What a Finance Per Diem Letter Is and When it’s Used

A Finance Per Diem Letter documents an employee or contractor request for per diem reimbursement or advance and explains the employer’s per diem policy, allowable rates, and substantiation requirements. It typically identifies traveler name, dates and purpose of travel, per diem rate applied, estimated total, and any attached receipts or itinerary. Organizations use the letter to support internal approval, payroll processing, tax substantiation, and audit trails. When combined with an accountable plan, the Finance Per Diem Letter supports tax-compliant reimbursements and provides a single record aligning business purpose with payment.
