Brackets are legislated and change on a fixed calendar, so the year matters.
  • New Mexico taxes retirement money more heavily than its reputation as a retiree state suggests: private and public pensions and all qualified plan distributions are ordinary income, and the only categorical breaks are the Social Security threshold exemption and the military retirement exemption.
  • The Social Security cliff at $100,000/$150,000/$75,000 makes the marginal cost of one extra dollar of income near the line enormous. A retiree planning a Roth conversion or a large IRA withdrawal in New Mexico should model the year against those thresholds before the year ends, because crossing them re-taxes the entire benefit rather than the extra dollar.
  • DELIBERATE OMISSION, stated rather than left blank: autoIraProgram is not populated. New Mexico's Work and Save Act created a state-facilitated retirement savings marketplace and a voluntary payroll-deduction IRA, but it does not impose an employer mandate of the kind New York, Oregon, Rhode Island and Illinois have. Recording it in a field whose other entries are live mandates would misrepresent an employer's obligations here.
