What Are Exemption and Resale Certificates?

Exemption and resale certificates let eligible buyers avoid paying gross receipts tax on qualifying purchases. Correct use is critical for compliance under New Mexico’s unique gross receipts tax system

The following are the two certificates:

• A resale certificate is used by businesses that purchase items to resell them to end consumers.
• An exemption certificate is used by qualified entities (like nonprofits or government agencies) that are legally exempt from paying gross receipts tax on certain purchases.

To obtain either certificate, apply for a Non-Taxable Transaction Certificate (NTTC) via the New Mexico Taxation & Revenue Department’s TAP portal. The default form is NTTC-1 (General Certificate), while other forms are used for special exemptions.

The following table provides an overview of the differences between the certificates:

Accurate exemption certificates are critical for tax audits in New Mexico. The Taxation & Revenue Department requires businesses to maintain complete, up-to-date exemption documentation; missing or invalid certificates can result in back taxes, penalties, and interest for the seller.

Note: For those unfamiliar, what is a New Mexico sales tax exemption certificate? It’s a state-recognized document that allows qualified buyers to make tax-free purchases on eligible goods or services under New Mexico’s gross receipts tax system.

Required Information on the Certificate

To be valid, a buyer-specific sales tax exemption certificate in New Mexico must include:

• Buyer’s name, address, and New Mexico tax ID (if applicable)
• Seller’s name and address
• Exemption reason and type code (e.g., Type 2 for resale, Type 9 for nonprofit/government)
• Description of the items or services
• Authorized signature
• Date of execution
• Expiration date or validity statement
• Declaration accepting tax liability for misuse

Validity Period and Renewals

The validity of a sales tax exemption certificate in New Mexico depends on the exemption type and specific circumstances:

• Most standard New Mexico sales tax exemption certificates (resale, manufacturing) are valid for 4 years from issue.
• Government and nonprofit certificates (Type 9): four-year term, renewal needed.
• Certain certificates may remain valid until revoked, but sellers should always verify current details.
• Educational exemptions may carry 5-year terms with separate renewal steps.
• Manufacturing exemptions (Type 11, Type 12) also use the four-year validity period.

Paper vs. Electronic Submission

New Mexico accepts both paper and electronic versions of the sales tax exemptions. The TAP portal is encouraged for its ease and instant validation:

• Apply, execute, and manage certificates online using TAP, with real-time status checks.
• Still accepted, but must be fully completed and meet state formatting rules.
• Keep digital or paper records for at least 4 years for audit purposes.
• Both formats are valid if all required fields are present and legible.

Common Pitfalls and Compliance Risks

Handling every New Mexico sales tax exemption certificate requires careful attention. Small mistakes in documentation or record-keeping can quickly lead to audit issues or unexpected tax bills.

• Expired certificates: If you’re asking, do sales tax exemption certificates expire in New Mexico? Most are valid for 4 years. Letting certificates lapse can expose sellers to tax assessments and penalties if audited.
• Incomplete information: Missing key details (buyer/seller info, exemption code, item description) invalidates certificates and exposes sellers to tax liability.
• Ineligible buyers: Accepting certificates from buyers who are not qualified or using the wrong exemption type triggers reassessments and back tax exposure.
• Lack of renewal: Not updating certificates as they expire increases audit risk.
• Poor record retention: Certificates must be kept for at least 4 years; insufficient records make it difficult to justify exemptions if reviewed.

Compliance Failure Example:

A New Mexico retailer who overlooks certificate expirations and accepts outdated documents risks major audit issues. If expired certificates are found during an audit, the state will assess back taxes at current New Mexico sales tax rates and impose penalties, expenses easily avoided by actively tracking certificate validity.

Best Practices for Managing Exemption Certificates

Managing a New Mexico sales tax exemption certificate correctly protects your business from costly errors and audit exposure. Consistent organization and up-to-date records are essential to keeping your operations compliant with state requirements.

• Collect certificates at the time of transaction: If you’re asking, How do I get a New Mexico sales tax exemption certificate?, simply register for your New Mexico Business Tax ID and apply through the TAP portal provided by the New Mexico Taxation & Revenue Department.
• Validate All Details: Check every certificate for correct buyer/seller info, exemption type, signatures, and expiration date. Only approve for eligible buyers.
• Digital Storage: Keep certificates securely stored electronically for quick retrieval and audit readiness.
• Renewal Reminders: Track expiration dates and notify buyers well before certificates expire to keep them current.
• Internal Audits: Regularly review your certificate files to remove outdated, incomplete, or incorrect records and stay compliant.
