In late May, the Internal Revenue Service adopted a new position regarding taxation of registered domestic partners in its Private Letter Ruling 201021048 (the “PLR”). See Pender, Kathleen, “IRS adopts state domestic-partner property law,” San Francisco Chronicle (June 3, 2010) available at SFGate.com. Previously, the IRS did not apply California community property principles to registered domestic partnerships in terms of federal tax law since “[t]he relationship between registered domestic partners under the California Act is not marriage under California law.” See IRS Chief Counsel Advice 200608038.
However, now the IRS will treat the income earned by California registered domestic partners as community property income for federal income tax purposes. This means that each partner must report to the IRS one half of the total income earned between the two partners, not just his or her separate income. While this does not change the format in which the domestic partners must file their California state taxes, it may have significant federal tax benefits for partners with very disparate incomes.
