Does Harvard Require the CSS Profile?
Harvard requires the CSS Profile for its own need-based aid and uses CSS code 3434. FAFSA alone is enough only when a student wants federal aid without Harvard grant aid.

These are the school's currently published 2026–27 dates. A late or updated application cycle can use different dates, so confirm the deadline shown in your applicant portal.
Which parent files?
Married parents or parents living together file one CSS Profile. If parents are separated or divorced, each parent files a separate CSS Profile. Harvard provides a waiver process when a parent cannot participate.
Documents and next steps
After filing the CSS Profile, applicants use IDOC to submit the required 2024 parent and student tax documents for 2026–27. Harvard says IDOC's default checklist is not the complete school-specific list, so follow Harvard's instructions too.
