After you file

They call it an advance  however it is really an interest free loan but you have to use the refund processing service for an extra fee AND open a bank account with Credit Karma this year to get access to the funds.  There is always red tape ... there is no "free lunch".   Since you are opening a bank account (with debit card access) they are allowed to be selective to whom they accept as clients  and banking regs lets them pull a credit report on you even if it is a "soft hit".
