Each year the unclaimed tax refunds due to Americans, is mounting for various reasons. Some people do not file returns because they don’t owe taxes. However, without documentation, these folks won’t get any due to refunds either. The IRS does not send refunds until a Form 1040 (or 1040A or 1040EZ) is filed with them that details just how big the government’s check should be.
Other taxpayers have income tax withheld but did not file returns because they earned too little. However, the only way to get the withheld money back is to file a return.
