Ever wonder how much state workers get paid to travel for their job? Turns out, there’s an actual law for that.
New Mexico has specific rules about per diem, or daily travel pay, for public employees. Stay with me here. This one gets more interesting than it sounds.
What Is Per Diem?
Per diem is a Latin phrase. It just means “per day.” So simple!
In plain terms, per diem is money an employer gives you for daily expenses while traveling for work. It covers things like meals, lodging, and small extra costs. You don’t have to save every receipt to get paid.
Wondering if this applies to you? It depends on who you work for. Let’s break it down.
Basic Per Diem Laws in New Mexico

The Per Diem and Mileage Act
New Mexico’s rules come from a law called the Per Diem and Mileage Act. You’ll find it in state law under Sections 10-8-1 through 10-8-8.
This law sets the rules for state and local government workers. It covers salaried employees, non-salaried public officers, and board members too. Basically, if you work for New Mexico government, this law probably applies to you.
Honestly, this is the part most people miss. This law does NOT apply to private companies. If you work for a regular business, your per diem depends on your employer’s own policy, not this state law.
Who Gets Per Diem Pay?
Public officers and employees traveling for official state business qualify. This includes people traveling within New Mexico and outside the state too.
Not sure what counts as “traveling”? The law says your home is the area within 50 miles of where you legally live. Travel outside that zone for work usually qualifies for per diem.
Here’s a quick tip. Your “designated post of duty” matters too. That’s basically your regular work location. Per diem generally kicks in once you travel away from both your home and your normal job site.
New Mexico Per Diem Rates for 2026
Okay, this one’s important. Let’s talk numbers.
For fiscal year 2026, which runs from July 2025 through June 2026, New Mexico set new overnight per diem rates. In-state overnight travel pays $180 per day. That’s up from $166 the year before.
Traveling to Santa Fe County? That area has its own special rate. It’s $249 per day for FY26, since Santa Fe tends to be pricier for lodging.
Out-of-state overnight travel also pays $180 per day for FY26. International travel pays even more, at $298 per day in U.S. dollars.
Sound complicated? It’s actually not. These flat rates cover lodging, meals, and small incidentals all in one payment. No itemizing needed.
Quick Rate Snapshot for FY26 (Overnight Travel)
In-state travel pays $180 daily. Santa Fe County travel pays $249 daily. Out-of-state travel pays $180 daily. International travel pays $298 daily.
What About Same-Day Trips?

Not every work trip means an overnight stay. Sometimes you’re back home the same day. New Mexico has rules for that too.
If you’re gone less than 2 hours, you get nothing. That makes sense, right? A quick trip barely counts as travel.
Gone between 2 and 6 hours? You get $25. Between 6 and 12 hours? That’s $50. Gone 12 to 24 hours without an overnight stay? You’ll receive $70.
Pretty straightforward, honestly. The longer you’re out, the more you get.
Meal Rates for Actual Expense Reimbursement
Here’s where things get a little different. Some employees choose actual expense reimbursement instead of the flat per diem rate.
Wait, it gets better. If you go this route, New Mexico caps meal reimbursement at $70 per day for FY26. This applies whether you’re traveling in-state or out-of-state.
Trust me, this works differently than per diem. With actual reimbursement, you save your receipts. Your total meal costs just can’t go over that daily cap.
Lodging Limits and Special Approvals

Choosing actual expenses instead of the flat rate? Your lodging is limited too.
For FY26, overnight lodging using actual costs is capped at $350 per night. Need something above that limit? You’ll need approval first from your agency head or the chairperson of your governing board.
This part can be tricky, honestly. Skipping that approval step could mean your extra costs don’t get paid back.
Mileage Reimbursement Rules
Per diem isn’t just about meals and hotels. Driving your own car for work matters too.
For 2026, New Mexico set the mileage rate at 100% of the previous year’s IRS rate. That works out to 70 cents per mile for privately owned vehicles this year.
Flying your own plane for state business? That’s a real thing some employees do. Private aircraft mileage gets reimbursed at a much higher rate, since flying costs more than driving.
Think of it like this. Mileage pay is basically covering wear and tear, gas, and insurance on your personal ride. It’s not extra income. It’s reimbursement for what the trip actually costs you.
Penalties and Consequences for Misuse

Now, here’s where things get serious. Per diem isn’t free money. Misusing it can cause real problems.
New Mexico law includes penalties for false swearing on an official travel voucher. That means if you lie about your travel to collect per diem you didn’t earn, you could face legal consequences beyond just losing the money.
Think of it like a fraud charge, but tied specifically to government travel funds. It’s less common than other financial crimes, but still no joke. Agencies take these vouchers seriously because they involve public tax dollars.
Employees who submit false travel claims can also face job discipline. That might mean a written warning, suspension, or even losing your job, depending on how serious the violation is.
Special Circumstances Worth Knowing
Not every situation fits the standard rules. New Mexico’s law carves out some exceptions.
State legislators follow different rules entirely. They’re not covered under the general Per Diem and Mileage Act the same way regular state employees are. Instead, lawmakers get their own per diem and mileage schedule set separately.
Employees of public colleges and universities also have some different provisions. Personally, I think this makes sense. Higher education institutions often have unique travel needs compared to a typical state office.
Here’s another one people miss. If you attend more than one board or committee meeting on the same day, you can’t collect per diem for each meeting separately. You only get paid once for that day, even with a packed schedule.
How Per Diem Actually Gets Paid

Wondering how the process works in real life? Let’s walk through it.
First, you request approval to travel for state business. Once approved, you keep track of your travel dates and destination.
After your trip, you’ll submit a travel voucher. This document lists your dates, mileage, and which per diem rate applies to your trip.
Your agency reviews the voucher and processes payment. Simple enough, right? The key is submitting accurate information, since false claims carry real penalties.
Private Sector Per Diem: A Different Story
Quick pause here, because this trips people up a lot.
If you work for a private company in New Mexico, the state’s Per Diem and Mileage Act doesn’t cover you. It’s more common than you think for people to assume otherwise.
Private employers set their own travel reimbursement policies. There’s no New Mexico state law forcing businesses to pay per diem to private employees.
That said, federal law still matters here. Under the Fair Labor Standards Act, your required work expenses can’t push your effective pay below New Mexico’s minimum wage. So while there’s no per diem mandate, there’s still a wage floor protecting workers.
Many private companies choose to follow GSA federal rates anyway. It just makes budgeting predictable and feels fair to employees. But legally, it’s their choice, not a requirement.
How to Comply With Per Diem Rules

If you’re a public employee, here’s what you need to do to stay on the right side of these rules.
Keep your travel dates and times accurate. Don’t round up hours to hit a higher reimbursement tier. That’s the kind of thing that turns into a real problem later.
Get written approval before choosing actual expense reimbursement over the standard per diem rate. Skipping this step could leave you covering extra costs yourself.
Save documentation for anything involving actual expenses, especially lodging above the cap. Agencies will ask for it if your costs run high.
Double check which rate applies to your destination. Santa Fe County has its own special rate, remember? Using the wrong rate could mean a delayed or corrected payment.
