Is SaaS taxable in New Mexico?
The rule
New Mexico treats SaaS as a license to use software, with gross receipts tax imposed on the seller for the full charge.
The main exception
New Mexico's gross receipts tax also covers services, so custom programming, setup and training are taxable too.
What to do
Get a nontaxable transaction certificate from any reseller before you deduct their purchases, because without one the receipts stay taxable.
Is your product taxable in New Mexico?
Whether a particular product is taxed in New Mexico can depend on two things: how the software reaches the customer and how you write the invoice.
Does it matter how the software reaches the customer?
In New Mexico, downloaded software is taxable. Software counts as downloaded when the customer installs a copy, such as a desktop app, an agent or an offline client, even if most of the product runs online.
Does it matter how you write the invoice?
In New Mexico, setup, implementation and training fees are taxable. Listing them on their own invoice lines, rather than inside one software price, is what lets them be treated separately.
How are other software products and services taxed in New Mexico?
SaaS rarely ships alone. This is how New Mexico treats the products and charges that usually sit next to it on an invoice.
| Product or charge | Treatment |
|---|---|
| Downloaded software | Taxable |
| Custom software | Taxable |
| Cloud infrastructure and platforms (IaaS, PaaS) | Taxable |
| AI tools and API access | Taxable |
| Digital goods (e-books, music, video) | Taxable |
| Maintenance and support | Taxable |
| Setup, implementation and training | Taxable |
Does New Mexico tax B2B and B2C SaaS differently?
No. New Mexico treats SaaS the same way for business and consumer buyers.
How much sales tax do you charge on SaaS in New Mexico?
SaaS is taxed at a base rate of 4.875%, and the typical combined rate is 4.875% to 8.9375%.
Do cities or counties tax SaaS differently?
No. Cities and counties follow the state's rules for SaaS, so whether it is taxed does not change from one address to another.

Do you need to register for sales tax in New Mexico?
Physical and economic nexus
Registration follows nexus. Once you have nexus in New Mexico and sell something taxable there, you need to register. Nexus comes from a physical presence, such as an office, staff or inventory in the state, or from passing an economic threshold.
In New Mexico, the economic nexus threshold is $100,000 in taxable sales over the previous calendar year. Only taxable sales count toward it. Our New Mexico nexus guide covers the rules in full.
Which address sets the rate
For remote sellers, the rate is based on where your customer is, not where your business or servers are. New Mexico has no multiple points of use certificate, so the full charge is taxed at the customer's location.
Buyers who do not pay tax
Some buyers can give you a certificate instead of paying tax. In New Mexico, that includes resellers and other buyers with a nontaxable transaction certificate, government agencies and certain nonprofits. Collect the certificate at the time of sale and keep it, because in an audit it is the only thing standing between you and the tax.
How to register, collect and file in New Mexico
Register
If you need to register, do it with the New Mexico Taxation and Revenue Department through the Department's Taxpayer Access Point (TAP). Note your account number and the filing frequency you are given, since both decide when and how you file.
Collect the right amount
Charge tax only on what New Mexico taxes. Collecting tax that is not owed creates its own refund and audit problems.
- List services on their own invoice lines, so each charge is taxed on its own terms.
- Describe each product on the invoice the way it actually reaches the customer: online access, a download or something shipped.
- Recheck the treatment whenever you add a desktop app, a hardware option or a new add-on, since each can change what is taxable.
File and keep records
Your filing frequency is assigned when you register: monthly, quarterly or semiannually, depending on how much tax you owe. Returns are due by the 25th of the month after each period ends.
You must file a return for every period, even when no tax is due.
Keep invoices, exemption certificates and returns for at least three years. That paperwork is what decides the taxable amount if you are audited years later.
What should SaaS businesses watch when selling in New Mexico?
Past sales where no tax was charged
If you should have been collecting and were not, the New Mexico Taxation and Revenue Department can assess the unpaid tax plus a penalty of 2% a month up to 20% and daily interest.
A voluntary disclosure agreement can reduce penalties if you come forward first. Work out which past sales were taxable before you come forward, so you know the size of the exposure.
