It depends on the vehicle-related expenses that you have incurred during the year. If you’ve spent significant money on maintenance (oil changes, brake pad replacements, new tires, etc.), car inspections, and registration, then it may be more beneficial for you to use the actual expense method. On the other hand, if you’ve paid minimal expenses in the year or driven many miles for business, then the 56 cents per mile in 2021 may provide a larger expense deduction. It’s also simpler because you don’t need to keep detailed records of all your expenses. If you have kept all of your expense records, it is always beneficial to check your total expense deduction under both methods.
