Accountable Plan Mileage Reimbursement Checklist for 2026
If your employees drive personal cars for work, the reimbursement workflow matters as much as the rate. Use this checklist to keep mileage logs, approvals, and payroll exports cleaner.
The core accountable-plan rule set
IRS Publication 463 says an accountable plan must have a business connection, adequate accounting within a reasonable period, and return of excess reimbursement within a reasonable period. That gives small teams a concrete operating checklist: define the policy, collect trip evidence, approve the right miles, and preserve the export trail.

The 2026 mileage reimbursement checklist
Step 1
Define which drives are reimbursable
Separate business drives from normal commuting, personal errands, and mixed-purpose trips before employees submit logs.
Step 2
Require a business connection
Each reimbursed trip should connect to work performed for the employer, such as a client visit, job site, showing, inspection, delivery, or supply run.
Step 3
Collect mileage details within 60 days
IRS Publication 463 describes a 60-day safe-harbor period for employees to adequately account for expenses after they are paid or incurred.
Step 4
Pay only substantiated miles at the approved rate
For 2026, the IRS business standard mileage rate is 72.5 cents per mile. Teams can use a different policy, but the IRS rate is a simple planning anchor.
Step 5
Return excess advances within 120 days
If an employee receives more than they can support, the excess should be returned within the reasonable-period window described by IRS rules.
Step 6
Keep approval and export evidence
Store who approved the reimbursement, when it was approved, which trips were included, and what export was sent to payroll or bookkeeping.
Rate math: 72.5 cents per business mile
The IRS announced the 2026 business standard mileage rate at 72.5 cents per mile. For a small team, that turns missed logs into real money fast: 1,000 approved business miles equals $725 in reimbursement at the standard rate.

Split the workflow by role
Employee
Classify the trip as business, personal, commute, or mixed.
Add destination, purpose, and mileage while the context is fresh.
Attach tolls, parking, and related receipts to the same work context.
Manager
Approve only trips with clear business purpose and plausible routes.
Reject vague notes like work drive when the purpose is not obvious.
Confirm late submissions before payroll or reimbursement export.
Bookkeeper
Reconcile reimbursed miles against the approved policy rate.
Separate excess or unsupported amounts from accountable-plan payments.
Keep monthly exports and source logs together for audit support.
Red flags that can turn clean reimbursement into payroll cleanup
The biggest risk is not usually the mileage rate itself. It is missing support, stale submissions, and unsupported advances.
