HB275 would eliminate New Mexico’s personal income tax by replacing the state’s graduated individual income tax rates with a flat rate of zero percent for taxable years beginning on or after January 1, 2026. The bill amends the Income Tax Act to remove the existing rate schedules for married joint filers, single filers, estates and trusts, and married separate filers, effectively making individual income tax liability zero for those categories going forward.
The bill also changes filing rules. Under current law, many residents and individuals with New Mexico-source income are required to file returns; HB275 would make filing optional by stating that eligible taxpayers “may” file a complete return rather than must file one, while preserving the department’s authority to prescribe return form and content. The bill applies prospectively to taxable years beginning on or after January 1, 2026, and takes effect the same date.
Impact
HB275 would substantially alter state tax law by repealing the operative individual income tax rates in Section 7-2-7 and revising Section 7-2-12 to remove the mandatory filing requirement for residents and certain nonresidents with New Mexico income. In practical terms, it would eliminate personal income tax collections from individuals, estates, and trusts beginning in 2026, which would likely have major implications for state general fund revenue and for taxpayers who currently file annual returns. The bill does not appear to change business taxes, gross receipts taxes, or other state tax categories.
Sentiment
The available context shows no committee transcript or recorded votes, so there is no documented floor or committee debate to gauge formal legislative sentiment. Based on the bill’s caption and text, the measure is strongly tax-cut oriented and would likely be supported by taxpayers seeking lower tax burdens and opposed by those concerned about state revenue stability and funding for public services. The introduction by multiple sponsors suggests at least some organized support among legislators.
Contention
The main point of contention is the fiscal impact of eliminating the personal income tax, since that tax is a major source of state revenue and its removal would require either significant spending reductions or replacement revenue. Supporters would likely emphasize tax relief, simplicity, and reduced filing burdens, while opponents would likely focus on the effect on education, healthcare, infrastructure, and other state-funded programs. Another possible issue is the administrative change from mandatory to optional filing, which could affect compliance, withholding reconciliation, and the state’s ability to track income information.
