You'll be able to submit your FAFSA® earlier. You can file your 2017–18 FAFSA as early as Oct. 1, 2016, rather than beginning on Jan. 1, 2017. The earlier submission date will be a permanent change, enabling you to complete and submit a FAFSA as early as October 1 every year.
Explanation: The FAFSA submission period for 2019-2020 is from October 1, 2018 to June 30 of 2020 and you present the tax information of 2017.
Those periods usually are the same independently of the period which you are postulating, none the less this may change, so it is useful to check it in their page to be sure of when you can submit the form
