Can you deduct more business miles that total miles on business vehicle if business vehicle needed repairs and you used another vehicle during repairs?

[AnnetteB · Accepted solution]

No, the program would not allow that calculation because it would cause errors.

If you paid a fee to use the replacement vehicle, then you could deduct the business portion of the fee as a business expense. 

If you used another vehicle that you own as a replacement vehicle, then you can enter it as a second vehicle used for business purposes in order to claim the business miles.
