The Williams Institute & Center for American Progress: Unequal Taxes on Equal Benefits: The Taxation of Domestic Partner Benefits
Public policy encourages employers to provide health insurance by exempting that form of compensation from taxation. As a result, married workers who get family health insurance benefits get a double benefit–they get health insurance coverage for their spouses and children and are not taxed on the value of that coverage. In sharp contrast, workers who have an unmarried domestic partner are doubly burdened: Their employers typically do not provide coverage for domestic partners; and even when partners are covered, the partner’s coverage is taxed as income to the employee.
