Phoenix Per Diem Rates 2027: Arizona GSA Guide
Learn Phoenix per diem rates for 2027, including seasonal lodging caps, M&IE allowances, first and last-day rules, and Arizona GSA rates.
For business trips to Phoenix in fiscal year (FY) 2027, the GSA lodging ceiling depends on the month: $232 per night in February and March, $122 in June through August, and other limits during the rest of the year. The full-day meals and incidental expenses (M&IE) allowance is $86 throughout the year. Travel managers and finance teams can use these figures to build monthly lodging budgets, establish booking rules, and distinguish federal reimbursement limits from actual hotel prices.
The FY2027 GSA rates apply to covered federal travel from October 1, 2026, through September 30, 2027. Federal contractors follow their applicable contracts and employer policies rather than automatically receiving federal employee allowances. Private employers may adopt GSA figures as travel-policy benchmarks, subject to their own reimbursement arrangements, employment obligations, and tax rules. This guide covers the Phoenix and Scottsdale schedule, Arizona locality differences, meal deductions, hotel-rate availability, and ways to manage per diem-based corporate travel.
Key Takeaways
- Phoenix lodging: The FY2027 lodging cap is $165 in October through January and September, $232 in February and March, $171 in April and May, and $122 in June through August.
- Meals and incidentals: Phoenix has a full-day M&IE allowance of $86, consisting of $22 for breakfast, $23 for lunch, $36 for dinner, and $5 for incidentals.
- Travel days: Eligible federal travelers generally receive 75% of M&IE on the first and last travel days, or $64.50 in Phoenix, before applicable furnished-meal deductions.
- Locality boundaries: The Phoenix/Scottsdale GSA locality covers Maricopa County, including Phoenix, Scottsdale, Tempe, Mesa, Chandler, and Glendale. The official temporary duty (TDY) work location generally determines the federal rate.
- Hotel availability: In Engine's per diem study, 64.6% of Phoenix hotel rates shown in searches and 47.4% of Scottsdale rates met the corresponding FY2027 lodging ceiling. These are retrospective comparisons of displayed rates, not percentages of completed bookings.
- Other Arizona areas: GSA's FY2027 files list five Arizona nonstandard localities. Sedona reaches a $282 lodging ceiling in March and April, while the statewide standard for places outside the named areas is $113 for lodging and $68 for M&IE.
Understanding Phoenix Per Diem Rates for FY2027
The General Services Administration (GSA) sets lodging and M&IE reimbursement rates for covered federal travel within the continental United States. Its published per diem rates distinguish the allowable expense categories; the lodging cap is not a promise that a room will be available at that price or a payment automatically made at the maximum.
What a Per Diem Rate Covers
- Lodging: Under the ordinary federal reimbursement method, employees receive their actual and necessary lodging costs, up to the applicable nightly ceiling. Eligible lodging taxes are addressed separately.
- Meals and incidental expenses: M&IE is a daily allowance based on the designated locality, subject to first- and last-day adjustments and deductions for certain furnished meals. The GSA meal breakdown allocates the daily amount among meals and incidentals.
For federal travelers, unused M&IE cannot be transferred to a lodging allowance, and unused lodging capacity cannot be added to M&IE. Private companies can structure their own policies within applicable legal, contractual, and tax requirements.
Why Phoenix Has Seasonal Lodging Limits
GSA uses hotel average daily rate data and seasonal patterns when setting nonstandard-area lodging rates. Phoenix's FY2027 schedule contains five consecutive date periods and four distinct nightly ceilings. The February and March ceiling is $110 higher than the June through August ceiling, but that difference is between reimbursement maximums, not verified room-price savings.
Seasonality also matters for conference and event planning. MLB's 2027 schedule starts Cactus League spring training on February 19, within Phoenix's February and March rate period. The National Weather Service's 2025 review reports average daily highs in Phoenix of 106.2 degrees F in June, 107.6 degrees F in July, and 109.3 degrees F in August. Neither the event schedule nor these temperature observations establishes a specific cause for GSA's monthly ceilings.
