Your EFC can be up to 1/3 of your annual income or higher if you have high asset value. If it is significantly higher than that you could have made a mistake. I have seen this happen with the IRS data retrieval tool, because you can’t see the tax figures once your taxes are imported into the FAFSA. If you used this tool I would recommend contacting the Financial aid office directly once your child is admitted and explaining the circumstances. It would also be worthwhile to log back into your FAFSA and be sure you didn’t inaccurately report something, I have seen this with so many families I have helped through the FAFSA process.
