#records
#records gathers notes about the written records behind a vehicle deduction. The posts describe a log kept at or near the time, what a later reconstruction can draw on, and the mileage totals a preparer needs for Form 4562 Part V. The page points at those records. It does not say which miles will be accepted.
General information, not tax advice.