Phoenix and Scottsdale Lodging Rates by Month
The official Phoenix/Scottsdale FY2027 schedule applies to the Maricopa County locality. Under the federal work-location rule, the rate normally follows the TDY assignment location, even when a traveler stays in a different city. An agency can authorize an appropriate alternative lodging locality under its rules.
FY2027 Monthly Lodging Schedule
Source and calculation: GSA's Phoenix rate schedule. The final column adds the nightly lodging maximum to the full-day M&IE amount. It is an illustrative ceiling calculation, not a guaranteed daily payment. Actual eligible lodging cost, taxes, travel-day adjustments, provided meals, and other reimbursement conditions affect what is payable.
How to Interpret the Seasonal Periods
- February and March: At $232, these months have the highest FY2027 lodging ceiling in Maricopa County. The illustrative lodging-plus-full-day-M&IE figure is $318.
- April and May: The $171 lodging ceiling creates a different budgeting threshold for spring conferences, client meetings, and team offsites.
- June through August: The $122 ceiling is $110, or approximately 47.4%, below the $232 February and March maximum. It does not establish a 47.4% discount on an actual hotel reservation.
- October through January and September: The $165 ceiling is useful as a recurring baseline for travel budgeting across those five months.\\
The GSA lodging limits exclude room taxes. For eligible federal travel within the continental United States, taxes on reimbursable lodging costs can be reimbursed separately, subject to applicable agency procedures.

How Often Phoenix-Area Hotel Rates Meet the GSA Cap
Government reimbursement ceilings and available hotel prices answer different questions. Engine's FY2027 per diem study compares hotel rates displayed in Engine searches with the applicable FY2027 GSA lodging caps, including the monthly limits for the Phoenix/Scottsdale locality.
Phoenix Metro Rate Findings
Source and methodology: Engine Data Lab. The study analyzed nightly hotel rates shown in Engine searches for check-ins from October 2025 through September 2026 and compared them with the FY2027 GSA lodging caps for the matching calendar month. For stays crossing a seasonal rate boundary, the analysis applied the cap for the check-in month to the displayed nightly price. Displayed rates include fees paid at the hotel, such as resort fees, and exclude taxes. The percentages describe rates shown in searches, not rates paid by travelers or completed bookings. A hotel class qualifies when at least 70% of its displayed rates meet the cap and the lower classes with sufficient data meet that threshold. Classes without sufficient data are not treated as evidence that the cap covers those classes. Historical search results do not guarantee future availability or prices.
These figures show why the same Maricopa County lodging limit can produce different booking choices in Phoenix, Scottsdale, Mesa, and Chandler. Teams planning flexible office visits or events can compare available hotels across suitable locations while keeping the actual work site, commute, and company travel policy in view.
M&IE Breakdown for Phoenix and Scottsdale
The Phoenix/Scottsdale full-day M&IE rate is $86 throughout FY2027. Lodging ceilings vary by month, but the published meal and incidental allocations do not.
Daily Meal and Incidental Allocations
Source: GSA M&IE breakdowns. Incidental expenses include certain tips for porters, baggage handlers, and hotel staff. Transportation and laundry are not included in this listed $5 incidental allocation, although separate rules may govern other eligible travel expenses.
First and Last Travel Days
Under the federal travel-day rule, eligible travelers generally receive 75% of the locality's full-day M&IE amount on the first and last calendar days of a trip. For Phoenix, the calculation is $86 x 75% = $64.50 before applicable furnished-meal deductions. This reduction affects M&IE rather than reducing the nightly lodging ceiling.
Deductions for Provided Meals
When the government furnishes meals or a registration fee includes them, 41 CFR 301-11.21 generally requires the relevant meal allocations to be deducted, subject to regulatory exceptions. The following examples assume an otherwise eligible full $86 M&IE day.
