AMAP vs Employer Reimbursement
Understand the gap between HMRC approved mileage amounts and what an employer actually reimburses.
What HMRC AMAP tells you
- AMAP shows the approved benchmark amount for the miles and vehicle type.
- It is the baseline needed to judge whether relief may exist.
- It stays aligned to published HMRC mileage guidance.
- It helps normalize policy comparisons across employers.
What employer reimbursement tells you
- Employer reimbursement is the amount you were actually paid.
- It may match, exceed, or fall short of the approved amount.
- It is the operational input for expense claims and payroll.
- It is the figure that matters when estimating any shortfall for relief.

Decision checklist

- Will the same analysis need to be explained to payroll or tax advisers later?
