When you complete your FAFSA online, there will be a prompt that provides the option for the tax filer to voluntarily retrieve data using the IRS Data Retrieval Tool. If you select this option, you will be asked a series of questions to determine if you are eligible to use this tool. If so, your tax data will be retrieved directly from the IRS. This option is available 1 - 2 weeks after electronic tax filing - or - 6 to 8 weeks after paper tax filing. If you have not completed your taxes yet, you can still estimate your tax information in order to meet the appropriate financial aid filing dates. You can later file a correction to your FAFSA once you have filed your federal tax return.
