Colorado Sales Tax Registration


Colorado Sales Tax Registration

Do you have to register for a sales tax license in the state of Colorado?

To know the answer to this question, you need to ask yourself another question first.

Do you sell tangible items?

If you replied “Yes,” congratulations! :) You get to register for a Colorado sales tax account.

Though it may sound like an arduous undertaking, it’s really not too big a deal, and you only need to do it once. Though it is worth keeping in mind: you will have to renew your registration every two years.

The fee to renew is a whopping $16, but the state makes it very simple. You can simply log in to your Revenue Online account, click on License Renewal, and follow the prompts to make the payment. Easy peasy.

If you prefer printing and mailing the renewal, you need to send in form DR 0594 before the due date. Remember to write “sales tax renewal” on the check or money order so that the funds are applied correctly.

The registration process is quite simple so long as you are prepared.

We will walk you through what you need to know:

  • How and where to register
  • What information is needed
  • Associated Costs
  • Other requirements such as a Tax ID or other agencies you may need to register with.

As our clients frequently ask about these topics, we will give you all the information you'll need to get started.

So, let’s get to it!


How do I register to collect sales tax in Colorado?

Before you get started, there are six sales tax licenses available. Let’s review each one so you can see which one you need to apply for.

  1. Standard Retail License (Sales Tax License)
  2. Wholesale License -
  3. Single Special Event License-
  4. Multiple Special Event License --
    • If you plan on attending more than one special event, you do not qualify for the Single Special Event License. Don’t fret! You have another option.
    • You can apply for the Multiple Special Event License, which remains in effect for a two-year period. Just remember, each event must have at least three vendors to be a qualifying event for this license.
  5. Exempt Certificate For Non-profit, Charitable, School, Religious or Government Organizations - If you are one of these organizations and have 501(c) (3) status from the Internal Revenue Service (IRS), the Colorado Department of Revenue can issue you an exemption certificate. However, you must have 501(c) (3) status before applying for the certificate.
  6. Exempt License For Contractors - This license is for contractors who are engaged in projects for tax-exempt organizations. They can qualify for this exemption certificate if they are planning on purchasing construction and building materials for these projects. It is important for contractors to remember that this license is issued only to the General Contractor. Sub-contractors must obtain a copy of the certificate from the General Contractor.
  • This is the most common type of sales tax license. To know if you qualify, you need to ask yourself two questions:
    • Are you a business with a permanent location?
      • ProTip: You only need one permanent location to meet the requirements for a standard sales tax license. You may have more than one business location, but only one needs to be considered permanent.
    • Are retail sales made at this location on a regular basis?
      • Protip: The applicable retail sales are those that establish a nexus with Colorado.
  • If you answered “Yes” to both questions, you qualify for a standard retail license because your business has at least one permanent location and engages in retail sales on a regular basis.
  • Some good news! You can qualify for this license if you also sell wholesale. In other words, if you sell both retail and wholesale, you only need this license. There is no need to get both the retail and wholesale license.
  • Do you make sales to retailers who will resell your products? If “Yes,” you qualify for a wholesale license.
  • Keep in mind, you do not need to apply for this license if your business also makes retail sales. You can use just a standard sales tax license for your business needs.
  • Are you unsure how to go about sales taxes because your business location is not permanent? If so, ask yourself these two questions:
    • Does your business make sales at a temporary location? Or, at an event that includes more than three vendors?
    • Do you only need a sales tax license for a one time event?
  • If you answered “Yes” to any of these questions, you can apply for a single special event license.

Home Businesses

Are you a small home businesses and wondering if you need a sales tax license?

We have some good news for you! You do not have to obtain the sales tax license for sales made from your home if you meet all of the following criteria:

  1. You make occasional or isolated sales of tangible personal property from your home
  2. Your total sales are no more than $1000 per year
  3. Neither you nor any member of your household is engaged in a trade or business selling similar items.

Even though you do not need to apply for a sales tax license, you still need to collect sales taxes.

This includes, if applicable, special district taxes, including Regional Transportation District (RTD), Cultural Facilities District (CD), and state-collected local tax on the gross sales price of each product you sell. Your total annual sales tax collection must be submitted to the Department of Revenue by April 15th of the following year.

Now that you know what sales tax license you need, it’s time to look at where you apply for it. This depends on the physical location of your business.

Is your business Inside Colorado?

