Pub. 17, Chapter 28 - Car Expenses & Other Employee Business Expenses
This section discusses expenses you can deduct for local business
transportation. This includes the cost of transportation by air, rail,
bus, taxi, etc., and the cost of driving and maintaining your car.
Local transportation expenses include the ordinary and necessary
costs of all of the following.
- Getting from one workplace to another in the course of your business
or profession when you are traveling within your tax home. (Tax home is
defined earlier under Travel Expenses.)
- Visiting clients or customers.
- Going to a business meeting away from your regular workplace.
- Getting from your home to a temporary workplace when you have one or
more regular places of work. These temporary workplaces can be either within
the area of your tax home or outside that area.
Local business transportation does not include expenses you have
while traveling away from home overnight. Those expenses are deductible
as travel expenses, which are discussed earlier. However, if you use your
car while traveling away from home overnight, use the rules in this section
to figure your car expense deduction. See Car Expenses, later.
The following discussions apply to you if you have a regular or main
job away from your home (residence). If your principal place of business
is in your home, see Office in the home, later.
        Illustration of local transportation. Figure 28-B illustrates
          the rules for when you can deduct local transportation expenses when
          you have a regular or main job away from your home. You may want to
          refer to it when deciding whether you can deduct your local business
          transportation expenses.
        Temporary work location. If you have one or more regular
          places of business away from your home and you commute to a temporary
          work location in the same trade or business, you can deduct the expenses
          of the daily round-trip transportation between your home and the temporary
          location.
If your employment at a work location is realistically expected to
last (and does in fact last) for one year or less, the employment is temporary
unless there are facts and circumstances that would indicate otherwise.
If your employment at a work location is realistically expected to last
for more than 1 year or if there is no realistic expectation that the employment
will last for 1 year or less, the employment is not temporary, regardless
of whether it actually lasts for more than 1 year. If employment at a work
location initially is realistically expected to last more than 1 year,
that employment will be treated as temporary (unless there are facts and
circumstances that would indicate otherwise) until your expectation changes.
It will not be treated as temporary after the date you determine it will
last more than 1 year.
         The
          above definition of "temporary work location" is the result of a recent
          change. Under the former definition, "temporary" meant an irregular
          or short-term basis (generally a matter of days or weeks).

         You
          can file an amended return on Form 1040X, Amended U.S. Individual Income
          Tax Return, for any year that is affected by this change. However, you
          generally must file the amended return within three years from the time
          you filed the original return or within two years from the time you
          paid the tax, whichever is later.

