OCONUS Per Diem and Allowances Explained

Who sets OCONUS per diem rates, how per diem differs from COLA and Living Quarters Allowance, and the distinction that matters most to a contractor: these are federal traveler and employee entitlements, not something a contractor employee automatically receives.

By The Recruitmint Team

OCONUS per diem is the maximum daily reimbursement for lodging and meals on official travel outside the continental United States. Three bodies set these rates: GSA for the contiguous states, the Department of Defense for Alaska, Hawaii and outlying areas, and the Department of State for foreign areas. These are government rates, not automatic contractor pay.

Who actually sets OCONUS per diem rates

FAR 31.205-46, the clause governing travel costs on government contracts, names all three authorities directly. It states that lodging, meals and incidental expenses "shall be considered reasonable and allowable only to the extent that they do not exceed on a daily basis the maximum per diem rates in effect at the time of travel," and it defines those maximums by area.

AreaWho sets the rateGoverning regulationWhere to look it up
Contiguous United States (CONUS)General Services Administration (GSA)Federal Travel Regulation (FTR)GSA per diem rates
Alaska, Hawaii, and outlying US areas (non-foreign OCONUS)Department of DefenseJoint Travel Regulation, Volume 2, DoD Civilian Personnel, Appendix ADefense Travel Management Office (DTMO)
Foreign areasDepartment of StateStandardized Regulations (Government Civilians, Foreign Areas), Section 925 (DSSR)State Department foreign per diem lookup

The GSA page states its role plainly: it establishes "the per diem rates that federal agencies use to reimburse their employees for lodging and meals and incidental expenses incurred while on official travel within the continental United States." Foreign rates come from the State Department's Office of Allowances, published monthly as separate lodging and meals-and-incidental-expenses components plus a combined daily rate, searchable by country or post name. For Alaska, Hawaii and US territories, the Defense Travel Management Office is the DoD source for both non-foreign OCONUS per diem and the separate OCONUS COLA calculator that readers searching that term are usually trying to find; we are naming it as the correct place to look, not stating any figure it currently shows.

No specific rate for any named post appears anywhere in this guide, because rates change on a regular cycle and the only correct source is whichever authority governs that location.

Per diem, COLA, LQA and hardship pay are not the same entitlement

These four terms get flattened into "OCONUS money" constantly, and a hiring manager who conflates them will misquote an offer. Each has a distinct purpose, a distinct governing regulation, and often a different population it applies to.

Per diem: a travel reimbursement ceiling

Per diem is the maximum daily amount for lodging and meals while someone is on official travel, meaning temporarily away from their permanent duty station. It is governed by the FTR for CONUS, the JTR for non-foreign OCONUS areas, and the DSSR for foreign areas, depending on where the travel occurs. It is built for a traveler, not for someone permanently assigned to a post.

COLA or post allowance: a cost-of-living supplement for people stationed there

Cost-of-living allowance (called post allowance in the DSSR) is a supplement for personnel who are assigned to a location, not passing through it. It sits in the DSSR alongside per diem but answers a different question: not "how much does a trip cost" but "how much more expensive is ordinary living here than at home." It is not a travel reimbursement and does not use the per diem tables.

Living Quarters Allowance: housing costs specifically

LQA covers housing costs for an assigned employee, separate from both per diem and COLA. It also sits in the DSSR, and its eligibility criteria are narrower than the other two. A GAO decision quoting the DSSR states LQA may be granted "to employees recruited outside the United States provided that... the employee's actual place of residence... shall be fairly attributable to his/her employment by the United States Government," or where an agency required the employee "to move to another area" as a condition of employment under DSSR 031.12c. In the case GAO reviewed, LQA was denied because the employee's move, while real, lacked the required management-generated action; a transfer the employee initiated or that happened for reasons other than an agency directive did not qualify. That is the pattern worth internalizing: LQA eligibility is specific and conditional, tied to how and why someone ended up at that post, not a general OCONUS housing benefit.

Danger pay and hardship differential: separate incentive rates

Danger pay and post hardship differential compensate for risk or difficulty at a specific location. They are calculated and published separately from per diem, COLA and LQA, and they answer a third question entirely: not travel cost, not cost-of-living, not housing, but risk and hardship at post.

The distinction that actually matters to a contractor

Say this plainly, because it is the reason this page exists: per diem, COLA, LQA, and hardship pay are entitlements for US government travelers, civilians and servicemembers. A contractor's employee is not automatically entitled to any of them.

FAR 31.205-46 is a cost-allowability rule, not a benefits statute. It tells a contractor what it may bill the government as an allowable travel cost, capping reimbursable lodging, meals and incidentals at "the maximum per diem rates in effect at the time of travel" using the FTR, JTR or DSSR figures as the ceiling. It says nothing about what a contractor must pay its own employee. What that employee actually receives, whether it is a flat OCONUS differential, a housing stipend structured to look like LQA, a per diem-style daily rate, or nothing beyond base salary, is set entirely by the contractor's own compensation plan and by whatever the prime contract or task order actually funds. Two contractors delivering on the same program, at the same post, can pay two entirely different allowance structures to two employees doing similar work, and both can be compliant, because the government regulation is capping what gets billed, not dictating what gets paid.

