<prompt> Human: Credit Karma says I can file my taxes with them for free, and get an advance on my refund with no fees or interest. Why? What do they get out of it? Has anyone used this before?Assistant: From their press releaseAmericans can receive an Earlybird Advance on a new American Express Serve Prepaid Card just days after the IRS accepts their tax return from Credit Karma Tax.So my guess is that it is to raise usage of the American Express Serve cards.Human: Okay, that is making more sense now. I have a Square account, so theoretically, I could just run the 1000 through that and get 975 deposited right into my account. Doesnt sound horrendous...  <response>: Every time Ive filed my federal return, Ive gotten the refund deposited into my bank account in 2 weeks tops, often less than that. Unless theyre sending that prepaid card to you with overnight shipping, youre paying 25 for the privilege of having your refund MAYBE a week earlier, if that. Hell, you may very well have your refund deposited into your account before the card even arrives in the mail.
