This is a "so what?" as far as your income tax return goes. The IRS does not care if you live together. If you are legally married then you can file a joint tax return or you can file married filing separately. A joint return is almost always a better way to file because of the way your credits and deductions work. If there is some sort of issue with your lease that is not a tax issue.
