mileage reimbursement

Mileage reimbursement is a recurring topic here mainly through Microsoft Dynamics 365 Business Central, where the Expense Agent handles mileage claims for expense reporting. Recent coverage looks at a planned change under roadmap entry 573254 that moves Business Central away from a single flat mileage rate toward a set of rates defined by effective date range and vehicle type, with the agent applying the matching rate to each claim. The driver is practical compliance: the IRS changed its business mileage rate partway through 2026, so one standard rate field no longer fits U.S. companies that follow the IRS figure.
