I would like to know if it is possible to deduct from my taxes a couple of courses I took last year on Coursera. It's not a lot of money but if I can deduct them, all the better.
Usually, the costs of training courses (up to a certain limit) are tax deductable if such courses are directly relevant to your current employment. If you are studying for a change of career, or some non-vocational course, then these are not tax deductable.
When in doubt, put it in and let them argue to take it out, but be thoughtful about it, don't try to disguise it in anyway. If it is not 100% clear, they will often do a deal rather than an out denial.
