What is a Sales Tax Permit in New Mexico?

A sales tax permit in New Mexico is an authorization issued by the New Mexico Taxation and Revenue Department that allows businesses to collect gross receipts tax (GRT) from customers. Unlike many states that use a traditional sales tax, New Mexico applies GRT to the seller rather than the buyer, but the effect is similar; businesses must collect tax and remit it to the state.

This permit confirms your business is registered for sales tax registration in New Mexico and is compliant with the state’s tax laws. It’s required for most businesses making taxable sales or providing taxable services in New Mexico, including both local and remote sellers.

Both physical and remote seller sales tax registration in New Mexico are required under state law to ensure proper tax collection and sales tax remittance.

Do You Need to Register for a Sales Tax Permit in New Mexico?

If you are doing business in New Mexico, you are required to register for a sales tax permit if you meet certain criteria. Having a physical presence, such as an office, store, warehouse, or employees within the state, automatically requires you to obtain a permit. However, even if you don’t have a physical location in New Mexico, you may still need to register if your sales meet the state’s economic nexus thresholds.

Currently, this means making over $100,000 in sales annually within New Mexico. Remote sellers who exceed these thresholds must also register. Additionally, if you operate as a marketplace facilitator, you are responsible for registering and collecting taxes on those transactions.

Lastly, any business engaging in taxable retail sales or providing taxable services in New Mexico must secure a sales tax permit to comply with state regulations.

Step-by-Step: How to Get a Sales Tax Permit in New Mexico?

Registering for a New Mexico sales tax permit is a straightforward process if you have all the necessary information ready. Below is a step-by-step guide to help you complete your registration smoothly:

Step 1: Gather Required Business Information:

Before starting your application, ensure you have the following details:

  • Federal Employer Identification Number (EIN): This is a unique nine-digit number issued by the IRS to identify your business for tax purposes.
  • NAICS Code: The North American Industry Classification System (NAICS) code is used to identify your business’s primary activity.
  • Business Address: Both your physical location (if applicable) and mailing address where business-related documents will be sent.
  • Responsible Party Information: The individual responsible for the business’s tax filings, including their name, contact details, and Social Security Number or ITIN.

Step 2: Access the New Mexico Taxation and Revenue Department Website:

Visit the New Mexico Taxation and Revenue Department’s Business Registration Portal to begin the registration process. This is where you’ll submit your application and access all necessary forms.

Step 3: Complete the Gross Receipts Tax (GRT) Application:

The portal will guide you through a series of questions about your business. You’ll need to provide information like the type of business, locations of operation, and the nature of goods or services sold. Make sure to enter all details correctly to avoid delays in processing.

Step 4: Submit the Application:

After completing the application, carefully review all the information for accuracy. Once confirmed, submit your application electronically via the portal. You will receive immediate confirmation that your application has been submitted.

Step 5: Pay Any Applicable Fees:

In New Mexico, obtaining a sales tax permit (GRT number) is free. Unlike some other states, New Mexico does not charge an application fee for registering your business for gross receipts tax.

Step 6: Receive Your Permit Confirmation:

Once your application is approved, you will be issued a GRT number, which allows you to legally collect and remit sales tax. The confirmation and your GRT number will be sent to you via email, and you can access your account through the New Mexico Taxation and Revenue Department’s portal to manage future filings and payments.

What Information Do You Need to Register?

Before you start the sales tax registration in New Mexico, gathering all necessary information ahead of time will make the application process much smoother and faster. Having these details ready ensures you avoid delays or errors that could cause your registration to be rejected or require corrections later. Here’s what you need:

Business Information

  • Legal Business Name and DBA (Doing Business As) Name
     This is the official name under which your business operates. The legal name is the one registered with your state or county government. If your business uses a different trade name or brand (commonly called a DBA), you’ll need to provide that as well. For example, “Sunshine Enterprises LLC” might operate a store called “Sunshine Apparel,” which would be your DBA.
  • Physical and Mailing Addresses
     The state requires your business’s physical address, where your business is actually located or where it conducts its operations. If you have a separate mailing address (such as a P.O. Box or a different office location where you receive mail), you will need to provide that as well. Accurate addresses are crucial because official correspondence, tax forms, and permits will be sent there.
  • Business Start Date and Location Details
    The exact date when your business began or will begin operations in New Mexico is necessary for the state to track your tax obligations and filing deadlines. Additionally, specify any locations where your business operates, as this can affect your gross receipts tax rates and Sales tax nexus status. 

