The rule in New Mexico
The rule is set out in NM DWS Labor Relations Division Investigations Manual (July 30, 2025).
Use-it-or-lose-it. We found no New Mexico statute or agency rule on use-it-or-lose-it policies, so the employer’s written policy usually decides.
What to check in your policy
Your handbook or offer letter decides. If it promises payout, that promise can usually be enforced. If it says unused time is forfeited, or says nothing, you may not be owed it. Keep a copy of the policy that was in force when you earned the time.
Tax on a New Mexico payout
A payout is taxable wages. Take 80 unused hours at $25.00 an hour, worth $2,000.00. Paid on top of regular wages, it is a supplemental payment, so many employers withhold $440.00 of federal income tax at the flat 22% rate, plus $124.00 of Social Security and $29.00 of Medicare, leaving about $1,407.00.
New Mexico income tax is withheld on top of that, under the state’s own rules, so you will receive somewhat less. Withholding is not the final tax; any difference is settled on your return.
Questions people ask
Does New Mexico require employers to pay out unused PTO?
Not by law. New Mexico has no statute requiring employers to provide or pay out vacation. If vacation is earned under your employer's written policy, it counts as wages, and state guidance says accrued, unused vacation must be paid within five days of a discharge.
Is use-it-or-lose-it vacation legal in New Mexico?
Usually, if the written policy says so. We found no New Mexico statute or agency rule on use-it-or-lose-it policies, so the employer’s written policy usually decides.
