He may have to and may have taxes due depending on the type of 1099 issued. Was it a 1099-Misc? then yes if it was income he earned working. There would be self employment taxes due. Was it a 1099-int, 1099-div or 1099-B? then no, there wouldn't be enough income to warrant filing a return if that's all there is.
