I rent my apartment. Is there a renter/s credit?

RENT

There is not a rent deduction or credit on your Federal return.  If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Rhode Island, Vermont, Washington DC, and Wisconsin.

there is no Federal credit but some states do have such a credit so you are going to have to tell us what state you resid in. 

There is no renter's credit at the Federal level.

Certain states offer tax credits to renters.

Please read this TurboTax Help article to check if your state is offering them.