Figure 28-B. Local Transportation
If you have no regular place of work but ordinarily work in the metropolitan
area where you live, you can deduct daily transportation costs between
home and a temporary work site outside that metropolitan area. Generally,
a metropolitan area includes the area within the city limits and the suburbs
that are considered part of that metropolitan area. You cannot deduct daily
transportation costs between your home and temporary work sites within
your metropolitan area. These are nondeductible commuting costs.
If the temporary work location is beyond the general area of your
regular place of work and you stay overnight, you are traveling away from
home. You may have deductible travel expenses as discussed earlier in this
chapter.
        Two places of work. If you work at two places in one day,
          whether or not for the same employer, you can deduct the expense of
          getting from one workplace to the other. However, if for some personal
          reason you do not go directly from one location to the other, you cannot
          deduct more than the amount it would have cost you to go directly from
          the first location to the second. Transportation expenses you have in
          going between home and a part-time job on a day off from your main job
          are commuting expenses. You cannot deduct them.
        Armed Forces reservists. A meeting of an Armed Forces reserve
          unit is a second place of business if the meeting is held on a day on
          which you work at your regular job. You can deduct the expense of getting
          to or from one workplace to the other as just discussed under Two
          places of work.
You usually cannot deduct the expense if the reserve meeting is held
on a day on which you do not work at your regular job. In this case, your
transportation generally is considered a nondeductible commuting cost.
However, you can deduct your transportation expenses if the location of
the meeting is temporary and you have one or more regular places of work.
If you ordinarily work in a particular metropolitan area but not
at any specific location and the reserve meeting is held at a temporary
location outside that metropolitan area, you can deduct your transportation
expenses.
If you travel away from home overnight to attend a guard or reserve
meeting, you can deduct your travel expenses. These expenses are discussed
earlier under Travel Expenses.
        Commuting expenses. You cannot deduct the
          costs of taking a bus, trolley, subway, taxi, or of driving a car between
          your home and your main or regular place of work. These costs
          are personal commuting expenses. You cannot deduct commuting expenses
          no matter how far your home is from your regular place of work. You
          cannot deduct commuting expenses even if you work during the commuting
          trip.
        Example. You had a telephone installed in your car. You
          sometimes use that telephone to make business calls while commuting
          to and from work. Sometimes business associates ride with you to and
          from work, and you have a business discussion in the car. These activities
          do not change the trip from personal to business. You cannot deduct
          your commuting expenses.
        Parking fees. Fees you pay to park your car at your place
          of business are nondeductible commuting expenses. You can, however,
          deduct business-related parking fees when visiting a customer or client.
        Advertising display on car. Putting display material that
          advertises your business on your car does not change the use of your
          car from personal use to business use. If you use this car for commuting
          or other personal uses, you still cannot deduct your expenses for those
          uses.
        Car pools. You cannot deduct the cost of using your
          car in a nonprofit car pool. Do not include payments you receive from
          the passengers in your income. These payments are considered reimbursements
          of your expenses. However, if you operate a car pool for a profit, you
          must include payments from passengers in your income. You can then deduct
          your car expenses (using the rules in this chapter).
        Hauling tools or instruments. Hauling tools or instruments
          in your car while commuting to and from work does not make your car
          expenses deductible. However, you can deduct any additional costs you
          have for hauling tools or instruments (such as for renting a trailer
          you tow with your car).
        Union members' trips from a union hall. If you get your
          work assignments at a union hall and then go to your place of work,
          the costs of getting from the union hall to your place of work are nondeductible
          commuting expenses. Although you need the union to get your work assignments,
          you are employed where you work, not where the union hall is located.
        Office in the home. If you have an office
          in your home that qualifies as a principal place of business, you
          can deduct your daily transportation costs between your home and another
          work location in the same trade or business. (See chapter
          30 for information on determining if your home office qualifies
          as a principal place of business.)
If your home office does not qualify as a principal place of business,
follow the general rules explained earlier.
        Examples of deductible local transportation.
          The following examples show when you can deduct local transportation
          expenses based on the location of your work and your home.
        Example 1. You regularly work in an office in the
          city where you live. Your employer sends you to a one-week training
          session at a different office in the same city. You travel directly
          from your home to the training location and return each day. You can
          deduct the cost of your daily round-trip transportation between your
          home and the training location.
        Example 2. Your principal place of business is in your home.
          You can deduct the cost of round-trip transportation between your qualifying
          home office and your client's or customer's place of business.
        Example 3. You have no regular office, and you do not have
          an office in your home. In this case, the location of your first business
          contact is considered your office. Transportation expenses between your
          home and this first contact are nondeductible commuting expenses. Transportation
          expenses between your last business contact and your home are also nondeductible
          commuting expenses. Although you cannot deduct the costs of these first
          and last trips, you can deduct the costs of going from one client or
          customer to another.
        Car Expenses
If you use your car for business purposes, you may be able to deduct
car expenses. You generally can use one of two methods to figure your expenses:
actual expenses or the standard mileage rate. In this chapter, "car" includes
a van, pickup, or panel truck.
         You
          may be entitled to a tax credit for an electric vehicle (see chapter
          38) or a deduction from gross income for a part of the cost of a
          clean-fuel vehicle that you place in service during the year. The vehicle
          must meet certain requirements, and you do not have to use it in your
          business to qualify for the credit or the deduction. For more information,
          see chapter 15 of Publication 535.