Sources and calculation: GSA's meal allocations and the furnished-meal rule. Each remaining amount equals $86 less the relevant meal allocations.
On the first or last travel day, the full allocated amount for each qualifying furnished meal is deducted from the reduced $64.50 allowance. For example, furnished lunch and dinner result in $64.50 - $23 - $36 = $5.50. Deductions cannot bring the payment below the $5 incidental allocation. Complimentary hotel or motel meals and meals supplied by a common carrier generally do not require deductions. Agencies may authorize specified exceptions, including some cases involving official duties or qualifying medical or religious needs.
Arizona GSA Per Diem Localities Compared
Arizona has five named FY2027 nonstandard GSA areas. Other locations use the standard continental U.S. rate. The boundaries matter: Sedona is defined by city limits, while the Phoenix/Scottsdale rate covers Maricopa County.
FY2027 Arizona Lodging and M&IE Summary
Sources and calculation: GSA's FY2027 per diem files, the FY2027 standard-rate bulletin, and the Phoenix/Scottsdale schedule. Combined figures are arithmetic illustrations using the applicable lodging ceiling plus full-day M&IE. They exclude lodging taxes and applicable reimbursement adjustments. Standard CONUS is a residual rate category, not a sixth Arizona nonstandard area.
Important Arizona Scheduling Differences
- Sedona: The $282 lodging ceiling applies in March and April 2027. In April, that maximum is $111 above Phoenix's $171 lodging ceiling. Both are reimbursement maximums, not quoted hotel rates.
- Tucson: The $208 lodging ceiling applies from January through March 2027, while Phoenix reaches its $232 maximum in February and March.
- Grand Canyon/Flagstaff: The $113 lodging ceiling applies from November 2026 through February 2027; the other FY2027 months use $152.
- Kayenta: The $147 lodging ceiling stays constant through FY2027.
- Other Arizona locations: The standard $113 lodging and $68 M&IE figures apply where no named GSA locality covers the work site.
For a multi-city itinerary, the TDY work-location rule remains central. Staying in Flagstaff while performing an assignment in Sedona does not, by itself, switch the applicable federal rate to Flagstaff. Agency authorization can govern use of a different lodging locality.
Corporate Travel Budget Scenarios for Phoenix
Budgets based on GSA ceilings should distinguish maximum reimbursable lodging amounts from hotel prices actually selected. The number of nights in each monthly period can materially affect a company's modeled exposure.
Example: 100 Hotel Nights Across FY2027
Assume an organization expects 20 February and March nights, 20 April and May nights, 30 June through August nights, and 30 nights in the remaining months. Each night is valued at that period's GSA lodging ceiling, with M&IE, taxes, and other costs excluded.
Calculation: The FY2027 GSA ceilings multiplied by the assumed hotel nights total $16,670. Dividing that sum by 100 nights gives a $166.70 weighted lodging ceiling. This is a planning model, not an actual average booked nightly rate or a forecast of hotel spending.
Budget Planning Recommendations
- Model nights by month. Use the appropriate FY2027 seasonal ceiling for each anticipated Phoenix assignment, rather than one annual maximum.
- Separate the spending categories. Keep lodging limits, M&IE eligibility, reimbursable taxes, and other travel expenses distinct in budgets and reimbursement records.
- Compare actual room offers. A lower GSA maximum does not guarantee a lower hotel price. Hotel location, mandatory fees, event schedules, and availability affect the relevant booking choices.
- Account for provided meals. Conference registration packages can change an eligible federal traveler's M&IE reimbursement under the furnished-meal rules.
- Use cost centers and project codes. Structured trip data makes it easier to compare booked lodging costs with an organization's adopted reimbursement policy.
Applying Federal and Company Per Diem Policies
Which Location Determines the Rate?
