I have already filed my taxes can i get a loan without a bank account?

You can try BUT it will be very costly when and IF you can find any one that would want to furnish a loan to you using your possible anticipated FIT REFUND amount as collateral at this time in your life.
Hope that you find the above enclosed information useful. 03/13/2013

there are many businesses that offer short term loans and they may or may not accept you without a bank account
no bank will lend you any money but these independent companies specifically deal with people like you

some payday loan places don't require a bank account some do.
