I am a 65 year old disabled man living on SS disabiltiy income. Can anyone tell me if I must file income tax return for 2008 to receive any stimulus payment on the President's new Bill? And anyone know how much the retired/disabiled will get? Thank you

My advice is to file. SS income may qualify you for a payment as it did in 2008.
Since SS benefits are not taxable to you as you describe your situation your tax will be zero and you might get some cash if there is a new stimulus payment.
