I could help you better if you clarified what you mean by checking the tax status of your company. If you filed tax returns for a C corporation and included a federal ID number, as your question indicates, then the IRS would have that on record and expect a tax return from you this year, provided you didn't notify them that you were no longer in business.
You can not get a transcript of a form 1120 corporate tax return on line or by email, you would have to mail in a completed form 4506 to request it by mail.
