For the IRS under federal law:
The IRS does not recognize civil unions. Since same-sex marriages are legal, so the IRS now only allows you to file a federal return as married if you are legally married according to the laws of your state. You will need to file as single, or perhaps head of household if you pay more than half the cost of maintaining your home and you provide care in your home for a qualifying dependent (not your partner). Your partner might or might not file depending on their situation.
Then, you file a joint state tax return as RDPs, because state law allows you to file jointly.
This requires some jiggery-pokery in Turbotax. I think I know someone who can help,
