<prompt> Human: Ill probably end up making 90K this year. I know that the cut off for the student loan interest deduction is 80K and the amount you can claim is then calculated proportionally from that point i.e. the interest deduction available increases as gross income decreases. However, I was wondering if it would be a good idea to park some of my income into pre-tax vehicles like a 401K so my taxable my income would effectively fall below the cut off, and enable me to claim the interest deduction that I need probably 500.Thanks.  <response>: However, I was wondering if it would be a good idea to park some of my income into pre-tax vehicles like a 401K so my taxable my income would effectively fall below the cut off, and enable me to claim the interest deduction that I need probably 500.Its a good idea for two reasons - not only is being able to get a tax deduction a good thing, but contributing to your 401k is a good thing as well.
