Simple answer: no.
That said, it's theoretically possible; but from a
practical application, no. The rule is that you must have paid more than half
the household expenses. If you paid half, the other person (your father) must have paid less
than half.
If your situation closely matches the IRS "Acknowledged Significant
Advice" at the link below, you probably qualify. http://www.unclefed.com/ForTaxProfs/irs-wd/1998/1998-041.pdf
. It's a tough standard to meet and most living arrangements will not
qualify. If it's family and not unrelated people, like 2 single moms sharing a
residence, it's even more unlikely. If you try it, be prepared to prove it
with detailed accounting records of household expenses.
If your separate phone is a mobile, not a land line, that doesn't count as a household expense
