Lawmakers on Capitol Hill are considering limiting employee health care flexible spending accounts.
The health care reform legislation could include a back-door tax hike. Flexible spending accounts are currently tax free.
Workers put money into the accounts to pay for dental work, co-payments and some medications.
Currently, there is no cap on annual employee contributions, but proposed legislation would cap contributions at $2,500.
That would limit the employee income tax exemption, and result in a tax increase.
Lawmakers said this would raise more than $13 billion over the next ten years.
