Same here, I didnt fill in the tax info, and we were selected.

The problem with the online and paper EOIs differing is that its free to update the website but costs a bomb to make changes with the paper version, so the paper version is a little out-dated.

Rule of thumb: if the online EOI lets you do it, then it must be ok! It wouldnt have allowed you to submit your EOI if it wasnt complete.
