Hi Epi,
Even if you used student loans to pay tuition you may be able to deduct the cost of work-related education expenses paid during the year if you're a self-employed individual and your expenses must be for education that (1) maintains or improves skills needed in your present work or (2) a law requires to keep your present salary, status or job. However, even if the education meets either of these tests, the education can't be part of a program that will qualify you for a new trade or business or that you need to meet the minimal educational requirements of your present trade or business.

If going to school is necessary for your business, you may be able to write the tuition off on your taxes. Employees have to claim business-related education as an itemized tax deduction but if you're self-employed, you deduct tuition and other educational costs off the self-employment income you report on Schedule C. Your deduction not only lowers the income subject to income tax but to self-employment tax -- a 15.3 percent tax as of 2011. You must make sure your education qualifies as a business expense before claiming the write-off

Hope this helps,
