What are the penalties for not paying New Mexico gross receipts tax?
If you fail to file or pay New Mexico gross receipts tax on time, you may face a penalty of 2% per month (or partial month), up to a maximum of 20% of the tax owed. A minimum penalty of $5 applies even if no tax is due.
Interest also accrues daily on any unpaid tax at a rate set quarterly by the New Mexico Taxation and Revenue Department. Because the rate changes each quarter, check the TRD's current penalty and interest rate page for the most up-to-date figure.

New Mexico sales tax audits & appeals
If a business is selected for a gross receipts tax audit by the New Mexico Taxation & Revenue Department, a defined process will follow. Understanding what to expect can help businesses properly prepare.
New Mexico gross receipts tax audit selection
There are a few reasons the Taxation & Revenue Department may select a business for audit, including:
- Random selection
- Referral from a third party like a vendor or customer
- Your business activities seem inconsistent with reported tax amounts
- Previous audit identified issues or trends requiring follow-up
Generally, larger companies with more complex operations are audited more frequently than small businesses. However, companies of any size can be selected at the TRD's discretion.
New Mexico gross receipts tax audit process step-by-step
- Audit Notice Issued: The New Mexico Taxation & Revenue Department will first issue a formal notice by mail that you have been selected for an audit. This notice will provide information on the audit scope, timing, and records needed.
- Information Request: Early in the process, the auditor will submit detailed lists of the financial statements, tax records, exemption certificates, and other documentation required. You will have 30 days to gather and submit this.
- Audit Conducted: The in-person or virtual audit will involve the TRD auditor thoroughly reviewing your submitted records, asking clarifying questions, and determining compliance. This may take a few weeks.
- Audit Findings Issued: Once the audit concludes, the TRD will provide preliminary written findings outlining any deficiencies found and details on taxes, penalties, and interest owed if discrepancies were identified.
- Protest Audit Findings: If you disagree with the audit results, you have 30 days from receiving the proposed assessment to provide a written protest explaining what you contest, along with all supporting documentation. This begins the appeals process.
Appealing the results of an audit
If you submit a protest but the Taxation & Revenue Department upholds the audit findings, you can pursue further administrative appeals with the New Mexico Tax Administration Hearings Office. This will initiate a hearing with a tax tribunal.
The appeals process can be complex, so working with a sales tax professional can be beneficial throughout an audit and appeal. Keeping detailed financial records is also key to supporting your compliance efforts.
