Having worked for a major American dance company, I know that you could combine your accounting and dance interests. Dance companies have finance departments within their organization requiring accountants to handle their finances. Your tax knowledge would be very beneficial and make you even more valuable to them (and more employable, too!). Your knowledge of dance would enhance your understanding of the needs of the dance company with an "insiders" perspective. As many dancers - especially ballet dancers - often have short professional careers because of the demands that are placed on the body, having a college degree and professional skills, like accounting and tax preparation, is necessary.
Also, with your tax knowledge, you could prepare to specialize in tax preparation for performing artists and fill that niche market. Demand for your services would spread quickly by word of mouth and advertising in dance magazines and through dance organizations, blogs, and other social media - and you could build a business quickly. The best way to determine how much to charge for these services would be to talk with an accountant and tax preparer who works with independent consultants and then adjust your fees for what the "market will bear." Dancers or other performing artists do not make as much money as, say, a financial hedge fund consultant, so you'd have to adjust your fee to what your clients can afford while still charging what you need to meet your living expenses.
I suggest that you call some dance institutions - major ballet or modern dance companies in your city - and arrange for an "informational interview" with the head of the accounting or finance office. Be prepared with your questions, does your homework of learning all you can about the company from their website, and dress professionally and be on time for your meeting. Take notes. If you can arrange for your interview notes to be published in your school newspaper -- with a photograph of who you interviewed - the company finance director would be even more inclined to be interviewed. And you'd do a real service to your fellow students.
Good luck! You're off to a great career!
