N.M. Code R. § 3.1.4.15
For purposes of reporting taxes due on a monthly basis, the reporting period is a calendar month unless the taxpayer has obtained the secretary's permission to use another period, such as reporting based on standardized calendar quarters of 4 weeks, 4 weeks and 5 weeks or thirteen months of 4 weeks. Because of complications introduced by deviations from the calendar month reporting, the secretary may require substantial justification before approving any significant departure from the calendar month reporting cycle.