  • Retail Sales or Retail and Wholesale Sales
  • Wholesale only
  • If you will be selling at one event that is not your normal business location
    • Get a single event license by completing form 0589 before the event.
  • You will be selling at more than one event that is not your normal business location
    • Get a multiple event license by completing form 0589 before the event(s).

Is your business located outside Colorado?


Using MyBizColorado is the fastest way

to set up your license.



What if I just need to update my information?

No need to worry!

If you are changing the mailing address, all you have to do is:

Whichever option you choose, the state will take care of the change for you.


Protip: You cannot change the address of the physical location address of your business in Revenue Online. Why? This is a safety measure. When you change the physical location of a business, there may be tax implications. For instance, it may change your tax jurisdiction. As such, the tax authorities in Colorado want you to contact them in writing via snail mail or email to ensure the proper jurisdictions are included for the business location or site.


Before we give you the contact information, we want to emphasize one more thing.

When you send a letter or email to the Colorado Department of Revenue, be sure to include the Colorado Account Number (CAN) and business contact information with the location address change.

Colorado Sales Tax FAQ


Colorado Sales Tax FAQ

By now, you have probably contacted the Colorado Department of Revenue and possibly even registered for a sales tax license. Now that you have finished the application process, you want to know when you are required to collect sales taxes. It is quite common for new business owners to have questions about this.

To know that, we should discuss the basics of taxable goods in the state of Colorado by looking at some frequently asked questions from our clients. I believe these will help me illustrate the nuances of when a business needs to charge sales taxes in Colorado, and when a business doesn’t need to.

Let’s start with the first question...



What products are considered taxable or not taxable in Colorado?



  • Goods - All tangible products
  • Services - Most services are untaxable. But, if services are included with tangible property on an invoice, then the services and tangible property must be itemized to show which line items will be taxable and which are exempt.


Not Taxable

  • Services - If the service does not include creating or manufacturing a product for sale, it is not taxable.
  • Only the following tangible items may qualify for exemptions:
    • Food, including food sold through vending machines
    • Machinery (Information available soon)
    • Farm Equipment
    • Sales of low-emitting vehicles
    • School related sales
    • Cigarettes
    • Renewable energy components
    • Space flight



The bottom line is …

If you are selling a product that does not qualify for an exemption, you need to charge a sales tax.




In addition to knowing what kinds of goods or services are taxable, you also need to keep in mind some other factors that trigger a sales tax in the state of Colorado.


So, Let's go over the following frequently asked questions:


  • Is Colorado an Origin or Destination Sales Tax State?
  • eCommerce, home rule, and destination nexus.
  • What creates Sales Tax Nexus in Colorado?
  • What is the economic threshold in Colorado?
  • Does Amazon have fulfillment centers in Colorado?
  • Does Colorado have Click-Through Nexus?


Why? Businesses are required to collect and remit sales taxes based on a variety of factors. While they must consider whether the good is taxable, they must also consider other criteria such as whether they established a taxing connection with the state. By going over these common questions that our clients have asked regarding Colorado sales tax, you will be able to better assess whether you have established such a connection with Colorado.


First things first.

Let’s talk about what kind of sales tax state Colorado is…


Is Colorado an origin or destination sales tax state?

Colorado is Destination Based Sales Tax State.

This means that you charge the local sales tax rates according to the buyer’s shipping address (where the product is received by the buyer).

For your reference, if a state has Origin Based Sales Tax, a business would collect and remit sales taxes based on the business’ location - much easier. However Colorado is not one of those origin based sales tax states.


Protip: Charge Colorado sales tax based on the location of the buyer.



To make managing your tax responsibilities easier, you can use an eCommerce or point of sale software to appropriately charge sales tax by customer location. If you do not collect sales tax when you were supposed to, you risk under or over collecting sales tax- both scenarios can result in fines and fees imposed on your business by the state.



eCommerce, home rule, and destination nexus

Destination nexus may seem like a simple concept until you realize that Colorado has many hundreds of sales tax jurisdictions and sellers are responsible for collecting and remitting sales tax for any jurisdiction in which they have made a sale.

The Colorado Department of Revenue’s online portal will allow businesses to remit to most sales tax jurisdictions but not all. Colorado has 61 cities and 35 towns that are “home rule” which means that they do not allow the state to collect sales taxes on their behalf. This means sellers are responsible for applying for sales tax permits in any of the 96 home rule areas in which they make a sale (usually with paper), collecting the correct amount of sales tax from their customers, and remitting directly to the home rule area (usually with a check in the mail).