Under 41 CFR 301-11.4, the TDY or work location generally determines the federal per diem rate. A Maricopa County assignment ordinarily uses Phoenix/Scottsdale limits even if the lodging is in Tempe or Mesa. When lodging is obtained outside the TDY location, the agency may approve a different locality's rate if doing so is advantageous to the government.
The applicable calendar date also matters. Trips crossing a seasonal boundary can involve different lodging limits on different nights. Private employers may adopt location-specific and month-specific limits, but the federal TDY work-location rule does not automatically determine private-sector tax treatment. For the IRS's regular federal per diem and standard meal allowance methods, the relevant locality is generally where the traveler stops for sleep or rest.
Lodging Reimbursement and Room Taxes
The ordinary federal rule reimburses actual and necessary lodging expenses up to the applicable ceiling. Consider two simplified October 2026 examples with a $165 Phoenix lodging maximum and no special authorization:
- Eligible room expense of $150: The lodging reimbursement is $150, not the full $165 maximum.
- Eligible room expense of $250: Ordinary lodging reimbursement is capped at $165. The $85 above that ceiling is not covered under the usual method without an approved exception.
These examples exclude taxes. Under 41 CFR 301-11.16, eligible lodging taxes in the continental United States can be reimbursed separately, limited to taxes attributable to reimbursable lodging expense.
Agency-Authorized Actual Expenses
If the applicable per diem is insufficient, 41 CFR 301-11.17 permits a federal traveler to seek agency authorization for actual-expense reimbursement up to 300% of the applicable maximum per diem amount, which includes lodging and M&IE, or a lower limit set under agency policy. This is an actual-expense authorization, not an automatic tripling of the nightly lodging ceiling. Reimbursement remains limited to allowable actual expenses. Under 41 CFR 301-11.23, actual-expense claims require itemized expenses and lodging receipts regardless of amount. Approval is discretionary and typically occurs in advance. An agency may also authorize an alternative lodging-locality rate when it is advantageous to the government.
Situations that may warrant agency consideration include limited compliant lodging availability, business-critical travel during a major event, or documented accommodation needs. The regulation does not make these circumstances automatic exceptions.
Federal Contractors and Private Employers
GSA establishes per diem rates for federal employees on official travel. Federal contractors' reimbursement terms depend on their contracts and employer policies. Private employers may use the published rates as benchmarks for booking caps or expense allowances, subject to their applicable obligations.
For tax purposes, the IRS accountable-plan guidance distinguishes qualifying business expense reimbursements from taxable payments. Eligible per diem methods can simplify substantiation of certain expense amounts, but applicable rules still require a business connection, appropriate records, and proper treatment or return of excess allowances. Engine's corporate travel policy template can provide a starting structure for documenting employee eligibility, monthly rate limits, and approval processes.
How Engine Helps Manage Phoenix Per Diem-Based Travel
Engine is a modern travel management platform for companies booking and managing business travel. Its booking-time policy controls, approvals, reporting, centralized billing, and group lodging services support travel managers and finance teams applying location-specific budgets across office visits, conferences, sales travel, and team events.
Travel Policy Enforcement: Location-Based Nightly Rate Caps
Engine Travel Policy Enforcement allows administrators to configure fixed or tiered nightly lodging limits, including location-based rules, and assign policies to all members, selected employees, or departments. Engine evaluates configured rules during the booking process, so teams can apply company-adopted Phoenix limits to available room choices.
The travel policy settings also let administrators choose whether a hotel rate cap applies to the total cost including taxes and fees. Companies using GSA's pre-tax lodging ceilings can align their configured thresholds with their written policy, including updates when seasonal rates take effect.
Engine Approvals: Booking Blocks and Exception Workflows
Engine Approvals supports three documented responses to out-of-policy travel:
- Not Allowed: Prevents an out-of-policy reservation from being completed.
- Allowed with Reason: Lets the traveler proceed after providing a reason.
- Allowed with Approval: Routes the exception to configured administrators or department managers for an approval decision before booking.