Employer Identification Number (EIN)

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business for tax purposes. It functions similarly to a Social Security Number but is specifically for businesses. The New Mexico Taxation and Revenue Department requires your EIN to verify your business’s identity and link your state tax account to your federal tax records. If you do not have an EIN, you can apply for one through the IRS website.

NAICS Code

The North American Industry Classification System (NAICS) code is a six-digit number used to classify your business’s primary industry or economic activity. The NAICS code helps the state categorize your business and determine applicable tax rules and rates. It also assists in statistical data collection and economic reporting. You can look up your NAICS code based on your business activities on the official NAICS website.

Responsible Party Details

The responsible party is the individual who controls, manages, or directs the business. This person is accountable for tax compliance and correspondence with the state. You will need to provide the responsible party’s full name, Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and contact information such as phone number and email address.

How Much Does It Cost to Register for a Sales Tax Permit in New Mexico?

Registering for a state of New Mexico sales tax permit is free. There are no fees associated with applying for or obtaining your gross receipts tax identification number.

Unlike some states that charge application or renewal fees, New Mexico does not require annual permit renewal fees, but you must stay current on your filings to remain compliant.

How Long Does It Take to Get Approved?

In New Mexico, the approval process for a sales tax permit is generally fast and efficient. Most applicants receive their permit immediately or within a few business days after submitting the application online. Because the entire process is electronic, you will usually get your permit number and login details via email shortly after approval.

This quick turnaround allows businesses to start collecting and remitting gross receipts tax without delay. However, if you don’t find a confirmation email in your inbox within a few days, it’s a good idea to check your spam or junk mail folders, as automated emails sometimes get filtered there. If you still don’t receive confirmation, contacting the New Mexico Taxation and Revenue Department directly will help resolve the issue.

Common Mistakes to Avoid When Registering

  • Selecting the wrong business type or NAICS code: Choosing an incorrect business type or NAICS code can lead to mismatched tax requirements or penalties. Make sure your business activities align with the appropriate classification to avoid complications.
  • Skipping registration for marketplace facilitator obligations: If you sell through an online marketplace, you may be required to register as a marketplace facilitator. Failing to do so can result in non-compliance with tax laws for transactions processed on your behalf.
  • Providing incorrect contact information: An incorrect address or contact info can delay important correspondence (permit approvals or tax notices). Double-check your details to ensure all communication reaches you promptly.
  • Forgetting to do New Mexico remote seller sales tax registration​: If you exceed New Mexico’s economic nexus thresholds, you must register as a remote seller. Ignoring this requirement can result in penalties for uncollected sales tax.
  • Missing deadlines or filing requirements: After receiving your sales tax permit, it’s crucial to file on time and follow reporting requirements. Missing deadlines can lead to fines or the suspension of your permit.

What Happens After You Register?

Once you’ve registered for a New Mexico sales tax permit, you must:

  • Start adding the appropriate gross receipts tax (GRT) to all taxable goods and services you sell in New Mexico, according to the state’s rate structure.
  • Depending on your business’s sales volume, you’ll need to file returns monthly, quarterly, or annually, and send in the taxes you’ve collected from your customers.
  • Even if your business has no taxable sales during a period, you must submit a “zero” return to ensure your account remains in good standing with the state.
  • Keep accurate records of your sales, tax collected, and any other relevant business activities in case of a tax audit or review by the state.

Special Considerations for Out-of-State or Remote Sellers

If you are an ecommerce or remote seller, New Mexico’s economic nexus rules mean you must register if your sales exceed $100,000 in a calendar year.

Marketplace facilitators are also required to collect and remit GRT on behalf of sellers using their platform.

For remote seller sales tax registration in New Mexico, be aware of the state’s reporting and filing obligations, which may differ slightly from in-state sellers.
