Checklist: Fall Reimbursement Process Readiness and T&E Prep

As fall approaches, finance and accounting teams need reimbursement processes that are audit-ready and compliant before volume picks up. This checklist covers the details that most commonly trip up certification reviews — routing gaps, per diem miscalculations, documentation holes, and year-round maintenance habits that make or break an audit response.

Reimbursement routing / per diem / IRS mileage

Reimbursement routing process essentials

Pre-fall audit checklist:

• Document your approval hierarchy in writing — Create a matrix showing dollar thresholds, approval levels, and backup approvers. Include specific scenarios: instructional supplies under $500 require Principal approval; specialized equipment between $2,000 and $10,000 require the Business Manager/CFO; all expenditures exceeding $50,000 require formal Board approval.

• Verify routing rules handle edge cases — Test your system for: staff and building changes that occurred over the summer, employees on leave who submitted expenses before departure, and cross-departmental projects with split funding sources.

• Establish maximum reimbursement timeframes — Set clear policies for how long after an expense occurs it can be submitted (common standard: 60–90 days). Document the exceptions process for late submissions.

• Create a stuck-expense protocol — Define what happens when an approver does not respond within X days. How do you monitor? Who gets notified? When does it escalate?

Per diem compliance deep dive

Critical but commonly missed items:

• Verify your per diem rates match your Board Policy or current GSA schedules — Rates may change annually. Download the current fiscal year rates and compare against your system settings. Pay special attention to high-cost localities that frequently change.

• Document your partial day calculation method — Be explicit: Do you prorate by quarter-day, half-day, or use the federal method (75% for first and last day of travel)? Apply consistently.

• Address the local travel gray area — Define in writing when per diem applies. Is it based on distance from home office, overnight stay requirement, or time away from home base? Example: Per diem applies when travel exceeds 50 miles from primary work location AND requires overnight stay.

• Create a meals-provided deduction schedule — When conferences or clients provide meals, document your deduction approach. Federal standard: breakfast = 20% of daily rate, lunch = 30%, dinner = 50%.

IRS mileage rate compliance

2026 preparation checklist:

• Update rates effective January 1st and July 1st — The IRS enacted a mid-year update to the mileage rate from 72.5 cents to 76 cents. Ensure employees are submitting mileage to the correct rate, and monitor each December for updates.

• Audit your mileage calculation methodology — Verify you are calculating point-to-point business mileage correctly. Document how you handle: trips with multiple stops, personal detours during business travel, and commute-to-temporary-work-location scenarios.

• Address the home mileage question — Document when travel from home qualifies as business mileage versus personal commute.

• Create mileage documentation standards — Require: date, business purpose, starting location, ending location. Use your interdistrict mileage matrix to standardize distance between sites and district offices. Vague entries are audit red flags.

• Reconcile district vehicle vs. personal vehicle policies — If you reimburse mileage for personal vehicles but also provide district vehicles to some employees, document the logic and ensure no double-dipping on vehicle expenses.

T&E documentation requirements and what “maintained through the year” looks like

Core documentation requirements

The audit-proof expense file contains:

• Itemized receipt — Not just credit card slips. Must show: vendor name, transaction date, items purchased with individual prices, payment method, and total amount. For meals, must include a list of attendees and business purpose.

• Business purpose documentation — Generic descriptions fail audits. A vague entry like Dinner — $87 fails; a specific entry like Dinner while at Business Leaders Conference — $87 passes.

• Pre-approval documentation when required — If your policy requires pre-approval for certain expense categories (travel, conferences, entertainment), the approval must be dated before the expense date.

• Mileage logs with five required elements — Date, destination, business purpose, starting point, ending point.

• Conference/training justification — Agenda or course description, business relevance explanation, and supervisor approval. For multi-day events, document which days included business activities.

What “maintained through the year” actually means

Proper maintenance requires ongoing discipline.

Monthly maintenance checklist:

• Conduct monthly expense report audits — Don’t wait for year-end. Sample 5–10% of submitted expenses monthly. Check for: missing receipts, inadequate business purpose descriptions, policy violations, and mathematical errors if on paper.

• Run monthly exception reports — Flag: expenses submitted more than 60 days after occurrence, duplicate submissions, expenses just under approval thresholds (potential splitting), round-number expenses without receipts, and weekend/holiday expenses without explanation.

• Update your policy violation log — Track every policy exception granted. Document: employee name, violation type, business justification, approver, and date. This log proves you are monitoring compliance, not rubber-stamping violations.

• Maintain a running list of unclear scenarios — When employees ask questions about expense eligibility, document the question and your answer. This becomes your FAQ and reveals policy gaps to address.

Quarterly maintenance checklist:

• Review and update approval hierarchies — Organizational changes happen constantly. Quarterly reviews catch reporting structure changes before they cause routing failures.

• Audit your vendor receipt quality — Some vendors provide inadequate receipts. Identify problematic vendors and create supplementary documentation requirements for those transactions.

• Test your expense system reporting capabilities — Ensure you can quickly generate reports by: employee, department, expense category, date range, and approval status. Fix it before audit season if you cannot produce these reports easily.

Annual maintenance checklist:

• Conduct a full policy review — Compare your written policy to actual practice. Where they diverge, either update the policy or retrain staff. Auditors look for policy-practice gaps.

• Archive documentation systematically — Establish retention periods (typically 7 years for tax purposes). Use consistent naming conventions: ExpenseReport_EmployeeLastName_YYYYMMDD.

• Create an audit response kit — Compile: current T&E policy, approval hierarchy documentation, rate schedules used throughout the year, training materials provided to staff, and sample expense reports demonstrating compliance.

• Document system changes and effective dates — If you changed expense systems, updated policies, or modified rates mid-year, create a timeline showing what rules applied when.

The often-forgotten documentation elements

• Split-funded expense allocation — When expenses are charged to multiple budget codes, document the allocation methodology and maintain consistent application.

• Expense report amendment trail — If an expense report is corrected after approval, maintain both versions with explanation of changes and re-approval documentation.

• Employee Policy Acknowledgement — Use the start of the school year to communicate T&E policies. Send the policy and have each employee acknowledge receipt.

Final preparation step: Schedule a mock audit 30 days before your actual certification deadline. Select 20 random expense reports from the past year and verify you can produce complete documentation for each within 24 hours. Gaps discovered now are fixable. Gaps discovered during the actual audit are not.
