Paul slipped on a wet spot in front of a computer store last July. He broke his ankle and was unable to work for two weeks. He incurred $1,300 in medical costs, all of which were paid by the owner of the store. The store also gave him $1,000 for pain and suffering resulting from the injury. ASCI did not pay his salary during the two weeks he missed because of the accident. However, ASCI's disability insurance plan paid him $1,500 in disability pay for the time he was unable to work. Under this plan, ASCI pays the premiums of $500 for the disability insurance as a taxable fringe benefit.The disability plan premiums and the disability benefit payments were not included in Paul's W-2 wages reported in paragraph 3.

how much of this do I add to disability in plan premiums/ benefits in order to get the proper net wages?
