No, there aren't plans in motion for everyone to receive another check next year. But if you weren't eligible to receive a check this year and become eligible next year, you can claim the economic stimulus payment next year on your 2008 tax return.
How do you know if you're eligible? The IRS says rebate eligibility depends if "you have a valid Social Security Number (SSN), can't be claimed as a dependent on a tax return and have either an income tax liability or "qualifying income" of at least $3,000." It's also important to note that, "both people listed on a "married filing jointly" return must have valid SSNs to qualify for the payment — if only one has a valid SSN, neither can receive the payment."
If any of these circumstances fall outside of your current situation but change by next year, then remember to claim the payment on next year's tax return so that you can get your rebate.
