Any downside to submitting CSS profile early?

We have to submit the CSS profile by 11/15 for an EA school. S will be applying to 3 more colleges that use the profile RD so for those schools the form is not due until 2/15 at the same time as the FAFSA. I have filled out the Profile with estimated 2015 info for the EA school and I don’t expect the information to change significantly between now and 2/15. Is there any reason that I can’t submit to all 4 colleges now and just be done with it? Or should I submit the 1 EA and then update the form and submit the others in Jan/Feb? (The website indicates that changes can be made online for colleges where the form has not yet been submitted.)

You’ll have to update each one separately with final numbers. Some schools will want pen and ink corrections, others may want a copy of the tax forms. I would wait to submit final on the others just the one time.

Wait until 2/15, you should have your tax ready. The CSS will be final
