IRS benchmark vs employer policy

IRS benchmark and employer reimbursement are not the same thing

IRS benchmark

The optional standard mileage rate can be used for business mileage calculations and mileage allowances that meet applicable substantiation rules.

Employer policy

An employer can have its own reimbursement policy. The calculator's optional employer-rate field lets you compare a flat policy rate with the 2026 IRS benchmark.

State rules

State reimbursement requirements can differ. Do not assume the federal standard mileage rate by itself answers every employer reimbursement question.
