I filed electronically several days ago and chose to have my refund deposited directly into my bank account, but I still haven't received my refund. What should I do?

If you filed electronically through a professional tax preparer, contact your preparer to make sure that your return was transmitted to us. A refund can also be delayed due to math errors, missing entries, questions about estimated taxes that were reportedly paid or incorrect bank account numbers. For more information, see Refunds and Choose Direct Deposit.
