<p>I had a 3-4 month job experience. It was paid only in the summer (2months) when I became more involved with the organization. Will a college every ask to see the checks? or the 2ws? If so, I never scanned a check I got. Do I send a copy of my the tax returns?? Do I upload it (can you?) or mail it??</p>
<p>You don’t have to scan checks/tax forms, because the colleges will not request to see those documents. They’ll believe you. 
Just put it down as work experience. They have plenty of other things to worry about.</p>
