Standard Mileage Rate vs. Actual Expenses
The Differences Between Them and How to Deduct Them On Your Taxes
If you have an automobile that you use for business, you may be able to deduct business travel expenses. Take a look at How to Deduct Travel Expenses on Your Taxes to help determine if you may be able to deduct your business travel expenses and what types of expenses you may be able to deduct.*
There are two ways to deduct these expenses. You can use the standard mileage rate or the actual vehicle expenses.
Standard Mileage Rate
You can only use the standard mileage rate if:
You cannot use the standard mileage rate if:
How to calculate standard mileage rate:
The standard mileage rate changes every six months to a year, so you must consult the current year’s tax form or your accountant for the current mileage rate. The mileage rate may be one number from January to June and something else from July to December.
In this deduction, you will calculate total miles driven and multiply it by the standard mileage rate.
For example: The mileage rate from January to June was .51. The mileage rate from July to December was .55. You drove 5,000 miles from January to June for business travel and 5,000 miles from July to December. Your standard mileage calculation would be as follows
2550 + 2750 = $5300 which would be your total, so you would reduce your tax basis by $5300.
If you use the standard mileage rate you cannot deduct:
You can still deduct business related:
- Parking fees and tolls.
- Interest if you have a loan on the car.
- Applicable registration fees and any taxes.
You can switch to using the actual expense method in later years even if you first began using the standard mileage rate. However, you cannot use accelerated depreciation. You will have to use the straight-line method of depreciation.
You must use actual expenses if:
- You have a fleet of vehicles (more than four) used simultaneously for your business activities.
- You lease a car and do not plan on using the standard mileage rate for the entirety of the lease.
- You used the actual expense calculation when your vehicle was first used for business purposes. You cannot switch to standard mileage rate in later years.
If you choose not to, or are unable to use the standard mileage rate, you can deduct the actual expenses associated with your vehicle. This includes but is not limited to:
- Interest on a vehicle loan
- Vehicle depreciation (leased vehicles cannot be depreciated)
- Registration fees and tax
- Parking fees and tolls
- Garage rent
- Lease payments (an income inclusion amount must be subtracted from the amount you can deduct if the vehicle’s value is above a certain amount. This amount changes yearly so be sure to check with the IRS or your accountant.)
- License plates
- Registration fees
For any of these expenses, you can only deduct the portion used for business.
For example: You drove 10,000 miles on your vehicle but only 6,000 were for business. So 60% (6,000 divided by 10,000) of your expenses were for business. Your actual expenses were $3000. 60% of $3000 ($3000 *.6) = $1800, so you could deduct $1800.
Standard Mileage Rate vs. Actual Expenses, Which Is Better?
It depends on the vehicle you drive and the operating costs of the vehicle. If your vehicle gets great gas mileage, then taking the standard mileage deduction will likely be more beneficial for you. If your vehicle has very high operating costs and low gas mileage, then taking the actual expense deduction may produce better savings for you.
*You should always consult the IRS or a certified accountant to decide what deductions are applicable to your specific situation.
