Stimulus Payment Schedule for Tax Returns Processed by April 15   Economic stimulus payments will be issued according to the last two-digits of the main filer's Social Security number. For joint filers, the payments will go out based on the person listed first on the return. Payments will be made by either direct deposit or paper check, consistent with how people filed their 2007 tax return.   People who use direct deposit also will be among the first to receive the payments starting April 28. Direct deposits will be made daily and completed by the date listed below:   DIRECT DEPOSIT  Last two SSN digits:  Payments will be transmitted no later than:  00 through 20  May 2  21 through 75  May 9  76 through 99  May 16               Paper checks will also go out based on Social Security number. For Social Security numbers ending in 00 through 09, the paper checks will be mailed starting May 9 and will continue through May 16. A similar process will be repeated in the following weeks.   PAPER CHECK  Last two SSN digits:  Payments will be mailed no later than:  00 through 09  May 16  10 through 18  May 23  19 through 25  May 30  26 through 38  June 6  39 through 51  June 13  52 through 63  June 20  64 through 75  June 27  76 through 87  July 4  88 through 99  July 11                         People who file a return after April 15 will receive their economic stimulus payment, but probably about two weeks later than the schedule shows. A return must be filed by October 15 in order to receive a stimulus payment this year.   A small percentage of tax returns will require additional time to process and to compute a stimulus payment amount. For these returns, stimulus payments may not be issued in accordance with the schedule above, even if the tax return was processed by April 15.