          must meet certain requirements, and you do not have to use it in your
          business to qualify for the credit or the deduction. For more information,
          see chapter 15 of Publication 535.
Standard Mileage Rate
You may be able to use the standard mileage rate to figure the deductible
cost of operating your car for business purposes. For 1999, the standard
mileage rate is 32 1/2 cents a mile for all business miles driven
before April 1. The rate is 31 cents a mile for business miles driven
after March 31. This rate is adjusted periodically.
         If
          you can and do choose to use the standard mileage rate for a year, you
          cannot deduct your actual car expenses for that year.
If
          you can and do choose to use the standard mileage rate for a year, you
          cannot deduct your actual car expenses for that year.
You generally can use the standard mileage rate regardless of whether
you are reimbursed and whether any reimbursement is more or less than the
amount figured using the standard mileage rate. See Reimbursements under
How To Report, later.
        Rural mail carriers. If you are a rural mail
          carrier, you may be able to treat the amount of qualified reimbursement
          you received as the amount of your allowable expense. Because the qualified
          reimbursement is treated as paid under an accountable plan, your employer
          should not include the amount of reimbursement in your income. And,
          since the reimbursement equals the expense, you have no deduction to
          report on your tax return.
A "qualified reimbursement" is the amount of reimbursement you receive
that meets both of the following conditions.
- It is given as an equipment maintenance allowance (EMA) to employees
of the U.S. Postal Service.
- It is at the rate contained in the 1991 collective bargaining agreement.
Any later agreement cannot increase the qualified reimbursement amount
by more than the rate of inflation.
See your employer for information on your reimbursement.
         If
          you are a rural mail carrier and received a qualified reimbursement,
          you cannot use the standard mileage rate.
If
          you are a rural mail carrier and received a qualified reimbursement,
          you cannot use the standard mileage rate.
        Choosing the standard mileage rate. If you
          want to use the standard mileage rate for a car you own, you must choose
          to use it in the first year the car is available for use in your business.
          Then in later years, you can choose to use either the standard mileage
          rate or actual expenses.
If you want to use the standard mileage rate for a car you lease,
you must use it for the entire lease period. For leases that began on or
before December 31, 1997, the standard mileage rate must be used for the
entire portion of the lease period (including renewals) that is after that
date.
If you choose to use the standard mileage rate, you are considered
to have chosen not to use the depreciation methods under the Modified Accelerated
Cost Recovery System (MACRS). This is because the standard mileage rate
includes an allowance for depreciation. Also, you cannot claim the section
179 deduction if you use the standard mileage rate. If you change to the
actual expenses method in a later year, but before your car is considered
fully depreciated, you have to estimate the remaining useful life of the
car and use straight line depreciation. For information on how to figure
that depreciation, see the exception in Methods of depreciation under
Depreciation Deduction in chapter 4 of Publication
463.
        Standard mileage rate not allowed. You cannot
          use the standard mileage rate if you:
        
- Use the car for hire (such as a taxi),
- Operate two or more cars at the same time (as in fleet operations),
- Claimed a depreciation deduction using ACRS or MACRS depreciation in
an earlier year,
- Claimed a section 179 deduction on the car,
- Claimed actual car expenses after 1997 for a car you leased, or
- Are a rural mail carrier who received a qualified reimbursement. (See
Rural mail carriers, earlier.)
Two or more cars. If you own two or more cars that are used
          for business at the same time, you cannot use the standard mileage rate
          for the business use of any car. However, you may be able to deduct
          your actual expenses for operating each of the cars in your business.
          See Actual Car Expenses in chapter 4 of Publication
          463 for information on how to figure your deduction.
You are not using two or more cars for business at the same
time if you alternate using (use at different times) the cars for business.
        Example 1. Marcia, a salesperson, owns a car and a van that
          she alternates using for calling on her customers. She can use the standard
          mileage rate for the business mileage of the car and the van.
        Example 2. Maureen owns a car and a van that are both used
          in her housecleaning business. Her employees use the van and she uses
          the car to travel to the various customers. Maureen cannot use the standard
          mileage rate for the car or the van. This is because both vehicles are
          used in Maureen's business at the same time. She must use actual expenses
          for both vehicles.
        Parking fees and tolls. In addition to using the standard mileage rate, you
          can deduct any business-related parking fees and tolls. (Parking fees
          that you pay to park your car at your place of work are nondeductible
          commuting expenses.)
        
