Michelle:
First, if your AND your fiance's name is on the title for the house, then you can allocate the mortgage interest as you see fit. Just make sure that you properly allocate the interest and real estate taxes and do NOT double-claim it.
Second, email me at
[email protected] with your phone number so we can discuss the details of the Head of Household issue. It is too complex to discuss here.
Finally, in which state do you live?? The reason I ask is that you may already meet the criteria for a
common law marriage, which means you could file jointly. It is perfectly legal because the IRS WILL recognize a common law marriage if the state recognizes such marriages.
I know both Texas and South Carolina recognize common law marriage, and Georgia does NOT. A visit to your state government website should provide the answer!
