I plead guilty to an OWI charge. I've paid over $2000 to the court and will be paying over $2000 in accumulated costs associated with mandatory drug and alcohol testing ordered by my probation officer. Having kept receipts, are those costs able to be deducted when doing taxes? Can I write off mileage to and from the testing location?
You'll need to consult with a tax attorney or other tax professional, particularly about whether mileage is deductible. It will all obviously depend on your overall tax situation; with the raised standard deduction starting with this tax year, a lot of people who used to itemize may no longer be able to do so, which would make your question a moot point if you are one of those people.
Very generally, I am unaware of allowable deductions for fines, fees, or costs related to criminal activities.
