Military Leave - Tax treatment of made up contributions for prior years.

[Guest 2341mid]

For someone who wishes to make up missed deferrals while on a 6 month leave in 2003, are those deferrals reported on his 2004 w2 along with his "regular" deferrals made in 2004? Or would he have to file an amended 2003 return? In our case, he would end up with a total of about $19k total deferred. Still working with our recordkeeper on how they will account for the made up deferrals, given the limits built into their system.
