In 2018 I went to the Mayo Clinic in PHX FROM ABQ 10X, can I claim mileage since I was never reimbursed for anything on these trips?

Since there are a lot of factors that go into calculating whether it's worth while amending your return for medical mileage, I recommend you go through the amend process. You don't have to file it if it doesn't make a difference.

• Figure out the dollar amount of your medical mileage, 10 round trips from ABQ to PHX. The 2018 medical mileage rate is 18 cents per mile. 
• In order to claim this deduction, filers must itemize their taxes. The provision of the Tax Cuts and Job Act that doubles the standard deduction — to $12,000 for individuals and $24,000 for joint filers 
• You can deduct the portion of medical expenses that exceeds 7.5% of your adjusted gross income (AGI).
