If you went with direct deposit, your refund will be deposited into your same bank account. if you requested a check on your 2007 return, you will get that. If you went to a company and had it done and had an Assisted Refund, or Refund Anticipation Loan (RAL) you will receive a check in the mail. It will be sent to whatever address was used on your 2007 tax return. You MUST file a 2007 return in order to be eligible for the tax rebate.
