If anyone can help me I would really appreciate it. In my Pay stubs I realize i get tax pre tax and post tax on both my dental and vision insurance? why is that? why do they take it out twice?
Domestic partner benefits are generally not qualified for tax-exempt status under employer Section 125 cafeteria plans. This is an IRS regulation that has nothing to do with your particular plan.
What you're seeing is the tax-free contribution for yourself (and possibly dependents), and an after tax contribution for your domestic partner. Sometimes this appears as a separate contribution, sometimes the contribution toward the domestic partner is imputed as income and taxed that way.
