You are permitted to use your medical FSA plan to pay for eligible healthcare expenses for you and your eligible dependents. In general an eligible dependent is:
- Your Spouse
- Your dependent that you can claim on your tax return
- Your adult child(ren) who is under the age of 27.
A domestic partner is not considered a spouse under federal law, so a domestic partner's medical expenses cannot be reimbursed under your medical FSA account unless the domestic partner is a qualifying relative as described above. A qualifying spouse must be legally married.