More considerations about sales tax nexus

Now that we know that Colorado is a destination sales tax state, we need to also consider other criteria that could trigger a sales tax requirement at the point of sale.

Colorado recognizes several thresholds to trigger sales tax requirements.

We will use four commonly asked questions by our clients that can help explain these thresholds more efficiently:

  • What creates a sales tax nexus in Colorado?
  • Does Amazon have fulfillment centers in Colorado?
  • Does Colorado have Economic Nexus?
  • Does Colorado have a click-through Nexus?

Fear not! After we discuss these four questions in more detail, you will feel more confident in recognizing if your business meets any of the criteria triggering a tax connection with Colorado. You will also learn about the tools and resources available to manage your sales tax.



What creates sales tax nexus in Colorado?

Before answering this question, I want to stress one thing: if your business establishes nexus within Colorado, you are subject to sales tax even if your business is based out of state.

What is a sales tax nexus again?

Sales Tax Nexus is also known as "sufficient business presence.” If you have established this type of presence, you have created a taxing connection with the state. What does that mean? It means you are required to collect and remit sales tax in Colorado.

What if your main headquarters are in another state and you have no physical presence in Colorado? It is still possible to create sales tax nexus in Colorado even if you never step foot in Colorado. Businesses located in Colorado are not the only ones capable of creating a sales tax nexus with Colorado. Out of state businesses are capable of the same.

So, how do you create a Sales Tax Nexus in Colorado?



What creates sales tax nexus in Colorado?



There are three ways a business can create nexus in Colorado.

  • If a business has physical presence in Colorado such as an office, warehouse, or employee
  • If independent contractors/salespeople are soliciting business in the state
  • If an out of state business makes $100,000 a year in sales or completes 200 or more separate transactions in the state
  • If a business has products stored in an Amazon warehouse in the state


Does Amazon have fulfillment centers in Colorado?

Yes, Amazon has two fulfillment centers in Colorado.

For your convenience, here are the addresses of the Amazon fulfillment centers in Colorado:




19799 E 36th Dr

Aurora, CO 80011

Adams County


Sortation Facility



24006 E 19th Ave

Aurora, CO 80019

Adams County

Sept 17

Fulfillment Center


If you sell your products on Amazon or are recognized as an Amazon FBA (Fulfillment by Amazon), you want to know where Amazon has its fulfillment centers in any state including Colorado because this may trigger a sales tax requirement. If Amazon is storing your products in a warehouse in Colorado, you have created a taxing connection, or nexus, with the state of Colorado.


Protip: You create sales tax nexus by holding your goods in a warehouse (including one of Amazon’s) in the State of Colorado.


Considering Amazon has many fulfillment centers throughout the United States, you may feel overwhelmed with determining your tax obligations in Colorado as well as in other states.

We can help you with this process of identifying where your products are stored and what are the resulting tax implications.

We often use A2X + Wherestock to find out where our clients’ inventory is currently being held by Amazon across the country. This helps us determine what our clients need to do to be in compliance with all applicable state tax laws.


Does Colorado have economic nexus?

Yes, but only starting December 1st, 2018. As of December 1st, 2018, a retailer with no physical presence in Colorado must collect and remit Colorado state and local sales tax if it has:

  • $100,000 or more in gross sales in the state, including exempt sales; or
  • 200 transactions selling tangible personal property or services delivered into the state.

Meeting one of these two standards establishes an economic nexus in the state of Colorado.



Does Colorado have click-through nexus?

No, Colorado doesn’t have any extra requirements for affiliate marketers.



Is Colorado a streamlined sales tax state?


Some states have implemented this program in attempts to simplify sales tax law and make it easier for businesses to navigate regulations across multiple states lines... but Colorado is not one of them. At least not yet!



It’s time to wrap it up.

Knowing if your products are considered taxable goods and knowing if you reached any thresholds to establish a sales tax nexus with the state of Colorado is essential to effectively managing your business’ tax obligations.


Keep this guide handy to help you determine when to charge a buyer sales tax, so you and your business can be better-equipped to prevent negative tax implications such as 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 Colorado.


Having this information accessible will help you handle your tax needs more efficiently in less time.


Collecting Sales Tax in Colorado


Collecting Sales Tax In Colorado

Once you recognize your business has established a sales tax nexus with the state, you may have some questions about how to go about collecting sales taxes.

