Because arthropods are characterized by bilaterally symmetric  segmented bodies, an exoskeleton made from chitin, and joint  appendages, pretty much any characteristic otherâ¦ than these might  disqualify the organism. Mammals for example, with their internal  skeleton would be disqualified.
Medical Expense Deduction. You can deduct medical mileage as part of your overall medical expense deduction. The IRS limits the medical deduction to the amount of medical expenses in excess of 7.5 percent of your Adjusted Gross Income.
Additionally, mileage can only be deducted if it exceeds 2% of the tax payerâs AGI (the adjusted gross income is lower than your gross income). So if you donât drive this much, you should ask your employer to reimburse you instead (or find a new job). The standard mileage rate for 2017 is 53.5 cents/mile.
