A recent case confirms the requirement to maintain a contemporaneous, written log book in order to claim a deduction for business mileage expense. (Contemporaneous means recorded at the time of the activity, not based on a later recollection.)
The taxpayer reported more than 32,000 business miles on his 2014 tax return, but did not keep a log, calendar, or any records of the various work locations.
In 2017, the court disallowed the taxpayer’s mileage deduction.
Takeaway: Records must be contemporaneous and specific. Reconstructing written records years later is not contemporaneous, and estimating various details is not specific.