Many clients ask the following four questions:

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

After reading this, you will be better equipped to collect Colorado sales taxes.


How do I collect Colorado sales tax?

Because Colorado is a Destination-Based Sales Tax State, you collect Colorado sales taxes if the buyer’s address is within the state of Colorado.

What happens if you sell your products within a store you own? You collect the sales tax for your location directly via your POS system.

What happens if you sell your products online? If the buyer is located outside your district, you collect the tax for the buyer’s districts: state use tax (2.9%) + city + county + any local district taxes (such as Regional Transportation District (RTD), Scientific and Cultural Facilities District (CD) or Regional Transportation Authority (RTA) taxes).



What are the current Colorado sales tax rates?

Sales Tax Rates change all of the time- and vary by what is being sold! It's best to check out the Colorado Department of Revenue site here.



What items are exempt from Colorado sales tax?

The following goods and services are generally exempt from sales taxes in Colorado:

  • Food, including food sold through vending machines
  • Machinery
  • Farm Equipment
  • Sales of low-emitting vehicles
  • School related sales
  • Cigarettes
  • Renewable energy components
  • Space flight
  • Recreational Marijuana Sales are exempt from the 2.9% state tax only.

How you report your exemptions depends on the method of filing.

  • Revenue Online service:
    • You will be prompted to provide the exemption information and it will become part of the e-filed return.
  • Paper Return:
    • Itemizing them on the schedule included with the Retail Sales Tax Return.
    • You will then transfer or report them on the Retail Sales Tax Return.
    • If indicated on the "Other" line, you have to provide an explanation.
    • When you mail the return, you have to also submit the Exemptions schedule.



Protip: Exemptions may vary by state, county, city or special district.


Who is eligible for Colorado sales tax exemptions?

Now that you know what is exempt, you will also want to learn who is exempt from sales taxes. This depends on the buyer: (1) what kind of buyer they are, and (2) how they intend on using the goods. A common example is the wholesale buyer who buys goods with the intention of reselling them.

Other common examples of an exempt buyer may include:

  • Non-profit, school, religious or government organization.
  • General Contractors

Altogether, to determine who is exempt, you have to consider the type of buyer and the buyer’s intention for purchasing the goods.



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

When you do business with buyer who is exempt from paying sales taxes, you do not have to worry about filling out any paperwork because that is the buyer’s responsibility. However, you as the retailer must collect a Colorado Transaction Privilege Tax exemption certificate at the time you sell the buyer your products. Be sure to keep this on file so you can justify any tax-exempt sales in the case of an audit. If you lose the certificate or fail to obtain a copy, you risk having to pay the outstanding taxes yourself.

On the other hand, you will want to read the information I provide in the next question.


What happens if I lose a Colorado sales tax exemption certificate?

This is a really great question. For retailers, it is crucially important that you keep a copy of the certificate on file. Otherwise, you will be unable to verify that the buyer was exempt from paying sales tax in the event of an audit. In that case, the tax authorities will put the burden of paying the sales tax on you, the retailer.

However, you may want to know that the Department of Revenue provides a service where you can verify a business or organization’s tax exempt status through the “Additional Services” tab on Revenue Online. You would need to have the sales tax account number or exemption certificate number the buyer was provided with. You may want to make a note of this information as a backup in the instance you do lose a copy of the certificate.

There is no reason to worry if you are working with us. We will be sure to keep your sales tax exemption certificates safe and sound in our shared Box.com account.


Does Colorado have a sales tax holiday?

No, Colorado does not have a sales tax holiday. Boo. :(




Now you know more than you probably wanted to about Colorado Sales Tax! :) Hopefully you should feel prepared to collect the required sales taxes from who you need to and for what you need to. Once again, remember to document anytime you do business with a buyer who has a certificate of exemption. Being prepared and organized makes collecting and sales tax and filing a return in Colorado easy, as well as answering to any potential audits.

When is Colorado sales tax due?

Monthly returns are due the 20th day of the month following the reporting period.



What are the Colorado sales tax thresholds?

There are three thresholds you need to know about.

  1. Monthly Liability Threshold: More than $300 collected per month
  2. Quarterly Liability Threshold: More than $15 but less than $300 collected per month
  3. Annual Liability Threshold: $15 or less collected each month

Keep in mind that businesses that pay more than $75,000 annually in state sales tax must pay by Electronic Funds Transfer (EFT). Payment via EFT is due the 20th day of the month following the reporting period.

