The AICPA’s October 11 e-Alert reminds same-sex couples who are legally married to use the filing status married-filing-jointly on their extended income tax returns, due October 15.
Same-sex couples are considered legally married if regardless of where they life as long as their marriage took place in any domestic or foreign jurisdiction that recognizes the marriage. This treatment applies to any return filed on or after September 16, 2013.
