail from the State of Wyoming so that you don't miss any shift in deadlines.


What if a Wyoming sales tax filing date falls on a weekend or holiday?

The deadline is moved to the next business day, typically the Monday following the weekend or the day after the holiday. Where possible, we always suggest filing well before the holiday, of course ;). 


How do I file a Wyoming sales tax return?

Paper: Annual filers use form 42 (PDF) while monthly or quarterly use form 41 (PDF) and both mail to the address on the form. 

Electronic: File online via WYIFS site and submit payment via EFT.


How do I correct a Wyoming sales tax return?

Paper: Same forms as above but check “Amended Return” option on the first page, and mail to the address on the form.

Electronic: Amend the return within the WYIFS site.


What happens if I don’t collect sales tax?

If you were required to collect sales taxes and failed to do so for whatever reason, that’s a major no-no! Ultimately the business would be held liable for the due tax. Always be sure to collect sales tax at the point of sale. Attempting to collect after the fact will be time consuming and most likely unsuccessful. 


Protip: You are still responsible for remitting sales taxes even if you failed to collect them. 



What happens if I file or pay my sales tax return late?

Wyoming's Department of Taxation charges penalties for late filing and late payment:

Late filing instantly results in a $10 fine whether there is any outstanding payment to be made or not. Later than 30 days? Another $25 fine. 

Late payment results separately in a penalty of 10% of the tax due.


Do I need to file a return if I don’t collect any sales tax in Wyoming?

Yep! Wyoming requires businesses to file a “Zero-Tax” return even when they have no sales during a taxing period.


If I close my business, do I need to file a final sales tax return?

Yes, Wyoming requires businesses to file a “Final sales tax” return when closing their doors.


Does the Wyoming Department of Revenue offer a discount for filing on time?

Yes! On the first $6,250 of revenue, Wyoming offers a 1.95% “vendor discount” with a further  1% on the remainder up to a total of $500 per filing period! Definitely worth capitalizing on this by filing early :) 




Now that we have covered all our bases for filing and paying sales taxes in the state of Wyoming, you should feel more at ease about the process.


Some things to remember:

  • Due dates are important. If anything, file and pay your taxes early.

  • You can file and pay your taxes electronically or by mail
