You report the rent received as income (on Sch. E). However your deductible expenses will most likely exceed your income, so you'll have no net taxable income.. Because this is your personal residence (in addition to being a rental property); and you use it most of the year (the 14 day or 10% rule), you are precluded from claiming any rental losses. You are only allowed to deduct expenses up to the amount of the income. Almost everybody in your situation comes out with a zero sum for tax purposes.

This means you cannot have a rental loss that lowers the tax owed on your other income, even if the rental activity turns out to be more expensive than you originally thought.”
