Some are well-meaning. Others are out to make a profit. Whatever their motives, some websites posting information about financial aid and FAFSA are inaccurate.
For example, the deadline to file a FAFSA is in June each year for the financial aid year that began the year before. June 30, 2020 is the deadline to file a FAFSA for the financial aid school year 2019-2020. What this means is that a student could start college in August 2019 and decide to file their FAFSA at the end of the school year and (assuming they do not owe their college any money) receive a retroactive payment for any grants for which they were eligible (assuming there were grant funds still available). This is not an advisable strategy, but is allowed.
I recently saw a web post from a company that promises to help clients with their financial aid, warning that June 30, 2020 was the deadline to file for aid for 2021. This is untrue.
Be careful where you get your financial aid information. The best sources are the financial aid office at your college, your college advisor if they have expertise in financial aid and the federal financial aid website: studentaid.gov.
