No, most of what you have listed is not deductible. If you have to go to the post office, the mileage from start to the post office and back to your original location is deductible. If there are any personal miles within this trip, subtract them. See Pub 463 for more information.
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 the city or general area that is your tax home. Tax home is defined in chapter 1.
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.
Transportation expenses don’t include expenses you have while traveling away from home overnight. Those expenses are travel expenses discussed in chapter 1 . However, if you use your car while traveling away from home overnight, use the rules in this chapter to figure your car expense deduction. See Car Expenses , later.
Daily transportation expenses you incur while traveling from home to one or more regular places of business are generally nondeductible commuting expenses. However, there may be exceptions to this general rule. You can deduct daily transportation expenses incurred going between your residence and a temporary work station outside the metropolitan area where you live. Also, daily transportation expenses can be deducted if: (1) you have one or more regular work locations away from your residence or (2) your residence is your principal place of business and you incur expenses going between the residence and another work location in the same trade or business, regardless of whether the work is temporary or permanent and regardless of the distance.
Trip Primarily for Personal Reasons
If your trip was primarily for personal reasons, such as a vacation, the entire cost of the trip is a nondeductible personal expense. However, you can deduct any expenses you have while at your destination that are directly related to your business.
A trip to a resort or on a cruise ship may be a vacation even if the promoter advertises that it is primarily for business. The scheduling of incidental business activities during a trip, such as viewing videotapes or attending lectures dealing with general subjects, won’t change what is really a vacation into a business trip.
