You can continue to take the deduction for the amount of student loan interest you pay each year, after you have graduated and until the loans are paid off. The amount you can deduct is limited by your Adjusted Gross Income.
For 2018, the maximum amount that you can deduct for interest paid on student loans remains $2,500. Phaseouts apply for taxpayers with MAGI in excess of $65,000 ($135,000 for joint returns) and is completely phased out for taxpayers with MAGI of $80,000 or more ($165,000 or more for joint returns)
