I don't believe there is an income limit on using an FSA for dependent care. There may be limits if the covered person is a "highly compensated employee" for their particular employer, but that's not a hard dollar limit, it depends on the average salary of the particular employer. In general, with the changes to the tax brackets, the FSA will be better for anyone whose income is more than about $40,000, assuming they live in a state with state income tax.
