New Mexico Gross Receipts Tax Audit Readiness
Checklist
A New Mexico gross receipts tax (GRT) audit begins when the New Mexico Taxation and
Revenue Department (TRD) believes the tax you reported may not match what you owed for a defined period. The review focuses on receipts, records, and filing history. A gross receipts tax audit readiness checklist helps you respond to an audit notice on time, reduce the risk of estimated assessments, and confirm your tax liability using documentation that supports your tax returns.
What This Issue Means
A gross receipts tax (GRT) audit is a formal request from the New Mexico Taxation and
Revenue Department (TRD) to review your business records and confirm that you reported and paid the correct gross receipts tax for the audit period. The examiner reviews sales documentation, NTTCs (Nontaxable Transaction Certificates), and other documentation supporting deductions, purchase records, and tax returns, and the process verifies compliance rather than assigning fault at the start.
Why the State Issued This or Requires This
New Mexico uses gross receipts tax audits as a routine compliance tool, and selection often follows unusual filing patterns, large year-over-year changes in reported receipts, industry-focused review activity, complaints, processing discrepancies, or random selection. The state does not publish all audit selection factors, and the state’s goal is to verify that taxable receipts were reported and that deductions, including NTTC-based deductions, were supported by records consistent with state and local tax rules and local jurisdictions.
What Happens If This Is Ignored
Non-response to an audit notice can lead New Mexico to issue an estimated assessment without your records, and the assessment can include additional tax, penalties, and interest based on estimates rather than your actual documentation. Collection activity can follow continued non-response, and actions may include liens or wage garnishment in some cases, which increases cost and complexity as the audit remains unresolved.
What This Does Not Mean
A gross receipts tax audit notice does not mean the state has already decided you owe additional gross receipts tax, and it does not automatically place penalties on your account at the start of the examination. The notice does not indicate criminal charges or business license revocation, and the state uses an audit as an administrative review that becomes final only after the state issues an audit report or assessment.
Audit Response Steps
Step 1: Verify the Notice Is Legitimate
Check the notice for the official New Mexico Taxation and Revenue Department (TRD)
letterhead and contact information. Confirm the sender's phone number by calling the main switchboard at the Taxation and Revenue Department (not a number provided in the notice itself). Verify that your business name, identification number, and the tax period being audited match your records. Do not respond to notices that cannot be verified through official state channels.
Step 2: Identify the Audit Period and What Is Requested
Note the specific tax period (months or quarters) covered by the audit. List all documents the notice asks you to provide (sales records, NTTCs, and/or other documentation supporting deductions, purchase invoices, bank statements, etc.). Identify the deadline for submitting documents—this date is critical. Make a copy of the audit notice for your records before proceeding.
Step 3: Gather Required Documentation
Locate all sales records (point-of-sale records, sales journals, invoices) for the audit period.
Collect NTTCs and documentation supporting any claimed deductions from gross receipts tax.
Gather purchase records and supplier invoices showing items acquired for resale or business use. Compile bank statements and accounting records that correspond to reported sales figures. Retrieve any prior correspondence with the state regarding gross receipts tax for this period. Do not alter, backdate, or create new documents—provide what exists from that time period.
Step 4: Organize Documentation in a Clear Format
Sort documents chronologically or by category (sales, deductions/NTTCs, purchases) based on what the notice requests. Create a cover sheet listing all submitted documents with brief descriptions. Number or label each document clearly to match your cover sheet. Avoid binding documents permanently—use paper clips or folders that allow review. Keep a complete copy of everything you submit for your own records.
Step 5: Respond to the Audit Notice by the Deadline
Confirm the deadline stated in the audit notice and mark it on your calendar. Prepare a brief cover letter explaining what documents are enclosed and your contact information. Submit documents to the address specified in the notice (do not assume a mailing address—verify it from the notice). Use certified mail or a delivery method that provides proof of receipt if the deadline is approaching. Do not email documents unless the notice specifically authorizes electronic submission and provides an email address.
Step 6: Keep Records of Your Submission
Save copies of your cover letter and cover sheet. Retain proof of mailing or delivery (tracking number, certified mail receipt, or email confirmation). Document the date and method of submission. Keep notes on any phone conversations with the audit examiner, including the date, time, and topics discussed.
Step 7: Respond to Follow-Up Requests Promptly
If the examiner requests additional documents or clarification, respond within the stated timeframe. Do not assume silence means the audit is complete—audits can take several months. If you do not understand a request, contact the examiner to clarify what is needed. If you cannot locate a document, provide a written explanation of why it is unavailable.
Step 8: Review the Audit Findings When Received
Carefully read any audit report or assessment that the state issues. Check that the tax period, reported amounts, and calculations are accurate based on your records. Identify any items you disagree with or believe are incorrect. Note the deadline for filing a protest or appeal if the assessment shows additional tax owed.
Step 9: Address Disagreements or Errors
If you believe the audit findings are incorrect, review the state's protest procedures. File a protest within the deadline specified in the audit report. Provide clear documentation supporting your position and explaining why the findings are inaccurate. If you cannot resolve the issue, contact a tax professional or the New Mexico Taxpayer Advocate Office for guidance.

Step 10: Arrange Payment or Next Steps

Contact the Taxation and Revenue Department to discuss payment plans if you cannot pay the full amount immediately. Keep all payment records and correspondence for your files.
What Happens After This Is Completed
After you submit the requested documentation, the audit examiner reviews your records and prepares findings, and the timeline often ranges from several weeks to several months, depending on complexity and completeness. The state issues a formal audit report or assessment letter that explains results, outlines any additional tax, penalties, or interest, and confirms whether the matter closes with no change.

Frequently Asked Questions
How long does a gross receipts tax audit typically take?

Can I request an extension on the deadline to submit documents?
The audit notice provides instructions for contacting the examiner, and you should contact the examiner before the deadline if you need additional time to locate or organize records.
Extensions are typically granted for legitimate reasons, and timely contact helps you document that you requested additional time.
What if I no longer have certain records?

The examiner may proceed with the remaining documentation or request alternative records that support the same sales or deduction entries.
Can I appeal the audit findings?

period for many tax assessments and notices, and you should track the deadline listed in your notice.
What if I disagree with the audit findings?
You should file a formal protest within the deadline stated in the audit report, and you should include documentation that supports your position and explains why the findings are inaccurate.
A clear record set that ties your receipts, deductions, and tax returns to the audit period supports effective review during the appeal process.
