I've taken a Designlab course before, how can I declare this expense for tax purposes?

Designlab does not issue 1098 forms, as it is not considered an "eligible education institution" according to IRS terminology. http://www.irs.gov/publications/p970/ch12.html#en_US_2014_publink1000178645

if you have any questions regarding reporting your Designlab expense for tax purposes, please consult with your tax advisor. Designlab does not provide tax, legal, or accounting advice. This article is meant to be used for informational purposes only.
