@NJEngineerDad if the parents are married and didn’t file a joint return, they cannot use the IRS DRT because it won’t import both parent info.
@BelknapPoint as noted, the info transferred using the DRT is not visible when one reviews the form. But it should be correct assuming the info on the tax return is correct!
IIRC, the same log in information is also used for the Direct Loan promissory note as well as exit counseling when the student graduates. And for accessing account info for repayment purposes. Do you plan to keep your kid’s log in information a secret forever?
The easiest way to avoid having your kid see your FAFSA information is to NOT file a FAFSA. Have your kid look at colleges that award merit aid without having to file financial aid forms. There are way more of those than ones that do require the financial aid forms be filed. That way your student won’t ever need to see your income.