Actual Car Expenses
If you do not choose to use the standard mileage rate, you may be able
to deduct your actual car expenses.
         If
          you qualify to use both methods, figure your deduction both ways to
          see which gives you a larger deduction.
If
          you qualify to use both methods, figure your deduction both ways to
          see which gives you a larger deduction.  
        
  
    
      | 
         Actual car expenses include
          the costs of:  | 
    
      |  |  |  | 
    
      |  | 
    
      |  Garage rent |   Licenses | Repairs |

      |  Insurance |   Parking fees | Tolls | 
    
      |  | 
  
 
        Business and personal use. If you use your
          car for both business and personal purposes, you must divide your expenses
          between business and personal use. You can divide based on the miles
          driven for each purpose. 
        Example. You are a contractor and drive your car 20,000
          miles during the year: 12,000 miles for business use and 8,000 miles
          for personal use. You can claim only 60% (12,000 ÷ 20,000) of
          the cost of operating your car as a business expense.
        Interest on car loans. If you are an employee,
          you cannot deduct any interest paid on a car loan. This interest is
          treated as personal interest and is not deductible. However, if you
          are self-employed and use your car in that business, see chapter 8 of
          Publication 535.
         If
          you use a home equity loan to purchase your car, you may be able to
          deduct the interest. See chapter 25 for more
          information.
If
          you use a home equity loan to purchase your car, you may be able to
          deduct the interest. See chapter 25 for more
          information.
        Taxes paid on your car. If you are an employee,
          you can deduct personal property taxes paid on your car if you itemize
          deductions. Enter the amount paid on line 7 of Schedule A (Form 1040).
          (See chapter 24 for more information on taxes.)
          If you are not an employee, see your form instructions for information
          on how to deduct personal property taxes paid on your car.
You cannot deduct luxury or sales taxes, even if you use your car
100% for business. Luxury and sales taxes are part of your car's basis
and may be recovered through depreciation, discussed later.
        Fines and collateral. You cannot deduct fines
          and collateral you pay for traffic violations.
        Depreciation and section 179 deductions. If
          you use your car for business purposes as an employee or as a sole proprietor,
          you may be able to recover its cost by claiming a depreciation or section
          179 deduction. The amount you may claim depends on the year you placed
          the car in service and the amount of your business use.
For more information, see the instructions for Form 2106 (if you
are an employee) or Form 4562 (if you are self-employed). Also see chapter
4 of Publication 463 for a detailed discussion of
these deductions.
        Leasing a car. If you lease a car that you
          use in your business, you can use the standard mileage rate or actual
          expenses to figure your deductible car expense.
        Deductible payments. You can deduct the part of each lease
          payment that is for the use of the car in your business. You cannot
          deduct any part of a lease payment that is for personal use of the car,
          such as commuting.
You must spread any advance payments over the entire lease period.
You cannot deduct any payments you make to buy a car, even if the payments
are called lease payments.
        If you lease a car for 30 days or more, you may have to reduce your lease payment
          deduction by an "inclusion amount." For information on reporting lease
          inclusion amounts, see Leasing a Car in chapter 4 of Publication
          463.
        
Sale, Trade-in, or Other Disposition
If you sell, trade in, or otherwise dispose of your car, you may have
a taxable gain or a deductible loss. This is true whether you used the
standard mileage rate or actual car expenses to deduct the business use
of your car. Chapter 15 has information on sales
of property. For details on how to report the disposition, see Publication
544.
