my tax return? My only income came, by monthly check. I don't receive any type of form, showing the yearly amount. So, I'm not sure how to show/prove what I've made.
If you're asking about the stimumlus plan payments you need to file a tax return to receive one. Since your income isn't taxable you need to file a special Form 1040-A tax return this year to show your qualifying income. Here's a link to a sample: http://www.irs.gov/pub/newsroom/1040a.pdf And here's a link to some more VA specific information: http://www.irs.gov/newsroom/article/0,,id=179203,00.html
Is it from the DOD or from the VA? VA Disability Compensation is nontaxable. VA sends an annual letter (usually in January) notifying you of the amount.
