The filing of a "tentative" return is not allowed by taxpayers filing New Mexico income tax returns within the meaning of Section 7-2-12 NMSA 1978. Taxpayers wishing to make a prepayment of their tentative or estimated tax liability prior to the due date of the return should use a prepayment form PIT-P. The instructions on the form PIT-P should be followed carefully to ensure that any prepayment is applied to the correct taxable year. This regulation is applicable to taxable years beginning on or after January 1, 1995.
