Are there any schools that don't take tax forms?

<p>I've applied to the following schools:
-Purdue
-Columbia
-Cornell
-Caltech
-MIT
-CMU
-NU
-Case
-UPenn
-Rice
-Berkeley
-Michigan Ann Harbor
Most of the schools talk about needing tax documents sent(IDOC: MIT, Caltech, NU, Rice; Normal: cornell, CMU, Upenn). However, for some of the schools, I could not find any mentioning of needing tax forms. Is it standard procedure to just send tax forms to all your schools? Or can I just not send them for some?
So the following schools I have found nothing about:
Purdue, Columbia, Berkeley, Michigan,</p>

<p>Can someone help here? THanks</p>

<p>In our experience, most of the top schools that require Profile will ask for tax forms to back up the Profile. With FAFSA only schools, it seems that fewer require verification via tax forms. I’ve heard that around 30% are selected for verification.</p>

<p>Best to assume that you’ll need to back up your Profile or FAFSA applications with tax forms for all schools, IMO. So get the numbers right—</p>

<p>I looked up some more info. It seems that Purdue, Berkeley and Michigan will request for verification randomly. However, I’m still getting ambiguous answers from Columbia. Can someone who applied to Columbia this year confirm this?</p>
