About what time does the IRS deposit your refund in your account?

If you chose to use Direct Deposit usually some time of the day on Friday but the first tentative refund cycle chart shows the first one could be possible DD January 29 2010.

To check on your refund, go to www.irs.gov and choose "Where's My Refund" or call the Refund Hot line at 800--829--1954. Please allow 72 hours after you electronically file and you receive your acknowledgment form the IRS that your return has been accepted as you filed it or 3 weeks after you mail your return before using the automated systems. You should also print a copy of the acknowledgment at the time that it is received by you. When you call, you will need to provide your Social Security number, your filing status, and the exact whole dollar amount of the refund shown on your return. There are several reasons for delayed refunds. Refer to Topic 303 for a checklist of common errors when preparing your tax return, and for additional items that may delay the processing of your return.

Be sure and read all of the message very carefully and you may need to print the message that you receive for your use in the future if you have a problem with your income tax return for some reason.
