An Oklahoma resident may deduct nonrecurring adoption expenses up to $20,000 per year. Only expenses from 2020 may be deducted. Qualifying expenses include adoption fees, court costs, medical expenses, attorney fees, and expenses which are directly related to the legal process of adoption of a child.
You should have a schedule describing the expenses claimed. If you are mailing your return, include the schedule with your tax return. If you are e-filing, keep the schedule in your records for three years in case the Oklahoma Tax Commission requests it.
