How New Mexico treats gambling losses
New Mexico allows the deduction only to filers who itemize on the federal return. Take the federal standard deduction and the offset disappears, so gross winnings are taxed even in a year you finished down.
The two examples below are the same numbers the calculator uses, worked at New Mexico rates.
Two examples, worked at 2026 New Mexico rates
A single filer with $60,000 of other income who takes the standard deduction on everything except gambling losses.
A losing year
You win $50,000 and lose $52,000, so you finish down $2,000.
- Federal
- $3,596
- New Mexico
- $907
- Total
- $4,503
You finished the year down and still owe tax.
Federally you itemize, so your losses offset your winnings, but the 2026 rule caps that deduction at 90 percent and leaves $3,200 taxable. New Mexico allows the loss deduction only to filers who itemize federally, which you do. Your New Mexico income, after the federal standard deduction, or your itemized deductions where you itemize federally and they are larger, goes from $43,900 without the win to $63,200 with it. The extra $19,300 is taxed at 4.7 percent, which comes to $907.
A winning year
You win $50,000 and lose $10,000, so you finish up $40,000.
- Federal
- $10,350
- New Mexico
- $2,405
- Total
- $12,755
Federally you take the $16,100 standard deduction, which is worth more than itemizing, so your gambling losses do not reduce your federal tax at all. New Mexico allows the loss deduction only to filers who itemize federally, and you do not. Your New Mexico income, after the federal standard deduction, or your itemized deductions where you itemize federally and they are larger, goes from $43,900 without the win to $93,900 with it. The extra $50,000 is taxed at graduated rates, which comes to $2,405.
