“I did live there over 6 months, but, I moved back to az before I filed. But now she wont give copy of lease to me and all I have is an old 5 day notice on the OH address, and a receipt for rent payment. Is that enough to prove I DID qualify to file HOH, in Tax court?”------>I think so;as you can see, HOH is a tax filing status for unmarried individuals who paid more than 50 percent of the costs of keeping up the home for the tax year. Because of the benefits of this tax filing status, it can be abused. For this reason, it is important to be able to prove that you are qualified to file with this status if you do so.You need to locate proof that the kid you are supporting qualifies for the Qualified Person Test. You will need a copy of the birth certificate or placement order to prove the status of the qualifying person, as well as school, medical, daycare or other records to prove that the qualifying person resided with you at least six months out of the year. You ALSO need to gather documentation for the Cost of Keeping Up a Home Test. Make copies of any receipts related to rent, groceries, utilities, mortgages, and repair costs. Note that you should also make copies of any other household/ rent( payments) bills that prove you paid at least 50 percent of the costs of maintaining and running the home for the year.
