While you cannot choose single on your taxes when you're married, you can file as married filing separately instead. It's similar to filing as a single person, only you acknowledge the fact that you're legally married.
The one exception is for widows and widowers: the IRS still allows you to file as married (this is typically favorable for most taxpayers). Same sex couples who are married under state law are considered married for federal purposes. This includes not only income taxes but also gift and estate taxes.
