Did you get disability insurance payments in 2011?  

If you received Short-term or Long-term Disability Insurance payments in 2011, you should have received a W-2. This W-2 reflects any taxable and nontaxable amounts paid under the ERS disability plan. You should include this W-2 with all other documents you provide to your tax preparer.

Consult with your tax advisor regarding the tax implications of any benefits you received. If you then wish to initiate or change the withholding of federal income taxes from your monthly Long-term Disability benefit, contact your Claims Representative toll-free at (855) 377-5433 and request a copy of form W-4S.