For wholesale businesses with a sales tax liability of $180 per year or less, you can file annually.


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. :)

Watch your mail for a letter from the State of Colorado so that you don't miss any deadlines.


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

You can file and pay your taxes on the next business day, typically the Monday following the weekend or the day after the holiday. But remember, filing early is always better than risk being late.


How do I file a Colorado sales tax return?


By Paper: Download and complete form DR-0100

Enclose payment and mail to:

Colorado Department of Revenue

Denver, CO 80261-0013


Electronic: File form by using Colorado Revenue Online; remit return and payment online



How do I correct a Colorado sales tax return?


  1. Login to your CO Revenue Online account.
  2. Select the tax period that needs to be amended.
  3. Select “Amend Return” from the options.



You must correct a return through paper applications in certain situations.

Situation 1: An overpayment of sales tax due a credit resulting from a mistake, error, or canceled sale, credit for the amount of overpayment may be taken on a subsequent sales tax form (DR 0100).

Situation 2: If you under report, a separate form for the same period must be filed. If you are filing an amended return, you are required to mark the Amended Return Box.

  • The amended return must show all tax columns as corrected, not merely the difference(s).
  • The amended return will replace the original return in its entirety.
  • Be sure to use the correct service fee rate for the period you are amending.

Situation 3: If you are no longer engaged in business and you have an overpayment or made a mistake on a prior return, you should apply for a refund using the Claim for Refund (DR 0137).


What happens if I don’t collect sales tax?

If sales tax was not collected but should have been, the business is still responsible for the tax due. To prevent having to pay yourself for taxes due by the customer, you should ensure that all sales tax collection information is set up in each Point of Sale system. Attempting to contact customers after the point of sale is often not possible.


Protip: You still owe The Colorado Department Of Revenue for sales taxes if you did not collect them from the buyer.


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

Late Filing/Failure to File Penalty: The greater of 10% of tax due plus 0.5% of tax due per month (maximum 18%), or $15.

Late Payment Penalty: The greater of 10% of tax due plus 0.5% of tax due per month (maximum 18%), or $15.



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

Yes, as it happens, a tax return must be filed even when the tax due is zero. If no return is filed, the department considers that to be a "nonfiler" situation, which is not good: When you don't file a return, you will receive nonfiler billing notices by mail and may even suffer automatic account/license closure.


**Watch this quick animated one-minute video for more information.**





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

Yes indeed!

When a business or a location (site) closes, you want to ensure the business closes in good standing with the Colorado Department of Revenue and does not receive nonfiler notices.

How can a business close in good standing?

  • Any taxes the business is expected to remit must be paid or returns with “zero” tax due must be filed.
  • The Department of Revenue must be notified on the final return that the business is closing. Include the effective date of closure (the last day of business). The department will then close the tax account for the entire business or for a specific location/site.
  • Businesses can close their account or site through Revenue Online and their closures will be effective the next business day. Businesses can also file the Account Change or Closure Form (DR 1102) to close the account or site, but this usually takes longer to process. Send the request to the address on the form.

Protip: If you decide to close your business or even just one of the multiple locations of your business, you must immediately notify the department no later than 30 days after closing your business. One reason to do this is to avoid receiving nonfiler notices.



Does The Colorado Department Of Revenue offer a discount for filing on time?

Yes, as it happens! For filing early, the state of Colorado offers a .0333 discount on the amount of tax due .

For example: If $100 of tax is due, a $3.33 discount will be given.




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

Some things to remember:

  • Due dates are important! If anything, we say file and pay your taxes early (such as before a holiday).
  • Determine what payment plan you must follow based on how much sales tax you collect.
  • You can file and pay your taxes, and even amend a return electronically or by mail.
  • Do not forget to collect sales taxes from your buyers or to obtain a copy of their exemption certificate. If you fail to do either of these, you (not the buyer) are liable to pay the sales tax to the state of Colorado.
  • Late fees will be applied for filing a tax return late and paying your taxes late.
  • Even if you collect no sales tax, you still need to file a return.
  • You need to file a “Final Sales Tax” when you close your business.

Let’s leave the good news for last (even though I know you will remember this).

  • There is a discount for filing your tax return on time.

Now, you are ready to file and pay your sales tax in Colorado. If you have any more questions, feel free to contact us.
