What do you mean by lost out? Is a return just the amount you overpaid in taxes?
Sweet baby jesus. THAT IS A REFUND!
The "return" is all that paperwork you fill out to determine if you have to pay or get a REFUND.
Okay, my question still stands if you replace the word dude. What's he missing out on if it's just money you over paid?
He could have given the government more than he owed. He would have got that money back if he filed. He missed out.