These options support both defined spending limits and an organized decision path for trips where a business need justifies an exception under the company's rules.
Travel Dashboards and Reporting: Nightly Rates and Cost Codes
Engine travel dashboards help finance teams analyze travel spending, average nightly rates, and adherence to configured policies. Reports can be filtered by traveler, booker, department, city, hotel, and date range. Custom fields connect booking information to general ledger codes, cost centers, and project IDs, with CSV and PDF exports available for reconciliation.
For a recurring Phoenix travel program, these capabilities bring booked hotel costs and company policy data into the same reporting workflow, supporting department-level reviews and seasonal budgeting.
DirectBill: Credit Line and Consolidated Invoices
With Engine DirectBill, Engine extends an approved line of credit, pays eligible hotels, and provides the company with a consolidated invoice after stays, according to the account's billing terms. Itemized billing records and company cost fields support reconciliation and assignment of travel costs to the right projects or departments.
Engine's billing tools also provide centrally accessible statements, folios, and exportable records to help finance teams organize the documentation associated with their travel programs. Credit approval and the applicable account agreement govern DirectBill.
Engine Group Room Blocks: Sourcing for Nine or More Rooms
Engine Group Room Blocks routes requests for nine or more rooms to the Groups team for sourcing, hotel proposals, negotiations, and room-block coordination. This supports conferences, team offsites, sales meetings, and other Phoenix programs involving multiple travelers. The Groups team can coordinate proposals based on event dates, property availability, and the organization's lodging budget.
The Engine Groups service and Engine's core booking platform are free to use. No platform fees, no membership fees, no agent-assist fees, no contracts, no minimum spend. Individual hotel reservations and negotiated group room-block arrangements remain subject to their booking or contract terms.

Frequently Asked Questions
Does the Phoenix per diem rate apply to Tempe, Mesa, Chandler, and Scottsdale?
Yes, for an eligible federal assignment whose TDY work location is in Maricopa County. The Phoenix/Scottsdale GSA locality covers the county, so its seasonal lodging ceilings and $86 full-day M&IE allowance generally apply. A hotel address alone does not change the work-location rule, although an agency-approved alternative locality may apply.
Are the $208 to $318 combined amounts guaranteed daily reimbursements?
No. Those figures add a monthly lodging ceiling to the $86 full-day M&IE allowance for illustration. Actual lodging reimbursement is based on eligible expense up to the ceiling, and travel-day rules, furnished meals, taxes, and other conditions affect the payable amount. Unused M&IE and lodging allowances cannot be combined across categories.
What happens when a Phoenix hotel costs more than the GSA lodging ceiling?
A covered federal traveler may seek agency authorization for actual-expense reimbursement up to 300% of the applicable maximum per diem, including lodging and M&IE, or a lower approved limit. This is not an automatic increase to the lodging-only maximum. Approval is discretionary and typically granted in advance. Private-sector travelers follow their company's travel policy and exception process.
Are Phoenix hotel taxes included in the lodging per diem?
No. The GSA nightly lodging ceiling excludes lodging taxes. For eligible federal travel in the continental United States, taxes attributable to reimbursable lodging costs may be paid separately as miscellaneous travel expenses under 41 CFR 301-11.16.
How much M&IE applies on the first or last travel day?
The federal first/last-day amount is 75% of Phoenix's $86 full-day M&IE, or $64.50, before qualifying provided-meal deductions. The nightly lodging ceiling is not prorated solely because it is the first or last travel day.
What happens if a conference includes lunch and dinner?
For an otherwise eligible full M&IE day, the GSA allocations deduct $23 for lunch and $36 for dinner, leaving $27 from the $86 allowance. On a first or last travel day, the same qualifying deductions leave $5.50 from $64.50. The furnished-meal regulation includes exceptions for certain hotel meals, carrier meals, and qualifying circumstances approved by an agency.
