Many tax preparation firms offer their clients a refund anticipation loan (RAL). For a fee, the firm will give the client their refund on the day the return is filed. The loan is repaid when the IRS send the refund directly to the firm. Thus, the RAL fee is equivalent to the interest charge for the loan. The RAL schedule for a certain lender is below:
