If there is not an average daily commute, enter zero.
If you have entered zero and you are getting an error message with
regard to commuting miles, then there may be a problem with the other mileage
amounts that you entered.
When you enter vehicle
expenses for any purpose (Schedule C, Schedule E, Form 2106) in your tax
return, you are asked to enter the number of miles driven for the entire year,
the number of miles driven for business purposes, and the number of commuting
miles.
These values are used to
determine how much (what percentage) your car was used for business
purposes.
The assumption is
that: total number of miles driven - business miles - commuting miles =
personal miles.
If you are seeing an error
message it is telling you that for the
numbers that you entered, there was nothing left over for personal miles. The business miles + commuting miles was
greater than the total. So, the program
assumes that the error is in the number of commuting miles.
You should revisit the
section where the miles was entered to be sure all of your numbers are
accurate. But remember, the total must be greater than business + commuting.
