Well, I don't normally need to file, but to try and get that rebate, I have to. Still, I won't get the amount everyone else gets, and maybe nothing.
You do need to file to receive the government payout. You have to file a 1040 and not a 1040EZ or another form. Most people will receive $800, but have to file to receive it. Those on medicare or SSI can receive $300, but have to file the basic form to get on the list for the check. You can file a request for extended time and still receive it, by filing before October (I think.)

Good wishes on those forms EJ!
