I rent a room at a friend's for more than 6 months can I claim renters credit?

Rent is not reportable or deductible on your Federal tax return. If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  

Some states have a renter's credit or deduction are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, Rhode Island, Vermont, and Wisconsin.

Of course, rules and regulations will vary by the state.

If you have any other details regarding this question, please feel free to post them in the comment section.
