Top Recordkeeping Mistakes That Lead to WDT Violations

Accurate recordkeeping is key to complying with New Mexico’s Weight Distance Tax (WDT). Common mistakes can lead to penalties, audits, or suspension. Knowing these errors helps protect your business.


Incomplete Mileage Records

One of the most frequent issues is failing to maintain complete and accurate mileage logs. Every mile traveled within New Mexico must be properly documented. Missing trip details, inconsistent entries, or reliance on estimates rather than actual data can quickly raise red flags during an audit.

Truckers should ensure their records include the following:

  • Trip dates
  • Origin and destination
  • Routes taken
  • Total miles driven within New Mexico

Misclassifying Vehicle Weight

Tie WDT rates directly to your declared gross vehicle weight. If you misreport or fail to update your weight class, you can underpay or overpay taxes. These scenarios create compliance issues, especially when reviewers discover discrepancies.


Poor Documentation Retention

Many carriers fail to retain records for the required period. New Mexico requires you to retain supporting documents such as fuel receipts, trip logs, and dispatch records for several years. Without these, you cannot defend your filings if questioned.


Manual Errors in Calculations

When you rely on manual calculations, you increase the risk of math errors, incorrect totals, or missed entries. Even small mistakes compound across multiple filings, creating significant discrepancies and potential penalties.


Ignoring Filing Deadlines

Disorganized recordkeeping often causes late or missed filings. Without a structured system, you can easily overlook deadlines, resulting in fines and added stress.
