I bought a home this year with my girlfriend. We both use the property as our primary residence. She has children and I do not. We are not married, so we are filing separately. She is filing as head of household with her kids as dependents, and I am filing as single. Because she is filing as head of household, her standard deduction is larger than her itemizations, so she will not be itemizing her return. I am itemizing my return.
The 1098 for the property shows both of our names, but only my SSN, making me the payer of record. Since she is not itemizing her return, am I free to claim the full mortgage interest as a deduction on my tax return? The only information I can find from the IRS on this matter is from Publication 936 and reads as follows:
"More than one borrower. If you and at least one other person (other than your spouse if you file a joint return) were liable for and paid interest on a mortgage that was for your home, and the other person received a Form 1098 showing the interest that was paid during the year, at-tach a statement to your paper return explaining this. Show how much of the interest each of you paid, and give the name and address of the per-son who received the form. Deduct your share of the interest on Schedule A (Form 1040), line 8b, and print “See attached” next to the line. Also, deduct your share of any qualified mort-gage insurance premiums on Schedule A (Form 1040), line 8d.
Similarly, if you're the payer of record on a mortgage on which there are other borrowers entitled to a deduction for the interest shown on the Form 1098 you received, deduct only your share of the interest on Schedule A (Form 1040), line 8a. Let each of the other borrowers know what his or her share is."
I don't see anything that stipulates max or min percentages, or that interest claimed has to tie to ownership share of the property. Is there any further explanation or requirement placed on mortgage interest? Is there another policy or document with further details? Can we split the interest in whichever way we deem appropriate, so long as the joint total we claim as a deduction doesn't exceed the interest paid in Box 1 on the 1098?
