The main purpose of this legislation, known as the Volunteer Driver Tax Appreciation Act of 2025, is to change the way mileage is reimbursed for charitable driving. Specifically, it aims to align the mileage rate for charitable activities with the higher rate used for business travel. This change is intended to provide greater financial support for volunteers who use their personal vehicles to help others. The key provision of this legislation is the adjustment of the charitable mileage rate. Currently, the rate for charitable driving is set at 14 cents per mile.
