In many cases, any payments put toward your student loan interest is Tax Deductible. This has rapidly become important to me this year, as my wife and I pay ridiculous amounts to the student loan authorities of the world.
What are the requirements? Like nearly all adult student deductions, if you are married, you have to file jointly, or no go. You also have to make less than $65,000 a year (single) or $135,000 (joint).
