Purpose & Scope
Explain who is covered, what travel qualifies, and the policy’s objectives, including tax treatment and interaction with other expense rules.
A formal per diem policy reduces inconsistent reimbursements, eases payroll processing, and supports IRS substantiation requirements. It protects the organization from accidental taxable wages, speeds approvals, and provides a consistent framework for managers and traveling employees to follow.
This policy is typically prepared and maintained by HR in coordination with payroll and finance; it is used by managers and traveling staff to request or approve per diem payments.
Clear role definitions reduce processing delays and make it easier to trace approvals and payments during audits.
The HR Director typically approves policy language, exceptions framework, and final governance. They coordinate with Legal and Finance to ensure tax and recordkeeping compliance, and they sign off on major policy changes.
The Payroll Manager authorizes periodic disbursements, confirms withholding treatment where required, and ensures per diem entries reconcile with payroll records and expense ledgers for audit trails.

Specify daily allowances by location or tier (domestic, high-cost cities, international) and cite the rate source or company matrix used to set amounts.
Define minimum travel duration, business purpose requirements, and employee classes (full-time, contractors, temporary) eligible for per diem.
State whether receipts are required, what supporting information must be submitted, and any alternate substantiation method used for IRS compliance.
Describe routing for pre-approval, manager sign-off, and payroll verification, including timelines for submission and reimbursement.
Outline exception handling, audit sampling frequency, recovery of overpayments, and disciplinary measures for noncompliance.
