If you use a vehicle for certain driving purposes, you can deduct your costs based on your actual expenses or rely on an IRS-set mileage rate. The IRS has announced the standard mileage rates that can be used for deductible-driving costs in 2020 (Notice 2020-5). These rates apply for the use of a car, van, pickup, or panel truck:
If you use the standard mileage rate to figure your deduction for business use of a vehicle, you must reduce the basis of the vehicle by a cents-per-mile rate. For 2020, the rate is 27 cents per mile (up one cent from the 2019 rate).
Advance payment of current tax liability based either on wage withholdings or installment payments of your estimated tax liability. To avoid penalties, you generally must pay to the IRS either 90% of your final tax liability, or either 100% or 110% of the prior year’s tax liability, depending on your adjusted gross income.
