To the OP…the only real ways to reduce income are…
- Reduce your current job to part time...which will reduce your income.
- Quit your current job and get a lower paying job.
BUT remember…students filing the 2020-2021 financial aid forms are required to use the 2018 tax year info. And for 2021-2022, they will be required to use 2019. So…the above “solutions” are likely too late to do to impact financial aid for the next two years.
