business today inc.

My lawyer created an incorporation (Inc.) in 2000 for me. I was planning to start to my own business but I got a good job offer that time so never had time to start my own business. I paid minimum tax fee ($100) only once. So Do I owe any taxes till now? It’s a New York Corporation, I have all the certificated documents, a seal, shareholder papers etc.
Can I use this company today to apply an merchant ID number? I am not US citizen but I have SSN and an US Bank account. I am not living in US at the moment but I can provide a business address.
What should I do? Should I try to create a new business and forget about this old one?

Thanks in advance for your advices