This is also why a candidate coming from active duty or federal civilian service, and expecting COLA or LQA as a matter of course, is often surprised by a contractor offer. The number they remember from their last assignment was a government entitlement tied to their status as a government employee or servicemember. It does not travel with them into a contractor role unless the contractor has chosen to build something equivalent into the offer.

A worked example, using the structure only

No specific rate for any location is used here. This shows how the ceiling works mechanically, with a labeled hypothetical input, not a real number for any real post.

Suppose a contractor sends an employee on a 10-day temporary duty assignment to a foreign post, and suppose (hypothetically, for illustration only) the applicable combined per diem rate at that post, pulled from the State Department lookup at the time of travel, is $X per day.

  1. Allowable daily ceiling = $X (the published rate for that specific post on that specific date).
  2. Allowable trip ceiling = $X multiplied by 10 travel days.
  3. If the employee's actual lodging and meal costs for the trip come in at or below that ceiling, the full amount is allowable under FAR 31.205-46.
  4. If actual costs exceed the ceiling, only the amount up to $X per day is allowable as a matter of course; anything above it needs the "special or unusual situation" justification the regulation allows, and it is judged against the ceiling applicable to a federal civilian employee, not against what the contractor happens to feel is reasonable.

That is the whole mechanism: pull the real rate for the real location on the real date from the authority that governs it, multiply by days traveled, and treat the result as a ceiling on billable cost, not as a number the contractor's own compensation plan is obligated to match.

A checklist before quoting anything to a candidate

OCONUS allowance conversation: four checks before the offer Pull the current rate from FTR, JTR or DSSR for the exact location State clearly whether company pay references, exceeds, or ignores it Confirm what the contract actually allows with the CO and finance Recheck at renewal: rates are updated on a regular cycle This is a cost-allowability question governed by FAR 31.205-46, not a benefit a search firm sets.
StepWhat to checkWhy it matters
Pull the current rateGet the live rate for the exact location from GSA, DTMO, or the State Department lookup, not a memorized figureRates change on a regular cycle; last quarter's number is not this quarter's number
State the relationship to the government rateSay plainly in the offer whether company pay references the government rate, exceeds it, or is unrelated to itCandidates coming from federal service often assume the government figure carries over automatically
Confirm allowability with the CO and financeCheck what the specific contract or task order actually funds before the candidate conversationFAR 31.205-46 caps what is billable; it does not obligate a specific payment structure
Recheck at renewalRe-pull the rate before extending or renewing an assignmentA rate confirmed at hire is not guaranteed to hold through the life of the assignment

Which roles this affects most

Inside the published Government Contracting category, this comes up hardest for OCONUS / International roles, Logistics, Skilled Trades, and Operations, since these are the roles most likely to involve assignment to a foreign or non-foreign OCONUS post rather than a single domestic trip. It is worth saying directly: we run searches for these roles across government contracting and OCONUS positions, including cleared and linguist searches under an SDVOSB framework, but we do not set, administer or advise on compensation, allowances or cost allowability. That determination sits with the contracting officer, finance, and the specific contract terms, not with a search partner.

For contractors weighing whether an OCONUS role should be staffed as an employee or through another structure, the distinction between employer of record and contractor arrangements is a related question worth working through before the allowance conversation even starts.

The short version

OCONUS per diem is a government reimbursement ceiling, set by GSA for the contiguous states, DoD for Alaska, Hawaii and outlying areas, and the State Department for foreign posts under FAR 31.205-46. COLA, LQA, and hardship or danger pay are separate DSSR entitlements for assigned government personnel with their own eligibility rules. None of these are automatic for a contractor's employee: FAR 31.205-46 caps what a contractor may bill, it does not set what a contractor must pay, and that gap is exactly where a hiring manager needs to be explicit before quoting anything to a candidate.

FAQ

Does a government contractor employee get OCONUS COLA?

Not automatically. COLA (post allowance in the DSSR) is an entitlement for US government civilians assigned to a post, governed by the DSSR. A contractor's employee is paid according to their employer's own compensation plan and whatever the contract actually funds; they may receive something structured similarly, but it is not the same entitlement and does not attach to the job simply because the location matches a government post.

Where do I find the current per diem rate for a specific post?

It depends on the location. For the contiguous United States, use the GSA per diem rates page. For foreign areas, use the State Department's foreign per diem lookup, searchable by country or post. For Alaska, Hawaii, and outlying areas, the Defense Travel Management Office publishes the applicable non-foreign OCONUS rates and the OCONUS COLA calculator. FAR 31.205-46 is the clause that names all three as the governing authorities.

Is LQA the same as per diem?

No. Per diem is a travel reimbursement ceiling for lodging and meals on official travel, governed by the FTR, JTR, or DSSR depending on area. LQA covers housing costs specifically for an employee assigned to a post, governed by the DSSR, and its eligibility is conditional on how the employee came to be at that post, not a general travel benefit.

Can a contractor bill the government more than the per diem ceiling?

Only in special or unusual situations, and only up to the ceilings applicable to federal civilian employees, per FAR 31.205-46. Anything above the published maximum needs specific justification and is not routinely allowable.
