Yes, you can deduct those unreimbursed expenses as an itemized deduction on your tax return.
If you can itemize your deductions for 2019 then you can deduct your unreimbursed expenses on Schedule A Gifts to Charity Line 12
However, for most taxpayers, their standard itemized deduction is higher than their itemized deductions and they do not itemize.
The 2019 standard deductions are: $12,200 if you are single or use married filing separate status $24,400 if you file e a married joint-file and $18,350 if you file as head of household.
