If you or your parents are filing a 2010 income tax return, we recommend filing it before completing the FAFSA. However, the income tax return does not need to be sent to the IRS before filling out your FAFSA. Also, you can estimate your taxes if you plan to complete them later in the year. If you estimate, you should estimate as close to your actual anticipated income as possible; you will be required to provide your actual tax information once it is available.
