No tax change from the ballot. Rates are unchanged; a $10,000 physician credit begins in 2027. This page keeps apart three things that get mixed together in the news: what is on the 2026 return you file in early 2027, what begins with tax year 2027, and what is scheduled, conditional or still undecided after that. Election figures are the unofficial November 3, 2026 returns and are not final until the state certifies them.
What the voters decided on November 3, 2026
No statewide tax measure was on the November 3, 2026 ballot in New Mexico. Nothing voted on that day changes a New Mexico return.
This return, next year, and later
| When | What applies |
|---|---|
| The 2026 return, filed in early 2027 | Rates and brackets are unchanged. |
| The federal car-loan interest deduction flows through; the $6,000 senior deduction does not. | |
| Starting with tax year 2027 | A $10,000 credit for physicians who provide at least 1,584 hours of care in New Mexico begins, for 2027 through 2031. |
| Corporations add back federal bonus depreciation beginning in 2027. | |
| 2028 and later, or conditional | No rate change is enacted. |
Items under 2027 and later do not change the 2026 return. They matter for 2027 withholding, estimated payments and planning. The detail behind each line is in the other New Mexico articles.
The 2025 federal law and the New Mexico return
New Mexico starts from federal adjusted gross income and then borrows the federal standard or itemized deduction. It does not follow the higher federal cap on state and local taxes.
That is the reason a change on the federal return, such as the deductions for tips, overtime and people 65 and older, may or may not show up on the New Mexico return. The federal side is in The new deductions for tips, overtime and seniors.
What to watch
The 60-day session that opens in January 2027. When something on this page changes, the change is logged on the updates page with its date.
What to bring
- Your 2026 federal and New Mexico returns, once filed, to set 2027 withholding and estimated payments against them
- Your last pay stub of 2026 and the first of 2027, to see whether withholding changed
- Any notice from the state about a 2027 rate, credit or filing change
Questions people ask
Does anything here change the New Mexico return I file in early 2027?
Only what is listed under the 2026 return. Everything listed under 2027 or later affects withholding, estimated payments and planning, not the return for 2026.
How will I know if this page changes?
Every change is logged on the updates page with its date and the article it affects. State legislatures meet in early 2027 and some act before the filing deadline.
New Mexico, after the election
No tax change from the ballot. Rates are unchanged; a $10,000 physician credit begins in 2027.
