As a major hub for the aerospace, technology, and tourism industries in the American Southwest, Phoenix is a key destination for business travel. For any organization with employees traveling to Phoenix, a clear and efficient strategy for managing expenses is essential for financial control and operational success.

Per diem, a daily allowance for lodging, meals, and incidental expenses, is the most common method for handling travel reimbursements. This guide offers a comprehensive look at the federal per diem rates for Phoenix, clarifies important Arizona laws, and shows how you can automate the entire process.

Phoenix Per Diem Rate

Per diem rates for official travel in Phoenix are set by the U.S. General Services Administration (GSA). These federal rates are mandatory for federal employees and serve as a common benchmark for private sector companies looking to create an IRS-compliant reimbursement policy.

For Fiscal Year 2025 (October 1, 2024, to September 30, 2025), key rates for the Phoenix area are broken down as follows:

Phoenix Metro Area

As a major travel destination, the city of Phoenix and all of Maricopa County have their own specific Non-Standard Area (NSA) rates with significant seasonal variations.

  • Phoenix / Scottsdale (Maricopa County):
    • M&IE: $86 per day
    • Lodging: Highly seasonal, with peak winter/spring rates of $229 per night (Feb-Mar) and rates as low as $113 per night in the summer.
    • The first and last day of travel, the M&IE rate is $64.50.

Standard CONUS Rate

For any county in Arizona not specifically listed by the GSA, the standard CONUS rate applies. For FY 2025, this rate is $178 ($110 for lodging and $68 for M&IE).

Some Important Phoenix Per Diem Laws

For private employers in Arizona, state law provides flexibility, making the company's own policy the most important factor in managing travel expenses.

  • Reimbursement As A Matter of Policy: Arizona state law does not require private employers to reimburse employees for business-related travel expenses. Therefore, establishing a clear, fair, and consistently enforced travel policy is essential for managing employee expectations and avoiding potential disputes.
  • Minimum Wage Protections: A critical legal consideration is that any unreimbursed, necessary business expense cannot cause an employee's effective earnings to drop below the state's minimum wage. This creates a legal floor for reimbursement.
  • Arizona's State Employee Travel Regulations: The State of Arizona has its own detailed travel policy for its public employees, outlined in the State of Arizona Accounting Manual (SAAM). This policy sets specific reimbursement rates and rules that are separate from the GSA per diem system.

Phoenix Per Diem Laws vs Federal Law

It's important to understand the distinction between the federal GSA system and Arizona state law.

Primary Applicability

  • Federal Law (GSA): Mandatory for all U.S. federal government employees on official business in Phoenix. It is also the most common standard used by private businesses for an IRS-compliant accountable plan.
  • Arizona State Law: Does not mandate expense reimbursement for private employers (beyond minimum wage protections). The primary legal considerations are the employer's own policies.

Rate Setting and Usage

  • Federal Law (GSA): Sets specific, non-negotiable per diem rates for Phoenix that federal agencies must use.
  • Arizona State Law: Does not set or regulate per diem rates for private companies. Businesses are free to set their own reimbursement rates or policies, though using GSA rates is a common best practice.

Legal Focus

  • Federal Law (GSA): Aims to create a uniform, cost-controlled system for federal travel.
  • Arizona State Law: Relies on the agreements made between an employer and employee, giving businesses flexibility while holding them accountable to their own written policies.
