I own a duplex the when I enter the mortgage interest and water bill for the building do I enter the full amount of interest and water bill and turbo tax will calculate half or do I enter half of the interest and water bill
Yes. Enter the full amount of each of your expenses and Turbo Tax will calculate the amount that is deductible as a rental expense as well as any amounts that you can take as itemized deductions, if you qualify to itemize.
To enter your expenses in Turbo Tax:
log in to your Turbo Tax account
click on "take me to my return"
click on "federal taxes" tab
click on "wages and income"
scroll down to rental properties and royalties" and click on "edit/add"
Turbo Tax will start asking you questions about your rental property. Be sure to indicate that you are renting out a duplex that you also live in.
You will see a screen that says, "let us calculate your expense deductions for you". Answer "yes" I will enter total amounts and let Turbo Tax do the math.
