Google is going to begin covering a cost that gay and lesbian employees must pay when their partners receive domestic partner health benefits, largely to compensate them for an extra tax that heterosexual married couples do not pay. The increase will be retroactive to the beginning of the year.
Under federal law, employer-provided health benefits for domestic partners are counted as taxable income, if the partner is not considered a dependent. The tax owed is based on the value of the partner’s coverage paid by the employer.
The Kaiser Family Foundation says that 36 percent of large companies that offer health benefits provide coverage for same-sex domestic partners, and more than half of Fortune 500 companies provide domestic partner coverage — but few pay the extra costs of that coverage.
