Overview
This Per Diem Request Form template is built to collect the details finance needs to approve or calculate a travel allowance: request type, trip purpose, approval reference, traveler and destination, trip dates, overnight stays, lodging and meal provisions, incidentals, and payment details. It is designed for organizations that reimburse travel using per diem rules, GSA-based rates, or a documented internal policy.
Use it when a traveler needs reimbursement after a trip or an advance before departure, and when the amount depends on destination, duration, and whether lodging or meals were already provided. The structure supports validation and conditional logic, such as showing lodging fields only when the lodging location differs from the destination city or asking for special rate notes when a conference meal changes the allowance.
Do not use this template for itemized expense reports, mileage-only claims, or travel bookings that do not involve per diem. It is also not the right fit if your policy requires highly detailed receipts for every expense category. Keep the form focused on minimum necessary data, with clear required versus optional fields and a submission confirmation that explains what happens after the traveler submits the request.
Standards & compliance context
- Keep the form aligned with GDPR data minimization by collecting only the traveler and trip details needed to process the request.
- If the form is used in a public-facing workflow, ensure WCAG 2.1 AA accessibility with clear labels, keyboard navigation, and readable validation messages.
- Maintain an audit trail for approvals and rate decisions so finance can show how the per diem amount was determined.
- If the form is used for employee travel tied to reimbursement, use clear consent and attestation language that confirms the traveler’s information is accurate.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.

How to use this template
- 1. Set the request type, approval reference, and payment method options to match your travel policy and downstream finance workflow.
- 2. Configure traveler, department, destination, and trip date fields with the correct validation so dates, counts, and location data are entered in structured form.
- 3. Add conditional logic for lodging and meal questions so the form only asks about provided meals, separate lodging locations, and special rate notes when those details affect the calculation.
- 4. Route the submission to the manager, budget owner, or finance reviewer who will confirm eligibility, rate treatment, and any exceptions before payment is issued.
- 5. Review the completed request against policy, then approve, reject, or send back for correction with a clear note on missing fields or unsupported amounts.
- 6. Store the submission in an audit trail so the organization can show how the per diem amount was determined and who approved it.
Best practices
- Mark every required field clearly and keep optional fields limited to the details finance truly needs.
- Use date pickers for departure and return dates, numeric inputs for overnight stays and travel days, and avoid free-text fields for structured values.
- Show lodging and meal questions only when they affect the allowance, using progressive disclosure to keep the form short and relevant.
- Include a plain-language line that explains what happens after submission, including who reviews the request and when payment is expected.
- Collect only the minimum necessary PII, and avoid asking for sensitive identifiers unless your payment process truly requires them.
- Use the special rate notes field for exceptions such as conference meals, shared lodging, or policy overrides, not for general comments.
- Validate that return date is not earlier than departure date and that overnight stays align with the trip duration.

Common use cases
Frequently asked questions
What is this Per Diem Request Form used for?
This form is used to request a per diem reimbursement or advance for business travel. It collects the trip purpose, destination, dates, lodging details, and payment method so finance can calculate the correct allowance. It is best for trips where per diem is based on policy or GSA rates rather than itemized receipts.
When should an employee submit this form?
Submit it before travel when an advance is needed, or right after travel when the request is for reimbursement. If your organization requires pre-approval, the approval reference should already exist before the form is sent. For trips with multiple destinations or partial-day travel, submit once the itinerary is final.
Who should complete and approve the form?
The traveler usually completes the request, and a manager or budget owner approves it before finance processes payment. In some organizations, a travel coordinator or HR operations partner may help with routing. The approver should confirm the trip purpose, dates, and whether lodging or meals were provided.
How does this template handle GSA-based rates or special cases?
The form includes fields for destination, lodging location, and special rate notes so reviewers can apply the correct rate rules. If lodging is outside the destination city or meals are provided by a conference, those details can change the per diem calculation. Use the notes field to explain exceptions, but avoid collecting extra PII that is not needed for payment.
What are the most common mistakes with per diem requests?
Common issues include missing trip dates, unclear destination details, and forgetting to note whether lodging or meals were provided. Another frequent problem is using free-text notes instead of structured fields for dates, counts, and amounts. Those mistakes slow validation and can lead to incorrect reimbursement or advance amounts.
Can this form be customized for different travel policies?
Yes. You can add conditional logic for domestic versus international travel, conference travel, union rules, or department-specific approval paths. You can also rename fields to match your policy language, as long as required and optional fields stay clear and the form only collects data you actually use.
Does this template integrate with expense or payroll systems?
It can be connected to expense management, payroll, or ERP workflows through form automation or an API. Common integrations include approval routing, employee directory lookup, and payment status updates. Keep the form focused on the data needed for the handoff so downstream systems do not receive unnecessary PII.
How should we roll this out across the company?
Start with one policy owner, one finance reviewer, and a small pilot group of frequent travelers. Confirm the field labels, validation rules, and approval steps before publishing broadly. A short rollout guide helps travelers know when to use the form, what documents to attach, and what happens after submission.
