Volunteer Driver Tax Parity Act of 2022 This bill increases the rate of the tax deduction for the charitable use of a passenger automobile to equal the standard business rate (i.e., 58.5 cents per mile in the first half of 2022, then 62.5 cents per mile for the rest of that year) for taxable years beginning after 2021 and before 2024. It then provides for a permanent 24 cents per mile rate, adjusted annually for inflation, for taxable years beginning after 2023.
